Gabriela bought a new pair of sunglasses when they were having a 30% off sale if the regular price of the glasses was 72% how mu
serg [7]
Answer is: 50.4%. You have to take 30% off of 72%. Easiest way is to find 10% of 72 (7.2) and multiply that by 3 (=21.6). Then minus this off the original price (72 - 21.6 = 50.4)

A person borrows $10,000 and repays the loan at the rate of $2,400 per year. The lender charges interest of 10% per year. Assumi
omeli [17]

Answer:

a) M(t)=24000-14000e^{t/10}

b) It takes 5.390 years to pay off the loan.

Step-by-step explanation:

(a) The differential equation for the variation in the amount of the loan M is

\frac{dM}{dt}=0.1M-2400

We can express this equation as:

\frac{dM}{dt}=0.1M-2400\\\\10\int \frac{dM}{M-24000} =\int dt\\\\10ln(M-24000)=t\\\\M-24000=Ce^{t/10}\\\\M=Ce^{t/10}+24000\\\\M(0)=Ce^{0/10}+24000=10000\\\\C+24000=10000\\\\C=-14000\\\\M(t)=24000-14000e^{t/10}

(b) We can calculate this as M(t)=0

M(t)=24000-14000e^{t/10}=0\\\\e^{t/10}=24000/14000=1.714\\\\t=10ln(1.714)=10* 0.5390=5.390

It takes 5.390 years to pay off the loan.

Which equation has the least steep graph?
MAVERICK [17]

Answer:

y=\frac{1}{4}x+6

Step-by-step explanation:

y=\frac{1}{4}x+6 is the least steeped graph

  1. The greater the slope, the steeper the line.
  2. Also you use the absolute values of the slopes when determining the steepness.
  • So here it would be: \frac{3}{4},7,\frac{1}{4},2
  • Now, arrange them from least to greatest: \frac{1}{4},\frac{3}{4},2,7

As you can see, \frac{1}{4} is the smallest number/slope.

Hope this helps!
