Answer:
radius: 4.2 cm
circumference: 26.376 cm^2
area: 55.3896 cm^2
Step-by-step explanation:
radius is half the diameter so 8.4/2 = 4.2
circumference: C = (2)(pi)(r) ---> (2)(3.14)(4.2) --> 26.376
area: (pi)(r ^2) --> (3.14)(4.2^2) --> 55.3896

Explain how to find vertical and horizontal asymptotes of a rational
equation.
Answer:
Step-by-step explanation: If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0).
If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

2n + 3 = -3.2 what is the answer to n
Answer:n=-3.1
Step-by-step explanation:
2n + 3 = -3.2
Subtract 3 on both sides
2n+3-3=-3.2-3
2n=-6.2
Divide 2 on both sides
2n/2=-6.2/2
n=-3.1
Answer:
n= -3.1

A number n is less than or equal to -7 or greater than 12.
Inequality: [ ] or [ ]
Graph the inequality.
Answer:
N ≤ -7 N > 12
Step-by-step explanation:
The inequality for the given statement is n≤-7 or n>12.
The given statement is a number n is less than or equal to -7 or greater than 12.
What is an inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values.
Now the inequality for the given statement is n≤-7 or n>12.
Graph for the obtained inequality is plotted, given below.
Therefore, the inequality for the given statement is n≤-7 or n>12.

Which is the quotient of 17. 51 +3.4?
O A. 5.07
O B. 5.15
OC. 5.21
D. 5.25 HELP THIS ENDS IN 10 MINUTES
Answer:
5.15
Step-by-step explanation:
17.51 / 3.4 = 5.15
Answer and Explanation
5.15 or [tex]\frac{17.51}{3.4}[/tex]__________________________________________________________
We can prove this is the answer by dividing both numbers.
__________________________________________________________
[tex]17.51[/tex] = [tex]\frac{1751}{100}[/tex]
[tex]3.4[/tex] = [tex]\frac{17}{5}[/tex] = [tex]3\ \frac{2}{5}[/tex]
__________________________________________________________
[tex]\frac{1751}{100}[/tex] [tex]\div[/tex] [tex]\frac{17}{5}[/tex] = [tex]?[/tex]
[tex]\frac{17.51}{3.4}[/tex] [tex]or[/tex] [tex]5.15[/tex]__________________________________________________________

A random two digit number (10-99) is drawn. Find each probability
1. p(32)
2. p(odd number)
3. p(a multiple of 5)
My teacher gave an assignment on this and didn't even teach how to do it.
Given that two digit numbers are used and one digit is drawn randomly.
Sample space = {10,11,...99}
n(S) = 90
32 is only one number favorable
Hence P(32) = 1/90
----------------------------
Odd numbers are exactly 45.
Hence prob (odd number) = 45/90 = 1/2
-------------------------------------
Multiples of 5 are 10,15,.....95
There are exactly 18 numbers.
Hence P(a multiple of 5) = 18/90 =1/5

A gallon of gasoline cost $3.00 last year, and now costs 5% more. What is the cost of a gallon of gasoline now?
a) 4.50
b) 3.15
c) 3.05
Answer:
B
Step-by-step explanation:
We know that Last year one gallon costs $3.00
and we also know that it costs %5 more this year.
We know that %100 is always the same which is $3.00
Then since we know $3.00 is %100, we can add %5 to %100 to get %105.
Then you multiply 105/100 by 3 then you will get 3.15 which is what B is
So that means our answer is B

Alexander is a stockbroker he earns 11% commission each week last week he sold $7000 worth of stocks how much did he make last week in commission if he averages the same amount each week how much did he make in commission in 2011
Answer:
the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively
Step-by-step explanation:
The computation of the amount that he makes last week and in the year 2011 is as follows:
= Sale value of the stocks × earning percentage × number of weeks in a year
= $7,000 × 11% × 52 weeks
= $40,040
hence, the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively
We simply applied the above formula so that the correct value could come

Divide 2 from both
=-3/1 or -3
Slope= -3
Finding y-intercept= y=mx+b
Choose any point on the line to plug in the x and the y then plug in the slope.
I choose (1,3)
3=-3×1+b
3=-3+b
Add 3 to both sides
6=b
Y-intercept=6
