Step-by-step explanation:

Here,
For the base of pyramid which is a rectangle,
length(a) = 8m
breadth(c) = 5m
For the pyramid,
actual height (h) = 6m
Now,
The formula for the Volume of a rectangular based pyramid is,
1/3 * Area of base rectangle * height
= 1/3 * (a*c) * 6 [ Because area of rectangle is product of its two sides, length and breadth]
= 2 * 8 * 5
80m^3

Traveling at 55 miles per hour, how many minutes, rounded to the nearest whole number, does it take to drive 310 miles from Bost

antoniya [11.8K]

360 minutes because to get 310 miles going 55mph it would take 6 hours at 330 miles if rounded nearest whole then you would find the amount of minutes by multiplying 6(hours) and 60(minutes for each hour)

Answer: D) reflection over the x-axis, vertical shrink by a factor of 7/8, horizontal shift 3 units to the left, and vertical shift 3 units up.

Step-by-step explanation:

$Consider\ f(x)=Ae^{Bx-C}+D\qquad where$

A = vertical stretch by a factor of A (|A| < 1 is a vertical shrink)
-A = reflection across the x-axis
B = horizontal shrink by a factor of 1/B
C = horizontal shift C units (positive = right, negative = left)
D = vertical shift D units (positive = up,, negative = down)

$f(x)=e^x\\\\g(x)=-\dfrac{7}{8}e^{x+3}+3$

→ A = -(7/8)

The negative sign represents a reflection across the x-axis.

(7/8) < 1 so it is a vertical shrink by a factor of (7/8)

→ C = -3 x +3 = x - (-3)

This is a horizontal shift 3 units to the left.

→ D = +3

This is a vertical shift 3 units up.
