Answer:
15.71 cm
Step-by-step explanation:
Equation for the circumference of a circle: 2πr or dπ where r is the radius & d is the diameter.
5*π = 15.71
Answer:
15.71 cm
Step-by-step explanation:
Use the circumference formula, C = 2[tex]\pi[/tex]r
Since the radius of half of the diameter, the radius will be 2.5 cm
Plug in the radius into the formula and solve:
C = 2[tex]\pi[/tex]r
C = 2[tex]\pi[/tex](2.5)
C = 15.71
So, the circumference of the circle is approximately 15.71 cm
How to solve absolute value
2|x+9|+3=7
Answer:
x = -7, -11
Step-by-step explanation:
2|x+9|+3 = 7
subtract 3 from both sides of equation
2|x+9| = 4
divide 2 from both sides of equation
|x+9| = 2
Absolute values:
x+9 = 2 and x+9 = -2
x = -7 and x = -11

Answer:
h(3) = -4
h(-3) = -16
Step-by-step explanation:
The formula is h(x)= 2x-10. So you have to plugin 2x-10 into h(3). Same thing for h(-3).
h(3) = 2*3-10
h(3) = -4
h(-3) = 2*-3-10
h(-3) = -16

Can somebody help me on 12??
Answer:
Step-by-step explanation:
a. The blue curve represents the puppies weight because the graph only shows 2 years, humans aren't done growing until they are 14-20. You can see the pink line is still going up, which makes sense for a human. Dogs reach close to adult size after 1 year, and may grow a little more after, but it remains steady.
b. If the graph is to scale, then it appears this puppy has almost finished growing just after one year. It grew the fastest in the first 6 months, and then a little more the next 6, and it looks like it was finished growing after a little over a year.
The baby was a little slower to start, it looks like there was less growth the first 6 months, then the growth took off and the baby is continuing to grow quickly going off the chart before the 2 year mark.
At about 3 months it looks like the baby and puppy weigh the same, but the puppy continues to grow a little faster, at 8 months it looks like they weigh the same again, but the baby takes off in weight and the puppy only gains a little more.
Bill spent $60 of fertilizer and weed killer for his lawn. Each pound of fertilizer cost 75 cents, and
each ounce of weed killer cost $2.50. Which of the following equations represents the relationship
between the number of pounds of fertilizer Bill bought, x, and the number of ounces of weed killer
he bought, y?
a) y = -3/10x + 24
b) y = -3/4x + 60
c) y = -5/2x + 60
d) y = -10/3x + 80
Answer:
a) y = -3/10x + 24.
Step-by-step explanation:
2.5y + 0.75x = 60
2.5y = -0.75x + 60
Divide through by 2.5:
y = -3/10x + 24.
Consider the function, f (x) = 2x – 1
Use the above function to complete the following table.
Answer:
x f(x)
1 1
0 -1
-1 -3
2 3
Step-by-step explanation:
∵ The given function is f(x) = 2x - 1
∵ The table has the values of x
→ Substitute the values of x in the function to find the values of f(x)
∵ x = 1
→ Replace every x in the function by 1
∴ f(1) = 2(1) - 1
∴ f(1) = 2 - 1
∴ f(1) = 1
∵ x = 0
→ Replace every x in the function by 0
∴ f(0) = 2(0) - 1
∴ f(0) = 0 - 1
∴ f(0) = -1
∵ x = -1
→ Replace every x in the function by -1
∴ f(-1) = 2(-1) - 1
∴ f(-1) = -2 - 1
∴ f(-1) = -3
∵ x = 2
→ Replace every x in the function by 1
∴ f(2) = 2(2) - 1
∴ f(2) = 4 - 1
∴ f(2) = 3
The missing values in the table are 1, -1, -3, 3
x f(x)
1 1
0 -1
-1 -3
2 3
The four needed values for right column of table are: 1, -1, -3, 3
The completed table will look like:
[tex]\begin{center}\begin{tabular}{ c c } x & f(x)\\ 1& 1 \\ 0 & -1\\-1 & -3\\ 2& 3\end{tabular}\end{center}[/tex]
Given function is:
f(x) = 2x - 1
Cases:
1. x = 1
f(1) = 2 - 1 = 1
2. x = 0
f(0) = 0 - 1 = -1
3. x = -1
f(-1) = -2 - 1 = -3
4. x = 2
f(2) = 4 - 1 = 3
Thus the four needed values for right column of table are: 1, -1, -3, 3

A local cable tv company charges a base fee of $35 per month plus an additional
$12 per month for each additional premium channel. The monthly charges can be
represented with equation C = 35 + 12p, where p is the number of premium channels
and C is the total monthly charge.
A. What would be the monthly charge for the service if you are watching 5
premium channels? Show how you found your answer.
Answer:
95$
Step-by-step explanation:
Since there are 5 premium channels, we multiply the rate of charges by the number of premium channels to get the extra payment.
5 channels x 12$ per channel = 50$
Now we add this to 35 since C= 35 + 12 or 35 plus the premium channel costs
35$ + 50 = 95$

Suppose there are 20 people in a room and the mean amount of cash held by these 20 people is $14.50 per person. If two people enter the room carrying $4.00 and $5.00 respectively, what does the mean amount of cash in the room become? Give your answer in dollars and cents; that is, precise to two decimal places.
Answer:
13.59
Step-by-step explanation:
The calculation of amount of cash in the room is shown below:-
[tex]\$14.50 = \frac{\Sigma xi}{20}[/tex]
= 20 × $14.50
= $290
Now, the new sum is
= ∑xi + $4.00 + $5.00
= $290 + $4.00 + $5.00
= $299
Total person in the room is
= 20 + 2
= 22
So,
Mean amount of cash in the room = New sum ÷ Total person in the room
= $299 ÷ 22
= 13.59

simplify (a+b) (a+2ab) + (2a-b) (a-b)
Step-by-step explanation:
since im typing it out its neater to seperately do left side expression and right side expression
(a+b)(a+2ab) = a(a+2ab) + b(a+2ab) (expansion of terms)
=a^2 +2a^2b + ab + 2ab^2 (remember order of algebraic terms doesnt matter so for instance ab=ba)
other side
(2a-b)(a-b) = 2a(a-b) -b(a-b)
=2a^2 -2ab -ab +b^2 (remember -b x -b = b^2, negatives cancel out when they multiply by each other)
if you want to present this on paper, you would have done the both expansions in one line, to reach this line
.
.
.
= a^2 + 2a^2b + ab + 2ab^2 + 2a^2 -2ab -ab +b^2
=3a^2 + b^2 -2ab + 2a^2b + 2ab^2

Answer:
27
Step-by-step explanation:
Step 1: Define
f(x) = x - 14
g(x) = x² + 2x + 12
Step 2: Find g(f(x))
g(f(x)) = (x - 14)² + 2(x - 14) + 12
g(f(x)) = x² - 28x + 196 + 2x - 28 + 12
g(f(x)) = x² - 26x + 180
Step 3: Find g(f(9))
g(f(9)) = 9² - 26(9) + 180
g(f(9)) = 81 - 234 + 180
g(f(9)) = -153 + 180
g(f(9)) = 27
