Tan 2° = x / 1 mile,   where x is the vertical change
0.03492 = x / 1 mile
x = 1 mile · 0.03429 = 0.03492 miles
1 mile = 5,280 feet
0.03492 · 5,280 = 184.38 ft
Answer: The vertical change is 184.38 feet

Vikentia [17]

The recursive definition for the amount of the blood pressure medicine in hareem bloodstream after n hours would be a_1=25, a_n = 0.60_{n-1} +25

Hence, option B is correct.

<h3>What is the recursive rule?</h3>

A rule is defined such that its definition includes itself.

Example:

F(x) = F(x-1) + c

is one such recursive rule.

Hareem takes medicine to control his blood pressure.

he takes a 25 mg pill in the morning.

Suppose that 60% of the medicine is processed by hareem's body by the time he takes a second 25 mg pill in the evening.

So, the recursive definition for the amount of the blood pressure medicine in hareem bloodstream after n hours would be;

a_1=25, a_n = 0.60_{n-1} +25

Hence, option B is correct.

How do i answer this question?
blondinia [14]

Answer:

f^{-1} (59) = 20

Step-by-step explanation:

f^{-1} (x) is the inverse of f(x)

to find the inverse function, let f(x) = y and rearrange to make x the subject.

y = 3x - 1 ( add 1 to both sides )

y + 1 = 3x ( divide both sides by 3 )

\frac{y+1}{3} = x

change y back into terms of x with x = f^{-1} (x) , then

f^{-1} (x) = \frac{x+1}{3} , then

f^{-1} (59) = \frac{59+1}{3} = \frac{60}{3} = 20

Tju [1.3M]
How I would solve this is but it in a calculator. But if you can't chance 1/4 to a decimal. So it's .25 Then multiply 36x.25=9.

Which of the following equations have no solution? Check all that apply.
timurjin [86]

Answer:

C

Step-by-step explanation:

4(3 - x) =2(6 - 2x)

(4x3) + (4x(-x))=(2x6) + (2x(-2x))

12 + (-4x) = 12 + (-4x)

12 - 4x = 12 - 4x

collect like terms

12 - 12 = -4x + 4x

0 = 0
