Answer:

The answer is C.

Step-by-step explanation:

As you can see, It won't be a square because the bottom is 4 units long and the triangle is an estimated 3 units tall, so you can cross those two answers out. Next, you can look at the first answer. What is obvious, the triangle is definitely not double a rectangle what has the same basic measurements as the triangle. Answer C is the only one that is logical.

Find the solution of the given initial value problem. ty' + 6y = t2 − t + 1, y(1) = 1 6 , t > 0

gtnhenbr [62]

Answer:

Step-by-step explanation:

Given is a differential equation as

$ty' + 6y = t^2 - t + 1, y(1) = 1 6 , t > 0$

Divide this by t to get in linear form

$y'+6y/t = t-1+1/t$

This is of the form

y' +p(t) y = Q(t)

where p(t) = 1/t $e^(\int 1/tdt) = t$

So solution would be

$yt = \int t^2-t+1 dt\\= t^3/3-t^2/2+t+C$

siubstitute y(1) = 16

$16 = 16^3/3-128+1+C\\C = -1206$

Answer: 952 ft squared

Step-by-step explanation:

Surface area, is just the area of all the faces added together.

So, the sides we need to find are measuring:

Triangle side: 10 x 8

Triangle Face; 10 x 8

Square Face: 10 x 10

Rectangular Face: 14 x 10

Bottom Rectangular face: 14 x 10

Side of the Triangular prism: 9 x 14

Because the triangle face has two of them, we only have to do one as opposed to dividing the same face twice.

So, we have a side of 80.

From here, it is just multiplication.

80 + 100 + 100 + 140 + 140 + 140 + 126 + 126 = 952 ft
