Answer:
Answer is n^4
Step-by-step explanation:
You add the exponent when they are multiplying and have the same base
Answer:
n^4
Step-by-step explanation:
n^3 just means nxnxn and now, you are going to multiply that by another n. So it will become nxnxnxn which is essentially just n^4. Also, you should keep in mind that when you multiply a number by another number that has exponents in it but has the same base, you can just add their exponents. For example, n is actually just n^1 and when you multiply it by n^3 you can just add the one and the three to get 4. Which will give you n^4. Another example is if you have 6^5 multiplied by 6^3, you can just add the exponents and put that on the base to get 6^8. This works because 6^5 is just (6x6x6x6x6) and 6^3 is just (6x6x6) and when you multiply all of them you get 6^8 (6x6x6x6x6x6x6x6) I hope the last part made sense. If it didn't, you can just use the nxnxnxn logic instead. The last part was a little hard from me to explain.

Chad and Eric left a 20% tip after having lunch at a restaurant. Chad's lunch cost $10.
Which equation can you use to find x, the cost of Eric's lunch?
Group of answer choices
A) 0.2(x + 10) = 5
B) 0.2x = 10 + 5
C) 0.2x + 5 = 10
D) 0.2x + 10 = 5
Answers
Answer:
The equation used to find x, the cost of Eric's lunch is [tex]\mathbf{0.2(x+10)=5}[/tex]
Option A is correct option.
Step-by-step explanation:
Chad and Eric left a 20% tip after having lunch at a restaurant.
Cost of Chad Lunch = $10
Let Cost of Eric's lunch = x
So, Total cost of Chad and Eric's Lunch = x+10
Now, they left a 20% tip
it means 20% of total cost of lunch
20% can be written as 0.2
So, 0.2 of total cost of lunch is tip of the meal
We can write: 0.2 of (x+10)
or 0.2(x+10)
Looking at options, considering $5 was the amount of tip, the final equation will be:
[tex]0.2(x+10)=5[/tex]
So, the equation used to find x, the cost of Eric's lunch is [tex]\mathbf{0.2(x+10)=5}[/tex]
Option A is correct option.

If a university accepts only 75 percent of applicants, and only 45 percent of accepted applicants enroll, what percentage of total applicants enroll
Answers
Answer = 33.75%
Step-by-step explanation: It might be intuitive to think of percentages as a part of 100. If only 75 percent of 100 applicants are accepted. Then 75 people are accepted. We now need to find 45 percent of 75 people. In order to do this we need to convert 45 percent into its decimal form and multiply it by 75.
.45*75 = 33.75 of the original 100 Applicants have enrolled.

Answer: B. 8n^18
Step-by-step explanation:
From the question, we are informed that the area of a square is 64n^36. The length of one side of the square would be calculated as the square root of the value given. This will be:
= ✓64n^36
= ✓64 × ✓n^36
= 8 × (n^36 × 1/2)
= 8 × n^18
= 8n^18
Therefore, the correct option is B.
Toby picks a 4-digit number.
It is larger than 7999 and it is a multiple of 5.
How many different numbers could he have picked?
Answers
Answer:
Total different numbers = 400
Step-by-step explanation:
Assume;
Smallest number bigger than 7999( multiple of 5) = 8,000
largest 4 digit number multiple of 5) = 9,995
Computation:
a = 8,000
d = 5
an = 9,995
an = a + (n-1)d
9,995 = 8,000 + (n-1)5
1,995 = (n-1)5
399 = n-1
n = 400
Total different numbers = 400
Transform the quadratic function defined by y=ax2+bx+c into the form y=a(x-h)2+k 1.Y=x2-6x-3 2.Y=5x2-20x-5
Answers
Answer:
1) y = (x-3)²-12
2) y = 5(x-2)²-9
Step-by-step explanation:
Given the quadratic expressions
y=x²-6x-3
We are to transform it in the form y=ax²+bx+c
y=(x²-6x)-3
Complete the square of the expression in parenthesis
y = (x²-6x + (6/2)² - (6/2)²)-3
y = (x²-6x+3²-3²)-3
y = (x²-6x+9-9)-3
y = (x²-6x+9)-12
y = (x²-3x-3x+9)-12
y = x(x-3)-3(x-3)-12
y = (x-3)(x-3)-12
y = (x-3)²-12
Hence the transformation is y = (x-3)²-12 where a = 1 and k = -12
For the quadratic equation
y=(5x²-20x)-5
y = 5(x²-4x)- 5
Complete the square of the expression in parenthesis
y = 5(x²-4x+4-4)- 5
y = 5(x²-4x+4)-9
y = 5(x-2)²-9
Hence the transformation is y = 5(x-2)²-9 where a = 5 and k = -9

Bus A leaves the station every 30 mins bus b leaves the station every 20 mins at 10 am both buses leave the station together work out the next time both buses leave at the same time
Answers
Answer: 11am
Step-by-step explanation:
To solve this, we have to calculate the lowest common multiple of 20 and 30. This will be:
20 = 20, 40, 60, 80, 100
30 = 30, 60, 90, 120, 150.
Here, the lowest common multiple is 60.
Therefore, we add 60 minutes to 10am. This will be:
= 10am + 1 hour
= 11 am
The next time that both buses leave at the same time would be 11am

the sum of the interior angles of a polygon is 1980°.how many sides has the polygon
Answers
Answer:
sum of interior angle of polygon = (2N-4) X 90 where N =number of sides
so (2N-4)x90=1980
therefore N=13.
therefore polygon has 13 sides
Answer:
To know how many sides has this polygon, knowing the sum of their interior angles, we can use this expression:
b = (n-2) * 180
Where b is the sum of the interior numbers and n the number of sides.
Knowing this, we can replace, as we kno w it
b = (n-2)) * 180
1980 = (n-2)*180
We can know solve the equation
We can use this distributive property to operate the parenthesis, which says that if we find this expression a(b+c), we can operate doing ab+ac, and, if we substract, we can also use it, as a(b-c) = ab-ac
1980 = (n-2)*180
1980 = 180n - 180*2 = 180n - 360
1980 = 180n - 360
1980 + 360 = 180n
[tex]\frac{1980+360}{180} = n.[/tex]
13 = n
So we know the polygon will have 13 sides..
Choose a value for b so that the relation below is not a function.
Answers
Answer:
B. -2
Step-by-step explanation:
A relation that is not a function would have one x-value having two different corresponding y-values.
If we choose -2 to represent b I the relation, the relation would not be a function. This is because, we there would be two different y-values, 8 and 1, that are assigned to one x-value, which is -2 ==> (-2, 8) and (-2, 1).

A library had 570 books when it first opened. A year later, the number of books increased by 30%. How many books were there in the library a year later?
Answers
Answer: There were 741 books in the library a year later.
Step-by-step explanation:
Given: Total books in library = 570
Number of books increased by 30%.
One year later, Number of books in the library = (Total books in library) + 30% x (Total books in library)
= 570 + (0.30) x (570)
= 570 (1+0.30)
= 570 (1.30)
= 741
Hence, there were 741 books in the library a year later.
