Answer:

x = -1

Step-by-step explanation:

30 = 2.5(10)(-2x) - you multiply by each

30 = 25 - 5x - then pass 25 to the other side and subract

5x = - 5x - then divide 5 / -5

x = -1 - and you have the answer

Answer:

x= -1

Step-by-step explanation:

distribute 2.5 through the parenthese

30=25-5x

move variable to the left hand side an change its sign

5x+30 =25

move constant to the right hand side and change the sign

5x=25 -30

calculate the difference

5x= -5

divide both sides of the equation by 5

x= -1

Hope this helps!!! I would really appreciate a brainliest???

Answer:

Find the missing side first.

x = $\sqrt{12^2 - 7^2} = \sqrt{144 - 49} = \sqrt{ 95}$

1) tangent = opposite leg / adjacent leg

tanβ = √95/7
Correct choice is B

2) sine = opposite leg / hypotenuse

sinβ = √95/12
Correct choice is D

Answer:

Step-by-step explanation:

${5}^{2} + {x}^{2} = {7}^{2} \\ 25 + {x}^{2} = 49 \\ {x}^{2} = 49 - 25 \\ {x}^{2} = 24 \\ x = \sqrt{24}$

Find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.

kherson [118]

Answer:

$=\frac{364\pi}{3}$ cubic units

Step-by-step explanation:

We are to find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.

f(x)=2x+1, y=0, x=0, x=4.

The picture is given as shaded region.

This is rotated about x axis

Limits for x are already given as 0 and 4

f(x) is a straight line

The solid formed would be a cone

Volume = $\pi \int\limits^a_b {(2x+1)^2} \, dx \\= \pi \int\limits^4_0 {(4x^2+4x+1)} \, dx \\=\pi [\frac{4x^3}{3} +2x^2+x]^5_0\\\\=\pi[\frac{4*4^3}{3}+2*4^2+4-0]\\=\frac{364\pi}{3}$
