If f(x) = 3x-2 what is the value of 5
A. 9
B. 13
C. 15
D. 33
B
Assuming you mean the value of f(5)
If so then substitute x = 5 into f(x)
f(5) = (3 × 5) - 2 = 15 - 2 = 13 → B
im terrible with graphs help me out...but explain it cuz im a math inclined typa person sooo.......idek just help i guess?
Answer:
14. The correct option is 2.
13. The correct option is 4.
Step-by-step explanation:
14.
The given function is
[tex]f(x)=4|x|[/tex]
The function is non-negative for all values of x. So, the function opens in upward direction.
The function uis in the form of
[tex]f(x)=k|x|[/tex]
Where, a is vertical stretch factor or compress factor.
If k>1, then it represent vertical stretch and if 0<k<1, then it represent vertical compression.
Since the value of k is 4, therefore it represents vertical stretch and option 2 is correct.
13.
The given function is
[tex]y=x^3[/tex]
The traslate form of given function is
[tex]y=(x+a)^3+b[/tex]
Where, a represents the horizontal shift and b represents the vertical shift.
If a>0, then the graph shifts left side by a units and if a<0, then the graph shifts right side by a units.
If b>0, then the graph shifts upward by b units and if b<0, then the graph shifts downward by b units.
Since the graph shifts vertically 5 units down and horizontally 4 units left, therefore the value of a is 4 and value of b is -5. The required equation is
[tex]y=(x+4)^3-5[/tex]
Therefore option 4 is correct.
Find all points on the x-axis that are 14 units from the point (3,-7).
Answer:
(3±√147, 0) ≈ (-9.124, 0) and (15.124, 0)
Step-by-step explanation:
The points (x, 0) satisfy the distance formula:
d = 14 = √((x -3)² +(0+7)²)
196 = (x -3)² +49 . . . . . square both sides
147 = (x -3)² . . . . . . . . . subtract 49
3 ±√147 = x . . . . . . . . . take the square root and add 3
The points at distance 14 from (3, -7) on the x-axis are (3±√147, 0).

Olivia divided a fraction by 3/4. The quotient was a whole number. Was the the dividend less than 3/4? Explain
Let's assume
Let's assume that fraction as 'x'
and whole number as 'n'
Olivia divided a fraction by 3/4
so, we get
[tex]\frac{x}{\frac{3}{4} }[/tex]
The quotient was a whole number
so, we get
[tex]\frac{x}{\frac{3}{4} }=n[/tex]
now, we can solve for x
[tex]\frac{3}{4}\times \frac{x}{\frac{3}{4} }=\frac{3}{4}\times n[/tex]
[tex]x=\frac{3n}{4}[/tex]
where n is whole numbers
At n=0:
[tex]x=\frac{3*0}{4}[/tex]
[tex]x=0[/tex]
here , x is not fraction
so, n=0 is not possible
At n=1:
[tex]x=\frac{3*1}{4}[/tex]
[tex]x=\frac{3}{4}[/tex]
At n=2:
[tex]x=\frac{3*2}{4}[/tex]
[tex]x=\frac{3}{2}[/tex]
we know that x is dividend
and x can be equal to 3/4
and greater than 3/4
But it can not be less than 3/4..............Answer

a card is chosen from a standard deck of cards. what is the probability that the card is a queen, given that the card is a club?
Answer:
Probability that card is queen given that card is club is [tex]\frac{4}{13}[/tex]
Step-by-step explanation:
Given : A card is chosen from a standard deck of cards.
To find : What is the probability that the card is a queen, given that the card is a club?
Solution : It is the conditional probability
[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}[/tex]
Let A is probability that card is queen.
Let B is the probability that card is a club.
Probability that card is queen given card is club [tex]P(A\cap B)=\frac{4}{52}=\frac{1}{13}[/tex]
Probability that card is club from deck of 52 cards [tex]P(B)=\frac{13}{52}=\frac{1}{4}[/tex]
To find probability that card is queen given that card is club [tex]P(A|B)[/tex]
[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}[/tex]
[tex]P(A|B)=\frac{\frac{1}{13}}{\frac{1}{4}}[/tex]
[tex]P(A|B)=\frac{1\times4}{13\times 1}=\frac{4}{13}[/tex]
Therefore, Option A is correct.
Probability that card is queen given that card is club is [tex]\frac{4}{13}[/tex]
Answer:
the correct answer was 1/13

i took my test and put 4/13 which was wrong and said that 1/13 is the right answer
A dolphin is swimming with her friend. The dolphin jumps to a height of 4.54.54, point, 5 meters above the surface of the water as her friend swims 9.89.89, point, 8 meters directly below her. What is the position of the dolphin's friend relative to the surface of the water?
The dolphin's friend is 8.63 meters below the surface of the water relative to the dolphin's jumping point.
Explanation:To solve this problem, we can use the kinematic equation that relates initial velocity, final velocity, acceleration, and displacement:
vf² = vi² + 2ad
Knowns:Plug in the knowns: (-13.0 m/s)² = (0 m/s)² + 2(-9.8 m/s²)(d)Simplify and solve for d: d = (169 m²/s²) / (-19.6 m/s²)Calculating: d = -8.63 mThe positive value of d indicates that the dolphin's friend is 8.63 meters below the surface of the water relative to the dolphin's jumping point.
The dolphin's friend is 5.3 meters below the surface of the water.
Let's reassess the problem with the given constraints more carefully.
We need to find the position of the dolphin's friend relative to the surface of the water.
1. Dolphin's height above the water:
[tex]\[ 4.5 \text{ meters above the surface} \][/tex]
2. Distance between the dolphin and her friend:
[tex]\[ 9.8 \text{ meters below the dolphin} \][/tex]
Since the friend is swimming below the dolphin, we need to subtract this distance from the height of the dolphin above the surface to find the position of the friend relative to the water surface.
3. Calculate the position of the dolphin's friend:
[tex]\[ \text{Position of friend} = 4.5 \text{ meters} - 9.8 \text{ meters} \][/tex]
[tex]\[ \text{Position of friend} = -5.3 \text{ meters} \][/tex]
This means the dolphin's friend is 5.3 meters below the surface of the water.

