1/5 of 30 is 6.
There are 6 red circles
Answer: The percentage increase in perimeter is 7%.
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length + width)
The original length of the rectangle is 20 and the original width is 30. The original perimeter of the rectangle would be
Perimeter = 2(20 + 30) = 100
The length of the rectangle is increased by 10 percent. It means that the new length would be
20 + (0.1 × 20) = 22
The width of the rectangle is increased by 5 percent. It means that the new width would be
30 + (0.05 × 30) = 31.5
The new perimeter of the rectangle would be
Perimeter = 2(22 + 31.5) = 107
The increase in perimeter is
107 - 100 = 7
The percentage increase in perimeter is
7/100 × 100 = 7%
Pretty low, it’s exactly 0.175
Answer: its 4/-2
Step-by-step explanation: the rise of the line is 4 up and the run of the line is -2
The given data are:
A function that:
The domain is the set of all real numbers
One x-intercept
The amplitude is 4
The y-intercept is (0,0)
From the choices, the functions containing "cosine" can be eliminated since the described function passes through (0,0). So, we are left with two choices:
y = -4sin (x) and y = 4sin (x)
Given the amplitude of 4, the answer must be y = 4 sin(x)
