On the ceiling of a cavern, a stalactite grows downward

1 answer:

4 0

The stalactites become 0.004 + 0.006 = 0.01 inches closer each year, and begin 10 feet apart, or 120 inches apart.

let y be the distance between them, and x be the number of years that go by:
y = -0.01x + 120

We want to find where y = 0, where they meet:
0 = -0.01x + 120 Add 0.01x to both sides
0.01x = 120 Multiply both sides by 100
x = 12,000

The stalagmite and stalactite will meet in 12,000 years

You just reflected on working with right triangles and trigonometric concepts. How important were concepts that you learned prev

Idk if ya still need it or if this will help but this is what i put for mine

Concepts that I had previously learned about are quite important because math goes hand and hand. if you try to skip something and go ahead you'll most likely get confused because there could of been something highly important to that would help you understand whats ahead. in the previous unit it tells you about triangles and their description like a right triangle-90 degree angle and where legs and hypotenuse is located, this unit has had a ton about right triangles.

Gang charges $22.50 per hour for Consulting Services how much was she charged for seven and a half hours of Consulting

Bogdan [553]

Answer

$168.75

Step-by-step explanation:

$22.50 per hour meaning every hour she gets 22.50

half an hour would be half the money so

22.50 * 7 = 157.50

22.50/2 = 11.25

157.50 + 11.25 = 168.75

168.75 is the answer

For tax purposes, a car rental company assumes each car in their fleet depreciates by 6% per year. If the initial value of a car

n200080 [17]

The value of a car after 10 years be $20898.27 if the car rental company assumes each car in their fleet depreciates by 6% per year option (a) $20898.27 is correct.

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent $\rm y = a^x$

where a is a constant and a>1

We can solve this problem by exponential function:

The word depreciate means the price is decreasing.

We can find the value be when the car is 10 years old:

p = 38800(1 - 0.06)¹⁰

p = 38800(0.94)¹⁰

p = 20898.266 ≈ $20898.27

Thus, the value of a car after 10 years be $20898.27 if the car rental company assumes each car in their fleet depreciates by 6% per year option (a) $20898.27 is correct.

Use a normal approximation to find the probability of the indicated number of voters. In this case assume that 150 eligible vote

alexdok [17]

The number of people who voted follows a binomial distribution with probability of having voted $p=0.22$ and $n=150$ subjects, which means the approximating normal distribution should have mean $np=33$ and standard deviation $\sqrt{np(1-p)}\approx5.07$ .

With the continuity correction, you have

$\mathbb P(X$
