Answer:
-7
Step-by-step explanation:
Refer to the photo.
the slope=(0-g)/(5-4)
i.e. 7=(-g)/1
g=-7
Since they share the same angle measurement, and 4 is smaller than 158 degrees, you subtract 158 from 180 and angle 4 = 22 degrees
For # 1, the answer will be 1 because of the exponential rule

.
#2, the answer is going to be

because of the exponential rule

.
#3. I'm not sure that this could be simplified any further.
#4 To get the answer to this question, we must apply the distributive property, along with the exponential rule
. When we apply these properties, we'll get

For the other questions, they all apply the Laws of Exponents.
Answer:
25π units^2
Step-by-step explanation:
The shape is a quarter circle with radius 10 units.
area of circle = πr^2
area of a quarter circle = (1/4)π(10 units)^2
area = 25π units^2
