Answer: Both C and D are correct
Step-by-step explanation:
To remove the exponent from the v you need to square root both sides,
the exponent on the v is then canceled out giving you:
[tex]v=\sqrt{25/81}[/tex] or [tex]v=-\sqrt{25/81}[/tex]
Answer:
Both C & D are correct
Step-by-step explanation:
[tex]v^{2} =\frac{25}{81}[/tex]
Root both sides of the equation to remove the square.
[tex]v=\±\sqrt{\frac{25}{81} }[/tex]
[tex]v = \±\sqrt{\frac{5*5}{9*9} } \\v=\±\frac{5}{9}[/tex]
Therefore,
[tex]v=\sqrt{\frac{25}{81} } =-\sqrt{\frac{25}{81} }[/tex]

A local gym sells monthly memberships. The function f(x) = −x2 + 18x − 72 models the daily profit in dollars, where x is the number of memberships sold.
Determine the zeros, and explain what these values mean in the context of the problem.
x = 9, x = 18; The zeros represent the number of monthly memberships that produces a maximum profit.
x = 9, x = 18; The zeros represent the number of monthly memberships when no profit is made.
x = 6, x = 12; The zeros represent the number of monthly memberships that produces a maximum profit.
x = 6, x = 12; The zeros represent the number of monthly memberships when no profit is made.
Answer: the zeros are at (6,0) and (12,0) where no profit is made.
option D
Step-by-step explanation: you can find the zeros ( the x-intercepts), by either graphing out the function or factoring it.
in this scenario, there is no y increase, which means 0 profit.
please help me with this math question Graph this line using the slope and y-intercept:
Answer:
(8,1) (15,2) (22,3) (29,4) (36,5) (43,6)
Step-by-step explanation:
Answer:
Step-by-step explanation:
The equation y=7x+1 is written in slope intercept form. That would be:
y=mx+b
m is the slope
b is the y intercept, or where the line first is seen on the y axis.
Because b=1, the y intercept is 1.
Because m=7, the slope is 7.
STEP 1: GRAPH THE Y INTERCEPT.
Since b=1, the line crosses the y intercept when y=1. So graph y=1 on the coordinate plane.
STEP 2: GRAPH THE SLOPE
Do this by going up 7, then right 1. Because 7 is a positive number, you go up.

Answer:
[tex]-x + 9[/tex]
Step-by-step explanation:
Hello!
We want to combine any like terms and distribute the signs properly to the terms in the parentheses.
First, remove the parentheses by distributing the signs:
[tex]-(2x - 1) + 3(x + 4) - 2(x + 2)[/tex][tex]-(2x) - (-1) + 3(x) + 3(4) - 2(x) - 2(2)[/tex]The simplified form is [tex]-x + 9[/tex].
Another way to think about the negative sign is by replacing it with -1, so essentially you are multiplying the whole parentheses by -1.

The table shows the height in inches of 10 players on a college basketball team.
Answer:
A) The median is one of the values listed in the table
Step-by-step explanation:
The median is the middle number in an ordered data set. Since the number of date in the table is a even number, both 75 and 76 is the middle number. To find the median of an set of data that has an even number of sets, you just add the 2 middle numbers together and divide by 2. So like:
75+76=151
151/2=75.5
75.5 is the median but its not listed in the table, so A.

Answer:
38 degrees
Step-by-step explanation:
Since angles KLO and OLM are supplementary, they add up to 180 degrees
So, angle OLM is 180-134=46 degrees
Similarly, angles OMN and OML are supplementary, so they also add up to 180 degrees
So, angle OML is 180-84=96 degrees
You also know that the angles of a triangle sum up to 180 degrees
So, 46+96+x=180
180-142=38
x=38 degrees

The congruent triangles are solved and the measure of HI ≅ FG and the measure of DH ≅ BF
What are Congruent Triangles?Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the first triangle being constructed be ΔCBA
Let the second triangle being constructed be ΔDEL
Now , the measures of the corresponding sides of the congruent triangles will be in the same ratio
So , measure of HI ≅ measure of FG
And , the measure of DH ≅ the measure of BF
Hence , the ∠D is congruent to ∠B

Step-by-step explanation:Because the base is the same on the top and the bottom which is "9", you would either add or subtract the top and bottom exponent based on the arithmetic symbol used.
Because the arithmetic symbol division sign is used, you subtract the top exponent by the bottom giving you the answer nine to the power of two.

how much will you have to pay back in total if you borrowed $400 from the bank for a year at 12%
You would have to pay back $448 in total after one year.
What is the amount on the loan?The simple interest formula can be expressed as;
I = P × r × t
Where I is interest, P is principal, r is interest rate and t is time.
Given the parameters:
Principal P = $400 (the initial loan amount)
Rate r = 12% = 12/100 = 0.12
Time t = 1 year
Interest = ?
To determine the interest, we can use the above formula for simple interest:
I = P × r × t
Interest = $400 × 0.12 × 1
Interest = $48
Money to be paid back will be:
Amount = Principal + Interest
Amount = $400 + $48
Amount = $448
Therefore, the accrued amount to be paid is $448.

Answer:
30
Step-by-step explanation:
Since 5 and 6 are coprime, the least common multiple is their product, which is 30.
Answer: 30
Step-by-step explanation:
The least common multiple of two numbers, or LCM, is the smallest multiple that can divide evenly into both numbers. We can easily find the LCM by finding the primes that multiply into both numbers.
[tex]5=5\\ 6=2*3[/tex]
If there were any in common between the factorization of both numbers, we would only need to count it once. Since there weren't any, the smallest multiple of both numbers would be their product, 30.
Hence, the LCM of 5 and 6 is 30.

Step-by-step explanation:
x needs to be equal or less than 3. It doesn't say that x cannot be negative so any number 3 and below is fine.
Not solutions would be any number above 3 in value
The three solutions for the inequality are 1, 2, and 3.
And, the three numbers that are not solutions are 4, 5, and 6.
Used the concept of inequality that states,
A relation by which we can compare two or more mathematical expressions is called an inequality.
Given that,
The inequality is,
x ≤ 3
Now from the given inequality x ≤ 3,
The solution of the inequality is a number that is less or equal to 3.
Hence the possible three solutions for the inequality are,
x = 1, 2, 3
And, the three numbers that are not solutions are,
4, 5, and 6.

A batch of cookies is 24 cookies. It cost Courtney 134 dollars and 40 cents to make 10 batches of cookies.
How much does it cost Courtney to make 1 batch of cookies? Round to tenths places if necessary.
How much does it cost her to make 1 cookie? Round to the tenth place if necessary.
Answer:
13 dollars and 44 cents, 56 cents.
Step-by-step explanation:
134 dollars are 40 cents = 134.4 dollars.
10b = 134.4
b = 13.44
13 dollars and 44 cents
There are 24 cookies to a batch
24c = 13.44
c = 0.56.
so each cookie costs 56 cents
Answer:
13.44 to make 1 batch. 0.56 to make 1 cookie.
Step-by-step explanation:
If it cost 134.40 to make 10 batches, then you would divide that by 10 for how much it cost for 1 batch.
Then, 1 batch of 24 costs 13.44, you would divide it by 24 for the cost of 1 cookie.
