Answer:

C.) 3.80*2.01^x

Step-by-step explanation:

Given the data :

-4 - - - -> 0.25

-3 - - - -> 0.5

-2 - - - - > 0.9

-1 - - - - - > 1.9

0 - - - - - -> 3

1 - - - - - - > 7

2 - - - - - > 18

3 - - - - -> 30

4 - - - - - > 68

The exponential regression equation is expressed in the form:

y = a * b^x

Where a = Initial value or value on the y-intercept

b = constant value

x = input value

Using the online exponential regression calculator :

y = 3.80 * 2.01^x

AnnyKZ [126]

Red shirts and blue shirts equally count to his bonus, so he has 15 + 23 = 38 shirts sold at this moment. He needs to sell 75 shirts for the bonus. We subtract our goal from what he have; 75 - 38 = 37.


The strategy here: subtract the goal (75 shirts) from what you did to get to the goal (15 shirts and 23 shirts).


Nathan needs to sell 37 more shirts for the bonus. Hope this helps.

If g(n) varies inversely with n and g(n) = 8 when n = 3, find the value of n when g(n) = 6.
liraira [26]

Answer: Last option.

Step-by-step explanation:

By definition, Inverse variation equations  have this form:

y=\frac{k}{x}

Where "k" is the constant of variation.

In this case, it is:

g(n)=\frac{k}{n}

Knowing that g(n) = 8 when n = 3, we can substitute values into the equation and solve for "k":

8=\frac{k}{3}\\\\8*3=k\\\\k=24

Therefore, we can find the value of "n" when g(n) = 6 by substiuting this value and the value of "k" into the equation and solving for "n". Then:

6=\frac{24}{n}\\\\6n=24\\\\n=\frac{24}{6}\\\\n=4

Answer:

  A.  0 = −(x−6)^2+12

Step-by-step explanation:

The vertex form of a quadratic equation is ...

  y = a(x -h)² +k . . . . . . for vertex (h, k) and scale factor 'a'

When the given vertex (h, k) = (6, 12) is used, we find the form of the equation to be ...

  y = a(x -6)² +12

The ball will be on the ground when y = 0. Here, the vertical scale factor 'a' is -1, so the equation representing the ball being on the ground is ...

  0 = -(x -6)² +12 . . . . . . matches choice A

Answer:384cm²

Step-by-step explanation:

first find the area of the parallelogram

bh

b=24

h=7.5

24×7.5=180

second find the area of a rectangle

lw

l=24

w=8.5

24×8.5=204

add the areas together

204+180=384cm²
