What is the surface area of the cylinder?
•9377 ft2
•5787 ft2
•1,156 ft2
•2891 ft2
Answer:
3631.681108 ft^2
Step-by-step explanation:
The surface area of a cylinder is
SA = 2pi r^2 + 2pi r h where r is the radius and h is the height
= 2pi (17)^2 + 2 pi (17)(17)
= 578pi +578pi
= 1156pi
Approximate pi with the pi button

Please help me solve this short problem guys
Answer:
Step-by-step explanation:
Given equation of the quadratic function is,
y = x² + 5x - 7
Convert this equation into vertex form,
y = x² + 2(2.5x) - 7
= x² + 2(2.5x) + (2.5)² - (2.5)² - 7
= (x + 2.5)²- 6.25 - 7
= (x + 2.5)² - 13.25
Therefore, vertex of the function is → (-2.5, -13.25)
For the solutions,
y = 0
(x + 2.5)² - 13.25 = 0
x = (±√13.25) - 2.5
x = (±3.64) - 2.5
x = 1.14, -6.14
Solutions → (-6.14, 0) and (1.14, 0)
Please help me solve this I’ve been trying all day it’s impossible for me
Answer:
36; 18; -35; 0
Step-by-step explanation:
They break even again when their profit is zero, i.e. at the x-intercept (36).
The worst case scenario is when their profit is the lowest, i.e. at the minimum vertex where they produce 18 items for a profit (in this case loss) of -35 dollars.
The first root tells us that the profit will be zero when zero products are produced.

I think 60 more people
Step-by-step explanation:
You just plug in p for period 4 and period 2 then solve for N. Then it's asking for how many more in pd 4 then 2 which is 60, I think..
The difference between interior angle in centesimal measurement and sexagesimal measurement is 15° of a regular polygon. Find the number of sides of the polygon.
Answer:
8
Step-by-step explanation:
x = centesimal angle (100 degrees in a right angle)
y = sexagesimal angle (90 degrees in a right angle)
x - y = 15
x×90/100 = y
x×9/10 = y
x - x×9/10 = 15
10x/10 - 9x/10 = 15
x/10 = 15
x = 150
y = 150×9/10 = 15×9 = 135
using centesimal system :
the sum of all external angles in a polygon is 400 degrees (a full circle).
one external angle is the complement of one internal angle to 200 degrees = 200-150=50 degrees.
to find the number of sides of the polygon we need to find the number of angles or corners. and that is how many external angles fit into the full circle.
n = 400/50 = 8
the polygon has 8 sides
Solve the equation by finding square roots. x2-1/4=0
Answer:
x = ±1/2
Step-by-step explanation:
x^2-1/4=0
Add 1/4 to each side
x^2 -1/4+1/4 = 0+1/4
x^2 = 1/4
Take the square root of each side
sqrt(x^2) = sqrt(1/4)
x = ±1/2

