The atmospheric pressure on an object decreases as altitude increases. If a is the height (in km) above sea level, then the pres

seraphim [82]

Answer:

373.8mmHg

Step-by-step explanation:

a =height (in km) above sea level,

the pressure P(a) (in mmHg) is approximated given as

P(a) = 760e–0.13a .

To determine the atmospheric pressure at 5.458 km, then we will input into the equation

P(5.458km) = 760e–0.13a .

= 760e^(-0.13×5.458)

=760e^-(0.70954)

= 760×0.4919

=373.8mmHg

Therefore, the atmospheric pressure at 5.458 km is 373.8mmHg

Determine the measure of ∠Q, rounded to the nearest tenth of a degree. images attached.

const2013 [10]

Answer:

Step-by-step explanation:

Using the Sine rule in Δ QRS , that is

$\frac{q}{sinQ}$ = $\frac{r}{sinR}$ , that is

$\frac{15}{sinQ}$ = $\frac{12}{sin50.1}$ ( cross- multiply )

12× sinQ = 15 × sin50.1° ( divide both sides by 12 )

sinQ = $\frac{15sin50.1}{12}$ , thus

Q = $sin^{-1}$ ( $\frac{15sin50.1}{12}$ ) ≈ 73.5° ( to the nearest tenth )

What are the coordinates of P' if P (-5,-4) undergoes a dilation, centered at the origin, with a scale factor of K=2?

Margaret [11]

Answer:

$P' = (-10,-8)$

Step-by-step explanation:

Given

$P = (-5,-4)$

$k =2$

Required

Determine the image P'

P' is calculated by multiplying P and k.

i.e.

$P' = P * k$

This gives:

$P' = (-5,-4) * 2$

$P' = (-5* 2,-4* 2)$

$P' = (-10,-8)$

Hence, the image P' after dilating P is (-10,-8)
