What is the surface area of the rectangular prism?200 in2


110 in2


220 in2


180 in

Answers

Answer 1
Answer:

Answer:

220 in2

Step-by-step explanation:

(10 * 5) * 2 = 100

(10 * 4) * 2 = 80

(5 * 4) * 2 = 40

cuz the bottom of the rectangle

100 + 80 + 40 = 220

The area of a circle of radius r is given by A=\pi r^2A=πr 2 and its circumference is given by C=2\pi rC=2πr. At a certain point in time, the radius of the circle is r=8r=8 inches and the area of the circle is changing at a rate of \frac{dY}{dt}=\pi\sqrt{2} dt dA ​ =π 2 ​ square inches per second. How fast is the radius of the circle changing at this time

Answers

Answer:

Step-by-step explanation:

If I'm understanding this correctly, your problem is as follows:

The area of a circle is given by the formula

A=\pi r^2

The area of the circle is changing at a rate of (dA)/(dt)=√(2)\pi.  Find the rate of change of the radius, (dr)/(dt) , when r = 8.

Assuming that is what you are asking, we will begin by finding the derivative of the area of a circle using implicit differentiation.

(dA)/(dt)=\pi2r(dr)/(dt)

Filling in what we have:

√(2)\pi=\pi(2)(8)(dr)/(dt) which simplifies a bit to

√(2)\pi=16\pi(dr)/(dt)

Divide both sides by 16π to get:

(√(2)\pi )/(16\pi)=(dr)/(dt)

The π's cancel leaving the rate of change of the radius as

(dr)/(dt)=.0883883476 inches per second

Identify all factors of the expression 12x^2-14x-6

Answers

Let's solve this by using the quadratic formula:

(-b+-√(b^2-4ac) )/(2a)


Note that we only use the coefficients so a=12, b=-14, and c=-6.

Plug values in the quadratic equation:

\frac{ -  ( - 14)± \sqrt{ {( - 14)}^(2) - 4(12)( - 6) } }{2(12)}

And so by evaluating those values we obtain:

(14+-√(484) )/(24)=(14+-22)/(24)  \n\n

Now we have two answers which are our factors one where we add another where we subtract and so:

First factor:

(14+22)/(24)=(36)/(24)=(3)/(2)


Second Factor:

(14-22)/(24)=(-8)/(24)=-(1)/(3)


And so your factors are

(3)/(2),-(1)/(3)

meaning that those are your roots/x-intercepts.

Answer: m=6.2t, 148.8 miles

Step-by-step explanation:

to figure out the equation we do 93/15=6.2 and we make it into a equation which is m=6.2t. since we know the butterfly travels 6.2 per hour we do 6.2 x 24 = 148.8

sorry if it's wrong