Answer:
Value of tan( π/3 ):
[tex]{ \tt{ \frac{\pi}{3} = \frac{180}{3} = 60 \degree }}[/tex]
60° lies within the first quadrant.
[tex]{ \sf{ \tan( \frac{ \pi}{3} ) = ( \frac{1}{2} , \: \frac{ \sqrt{3} }{2}) }}[/tex]
Since it's a half:
[tex]{ \boxed{ \sf{ \tan( \frac{\pi}{3} ) = \sqrt{3} }}}[/tex]
Length of hypotenuse:
[tex]{ \bf{ \sin(31 \degree) = \frac{16.5}{h} }} \\ { \sf{h = 32.04}}[/tex]
Hypotenuse = 32.0
Suppose f(x) = x^2. what is the graph of g(x)
Answer: g(x) = (1/16)*x^2
========================================================
Explanation:
Plug x = 4 into f(x) to find that f(4) = 16.
The output y = 16 drops to y = 1. We've multiplied by 1/16 to get this to happen.
In other words,
g(x) = (1/16)*f(x)
g(4) = (1/16)*f(4)
g(4) = (1/16)*16
g(4) = 1
So we can say that,
g(x) = (1/16)*f(x)
g(x) = (1/16)*x^2
and furthermore, we can say f(x) has been vertically compressed by a factor of 16.
3. In a primary election, 35% of voters voted for Goron, 15% voted for Smith, 40% voted for Fishman, and 10% voted for other candidates. (a) It was estimated that 280 people were going to vote. If this was true, how many people would have voted for Goron? Show your work. (b) Forty people voted for "Other." Was the estimate of total voters from Part (a) accurate? Explain.
Answer:
98 ppl voted for Gordan
Step-by-step explanation:
a) 35% of 280=98
b) 15% of 280=42
40% of 280=112
10% of 280=28
Add 98, 42, 112, and 28 and you get 280! Hope this helps :)
Working together, Nadia and Olivia can clean a horse stable in 8 hours. Had Nadia cleaned it alone, it would have taken her 12 hours Find out how long it would take Olivia to clean the horse stable by herself.
Answer:
24 hours
Step-by-step explanation:
The formula is
1/a + 1/b = 1/c where a and b are the times alone and c is the times together
1/12 + 1/b = 1/8
Multiply by 24b to clear the fractions
24b(1/12 + 1/b = 1/8)
2b + 24 = 3b
Subtract 2b from each side
2b +24-2b = 3b-2b
24 = b
The zeros of a quadratic function are 6 and -4. Which of these choices could be the function?
A.
f(x) = (x + 6)(x + 4)
B.
f(x) = (x + 6)(x − 4)
C.
f(x) = (x − 6)(x + 4)
D.
f(x) = (x − 6)(x − 4)
Answer:
C
Step-by-step explanation:
If x = a is a zero of f(x) then (x - a) is a factor of f(x)
Here the zeros are x = 6 and x = - 4 then the corresponding factors are
(x - 6) and (x - (- 4) ) , that is (x - 6) and (x + 4)
Then f(x) is the product of the factors
f(x) = a(x - 6)(x + 4) ( a is a multiplier )
If a = 1 , then
f(x) = (x - 6)(x + 4) ← is a possible choice → C
Answer:
С.
Step-by-step explanation:
f(x) = (x − 6)(x + 4)
x-6=0
x1=6
x+4=0
x2=-4

Please help, easy geometry work
Step-by-step explanation:
Find the slope of AB
: The slope is
[tex] \frac{7 - 0}{3 - 8} = - \frac{7}{5} [/tex]
Find the y intercept by plugging coordinates in
[tex]0 = - \frac{ 7}{5} (8) + b[/tex]
[tex]0 = \frac{ - 56}{5} + b[/tex]
[tex]b = \frac{56}{5} [/tex]
Find CD: We know that AB and CD are parallel to each other so this means they both have the same slope.
We can find the next point by subtracting 7 from the y coordinate of Point D, Adding 5 to the x coordinate of Point D.
Point C=(10,-2).
Find the y intercept by a plugging coordinates in
[tex] 5 = - \frac{7}{5} (5) + b[/tex]
[tex]5 = - 7 + b[/tex]
[tex]12 = b[/tex]
So the Equation of Line CD is
[tex] - \frac{7}{5} x + 12[/tex]
Two numbers have a sum of 35 and an
LCM of 42. What are the two numbers?
HELP PLEASE <3
Answer:
14, 21
Step-by-step explanation:
LCM : least common multiplier.
x + y = 35
LCM = 42
means that there is a combination of 2 of the following divisors of 42 :
2, 3, 6, 7, 14, 21
so, which two of these numbers can create the sum of 35 ?
only 14 and 21

Hey there! For this you will need to use the rule of subtracting fractions. 4 (the denominator) x 2 (to make it them equal) is 8. 3 x 2 is 6. The new fraction is 1 and 6/8. Now, subtract these to get your final answer, 1 and 1/8.
Hope this helps!
