Mathematics

Answer: m = 4/7

Step-by-step explanation:

x = m

y = 2m+1

so

x+3y = 7

or, m+3(2m+1) = 7

or, m + 6m+3 = 7

or, 7m = 4

so m = 4/7

Need help question #3. Show steps please
Oksana_A [137]

Answer:

B.

Step-by-step explanation:

We are given:

\displaystyle \int \sqrt{x}\Big(9x^3-2\sqrt{x}+\frac{8}{x}\Big)\, dx

And we want to select its equivalent form.

Note that A is not valid. No integration property allows us to separate factors unless that factor is a constant.

We can simply rewrite and then distribute. First, by rewriting:

\displaystyle =\int x^{1/2}\Big(9x^3-2x^{1/2}+8x^{-1}\Big)\, dx

Distribute. Recall exponent properties;

\displaystyle =\int(9x^{3+1/2}-2x^{1/2+1/2}+8x^{-1+1/2})\, dx

Simplify:

\displaystyle=\int9x^{7/2}-2x+8x^{1/2}\, dx

This can then be separated (since its addition/subtraction) and integrated individually.

Hence, our answer is B.

Rounded to the nearest whole number, how many 2ft by 2ft squares will fit into circle that has a diameter of 20 feet?
seraphim [82]

Answer:

79

Step-by-step explanation:

The area of a circle is pi*radius^2; the radius of this circle is 10 (20/2=10). Our area is then 100pi or ~314 square feet. A 2x2 square takes up 4 feet. 314/4 is equal to 78.5, or when rounded, 79

nekit [7.7K]

Answer:

$43.20

Step-by-step explanation:

A swimsuit that originally cost $90 before any discount is on sale for 20% off.

X = price of swimsuit

X = 90

20% off = 90 * 0.8 = 72

The swimsuit is then put on clearance for an additional 40 % off the sale price.

72 * 0.6 = 43.2

what is the final price?

$43.20
