a) (2.3 × [tex]$10^4[/tex]) × (1.5 × [tex]$10^{-2}[/tex]) in standard form
The number in standard form is 345
explanation:
The given two multiplication of the numbers is :
(2.3 × [tex]$10^4[/tex]) × (1.5 × [tex]$10^{-2}[/tex])
First we multiply the non exponential terms as shown below
2.3 × 1.5 = 3.45
Now we multiply the exponential terms as shown below
[tex]$10^4[/tex] × [tex]$10^{-2}[/tex] = 100
Now multiplying the exponential and non exponential term we get the number in standard form as shown below
(2.3 × [tex]$10^4[/tex]) × (1.5 × [tex]$10^{-2}[/tex]) in standard form 345
(3.6 × [tex]10^-5[/tex])÷(1.8 × 10²) in standard form 0.0000002
(8 × 10^-3) × (2 × [tex]10^-4[/tex] in standard form 1.6 × [tex]10^-6[/tex]
(6 × 10²)/(3 × 10-5) in standard form 20,00,0000
5.1 × [tex]$10^-1[/tex] in ordinary number is 0.51
(1.7 × [tex]10^4[/tex]) × (8.5x ×[tex]0^-2[/tex]) in standard form 1.445 × 10³.
3.45 x 100 = 345
Therefore, the number in the standard form is 345
b) (3.6 × [tex]10^-5[/tex])÷(1.8 × 10²) in standard form
The number in standard form is 0.0000002
explanation:
By dividing 3.6 by 1.8 we get “2”, hence the above equation becomes,
(2 × [tex]10^-5[/tex]) /[tex]10^2[/tex]
We know that
[tex]\frac{x^{a} }{x^{b} } = x^{a-b}[/tex]
Therefore the above equation becomes,
2 × [tex]10^-7[/tex]
since the exponent of 10 is negative , therefore 7 zeros are written on the left hand side of the number = 0.0000002
Therefore, the number in the standard form is 0.0000002
c) (8 × [tex]10^-3[/tex]) × (2 × [tex]10^-4[/tex]) in standard form
The number in standard form is 1.6 × [tex]10^-6[/tex]
explanation:
Given the product of scientific notations:
(8 × [tex]10^-3[/tex]) × (2 × [tex]10^-4[/tex])
This can be expressed as:
(8 × 2) × ([tex]10^-3[/tex] × [tex]10^-4[/tex])
= 16 × [tex]10^-3[/tex]-4
= 16 × [tex]10^-7[/tex]
= 1.6 × [tex]10^1[/tex] × [tex]10^-7[/tex]
= 1.6 × [tex]10^-6[/tex]
Therefore, the number in the standard form is 1.6 × [tex]10^-6[/tex]
d) (6 × 10²)/(3 × 10-5) in standard form
The number in standard form is 20,00,0000
e) 5.1 × 10^-1 as an ordinary number
The ordinary number is 0.51
usual form of 5.1 × [tex]10^1[/tex] is
5.1 × 1/ [tex]10^1[/tex]
= 5.1/10
= 0.51
Therefore , ordinary number is 0.51
f) (1.7 × [tex]10^4[/tex]) × (8.5 × [tex]10^-2[/tex]) in standard form.

The function f(x) is shown on the graph.
The graph shows a downward opening parabola with a vertex at negative 3 comma 16, a point at negative 7 comma 0, a point at 1 comma 0, a point at negative 6 comma 7, and a point at 0 comma 7.
What is the standard form of the equation of f(x)?
f(x) = −x2 − 6x + 7
f(x) = −x2 + 6x + 7
f(x) = x2 − 6x + 7
f(x) = x2 + 6x + 7
Answer:
f(x)= -x^2-6x+7
Step-by-step explanation:
Since the graph opens downward the function for the parabola is going to be negative. This leaves us with two answers.
Now use the remaining possible equations and solve for the vertex.
Using x= -b/2a to solve for the x value of the vertex plug in the values to solve.
a= -1 b= -6 c=7 so, since -6 is already negative plugging it in makes it positive -(-6)/2(-1) = 6/-2 = -3. So x equals negative 3.
Then plug in -3 into the equation to get the y-value.
- (-3)^2 - 6(-3) + 7 = -9 + 18 + 7 = 16 so this confirms the vertex for this equation is (-3,16) so the answer is -x^2-6x+7.

scores on an iq test are normally distributed. the test is designed so that the mean is 100 and standard deviation is 15. hat is the cutoff score so that only 5% of the population has a higher score?
The cutoff score so that only 5% of the population has a higher score is 124.7.
If 5% of the population has a higher score, then the probability of selecting these is 0.05.
Find the z-score that corresponds to the probability in the z-table. (see attached images)
probability = 1 - 0.05 = 0.95
z-score = 1.647
Using the formula for the z-score below, determine the cutoff score.
z-score = (x – μ) / σ
where x = individual data value = cutoff score
μ = mean = 100
σ = standard deviation = 15
1.647 = (x - 100) / 15
1.647(15) = x - 100
x = 24.705 + 100
x = 124.705
cutoff score = 125

The required equation of line would be 2y = 5x - 8 which is shown in the given graph.
What is the slope of the line?The slope of a line is defined as the angle of the line.
According to the given figure,
We clearly see that the coordinates of the y-intercept would be (0, -4).
The value of the x-coordinate is 2 when y-coordinate is 1.
Here the line passes through the points (0, -4) and (2, 1).
Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x₂ -x]
x₁ = 0, y₁ = -4
x₂ = 2, y₂ = 1
⇒ y - y₂ = (y₂ - y₁)/(x₂ -x₁ )[x -x₂]
⇒ y - 1 = (1 - (-4))/(2 - 0 )[x -2]
⇒ y - 1 = 5/2[x -2]
⇒ 2y - 2 = 5[x -2]
⇒ 2y = 5x - 10 + 2
⇒ 2y = 5x - 8
Therefore, the required equation of line would be 2y = 5x - 8 which is shown in the given graph.

