HELP PLS!! What is the diameter of a circle whose circumference is 16pi centimeters?
32 cm
16 cm
4 cm
8 cm
Answers
answer: 8
Explanation:
Use the formula for the area of a circle:
A = π r 2
Here, the area is 16 π
16 π = π r 2
Divide both sides by
16 = r 2
Take the square root of both sides:
√ 16 = √ r 2
4 = r
Since the radius of the circle is
4
, the diameter is twice that:
d = 4 × 2 = 8

What is the quotient of 2^x3+ 3^x2 + 5x-4 divided by x^2 + x +1?
Answers
Answer:
quotient: 2x+1 Remainder: 2x-5
Step-by-step explanation:
2 x³ + 3 x² + 5 x - 4 = (2 x + 1) × (x² + x + 1) + 2 x - 5
The quotient of 2x³ + 3x² + 5x - 4 divided by x² + x + 1 will be 2x + 1 and [(2x - 5) / (x² + x + 1)]. Then the correct option is D.
What is a polynomial?A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.
The quotient of 2x³ + 3x² + 5x - 4 divided by x² + x + 1. Then we have
x² + x + 1 )2x³ + 3x² + 5x - 4 (2x + 1
- 2x³ - 2x² - 2x
x² + 3x - 4
- x² - x - 1
2x - 5
The quotient of 2x³ + 3x² + 5x - 4 divided by x² + x + 1 will be 2x + 1 and [(2x - 5) / (x² + x + 1)]. Then the correct option is D.

There is a line that includes the point (3, 3) and has a slope of 4. What is its equation in
slope-intercept form?
Answers
Answer:
y = 4x - 9Step-by-step explanation:
The equation in point-slope form with slpope of m and including point (x₁,y₁) is:
y - y₁ = m(x - x₁)
m = 4
(3, 3) ⇒ x₁ = 3, y₁ = 3
So:
y - 3 = 4(x - 3) ← the point-slope form
y - 3 = 4x - 12 {add 3 to both sides}
y = 4x - 9 ← the slope-intercept form
Given f(x)=3(x-1)(x-7) what is the minimum output value of the function
Answers
Answer:
-27
Step-by-step explanation:
f(x) = 3(x-1)(x-7)
= (3x-3)(x-7)
= 3x^2 - 24x + 21
when f(x) = 0, x = 7 or 1
x-intercept of vertix of the graph = (7+1 )/ 2 = 4
f(x) attains it's minimum when x = 4
The minimum output value = 3(4-1)(4-7) = -27
1. Michael and 6 friends went to the movies. There, they each bought movie tickets and a bag of popcorn to share among them all. Michael used the expression 7t + 4.50 to find the total cost. a) What is the variable and what does it represent in the expression? Explain.
Answers
Answer:
The variable is t
t represent the cost of movie tickets
Step-by-step explanation:
Given:
Total cost = 7t + 4.50
The variable is t
Michael + 6 friends = 7 people
4.50 represent the cost of popcorn
t represent the cost of movie tickets
For instance,
If the cost of a movie tickets is $2
Then,
t = 2
Total cost = 7t + 4.50
= 7(2) + 4.50
= 14 + 4.50
= 18.50
Total cost = $18.50

Find the total package price from each store and then calculate how much you"lol save if you purchase the less expensive package
Answers
Complete Question:
You're planning to buy a new computer, monitor, and printer for your office. You've received the following prices from two stores:
Store 1 Store 2
Computer: 2,500 Computer: 2,350
Monitor: 595 Monitor: 435
Printer: 398 Printer: 349
Find the total package price from each store and then calculate how much you'll save if you purchase the less expensive package.
Answer:
[tex]Total = 3493[/tex] --- Store 1
[tex]Total = 3134[/tex] --- Store 2
[tex]Saved = 359[/tex]
Step-by-step explanation:
From store 1, the total cost is:
[tex]Total = 2500 + 595 + 398[/tex]
[tex]Total = 3493[/tex]
For store 2, the total cost is
[tex]Total = 2350 + 435 + 349[/tex]
[tex]Total = 3134[/tex]
By comparison: It is cheaper to buy from store 2
Because [tex]3134 < 3493[/tex]
Amount saved is calculated by subtracting the cheaper cost from the expensive cost:
i.e.
[tex]Saved = 3493 - 3134[/tex]
[tex]Saved = 359[/tex]

A customer pay 72$ for 18 sandwiches. If each sandwich cost the same amount , what is the cost per sandwich, in dollars?
Answers
Answer:
Each sandwich costs 4$.
Step-by-step explanation:
To find the answer we will divide 72$ by 18 and we get 4$.
The number of sandwiches and the total price of sandwiches are directly proportional.
Cost of 18 sandwiches = $72
Cost of 1 sandwich = $72/18
= $4
Hence the cost of 1 sandwich is $4.

A Circular pool has diameter of 24 feet what's the area of the cover - 452.16 square feet - 75.36 square feet - 150.72 square feet - 1,808.64 square feet
Answers
Answer: 452.16 square feet
Step-by-step explanation:
The formula that is used to calculate the area of a circle is given as:
= πr²
where π = 3.14
r = Diameter/2 = 24/2 = 12
Area = πr²
= 3.14 × 12²
= 3.14 × 144
= 452.16 feet²
Therefore, the answer is 452.16 square feet.

1921.68mm^3
Step-by-step explanation:
Given data
H=17 millimeters
R=6 millimeters.
We know that the expression for the volume of cylinder is
V= πr^2h
substitute
V= 3.14*6^2*17
V= 3.14*36*17
