Answer:
= 0.05P - 150
Step-by-step explanation:
Let P(t) be the balance of the loan at time t years,
Let P(t) will satisfy 
where r = annual interest rate
R = per year payment rate
R = $150/year
r = 
= 0.05
Now we have the following picture,
Interest Balance Payment
5% ⇒ P(t) ⇒ $150/year
(0.05)
Therefore, a linear ODE satisfied by P(t) is given by
= 0.05P - 150
Answer:
6 miles
Step-by-step explanation:
The benchmark number are 0 1/2 and 1, so we round to the nearest whole number or 1/2 number
3 1/8 miles is close to 3
2 5/6 miles is close to 3 (5 is very close to 6 to 5/6 is close to 1)
We are adding
3 1/8 + 2 5/6
3 + 3 = 6
About 6 miles
Answer:
x = 2
y = 2
Step-by-step explanation:
y = 3x-4
2x + y - 6 = 0
-3x+y = -4
2x + y = 6
-5x = -10
x = 2
y = 2
Answer:
1.95 x 10^5
Step-by-step explanation:
First look at the 4th digit in the number 194720 as the the question said to round to 3 significant figures. If the 4th digit is more than 5, then add 1 to the third digit which results in 195000. Now the question also said to express in standard form. Look for the first non-digit number in 195000. After 1 put a decimal point and remove all the zeros after the point which results in 1.95. Now count how many digits you moved to the left which comes as 5. Write the answer as 1.95 x 10^5.
Hope you can understand this!!
Answer:
cot(- 90)° = 0
Step-by-step explanation:
Using the identity
cot x = 
, then
cot(- 90)° = 
= 
= 0
