2nd question can a professional help me out please.
solong [7]

Answer:

It is a right triangle.

Step-by-step explanation:

The m < QSP = 90 degrees because the other 2 angles in triangle PQS are 45 degrees so m < QSP = 180 - 2(45) = 90 degrees.

Therefore triangle PQS is a right triangle.

If s(x) = 2 – x2 and t(x) = 3x, which value is equivalent to (s0t)(-7)?
Juliette [100K]

Answer:

The answer would be -439

Step-by-step explanation:

To find this, start by finding t(-7)

t(x) = 3x

t(-7) = 3(-7)

t(-7) = -21

Now that we have this answer, we input it into the s(x) equation.

s(x) = 2 - x^2

s(-21) = 2 - (-21)^2

s(-21) = 2 - 441

s(-21) = -439

P = 14.7e-0.21x, where x is the number of miles above sea level. To the nearest foot, how high
AlladinOne [14]

9514 1404 393

Answer:

  13064 feet

Step-by-step explanation:

We can rewrite the formula so that x is in feet. Equating the new formula to 8.743 PSI, we have ...

  8.743 = 14.7e^(-0.21x/5280)

Dividing by 14.7 and taking natural logs, we have ...

  ln(8.743/14.7) = -0.21x/5280

Multiplying by the inverse of the coefficient of x gives ...

  x = 5280·ln(8.743/14.7)/-0.21 ≈ 13064.0806

The peak of the mountain is about 13,064 feet high.
