How to find maximum and minimum values of a parabola
Answer:
Step-by-step explanation:
Finding max/min: There are two ways to find the absolute maximum/minimum value for f(x) = ax2 + bx + c: Put the quadratic in standard form f(x) = a(x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens up, and it is a minimum functional value of f.

What is the completely factored form of f(x)=x^3+5x^2+16x+80 ?
f(x)=(x−5)(x−4i)(x+4i)
f(x)=(x+5)(x−4i)(x+4i)
f(x)=(x−5)(x−4)(x+4)
f(x)=(x+5)(x−4)(x+4)
Answer:
B) [tex]f(x)=(x+5)(x-4i)(x+4i)[/tex]
Step-by-step explanation:
[tex]f(x)=x^3+5x^2+16x+80\\\\f(x)=x^2(x+5)+16(x+5)\\\\f(x)=(x^2+16)(x+5)\\\\f(x)=(x-4i)(x+4i)(x+5)[/tex]

The diameter of a circle is 42 ft. Find its area to the nearest whole number.
Answer:
5539 or 1764[tex]\pi[/tex]
Step-by-step explanation:
to find the area, we need the radius
The radius(R) is half of the diameter(D)
R = D/2
R = 42/2
R = 21
area of a circle(A) = pi x radius[tex]^{2}[/tex]
A = pi( which most times in a problem, equals 3.14) x 42[tex]^{2}[/tex]
A = 3.14 x 1764
A = 5538.96
A(when rounded) = 5539
Please help me with question 36. I don’t know the answer
Answer:
Period = [tex]\frac{\pi }{4}[/tex]
Amplitude = 4
Step-by-step explanation:
To find the answer, use the form acos(bx - c) + d:
a = -4
b = 8
c = 0
d = 0
The amplitude is the absolute value of a, so:
|a| = |-4| = 4
To find the period, use this equation:
[tex]\frac{2\pi }{b}[/tex]
Replace b with 8 in the formula and solve:
[tex]\frac{2\pi }{8} = \frac{\pi }{4}[/tex] Simplify
So, the period is equal to [tex]\frac{\pi }{4}[/tex]

Jimmy has a new job and plans to start saving some money. he decides to use his knowledge of geometric series to set up a savings plan that will start off with him setting aside a small amount each week, and end with him saving a large amount. in each of the first 5 weeks of his job, he wants to raise $2 to the number of weeks he has been working, multiply it by 3, and add that amount to the savings account. use summation notation to write this as a sum and find the total amount jimmy will save in 5 weeks.
The equation that represents the amount saved is T(n) = 3 * (2^n), and the total amount saved in 5 weeks is $186
How to determine the sum of total amount?The statement is given as:
raise $2 to the number of weeks he has been working, multiply it by 3,
Let the number of weeks be n.
So, we have:
T(n) = 3 * (2^n)
For week 1 to 5, we have:
T(1) = 3 * (2^1) = 6
T(2) = 3 * (2^2) = 12
T(3) = 3 * (2^3) = 24
T(4) = 3 * (2^4) = 48
T(4) = 3 * (2^5) = 96
The sum is then calculated as:
Sum = 6 + 12 + 24 + 48 + 96
Evaluate the sum
Sum = 186
Hence, the total amount saved in 5 weeks is $186

The domain is all real numbers, and the range is all real numbers less than or equal to 4.
How to determine the true statement?The equation of the function is given as:
f(x) = -(x + 3)(x -1)
The above function is a quadratic function, and the domain of a quadratic function is the set of all real numbers
Expand the function
f(x) = -(x² + 3x - x - 3)
f(x) = -(x² + 2x - 3)
Expand
f(x) = -x² - 2x + 3
Differentiate
f'(x) = -2x - 2
Set to 0
-2x - 2 = 0
Add 2 to both sides
-2x = 2
Divide through by -2
x = -1
Substitute x = -1 in f(x)
f(-1) = -(-1 + 3)(-1 -1)
Evaluate
f(-1) = 4
This means that the maximum value of the function is 4
Hence, the domain is all real numbers, and the range is all real numbers less than or equal to 4.

In Galton’s height data, the least-squares line for predicting forearm length (y) from height (x) is y = −0.2967 + 0.2738x.
Predict the forearm length of a man whose height is 72 in. Round the answer to three decimal places.
Using the line of best fit, it is found that the prediction of the forearm length of a man whose height is of 72 in is of 19.417 in.
What does the line of best fit state?It states that the predicted forearm length of a person of height x is given by:
y = -0.2967 + 0.2738x.
In this problem, the height is of x = 72 in, hence:
y = -0.2967 + 0.2738(72) = 19.417 in.

f(x) = 3x + 2
What is f(5)?
Answer:
17
Step-by-step explanation:
→ f(x) = 3x + 2
→ f(5) = 3(5) + 2
→ 15 + 2
→ 17 is the answer.
Answer:
F(5) = 17
Step-by-step explanation:
to solve, we just need to plug all values of x into 5 as shown
f(x) = 3x + 2
f(5) = (3*5) + 2
then following the format of PEMDAS (explained at footer) we solve the new equation
f(5) = (3*5) + 2
f(5) = 15 + 2
f(5) = 17
therefor F(5) is equal to 17

If you were going to buy a $60 game, which would save you more money: a coupon for 30% off or a
$20 off coupon?
Answer:
A coupon for 30%
Step-by-step explanation:
A coupon takes the a certain percentage of a price and subtracts it (a discount). A coupon for 30% off takes 30% of the price which is $60 and subtracts it, same goes for the $20 off coupon. Because a greater percentage is being taken off of the price, the 30% off coupon would save someone more money.

Shelly spent $235 to rent a moving van. The equation above shows the relationship
between the number of days she rented the van, d, and the number of miles she drove
the van, m. If she rented the van for 3 days, how many miles did she drive the van?
The number of miles she drove the van for is 250 miles
Solving linear equationsFrom the question, we are to determine the number of miles Shelly drove the van
The given equation which shows the relationship between the number of days she rented the van, d, and the number of miles she drove the van, m is
20d + 0.7m = 235
Now, if she rented the van for 3 days, that is, d = 3
Putting the value of d = 3 into the equation to determine the value of m
We get
20(3) + 0.7m = 235
60 + 0.7m = 235
0.7m = 235 - 60
0.7m = 175
m = 175 / 0.7
m = 250
Hence, the number of miles she drove the van for is 250 miles

Alice, a 16-year-old, gave birth to a baby boy last year. how will this affect the likelihood that her 13-year-old sister, marie, will have a baby
Answer:
I think that the actions of older people/family members around you greatly influence that thoughts/actions of a younger child. Since Marie looks up to Alice, Marie probably thinks that having a child at such a young age is a good idea. Therefore if Alice gave birth at the age of 15, there is a high chance her younger sister will follow in her footsteps.
