You have to look for -3 on the x axis, and then proceed vertically (in this case upwards) until you meet the graph.

We land about 1/2 square above the 12 mark on the y axis. Since one square is 1/2 unit, a half square would be 1/4 unit.

So, we can estimate f(-3)\approx 12.25

a. $24,512.32

b. $712.32

Step-by-step explanation:

a. A price of car $15,300, Tony made a down payment of $3900 so car has $11,400 left of a price and took out a loan.

He paid monthly payments of $252.34 for 4 years. Which mean $252.34 is paid for 48 months, multiplication $252.34 and 48 are $12,112.32. So we have monthly payments is $12,112.32

The total amount Tony ended up for the car is $11,400 + $12,112.32 = $24,512.32

b. The interest Tony pay on the loan is $12,112.32 - $11,400 = $712.32

a stock was selling at $120 per share. a month later, it was selling at $150 per share. what is the percent increase?
goldfiish [28.3K]

Answer:

25%

Step-by-step explanation:

The formula to find percent increase is 100 * \frac{final-initial}{|initial|}. We're given the initial value as 120 and the final value as 150.

  • 100*\frac{150-120}{|120|}
  • 100*\frac{30}{120}
  • 100*\frac{1}{4}
  • 100/4
  • 25

Therefore, the percent increase is 25%.

The width of the figure below is 5 units. The perimeter of the figure is 18 units. What is the length of the figure in units?
marishachu [46]

if the figures perimeter is 18 units, and the width of the figure is 5 units. I am guessing the figure is a rectangle


where the width is 5 units, and 2 of the sides have 2 be the same 2 be a rectangle, than the width on each side is 10 units all together


18-10= 8


if the figure is a rectangle then that means there are 2 sides left of equal length so if we divide our current number (8) by 2 then we will have the length of each side (4)


8 divided by 2= 4


width= 5

length= 4
