The value of a car decreases by 20 percent per year. Mr. Sing purchases a $22,000 automobile. What is the value of the car at the end of the second year?
$14,080
$17,600
$19,800
$26,400
Answer:
$14,080
Step-by-step explanation:
You can use a formula for exponential decay, but since it is only 2 years, you can find 80% of the original value, and then 80% of the new value.
Original value: $22,000
Value after 1 year: 80% of $22,000 = 0.8 * $22,000 = $17,600
Value after 1 year: $17,600
Value after 2 years: 80% of $17,600 = 0.8 * $17,600 = $14,080
Answer: $14,080
Answer:
it is A , 14,080

Answer:
We conclude that the slope of the line that is perpendicular to [tex]y=3x+6[/tex] will be: -1/3
Step-by-step explanation:
Given the equation
[tex]y=3x+6[/tex]
Comparing with the slope-intercept form
[tex]y=mx+b[/tex]
Here, m is the slope and b is the y-intercept.
so
[tex]y=3x+6[/tex]
Here the slope of line = m = 3
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
the slope of the perpendicular line will be: -1/3
Therefore, we conclude that the slope of the line that is perpendicular to [tex]y=3x+6[/tex] will be: -1/3

Answer:
6 +8√5
Step-by-step explanation:
The leg length can be reduced to simpler form:
3 +√45 = 3 +√(3²·5) = 3 +3√5
The perimeter is the sum of the side lengths, so is ...
(3 +3√5) +(3 +3√5) +(2√5) = 6 +8√5 . . . perimeter

Solve the equation. -18-6k = 6(1+ 3k) a) k= -2.67 b) k= -1 c) k = 1 d) k = 6
Answer: c) k = 1
Step-by-step explanation:
18 - 6k = 6 + 18k
18 = 6 + 12k
12 = 12k
1 = k
The value of k is -1.
Option B is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 7 is an equation.
We have,
-18 - 6k = 6 (1 + 3k)
Solve for k.
-18 - 6k = 6 (1 + 3k)
-18 - 6k = 6 + 18k
-18 - 6 = 18k + 6k
-24 = 24k
k = -24/24
k = -1
Thus,
k is -1.

find the slope of the graph write it as a fraction or whole number not a mixed number. find two points on the line (0,-4) and (3,0) slope = change in y / change in x
Answer:
The slope of the graph will be:
[tex]m=\frac{4}{3}[/tex]From the attached graph, it is clear that
the y-intercept is: (5, 0) ∵ to find the y-intercept, set x=0the x-intercept is: (0, -4) ∵ to find the x-intercept, set y=0Step-by-step explanation:
Given the two points on the line
(0, -4)(3, 0)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:-4\right),\:\left(x_2,\:y_2\right)=\left(3,\:0\right)[/tex]
[tex]m=\frac{0-\left(-4\right)}{3-0}[/tex]
[tex]m=\frac{4}{3}[/tex]
Hence, the slope of the graph will be:
[tex]m=\frac{4}{3}[/tex]
We can also find the equation of the line using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 4/3 and the point (0, -4)
[tex]y-\left(-4\right)=\frac{4}{3}\left(x-0\right)[/tex]
[tex]y+4=\frac{4}{3}\left(x-0\right)[/tex]
[tex]y+4=\frac{4}{3}x[/tex]
[tex]y=\frac{4}{3}x-4[/tex]
Therefore, the equation of the line will be:
[tex]y=\frac{4}{3}x-4[/tex]
The graph of the equation line is also attached below.
From the graph, it is clear that

Answer:r = -1
Step-by-step explanation:
8+8r-(3+3r)=0
We add all the numbers together, and all the variables
8r-(3r+3)+8=0
We get rid of parentheses
8r-3r-3+8=0
We add all the numbers together, and all the variables
5r+5=0
We move all terms containing r to the left, all other terms to the right
5r=-5

A softball pitcher throws a softball to a catcher behind home plate. The softball is 3 feet above the ground when it leaves the pitcher’s hand at a velocity of 50 feet per second. If the softball’s acceleration is –16 ft/s2, which quadratic equation models the situation correctly?
h(t) = at2 + vt + h0
a) h(t) = 50t2 – 16t + 3
b) h(t) = –16t2 + 50t + 3
c) 3 = –16t2 + 50t + h0
d) 3 = 50t2 – 16t + h0
9514 1404 393
Answer:
b) h(t) = –16t^2 + 50t + 3
Step-by-step explanation:
If you put the given values in the given equation, you get ...
h(t) = at^2 + vt + h0
where a = -16, v = 50, h0 = 3
h(t) = -16t^2 +50t +3 . . . . . matches choice B

The given equation models the vertical height based on a vertical velocity of 'v'. It does not apply in the case where the horizontal velocity is v = 50 ft/s. None of the answer choices correctly models the situation where the pitcher is throwing toward the catcher.

Diego says, “113. If I put 1 rhombus on a trapezoid, the leftover shape is a triangle, which is 13 of the trapezoid.”
Jada says, “I think it’s 112. Since we want to find out ‘how many rhombuses,’ we should compare the leftover triangle to a rhombus. A triangle is 12 of a rhombus.”
Is the answer 113 or 112?