Aaron has to pay $ 115 when the usage gets over by 3 GBs and
$ (40 + 25x) when the usage gets over by x GBs.
How can one calculate the cost for a multiple of the same entity?
To calculate the cost of a multiple entities when the cost of a single one is given, we linearly multiply a fixed proportion to it to calculate the same.
Given, monthly fixed cost of the smart phone data plan = $ 40
Also, amount charged by the firm for each extra GB used = $ 25
Now, amount charged for three extra GBs = 25*3 = 75
Thus, net total that Aaron has to pay for 9 GBs = 40 + 75 = $ 115
Following similar arguments, amount charged for extra 'x' GBs = 25x
Thus, net total that Aaron has to pay for x GBs = 40 + 25x = $ (40 + 25x)
Therefore, Aaron has to pay $ 115 when the usage gets over by 3 GBs and $ (40 + 25x) when the usage gets over by x GBs.

If the interest earned on an account after 2 years is 15$ how much would it be after 10 years? why?
The amount of interest earned in 10 years is $75.
What is interest?Interest is the sum over and above the original amount (the amount borrowed) that is paid to a lender or depositor by a borrower or deposit-taking financial institution at a set rate. It is not the same as a fee that the borrower might pay to the lender or another entity.It also differs from a dividend, which is money given to shareholders (owners) by a company from its profit or reserve but not at a set rate predetermined in advance, but rather on a pro-rata basis as a share of the reward received by risk-taking business people when revenue is earned that exceeds all costs.So, interest earned after 2 years = $15
interest earned in 1 year = 15/2 = $7.5 interest earned in 10 years = 10 × $7.5= $ 75Therefore, the amount of interest earned in 10 years is $75.

Taking into account the definition of a system of linear equations, the first number is x= -14 and the second number y= -13.
System of linear equationsA system of linear equations is a set of linear equations (that is, a system of equations in which each equation is of the first degree) in which two or more unknowns are related.
Systems of linear equations have as a solution set all ordered pairs (x, y) that satisfy the equation, where x and y are real numbers. That is, solving a system of equations consists of finding the values of the unknowns, with which, when replaced in the equations, they must give the proposed solution.
This caseIn this case, a system of linear equations must be proposed taking into account that
"x" is the first number."y" is the second number.You know:
The difference between the two numbers is -1. Their sum is -27.The system of equations to be solved is
x-y= -1
x+y= -27
It is decided to solve the system of equations using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable "x" from the first equation:
x= -1 +y
Replacing this expression in the second equation:
-1 +y +y= -27
Solving:
y +y= -27 +1
2y= -26
y= (-26)÷2
y= -13
Remembering that x=-1 +y, you get
x= -1 -13
x= -14

Write the total cost C as a function of the number of CD's produced.C=$___Write the total revenue R as a function of the number of CD's produced R=$_______Write the total profit P as a function of the number of CD's producedP=$______Find the number of CD's which must be produced to break even.The number of CD's which must be produced to break even is_______
Remember that to model this kind of problems, we can use the equation of a straight line
[tex]y=mx+b[/tex]Where:
• b, are the fixed costs
,• x ,represents what varies
,• m, is the cost of what varies
1. Therefore, using the data provided, we can model the cost of production with a function where:
• x ,is the numbers of CD's produced
,• C, is the cost of producing those CD's
[tex]C=8x+30000[/tex]2. To model the revenue, we'll have to take into account that every CD sells at $68. Therefore, the money collected by selling the x CD's produced is:
[tex]R=63x[/tex]Where:
• x ,its the number of CD's produced and sold
,• R, is the total revenue
3. To get the profit, we'll have to substract the production cost to the money collected by the sale. Remember we already have two expressions, in terms of x, that describe both situations. Therefore,
[tex]\begin{gathered} P=R-C \\ \rightarrow P=63x-(8x+30000)\rightarrow P=63x-8x-30000 \\ \rightarrow P=55x-30000 \end{gathered}[/tex]Where:
• x ,its the number of CD's produced and sold
,• P, is the total revenue
4. In order to break even, the revenue (R) has to be equal to the cost of production (C), Thus,
[tex]\begin{gathered} R=C\rightarrow63x=8x+30000 \\ \rightarrow63x-8x=30000 \\ \rightarrow55x=30000\rightarrow x=\frac{30000}{55} \\ x=545.5 \\ \text{Rounding to closest integer,} \\ x=546 \end{gathered}[/tex]Therefore, 546 CD's would have to be produced to break even.
a water tank is to contain 2,000 liters of water it is constructed to be 4 meters long and 1.5 meters wide. find the height of the tank.
Remember that
1 m3=1,000 lt
2 m3=2,000 lt
The volume of the tank is equal to
V=L*W*H
we have
V=2 m3
L=4 m
W=1.5 m
H=?
substitute given values
2=4*1.5*H
solve for H
2=6H
H=2/6
