Which monomial function has a maximum value?
(Can anyone explain how you can tell?)
y=-6x^3
y=-5x^4
y=5x^6
y=6x^5,
Answers
To determine which of the following monomial function has a maximum value, you have to assume the value of x. Let us say the value of x is 2. Substitute 2 for all x’s in the monomial function.
y=-6x^3 = -6(2)^3 = -48y=-5x^4 = -5(2)^4 = -80
y=5x^6 = 5(2)^6 = 320
y=6x^5 = 6(2)^5 = 192 Therefore, the monomial function with the maximum value is y = 5x^6
Answer:
[tex]y=-5x^4[/tex]
Step-by-step explanation:
Remember that a maximum value (global) of a function is the bigest value that the function takes.
For see the values of the functions you can see its graphs.
I have uploaded the graphs of the functions in the question and you can see it, and then convince yourself why the answer is y=-5x^4.
Also you have the fact that the functions of the form [tex]y=kx^n [/tex] have a maximum value only if [tex]n[/tex] is an even natural number and k is a negative real number.

A. A savings bond
B. A money market account
C. A certificate of deposit
D. A basic savings account
@soccerman,
Answers
D) a basic savings account.
Explanation:
Liquidity means ability to withdraw your money quickly.
A savings bond takes time, often years, to mature.
A money market account is fairly liquid, although it can take up to 7 days to withdraw your money.
A certificate of deposit (CD) can be easily withdrawn, but you will lost interest if you do not fulfill the entire term of the CD.
With a basic savings account, you can withdraw money at any time; however you may experience fees for not having met the minimum balance requirements if you're not careful.

The answer to your question is " A function can have several y-intercepts". This statement is not true.
The following are true:
-
Every function can be represented by a graph in the Cartesian plane.
-
Another name for an x-intercept is a real zero.
and
A function can have infinitely many x-intercepts.
Final answer:
Option "C."
Hope this helps you.
Have a great day!
Final answer:
The statement that is NOT true is that a function can have several y-intercepts.
Explanation:
NOT true statement: C. A function can have several y-intercepts.
In a Cartesian plane, a function typically has only one y-intercept, where it crosses the y-axis.
A y-intercept represents the point where the function intersects the y-axis, indicating the value of the function when the input is zero.

If PX = 25, find PQ

not 100% sure how to figure this out
Answers
PZ = ZR ... (Equation 1)
QY = YR ... (Equation 2)
PX = XQ ... (Equation 3)
QUESTION 1
If PX = 25, find PQ
From the diagram, PQ = PX + XQ
Remember, PX = XQ ... (Equation 3)
Therefore, PQ = PX + XQ = PX + PX
⇒ PQ = PX + PX
PQ = 2(PX)
Since PX = 25
PQ - 2(25)
PQ = 50
QUESTION 2
If CY = 9, find PC and PY
We know that the centroid of a triangle divides each median into segments with a 2:1 ratio, therefore:
PC = 2(CY)
Since CY = 9,
PC = 2(9)
PC = 18
From the diagram, we see that,
PY = PC + CY
PC = 18, CY = 9
PY = 18 + 9
PY = 27
QUESTION 3
If QC = 12, find ZC and ZQ
Again, going by the fact that the centroid of a triangle divides each median into segments with a 2:1 ratio,
ZC = QC/2
Since QC = 12
ZC = 12/2
ZC = 6
From the diagram, we see that
ZQ = ZC + QC
ZC = 6, QC = 12
ZQ = 6 + 12
ZQ = 18

Victor will borrow $6800 at 13.5% APR. He will pay it back over 3 years. What will his monthly payment be?
$156.47
$227.46
$230.79
$324.90
Answers
Hope this helped!
Final answer:
Victor's monthly payment for the $6800 loan at 13.5% APR over 3 years is approximately $227.46.
Explanation:
To calculate Victor's monthly payment for a loan of $6800 at an APR of 13.5% over 3 years, we need to first convert the annual rate to a monthly interest rate. This is done by dividing the APR by 12 (months in a year). So, the monthly interest rate is 13.5% divided by 12, which is approximately 1.125% per month or 0.01125 in decimal form.
Next, we use the formula for an amortizing loan payment:
P = (Pv*r) / (1 - (1+r)⁻ⁿ)
Where P is the monthly payment, PV is the present value or the amount of the loan, r is the monthly interest rate in decimal form, and n is the total number of payments (months).
For Victor's loan, we have:
Present Value (PV) = $6800
Monthly Interest Rate (r) = 0.01125
Total Number of Payments (n) = 3 years * 12 months/year = 36 months
Substituting the given values into the formula yields:
P = ($6800 * 0.01125) / (1 - (1+0.01125)⁻³⁶)
Calculating the above expression, we find that Victor's monthly payment is approximately $227.46, which is one of the options given.

