Answer:
The sides are 5,18,16
Step-by-step explanation:
To find the perimeter of a triangle, we add up all the sides
n +4n-2 + 5n-9 = 39
Combine like terms
10n -11 = 39
Add 11 to each side
10n-11+11 = 39+11
10n = 50
Divide by 10
10n/10 =50/10
n = 5
Now we need to find each side
n = 5
4n-2 = 4(5)-2 = 20-2 =18
5n-9 = 5(5) - =25-9 = 16
The sides are 5,18,16
The formula we use for continuous compounding is
where P is the initial amount invested, r is the rate as a decimal, and t is time in years. Our P = 1300, our r = .042, and our t = 5.75 (9 months is 3/4 of a year, and 3/4 in a decimal is .75). Putting all that into our formula we have
. We have to multiply those 2 powers together and then raise euler's number to it, then multiply by 1300. Doing all of that, we get the amount at the end to be $1,655.10
Q.1A.). Tim has a scale model of an airplane which says it is in a 1:15 ratio what shoes that mean? Answer: It means that the scale model of the Airplane; Tim has is 15 times smaller than it's real size.
Q.2B.). If a scale factor is LESS than one, then the object will scale REDUCTION or WRITTEN as a FRACTION; bigger to smaller dimensions.
Q.3C.). If a scale factor is GREATER than one, then the object will scale A SKETCH; to larger dimensions.
Summary: A scale factor describes how much larger; or smaller; The enlarged shape is compared to the original shape.
• A description of a dilation includes the scale factor (or ratio) and the center of the dilation.
• The center of dilation is a fixed point in the plane.
• If the scale factor is greater than 1, the image is an enlargement (a stretch).
• If the scale factor is between 0 and 1, the image is a reduction (a shrink).
• If the scale factor is 1, the figure and the image are congruent.