The triangle shown below must be congruent
True or false
That would be FALSE
They have the same angles, so they're similar triangles. For them to be congruent, the corresponding sides must have equal length. Here we have two sides of length 7, but they're not corresponding sides. If on the second triangle the 7 was the length of the side between the 60 and 62 degree vertices then we'd have equal corresponding sides and congruent triangles.
Answer: no
Step-by-step explanation: this answer would be FALSEEE
Use the graph of the parent function f(x)=√x, to describe the transformation for the graph of g(x)=√x-5
Answer : C
[tex]f(x)= \sqrt{x}[/tex]
[tex]g(x)= \sqrt{x-5}[/tex]
Parent function is f(x). In g(x) 5 is subtracted from x
If any number is added or subtracted from x, then we move left or right
When a number 'a' is added with x then we shift 'a' units to the left
When a number 'a' is subtracted from x then we shift 'a' units to the right
f(x) is our parent function. Here 5 is subtracted from x to get g(x)
For -5, the graph of g(x) is the graph of f(x) shifted right 5 units
the first answer would be C

The graph of g(x) is obtained by reflecting the graph of f(x)=4|x| over the x-axis.
Which equation describes g(x)?
A) g(x)=|x−4|
B) g(x)=|x+4|
C) g(x)=−4|x|
D) g(x)=|x|−4
That would be choice C.
The graph of 4|x| is shaped like a V whose vertex is at the origin.
Every y value will be positive for y = 4|x| as |x| is always positive and a reflection in the x axis will make every y value negative.
Through moving up c units, the graphs of g can be determined from the graph of f. If we subtract c from f(x), the graph shifts downward. Let [tex]\bold{ h(x) = f(x) - c}[/tex]. Shifting downward c units yields this graph of h from the graph of f.
Given:
[tex]\bold{f(x)=4|x|}[/tex]
Calculation:
It is stated that its graph of [tex]g(x)[/tex] is obtained by reflecting a graph of [tex]f(x)=4|x|[/tex] over the x-axis.When a figure is reflected across the x-axis, the rule for reflection is [tex]\bold{(x,y) \to (x,-y)}[/tex].To use the preceding logic, if the given function is reflected from across the x-axis, then [tex]g(x)=-f (x)[/tex].[tex]\bold{g(x)=-(4|x|)}\\\\\bold{g(x)=-4|x|}\\\\[/tex]
So, the equation [tex]g(x)=-4|x|[/tex] describes [tex]g(x)[/tex].
Therefore, the final choice is "Option C".

A rectangular prism has dimensions of x + 1, x - 1, and x. Write an expression for the total volume of the prism.
We have been given the dimensions of the rectangular prism.
Lets say that the length, width, and height of the rectangular prism are:
Length [tex]= x+1[/tex]
Width [tex]=x-1[/tex]
Height[tex]=x[/tex]
Volume of a rectangular prism is given by:
[tex]length \times width\times height[/tex]
Plugging the values of length, width, and height, we get:
Total volume of the prism [tex]= (x+1)\times(x-1)\times x[/tex]
[tex]=(x^2-1)x=x^3-x[/tex] (we have used [tex](a+b)\times (a-b)=a^2-b^2[/tex])
So, the expression for the total volume of the prism is:

You work 1.15 hours on your English Homework and 1.75 hours in your math homework. Your science homework takes 1.05 hours less than your math homework. How many more hours do you work on your homework? The answer is 4 but it's saying it's wrong
Answer:
Total time taken for doing home work = 3.6 hours.
Explanation:
Time taken for English home work = 1.15 hours.
Time taken for Mathematics home work = 1.75 hours.
Time taken for Science home work = Time taken for Mathematics home work - 1.05 hours = 1.75 - 1.05 = 0.7 hours
Total time taken for doing home work = 1.15 + 1.75 + 0.7 = 3.6 hours.
So the answer is not 4 hours, it is 3.6 hours, that is why it is showing it as wrong.
Kendall is buying a home for 119,000 she is making a 12% down payment and financing the rest with 20-year loan at 4.5% interest what is her monthly mortgage payment ?
662.46 is your answer
The required Kendall's monthly mortgage payment is $662.14.
What is interest?Simple interest is defined as the percentage of earnings on the lending for a period of time.
Here,
Kendall's down payment is 12% of $119,000, which is:
0.12 * $119,000 = $14,280
So the amount she is financing is:
$119,000 - $14,280 = $104,720
To calculate her monthly mortgage payment, we can use the formula for a fixed-payment loan:
[tex]M = P * (r / (1 - (1 + r)^{-n}))[/tex]
First, we need to calculate the monthly interest rate. The annual interest rate is 4.5%, so the monthly interest rate is:
4.5% / 12 = 0.375%
Next, we need to calculate the total number of monthly payments. Kendall has a 20-year loan, which is:
20 years * 12 months/year = 240 months
Now we can plug in the values and solve for M:
[tex]M = $104,720 * (0.00375 / (1 - (1 + 0.00375)^{-240}))[/tex]
M = $662.14
So Kendall's monthly mortgage payment is $662.14.