From 1980 to 1990, the consumer price index (CPI) increased from 82.4 to 130.7. If a gallon of apple juice cost $0.95 in 1980 and the price of apple juice increased at the same rate as the CPI from 1980 to 1990, approximately how much did a gallon of apple juice cost in 1990?
A. $0.56
B. $0.82
C. $1.51
D. $1.31
Answers
To solve this, start with a proportion. Put the CPI numbers on the left and the apple juice prices on the right.
You will have:
82.4/130.7 = 0.95/x
Cross multiply to solve and you will get the price of the juice is $1.51.
Answer:
The cost of the gallon of the apple juice is approximately $1.51 in 1990. (Option C)
Step-by-step explanation:
As it can be assumed that the increase of the gallon of apple juice is proportional to the increase of the CPI, we can state that the rate of the price of 1990 to the price of 1980 is the same than the rate of the CPI in 1990 to the CPI in 1980:
$130.7 / $82.4 = Pg (1990)/ $0.95
Where Pg (1990) is the apple juice gallon cost for 1990. By solving the equation above:
$130.7 / $82.4 * $0.95 = Pg (1990)
Pg (1990) = $1.5068 ---> Pg (1990) = $1.51

m∠P = 78
answer
m∠P = 78
Answer:
[tex]m\angle P=12^{\circ}[/tex]
Step-by-step explanation:
Two triangles are similar if their angles are equal one to one.
So:
[tex]m\angle P= m\angle S\\m\angle Q= m\angle T\\m\angle R= m\angle U[/tex]
Also, the problem provided this data:
[tex]m\angle T= 6(m\angle P)[/tex]
As you may know, the sum of the interior angles of a triangle is equal to 180, so:
[tex]m\angle S+m\angle T + m\angle U=180\\\\Where:\\\\m\angle T=6(m\angle P)\\\\So:\\\\m\angle S+6(m\angle P) + m\angle U=180[/tex]
and:
[tex]m\angle P=m\angle S\\\\Hence\\\\m\angle S+6(m\angle S) + m\angle U=180\\\\7(m\angle S) + m\angle U=180\\\\7(m\angle S) + 96=180[/tex]
Solving for [tex]m\angle S[/tex]
[tex]m\angle S =\frac{180-96}{7} =12^{\circ}[/tex]
Since:
[tex]m\angle P= m\angle S=12^{\circ}[/tex]
Therefore [tex]m\angle P=12^{\circ}[/tex]

Minimum value=7
and Maximum value=12
Range=Maximum value-Minimum value
This means that Range is: 12-7=5

Sun Plant heights (in.)

Also, the mean is calculated as follows:
[tex]Mean=\dfrac{21+24+19+19+22+23+24+24}{8}\\\\\\Mean=\dfrac{176}{8}\\\\\\Mean=22[/tex]
Difference in mean is: 22-10=12
Also, the range of both the set is: 5
Hence, the difference in mean could be expressed as:
12=5×n
Hence, n=2.5
The expression (12 = 5×2.4) represents the difference in the means as a multiple of their ranges if the mean for the first data set is 10 and for the second data set is 22.
What is mean?It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
For the first data:
The mean can be calculated as follows:
[tex]\rm Mean = \frac{\sum x}{n}[/tex]
[tex]\rm Mean = \frac{7 + 11+ 11+ 12 + 9+ 12+ 8+ 10}{8}[/tex]
Mean(1st data set) = 10
For range:
The minimum value in the data set = 7
The maximum value in the data set = 12
Range = 12 - 7 ⇒ 5
For the second data set:
The mean can be calculated as follows:
[tex]\rm Mean = \frac{\sum x}{n}[/tex]
[tex]\rm Mean = \frac{21 + 24 + 19 + 19 + 22 + 23 + 24 + 24}{8}[/tex]
Mean(2nd data set) = 22
For range:
The minimum value in the data set = 19
The maximum value in the data set = 24
Range = 24- 19 ⇒ 5
Difference in means = 22 - 10 ⇒ 12
Since the range is the same for both the data set.
From the problem:
12 = 5×n
n = 2.4
Thus, the expression (12 = 5×2.4) represents the difference in the means as a multiple of their ranges if the mean for the first data set is 10 and for the second data set is 22.

The best answer for this question would be:
D. 32
In order to get this, you have to get the sum in the line, which is the first four people. So the solution would be: 4(23) = 92
For getting the sum of the people in the last 3 would be: 3(34) = 102
Next is the sum of everyone which the solution would be: 6(27) = 162
So the initial solution that we have now would be: F + 92 - F + 102- F = 162
- F + 194 = 162
- F = 162 - 194
- F = - 32
The (F) here or the fourth person’s age would be= -32 / - 1 or 32
