Answer:
true
Step-by-step explanation:
we can use the Pythagorean theorem to verify if the sum of the squares built on the legs is equal to the square built on the hypotenuse
36^2 + 15^2 = 39^2
1296 + 225 = 1521
1521 = 1521
the equality is verified so the answer is true

Answers
Answer:
D
Step-by-step explanation:
D) The price was increased by 140% and then decreased by 85%.
Answer:
B

The price was only increased by 40% because for example, the starting price was 100, then if you increased it by 140% or $140, then the price would be 240.

The area of a rectangle is 42 m2, and the length is
8 m less than two times the width. Find the
dimensions of the rectangle.
Answers
Answer:
length = 14 m
width = 7 m
Step-by-step explanation:
l = length
w = width
l = 2w - 8
w(2w - 8) = 42
2w² - 8w - 42 = 0
you can factor out a 2 to work with smaller numbers:
w² - 4w - 21 = 0
(w - 7)(w + 3) = 0
w = 7
'w' cannot equal a negative so we discount it as an answer
find length:
l = 2(7) - 8
l = 14 - 8 or 6m

Answer:
f(x) = 2(4^x)
Step-by-step explanation:
Look at x = 0 in the table. It corresponds to f(x) = 2.
Now look at your answer:
f(x) = 4^x
Use x = 0:
f(0) = 4^0 = 1, but the table has f(0) = 2, so your answer is not correct.
Notice the numbers in the f(x) column. They are 2, 8, 32, 128.
Notice that they are 2 times perfect squares.
2 = 2 * 1
8 = 2 * 4
32 = 2 * 16
128 = 2 * 64
Try
f(x) = 2(4^x)
Now you have
f(0) = 2(4^0) = 2 * 1 = 2
f(1) = 2(4^1) = 2 * 4 = 8
f(2) = 2(4^2) = 2 * 16 = 32
f(3) = 2(4^3) = 2 * 64 = 128
and all the given points work.
Answer: f(x) = 2(4^x)

Suppose that a certain movie earns $3,000,000 in ticket sales. If 60% goes to the movie and 40% goes to theatres: Movie studios will get $ of the total revenue Theatres will get $ of the total revenue
Answers
Answer: See explanation
Step-by-step explanation:
Amount earned by movie = $3,000,000.
Percentage that went to movie = 60%
Percentage that went to theater = 40%
Revenue gotten by movie studio = 60% × $3,000,000
= 0.6 × $3,000,000
= $1,800,000
Revenue gotten by theaters = 40% × $3,000,000
= 0.4 × $3,000,000
= $1,200,000
