Answer:
x = 36/7 (or approximately 5.143); y = 19/70 (or approximately 0.271)
Step-by-step explanation:
First, we can distribute the 2 to have both equations look similar:
[tex]2(0.5x-y)=4.6\\x-2y=4.6[/tex]
Now, we can eliminate the ys by multiplying the entire first equation by 2. This will allow us to solve for x.
[tex]2(0.2x+y=1.3)\\\\0.4x+2y=2.6\\x-2y=4.6\\\\1.4x=7.2\\x=\frac{36}{7}\\ x=5.142857143[/tex]
Now, we can plug in 36/7 for x in any of the two equations:
[tex]0.2(\frac{36}{7})+y=1.3\\ \frac{36}{35}+y=1.3\\ y=\frac{19}{70}\\ y=0.2714285714[/tex]
If you use the decimal answers, you can round as much as you need.

Answer:
f1(x) = (7 cos x - 3 sin x) tan-1 x + (7 sin x + 3 cos x) (1/(1+x^2))
Step-by-step explanation:
To find f1(x), we need to differentiate the given function f(x) with respect to x using the product rule and the chain rule. Here are the steps:
f(x) = (7 sin x + 3 cos x) tan-1 x
f1(x) = d/dx [(7 sin x + 3 cos x) tan-1 x]
= (7 cos x - 3 sin x) tan-1 x + (7 sin x + 3 cos x) (1/(1+x^2)) (d/dx)x
= (7 cos x - 3 sin x) tan-1 x + (7 sin x + 3 cos x) (1/(1+x^2))
Therefore, f1(x) = (7 cos x - 3 sin x) tan-1 x + (7 sin x + 3 cos x) (1/(1+x^2)).

one number is less than 3 times another if their sum is increased by 5 the result is 25 find the number
Answer:
Let's use algebra to solve the problem.
Let x be the first number.
Let y be the second number.
From the problem, we can set up two equations:
"One number is less than 3 times another":
x = 3y - - - (Equation 1)
"Their sum is increased by 5 the result is 25":
x + y + 5 = 25
x + y = 20 - - - (Equation 2)
Now we have two equations with two unknowns. We can use substitution or elimination to solve for one of the variables.
Using substitution:
From equation 1, we know that x = 3y. We can substitute this into equation 2 to eliminate x:
3y + y = 20
4y = 20
y = 5
Now we can substitute this value of y back into equation 1 to find x:
x = 3y
x = 3(5)
x = 15
Therefore, the first number is 15 and the second number is 5.

How to get the transpose matrix?Here we are given the matrix A, and we want to find the transpose matrix A^t.
To do so, just leave the elements in the diagonal as they are in the original matrix, and then do a "reflection" of the other elements along the diagonal line. So the elements with equal subindices stay where they are, and the others are reflected along them.
Then the new matrix will be:
[tex]\left[\begin{array}{ccc}3&2&0\\0&3&4\\0&0&3\end{array}\right][/tex]

