Which equation is true when x=10 but not when x= – 10? Select all that apply.
Answers
Applying power rules, the equations that is true when x = 10 but false when x = -10 is given as follows:
x³ = 10000.
Exponents of 10The behavior of the exponents of 10 is different for even and for odd exponents, as follows:
Even exponents generate even functions, that is, 10^n = (-10)^n if the exponent n is even.Odd exponents generate odd functions, that is 10^n = -(-10)^n if the exponent is odd.In this problem, we have two exponents, as follows:
Exponent 2 is even.Exponent 3 is odd.We want different results for the power when x = 10 and when x = -10, hence the correct option will involve the odd exponent 3.
The third power of 10 is calculated as follows:
10³ = 10 x 10 x 10 = 100 x 10 = 1000.
Hence the equation that is true for x = 10 and false for x = -10 is:
x³ = 10000.
As when x = -10, the result is:
(-10)³ = (-10) x (-10) x (-10) = 100 x (-10) = -1000.

(a) Find the z score corresponding to
x = 27.
(b) Find the z score corresponding to
x = 43.
(c) Find the raw score corresponding to
z = −3.
(d) Find the raw score corresponding to

Answers
a) z score corresponding to x = 27 is -1
b) z score corresponding to x = 43 is 2.2
c) Raw score corresponding to z = -3 is 17.
d) Raw score corresponding to z = 1.1 is 37.5
Given,
Normal distribution with μ = 32 and σ = 5
a) z score corresponding to x = 27
z = (x - μ) / σ
Then,
z = (27 - 32) / 5 = -5/5 = -1
That is, z score corresponding to x = 27 is -1.
b) z score corresponding to x = 43
z = (x - μ) / σ
Then,
z = (43 - 32) / 5 = 11/5 = 2.2
That is, z score corresponding to x = 43 is 2.2
c) Raw score corresponding to z = -3
z = (x - μ) / σ
Then,
-3 = (x - 32) / 5
-3 × 5 = x - 32
-15 = x - 32
x = 32 - 15 = 17
That is, raw score corresponding to z = -3 is 17.
d) Raw score corresponding to z = 1.1
z = (x - μ) / σ
1.1 = (x - 32) / 5
1.1 × 5 = x - 32
x = 32 + 5.5 = 37.5
That is, raw score corresponding to z = 1.1 is 37.5

Answers
His friend's house is 1.2 miles away from his house.
How do you know his friend's house is 1.2 miles away from his house?Well, the solution to this math problem is very simple. We just need to remove a number away from another. In other words, we only need to do some subtraction.
Subtraction is one of four main arithmetic operations in which we use to take away a number or an amount from another number or amount. Remember that the commutative law doesn't apply to subtraction, so we really need to be careful to pick what number is subtracted by the other number.
The distance from Greg's house to the store is 8.9 miles away. That's the number that is going to be subtracted. His friend's house is 7.7 miles away from the store. This is the number that we're going to subtract from the previous number. Mathematically, we can express this as:
8.9 - 7.7 = 1.2
We're left with 1.2, which is the distance in miles from Greg's house to his friend's house.

Explanation
[tex]f(x)=x^4[/tex]Step 1
the first transformation is the function multiplied by a constant ( 1/2)
If the function is multiplied by a value less than one, all the values of the equation will decrease, leading to a “shrunken” appearance in the vertical direction
so

Step 2
the second transformation is add 5
[tex]f(x)=x^4\Rightarrow\frac{1}{2}x^4\Rightarrow g(x)=\frac{1}{2}x^4+5[/tex]If a positive number is added, the function shifts up the y-axis by the amount added.

Step-by-step explanation:
When given an equation like this, remember the formula y=mx+b that you should have learned. This formula is the slope-intercept formula that you can use. The m is the slope and the b is the intercept. In the equation, the x is what we are trying to find.
y=-2/3x+3
y=mx+b
m=-2/3
b= (0,3)
So, graph the slope as -2/3 and the y-intercept as (0,3).

containing no bluegrass seed (0%) should be added to the seed mixture for a resulting
blend that is 20% bluegrass seed? Construct a table, then solve.
Answers
Step-by-step explanation:
what table is your teacher taking about ?
in any case this is resistive easy to solve
80 pounds of 30% with x pounds of 0% result in 80+x pounds of 20% :
80×0.3 + x×0 = (80 + x)×0.2 = 80×0.2 + x×0.2
80×0.1 = x×0.2
x = 80×0.1/0.2 = 80/2 = 40 pounds
so, 40 pounds of 0% have to be added to the 80 pounds of 30% to get a mixture of 20% (80+40 = 120 pounds).

