Find the area of each figure. Round to the nearest hundredth where necessary.
leonid [27]

Answer:

A = 1,307 cm^2

Step-by-step explanation:

Formula of Surface Area of a Rectangle:

A = 2 (lw + lh + wh)

length*width = (20)(23) = 460

length*height = (23)(4.5) = 103.5

width*height = (20)(4.5) = 90

A = 2 (460 + 103.5 + 90)

A = 2(653.5)

A = 1,307 cm^2

Given the parametric equations, x = 2t + 5 and y = 3t^2 - 1, find the point on the graph at time, t = 4.
Tpy6a [65]

Answer: (13, 47)

The expression t = 4 means that 4 units of time have come off the clock (possibly 4 seconds). Plug this value into each equation given for x and y

x = 2*t + 5 = 2*4 + 5 = 8 + 5 = 13

y = 3*t^2 - 1 = 3*4^2 - 1 = 3*16 - 1 = 48 - 1 = 47

In short, if t = 4 then it leads to x = 13 and y = 47 at the same time. These x and y values pair up to get the final answer (13,47)

Jackrabbits are capable of reaching speeds up to 40 miles per hour. How fast is this in feet per second? (Round to the nearest w
Ksivusya [100]

we know that

1\ mile=5,280\ feet

1\ hour=3,600\ sec

1) <u>convert miles per hour to feet per hour</u>

40\ miles/hour=40*5,280=211,200\ feet/hour

<u>2) convert feet per hour to feet per second</u>

211,200\ feet/hour=211,200/3,600=58.67 feet/sec

Round to the nearest whole number-------> 59 feet/sec

therefore

<u>the answer is</u>

59 feet/sec
