Answer:

A) y ^4 − 13 y^ 3 − 6 y

Step-by-step explanation:

4y^4 - 8y^3

- 5y^3 + 6y + 3y^4

----------------------------

flip the equations around

-8y^3 + 4y^4

- 5y^3 + 6y + 3y^4

------------------------

-13y^3 - 6y + y^4

Rearrange to get:

y^4 - 13y^3 - 6y

I hope this helps you out!!!

A block is set in motion hanging from a spring and oscillates about its resting position

coldgirl [10]

Answer:

t = 1.277 sec and t = 2.848 sec

Step-by-step explanation:

This problem is much more easily done by graphing it than by computing it using algebra.

The values of t we're looking for are the ones that make x = 0, so we want the solutions of $0.6sin(2t)+0.4cos(2t)=0$ on the interval [0, 3].

According to the graph, this is true when t = 1.277 seconds and t = 2.848 seconds.

The prices of three t-shirts styles are $24, $30 and $36. the probability of choosing a $24 t-shirt is 1/6. the probability of c

Slav-nsk [51]

$\text{Answer} : \text{The expected value of a t-shirt is \$31.}$

Explanation:

Since we have given that

The prices of three t-shirts styles i.e $24, $30, $36 with their probability is given by

$\frac{1}{6}, \frac{1}{2},\frac{1}{3}$

As we know that,

$E(X)= \sum_{1}^{3}x_iP(x_i)$

$\text{where} x_i \text{ is the prices of t- shirts styles}$

Now,

$x_1= \$24 , x_2=\$30 , x_3=$36$

and

$P(x_1)=\frac{1}{6},P(x_2)=\frac{1}{2}, P(x_3)=\frac{1}{3}$

So,

$E(X)= 24\times \frac{1}{6}+30\times\frac{1}{2}+36\times \frac{1}{3}\\=4+15+12\\=31$

So, the expected value of a t-shirt = $31.

Answer:

its 84!

Step-by-step explanation:

volume of a rectangular prism is length * width * height, since the shape is 3D, or multi-demensional. you take all three numbers and multiply them together :) in this case its 7, 3, and 4. 4 * 3 is 12, and 12 * 7 is 84 :)

How do you determine if the line segments are congruent

Gemiola [76]

You must calculate the length of the segments.

Suppose segments AB and CD
Being A (m, n), B (p, q) C(r,s) and D(t,u)

They are congruent if:

 $\boxed{(p-m)^2+(q-n)^2=(t-r)^2+(u-s)^2}$
