Consider the polar curve r = 4sin(2θ). What is the length of each petal, and how many petals does the graph have?
a.The length of each petal is 2, and the number of petals is 2.
b.The length of each petal is 2, and the number of petals is 4.
c.The length of each petal is 4, and the number of petals is 2.
d.The length of each petal is 4, and the number of petals is 4.
Answer:
The length of each pearl is a given r= a cos(n 0) the answer is 4 and number of petals is 4 (I think )
Step-by-step explanation:
The length of the petal and number of petals of the rose curve is required.
The correct option is d.
The given curve is
[tex]r=4\sin(2\theta)[/tex]
The general equation of a rose curve is
[tex]r=a\sin(n\theta)[/tex]
where
a = Length of petal
n = Number of petals if [tex]n[/tex] is odd
and [tex]2n[/tex] if [tex]n[/tex] is even.
So, here
[tex]a=4[/tex]
[tex]n=2n=2\times 2=4[/tex]
So, length of each petal is 4 and the number of petals is 4.

Don has two jobs. For Job 1, he earns $7.55 an hour. For Job 2, he earns $8.45 an hour. Last week he worked at the first job for 10 hours and at the second job for 15 hours. What were his average earnings per hour? a $8.15 b $8.13 c $8.00 d $8.09
Answer:
D. $8.09
Step-by-step explanation:
Get the total amount for Job 1 & Job 2 he worked for x amount of hours. The x amount of hours and the amount of earnings he get per hour is given to us:
Job 1: $7.55 x 10 = $75.50
Job 2: $8.45 x 15 = $126.75
Add two total costs from work:
$75.50 + $126.75 = $202.25
You add 10 + 15 to get 25 and we need this number for the average as he worked 25 hours in total:
$202.25 / 25 = $8.09 per hour
Don's average earnings per hour is $8.09 per hour.

Which equation shows
y = 3x - 1/5
in standard form?
I will mark brainliest!!
Answer:
15x-5y=1
Step-by-step explanation:
y=3x−15
The standard form of a linear equation is Ax+By=C.
Multiply both sides by 5.
5y=5(3x−15)
Simplify 5(3x−15).
5y=15x−1
Rewrite the equation with the sides flipped.
15x−1=5y
Move all terms containing variables to the left side of the equation.
15x−5y−1=0
Add 1 to both sides of the equation.
15x−5y=1

Using a layaway plan, Bill bought a set of golf clubs for $1700. He has 6 months to pay off his balance after paying a down payment. The store does not charge a fee for their program. If Bill makes payments of $201 a month, how much did he need to use as a down payment in order to pay for the clubs
Answer:
$494
Step-by-step explanation:
Given that:
Cost of golf club = $1700
Number of months taken to balance payment after down payment = 6 months
Amount paid per month = $201
The down payment made :
Cost of golf clubs - (monthly payment * number of months)
$1700 - ($201 * 6)
$1700 - $1206
= $494
Hence, the downpayment made = $494

use the function g (x) = √x-5 for the problem below which is what are the values of x for which g(x)=6?
Answer:
x = 121
Step-by-step explanation:
We are given;
g(x) = √x - 5
Now, we are told that g(x) = 6
Thus;
√x - 5 = 6
Add 5 to both sides to get;
√x = 11
Square both sides to get;
x = 121

Molly increased her original score as a bowler by 20% giving her a new score of 75. What was her original score?
Answer:
62.5
Step-by-step explanation:
120% = 75
100% = ?
cross multiply
62.5
Her original score was 62.5
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here, her new score as 75 then let his original score be x
then 75 = (1+20%) × x
x= 75/1.2
= 62.5
Hence, the original score is 62.5
