Violent Crimes The function V(t) = 5.062 - 87.3t + 1761.1
models the number V (in thousands) of violent crimes com-
mitted in the United States t years after 1995, based on data
obtained from the Federal Bureau of Investigation. Sot = 0
represents 1995,
= 1 represents 1996, and so on.
(a) Determine the year in which the fewest violent crimes
were committed.
(b) Approximately how many violent crimes were commit-
ted during this year?
(c) Using a graphing utility, graph V = V(t). Were the num-
ber of violent crimes increasing or decreasing during the
years 1995 to 2003?

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

umm im not really sure because i never had to do this
