Answer:
x = 1
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]
Given
[tex]log_{64}[/tex] 8 = [tex]\frac{x}{2}[/tex] , then
8 = [tex]64^{\frac{x}{2} }[/tex]
note 64 = 8² , so
8 = [tex](8^2)^{\frac{x}{2} }[/tex] = [tex]8^{x}[/tex]
Since bases on both sides are equal, both 8 then equate the exponents
x = 1

How does the graph of the function g(x)=7^x+5 differ from the graph of f(x)=7^x?
Answer:
see explanation
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Given g(x) = [tex]7^{x}[/tex] + 5
Then this is the graph of f(x) shifted vertically up by 5 units
Graph the line below:
y = -2x + 7
Answer:
Below.
Step-by-step explanation:
When x = 0, y = 7
and when y = 0, x = 3.5.
So plot the 2 points (0, 7) and (3.5, 0) on the grid and draw a straight line through these 2 points.
Connect these points [tex](\frac{7}{2} ,0)[/tex] and [tex](0, 7)[/tex] through a straight line. And this line represents [tex]y = -2x + 7[/tex].
How to graph a line?To graph a line we follow the following steps:
Find the y-intercept = b of the equation y = mx + b.Plot the y-intercept. The point will be (0, b).Plot the x intercept. The point will be (x, 0). Connect those two points with your line.According to the given question.
We have a equation of line
[tex]y = -2x+7[/tex]
The above equation of line is already in the slope intercept form.
So, the graph the line y = -2x + 7.
We first find the y intercept.
On comparing the above equation with y = mx + b, we get y = 7.
⇒ The point (0, 7) is our y intercept.
Therefore, we plot the y intercept or mark the point (0, 7) on graph.
Then we find the x intercept.
[tex]0 = -2x + 7[/tex] ( substitute y = 0)
⇒[tex]x = \frac{7 }{2}[/tex]
⇒ ([tex]\frac{7}{2}[/tex], 0 ) is our x intercept.
Connect these points [tex](\frac{7}{2} ,0)[/tex] and [tex](0, 7)[/tex] through a straight line. And this line represents [tex]y = -2x + 7[/tex].

Answer:
a) 24 square feet
b) $12
Step-by-step explanation:
You want to make a retangular prism out of cardboard. The base is 3 feet by 4 feet. The height is 2 feet. You have $5.00 and cardboard costs .10 per square foot.
a) What is the surface area of the rectangular prism?
Length × Width × Height
3 feet × 4 feet × 2 feet
= 24 square feet
b).How much will it cost to make the rectangular prism out of cardboard?
1 ft² = $0.5
24 ft² = x
Cross Multiply
x = 24ft² × $0.5/1 ft²
x = $12
It would cost $12 to make the rectangular prism out of the cardboard. You do not have sufficient money to make it

Answer:
<B = 40degrees
x = 9
Step-by-step explanation:
Find the diagram attached. From the diagram, <A = <B (corresponding angle)
5x - 5 = 3x+ 13
5x - 3x = 13 + 5
2x = 18
x = 18/2
x = 9
Since <B = 3x+13
<B = 3(9) + 13
<B = 27 + 13
<B = 40degrees

Type the correct answer in each box. If necessary, use / for the fraction bar(s).
Given:
The values are [tex]a=0.\overline{6},b=0.75[/tex].
To find:
The values of [tex]ab[/tex] and [tex]\dfrac{a}{b}[/tex].
Solution:
We have,
[tex]a=0.\overline{6}[/tex]
[tex]a=0.666...[/tex] ...(i)
Multiply both sides by 10.
[tex]10a=6.666...[/tex] ...(ii)
Subtracting (i) from (ii), we get
[tex]10a-a=6.666...-0.666...[/tex]
[tex]9a=6[/tex]
[tex]a=\dfrac{6}{9}[/tex]
[tex]a=\dfrac{2}{3}[/tex]
And,
[tex]b=0.75[/tex]
[tex]b=\dfrac{75}{100}[/tex]
[tex]b=\dfrac{3}{4}[/tex]
Now, the product of a and b is:
[tex]ab=\dfrac{2}{3}\times \dfrac{3}{4}[/tex]
[tex]ab=\dfrac{1}{2}[/tex]
The quotient of a and b is:
[tex]\dfrac{a}{b}=\dfrac{\dfrac{2}{3}}{\dfrac{3}{4}}[/tex]
[tex]\dfrac{a}{b}=\dfrac{2}{3}\times \dfrac{4}{3}[/tex]
[tex]\dfrac{a}{b}=\dfrac{8}{9}[/tex]
Therefore, the required values are [tex]ab=\dfrac{1}{2}[/tex] and [tex]\dfrac{a}{b}=\dfrac{8}{9}[/tex].

The volume of a cone is 763.02 cubic inches. The radius and height of the cone are equal. What is the radius of the cone?
Answer:
The radius of the cone is 9cm
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cone
The volume of a cone is expressed as
V=1/3(πr²h)
We were told that the radius r and the height h are equal
I.e r=h
Substituting h=r in the formula we have
V= 1/3(πr²*r)
V =1/3(πr³)
To find the radius r let us substitute our given 763.02cm³ (note we assume unit in cm)
763.02= 1/3(3.142r³)
763.02= (3.142r³)/3
763.02*3=3.142r³
2289.06=3.142r³
r³=2289.06/3.142
r³= 728.54
r= ³√728.54
r= 8.99cm
≈r= 9cm
