y=mx+b is he form you need.

your slope would be 3 and your y intercept is 0 so y=3x is the answer.

Answer:

4:25

Step-by-step explanation:

Given that,

r₁ = 15 inches, r₂ = 6 inches

The area of the cylinder is given by :

$A=2\pi rh+2\pi r^2$

The ratio of surface areas of two cylinders,

$\dfrac{S_2}{S_1}=\dfrac{2\pi r_2h_2+2\pi r_2^2}{2\pi r_1h_1+2\pi r_1^2}\\\\\dfrac{S_2}{S_1}=(\dfrac{r_2}{r_1})^2\\\\=\dfrac{6}{15}^2\\\\=\dfrac{4}{25}$

Hence, the required ratio is 4:25.

Answer:

$D.\ y = 3\sin(2(x + \frac{\pi}{4}))$

Step-by-step explanation:

Given

$A = 3$ --- Amplitude

$C = \frac{\pi}{4}$ --- Right phase shift

Required

Identify the function

A sinusoidal function is defined as:

$y = A\sin(B(x + C)) + D$

Substitute values for A and C

$y = 3\sin(B(x + \frac{\pi}{4})) + D$

By comparison, only option (D) has the above format where

$y = 3\sin(2(x + \frac{\pi}{4}))$

Hence (D) is correct

X(x+1)-1=4<br> ---<br> please help stuck on this question

Sloan [31]

Answer:

x=2

Step-by-step explanation:

use distributive property: x^2+2x-1=4

remove the -1 by adding 1 on both sides: x^2+2x=5

use the guadratic fromula: ax²+bx+c=0

plug in the equation x^2+2x-5=0

a,b and c are the coefficients to plug into the formula

a=1, b=2, c=-1

Finally, you will find that x=2
