Ok so area is length times width. A square has the same sides all around, which is called a quadrilateral. So you would plug in 40 for length and width. 40x40= 1,600 cm^2 <———— is your answer.
Hope this helped :)
Answer:
Part A = 3 years
Part B = $3400
Step-by-step explanation:
To find this, we can model the value of the computer as V = A(.5)^x, in which x is the number of years. To find how long it takes to get to 12.5%, we can ignore all but the exponential part of the function and set equal to the percentage.
.125 = (.5)^x
3 = x
To find the initial value of the computer, use the formula created and solve for A.
V = A(.5)^x
425 = A(.5)^3
425 = A(.125)
3400 = A
Answer:
6.3feet
Step-by-step explanation:
Given data
Radius= 4feet
The expression for the circumference of a circle is
C= 2πr
Substitute
C=2*3.142*4
C=25.136 feet
Also, a 90° arc is 1/4 of the circumference of a circle
Hence the length of the 90° arc is
=25.136/4
=6.284 feet
=6.3feet
