Answers
Answer: 909.03
Step-by-step explanation:
We know that the equation is an exponential function, it can be written as y=ab^x
\(100 &=a b^{6.5} \dots \mathrm{Equation \ 1} \\11 &= a b^{1} \\\)
\(\Rightarrow ab^1=11\)
\(\Rightarrow \frac{ab^1}{b}=\frac{11}{b};\quad \:b\ne \:0\)
\(\Rightarrow a=\frac{11}{b}\)
a = 11/b, substitute it in equation 1
\(100 &=a b^{6.5}\)
\(\Rightarrow 100=\left(\frac{11}{b}\right)b^{6.5}\)
\(\Rightarrow 100b=11b^\frac{11}{2}\)
\(\Rightarrow 11\sqrt{b^{11} } =100b\)
\(\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}\)
\(\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}\)
\(\Rightarrow {b^{11} } =\frac{10000}{121}}\)
\(\Rightarrow {b} =\frac{\sqrt[11]{10000 \cdot 11^9} }{11}\)
\(\Rightarrow {b} = 1.49379\)
a = 11/b
a = 11/(1.49379)
a = 7.36382
Equation: y = (7.36382)(1.49379)^x
Now plug in 12 for x:
\(\Rightarrow { \left(7.36382\right)\left(1.49379\right)^{12}\)
\(\Rightarrow 7.36382\cdot \:1.49379^{12}\)
\(\Rightarrow 7.36382\cdot \:123.44530\dots\)
\(\Rightarrow 909.03\)
Therefore, f(12) = 909.03 for the exponential function

The mean increases by 1.7°.
The mean decreases by 1.7°.
The mean increases by 8.6°.
The mean decreases by 8.6°.
Answers
Answer:
The mean increases by 1.7°
Step-by-step explanation:
1) Find the mean of the numbers given first
Mean = sum of number ÷ number of numbers
Sum of numbers = 58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 = 965
Number of numbers = 12
965 ÷ 12 = 80.41666....2) Find the mean of numbers including the additional 103
Sum of numbers = 58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 103 = 1068
Number of numbers = 13
1068 ÷ 13 = 82.15384623) Find the difference
If we use the results rounded to one decimal place we will be left with 80.4 and 82.2
82.1538462 - 80.41666... = 1.7The answer closest to the options given would be 'The mean increases by 1.7'Hope this helps, have a lovely day :)

Jacquie has 20 postcards in her collection. each time she goes on vacation she buys 8 postcards to add to her collection. The total number of postcards y can be represented by the equation y=8x+20. Complete the following statements regarding the line.
The slope of the line is ___ and the y-intercept is ___. The ___ represents the number of postcards when she began collecting and the ___ represents the number of postcards added each vacation.
Answers
Answer:
The slope of the line is 8 and the y-intercept is 20. The y-intercept represents the number of postcards when she began collecting and the slope of the line represents the number of postcards added each vacation.
Step-by-step explanation:
In order to solve this equation, it is important to recall slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept. Now, let's look at the equation given and compare it to slope-intercept form.
y = 8x + 20y = mx + bWe can conclude that 8 is the slope of the line due to the fact that it has replaced m and we can also conclude that 20 is the y-intercept due to the fact that it has replaced b. Furthermore, we know from the description provided that Jacquie began with 20 postcards, and since we now know that these 20 postcards are the y-intercept, we can fill that in as our answer. This same logic can be applied with the 8 additional postcards added each vacation since we now know it is the slope of the equation.

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
