PLEASE HELPP I AM FAILING AND I NEED THIS ASAP!!! TYSM

Answer:

See below for answers

Step-by-step explanation:

Do you mean $f(x)=2sin(x-1)$ or $f(x)=2sin(x) -1$ ?

Use the formula $f(x)=asin(bx+c)+d$ where $|a|$ is the amplitude, $-\frac{c}{b}$ is the phase shift, $d$ is the vertical shift, and the period is $\frac{2\pi}{|b|}$ .

Assuming your first case is true, the amplitude would be $|a|=|2|=2$ , your period is $\frac{2\pi}{|1|}=2\pi$ , and your midline/vertical shift is $d=0$ .

Assuming your second case is true, everything but the vertical shift stays the same. It would be $d=-1$ in this case.

A rectangle is divided into equal squares. One row covers 1/8 of the whole rectangle. There are 3 squares in each row. How many

LenaWriter [7]

Answer:

There are 24 squares in the entire rectangle

Step-by-step explanation:

Trom the problem, we are given that one row covers 1/8 of the entire rectangle.

We are also told that this one row, contains three squares.

In other words, what this means is that three squares cover 1/8 of the entire rectangle.

The question is now if three squares cover only 1/8 of the rectangle, how many squares cover the whole rectangle.

In fraction, we can represent a whole using 1/1

We can set up a simple relation to this effect.

3 squares give 1/8 of the rectangle

x squares give 1/1 of the rectangle

cross multiplying, we have

x = 3 ÷(1/8) = 24

Therefore, there are 24 squares in the entire rectangle

Which answer is equivalent to 4 1/3*4 1/6?<br> a. 16<br> b .6√16<br> c. 2<br> d. 3√4

Talja [164]

Answer:

Step-by-step explanation:

$4^\frac{1}{3}\cdot4^\frac{1}{6}\\\\\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=4^{\frac{1}{3}+\frac{1}{6}}=4^{\frac{1\cdot2}{3\cdot2}+\frac{1}{6}}=4^{\frac{2}{6}+\frac{1}{6}}=4^\frac{2+1}{6}=4^\frac{3}{6}=4^\frac{3:3}{6:3}=4^{\frac{1}{2}}\\\\\text{use}\ a^\frac{m}{n}=\sqrt[n]{a^m}\\\\=\sqrt[2]{4^1}=\sqrt4=2$
