Spring Airlines Flight 123 is currently flying at a height of 45,000 feet and will descend at a rate of 700 feet per minute. At the same time, Summer Airlines Flight 789 is taking off from ground level and will ascend at a rate of 1,200 feet per minute. Which equation can be used to find m, the number of minutes it will take for the two planes to be at the same height?

Answers

Answer 1

Answer:

23.68421052632 minutes

Step-by-step explanation:

Given that :

Spring airlines :

Current height = 45,000

Rate of descent = 700 ft per minute ; represent descent rate as negative

Summer airlines :

Current position = ground level = 0

Rate of ascent = 1200 ft per minute

Number of minute it will. Take for the 2 planes to be at the same height :

Height * descent rate = height * ascent rate

45000 + (-700)m = 0 + 1200m

45000 - 700m = 0 + 1200m

-700m - 1200m = 0 - 45000

-1900m = - 45000

m = 45000 / 1900

m = 23.68421052632 minutes

Hence the two planes will be at the same height after 23.68421052632 minutes

Alex was put on an improvement at work and they lowers his pay by 3% an hour before his decrease in pay he was making $14 an hour how much money is Alex making an hour afther his decrease in pay

Answers

Answer: Alex is making $ 13.58 after his decrease in pay.

Step-by-step explanation:

Given: Hourly pay for Alex before decrease in pay = $14

His salary decreased by 3%.

New hourly pay = Previous hourly pay - 3% of ( Previous hourly pay )

= $(14-0.03 (14))

= $ (14(1-0.03))

= $ (14(0.97))

=$ 13.58

Hence, Alex is making $ 13.58 after his decrease in pay.

A polynomial function has a degree 4, a negative leading coefficient, and real zeros 3 with multiplicity 2, -2 with a multiplicity of 1, and -3 with a multiplicity of 1

Answers

Answer: p(x) = -n*(x - 3)^2*(x + 2)*(x + 3)

Step-by-step explanation:

For a polynomial whit roots a, b, c, d, e, ... (Where those numbers are not necessarly different)

We can write a polynomial with those roots as:

A*(x -a)*(x - b)*(x - c)*....

Where A is a real number, and it's the leading coefficient (The coefficient that multiplies the highest power term)

In this case we have the roots:

3, 3, -2 and -3 (3 is two times, because it has a multiplicity of 2)

Then this polynomial can be written as:

A*(x - 3)*(x - 3)*(x + 2)*(x + 3)

And we know that the leading coefficient is negative, then we can write:

A = -n, where n > 0.

Then our polynomial is:

p(x) = -n*(x - 3)^2*(x + 2)*(x + 3)

Answer:

-25.

Step-by-step explanation:

What is the difference of outputs for any two inputs that are one value apart?

If you look at the column of "x" [input], you will see that they are 1 unit apart. You can thus look at the corresponding values of "f(x)" [output] and determine their difference. Checking all of those, gives us the difference (same for all).

AWARDING DOUBLE POINTS question in pic, will report anything other than the answer

Answer:

m∠R is 72°

Step-by-step explanation:

In the given figure

∵ ΔPQR ≅ ΔUVW

→ From congruency

∵ m∠P = m∠U

∵ m∠Q = m∠V

m∠R = m∠W

∵ m∠R = (10x - 18)°

∵ m∠W = 8x°

∵ m∠R = m∠W

→ Equate their measures

10x - 18 = 8x

→ Add 18 to both sides

∵ 10x - 18 + 18 = 8x + 18

∴ 10x = 8x + 18

→ Subtract 8x from both sides

∴ 10x - 8x = 8x - 8x + 18

∴ 2x = 18

→ Divide both sides by 2 to find x

x = 9

→ Substitute the value of x in the m∠R

∵ m∠R = 10(9) - 18

∴ m∠R = 90 - 18

∴ m∠R = 72°

m∠R is 72°