Vanessa borrowed $5,000 at 4% simple interest and will pay after 2 years. Please help!!
a) How much will she have to pay?
b) How much interest will she pay?
Answer:
a) To calculate how much Vanessa will have to pay back after 2 years, we need to add the interest to the principal.
The interest can be calculated using the simple interest formula:
Interest = Principal x Rate x Time
where,
Principal = $5,000 (the amount borrowed)
Rate = 4% (expressed as a decimal, 0.04)
Time = 2 years
So,
Interest = $5,000 x 0.04 x 2
Interest = $400
The total amount Vanessa will have to pay back is the sum of the principal and the interest:
Total amount = Principal + Interest
Total amount = $5,000 + $400
Total amount = $5,400
Therefore, Vanessa will have to pay $5,400 after 2 years.
b) To calculate how much interest Vanessa will pay, we can use the same formula for simple interest:
Interest = Principal x Rate x Time
Plugging in the given values, we get:
Interest = $5,000 x 0.04 x 2
Interest = $400
Therefore, Vanessa will pay $400 in interest over the 2-year period.
Mateo y leo caminan para entrenar y encontrarse en un punto. Mateo camina 1/5 mas de lo que camina leo. Si entre los dos caminan 15Km, ¿ cuantos kilómetros recorre cada uno?
Answer:
Primero, podemos establecer las siguientes ecuaciones:
La suma de los kilómetros que caminan Mateo y Leo es igual a 15:
Mateo + Leo = 15
Mateo camina 1/5 más que Leo:
Mateo = Leo + 1/5Leo
Mateo = 6/5Leo
Podemos utilizar la segunda ecuación para despejar una de las variables en términos de la otra. Por ejemplo, despejando Leo:
Leo = 5/6Mateo
Luego, podemos sustituir esta expresión en la primera ecuación para obtener una ecuación con una sola variable:
Mateo + 5/6Mateo = 15
11/6Mateo = 15
Mateo = 15*6/11
Mateo = 8.18 Km
Finalmente, podemos utilizar una de las ecuaciones que relaciona a Mateo y Leo para obtener la distancia que recorre Leo:
Leo = 5/6Mateo
Leo = 5/6*8.18
Leo = 6.82 Km
Por lo tanto, Mateo recorre 8.18 Km y Leo recorre 6.82 Km.
 In a triangle, the second angle measures two times the first. The measure of the third angle is 170° more than the measure of the second. Find the measures of the three angles
Answer: Let's call the first angle "x".
From the problem statement, we know that the second angle is two times the first, so:
Second angle = 2x
We also know that the third angle is 170° more than the second angle, so:
Third angle = Second angle + 170°
Third angle = 2x + 170°
We know that the sum of the three angles in a triangle is 180°, so we can set up an equation:
x + 2x + (2x + 170°) = 180°
Simplifying and solving for x:
5x + 170° = 180°
5x = 10°
x = 2°
So the first angle is 2°. Using this value, we can find the other two angles:
Second angle = 2x = 2(2°) = 4°
Third angle = 2x + 170° = 2(2°) + 170° = 174°
Therefore, the three angles in the triangle measure 2°, 4°, and 174°.

One large jar and two small jars together can hold 8 ounces of jam. One large jar minus one small jar can hold 2 ounces of jam.
A matrix with 2 rows and 2 columns, where row 1 is 1 and 2 and row 2 is 1 and negative 1, is multiplied by matrix with 2 rows and 1 column, where row 1 is l and row 2 is s, equals a matrix with 2 rows and 1 column, where row 1 is 8 and row 2 is 2.
Use matrices to solve the equation and determine how many ounces of jam are in each type of jar. Show or explain all necessary steps.
Please help me solve it through matrices, not by equations. There's a certain way to solve this, I'm just confused on this specific way by using matrices.
There are 2 ounces of jam in the large jar and 2/3 ounce of jam in each small jar.
Describe Matrix?In mathematics, a matrix is a rectangular array of numbers, symbols, or expressions arranged in rows and columns. Matrices are commonly used to represent and manipulate linear transformations and systems of linear equations.
The elements of a matrix are typically denoted by lowercase letters with subscripts, such as aij or bij, where i and j refer to the row and column indices, respectively. For example, a 3x3 matrix might look like this:
| a11 a12 a13 |
| a21 a22 a23 |
| a31 a32 a33 |
This matrix has three rows and three columns, and the element in the first row and second column is denoted by a12.
Matrices can be added, subtracted, multiplied, and divided, and these operations follow specific rules that are defined in matrix algebra. For example, to add or subtract two matrices of the same size, we simply add or subtract the corresponding elements. To multiply two matrices, we multiply the rows of the first matrix by the columns of the second matrix and sum the products.
Let's represent the number of ounces of jam in the large jar as "L" and the number of ounces of jam in each small jar as "S". Then we can write the system of equations:
1L + 2S = 8
1L - 1S = 2
We can write this system in matrix form as:
[1 2; 1 -1][L;S] = [8;2]
To solve for L and S, we can use matrix algebra to isolate [L;S]:
[L;S] = [1 2; 1 -1]⁻¹ [8;2]
First, we need to find the inverse of the coefficient matrix [1 2; 1 -1]. The inverse is:
[1 -2; 1 1]/3
So we can substitute this into our equation:
[L;S] = [1 -2; 1 1]/3 [8;2]
[L;S] = [2;2/3]
So there are 2 ounces of jam in the large jar and 2/3 ounce of jam in each small jar.

Jason wants to buy a new HD television but he thinks that if he waits, the quality of HD televisions will improve. The television he wants to buy costs $2500 now, and based on pricing trends, Jason thinks that the price will increase by 4% each year. (SHOW ALL WORK)
a. Write an exponential growth equation to represent the price y of a new HD television t years from now.
b. Use the equation to predict when a new HD television will cost $3000.
c. Jason decides to wait to buy a new television and saves his money. He puts $2200 in a savings account with 4.7% annual interest compounded continuously. Determine when the amount in his savings will exceed the cost of a new television.
the amount in Jason's savings will exceed the cost of a new television approximately 7.22 years from now.
a. The exponential growth equation to represent the price y of a new HD television t years from now is:
y = $2500[tex](1 + 0.04)^t[/tex]
where t is the number of years from now.
b. To predict when a new HD television will cost $3000, we can set y = $3000 and solve for t:
$3000 = $2500[tex](1 + 0.04)^t[/tex]
1.2 = [tex]1.04^t[/tex]
ln(1.2) = t ln(1.04)
t = ln(1.2) / ln(1.04)
t ≈ 3.97
Therefore, a new HD television will cost $3000 approximately 4 years from now.
c. To determine when the amount in Jason's savings will exceed the cost of a new television, we can use the formula for continuous compound interest:
A = [tex]Pe^(rt)[/tex]
where A is the amount in savings after t years, P is the principal amount, e is the mathematical constant approximately equal to 2.71828, r is the annual interest rate expressed as a decimal, and t is the time in years.
In this case, P = $2200, r = 0.047 (since the annual interest rate is 4.7%), and we want to find the time t when A = $2500. Plugging these values into the formula, we get:
$2500 = $2200[tex]e^(0.047t)1.13636 = e^(0.047t)[/tex]
ln(1.13636) = 0.047t
t = ln(1.13636) / 0.047
t ≈ 7.22
Therefore, the amount in Jason's savings will exceed the cost of a new television approximately 7.22 years from now.

Use the multiplier formula to calculate the eventual change in aggregate expenditure due to this R10 billion injection. The marginal propensity to save (mps) is 0,4. Remember to show all formulas and calculations!
Using the multiplier formula, the eventual change in aggregate expenditure due to the inflow of R10 billion into South Africa and using the marginal propensity to consume (MPC) is R6 billion.
What is the multiplier formula?The multiplier formula is used to compute the amount of new income generated from the flow of extra income.
The multiplier formula uses the MPS (marginal propensity to save) to compute the multiplier as follows:
M = 1 / MPS
The marginal propensity to save gives the proportion of income that will be saved.
The marginal propensity to save (MPS) = 0.4
M = 1 / MPS
M = 1/0.4)
= 2.5
Change in aggregate expenditure = R25 billion (2.5 x R10 billion)
Thus, we expect the aggregate expenditure in South Africa to increase by R25 billion following the inflow of R10 billion investment.

intelligence test scores refered to as intelligent quotient or IQ scores are based on characteristics such as verbal skills,abstruct reasoning power, numerical ability and spatial visualization.if plotted on a graph the distribution of IQ scores approximates a normal curve with a mean of about 100. an IQ scores above 115 is considered superior studies of "intellectually gifted" children have generally defined the lower limit of their IQ scores at 140: approximately 1% of the population have IQ scores above this limit.find the standard deviation of this distribution?
The standard deviation of the distribution is given as follows:
[tex]\sigma = 17.2[/tex]
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The mean of the distribution of IQ scores is given as follows:
[tex]\mu = 100[/tex]
X = 140 is the 99th percentile, as approximately 1% of the population have IQ scores above this limit, hence when X = 140, Z = 2.327, meaning that the standard deviation is obtained as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.327 = \frac{140 - 100}{\sigma}[/tex]
[tex]2.327\sigma = 40[/tex]
[tex]\sigma = \frac{40}{2.327}[/tex]
[tex]\sigma = 17.2[/tex]

Help, please? lol its for like homework or whatev. helpppp!!
twelve cans of dog food cost $16.80. How much is one can?
Answer: 1.4
Step-by-step explanation: Just divide.
16.80 divided by 12, is 1.4(0). And if you multiply 1.4 by 12 you get 16.8(0)
Solve by factoring (15 points)
g²+4g-32=0
A 9=32 or 28
B 9=4 or 8
C 9=2 or -16
D 9=4 or -8
[tex]g^{2} +4g-32=0[/tex]
[tex]g^{2} + 8g - 4g - 32=0[/tex]
[tex]g(g+8)-4(g+8) = 0[/tex]
[tex](g+8)(g-4) = 0[/tex]
[tex]g+8=0 \implies \bf g = -8[/tex]
[tex]g-4=0 \implies \bf g = 4[/tex]
[tex]\implies g = 4 \ or \ -8[/tex]
