We can see that
There are four triangle on the surface
and five squares
For finding surface areas , we will find area of each surface and then add them
Calculation of area of triangle:
We are given
base=b=8
height=h=10
now, we can use area formula



Calculation of area of square:
base=width=8


There are four triangle and five squares on the surface
so, we can find surface area
SA=4* triangle + 5*square


so, surface area is
.............Answer
y=4^x −1
x intercept is the point when y = 0, so you sub in 0 for y:
0 = 4^x - 1
4^x = 1
Any number excluding 0 that is raised to the the exponent 0 always equals 1, 0^0 is undetermined.
x = 0
x intercept = (0,0)
If the x intercept is at the origin (0,0) than the y intercept is also (0,0)
s is the only line that passes through (0,0)
Answer:
B
Step-by-step explanation:
10 + 9 = 19
Answer:
True
Step-by-step explanation:
Simple random sampling chooses at random members of the population. This allows all members an equal probability of being selected for the sample.
