I need to determine the measure in degrees of arc BC??
Answers
ANSWER:
120°
STEP-BY-STEP EXPLANATION:
We must calculate the area of the circle, using the following formula:
[tex]\begin{gathered} A=\pi\cdot r^2 \\ \text{ replacing} \\ A=\pi\cdot9^2 \\ A=81\pi \end{gathered}[/tex]We know that this area represents 360 °, we know the area of ABC, therefore we can calculate the amount in degrees that it represents in the following way:
[tex]\begin{gathered} \frac{360}{81\pi}=\frac{x}{27\pi} \\ x=\frac{360\cdot27\pi}{81\pi} \\ x=120 \end{gathered}[/tex]Therefore, the value of arc BC is equal to the angle of area ABC, that is, the arc of BC is equal to 120°
0.16 whole number , integer, rational number (can be more than one set)
Answers
Answer : 0.16 is a rational number
Rational number is a number such that can be expressed as the quotient or fraction of two integers
An integer is a number that can be written without a fractional component
0. 16 can be written as
16 / 100
16 and 100 are both integers but 0.16 is not an integer but a rational number
16 / 100 = 0.16. This means that fraction of two integers that does does not gives an integer is a rational number
Hence, 0.16 is a ratioanal number
If you vertically compress the absolute value parent function, f(x) = lxl, by afactor of 5, what is the equation of the new function?OA. g(x) = 51x|OB. g(x)=x-51OC. g(x) = 15x|O D. g(x) = x
Answers
When the parent function f(x) = |x| is vertically compressed by a factor of 5 then we get the transformed function as g(x) = 1/5 |x| .
The given function is of the form f(x) = ·|x| .
Therefore we can say that this function will be vertically compressed.
From the properties of transformation of graphs we know that when a function is vertically compressed by a factor of a we get the transformed function as 1/a times the original function.
given function:
f(x) = |x|
vertically compressed by 5.
therefore new function = 1/5 |x|
Hence the transformed function is g(x) .
g(x) = 1/5 |x|
Let us take a few coordinates along the x-axis to get the values of the y and the graph of both modulus function pass through origin .
f(x) = |x|
at x = 10 , f(x) = 10
and g(x) = 2
Here we see that the function is compressed.
Therefore when the parent function f(x) = |x| is vertically compressed by a factor of 5 then we get the transformed function as g(x) = 1/5 |x| .

Answers
The required number would be 2 which represents "the sum of 4 times a number, and -2 is the same as the sum of five times the number, and -2."
The sum of 4 times a number, and -2 is the same as the sum of five times the number, and -2.
Let's assume the number would be x
As per the given condition, the algebraic form would be as
⇒ 4(x - 2) = 5(x - 2)
Apply the distributive property of multiplication,
⇒ 4x - 8 = 5x - 10
Rearrange the terms of variable x,
⇒ 5x - 4x = 10 - 8
Apply the subtraction operation,
⇒ x = 2
Therefore, the required number would be 2.

Find the angles using the diagram below. Line ris // to lines, and line tis I toline s.S3225045tm21= 2m22= 4m3= 5
Answers
To begin answering the question, let us familiarize ourselves with some basic terms
Linear Pairs: Two adjacent angles are a linear pair when their noncommon sides are opposite rays.
If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees.
Vertical angles: Vertical angles are a pair of opposite angles formed by intersecting lines.
Vertical angles are equal.
We can now apply this knowledege to find the required angles
To find the measure of angle 1 (m<1)
[tex]\begin{gathered} m<1\text{ and 25}^0\text{ are linear pairs} \\ so\text{ they add up to 180}^0 \\ \end{gathered}[/tex]This means that
[tex]\begin{gathered} m<1+25^0=180^0 \\ m<1=180^0-25^0 \\ m<1=155^0 \end{gathered}[/tex]Thus, m<1 = 155°
To find the measure of angle 2 (m<2)
[tex]\begin{gathered} m<2\text{ and 25}^0\text{ are vertical angles} \\ \text{This means that they are equal} \end{gathered}[/tex]Hence,
[tex]m<2=25^0[/tex]m<2 =25°
To get the measure of angle 3 (m<3)
Given: Line t is perpendicular to s
Wehen two lines are perpendicular to eachother, they meet at right angle
This means that
[tex]m<3=90^0[/tex]Thus,
m<3=90°
Hence, the summary of the solution is shown below

The mixture should be at a concentration of 65.5% to protect the cars from the coolant boiling away at 230°F .
The given table has the concentration percentages and the boiling points of the antifreeze.
So the coolant boils away at 230F, so we need to find the concertation whose boiling point is higher than 230F .
From the table it is evident that the boiling point of 236 is good to protect the coolant as it is higher and closest to the given temperature.
Corresponding to the temperature we have , the percentage at 65.5%.
As 236F > 230F , so it is evident that we need the concentration of 65.5%.

If a seed is planted, it has a 80% chance of growing into a healthy plant. If 8 seeds are planted, what is the probability that exactly 3 don't grow?
Answers
Given that a seed that is planted has an 80% chance of growing into a healthy plant, and knowing that you have to find the probability that exactly 3 seeds of 8 seeds planted don't grow, you need to use this Binomial Distribution Formula:

In this case, you can identify that:

So, from the top of the diving board to the bottom of a pool is 1,154. If we subtract this from the depth of the pool, we'll find the distance from the diving board to the surface of the pool.
So, 1,154 - 244 = 910cm. About 9 meters, 900cm.
Also, if we round each number to the nearest hundred, we'll have

The derivative of the function is given as:
[tex]g^{\prime}(x)=\frac{x^2-16}{x-2}[/tex]It is also given that g(3)=4.
Note that the Slope of a Tangent Line to a function at a point is the value of the derivative at that point.
Substitute x=3 into the derivative:
[tex]g^{\prime}(3)=\frac{3^2-16}{3-2}=\frac{9-16}{1}=\frac{-7}{1}=-7[/tex]It follows that the slope of the tangent line at x=3 is -7.
Since it is given that g(3)=4, it implies that (3,4) is a point on the line.
Recall that the equation of a line with slope m, which passes through a point (x₁,y₁) is given by the point-slope formula as:
[tex]y-y_!=m(x-x_1)[/tex]Substitute the point (x₁,y₁)=(3,4) and the slope m=-7 into the point-slope formula:
[tex]\begin{gathered} y-4=-7(x-3) \\ \Rightarrow y-4=-7x+21 \\ \Rightarrow y=-7x+21+4 \\ \Rightarrow y=-7x+25 \end{gathered}[/tex]Hence, the equation of the tangent line to the graph of g at x=3 is y=-7x+25.
The required equation is y=-7x+25.
