Answer: The interest is: $528.00
Step-by-step explanation:
Formula ⇒ I = PRT
⇒ <u>P</u> is the principal amount, $2200.00.
⇒<u>R</u> is the interest rate, 12% per year, or in decimal form, 12/100=0.12.
⇒ <u>T</u> is the time involved, 2....year(s) time periods.
⇒So, t is 2 year time periods.
⇒ Finally, To find the simple interest, you just multiply 2200 × 0.12 × 2 to get that:
The interest is: $528.00

7 & 8/10 or 78/10 ( which is the same thing)
Answer:
The answer is B) 1/25
Step-by-step explanation:
This is because given that f(x) = 5^x
Hence, f(-2) would be 5^-2, which is equal to (1/5^2) => 1/25
Because a^-b can be written as 1/a^b
Answer:
The speed in of the plane is 115.47 m/sec
Step-by-step explanation:
Given:
Height at which the plane is flying = 6000 m
Angle of elevation at the radar base = 30 Degrees
Angle of elevation at the radar base after one minute = 60 Degrees
To Find:
The Speed of the plane in meter per second = ?
Solution:
Let us use the tangent of the angle to find the distance (d) to a point directly below plane:
<u>when the angle is 30 degrees</u>



d1 = 10392.3 meters
<u>when the angle is 60 degrees</u>



d2 = 3464.1 meters
<u>distance travelled by aircraft in 1 min is </u>
=>d1 - d2
=>0392.3 - 3464.1
= 6928.2 m/min
<u>Now converting to m/sec</u>
=>
=>115.47 m/sec
The inverse of the function is f(x) =
+ 8
In order to find the inverse of any function, start by switching the f(x) and x. Then solve for the new f(x). The result will be the inverse function. The work is below for you.
f(x) =
----> Switch f(x) and x
x =
----> Cube both sides
= f(x) - 8 ----> Add 8 to both sides
f(x) =
+ 8
