find f(2) given f(x) = 2x^2 + 5x - 21
Answer:
f(2) = -3
Step-by-step explanation:
Find f(2) given f(x) = 2x^2 + 5x - 21
Since on the left side, x is replaced by 2, on the right side, x should also be replaced by 2.
f2 = 2(2)² + 5(2) - 21
2 x 2² = 2 x 4 = 8
5 x 2 = 10
8 + 10 = 18
18 - 21 = ?
-(21 - 18 = 3)
-21 + 18 = -3
f(2) = -3

Find the area of the circle to the nearest tenth. Use 3.14 for π.
Answer:
Step-by-step explanation:
Use the formula for area of a circle
A = [tex]\pi r^{2}[/tex]
The diameter is 8ft, if there was only a line from the middle to the edge of the circle, then it would be radius
The radius is half the diameter so divide 8 by two and you get the radius
Plug in the radius into the formula
A = [tex](4ft)^{2} \pi[/tex]
the parenthesis indicate you aren't only squaring the ft, but also the 4
4ft * 4ft = 16[tex]ft^{2}[/tex]
(remember you are also multiplying the unit, in this case feet)
A = [tex]16ft^{2} \pi[/tex]
there aren't parenthesis here, meaning you aren't squaring the 16
A = 50.24[tex]ft^{2}[/tex]

The volume of cup A is 1570.8 cm³ while the volume of cup B is 6283 cm³
Volume
Volume is the amount of space occupied by a three dimensional object or figure.
The cup has the shape of a cylinder, the volume is:
Volume = π * radius² * height
For cup A:
Volume = π * (10/2)² * 20 = 1570.8 cm³
Let each punch be 1 cm³, the number of cups needed = 1570.8 cm³ / 1 cm³ = 1571
For cup B:
Volume = π * (20/2)² * 20 = 6283 cm³
Let each punch be 1 cm³, the number of cups needed = 6283 cm³ / 1 cm³ = 6283
The volume of cup A is 1570.8 cm³ while the volume of cup B is 6283 cm³

Find the percentage error |sinθ - θ|/sin(θ)*100 this approximation introduces for an angle of 0. 020 radians.
Considering the given angle and the given formula, it is found that the percentage error for an angle of 0.02 radians is of 0.0067%.
What is the percentage angle for an angle?For an angle [tex]\theta[/tex], it is given by the following formula:
[tex]P = 100\frac{|\sin{\theta} - \theta|}{\sin{\theta}}[/tex]
In this problem, the angle is of [tex]\theta = 0.02[/tex], hence:

John can eat a melon 2 minutes faster than Sam can eat an identical melon. If they share one melon, they can eat it together in 2.4 minutes. How long does it take each of them to eat a melon?
Answer:
4 mins
Step-by-step explanation:
I guess not to sure ask teacher
Sam eats the melon in 0.2 minutes.
John eats the melon in 2.2 minutes.
What are the linear equations that represent this question?
x - y = 2 equation 1
x + y = 2.4 equation 2
Where:
x = minutes John eats the melon
y = minutes Sam eats the melon
How many minutes does John eat the melon?Add equation 1 and equation 2 together
2x = 4.4
Divide both sides by 2
x = 2.2
How many minutes does Sam eat the melon?
Substitute for x in equation 1
2.2 - y = 2
y = 2.2 2
y = 0.2 minutes

Error Analysis A gardener plans to extend the length of a rectangular garden by 7 feet. Letx represent the garden's original length. The expression 9(x + 7) represents the area of the garden, where 9 is the width, in feet, and (x + 7) represents the extended length, in feet, of the garden When asked for the area of the extended portion, the gardener incorrectly said it was 16 square feet. Expand the expression to find the area of the extension.
Answer:
9(x+7)
Distribute the 9 by multiplying it to x and 7
9x+63
The area of the extension is 63.
The gardener added 9 and 7 instead of multiplying.

Answer:
-21
Step-by-step explanation:
Each of those lines is -3
If you look at the -10, it goes down 2 lines and goes to -16 meaning that if it only went down one line it would only go to -13
Showing that each line is worth -3
It goes down 2 lines from -16 (-6)
so if you go down 6 from -16 that would get you to -21
The answer is: -18
That is because, on the number line, they already have 2 numbers. They are -10 to -16. To go from -10 to -16, you subtract 2. Since the mark is the same distance away as -10 to -16 on this number line, you would subtract 2 from -16, which would be -18.

(PLS HELP)The diameter of a cylindrical water tank is 12 ft, and its height is 17 ft. What is the volume of the tank?
Use the value 3.14 for л, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Solution:
We know that:
Volume of a cylinder = πr²h.Finding the radius of the cylindrical water tank:
[tex]\rightarrow Diameter = 2(Radius)[/tex]
[tex]\rightarrow Radius = \frac{Diameter}{2} = \frac{12}{2} = 6 \ feet[/tex]
Now, let's find the volume of the cylinder by substituting the radius.
Finding the volume of the cylinder:
[tex]\rightarrow \tex V \tex o \tex l \tex u \tex m \tex e\tex \ \tex of \tex \ c \tex y \tex l \tex i \tex n \tex d \tex e \tex r = \pi r^{2} h[/tex]
[tex]\rightarrow \tex V \tex o \tex l \tex u \tex m \tex e\tex \ \tex of \tex \ c \tex y \tex l \tex i \tex n \tex d \tex e \tex r = (3.14)( 6^{2})( 17)[/tex]
[tex]\rightarrow \tex V \tex o \tex l \tex u \tex m \tex e\tex \ \tex of \tex \ c \tex y \tex l \tex i \tex n \tex d \tex e \tex r = (3.14)( 36)( 17)[/tex]
[tex]\rightarrow \tex V \tex o \tex l \tex u \tex m \tex e\tex \ \tex of \tex \ c \tex y \tex l \tex i \tex n \tex d \tex e \tex r = 1921.68 \ feet^{3}[/tex]
Rounding to the nearest whole number:
[tex]\rightarrow \tex V \tex o \tex l \tex u \tex m \tex e\tex \ \tex of \tex \ c \tex y \tex l \tex i \tex n \tex d \tex e \tex r = 1921.68 \ feet^{3}[/tex]
[tex]\rightarrow \tex V \tex o \tex l \tex u \tex m \tex e\tex \ \tex of \tex \ c \tex y \tex l \tex i \tex n \tex d \tex e \tex r = 1922 \ feet^{3} \ (Rounded \ to \ nearest \ whole \ number)[/tex]
Thus, the volume of the cylinder is 1922 feet³ (Rounded).
[tex]\\ \rm\rightarrowtail V=\pi r^2h[/tex]
[tex]\\ \rm\rightarrowtail V=\pi (6)^2(17)[/tex]
[tex]\\ \rm\rightarrowtail V=36(17)\pi [/tex]
[tex]\\ \rm\rightarrowtail V=612\pi[/tex]
