$36000. For every year after it is purchased, the car loses 17% of its value due to depreciation. What is the value of the car after 64 months? find in exponential function grade 11 math
Answer:
$13,320Step-by-step explanation:
The expression for depreciation is
V=C(1-r)^t ,
where V is the value of the car after t years,
C is the original cost, and
r the rate of depreciation. If a car
given
C=$36000
r=17%= 0.17
t in years 64/12= 5.33years
Substituting to the formula we have
V=36000(1-0.17)^5.33
V=36000(0.83)^5.33
V=36000*0.370
V=13,320
the value will be $13,320
Simplify: square root of y^10
Answer: the second option |y^5|
Step-by-step explanation:
The values of the expression [tex]\sqrt{y^{10}}[/tex] is [tex]|y^5|[/tex].
Option B is the correct answer.
We have,
Expression:
[tex]\sqrt{y^{10}}[/tex]
This can be written as,
Simplifying the powers.
[tex]\sqrt{y^{2 \times 5}}[/tex]
Square root can be written as,

A quadratic equation can be written in vertex form or i n standard form. Sometimes one form is more beneficial than the other. Identify which form would be more helpful if you needed to do each task listed below and explain why.
a. Factor the equation.
b. Graph the parabola.
c. Identify the vertex, minimum, or maximum of the parabola.
d. Solve the equation using the quadratic formula
Answer:
a. Standard form
b. Vertex form
c. Vertex form
d. Standard form
Step-by-step explanation:
The vertex form of a quadratic equation is y = a·(x - h)² + k
The standard form of a quadratic equation is y = a·x² + b·x + c
Therefore;
a. In order to factor the equation, the vertex form needs to be expanded to the standard form first, to obtain the factors of the equation
b. The parabola is easily graphed with the information on the vertex given in the vertex form of the quadratic equation
c. The vertex, minimum or maximum of the parabola are easily obtained in the vertex form of the quadratic equation
d. The quadratic formula is defined based on the standard form of the quadratic equation
The forms of a quadratic equation are the ways the equation can be written.
The tasks and the required forms are:
Factor the equation - Standard formGraph the parabola - Vertex formIdentify the vertex, minimum or maximum - Vertex formQuadratic formula - Standard formThe standard form of a quadratic equation is:
[tex]\mathbf{y =ax^2 + bx + c}[/tex]
The above form can be used to calculate the roots of a quadratic equation, using the following quadratic formula
[tex]\mathbf{x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}}[/tex]
Also, a quadratic equation can be easily factorized from [tex]\mathbf{y =ax^2 + bx + c}[/tex]
This means that, the standard form can be used for (a) and (d)
The vertex form of a quadratic equation is:
[tex]\mathbf{y = a(x - h)^2 + k}[/tex]
The above form is used to
Identify the vertexIdentify the maximum and the minimum points of a parabolaThis means that, the vertex form can be used for (b) and (c)

Select the true statement. Dilations of an angle must be congruent to the original angle. Dilations of a triangle must be congruent to the original triangle Dilations of a segment must be congruent to the original segment. Dilations of a circle must be congruent to the original circle.
Answer:
The true statements is;
Dilations of an angle must be congruent to the original angle
Step-by-step explanation:
Given that an angle is formed by the intersection of two rays, and that the ratio of the sides of a figure, before and after a dilation are the same, for an angle in a triangle we have, by sine rule;
a/(sin(α)) = b/(sin(β)) = c/(sin(γ))
Rearranging, gives;
a/b = (sin(α))/(sin(β))
Whereby for the dilation, we have;
a'/b' = (sin(α'))/(sin(β'))
We have;
a/b = a'/b'
∴ (sin(α))/(sin(β)) = (sin(α'))/(sin(β'))
Similarly, we have;
(sin(β))/(sin(γ)) = (sin(β'))/(sin(γ'))
(sin(α))/(sin(γ)) = (sin(α'))/(sin(γ'))
Given that α, β, and γ, are less than 180°, we have
α = α'
∴ α ≅ α' by definition of congruency
β = β'
β ≅ β' by definition of congruency
γ = γ'
γ ≅ γ' by definition of congruency
Therefore; dilations of an angle must be congruent to original angle

How many solutions does 3x+15=3 (x+5)
Answer:
0=0
Step-by-step explanation:
3x- 15=3 (x- 5)
We simplify the equation to the form, which is simple to understand
3x-15=3(x-5)
Reorder the terms in parentheses
3x-15=+(+3x-15)
Remove unnecessary parentheses
+3x-15=+3x-15
We move all terms containing x to the left and all other terms to the right.
+3x-3x=-15+15
We simplify left and right side of the equation.
0x=0
0=0
This equation is an identity, so all real numbers are solutions.

A pitcher in a major league baseball game threw 100 pitches. If 36 of the pitches were balls and 64 were strikes, what is the ratio of balls to strikes for that game?
Answer:
The ratio of balls to strikes is 9 : 16
Step-by-step explanation:
From the question, a pitcher in a baseball game threw a total of 100 pitches in which some were balls and others were strikes. 36 of them were balls and 64 were strikes.
To determine the ratio of balls to strikes for the game, we will divide the number of balls by the number of strikes.
That is,
Ratio of balls to strikes = Number of balls / Number of strikes
Number of balls = 36
Number of strikes = 64
Therefore,
Ratio of balls to strikes = 36 / 64
Ratio of balls to strikes = 9 / 16
Hence, the ratio of balls to strikes is 9 : 16.

How many integers between 299 and 501 are divisible by both 2 and 5
Answer:
21
Step-by-step explanation:
The question has to do with multiples.
The count of numbers between 299 and 501 is two hundred and two (202).
Step 1: Find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.
Multiples of 2:
2, 4, 6, 8, 10, 12, 14
Multiples of 5:
5, 10, 15, 20
Therefore,
LCM(2, 5) = 10
The number of integers between 299 and 501 that are divisible by both 2 and 5 is any number that can be divided by 10.
Therefore the number of integers between 299 and 501 that are divisible by both 2 and 5 is 21.
