Answer:

a20 = -108

Step-by-step explanation:

53 - 62 = -9

44 - 53 = -9

35 - 44 = -9

Then the intervall is -9

The first number is 63

63 + (19*-9) = 63 - 171 = -108

The company makes a profit of 15% on every faucet sold. What is the profit on one shower faucet ?

Rama09 [41]

Answer:

Hi there!

Your answer is:

D: 18.00$

Step-by-step explanation:

First, we plug in all the numbers under the columns "Kitchen Sink", "Bathroom Sink" and "Shower" in our matrix calculator as A. Then, we plug in all the numbers under "Total Selling Price" in our matrix calc as B. Then, we perform the equation A^-1 * B. We will look to the 3rd row for this, since shower is our "z" and the third row represents z

Since profit is determined by .15 * 120, we calculate this. Your answer is 18.

I need help, I don’t need an explanation, just the answer

Answer:

$x = 48 \: \: \: \: \: \: y = 16$

Step-by-step explanation:

$y = - x + 4y$

$y + x = 4y$

$y + x - 4y = 0$

$- 3y + x = 0$

$- x + 4y = 16$

$- 3y + x = 0$

$- 3y = - x$

$y = - \frac{1}{3} ( - 1)x$

$y = \frac{1}{3} x$

$4 \times ( \frac{1}{3} )x - x = 16$

$\frac{1}{3}x = 16$

$x = 48$

$y = \frac{1}{3} \times 48$

$y = 16$

Hope this is correct and helpful

A ball is thrown into the air with a velocity of 34 ft/s. It's height in feet after t seconds is given by y=34t-26(t)^2. Find th

kkurt [141]

Answer:

The average velocity of the ball at the given time interval is -122.3 ft/s

Step-by-step explanation:

Given;

velocity of the ball, v = 34 ft/s

height of the ball, y = 34t - 26t²

initial time, t₀ = 3 seconds

final time, t = 3 + 0.01 = 3.01 seconds

At t = 3 s

y(3) = 34(3) - 26(3)² = -132

The average velocity of the ball in ft/s is given as;

$V_{avg} = \frac{y(3.01)-y(3)}{3.01 -3}\\\\V_{avg} = \frac{34(3.01)-26(3.01)^2-y(3)}{3.01 -3}\\\\V_{avg} = \frac{-133.223-y(3)}{0.01}\\\\V_{avg} = \frac{-133.223-(-132)}{0.01}\\\\V_{avg} =\frac{-1.223}{0.01}\\\\V_{avg} = -122.3 \ ft/s$

Therefore, the average velocity of the ball at the given time interval is -122.3 ft/s
