Your answer is 24sq. units.
what I did to find this answer is I got out some graphing paper, and graphed it ( I haven't been taught any other way) and then I connected the lines to make the shape. then I found the area of the invisible rectangle that was formed around it, and divided it by two... because the shape ABCD is half of the area of the rectangle formed. ... I hope you get what I'm trying to say.

If a body moves in a straight line according to the law s = 24t + 3t2 - t3 , where s is the distance measured in meters from the

Aneli [31]

Remember that the velocity as a function of time is the derivative of the position as a function of time.
To solve this we are going to take the derivative of our position function $s=24t+3t^2-t^3$ . To do that er are going to apply the power rule of calculus: $\frac{dy}{dx} x^n=nx^{n-1}$

$\frac{dy}{dx} 24t+\frac{dy}{dx}3t^2-\frac{dy}{dx}t^3$
$24+2(3)t-3t^2$
$v=24+6t-3t^2$

We can conclude that the correct answer is: B. V = 24 + 6t - 3t2

Which statements apply to the expression

bagirrra123 [75]

Answer:

A, C, D, F

Step-by-step explanation:

Given the expression : (3/5)³

Recall :

a^b where, a = base ; b = exponent

In ; (3/5)^3

Base = 3/5 ; exponent = 3

Similarly ;

a^b = a in b places

(3/5)^3 = (3/5) * (3/5) * (3/5)

(3/5) * (3/5) * (3/5) = (3*3*3) / (5*5*5) = 27/125

Hence, A, C, D and F are all correct

The length of each side of a regular pentagon is increased by 8 inches, so the perimeter is now 65 inches. What is the original

evablogger [386]

Here as the Pentagon is regular so it's all sides will be of equal length . And if we assume It's each side be s , then it's perimeter is going to be (s+s+s+s+s) = 5s.And as here , each side is increased by 8 inches and then it's perimeter is 65 inches , so we got that it's side after increament is (s+8) inches and original length is s inches . And if it's each side is (s+8) inches , so it's perimeter will be 5(s+8) and as it's equal to 65 inches . So , 5(s+8) = 65
