CD bisects ∠ACB. Which statements must be true? Check all that apply.
1. AD = BD
2. AC = CD
3. m∠ACD = m∠BCD
4. m∠CDA = m∠CDB
5. m∠DCA = m∠DAC
Answer: A, C, D
Step-by-step explanation:
1) AD=BD must be true because the angle bisector drawn from the vertex angle of an isosceles triangle is the perpendicular bisector of the base.
2) AC=CD does not need to be true because angles ADC and CAD do not need to be congruent.
3) This must be true by the definition of an angle bisector.
4) This must be true because angles CDA and CDB are both right angles.
5) This does not need to be true because triangle ADC does not need to be isosceles.

A tuna can is a right circular cylinder with a radius of 4.25 centimeters and a height
of 3.25 centimeters.
a. If the volume of a cylinder is given by V = nr2h, find the volume of the can to the
nearest cubic centimeter.
Answer:
Hello, My name is Anastasiya
184.32 cubic centimeter is the volume of the can.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that A tuna can is a right circular cylinder with a radius of 4.25 centimeters.
Height of the can is 3.25 centimeters
The volume of the cylinder = πr²h
We have to substitute the values of r and h
volume of the cylinder = 3.14×4.25²×3.25
= 184.32 cubic centimeter
Hence, 184.32 cubic centimeter is the volume of the can.

If y = 3x + 1 is changed to y = 4x + 1, how would the graph of the new function compare with
the first one?
Answer:
The graph of the new function would be steeper than the first one.
Step-by-step explanation:
Slope-intercept formy= mx +c, where m is the gradient and c is the y-intercept. Note that in this form, the y term is the only term on the left-hand side of the equation and its coefficient is 1.
Identifying gradientsSince the two equations are in the slope-intercept form, we can easily identify their gradients from the coefficient of x.
The gradient of the first graph is 3, while that of the new function is 4.
Implications of a greater gradientThe gradient of a graph is how steep it is, or the change of y with respect to x. Also when we are given a linear graph without its equation, we can find its gradient using the formula:
[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]
This formula can also be written as
[tex]\boxed{ slope = \frac{rise }{run} }[/tex]
These formulas imply that the gradient is the looking at how much the y- coordinate changes with respect to x. The term 'gradient' and 'slope' have the same meaning and is used interchangeably here.
Given that the new function has a greater slope, it has a greater change in y with respect to x than the first graph. Thus, we see a steeper graph when y= 3x +1 is changed to y= 4x +1.
y- interceptsThe y-intercept does not change in this case and both graphs intercept the y-axis at y= 1.
NoteIn the attached graph, the first graph is represented by the red line while the graph of the new function is in blue.
One of the giraffes, Bernard, is sick. Last week he weighed 2,490 pounds. This week, he weighs 2,312 pounds.
If w represents the amount of weight lost, which bar diagram can be used to find the amount of weight Bernard lost?
Answer:
w+2,312=2,490
w= 178 pounds
Step-by-step explanation:
Let
W—-^ the amount of weight Bernard lost in pounds
We know that
The amount of weight Bernard lost plus the weight of this week must be equal to the weight of the last week
So…
The linear equation that represents this situation is
w=2,312=2,490
solve for w
Subtract 2,490 - 2,312 = 178lbs

find the second derivative of the given function.
[tex]f(x) = \frac{x {}^{2} + 2x - 1}{ x} [/tex]
Answer:
= -2/x^3
Step-by-step explanation:
Possible derivation:
d/dx(d/dx((x^2 + 2 x - 1)/x))
Distribute 1/x through x^2 + 2 x - 1:
= d/dx((d/dx(2 - 1/x + x)))
Differentiate the sum term by term and factor out constants:
= d/dx((d/dx(2) - d/dx(1/x) + d/dx(x)))
The derivative of 2 is zero:
= d/dx(0 - d/dx(1/x) + d/dx(x))
Use the power rule, d/dx(x^n) = n x^(n - 1), where n = -1.
d/dx(1/x) = d/dx(x^(-1)) = -x^(-2):
= d/dx(0 - -1/x^2 + d/dx(x))
The derivative of x is 1:
= d/dx(0 - -1/x^2 + 1)
Differentiate the sum term by term:
= d/dx(1) + d/dx(1/x^2)
The derivative of 1 is zero:
= d/dx(1/x^2) + 0
Simplify the expression:
= d/dx(1/x^2)
Use the power rule, d/dx(x^n) = n x^(n - 1), where n = -2.
d/dx(1/x^2) = d/dx(x^(-2)) = -2 x^(-3):
Answer: = -2/x^3

