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.

if 4-3(2-x)<10+x what is the greatest possible integer value of x?
Answer:
4-3(2-x) < 10+x
4 -6 +3x< 10 + x
-2 +3x< 10 +x
2x< 12
x<6
↣ First we solve the Inequality.
[tex]4-3(2-x)<10+x[/tex]
[tex]4-6+3x<10+x[/tex] ↣ Distribute -3 in (2-x) for easier in solving.
[tex]3x-2<10+x\\3x-x<10+2\\2x<12\\x<6[/tex]
Thus, the answer is x < 6.

The first side of a triangle measures 5 in. less than the second side, the third side is 3 in. more than the first side, and the
perimeter is 17 in. How long is the third side?
If s represents the length of the second side, which of the following represents the length of the third side?
s-5
S-2
s+3
Answer:
see explanation
Step-by-step explanation:
let s be the second side then the first side is s - 5 and the third side is
s - 5 + 3 = s - 2
-------------------------
the perimeter (P) is the sum of the 3 sides of the triangle.
given P = 17 , then
s - 5 + s + s - 2 = 17
3s - 7 = 17 ( add 7 to both sides )
3s = 24 ( divide both sides by 3 )
s = 8
third side = s - 2 = 8 - 2 = 6 in

The domain on which the following function is increasing
The domain on which of the following function is increasing is [0,4].
Given:
The graph of a function.
To find:
The domain on which of the following function is increasing.
Domain is the set of x-values or input values.
From the given graph it is clear that the vertex of the given function is at (4,75).
Before the point (4,75) the graph is increasing and after the point (4,75) the graph is decreasing.
The function is defined for 0≤x≤9 .
Since the graph is increasing when 0≤x≤4 , therefore the function is increasing over the interval [0,4].
Therefore, the domain on which of the following function is increasing is [0,4].
What is domain?
The domain is the value that x can take from a given function and codomain is the value of y from a function.

Step-by-step explanation:
4) The speed of light is 3 x 10^8 meters per second. The distance to the
sun is 1.5 x 10^11 meters. How long does it take light to reach the Earth
from the Sun. 0.5 seconds
5 seconds
50 seconds
500 seconds
Answer:
500 seconds
Step-by-step explanation:
This is a distance = rate × time problem
d = 1.5 × 10^11 m
rate = 3 × 10^8 m/s
So, d = rate × t
t = d ÷ rate = 1.5 × 10^11 m ÷ 3 × 10^8 m/s = 500 s

Answer:
B: 22.5 degrees
Step-by-step explanation:
The interior angles of a pentagon add up to 540 degrees
(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)
So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60
Unless I read the problem wrong, 60 degrees is the answer which is not an option :P
Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.
The total would be 24x = 540, and so x = 22.5

Grant spent half of his weekly allowance. Then he earned $5 back by doing the dishes. What is his weekly allowance if he ended with $15?
Answer:
Grant's weekly allowance is $20.
Step-by-step explanation:
We know that Grant ended with $15. We can say that Grant's weekly allowance is x.
x/2 + 5 = 15
Now to solve:
x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)
x/2 = 10
x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)
x = 20
Grant's weekly allowance is $20.
