Answer:
Highly dependent on what a and b is.
Step-by-step explanation:
Highly dependent on what a and b is.
If a = 0 and b = 0, then 0^2*0^2 = 2(0)(0)
0 = 0 (true)
If a = 1 and b = 1 then 1^2*1^2 = 2(1)(1)
1 != 2 (false)
The answer is d. They are similar by angle angle
Answer:
24,00
Step-by-step explanation
Correct! The grocer has 2,400 customers.
The whole is the unknown.
Set up a proportion with the known values and solve for the whole.
part = 480 customers, percent = 20%, whole = ? customers
480?=20100
Multiply the numerator and denominator of a fraction by the same number to determine an equivalent fraction.
Start Fraction 480 Over question mark End fraction = Start Fraction 20 Over 100 End Fraction. Arrows going from 20 to 480 and from 100 to question mark are labeled times 24. 20×24=480100×24=?
Solve for the whole.
?=100×24=2400
Part over whole ( whole is your % )
7/1OO% = 4/x
cross multiply & you get 7x/7 = 4OO/7
answer is x = 57.14%
The object represented by h(t) = -4.9t² + 40t + 20 would take 4.082 seconds to reach it's maximum height.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two numbers and variables.
An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.
The height (h) is represented by:
h(t) = -4.9t² + 40t + 20
The maximum height is at h'(t) = 0, hence:
h'(t) = -9,8t + 40
-9.8t + 40 = 0
t = 4.082
The object represented by h(t) = -4.9t² + 40t + 20 would take 4.082 seconds to reach it's maximum height.
