A car with a cost of $25,000 is decreasing in value at a rate of 10% each year. The function g(t)= 25,000(0.9)^t gives the value of the car after t years. When will the value of the car be about $12,000? A) after 7 years B) after 9 years C) after 13 years Could you also explain how to do it?

Answers

12,000 = 25,000 $(0.9)^(t)$
Divide both sides by 25,000 → 0.48 = $(0.9)^(t)$
Convert to log form → $log_(0.9)$ 0.48 = t
Use the change of base formula → $(log 0.48)/(log 0.9)$ = t
Plug into the calculator → 6.966 = t

The equation of a hyperbola is shown. (x-3)^2/81-y^2/144=1
What are the coordinate of the center of the hyperbola?
A.) (3,0)
B.) (0,-30)
C.) (0,3)
D.) (-3,0)

Answers

for equatin (x-h)^2/a^2 - (y-k)^2/b^2 =1 center will be (h,k)
in our problem h=3, k= 0
so center is (3,0)

Find the distance and midpoint for the following coordinates.
P(7.6 , 10.1) and Q(4.6 , 3.1)

Answers

Solving for the midpoint:

x - coordinate: (7.6 + 4.6)/2 = 6.1
y - coordinate: (10.1 + 3.1)/2 = 6.6

Midpoint: (6.1 , 6.6)

Solving for the distance:

Distance formula: sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

D = sqrt( (7.6 - 4.6)^2 + (10.1 - 3.1)^2 )
D = sqrt( 3^2 + 7^2)
D = sqrt(58)
D = 7.62 units

Distance = 7.62 units

Kyla measured the weight of a bunch of bananas as 1,100 grams using the scale.What is the margin of error?

A. 1,000 g to 1,200 g

B. 1,050 g to 1,150 g

C. 1,150 g to 1,200 g

D. 1,000 g to 2,000 g

Answers

Answer:

B. 1,050 g to 1,150 g

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Before we can find an answer for this question we should know what a margin of error is.

Margin of Error is the minimum amount of error allowed in a specific measurement. This exists because of the miscalculations that can happen.

Knowing the information above we can confidently say that the answer is B. 1,050 g to 1,150 g . This gives us a padding of error of 50 over and under the actual value of 1,100 grams

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

B, because thats 50 grams either direction of the given weight.
