Let us name the figures from left to right as Figures 1,
2, 3, and 4.
Figure 1: Cylinder
The formula for surface area of cylinder is:
SA = 2 π r h
where r = 5 cm and h = 10 cm
SA = 2 π (5 cm) (10 cm)
SA = 100 π cm^2 = 314.16 cm^2
Figure 2: Triangular prism
SA = (a + b + c) h
where a, b, c are the sides of the triangle and h is the
length of the prism
a = 4 m
b = c = 2.5 m
h = 6 m
SA = (4 m + 2.5 m + 2.5 m) 6 m
SA = 54 m^2
Figure 3: Rectangular prism
SA = 2lw + 2wh + 2lh
where l, w and h are the sides
l = 3.5 ft
w = 2.4 ft
h = 5.2 ft
SA = 2 (3.5*2.4 + 2.4*5.2 + 3.5*5.2)
SA = 78.16 ft^2
Figure 4: Rectangular prism
SA = 2lw + 2wh + 2lh
where l, w and h are the sides
l = 6 ft
w = 4.5 ft
h =12 ft
SA = 2 (6*4.5 + 4.5*12 + 6*12)
SA = 306 ft^2
Answer:
Step-by-step explanation:
y = f(x)
y = 6 * 3^x
Interchange x and y
x = 6 * 3^y
Divide by 6
x/6 = 3^y
Take the log of both sides
log(x/6) = log(3)^y
Bring the y down
log(x/6) = y log(3) \
Divide by log(3)
log(x/6)/log(3) = y
Let x = 2
log(2/6) / log(3) = y
-(0.4771 )/ 0.4771 = y
y = - 1
Remark
The original graph is in green
The red graph is the inverse.
The point (2,-1) is marked so that you know it falls on the inverse.
Answer:
This is a ratio problem
Since we know 4.75 inches equals 75 miles, we can find what small unit of a inch correlates to 75 miles, and then use that data to find the other answer. To do this, we divide 75 miles by 4.75 inches. We get 16 as an estimate (15.789 to 16). Knowing this, we can multiply 16 to 6.25 and get 100 miles. 100 miles is the answer
