The price of a new motorcycle is $4500, but the value of the motorcycle drops
by 11% each year. The function (t) = 4500 . 0.89 models this situation for v
dollars and tyears. What is a realistic domain for this situation?
.
A realistic domain for this situation is t = 0, 1, 2, 3, ... and consists of non-negative whole numbers representing the number of years after the motorcycle was purchased.
In the context of the situation, the domain represents the possible values for the number of years (t) for which the motorcycle's value is being calculated. Since the value of the motorcycle drops by 11% each year, it is reasonable to consider a domain that represents a finite number of years and includes only positive integers.
Typically, when modeling the depreciation of an asset like a motorcycle, it is reasonable to assume that the number of years (t) is a non-negative whole number (i.e., t = 0, 1, 2, 3, ...). The value at t = 0 represents the initial value of the motorcycle, and then each subsequent year represents the value after one more year of depreciation.
So, a realistic domain for this situation is t = 0, 1, 2, 3, ... and consists of non-negative whole numbers representing the number of years after the motorcycle was purchased.

The table shows a gym class's average results for boys and
girls participating in the long jump. Susan could jump no
farther than 4 inches more than the average distance for
females. Let j represent the distance that Susan could jump.
Write an inequality to represent the situation.
How far could Susan jump?
Susan can jump at most 104 in during the long jump
InequalityInequality is an expression that show the non equal comparison of two or more variables and numbers.
From the table, the average result for females = 8ft 4in = (8 * 12)in + 4in = 100 in
Since Susan could jump no farther than 4 inches more than the average distance for females, hence:
j ≤ 4 + 100
j ≤ 104 in
Susan can jump at most 104 in during the long jump

Expand and simplify 5(5x-2)+3(x-2)
Answer:
28x - 16
Step-by-step explanation:
multiply in the brackets
5 × 5x = 25x, 5 × -2 = -10, 3 × x = 3x, 3 × -2 = -6
25x - 10 + 3x - 6
simplify by collecting like terms
25x + 3x = 28x
-10 - 6 = -16
final answer = 28x - 16

What are the coordinates of B' if the origin is the center of dilation and the scale factor is 1/4?
Answer:
B' (1, 2 )
Step-by-step explanation:
Since the centre of dilatation is the origin then multiply the coordinates of B by the scale factor.
B (4, 8 ) → B' (4 × [tex]\frac{1}{4}[/tex] , 8 × [tex]\frac{1}{4}[/tex] ) → B' (1, 2 )
Answer:
1, 2
Step-by-step explanation:
When dealing with 1/4 scale factor, you just divide each point applicable by 4. Therefore:
(4, 8) > (1, 2)

Slope intercept form is y=mx+b.
Subtract 6x from both sides.
-8y=-6x-48
Then, simplify by dividing both sides by -8 and simplifying the fractions.
You end up with:
[tex]y=\frac{3}{4} x+6[/tex]
Ryan went to lunch with his family. The cost of their meal was $130.
They left a tip of 18% on the $130 and paid the sales tax of 9% on the
bill. What was the total cost of the meal?
Answer:
$167.20
Step-by-step explanation:
0.18 x 130 = $32.4 (this is what they tipped)
the total now stands at $153.4 before tax
now to work out the tax you multiply the decimal of 9% by $153.4
0.09 x 153.4 = 13.8
the total cost of the meal is $167.20
The total cost of the bill will be equal to $167.20
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Step-by-step explanation:
*0.45 can be put over 1. (All decimals can)
Multiply the numerator and denominator by 100, then simplify:
[tex] \frac{0.45 \times 100}{1 \times 100} = \frac{45 \div 5}{100 \div 5} = \frac{9}{20} [/tex]

Answer:
Step-by-step explanation:
∠AGB = ∠DGC {Vertically opposite angles}
∠AGB = 90°
∠AGE + ∠AGB + ∠BGF = 180 {Angles on straight line}
30 + 90 + x = 180
120 + x = 180
x = 180 - 120
x = 60°
Answer:
Solution,
Angle AGB=90°[Being vertically opposite angles]
Now we have,
30°+Angle AGB+x=180°
or,30°+90°+x=180°
or,x=180-30-90
Hence,x=60
