What is the Circumference of a circle if its radius in 15 inches? Please help always a procrastinator in math! Thanks!

1 answer:

7 0

Circumference Formula:
$C = 2\pi \times R$
R = Radius = 15 in

$C = 2\pi \times 15$
$C = 30\pi \: inches$

Or C = 94,2 inches

The equation y minus two-thirds = negative 2 (x minus one-fourth) is written in point-slope form. What is the equation in slope-

Lena [83]

Answer:

(B) $y=-2x+ \dfrac{7}{6}$

Step-by-step explanation:

Given the point-slope form of the equation of a line below:

$y-\dfrac{2}{3}=-2\left(x- \dfrac{1}{4}\right)$

We are required to write it in the slope-intercept form, y=mx+c.

$y-\dfrac{2}{3}=-2\left(x- \dfrac{1}{4}\right)\\\\y-\dfrac{2}{3}=-2x+ \dfrac{2}{4}\\\\y=-2x+ \dfrac{2}{4}+\dfrac{2}{3}\\\\y=-2x+ \dfrac{7}{6}$

The slope intercept form is:

$y=-2x+ \dfrac{7}{6}$

<u>The correct option is B.</u>

Choose the graph which represents -6x - 5y = -10

Anna007 [38]

Answer:

y = 2 + ((-)6/5)x

Step-by-step explanation:

-6x-5y=-10

add 6x to both sides.

-5y = -10 +6x

divide both sides by -5

y = 2 - (6/5)x

Plug in 0 for x to get the y intercept:

f(0) = 2 - (6/5) (0)

y = 2

(0, 2) is the y intercept.

Do the same for values such as -1, -2, 1, and 2, etc.

Then graph it.

Anyone know the answer ???

mafiozo [28]

Hello!

Since the angles are same side alternate angles they are equal to each other

60 - 2x = 70 - 4x

We solve this algebraically

Add 4x to both sides

60 + 2x = 70

Subtract 60 from both sides

2x = 10

divide both sides by 2

x = 5

Hope this helps!
