To find volume of Cylinder first we should know radius of Cylinder. We can get radius by diameter using this formula:-
[tex]\boxed{\rm Diameter = 2 radius}[/tex]
[tex]\\\\[/tex]
[tex]\hookrightarrow\sf Diameter = 2 radius[/tex]
[tex]\\[/tex]
[tex]\hookrightarrow\sf 20= 2 radius[/tex]
[tex]\\[/tex]
[tex]\hookrightarrow\sf \dfrac{20}{2}= radius[/tex]
[tex]\\[/tex]
[tex]\hookrightarrow\sf \dfrac{2\times10}{2}= radius[/tex]
[tex]\\[/tex]
[tex]\hookrightarrow \sf \dfrac{\cancel2\times10}{\cancel2}= radius[/tex]

Now Finally Let's find volume of Cylinder.
we know:-
[tex]\boxed{\rm Volume ~ of ~ Cylinder = \pi radius^2 \times height}[/tex]

So:-
[tex]\dashrightarrow\sf Volume ~of ~Cylinder = \pi radius^2\times height\\[/tex]
[tex]\\\\[/tex]
[tex]\dashrightarrow\sf Volume ~of ~Cylinder = \pi (10)^2\times 5\\[/tex]

How many points of inflection will f(x) = 3x^5 + 2x^4 – 5x 52 – 12 have?
A)3
B)2
C)5
D)4
There are two points of inflection in the graph of f(x).
Option B is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find the inflection points of a function, we need to find its second derivative and set it equal to zero.
So,
Let's start by finding the first and second derivatives of f(x).
First, we find the first derivative of f(x).
f'(x) = 15[tex]x^4[/tex] + 8x³ - 260x² - 5x²
Then,
We find the second derivative of f(x):
f''(x) = 60x³ + 24x² - 520x - 10x
Next, we set f''(x) equal to zero and solve for x.
60x³ + 24x² - 520x - 10 = 0
10 (2x² - 13x - 1) = 0
2x² - 13x - 1 = 0
Now,
Using the quadratic formula,
we find the roots of this equation:
x = (13 ± √(13² + 8))/4
x = 13 ± √177) / 4
x = (13 + √177)/4 and x = )13 - √177)/4
x = 2.22 and x = -0.23
Therefore,
There are two points of inflection in the graph of f(x).

Answer:
[tex]y=-\frac{1}{5} x+2[/tex]
Step-by-step explanation:
f(x) = [tex]\frac{5}{x}[/tex] ⇒ f(x) = [tex]5x^{-1[/tex]
Use the power rule to diferentiate:
f'(x) = [tex]-5x^{-2[/tex]
Plug in the value to differentiate at:
f'(5) = [tex]-5(5)^{-2[/tex] = [tex]-\frac{1}{5}[/tex] = [tex]m[/tex]

Find the length of the hypotenuse of a 45°-45°-90° triangle with a leg length of 77 centimeters.
The sum of the square of the hypotenuse is equal to the sum of the square of the other sides.The length of the hypotenuse of the triangle is l = √14
Pythagoras theoremThe sum of the square of the hypotenuse is equal to the sum of the square of the other sides.
Given that one of the sides is √7, hence;
l^2 = (√7)^2 + (√7)^2
l^2 = 7 + 7
l^2 = 14
l = √14
Hence the length of the hypotenuse of the triangle is l = √14

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 pounds. The truck is transporting 60 large boxes and 55 small boxes. If the truck is carrying a total of 4050 pounds in boxes, how much does each type of box weigh?
Answer:
the large boxes weigh 40 pounds and the smaller boxes weigh 30 pounds
Step-by-step explanation:
define variables:
b is the weight of large boxes and s is the weight of small boxes. you can create two equations to represent what you know:
b + s = 70 (the weight of one large box and one small box is 70 pounds)
60b+ 55s = 4050 (the total weight of the 60 large boxes and the 55 small boxes is 4050)
then by making one of the equations equal to a variable, you can use substitution to solve.
s = 70 - b
so 60b + 55s = 4050 now becomes:
60b + 55(70 - b) = 4050, and next you solve for b
60b + 3850 - 55b = 4050
5b = 200
b = 40.
now you know that the large boxes weigh 40 pounds. to solve for the small box weight, you plug in b in either equation. i am going to choose the first once since it's fewer steps
b + s = 70 -> 40 + s = 70
s = 30
and now you know that the smaller boxes weigh 30 pounds.

x should be 8 + 17 and then multiply the 110 degrees by 8 + 17
Answer:
x = 6
The marked angle is 110°
Step-by-step explanation:
See how there are 8 angles in this type of image. The angles either are EQUAL, or they ADD UP TO 180°. It's just two numbers for the degrees of these angles. Four of them are the same and the other four are the same.
In your question the 8 + 17x = 110°
Solve.
Subtract 8.
17x = 102
Divide by 17.
x = 6
If your question says find the measure of the angle it is 110°, if you are to find x, then x = 6.
Jfyi, four of these angles are 110°. The other four are 70°.

When a fraction equals zero :
5.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
20y+4x-15
————————— • 20 = 0 • 20
20
Now, on the left hand side, the 20 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
20y+4x-15 = 0
Equation of a Straight Line
5.2 Solve 20y+4x-15 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 20y+4x-15 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 3/4 so this line "cuts" the y axis at y= 0.75000
y-intercept = 15/20 = 3/4 = 0.75000
Calculate the X-Intercept :
When y = 0 the value of x is 15/4 Our line therefore "cuts" the x axis at x= 3.75000
x-intercept = 15/4 = 3.75000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 0.750 and for x=2.000, the value of y is 0.350. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.350 - 0.750 = -0.400 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -0.400/2.000 = -0.200
Geometric figure: Straight Line
Slope = -0.400/2.000 = -0.200
x-intercept = 15/4 = 3.75000
y-intercept = 15/20 = 3/4 = 0.75000
