how does the graph of g(x) = (x - 3)^3 - 2 differ from the group of f(x) = x^3?
A. g is shifted 3 units right and 2 units up.
B. g is shifted 3 units right and 2 units down.
C. g is reflected across the y-axis.
D. g is rotated 90* clockwise.
Answer:
B
Step-by-step explanation:
f(x) = x³
g(x) = (x - 3)³ - 2
The inside of the parenthesis represents a horizontal shift
If the number operation being done to x inside of the parenthesis is adding ( or if the number is positive ) then the graph will shift to the left. If the operation being done inside of the parenthesis to x is subtraction ( or if the number is negative ) then the graph will shift to the right.
The operation being done is subtraction therefore it will shift to the right. So it will go 3 units to the right.
the number on the outside works like a y intercept. if it's positive it goes up, if it's negative it goes down. the number is -2 so it will go down 2 units
we can conclude that g is shifted 3 units right and 2 units down
the answer is B
Your cellphone company charges a $18 monthly fee, plus $0.11 per minute of talk time. One month your cell phone bill was $70.80. How many minutes did you spend talking on the phone that month?
Answer:
480 minutes would be the answer
Step-by-step explanation:
Answer:
480 minutes
Step-by-step explanation:
We can write this relationship as [tex]y=0.11x+18[/tex] and then solve for x when y=70.80:
[tex]y=0.11x+18\\\\70.80=0.11x+18\\\\52.80=0.11x\\\\480=x[/tex]
Therefore, you spent 480 minutes talking.

A 440 wire is cut into three pieces the second piece is two times as long as the first the third piece is four times as long as the second how long is each piece
Step-by-step explanation:

A bicycle wheel has a circumference of 62 inches. Find the diameter of the wheel. If necessary, round to the tenths place. 39. 5 inches 19. 7 inches 15. 5 inches 9. 9 inches.
Answer:
19.7 inches
Step-by-step explanation:
circumference of a circle = 2πr
62 = 2*22/7 *r
r = 62 * 7 / 44 = 9.86
diameter = 2* r
= 2* 9.86
= 19.7 inches
2. One bag of fertilizer will cover 400 square feet. Find how many bags should be purchased to cover a garden that is
35 feet by 75 feet.
35*75 is
2625
2625/400 is
6.5625
Since you cannot have a decimal amount of a bag, you should purchase
(rounding)
7 bags of fertilizer
Answer:
7 bags
Step-by-step explanation:
First thing you need to do is figure out the area of the garden. Area=length×width, so just put in your numbers, 35×75=2625 square feet. One bag covers 400 feet, so you divide the area by 400, 2625÷400=6.5625. You can't buys 6.5625 bags of fertilizer, so you have to go up to the next whole number which is 7.

probability (a) = 25%
probability (b) = 60%
determine probability (a and b)
Answer:
85%
Step-by-step explanation:
P(a) = 25%=1/4
P(b) = 60%=3/5
P(a and b) = 1/4 + 3/5 = 5+12/20 = 17/20 = 85%
Answer:
The probability of A and B is 85%
Step-by-step explanation:
It is 85% because 25% is 0.25 or 25/100(1/4), and 60% is 0.6 or 6/10(3/5). 0.6+0.25=0.85 and to convert it back to a percentage you need to times 100%. 0.85x100%=0.85x100 with a percentage symbol =85%.

Answer:
(b) 16 ft²
Step-by-step explanation:
The area of a trapezoid is given by the formula ...
A = 1/2(b1 +b2)h . . . . . where b1, b2 are the base lengths, h is the height
Using the values shown on the diagram, we find the area to be ...
A = 1/2(3 ft + 5 ft)(4 ft) = (1/2)(8 ft)(4 ft) = 16 ft²
The area of the trapezoid is 16 ft².

[tex] \frac{5}{3} + \frac{4}{6} = [/tex]
.................
Answer:
[tex]\frac{7}{3} =2\frac{1}{3}[/tex]
Step-by-step explanation:
For the problem:
[tex]\frac{5}{3} +\frac{4}{6} = ?[/tex]
The Least Common Multiple (LCM) of 3 and 6 is 6. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:
[tex]\frac{5}{3} +\frac{4}{6} =\frac{5*2}{3*2} +\frac{4}{6} =\frac{10}{6} +\frac{4}{6}[/tex]
Now that the fractions have like denominators, add the numerators:
[tex]\frac{10}{6} +\frac{4}{6} =\frac{10+4}{6} =\frac{14}{6}[/tex]
The Greatest Common Factor (GCF) of 14 and 6 is 2. The result can be simplified by dividing both the numerator and denominator by 2.
[tex]\frac{14}{6} =\frac{14/2}{6/2} =\frac{7}{3}[/tex]
7 ÷ 3 = 2R1, therefore:
[tex]\frac{7}{3} =2\frac{1}{3}[/tex]
Pankaj borrows rupees 57,000 to buy a used car and is charged the rate of interest 6% per annum. if the term of his borrowing is 4 years, how much interest does he pay?
Rs.13680 is the answer.
Step-by-step explanation:-
Given-
• Principal (P) = Rs.57,000
• Rate (r%) = 6%
[tex]→ \frac{6}{100} [/tex]
[tex]→ 0.06[/tex]
• Time (n) = 4 years
Applying Interest formula,
[tex]→In=P \times R \times T[/tex]
[tex]→57,000 \times 0.06 \times 4[/tex]
[tex]→Rs.13680[/tex]
Hence, the interest is Rs.13680

Using postulates and/or Theorems learned in unit 1, determine weather ABC ~ AXY. show all your work and explain why the triangles are similar and why they are not.
Answer:
AX / AB = 6/18 = 1/3
AY / AC = 10/25 = 2/5
They are not similar because the two ratios is not the same.
Step-by-step explanation:
I'm not really sure okay!
Note that [tex]\frac{AX}{AB}=\frac{6}{24} =\frac{1}{4} ,and\frac{AY}{AC}=\frac{10}{35}=\frac{2}{7}.[/tex]
Because the ratio of the lengths of corresponding sides of the triangles are not equal, the triangles are not similar.
