8.A golfer swings a club about a pivot point. If the head of the club travels a distance of 26 feet and rotates through an angle of 5 radians, which of the following gives the distance the club head is from the pivot point?
The distance the club head is from the pivot point is about 5.2 feet.
What is a circle?A circle is the locus of a point such that its distance from a fixed point known as the center is always constant.
Let r represent the radius of the circle, that is the distance the club head is from the pivot point. Hence:
Length of arc = angle in radians * radius
26 = 5r
r = 5.2 feet
The distance the club head is from the pivot point is about 5.2 feet.

Priya is mixing drops of food coloring to create purple frosting for a cake she uses 24 drops of red dye and 16 drops of blue dye find the ratio of drops of red dye to total drops of dye
Answer:
24:40
Step-by-step explanation:
To find the radio for red dye to total drops of dye, just add the red and blue dye.
The ratio of drops of red dye to total drops of dye is 3:2.
What is Ratio?When a number is divisible by another number, then it can be written in the form of a:b, this is called Ratio.
Priya is making frosting.
The number of drops of blue dye is 16.
The number of drops of red dye is 24.
Ratio ( Red dye : Blue dye) = 24 : 16
Ratio ( Red dye : Blue dye) = 3:2

Since -2 is in between -5 and 0, we will use the part of the function that says f(x)=x^2 + 3x.
Substituting x=-2, we get (-2)^2 -3(-2)=4+6=10
Please help asap! I will gave brainlest!
Step-by-step explanation:
I know that
[tex] \cot {}^{2} (x) + 1 = \csc {}^{2} (x) [/tex]
So These the steps I need to do:
First Apply Reciprocal Identies to find Cot x.
[tex] \frac{1}{ \tan(x) } = \cot(x) [/tex]
So cot x is
[tex] \frac{24}{7} [/tex]
Now, I can squared that result and add 1 to get csc^2(x).
[tex] \frac{576}{49} + 1 = \frac{576}{49} + \frac{49}{49} = \frac{625}{49} [/tex]
Now, I take the principal square root since csc is positve when theta is in the 1st quadrant.
[tex] \frac{ \sqrt{625} }{ \sqrt{49} } = \frac{25}{7} [/tex]
So
[tex] \csc(x) = \frac{25}{7} [/tex]
[tex]cosec{\theta=\frac{25}{7}is\ the\ answer.}[/tex]
Step-by-step explanation:[tex]If\ tan\ \theta=\frac{7}{24},0\ degrees < \theta < 90\ degrees[/tex]
[tex]sec\ \theta=\sqrt{1+\tan^2\theta}=\sqrt{1+\frac{49}{576}}=\sqrt{\frac{625}{576}}=\frac{25}{24}[/tex]
[tex]cos\ \theta=\frac{1}{sec\ \theta}=\frac{24}{25}[/tex]
[tex]sin\ \theta=\sqrt{1-\cos^2\theta}=\sqrt{1-(\frac{24}{25})^2}=\sqrt{\frac{49}{625}}=\frac{7}{25}[/tex]
[tex]cosec\ \theta=\frac{1}{sin\ \theta}=\frac{25}{7}[/tex]
[tex]Hence,\ cosec\ \theta=\frac{25}{7}is\ the\ answer.[/tex]

For what values of a are the following expressions true?
1. |a-5|=5-a
2.|a|=-a
Answer:
1. a = 0 and 5
2. no solutions
Step-by-step explanation:
For absolute value, it's the distance from that number on the number line to 0, so it has to be positive. We define absolute value as when |a| = b, a = b and a = -b.
1. |a - 5| = 5 - a
a - 5 = 5 - a
2a = 10
a = 5
AND
a - 5 = -(5 - a)
a - 5 = -5 + a
-5 = -5
a = 0 (a could work as 0 in this scenario)
Thus our solutions are a = 0 and 5.
2. |a| = -1
Now we have to catch ourselves here. Since absolute value is always positive, nothing works. There is no negative distance to 0 (at least in real numbers). Hence, we can say that there are no solutions.
What is the image point of (1,-2)(1,−2) after a translation right 4 units and down 4 units?
Answer:
(-3, 2)
Step-by-step explanation:
If we are dealing with vertical movement up/down, we manipulate the x-axis.
If we are dealing with horizontal movement left/right, we manipulate the y-axis.
We are trying to move the point right 4 units (horizontal movement) and down 4 units (vertical movement).
(1, -2) → (1 - 4, -2 + 4) → (-3, 2)

In the year 2000, the height of an apple tree was
150 centimeters. In the year 2020, the same tree has
grown to 270 centimeters. What was the average rate
of change in the height of the tree from 2000 to 2020?
In other words: On average, how fast was the tree
growing? Include units.
Answer:
(270+150)/(2020-2000)= 21 - average rate of change in the height per year
Answer:
I think to get the average rate you subtract 150 from 270 centimetres you'll get 120 centimetres then subtract 2000 from 2020 to get 20 now to get the rate divide 120cm by 20 and you will get six so the rate is 6 cm per year

Artichokes were on sale. Five of them cost $1. At this rate, what would be the price for a dozen artichokes?
Group of answer choices
$2.52
$2.50
$2.40
Answer:
$2.40
Step-by-step explanation:
as five of artichokes caused $1, a dozen is the same number as 12, so use cross multiply and you will get the answer $2.40
cross multiply : 5 artichokes = $1
12 artichokes = x
5x = $1 x $12
5x = $12
x = 12/5
x = $2.40

What is x in this figure?
Answer: x=36
Assuming that O is the centre of the circle,
108+a+a=180(sum of the interior angles of a triangle is 180)
2a=180-108
2a=72
a=72÷2
a=36
a=x (angles in the same segment are equal)
Therefore x=36
