Graph f(x) = -2/3x-3
PLS ANSWER AND SHOW HOW ITS GRAPHED
Answer:
Graph and solved
Step-by-step explanation:
The variable f varies inversely as the square root of g. When f = 4, g = 4. Jordan’s work finding the value of f when g = 100 is shown: f = k 4(4) = k 16 = k f = 16 f = 16 10f = 16 f = 1.6 What is the first error, if any, in Jordan’s work?
Variation can be direct, inverse or jointly
Jordan's first error is that he incorrectly calculated the value of proportionality constant
From the question, we understand that f varies directly as the square root of g.
This variation is represented as:
[tex]\mathbf{ f\ \alpha\ \frac{1}{\sqrt{g}}}[/tex]
Express as a equation
[tex]\mathbf{ f\ \ =\ k\frac{1}{\sqrt{g}}}[/tex]
When f = 4, k = 4.
So, we have:
[tex]\mathbf{ 4\ \ =\ k\frac{1}{\sqrt{4}}}[/tex]
[tex]\mathbf{ 4\ \ =\ \frac{k}{2}}[/tex]
Multiply both sides by 2
[tex]\mathbf{ k = 8}[/tex]
When g = 100, we have:
[tex]\mathbf{ f\ \ =\ k\frac{1}{\sqrt{g}}}[/tex]
[tex]\mathbf{ f\ \ =\ 8 \times \frac{1}{\sqrt{100}}}[/tex]
[tex]\mathbf{ f\ \ =\ 8 \times \frac{1}{10}}[/tex]
[tex]\mathbf{ f\ \ = 0.8}[/tex]
This means that, Jordan incorrectly calculated the value of proportionality constant

Find the value of a/b when a=$13. 93 and B=0. 07
Thank you.
Answer:
10
Step-by-step explanation:
A = 7, B = 2
7 = 2 * 3 + 1
7 mod 2 = 1
A = 8, B = 4
8 = 4 * 2 + 0
8 mod 4 = 0
A = 13, B = 5
13 = 5 * 2 + 3
13 mod 5 = 3
A = -16, B = 26
-16 = 26 * -1 + 10
-16 mod 26 = 10
solve for x. round to the nearest tenth of a degree, if necessary
the x-intercept of the graph of f(x)=3log(x-5)+2 is:
Answer:
C
Step-by-step explanation:
To find the x- intercept let f(x) = 0 , then
3log(x - 5) + 2 = 0 ( subtract 2 from both sides )
3log(x - 5) = - 2 ( divide both sides by 3 )
log(x - 5) = - [tex]\frac{2}{3}[/tex] , then
x - 5 = [tex]10^{-\frac{2}{3} }[/tex] ( add 5 to both sides )
x = [tex]10^{-\frac{2}{3} }[/tex] + 5 → C

is -19+ square root of 14 rational or irrational
Answer:
The answer is irrational.
Step-by-step explanation:
Any whole number +/- an irrational number will be irrational as well. Since [tex]\sqrt{14}[/tex]is irrational (it can't be expressed as a ratio of 2 whole numbers) the answer will also be irrational because you are adding it to 19 (a whole number).

Solve the Quadratic equation
8n²-56=48n
Answer:
n = {-1, 7}
Step-by-step explanation:
8n² - 56 = 48n
Subtract 48n from both sides
8n² - 48n - 56 = 0
Divide both sides by 8
n² - 6n - 7 = 0
Factor
alternately use the quadratic equation or complete the square
(n - 7)(n + 1) = 0
n = {-1, 7}

A 4.8 pound box of steaks costs $31.20. What is the cost per pound of steaks?
[tex] \frac{31.20}{4.8} = \\ [/tex]
[tex]6.5[/tex]
Thus the cost of steaks per pound is $ 6.5
Easy peasy....
The cost per pound of steaks is $6.5.
What is division?One type of operation in mathematics is division. We divide the phrases or numbers into the same number of components during this operation.
Given, a 4.8 pound box of steaks costs $31.20.
To find the cost per pound of steak:
We take the division of total cost and total pounds in weight.
That means,
Cost per pound of steaks
= 31.20 / 4.8
= 6.5.
Therefore, the cost is $6.5 per pound of steaks.
