SOMEONE PLEASE JUST ANSWER THIS FOR BRAINLIEST!!’

ad-work [718]

Factoring this expression using the identity of a²-b² = (a+b)(a-b)

Given :-

25 - x²

This can be broken down into:-

... ( 5 )² - ( x )²

In this case, a is 5 and b is x

... ( 5 + x ) ( 5 - x ) Is the answer.

Hope it helps!!

The bases of the prism below are right triangles. The volume of the prism is 3360 units33 . Find the height of the prism.

lana66690 [7]

Answer:

Explanation:

Given:

Volume of the prism = 3360 units^3

To find:

The height of the prism

We'll use the below formula to determine the height(h) of the prism;

$\begin{gathered} Volume(V)=Area(A)\text{ of the triangular base * Height\lparen H\rparen of the prism} \\ V=(\frac{b*h}{2})*H \\ 3360=(\frac{16*30}{2})*H \\ 3360=240*H \\ H=\frac{3360}{240} \\ H=14 \end{gathered}$

So the height of the prism is 14

CALCULUS EXPERT WANTED. Can someone solve this or at least try to explain to me the fundamental theorem of calculus (FTC).

Amanda [17]

a. By the FTC,

$\displaystyle\frac{\mathrm d}{\mathrm dx}\int_1^{\cos x}(t+\sqrt t)\,\mathrm dt=(\cos x+\sqrt{\cos x})\dfrac{\mathrm d}{\mathrm dx}\cos x=-\sin x(\cos x+\sqrt{\cos x})$

b. We can either evaluate the integral directly, or take the integral of the previous result. With the first method, we get

$\displaystyle\int_1^{\cos x}(t+\sqrt t)\,\mathrm dt=\dfrac{t^2}2+\dfrac{2t^{3/2}}3\bigg|_{t=1}^{t=\cos x}=\left(\dfrac{\cos^2x}2+\dfrac{2(\cos x)^{3/2}}3\right)-\left(\dfrac12+\dfrac23\right)$

$=\dfrac{\cos^2x}2+\dfrac{2\sqrt{\cos^3x}}3-\dfrac76$

c. The derivative of the previous result is

$\dfrac{2\cos x(-\sin x)}2+\dfrac{2\cdot\frac32(\cos x)^{1/2}(-\sin x)}3=-\sin x\cos x-\sin x\sqrt{\cos x}$

which is the same as the answer given in part (a), so ...

d. ... yes
