Lauri is picking out material for her new quilt. At the fabric store, there are 1919 solids, 99 striped prints, and 1212 floral

Masteriza [31]

Answer:

1,79,07,120 ways

Step-by-step explanation:

Ways in which 3 solids can be chosen from 19 solids = 19 c 3

33 striped prints can be chosen from 99 striped prints in 9 c 3 ways

33 floral prints can be chosen from 121 floral prints in 12 c 33 ways

So, total ways = (19 c 3) (9 c 3) (12 c 3)

(969) (84) (220)

Please help!! x = 2 - 3 cos t, y = 1 + 4 sin t in rectangular form?<br><br> thank you! :)

Answer:

$\frac{(x-2)^2}{9}+\frac{(y-1)^2}{16}=1$

Step-by-step explanation:

$x=2-3\cos(t)$

$y=1+4\sin(t)$

Let's solve for $\cos(t)$ in the first equation and then solve for $\sin(t)$ in the second equation.

I will then use the following identity to get right of the parameter, $t$ :

$\cos^2(t)+\sin^2(t)=1$ (Pythagorean Identity).

Let's begin with $x=2-3\cos(t)$ .

Subtract 2 on both sides:

$x-2=-3\cos(t)$

Divide both sides by -3:

$\frac{x-2}{-3}=\cos(t)$

Now time for the second equation, $y=1+4\sin(t)$ .

Subtract 1 on both sides:

$y-1=4\sin(t)$

Divide both sides by 4:

$\frac{y-1}{4}=\sin(t)$

Now let's plug it into our Pythagorean Identity:

$\cos^2(t)+\sin^2(t)=1$

$\frac{x-2}{-3})^2+(\frac{y-1}{4})^2=1$

$\frac{(x-2)^2}{(-3)^2}+\frac{(y-1)^2}{4^2}=1$

$\frac{(x-2)^2}{9}+\frac{(y-1)^2}{16}=1$

What is the volume of a block of ice measuring 3 meters long, 1.5 meters wide, and 2 meters high? A. 900 cu. m B. 12 cu. m C. 9

lutik1710 [3]

To find volume of a rectangular prism, you simply need to multiply length times width times height. We know from the text that our block of ice is 3 meters long, 1.5 meters wide, and 2 meters high. So all we need to do is multiply:

3 * 1.5 = 4.5

4.5 * 2 = 9

The block of ice has a volume of 9 cubic meters.
Choice C is your correct answer.
Hope that helped! =)
