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.

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: 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

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°

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 ...

Answer:

B

Step-by-step explanation:

The required expression is given by C=0.75d which shows the Total cost of D donuts in dollars. Option B is correct.

Given that,

A grocery store charges $0.75 per donut. Which equation can be used to find c, the total cost, in dollars, to buy d donuts is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
According to the question,
Cost of a donut = 0.75
Cost of d donut = 0.75 d
C = 0.75d

Thus, the required expression is given by C=0.75d which shows the Total cost of D donuts in dollars. Option B is correct.

Answer: [tex]\sin x+6[/tex]

[tex]-\cos x+6x+5-3\pi[/tex]

Step-by-step explanation:

Given

[tex]f''(x)=\cos x[/tex]

Integrating the equation

[tex]\Rightarrow f''(x)=\dfrac{d^2y}{dx^2}=\cos x\\\\\Rightarrow \int \frac{\mathrm{d^2} y}{\mathrm{d} x^2}=\int \cos x\\\\\Rightarrow \frac{\mathrm{d} y}{\mathrm{d} x}=\sin x+c[/tex]

Put [tex]x=\frac{\pi}{2}\ \text{and}\ \frac{dy}{dx}=7[/tex]

[tex]\Rightarrow 7=\sin \frac{\pi }{2}+c\\\Rightarrow c=7-1\\\Rightarrow c=6[/tex]

[tex]\Rightarrow \dfrac{dy}{dx}=\sin x+6[/tex]

again integrating both sides of the equation

[tex]\Rightarrow \int \frac{\mathrm{d} y}{\mathrm{d} x}=\int (\sin x+6)dx\\\\\Rightarrow y=-\cos x+6x+c_1[/tex]

Put  [tex]x=\frac{\pi}{2}\ \text{and}\ y=5[/tex]

[tex]\Rightarrow 5=-\cos \frac{\pi}{2}+6(\frac{\pi}{2})+c_1\\\Rightarrow c_1=5-3\pi[/tex]

[tex]\therefore f(x)=y=-\cos x+6x+5-3\pi[/tex]

Answer:

Step-by-step explanation:

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:

Domain

R (all real numbers)

Range

{h element R : h<=41}

Derivative:

d/dt(-t^2 + 12 t + 5) = -2 (t - 6)

Indefinite integral assuming all variables are real:

integral(-t^2 + 12 t + 5) dt = -t^3/3 + 6 t^2 + 5 t + constant

Global maximum:

max{-t^2 + 12 t + 5} = 41 at t = 6
