Circumference = 2×3.14×r
3.14 is pie and r is the radius.
To find the radius you divide the diameter by 2.
19 ÷ 2 = 9.5
2×3.14×9.5 = 59.66
Multiply 59.66 by 6 because ther are 6 pennies.

59.66 × 6 = 357.96 mm.

Which point is an x-intercept of the quadratic equation (x-8)(x+9)

defon

Solve for x in each set of parentheses by setting them to 0:

X -8 = 0

X = 8

X+9 = 0

X =-9

You have two x intercepts (8,0) and (-9,0)

You didn’t list any choices to pick from but it would be either if the ones above.

Somebody answer !!!!!

Rainbow [258]

Answer:

Step-by-step explanation:

First we have to subtract 5 from both sides

$\sqrt{x-6} +5=12\\\\\sqrt{x-6}+5-5=12-5\\\\\sqrt{x-6}=7$

Now, square both sides

$(\sqrt{x-6})^{2}=7^{2}$

x - 6 = 49

Now, add 6 to both sides

x - 6 +6 = 49 + 6

x = 55

HELP PLEASE ASAP IM SO CONFUSED!!!!!!!!

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

We have the points (-4, -6) and (2, 6). Substitute:

$m=\dfrac{6-(-6)}{2-(-4)}=\dfrac{12}{6}=2\\\\y=2x+b$

Put the coordinates of the point (2, 6) to the equation of a line:

$6=2(2)+b\\\\6=4+b\qquad|-4\\\\2=b\to b=2$

<h3>Answer: y = 2x + 2</h3>
