Answer:
<h2>$212.8</h2>
Step-by-step explanation:
If the car loses 11.1% per year, we need to calculate how much money is that:
; this value is the lost per year.
Now, in order to calculate this loss per month, we divide it by 12:
Hence, the monthly value decrease is $212.8, rounding it to the tenth.
Step-by-step explanation:
numbers
first = X
second = (x-10)
Third = 4(x-10)
x + (x-10) + 4(x-10) = 124
2x -10 + 4x-40 =124
6x - 50 = 124
6x = 124 + 50
6x = 174
x= 29
therefore the ;
first number = 29
second = (x-10) = 29-10 = 19
third= 4(x-10) = 4(29-10)= 76
The value of sin-1(1) is negative startfraction pi over 2 endfraction, startfraction -pi over 2 endfraction.
<h3>What is the value of sin (π/2)?</h3>
The value of sin (π/2) is equal to the number 1. The value of the sin-1(1) has to be find out.
Suppose the value of this function is <em>x</em>. Thus,
Solve it further,
......1
The value of sin (π/2) and -sin (-π/2) is equal to 1 such that,
Put this value in the equation 1,
Thus, the range will be,
Thus, the value of sin-1(1) is negative startfraction pi over 2 endfraction, startfraction -pi over 2 endfraction.

Answer:
Step-by-step explanation:
Maria can paddle her canoe 2 miles upstream against the current in the same time it would take her to paddle 6 miles downstream.
Maria can paddle 2mph in still water.
What is the speed of the current?
:
let c = the rate of the current
then
(2-c) = effective speed upstream
and
(2+c) = effective speed downstream
:
Write a time equation; time = dist/speed
Two mi upstr time = six mi downstr time
2%2F%28%282-c%29%29 = 6%2F%28%282%2Bc%29%29
Cross multiply
2(2+c) = 6(2-c)
4 + 2c = 12 - 6c
2c + 6c = 12 - 4
8c = 8
c = 1 mph is the current
:
:
Check this, find the time each way,
effective speed down: 2 + 1 = 3 mph
effective speed up: 2 - 1 = 1 mph
6/3 = 2 hr
2/1 = 2 hrs
The formula for calculating the height is h = 3V/πr²
<h3>Subject of the formula</h3>
The formula given is the formula for calculating the volume of a cone
V = 1/3πr²h
where
h is the height
r is the radius
Make h the subject of the formula
Cross multiply
3V = πr²h
Divide both sides by πr²
3V/πr² = πr²h/πr²
h = 3V/πr²
Hence the formula for calculating the height is h = 3V/πr²
