1. The midpoint of GH is (-2,3), and its endpoints are G (g,4) and H (-2,h). What are the values of g and h

alina1380 [7]

Answer: $(g,h)=(-2,2)$

Step-by-step explanation:

Given

Midpoint is $(-2,3)$

Endpoints are $G(g,4)$ and $H(-2,h)$

Mid point of any two point is given by

$x=\frac{x_1+x_2}{2}$

and $y=\frac{y_1+y_2}{2}$

So, $-2=\frac{g+(-2)}{2}$

$-4=g-2$

$g=-2$

Also

$3=\frac{4+h}{2}$

$6=4+h$

$h=2$

Therefore $(g,h)=(-2,2)$

What is the approximate circumference of the circle shown below?

aniked [119]

Answer:

D: 109 cm

Step-by-step explanation:

The formula of circumference is

$\pi d$

Diameter =

$17.4 \times 2 = 34.8$

Hence, circumference =

$34.8 \times \pi = 109.32742...$

rounded of to 109.

4n^(2)+4n=3<br> Please help with the work

Kaylis [27]

Answer:

n= 1/2 ( $\frac{1}{2}$ ) or (0.5)

AND

n= -3/2 ( $-\frac{3}{2}$ ) or (-1.5)

Step-by-step explanation:

4n^2+4n=3

step1: move 3 to the other side and make the equation equal to zero.

4n^2+4n-3=0

step2: factorise the equation.

(2n-1)(2n+3)=0

step3: make each bracket equal to zero.

2n-1=0

2n+3=0

step4: solve for n values.

<u>1.</u> 2n-1=0

(add 1 for both sides)

2n=1

(divide by 2 for both sides)

n= 1/2 ( $\frac{1}{2}$ ) or (0.5)

<u>2.</u> 2n+3=0

( subtract 3 for both sides)

2n=-3

(divide by 2 for both sides)

n= -3/2 ( $-\frac{3}{2}$ ) or (-1.5)
