Answer:
X=0
Step-by-step explanation:
Anything raised to the power of 0 is 1.
The line y = x and y = -x + 4 intersect when at the point (2, 2).
Expresing y = -x + 4 in terms of x, we have x = 4 - y.
Thus, the area of the region bounded by the <span>graphs of y = x, y = −x + 4, and y = 0 is given by
![\int\limits^2_0 {(y-(4-y))} \, dy = \int\limits^2_0 {(y-4+y)} \, dy \\ \\ = \int\limits^2_0 {(2y-4)} \, dy= \left[y^2-4y\right]_0^2 =|(2)^2-4(2)| \\ \\ =|4-8|=|-4|=4](https://tex.z-dn.net/?f=%20%5Cint%5Climits%5E2_0%20%7B%28y-%284-y%29%29%7D%20%5C%2C%20dy%20%3D%20%5Cint%5Climits%5E2_0%20%7B%28y-4%2By%29%7D%20%5C%2C%20dy%20%5C%5C%20%20%5C%5C%20%3D%20%5Cint%5Climits%5E2_0%20%7B%282y-4%29%7D%20%5C%2C%20dy%3D%20%5Cleft%5By%5E2-4y%5Cright%5D_0%5E2%20%3D%7C%282%29%5E2-4%282%29%7C%20%5C%5C%20%20%5C%5C%20%3D%7C4-8%7C%3D%7C-4%7C%3D4)
Therefore, the area bounded by the lines is 4 square units.

Answer:
a) 1/2
Step-by-step explanation:
All we have to do is simply find the probability of selecting a triangle, find the probability of selecting a circle and then add them together.
There are a total of 10 shapes in the box.
There are 3 triangles, so, the probability of picking a triangle is:
3/10
There are 2 circles, so, the probability of selecting a circle is:
2/10
Adding them together yields:
3/10 + 2/10 = 5/10 = 1/2
The probability of selecting a triangle or circle is 1/2.
.167 every 1 per cenimeters
25X4=100
4X_=88
88÷4=22
So she got 22 problems correct.
