Answer:

The actual change in the car's value is $[tex]1700[/tex] and the relative change is [tex]7.20[/tex]%.

Step-by-step explanation:

It is given that the value of a car is dropped from $[tex]23600[/tex] to $[tex]21900[/tex].

So, the change in the value is the drop in the value of car, which is, [tex]23600-21900=1700[/tex].

So, the actual change in this car's value is $[tex]1700[/tex].

The relative change can be given by the expression,

[tex]\dfrac{\:\rm{Actual Change}}{\:\rm{Original Value}}\times100[/tex]

Substituting values, the relative change can be given by,

[tex]\begin{aligned}\dfrac{1700}{23600} \times 100&=\dfrac{1700}{236}\\&=7.20\end{aligned}[/tex]

Step-by-step explanation:

Since the the two angles are complementary, then

[tex](3x + 2) + (5x - 14) = 90[/tex]

or

[tex]8x - 12 = 90 \Rightarrow 8x = 102[/tex]

[tex]x = 12.75[/tex]

so

[tex]\angle{YXZ} = 5(12.75) - 14 = 49.75°[/tex]

Answer:

{-9,-8,-7,-6,-5}

Step-by-step explanation:

Set C is negative Integers greater than -10

{-9, -8, -7, -6, -5, -4, -3, -2, -1}

Elements less than or equal to -5

{-9, -8, -7, -6, -5}

Step-by-step explanation:

the rate of change (like the slope for a line) is expressed by y/x.

for x = -1 we get y = -3

for x = 3 we get y = 5

so, while x changes by 4 units (-1 to +3), y changes by 8 units (-3 to +5).

so, the average change rate in that interval is 8/4 = 2/1 = 2

Answer:

25×4

Step-by-step explanation:

Answer:

(-1;3)

(3 - 5)/2 = -1

(-2 + 8)/2 =3

Midpoint of segment (3, -2) and (-5, 8) is (-1, 3).

The midpoint formula allows us to find the point that lies exactly halfway between two given points on a line segment. For two points represented as (x₁, y₁) and (x₂, y₂), the midpoint ([tex]x_m[/tex], [tex]y_m[/tex]) is calculated using the formula:

[tex]x_m[/tex] = (x₁ + x₂) / 2

[tex]y_m[/tex] = (y₁ + y₂) / 2

Now, let's apply this formula to find the midpoint of the segment with endpoints (3, -2) and (-5, 8):

x₁ = 3, y₁ = -2

x₂ = -5, y₂ = 8

[tex]x_m[/tex] = (3 + (-5)) / 2 = (-2) / 2 = -1

[tex]y_m[/tex] = (-2 + 8) / 2 = 6 / 2 = 3

So, the midpoint of the segment is (-1, 3).

In this explanation, we used the midpoint formula, represented by the subscript "m," to find the midpoint ([tex]x_m[/tex], [tex]y_m[/tex]) of the segment with endpoints (x₁, y₁) and (x₂, y₂). By substituting the given coordinates into the formula, we computed the x-coordinate and y-coordinate separately. The midpoint gives the exact center of the segment, dividing it into two equal parts. In this case, the midpoint lies at (-1, 3), which is indeed the point that is equidistant from both (3, -2) and (-5, 8) on the line segment.

Step-by-step explanation:

f(x) = x + 1

g(x) = -3x

h(x) = 5-x

find fogoh

first we find fog

f(g(x)) = -3x + 1

then we find fogoh = -3(5-x ) +1

= -15 + 3x +1

Answer:

5 packs of erasers

Step-by-step explanation:

To solve this problem, find the least common multiple. The least common multiple is the smallest number that both terms are a factor of. In this case, that number is 30. Both 10 and 6 are a factor of 30. So, the answer is the other factor needed to get 30 through multiplication. 10's other factor is 3 and 6's other factor is 5. Therefore, the answers are 3 and 5 respectively.

The sidewalk between library and humanities

This is represented with (a).

The value of (a) will be calculated using Pythagoras theorem.

So, we have:

[tex]a^2 = 15^2 + 15^2[/tex]

[tex]a^2 = 450[/tex]

Take square roots

[tex]a = 21.21[/tex]

Sidewalk between chemistry and library

This is represented with (d).

First calculate the value of (b) and (c)

[tex]c + 15 = 30[/tex]

So:

[tex]c = 15[/tex]

Also:

[tex]b + 15 = 40[/tex]

So:

[tex]b = 25[/tex]

The value of (d) will be calculated using Pythagoras theorem.

[tex]d^2 = b^2 + c^2[/tex]

[tex]d^2 = 25^2 + 15^2[/tex]

[tex]d^2 = 850[/tex]

Take square roots

[tex]d = 29.15[/tex]

The sidewalk between chemistry and humanities

This is represented with (e).

The value of (e) will be calculated using Pythagoras theorem.

Evaluate this the way you would any function. Start with the inner parentheses according to the order of operations. Substitute for the function variable and do the arithmetic.

  g(f(4)) = g(-4·4 +10) = g(-6) = (-6)² +7(-6) +5 = 36 -42 +5