rahim's father's age is 3 times as old as him. if their sum is 56 , find their ages
Answer:
Rahim is 14 and his father is 42.
Step-by-step explanation:
Let F be Rahim's father's age and R is Rahim's age.
We learn that:
F = 3R [Rahim's father's age is 3 times as old as him]
and
F + R = 56 [their sum is 56]
----
We have 2 equations and two unknowns, so we should be able to find the answers.
Rearrange the second equation to: F = 56 - R
The use that definition of F in the first equation:
F = 3R
(56-R) = 3R
Then we can find R:
56-R = 3R
4R = 56
R = 14
Since R=14 and F + R = 56,
F + R = 56
F + 14 = 56
F = 42
Check
Does F=3R?
42 = 3(14)? YES
Does F + R = 56?
42 + 14 = 56? YES
Rahim is 14 and his father is 42.

Answer:
It will take 12.5 days for Alejandra to catch up with Javier and they both will have travelled 800m
Step-by-step explanation:
Alejandra "catching up" implies that they will both have travelled the same distance
Therefore,
Let y represent the distance when Alejandra will catch up with Javier
Since both equations have the same y-value (distance):
24x+500 = 12x+650
24x - 12x = 650 - 500
12x = 150
x = 12.5
It will take 12.5 days for Alejandra to catch up with Javier
Next, put the amount of time into any of the 2 equations to find what the distance is:
24x + 500 = y
24 (12.5) + 500 = y
y = 800
800m is the distance travelled when Alejandra catches up with Javier

f(x)=2x−2
g(x) = −2x + 1
Find f(5) • g(3)
Answer:
-40
Step-by-step explanation:
Given function: f(x) = 2x - 2
f(5) means: substitute x = 5 into the function:
⇒ f(5) = 2(5) - 2
⇒ f(5) = 10 - 2
⇒ f(5) = 8
Given function: g(x) = -2x + 1
g(3) means: substitute x = 3 into the function:
⇒ g(3) = -2(3) + 1
⇒ g(3) = -6 + 1
⇒ g(3) = -5
Therefore,
f(5) · g(3) = 8 · -5 = -40
f(5):-
[tex]\\ \rm\rightarrowtail 2(5)-2[/tex]
[tex]\\ \rm\rightarrowtail 10-2[/tex]
[tex]\\ \rm\rightarrowtail 8[/tex]
g(3)
[tex]\\ \rm\rightarrowtail -2(3)+1[/tex]
[tex]\\ \rm\rightarrowtail -6+1[/tex]
[tex]\\ \rm\rightarrowtail -5[/tex]
So
f(5)g(3)=8(-5)=-40

The two figures below are similar. What is
the length of side GH?
help asap!
Answer: A. 3 units
Step-by-step explanation:
Since the two figures are similar, that means their side lengths are proportional.
Therefore, [tex]\frac{CB}{KF} = \frac{EA}{GH}[/tex].
We are given the value for 3 of these side lengths.
Thus, [tex]\frac{10}{5} = \frac{6}{GH}[/tex].
We can cross multiply:
10 GH = 30
Divide both sides by 10:
GH = 3 units
The assumption that there are no exact linear relationships among the independent variables in a multiple linear regression model fails if _____, where n is the sample size and k is the number of parameters.
a. n < k 1
b. n > k
c. n
Answer:
a. n < k + 1
Step-by-step explanation:
Multiple linear regression model is used for analyzing the linear relationship between the independent variables and dependent variable. It is used when there is the need to predict the relationship of a variable based on the values of two or more other variables. These variables could be nominal, ordinal, or interval/ratio level variables.
Some assumptions of multiple linear regression analysis are:
i. There must be a linear relationship between the outcome variable and the independent variables.
ii. The residuals are normally distributed.
iii. That the independent variables are not highly correlated with each other.
The assumption that there are no exact linear relationships among the independent variables in a multiple linear regression model fails if n < k + 1.
