The following equation 0.85 P₀ = P₀ [tex]\rm e^{-0.00012h}[/tex] will find the height at which air pressure is 85% of the air pressure at sea level

The pressure exerted by air is called atmospheric pressure.

It is given that

P(h)=P₀ [tex]\rm e^{-0.00012h}[/tex]

Air pressure: P(h)

Height above the surface of the Earth (in meters): h

Air pressure at the sea level: P₀

Height at which air pressure is 85% of the air pressure at sea level:

h=?

P(h)=85% P₀

P(h)=(85/100) P₀

P(h)=0.85 P₀

Replacing P(h) by 0.85 P₀ in the formula above:

P(h)=P₀ [tex]\rm e^{-0.00012h}[/tex]

0.85 P₀ = P₀ [tex]\rm e^{-0.00012h}[/tex]

Therefore Option A is the correct answer.

nate form assuming t is real:

h(t) + (t - 12) t = 5

Alternate forms:

h(t) = 5 - (t - 12) t

h(t) + t^2 = 12 t + 5

Roots:

t = 6 - sqrt(41)

t = 6 + sqrt(41)

Properties as a real function:

Answer:

A cone

Step-by-step explanation:

The diagram that shows the rotation of the triangle is not shown, but the question can still be solved.

The rotation of a triangle will form a cone; in fact a cone is referred to as a rotated triangle.

When rotated, the base of the triangle will form the circular base of the cone; the slant lengths of the triangle will form the slant length of the triangle.

The height of both shapes will remain the same.

Answer:

X=131°

Step-by-step explanation:

y= 101°

z= 52°

X= ?

BCD is a ∆

therefore y= Z + BCD angle (exterior angle of a ∆ is equal to the sum of opposite interior Angles)

angle BCD= y-z

= 101°-52°

=49°

also X= 180°- angle BCD (sum of angles on a straight line)

X= 180°-49°

X= 131°

Answer:

x = 131°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

y is an exterior angle of the triangle, then

∠ DCB + z = y , that is

∠ DCB + 52 = 101 ( subtract 52 from both sides )

∠ DCB = 49°

∠ DCB and x are adjacent angles and sum to 180°

∠ DCB + x = 180

49° + x = 180° ( subtract 49° from both sides )

x = 131°

==========================================================

Explanation:

We replace every copy of x with -2. From there, use PEMDAS to simplify

y = 3x^2 + 17

y = 3(-2)^2 + 17

y = 3(4) + 17

y = 12 + 17

y = 29

Therefore, x = -2 pairs up with y = 29.

Put another way, the point (x,y) = (-2, 29) is on the function curve.

Answer:

  D.  2%  

Step-by-step explanation:

The growth rate can be found by looking at the growth factor of the exponential function.

  f(x) = (initial value) × (growth factor)^x

The growth rate is related by ...

  growth factor = growth rate + 1

This means the growth rate of f(x) is 1.04 -1 = 0.04 = 4%.

__

We can write the function g(x) describing the table as ...

  g(x) = (value at x=x1) × ((value at x=x2)/(value at x=x1))^((x-x1)/(x2-x1))

So, this could be ...

  g(x) = 31.21 × (32.47/31.21)^((x-2)/2) = a·b^x

     where b = (32.47/31.21)^(1/2) ≈ 1.02 . . . . growth factor

This means the growth rate for g(x) is 1.02 -1 = 0.02 = 2%.

__

Then the difference between the growth rates of the two functions is ...

  4% - 2% = 2% . . . . . matches choice D

Answer: 6.6 miles

Step-by-step explanation:

Since he finished 22% of his skiing in the morning, that means he still has 78% (100% - 22%) of his skiing left.

The remaining 78% is equivalent to 23.4 miles. We need to know the total miles of the skiing. This will be:

78% of x = 23.4

0.78 × x = 23.4

0.78x = 23.4

x = 23.4 / 0.78

x = 30 miles

Since the total skiing is 30 miles and he has 23.4 miles left, the miles covered in the morning will be:

= 30 - 23.4

= 6.6 miles
