Answer:
5^15
Step-by-step explanation:
Using the laws of powers, you can multiply 5^3 out of its bracket and get 5^27. Then, once again, using the laws of powers, you can get 5^15 by subtracting the powers.
Answer:
(5^3)^9/5^12 is equivalent to 5^15
Step-by-step explanation:
Begin by simplifying (5^3)^9
To make it much easier, apply the power rule. (a^x)^y = a^xy)
Multiply 3 x 9 = 27... so we get 5^27
Next, instead of dividing 27/12, which will result in a decimal..you must do 27-12, which is applying the quotient rule. (a^x / a^y = a^x-y)
5^27/5^12 = 5^27-12 = 5^15
( When I use /, it signifies to divide.)
So, (5^3)^9/5^12 is equivalent to 5^15! Hope this helps! :D

A. C(x) = 35x B. C(x) = 35x+245 C. C(x) = 35(x+245) D. C(x) = 35 + (x+245)
Answers
The function that represents the total cost, c(x), of this kayak tour package for x club members is 245 + 35x
How to calculate the total cost on a package?According to the given question, we have the following parameters
Amount charged on tour guide = $245
Let the total number of club members charged be "x", such that if the company charges $35 per person, the total cost on "x" members will be 35x
Determine the total costTotal cost = Amount charged on tour guide + cost of "x" members
Total cost = 245 + 35x
Hence the function that represents the total cost, c(x), of this kayak tour package for x club members is 245 + 35x

x2 + 8x + 19 = 0 What is the equivilent that results from completing the square?
Answers
Answer:
[tex](x+4)^2+3=0[/tex]
Step-by-step explanation:
Hey there!
Standard form is what this equation is in
Standard form is this: [tex]ax^2+bx+c[/tex]
So order to complete the square, you need to take the [tex]b[/tex] term out of the equation, divide it by two, and then square it
In this case, the [tex]b[/tex] term is 8
We need to divide 8 by 2 ---> 4
Then square 4 ---> 16
So now you should add 16 to both sides
[tex]x^2+8x+16+19=16[/tex]
Now you can simplify the LHS
[tex](x+4)^2 +19=16[/tex]
Now you subtract 16 from both sides
[tex](x+4)^2+3=0[/tex]
So this is as far as you can go since you cannot take the square root of a negative number

Which equation is represented by the graph below?
i’ll make brainlyesttttt
Answers
Answer:
y=e^x - 4
Step-by-step explanation:
The log functions decrease with increasing x. The line shown increases as x increases, so it must be one of the two e^x equations. We can decide which one by calculating which equation povides the correct values to match the two points the curve crosses the y and x axes.
The graph shows the line crossing the y axis at -3 (0,-3)
It shows it crossing the x axis at a little over 1, perhaps 1.4 (1.4,0).
When x=0, e^0 = 1.
Look at the point (0,-3):
We know the e term will be 1 (e^0 = 1), so for y to be -3, we need to subtract 4: The form e^x - 4 would yield a value for y, when x is 0, of y = 1 - 4 or -3.
Check the other point (1.4,0):
y = e^1.4 is equal to 4.00
y = 4.00 - 4
y = 0
This point is also correct (1.4,0)
The correct equation is y=e^x - 4

Yes, at positive x coordinates
Yes, at negative x coordinates
Yes, at negative and positive x coordinates
No, they will not intersect
Answers
Answer:
Yes, at positive x coordinates
Step-by-step explanation:
Find the equation of g(x)
Given ordered pairs of g(x): (-1, -22) (0, -20) (1, -18)
[tex]\sf let\:(x_1,y_1)=(0,-20)[/tex]
[tex]\sf let\:(x_2,y_2)=(1,-18)[/tex]
[tex]\sf slope\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-18-(-20)}{1-0}=2[/tex]
Point-slope form of linear function: [tex]\sf y-y_1=m(x-x_1)[/tex]
[tex]\implies \sf y-(-20)=2(x-0)[/tex]
[tex]\implies \sf y=2x-20[/tex]
Substitute the equation of g(x) into the equation of the circle and solve for x
Given equation: [tex]y^2+x^2=100[/tex]
[tex]\implies (2x-20)^2+x^2=100[/tex]
[tex]\implies 4x^2-80x+400+x^2=100[/tex]
[tex]\implies 5x^2-80x+300=0[/tex]
[tex]\implies x^2-16x+60=0[/tex]
[tex]\implies x^2-10x-6x+60=0[/tex]
[tex]\implies x(x-10)-6(x-10)=0[/tex]
[tex]\implies (x-6)(x-10)=0[/tex]
Therefore:
[tex](x-6)=0 \implies x=6[/tex]
[tex](x-10)=0 \implies x=10[/tex]
So the linear function g(x) will intersect the equation of the circle at positive x coordinates.

What is the median, first quartile third quartile and interquartile of 38 46 55 56 558 59 61 65 67 75
Answers
Answer:
Median = 58.5
Q1 = 55
Q3 = 65
Interquartile = 10
Step-by-step explanation:
first let’s correct the data set :
It’s 38 46 55 56 58 59 61 65 67 75 not 38 46 55 56 558 59 61 65 67 75
Data set : 38 46 55 56 58 59 61 65 67 75
Median:
After we put Our data set from Smallest to largest
we define the median as the middle number of the data set but our set consists of an even number which is 10
In this case the median is the average of the two middle numbers which are the 5th and 6th numbers
38 46 55 56 [58 59] 61 65 67 75
Then
Median = (58+59)/2 = 117/2 = 58.5
quartile 1 : It’s just the median of the lower set of numbers which means it’s the median of : 38 46 55 56 58
Then Q1 = 55 because it’s the middle number.
quartile 3 : It’s just the median of the upper set of numbers which means it’s the median of : 59 61 65 67 75
Then Q3 = 65 (Easy to spot)
Interquartile = Q3 - Q1 = 65 - 55 = 10

The height of a triangle is 4 feet less than the length of its base, b. The area of the triangle is 30 square feet.
Find the base and the height of the triangle.
Answers
Answer:
b = 10 ft , h = 6 ft
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
let base = b theh height h = b - 4
given A = 30 , then
[tex]\frac{1}{2}[/tex] b(b - 4) = 30 ( multiply both sides by 2 to clear the fraction )
b(b - 4) = 60 ← distribute parenthesis on left side by b
b² - 4b = 60 ( subtract 60 from both sides )
b² - 4b - 60 = 0
(b - 10)(b + 6) = 0
equate each factor to zero and solve for b
b - 10 = 0 ⇒ b = 10
b + 6 = 0 ⇒ b = - 6
however, b > 0 , then b = 10
and h = b - 4 = 10 - 4 = 6
then base is 10 ft and height is 6 ft
