Let's simplify step-by-step.
5x^3 + 3 + 2x^3 − x^2 + 1
= 5x^3 + 3 + 2x^3 + −x^2 + 1
Combine Like Terms:
= 5x^3 + 3 + 2x^3 + −x^2 + 1
= ( 5x^3 + 2x^3 ) + ( −x^2 ) + ( 3 + 1 )

Given:BK=CH Which additional congruence statement could you use to prove that ∆BJK ≅ ∆CFH by the HL Theorem?
Answer:
B
Step-by-step explanation:
The hl theorem says that if we have two right triangles that have a congruent hypotenuse and a congruent leg, the two triangles are congruent
in this case the exercise says the two leg are congruent, so we have to say that the two hypotenuse are congruent
So
JB congruent to FC

A. the control group in an experiment
B. the experimental group in a survey study
C. the experimental group in an experiment
D. the control group in an observational study
Answer:
A. the control group in an experiment
Step-by-step explanation:
Researchers give one group a new cold medicine and compare them with to a group that takes no medicine. The group that is not given any medicine is the control group in an experiment.
Who are researchers?Researchers are those who do research on something i.e. systematics and deep investigation into something.
What is control group?Control Group is that group in research which does not take any medication or untreated group.
During the research while a new type of medicine is to be tested, the group that receives the medication or being tested is called the experimented group and the group that does not receive the treatment is called the control group.
Hence, we can say that the group that is not given any medicine is the control group in an experiment.

Answer:
m1= 82
m2=98
m3=82
Step-by-step explanation:
Angle m4 is supplementary with angle m1 so their values add up to 180
180-98=82
Angle m3 is opposite of m1 and is the same value, it is also supplementary to m4 so you can find the value that way as well.
Angle m3 is opposite of m4 so it is the same value. It is supplementary to m1 and m3, so it must be 98 through that logic as well.

The sum of three consecutive numbers is 72. What is the smallest of these numbers? Set up an equation to solve.
Answer:
Let the three consecutive numbers be x,x+1,x+2 . The numbers are: 23,24,and25 and the smallest one is 23
Step-by-step explanation:
Answer: (x-1) + (x) + (x+1) = 72; smallest number is 23.
Step-by-step explanation:
The numbers are consecutive, meaning they sit next to each other on a number line. For example 4, 5, 6.
Because they are three consecutive numbers, their average will be the value of the middle one. For example the average of 4, 5, 6 is 5.
Knowing this, we can divide 72 by three to get the value of the middle number.
72/3 = 24, so the middle number is 24.
The numbers that fall either side of 24 on the number line are 23 and 25, so the three consecutive numbers are 23, 24, 25.
You can also set up and solve the equation: (x-1) + (x) + (x+1) = 72 because the numbers are consecutive.
To solve, combine like terms. The (-1) and (+1) cancel out and the equation becomes 3x = 72.
72/3 = 24, so x = 24, and the smallest term, (x-1) = 23.

A dilation by scale factor then a translation of
4 units up.
Answer:
A reflection in the line y = -2, then a translation 2 units right.
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Rigid transformation are transformation that preserves the shape and size of the object. Rotation, reflection, translation are rigid transformation whereas dilation is not a rigid transformation.
Any transformation regarding dilation changes the side length of the object and hence the area.
From the question, only one option is right. The rest options are not right because they involve dilation. The correct option is:
A reflection in the line y = -2, then a translation 2 units right.

SATISFY THE MISSING VALUE, X, IN EACH DIAGRAM.
A company models its net income, in thousands of dollars, with the function f(x)=9x2−54x−144 , where x is the number of units of its product sold. How many units of its product does the company need to sell in order for the net income to equal $0?
The company needs to sell 8 units in order for the net income to equal $0
The net income function is given as:
[tex]f(x) = 9x^2 - 54x - 144[/tex]
When the net income is 0, then f(x) = 0.
So, we have:
[tex]9x^2 - 54x - 144 = 0[/tex]
Divide through by 9
[tex]x^2 - 6x - 16 = 0[/tex]
Expand the above equation
[tex]x^2 +2x- 8x - 16 = 0[/tex]
Factorize the above equation
[tex]x(x +2)- 8(x + 2) = 0[/tex]
Factor out x + 2 in the above equation
[tex](x - 8)(x + 2) = 0[/tex]
Split and solve for x
[tex]x = 8[/tex] or [tex]x =-2[/tex]
The units of product cannot be negative.
So, the value of x is [tex]x = 8[/tex]
Hence, the company needs to sell 8 units

Given:
The figure of a circle.
To find:
The measure of arc AD and measure of each arc.
Solution:
The measure of arc is equal to the central angle of that arc.
The central angle of arc AD is 105 degrees. So,
[tex]m(arc(AD))=105^\circ[/tex]
The central angle of arc BC is 35 degrees. So,
[tex]m(arc(BC))=35^\circ[/tex]
The central angle of arc CD is 50 degrees. So,
[tex]m(arc(CD))=50^\circ[/tex]
The central angle of a complete circle is 360 degrees. So,
[tex]m(arc(AD))+m(arc(BC))+m(arc(CD))+m(arc(AB))=360^\circ[/tex]
[tex]105^\circ+35^\circ+50^\circ+m(arc(AB))=360^\circ[/tex]
[tex]190^\circ+m(arc(AB))=360^\circ[/tex]
[tex]m(arc(AB))=360^\circ-190^\circ[/tex]
[tex]m(arc(AB))=170^\circ[/tex]
Therefore, the measure of arc AD is 105°, the measure of arc BC is 35°, the measure of arc CD is 50° and the measure of arc AB is 170°

According to a soccer coach, 75% of soccer players have had at least one sprained ankle. An athletic trainer would like to investigate this claim. To do so, the trainer selects a random sample of 125 college soccer players from across the country and finds that 99 of them have had at least one sprained ankle. The trainer would like to know if the data provide convincing evidence that the true proportion of college soccer players who have had at least one sprained ankle is greater than 75%. What are the appropriate hypotheses for this test
The appropriate hypotheses for this test are
p = 0.75 for Null Hypothesis.
p > 0.75 for Alternative Hypothesis.
Given that,
According to a soccer coach, 75% of soccer players have had at least one sprained ankle.
Null Hypothesis (H₀):
The true proportion of college soccer players who have had at least one sprained ankle is equal to 75% is,
p = 0.75
Alternative Hypothesis (Ha):
The true proportion of college soccer players who have had at least one sprained ankle is greater than 75%.
p > 0.75
Here, We are testing if the true proportion is greater than 75%, so the alternative hypothesis should reflect that.
The null hypothesis assumes the proportion is equal to 75%.
