Answer:

QR is equal to 5 since 13 is 5 less that 18. So since 13 was already taken, that leaves 5

What is the length of segment CD question mark

mars1129 [50]

Answer:

CD = two square root of 10 end square root

Step-by-step explanation:

To find the length of a segment, use the distance formula. Substitute the order pairs for the endpoints of the segment. CD has the end points (-7, -4) and (-1, -2).

$d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2} \\\\d = \sqrt{(-4--2)^2 + (-7--1)^2} \\\\d = \sqrt{-2^2 + -6^2}\\\\d = \sqrt{4 + 36}\\\\d=\sqrt {40} = 2\sqrt{10}$

AveGali [126]

Answer:

$\displaystyle y = -\frac{x}{5} - 2\frac{1}{5}$

Step-by-step explanation:

$\displaystyle x + 5y = -11 → 5y = -x - 11 → \frac{5y}{5} = \frac{-x - 11}{5} \\ \\ y = -\frac{1}{5}x - 2\frac{1}{5}$

Which of the following is equivalent to<br> (5) 3<br> O 54<br> O 54<br> 05<br> O V5

IrinaK [193]

Answer:

D. $\sqrt[3]{5^7}$

Step-by-step explanation:

The formula for this conversion is:

$a^\frac{x}{n}=\sqrt[n]{a^x}$

Substitute the values you currently have.

$5^\frac{7}{3}=\sqrt[n]{a^x}$

Since we know that

a = 5

x = 7

n = 3

Fill the square root with this.

$5^\frac{7}{3}=\sqrt[3]{5^7}$

The positive numbers will out rule the negative number. It's sort of like placing blocks over another set of blocks. :)
