Step-by-step explanation:

find the area of the circle and take away 1/4 of the area (because the angle taken away is 90) then you have the answer.

Answer:

9.4275

Step-by-step explanation:

First you find the area of the circle without the cut portion which is

2 times 2 = 4. Then 4 times 3.14 = 12.57.

Now that we found the total area of the circle we need to subtract the removed portion. What you can see here is that the circle is cut by 25% so that means only 75% of it still remains. 75% of 12.57 is = 0.75 multiplied by 12.57 which is 9.4275

On a recent trip to the convenience store, you picked up 4 gallons of milk, 6 bottles of water and 5 snack size bags of chips. Y

Answer:

Milk $3.60

Water $1.80

Chips $0.90.

Step-by-step explanation:

If w = cost of 1 bottle of water, m = cost of 1 gal of milk and c cost of 1 bag of chips we have.

4m + 6w + 5c = 29.7

Also we have w = 2c and m = 1.8 + w.

From the first equation we have c = w/2.

So substituting for c and m in the initial equation we have:

4(1.8 + w) + 6w + 5(w/2) = 29.7

7.2 + 4w + 6w + 2.5w = 29.7

12.5w = 22.5

w = 1. 80.

So c = w/2 = 1.8/2 = 0.90.

and m = 1.8 + 1.8 = 3.60.

Match the absolute value expression to its correct distance from zero on the number line.

Kaylis [27]

Answer:

Step-by-step explanation:

The value of the expression is its distance from zero. The absolute value is the positive value without any minus sign.

$|-7.1|=7.1\\\\|2.7+4.2|=|6.9|=6.9\\\\|4-9|=|-5|=5\\\\|-3.1+8.8|=|5.7|=5.7$

Find the length of a curve. y=(4-x^2/3)^3/2 from x=1 to x=8

Aneli [31]

$y=\left(4-x^{2/3}\right)^{3/2}\implies y'=\dfrac32\left(4-x^{2/3}\right)^{1/2}\left(-\dfrac23x^{-1/3}\right)=-\dfrac{\left(4-x^{2/3}\right)^{1/2}}{x^{1/3}}$

The arc length is given by

$\displaystyle\int_1^8\sqrt{1+\left(-\dfrac{\left(4-x^{2/3}\right)^{1/2}}{x^{1/3}}\right)^2}\,\mathrm dx=\int_1^8\sqrt{\dfrac4{x^{2/3}}}\,\mathrm dx=\int_1^82x^{-1/3}\,\mathrm dx=9$
