Answer:

$\\ \frac{y2 - y1}{x2 - x1} = \frac{ - 3 - ( - 3)}{ - 12 - ( - 8)} = \frac{ - 3 + 3}{ - 12 + 8} = 0 \div ( - 4) = 0$

NARA [144]

Answer:

The distance traveled at a constant speed is directly proportional to the time of travel. If Olivia traveled 112 miles in 3.5 hours, how many miles will Olivia travel in 8.9 hours at the same constant speed?

-----------------

Proportion:

x/8.9 = 112/3.5

---

x = 8.9(112/3.5)

x = 284.8 miles

A ball is thrown from a height of 45 meters with an initial downward velocity of 10 m/s. The ball's height h (in meters) after t

dmitriy555 [2]

Answer:

2.16 s

Step-by-step explanation:

When it hits the ground, height h=0 hence

$0=45-10t-5t^{2}$

$5t^{2}+10t-45=0$

$t^{2}+2t-9=0$

Using quadratic formula

$x=-1+\sqrt 10\\ x=-1-\sqrt 10$

Since time can't be negative, $-1+\sqrt 10$

t=2.16 s

Can someone please help me answer this question.?

SashulF [63]

Answer:

d=8.0 meters

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

We are given the volume and the height

117.23 and the height 7

117.23 = 1/3 *3.14 *r^2 * 7

117.23 = 7.3266666666 *r^2

Divide each side by 7.3266666666

117.23/7.3266666666 = 7.3266666666 *r^2/7.3266666666

16.00045496 = r^2

Take the square root of each side

sqrt(16.00045496) =sqrt( r^2)

4.000 = r

We found the radius but it wants the diameter

d = 2*r

d =2*4.0

d=8.0 meters

52.68 feet per hour convert to inches

Ede4ka [16]

632.16 inches per hour is the answer. Find the conversion rate of feet to inches, which is just 1 foot = 12 inches. Then, multiply 52.68 by 12 to get the answer.
Hope this helped.
