Answer:
x = 79 y = 22
Step-by-step explanation:
x would be the same as the other side so 79 * 2 would be 158. A whole triangle is 180. 180 - 158 = 22
Answer:
At (-2,0) gradient is -4 ; At (2,0) gradient is 4
Step-by-step explanation:
For this problem, we simply need to take the derivative of the function and evaluate when y = 0 (when crossing the x-axis).
y = x^2 - 4
y' = 2x
The function y = x^2 - 4 cross the x-axis when:
y = x^2 - 4
0 = x^2 - 4
4 = x^2
2 +/- = x
Hence, this curve crosses the x-axis twice, once at (-2,0) and again at (2,0).
The gradient at these points are as follows:
y' = 2(-2) = -4
y' = 2(2) = 4
Cheers.
Answer:
20 * 4 = 80
Step-by-step explanation:
the answer is 80 cuz you have to multiply 20 ( the square) by 4 ( the number of sides) and you get 80
