Answer:

4^2 + (-7)^2

Step-by-step explanation:

The square of the distance is given by the distance formula as ...

d^2 = (x2 -x1)^2 + (y2 -y1)^2 = (3 -(-1))^2 + (-5-2)^2

= 4^2 +(-7)^2 . . . . . matches the second choice (sort of)

<em>Comment on notation</em>

Clearly, you understand the use of the caret (^) to signify exponentiation. The number 42 is very different from the value of 4^2 = 16. A caret is required.

Answer:

g(q) = 5/8q

Step-by-step explanation:

-7q + 12r = 3q - 4r

Add 4r to each side

-7q + 12r+4r = 3q - 4r+4r

-7q +16r = 3q

Add 7q to each side

-7q+7q +16r = 3q+7q

16r = 10q

Divide each side by 16

16r/16 = 10q/16

r = 5q/8

g(q) = 5/8q

Answer:

(D)9 divided by sin 60 degrees

Step-by-step explanation:

From the given figure, using trigonometry

$\frac{BC}{AB}=sin60^{{\circ}}$

Substituting the given values, we get

$\frac{9}{AB}=sin60^{{\circ}}$

$\frac{9}{sin60^{\circ}}=AB$

$AB=\frac{9{\times}2}{\sqrt{3}}$

$AB=\frac{18}{\sqrt{3}}$

$AB=10.4 feet$

Thus, The length of the support AB is 9 divided by sin 60 degrees.

Solve for x. Show each step please . Circle your final answer. <br> 2(8-12x)+8x= -25x+52

Vera_Pavlovna [14]

Answer:

x = 4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(8−12x)+8x=−25x+52

(2)(8)+(2)(−12x)+8x=−25x+52(Distribute)

16+−24x+8x=−25x+52

(−24x+8x)+(16)=−25x+52(Combine Like Terms)

−16x+16=−25x+52

Step 2: Add 25x to both sides.

−16x+16+25x=−25x+52+25x

9x+16=52

Step 3: Subtract 16 from both sides.

9x+16−16=52−16

9x=36

Step 4: Divide both sides by 9.

9x/9 = 36/9

x = 4