Given the base and height pairs in the question.
Let us use the corresponding pairs that gives the same area.
Firstly, for the first pair;
[tex]\begin{gathered} A=\frac{1}{2}\times10\times3.5=17.5cm^2 \\ A=\frac{1}{2}\times10\times7=35cm^2 \\ A=\frac{1}{2}\times10\times2.5=12.5cm^2 \end{gathered}[/tex]Secondly, the second pair is;
[tex]\begin{gathered} A=\frac{1}{2}\times5\times7=17.5cm^2 \\ A=\frac{1}{2}\times5\times3.5=8.75cm^2 \\ A=\frac{1}{2}\times5\times2.5=6.25cm^2 \end{gathered}[/tex]Thirdly, the third pair;
[tex]\begin{gathered} A=\frac{1}{2}\times14\times3.5=24.5cm^2 \\ A=\frac{1}{2}\times14\times7=49cm^2 \\ A=\frac{1}{2}\times14\times2.5=17.5cm^2 \end{gathered}[/tex]Therefore, the three correct corresponding pairs that gives the same area are;
[tex]\begin{gathered} A=\frac{1}{2}\times10\times3.5=17.5cm^2 \\ A=\frac{1}{2}\times5\times7=17.5cm^2 \\ A=\frac{1}{2}\times14\times2.5=17.5cm^2 \end{gathered}[/tex]The areas are the same in each case because the product of each pair is the same.

Whats the Point-Slope Equation for the line that goes through
(-3, 5) and (-7, 4)
Answers
Step by step
The point slope formula is y − y1 = m (x − x1 )
First we need to find “m” or slope
Slope formula is (y2 - y1) over (x2 - x1)
4-5 over -7 - -3
-1 over -4 or 1/4
Now for point slope formula using (-3, 5)
y - 5 = 1/4 (x + 3) (x - -3 is same as x + 3)
Distribute
y -5 = 1/4x + 3/4
add 5 to both sides to solve for y
y -5 +5 = 1/4x + 3/4 + 5

Triangle ABC is shown below, with the angle measures as marked.
What is the measure of Angle A and B?
Answers
The measure of Angle A and Angle B are 54° and 122° respectively.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In triangle ABC,
The measure of angle A = (n + 20)°
The measure of angle B = (3n - 10)°
The measure of angle C = n°
Now,
The sum of all the angles of the triangle = 180°
So, we can formulate;
(n + 20)° + (3n - 10)° + n° = 180°
Solve for n as;
n + 20 + 3n - 10 + n = 180
5n + 10 = 180
5n = 180 - 10
5n = 170
Divide by 5, we get;
n = 170/5
n = 34
Thus, The measure of angle A = (n + 20)°
= 34 + 20
= 54°
And, The measure of angle B = (3n - 10)°
= 3 x 34 + 20
= 102 + 20
= 122°
Therefore,
The measure of Angle A and Angle B are 54° and 122° respectively.

The sum of 4 consecutive integers is 170. What is the largest number in the group?
Answers
The largest number when the sum of 4 consecutive integers is 170 will be 44.
According to the question,
We have the following information:
Sum of four consecutive integers = 170
Now, let's take the first integer to be x.
So, the next 3 integers will be (x+1), (x+2) and (x+3) respectively.
Now, the largest number will be (x+3).
Adding 4 consecutive integers:
x+ (x+1) + (x+2) + (x+3) = 170
4x+6 = 170
4x = 170-6 (Moving 6 from the left hand side to the right hand will result in the change of the sign from plus to minus.)
4x = 164
x = 164/4
x = 41
So, the next three consecutive integers will be 42, 43 and 44.
Hence, the largest of the four consecutive integers is 44.

2. What is the equation of a line that passes through the points (-0.92, 2.49) and (-5.62, 9.76)? Write your answer in point-slope form.
Answers
Answer:
Step-by-step explanation:
-0.92 2.49
-5.62 9.76
Rise = 9.76 - 2,49 = 7.27
Run: -5.62 - (-0.92) = -4.7
Slope (Rise/Run) = (7.27.`-0.92) = -1.55
The line has the form:
y = 1.55x + b
We need to find a value of b that forces the line through both point, Use one of the points and solve for b. I'll use (-0.92, 2.49).
y = 1.55x + b
2.49 = 1.55(-0.92) + b
b = 2.49 - 1.426 = 1.064
The equation is y = 1.55x + 1.0

Frank has $66.50 in his account as of Sunday.
He made a debit of $60.33 on Monday (66.50 - 60.33), leaving him with a balance of $6.17. He added $80.75 to the account on that same Monday (6.17 plus 80.75). He has $86.92 left over as of Monday.
Frank had a balance of $86.92 on Tuesday when he made a $54.45 debit (86.92 - 54.45). The remaining balance is $32.47.
Frank had a balance of $32.47 at the beginning of the day on Wednesday. He subsequently made withdraw of $49.20. debit(32.47 - 49.20). Frank has overdrawn and will be assessed an overdraft fee following the debit because his balance is -$16.73. Frank still has a negative balance even after making a deposit of $15.
