Answer:
Step-by-step explanation:
We are given the following information in the question:
where, R is the tip speed, T is the speed tip of blade and W is the speed of wind.
We have to find , whem W = 75 km per hour, , T = 150 km per hour
Formula:
Putting all the value, we have:
I^3 = i * i * i = i^2 * i = -1 * i = -i Answer
Its D
Haven’t done this in a while but the first is rational, second is irrational, third is rational, fourth is irrational, fifth is rational, sixth is rational, seventh is irrational
Answer:
$441
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.5%/100 = 0.035 per year,
then, solving our equation
I = 2400 × 0.035 × 5.25 = 441
I = $ 441.00
The simple interest accumulated
on a principal of $ 2,400.00
at a rate of 3.5% per year
for 5.25 years is $ 441.00.
The new value after the original value is increased by 30% is 1.3 times the original value.
<h3>
Percentage</h3>
Percentage is used to express a fraction number or decimal in fraction of hundred. It is given by:
Percentage = [(new value - original value) / original value] * 100%
Let x represent the new value and y represent the original value, hence:
30% = [(x - y)/y] * 100%
0.3 = (x - y)/y
x - y = 0.3y
x = 1.3y
The new value after the original value is increased by 30% is 1.3 times the original value.
