Answer:
(a) Output = 37
(b) Input = 9
Step-by-step explanation:
Given
[tex]y =x5 - 3[/tex]
Solving (a): Output, when input = 8
This means that, we solve for y when x = 8
So, we have:
[tex]y =x5 - 3[/tex]
[tex]y =8*5 - 3[/tex]
[tex]y =40 - 3[/tex]
[tex]y = 37[/tex]
Solving (b): Input, when output = 42
This means that, we solve for x when y = 42
So, we have:
[tex]y =x5 - 3[/tex]
[tex]42 = x5 - 3[/tex]
Collect like terms
[tex]x5 = 42 + 3[/tex]
[tex]x5 = 45[/tex]
Divide both sides by 5
[tex]x = 9[/tex]
What is the slope of the line that contains the
points (-6, 1) and (4,4)?
Answer:
3/10
Step-by-step explanation:
y2 - y1 / x2 - x1
4 - 1 / 4 - (-6)
3/ 10
Answer:
Step-by-step explanation:
y1-y2
--------
x1-x2
so
and (x1,y1) and (x2,y2) are those points so plug it in
(1-4)/(-6-4) so that simplifies to -3/-10 so just 3/10 is the slope.
Hope this helps!

A teacher gives a test in which the average of the test scores is 68 and the standard deviation is 14. Realizing that the test was probably too difficult, the teacher decides to scale the tests by adding 10 points to all scores. What is the mean and standard deviation of the scaled test scores?
Answer:
Mean = 78 ;
Standard deviation = 14
Step-by-step explanation:
Given that:
Mean score = 68
Standard deviation = 14
When a constant value is added to the individual value of a dataset, the new mean value will become the sum of the initial mean value and the constant term added to the values.
Constant Added score = 10
The mean of scaled test score will be:
Mean score + constant added score
68 + 10 = 78
The standard deviation remains unchanged ; Hence, standard deviation = 14
Which of the following is the converse of the statement "If it is snowing,then
it is my birthday"?
O A. If it is not my birthday, then it is snowing.
O B. If it is my birthday, then it is snowing.
C. If it is not my birthday, then it is not snowing.
D. If it is my birthday, then it is not snowing.
Answer:
B)
Step-by-step explanation:
to get the converse, interchange the hypothesis and conclusion
in this case the hypothesis is "if it is snowing" and the conclusion is "then it is my birthday"
Converse would then be "If it is my birthday, then it is snowing"
Ivan draws PQR on the coordinate plane.
What is the perimeter of PQR? Round to the
nearest unit.
Answer:
Perimeter of PQR = 37 units (Approx.)
Step-by-step explanation:
Using graph;
Coordinate of P = (-2 , -4)
Coordinate of Q = (16 , -4)
Coordinate of R = (7 , -7)
Find:
Perimeter of PQR
Computation:
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between PQ = √(-2 - 16)² + (-4 - 4)²
Distance between PQ = 18 unit
Distance between QR = √(16 - 7)² + (-4 + 7)²
Distance between QR = √81 + 9
Distance between QR = 9.48 unit (Approx.)
Distance between RP = √(7 + 2)² + (-7 + 4)²
Distance between RP = √81 + 9
Distance between RP = 9.48 unit (Approx.)
Perimeter of PQR = PQ + QR + RP
Perimeter of PQR = 18 + 9.48 + 9.48
Perimeter of PQR = 36.96
Perimeter of PQR = 37 units (Approx.)

Omar compra una bicicleta, que tiene un descuento del 75%. Si el precio que pago es de Q 70.00. ¿Cuál fue el precio original?
Answer: Por ejemplo, un televisor podría costarle originalmente $ 5000. Determine el porcentaje de descuento: en nuestra tienda de ejemplo, todo tiene un 75% de descuento. La suma que queda en su bolsillo, sus ahorros, es simplemente estos dos valores multiplicados entre sí: 75% * $ 5000 = 0,75 * $ 5000 = $ 3750.

My nephew, Oliver, got a new Lego set. He has decided to build it with his friend, Josie. It took them 6 hours to build together. If Oliver is half as fast as Josie, how long would it take Josie to build this Lego set alone?
Answer:
4 hours
Step-by-step explanation:
If it took them together with a total of 6 hours and Oliver is half as fast meaning Jose is faster it will take Jose 4 hours.
A simple equation is
6= 4+2
And the 2 would be Oliver since Oliver is half as fast.

2nd One: 27.3
Step-by-step explanation:
Both shapes- from what I can see- are right triangles. This means each shape is 90 degrees. If you subtract the given number by 90, you'll have your missing value :)

Which answer choice correctly represents an algebraic expression for the quotient of a number and 9?
A. 9j
B. j ÷ 9
C. j – 9
D. 9 + j
=========================================================
Explanation:
The quotient is the result after a division problem.
As another example, we would say that 9 is the quotient of 27 and 3 because 27 ÷ 3 = 9
We can use the slash symbol / to mean division. So we could say 27/3 = 9
Going back to the answer, we could rewrite j ÷ 9 as j/9
The order is important. This means j ÷ 9 is different from 9 ÷ j which represents "the quotient of 9 and j".

Answer:
She will need 21.3 total wire.
Answer:
21.26 ft
Step-by-step explanation:
For calculating, you need to use the Pythagorean theorem:
length of one cable = [tex]\sqrt{7^2+8^2}[/tex]= 10,63 ft
length of two cable = 10,63*2 = 21,26 ft
When you have two shapes to compare on a coordinate plane, you can determine the scale factor, knowing that the transformation was a dilation. Generate instructions you would give another student to determine the scale factor. If you know the center of dilation is the origin, you can simply divide any non-zero coordinate of the transformed figure by the corresponding coordinate of the original figure to get the scale factor. Sample Response: Locate two corresponding ordered pairs of the two shapes. Calculate how much the pre-image values were multiplied by to obtain the image values. This is your scale factor. You can calculate this by dividing the coordinates of the mage by the corresponding coordinates of the pre-image. Which did you include in your response? Check all that apply. Use corresponding ordered pairs. Divide the coordinates of the image by the pre-image. Determine that the pre-image times the scale factor produces the image.

Either your options are wrong or question is to find lateral surface.
Lateral Surface area = ( a + b + c) x H , where a, b , c are sides of the triangle.

A restaurant customer left $3.50 as a tip. The tax on the meal was 7% and the tip was 20% of the cost including tax.
Answer:
17.50
Step-by-step explanation:
you really don't need to know the tax amount.
20% of x = 3.50
(20/100) x = 3.50 Divide top and bottom of the left number by 20
(20÷20) / (100÷20) * x = 3.50
(1/5) x = 3.50 Multiply both sides by 5
x = 3.50 * 5
x = 17.50
The meal cost 17.50

Answer:
1230.88
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = (3.14) * (7)^2 * 8
V = 3.14 * 49*8
V =1230.88
