Answer:

1/2

Step-by-step explanation:

Given:

Price of a new car = 25000

Depreciation rate = 8.25% = 0.0825

Time = 15 years.

To find:

The value of the car after 15 years.

Solution:

The exponential decay model is

[tex]y=a(1-r)^t[/tex]

Where, a is the initial value, r is the rate of decay and t is number of years.

Putting a=25000, r=0.0825 and t=15 in the above formula.

[tex]y=25000(1-0.0825)^{15}[/tex]

[tex]y=25000(0.9175)^{15}[/tex]

[tex]y=25000(0.274847)[/tex]

[tex]y=6871.175[/tex]

Therefore, the value of the car after 15 years will be 6871.175.

Answer:

[tex]\frac{121}{16}[/tex]

Step-by-step explanation:

[tex](-2\frac{3}{4})^2\\= (-\frac{4\times2+3}{4})^2\\=(-\frac{11}{4})^2\\=\frac{121}{16}[/tex]

Answer:

its the first one

Step-by-step explanation:

our  vertex is (-2,0)

so replace it in the equation y ≤ (x + 2)^2

so, 0 ≤ (-2 + 2)^2

= 0 ≤ (-4)^2

= 0 ≤ 16

look at that statement, is 0 less than or equal to 16? Yes. Therefore it is correct, so you shade out side of the parabola.

TIP: If the parabola opens up and:

        y <, then shade outside.

        y >, then shade inside.

Do the opposite if the parabola opens down.

Step-by-step explanation:

✧ [tex] \underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \: O \: N}}}} : [/tex]

~Set up an equation and solve for x :

→ [tex] \large{ \tt{10x + 45 \degree = 75 \degree + 70 \degree}}[/tex] [ Exterior angle is always equal to the sum of two non-adjacent interior angles ]

Add the numbers : 75° & 70°

→ [tex] \large{ \tt{10x + 45 \degree = 145 \degree}}[/tex]

Since we want to get rid of the constant in the left hand side , subtract 45 from both sides :

→ [tex] \large{ \tt{10x + 45 \degree - 45 \degree= 145 \degree - 45 \degree}}[/tex]

→ [tex] \large{ \tt{10x \: \cancel{ + 45 \degree} \: \cancel{ - 45 \degree} = 100 \degree}}[/tex]

→ [tex] \large{ \tt{10x = 100 \degree}}[/tex]

~Divide both sides by 10

→ [tex] \large{ \tt{ \frac{10x}{10} = \frac{100}{10}}} \degree[/tex]

→ [tex] \large{ \tt{x = 10 \degree}}[/tex]

Answer:

We should use the following transformation: [tex](x', y') = (x+2, y + 4)[/tex] (Translation of circle A to the center of the circle B)

Step-by-step explanation:

We should apply a translation prior to determine if both circles are similar. If we translate the circle A to the center of the circle B. The translation needed is the vectorial distance between both centers:

[tex]T(x,y) = B(x,y)-A(x,y)[/tex] (1)

Where:

[tex]T(x,y)[/tex] - Translation vector.

[tex]A(x,y)[/tex] - Location of the center of the circle A.

[tex]B(x,y)[/tex] - Location of the center of the circle B.

If we know that [tex]A(x,y) = (-5,-6)[/tex] and [tex]B(x,y) = (-3,-2)[/tex], then the translation vector is:

[tex]T(x,y) = (-3,-2)-(-5,-6)[/tex]

[tex]T(x,y) = (2,4)[/tex]

We should use the following transformation: [tex](x', y') = (x+2, y + 4)[/tex] (Translation of circle A to the center of the circle B)

Answer:

x = 6

Step-by-step explanation:

9x - 11 + 57 + 80 = 180

9x + 126 = 180

9x = 54

x = 6

Answer:

30

Step-by-step explanation:

I am sure

If correct which it is, can you please mark brainliest

Angle three would also be thirty, and the other two angles (2+4) would be 180 (the degrees in a straight line ALWAYS) minus 30, which would be 150. The answer your looking for would be 30 though.

Answer:

54 ft

Step-by-step explanation:

1/4=3 ft, if you convert the measurements to feet, it adds up to 54

Answer:

Answer:

[tex]y = 2(0.5) {}^{x} [/tex]

Step-by-step explanation:

Use the general formula of exponential equation

[tex]y = ab {}^{x} [/tex]

Plug 0,2 into the function

[tex] - 2 = ab {}^{0} [/tex]

[tex] - 2 = a \times 1[/tex]

[tex]a = - 2[/tex]

[tex]y = - 2b {}^{x} [/tex]

[tex] - 4 = - 2b {}^{ - 1} [/tex]

[tex]2 = b {}^{ - 1} [/tex]

[tex] {2}^{ \frac{ 1}{ - 1} } [/tex]

[tex]2 {}^{ - 1} = 0.5[/tex]

B=0.5

[tex]y = 2(0.5) {}^{x} [/tex]
