How would you solve for x and y?

Since all of the sides are 15, and there's a right angle, we can assume the triangles are both the same size. So we can halve 15 to get the length of y, which would be 7.5. And here we can use the Pythagorean's Theorem to solve for x, by changing it to c^2-b^2=a^2, and we can fill out 15^2 - 7.5^2 = a^2, or 225 - 56.25 = √173.75, which is about 13.18.

Values of the composite function:

(g\cdot f)(-1)=6

(g\cdot f)(0)=7

(f\cdot g)(-1)=3

(f\cdot g)(4)=2

Step-by-step explanation:

Given two functions f(x) and g(x), their composite function is given by

(f\cdot g)(x) = f(g(x))

Which means using the output value of g(x) as input for f(x).

Let's start by computing

(g\cdot f)(-1)

First, we compute the value of f(-1), which is (from the graph)

f(-1) = 1

Now we use this value as input into g(x); we notice that at x = 1, the value of g(x) is 6, therefore:

(g\cdot f)(-1)=6

Now we evaluate

(g\cdot f)(0)

First, we compute the value of f(0), which is (from the graph)

f(0) = 0

Now we use this value as input into g(x); at x = 0, the value of g(x) is 7, therefore:

(g\cdot f)(0)=7

Now we evaluate

(f\cdot g)(-1)

First, we compute the value of g(-1), which is (from the graph)

g(-1) = 5

Now we use this value as input into f(x); at x = 5, the value of f(x) is 3, therefore:

(f\cdot g)(-1)=3

Finally we evaluate

(f\cdot g)(4)

First, we compute the value of g(4), which is (from the graph)

g(4) = 4

Now we use this value as input into f(x); at x = 4, the value of f(x) is 2, therefore:

(f\cdot g)(4)=2

Can someone please help me on this question! Thank you very much!!

First find the area of the triangle (on top) and then subtract the area of the circle (on bottom) since the triangle is Equilateral, you can assume that the height can be found by using the 30 60 90 angle relationship. To find the radius of the circle, divide the height by 2.

3. x = 14 degrees

4. x = 17.5 degrees

Step-by-step explanation:

SO, The first question:

6x - 21 = 105

6x = 105 -21

6x = 84

x = 14

SO, The second question:

55 + 85 = 8x

140 = 8x

17.5 = x
