Answer:
10 and -10
Step-by-step explanation:
difference of two squares:
x² - 100 = 0
(x + 10)(x - 10) = 0
x + 10 = 0; x = -10
x - 10 = 0; x = 10

3. Find the values of the constants in each of the following:
(1) f(x) = ax + b, a and b are constants, f2) = 7,f(1) = -1
9514 1404 393
Answer:
a = 8; b = -9
Step-by-step explanation:
Filling in the given values gives you two equations.
7 = a(2) +b
-1 = a(1) +b
Subtracting the second equation from the first gives ...
(7) -(-1) = (2a +b) -(a +b)
8 = a . . . . . simplify
Using this value in the first equation gives ...
7 = (8)(2) +b
b = 7 -16 = -9
The constants are a = 8, b = -9.

Answer:
[tex]C' = (2,8)[/tex]
[tex]A' = (4,4)[/tex]
[tex]T' = (10,10)[/tex]
Step-by-step explanation:
Given
[tex]k =2[/tex]
[tex]C =(1,4)[/tex]
[tex]A = (2,2)[/tex]
[tex]T =(5,5)[/tex]
Solving (a): The new points
To do this, we simply multiply the old points by the scale factor.
i.e.
[tex]New = Old * k[/tex]
So:
[tex]C' = (1,4) * 2 = (2,8)[/tex]
[tex]A' = (2,2) * 2 = (4,4)[/tex]
[tex]T' = (5,5) * 2 = (10,10)[/tex]

cube root 1331 : reciprocal of 0.2
give your answer in the form n:1
Answer:
2.2 : 1
Step-by-step explanation:
cube root 1331 : reciprocal of 0.2
give your answer in the form n:1
The cube root of 1331
(1331)^1/3 = 11
Reciprocal of 0.2 = 1 /0.2 = 5
Hence, the ratio Can be expressed as :
11 : 5
In the form n : 1
divide both sides by 5

Kaitlyn is walking on a treadmill at a constant pace for 36 minutes. She has programmed
the treadmill for a 2-mile walk. The display counts backward to show the distance
remaining.
Enter and graph the equation that gives the distance f(x) left in miles as a function of the
number x of minutes she has been walking. Then, find and compete the interpretation of
the x- and y-intercepts.
The equation is f(x) =
Answer:
x int = (36,0)
y int = (0,2)
Step-by-step explanation:
Speed = distance / time
speed = 2/36 = 0.05555 Or 1/18 (as a fraction)
equation = f(x) = 2 - x/18
graph
The equation that gives the distance f(x) left in miles as a function of the number x of minutes she has been walking is [tex]f(x) = -\frac{x}{18} + 2[/tex]
The x-intercept of the graph is at (0, 2) which shows that the distance traveled at the beginning is 2 miles
The y-intercept of the graph is at (36, 0) which shows that no distance was covered when at when the time is 36 minutes
The general equation that represents the graph is expressed as:
[tex]f(x) = 2 - sx[/tex]
s is the speed of Kaitlyn
The formula for calculating the speed is expressed as;
[tex]speed = \frac{distance}{time}[/tex]
The function required will become;
[tex]f(x) = 2 - \frac{d}{t}x\\[/tex]
Given the following parameters
distance "d" = 2 miles
Time "t" = 36 minutes
Substitute the given parameters into the function as shown:
[tex]f(x) = 2 - \frac{2}{36}x\\f(x) = 2 - \frac{1}{18}x\\f(x) = -\frac{x}{18} + 2[/tex]
Hence the equation that gives the distance f(x) left in miles as a function of the number x of minutes she has been walking is [tex]f(x) = -\frac{x}{18} + 2[/tex]
Get the y-intercept of the function:
If x = 0
[tex]f(x) = -\frac{0}{18} + 2\\f(x) = 2[/tex]
The y-intercept of the function is (0, 2)
Get the x-intercept of the function
[tex]0 = -\frac{x}{18} + 2\\-2 = -\frac{x}{18} \\x = 36[/tex]
Hence the x-intercept of the graph is expressed as (36, 0)

A fair die is rolled four times. Calculate the probability of obtaining exactly two 4s.
Answer:
The probability of getting two 4s is 5.55%.
Step-by-step explanation:
Since fair says is rolled four times, to calculate the probability of obtaining exactly two 4s the following calculations must be performed:
100/6 = 16.6666
0.166666 x 0.166666 = X
0.02777 = X
1 = 100
0.02777 = X
0.02777 x 100 = X
2.77 = X
2.77 x 2 = 5.55
Therefore, the probability of getting two 4s is 5.55%.
