Answer:
55 meters squared
Step-by-step explanation:
SA = sum of all the areas of the sides
The pyramid has four faces, which we have to add together:
SA = 3(long face area) + base area
Area of a triangle = 1/2 base * height
Area of the base = 1/2 * 3.5 * 4 = 7 meters squared
Area of a long face = 1/2 * 8 * 4 = 16 meters squared
Coming back to our surface area formula, we can plug those areas in:
SA = 3(long face area) + base area
= 3(16) + 7 = <u>55 meters squared</u>
Answer:
Step-by-step explanation:
Replace g(x) with y, then switch the x and y variables:
Solve for the new y value, multiply by 2:
Subtract 5 on both sides:
Divide by -5 on both sides:
Distribute the negative sign and rearrange:
Answer:
a
Step-by-step explanation:
Answer:
Choice D
y = 3(2/3)^x
Step-by-step explanation:
a) y = 2(3/2)^x = 3^x (pretty close)
b) y = (2/3)^x (wrong, coming from the wrong side)
c) y = 2(3)^x = 6^x (too close to y line)
d) y = 3(2/3)^x = 2^x (looks right)
