Answer:
Initial Value: 19,900
Value after 11 years: 7953
Explanation:
The initial value of the car is its value at t =0. Therefore, to find this initial value, we put in t = 0 to get
[tex]v(0)=19,900(0.92)^0[/tex][tex]\boxed{v\mleft(0\mright)=19,900}[/tex]Hence, the initial value is $19,900.
Now, to find the value after 11 years, we put t = 11 into the equation and get
[tex]v(11)=19,900(0.92)^{11}[/tex]which gives (rounded to the nearest dollar)
[tex]\boxed{v\mleft(11\mright)=7953}[/tex]which is our answer!
Hence, the value after 11 years is $7953.

Find the slope-intercept equation of the line satisfying: Y-Int is 4 and goes through (1,8).
Answers
Let's recall that the slope-intercept equation of a line has the form
[tex]y=mx+b,[/tex]where "m" is the slope, and "b" is the y-intercept. We know that the y-intercept is 4; then, our equation becomes
[tex]y=mx+4.[/tex]The trick to finding the slope is to note that the point (1,8) lies on the line; namely, we can evaluate the equation of the line in this point:
[tex]8=m\cdot1+4.[/tex]Solving this equation for m, we get
[tex]\begin{gathered} 8=m\cdot1+4, \\ 8=m+4, \\ 8-4=m+4-4, \\ 4=m, \\ m=4. \end{gathered}[/tex]AnswerThe equation of the line satisfying the provided conditions is

6) Which type of transformation creates an image where the area of the shape changes? A) translations B) rotations C) reflections D) dilations
Answers
The transformation that changes the area of a shape is dilation (Option D)
Step by step explanation
Option A: Translation
A translation is a geometric transformation that moves every point of a figure, shape, or space by the same distance in a given direction. For this type, the image is congruent with the original shape.
Option B: Rotation
A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point. For this type, the image is congruent with the original shape.
Option C: Reflection
A reflection is a transformation where each point in a shape appears at an equal distance on the opposite side of a given line - the line of reflection. For this type, the image is congruent with the original shape.
Option D: Dilations
Dilation in math is a transformation that changes the size of a figure so it becomes larger or smaller without changing shape. This type changes the area since the area is the size of a figure.
Use a property to write a equivalent expression for 12 *(100-5). Which property did you use
Answers
Equivalent expression to the given expression 12 × ( 100 - 5 ) using distributive property multiplication over subtraction is given by
12 × 100 - 12 × 5.
As given in the question,
Given expression is equal to :
12 × ( 100 - 5 )
Simplify it using distributive property multiplication over subtraction to get its equivalent expression we have,
A × ( B - C ) = A × B - A × C
Here , Value of A = 12 , value of B = 100 , and value of C = 5
12 × ( 100 - 5 )
= 12 × 100 - 12 × 5
= 1200 - 60
= 1140
Therefore, equivalent expression to the given expression 12 × ( 100 - 5 ) using distributive property multiplication over subtraction is given by
12 × 100 - 12 × 5.

This problem is about coefficients.
It's important to know that a coefficient is a number used to multiply a variable. In other words, coefficients are all numbers placed in front of a variable.
Being said that, in this case, coefficients are 12 and 2, because these numbers multiply a variable.
Therefore, the right answer is 12 and 2.The citizens of a city were asked to choose their favorite pet. The circle graph shows how the citizens answered the questions, how many chose hamsters, birds, or fish.
Answers
To find how many chose hamsters, birds, or fish we first verified that the sum of all the percentages is 100% to check that the citizens answered just one time each one.
We have that 17+22+21+27+7+6 = 100.
Now hamsters, birds, or fish is an union of the people that answered this is a sum 6+21+17 = 44 in this case because the events are independients this means the intersection is empty. So the answer is 44.

The number of copies is 3,701 which has been sold to date.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
The book sold 39,800 copies in its first month of release.
Given that 9.3% of the number of copies sold to date.
To determine the number of copies has been sold to date.
⇒ 9.3% of 39,800 copies
⇒ (9.3/100) × 39,800
⇒ (0.093) × 39,800
⇒ 3,701.4
Round to the nearest whole number.
⇒ 3,701
Thus, the number of copies is 3,701 which has been sold to date.

Diamond spends a total of 45 minutes singing and She burns 5 calories per minute singing and 15 calories per minute dancing.Create an equation comparing the number of minutes Diamond spends singing (s) and the number of minutes she spends dancing (d) to the total number of calories she burns (C).Solve the equation to determine the total number of calories Diamond burns if she spends 20 minutes of her time singing.my teacher said base the on her spending 20 minutes singing
Answers
Answer:
475 calories.
Explanation:
The number of minutes Diamond spends singing = s
The number of minutes she spends dancing =d
Since she spends a total of 45 minutes singing
• s+d=45
Since she spends 20 minutes of her time singing.
• s=20 minutes
Substitution into: s+d=45
[tex]\begin{gathered} 20+d=45 \\ d=45-20=25 \end{gathered}[/tex][tex]\text{Rate}=\frac{Number\text{ of calories burned}}{Time}[/tex]The number of calories burned = Time X Rate
Therefore:
[tex]C=5s+15d[/tex]We then substitute s=20 minutes, d=25 minutes into C.
[tex]\begin{gathered} C=5s+15d \\ =5(20)+15(25) \\ =100+375 \\ =475 \end{gathered}[/tex]The total number of calories Diamond burns is 475 calories.

Where P is the principal, r is the rate as a decimal and t is the number of years.
So, replacing P = $4000, r = 5% = 0.05 and t = 3/4 years, we get:
