Answer:

f(x) = 2ˣ + 1

Step-by-step explanation:

Based on the exponential increase, you know that it will be an exponential equation, meaning that you can cancel out the first two options.

The easiest way to do pick the between the two remaining equations is by plugging in an x-value and seeing if the y-value for that equation matches the y-value from the equation.

For (3, 9):

f(x)  =  3ˣ  =  3³  =  27

f(x)  =  2ˣ + 1  =  2³ + 1  =  8 + 1  =  9

The last equation is the equation that is represented by the table.

A high school track is shaped as a rectangle with a half circle on either side.
Ilia_Sergeevich [38]

Answer:

Option (3)

Step-by-step explanation:

Track is shaped as a rectangle with a semicircle on either side.

Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.

= 2(96) + 2πr

= 192+2\pi (\frac{35}{2})

= 192 + 35π

= 192 + 109.9

= 301.9 m

Since, Jake plans to run four laps.

Therefore, distance covered by Jake = 4 × 301.9

                                                              = 1207.6 m

Option (3) will be the correct option.

The profit a company earns every month depends of the amount of product sold, p, for $855 each and the amount spent in rent, uti
3241004551 [841]
Profit = (selling price x number of units) - expenses in this case, the selling price is $855, number of units is 250, and the expenses are $6,780 So, Profit = ($855 x 250) - $6,780 = $206,970 That number times 15% (decimal = 0.15) will be the salary of the CEO So, $206,970 x 0.15 = $31,045.50

Kamila [148]
To find b you would be using the equation y=mx+b so to find be simply look at your equation and put your numbers in place so the answers so you would put your answers for the first one y=(m=-2)x(b=-3)
so easily the answers to these would be a=-3, b=-3 ,c=-4 ,d=-2
