Answer:
Y=-3(4)^x
Step-by-step explanation:
this is the parent function because the line goes up north and decreases so the answer will be a negative
Answer:
Each triangle weighs 3 grams.
Step-by-step explanation:
On the left side, there are 6 squares (12 grams) 3 circles (9 more grams), and 2 triangles (2x grams).
On the right side, there are 3 squares (6 grams) 2 circles (6 grams), and 5 triangles (5x grams).
This makes the equation 21 + 2x = 12 + 5x.
Let's find x.
21 + 2x = 12 + 5x
Subtract 5x from both sides.
21 - 3x = 12
subtract 21 from both sides.
-3x = -9
Divide by -3.
x = 3.
Each triangle weighs 3 grams. Let's prove this.
21 + 2x = 12 + 5x
21 + 2(3) = 12 + 5(3)
21 + 6 = 12 + 15
27 = 27

Answer:
Height is 8.0in
Step-by-step explanation:
Surface Area of a cylinder = 2πr(r+h)
r is the radius
h is the height of the cylinder
Given surface area = 408.41in²
radius = 5in
h = ?
Substituting the given value into the formula
408.41 = 2π(5)(5+h)
408.41 = 50π + 10πh
408.41 = 50(3.14)+10(3.14)h
408.41 = 157+31.4h
408.41-157 = 31.4h
251.41 = 31.4h
h = 251.41/31.4
h = 8.0in
