What is the answer to this

lianna [129]

Answer:

Hi

Step-by-step explanation:

$v = \pi \: d \\ \\ v = 14 \times \pi = 14\pi \: cm$

in this formula

d is diameter

v is circumference

because the question asked the answer in terms of pi so we write the pi its self

hope this help you

god bless you and us

Find the equation of a line that is parallel to the line y = -4× and contains the point (8,-3)

astra-53 [7]

(Note: this is hard to explain without graphing. You might want to graph both of these lines just to make sure I did this correctly. :))

Y = -4(x) is the y = mx + b where m = slope and b = the y intercept.

So the slope of line A is -4 / 1 and the y intercept is 0. (If it's 0 there is no point in writing it down, so it was left out of the equation.)

The slope of line B with be equal to the slope of line A, so we can fill that in our equation. y = -4 x + ??

We know that y increases as x decreases.

Now we just need to scale 8, -3 down until x = 0.
(8 - 4, -3 + 1) = (4, -2)

(4 - 4, -2 + 1) = (0, -1)

y = -4x -1 is your final answer. Hope that helps! :)

Holding a ruler upright at arm’s distance (24 in.), Ronnie aligned the bottom of the ruler with a mark on the utility pole that

atroni [7]

Answer:

10 feet

Step-by-step explanation:

Drawing obviously not to scale but... Red segment is the ruler, at least the part between 5 and 6 inches, 1 inch long. Brown segment is the pole, ground to the top. Leftmost point is the eye, green line is the horizontal. The triangles are similar (AAA, the vertical lines are parallel), the ratio of the side is the same as the ratio of the heights. The height of the larger triangle (measured across the green line is

$40 yd \times 3\frac{ft}{yd} \times 12\frac{in}{ft}= 1440''$ .

Ratio of the height is then $1440\div24 = 60$ .

At this point the height of the pole is 60 times the length of the measure on the ruler, or 60 inches, that is 5 feet. Add the 5 feet the pole was starting from, it's 10 feet.

Soren solves the quadratic equation x^2 + 8x – 9 = 0 using the quadratic formula. In which step did Soren make an error?

pochemuha

Answer:

step 3 didn't divide by 2

Step-by-step explanation:

in step

$\frac{ - 8 + \sqrt{100} }{2} = \frac{ - 8 + 10}{2} = 1 \\ \frac{ - 8 - \sqrt{100} }{2} = \frac{ - 8 - 10}{2} = - 9$
