Answer:

k = -16

Step-by-step explanation:

Given formula:

4y= -kx - 2, where slope is 4

Slope-intercept formula is:

y = mx + b, where m is the slope

Finding slope by bringing the formula to the same format as above:

4y = -kx - 2
y = -k/4x - 1/2

Slope is -k/4 and comparing it with the given:

-k/4 = 4
k = 4*(-4) = -16

Gala2k [10]

Answer:

50,000 miles

Step-by-step explanation:

First,

If C is the annual operating cost, you can modify/substitute into the equation,

21,100 = 0.37m + 2600

Second, solve the equation for m,

0.37m = 18,500

m = 50,000

A parachute speed during a free fall reaches117 miles per hour What is the speed in feet per second At the speed how many feet w

qwelly [4]

Answer:

Speed is 171.6 ft/s and distance is 1716 feet

Step-by-step explanation:

Given that,

The speed of a parachute = 117 miles per hour.

1 mph = 1.47 ft/s

117 mph = 171.6 ft/s

We need to find the distance it travel during 10 s. We know that the distance covered is equal to the product of speed and time taken. So,

d = vt

$d=171.6\ ft/s\times 10\ s\\\\=1716\ \text{feet}$

Hence, this is the required solution.
