Gretchen made a paper cone to hold a gift for a friend. The paper cone was 15 inches high and had a radius of 2 inches. Find the volume of the paper cone to the nearest tenth. Use 3.14 for π.
Answer
91.67inch^3
Step-by-step explanation:
The volume of a cone can be calculated using below formula
V= 1/3 π.r^2h
Where h= height of the cone
r= radius of the cone
V= volume of the cone
Given :
height= 11 inches
radius= 5 inches
π= 3.14
Then substitute into the formula we have
V= 1/3 × 3.14× 5^2 ×11
V= 91.67inch^3
Therefore volume of the cone is 91.67inch^3

[tex]6x^2 +17x -3\\\\=6x^2 +18x-x-3\\ \\=6x(x+3)-(x+3)\\ \\=(x+3)(6x-1)\\\\\text{The length and width of the rectangle are}~ (6x-1)~ \text{and}~ (x+3)[/tex]
Answer:
[tex]\textsf{length}=6x - 1[/tex]
[tex]\textsf{width}=x+3[/tex]
Step-by-step explanation:
Area of a rectangle = length × width
Given area: [tex]A=6x^2+17x-3[/tex]
Therefore, [tex]6x^2+17x-3=\sf length \cdot width[/tex]
To find the length and width, we need to factorize the given expression for area.
To factor a quadratic in the form [tex]ax^2+bx+c[/tex]
Find 2 two numbers (d and e) that multiply to ac and sum to bRewrite b as the sum of these 2 numbers: d + e = bFactorize the first two terms and the last two terms separately, then factor out the comment term.[tex]6x^2+17x-3 \implies a=6, b=17, c=-3[/tex]
[tex]ac=6 \cdot -3=-18[/tex]
[tex]d+e=17[/tex]
So we are looking for a pair of numbers that multiply to -18 and sum to 17.
Factors of 18: 1, 2, 3, 6, 9, 18
Therefore, the two numbers (d and e) that multiply to -18 and sum to 17 are:
18 and -1
Rewrite [tex]17x[/tex] as [tex]+18x-x[/tex]:
[tex]\implies 6x^2+18x-x-3[/tex]
Factor first two terms and last two terms separately:
[tex]\implies 6x(x+3)-1(x+3)[/tex]
Factor out common term [tex](x+3)[/tex]:
[tex]\implies (6x-1)(x+3)[/tex]
As length > width,
[tex]\textsf{length}=6x - 1[/tex]
[tex]\textsf{width}=x+3[/tex]

Answer:
-a^3 -3a^2
Step-by-step explanation:
(fg) (x) = x^2 (x-3)
= x^3 - 3x^2
(fg) (-a) = (-a)^3 -3 (-a)^2
= -a^3 -3a^2

uhhh it already solved and also, its the answer because if theres like a "+-" you can just convert it to "-" so then it will be
11 - 11
11 - 11 = 0
Answer:
0
Step-by-step explanation:
as + and then - is - so 11- 11 = 0

= 2 * π * 27
= 169.646 m
why is l-8l>l2l even though -8,2
Answer:
the absolute value of (-8) is 8 and the absolute value of (2) is 2
so l-8l>l2l
Step-by-step explanation:
The circumference of a circle is 106.76 millimeters. What is the circle's diameter?
Use 3.14 for .
Answer:
CIRCUMFERENCE (of a circel) = 3.14 * DIAMETER
C = 3.14 * D
106.76 mm = 3.14 * D
hence, D = (106.76 mm)/ 3.14
D = 34mm
Therefore the diameter of the circle is 34mm

Determine whether 2x+2y= -6 is a function?
Answer:
It's a function because when you simplify it becomes y=-x-3. the only reason it wouldn't be a function would be if the equation were to be x = a random number that is not a variable. The equation would not pass the vertical line test which is the requirement to see if an equation is a function.
Simply put, it's a function.

what amount is closest to a quart 100 milliliters or 500 milliliters or one liter or 10 liters
Answer:
1 liter
Step-by-step explanation:
100 milliliters = 0.10566882 quarts
500 milliliters = 0.52834411 quarts
1 liter = 1.05668821 quarts
10 liters = 10.5668821 quarts
______________________________
From this, we can see that 1 liter is closest to a quart.

What is the area of a triangle with a base of 16m and a height of 3m?
Answer:
24 m²
Step-by-step explanation:
[tex]A = \frac{hb}{2}[/tex]
A = (16)(3)/2
A = 48/2
A = 24
The units will be m² since it is area.

Consider
[tex] log_{ \sqrt{x} }( {x}^{k} ) [/tex]
[tex] log_{ \sqrt{x} }( {( \sqrt{x} }^{2})^{k} ) [/tex]
[tex] log_{ \sqrt{x} }{( \sqrt{x})^{2k} } ) [/tex]
we know that
[tex] log( {a}^{b} ) = b log(a) [/tex]
===
[tex]2k (log_{ \sqrt{x} }( \sqrt{x} ) )[/tex]
Also we know that
[tex] log_{a}(a) = 1[/tex]
===
[tex]2k( log_{ \sqrt{x} }( \sqrt{x} ) = 2k \times 1 = 2k[/tex]
Hence
[tex] log_{ \sqrt{x} }( {x}^{k} ) = 2k[/tex]

The table gives a set of outcomes and their probabilities. Let A be the event "the outcome is
prime". Let B be the event "the outcome is a divisor of 3". Find P(A|B).
Answer:
P(A|B) = 0.5
Step-by-step explanation:
A: set of prime numbers ={1,2,3}
B: set of divisors of 3 ={1,3}
P(A)=P(1)+P(2)+P(3)= 0.1+0.1+0.3 =0.5
P(B)=P(1)+P(3)=0.1+0.3=0.4
P(A|B) means: probability of A knowing that B
In other words we have to find the probability that a prime outcome occurs knowing that it is a divisor of 3
Its formula is given by:
P(A|B) = P(AintersectionB) /P(B)
A intersection B: outcome is prime and a divisor of 3 at the same time. (common elements between sets A and B)
A int B= {1,3}
P(AintB)= P(A)xP(B) = 0.5x0.4=0.2
Now back to the formula:
P(A|B) =P(AintB) / P(B)
=0.2/0.4=0.5

for the function f, use compisition of functions to show that f^-1 is a given.
let f(x)=(1+x)/x show that f^-1(x)=1/x-1
Step-by-step explanation:
If we have f(x) and it's inverse, and we compose them
we will get
[tex]f {}^{ - 1} (f(x) = x[/tex]
So here we compose
[tex]( \frac{1}{ \frac{1 + x}{x} - 1} )[/tex]
[tex]( \frac{1}{ \frac{1}{x} + 1 - 1} [/tex]
[tex] \frac{1}{ \frac{1}{x} } [/tex]
[tex]x [/tex]
So the composition is x, so they are inverses.
