Name the reference angle in both degrees and radians.

Answers

Answer 1

Answer:

[tex]\mathbf{\theta = 0.0875 \ radians}[/tex]

Step-by-step explanation:

Given that:

The distance between city A and city B = 350 miles; &

The radius of the earth = 4000 miles

We all know that:

l = rθ

[tex]\theta = \dfrac{l}{r}[/tex]

[tex]\theta = \dfrac{350}{4000}[/tex]

[tex]\mathbf{\theta = 0.0875 \ radians}[/tex]

From l = rθ; recall that l = a

so;

a = rθ

350 = 4000×θ

θ = 350/4000

θ = 35/400 degree

In radians;

θ = (35/400) × (π/180)

θ = (7π /800× 180) radians

The population of a certain species of insect is given by a differentiable function P, where P(t) is the number of insects in the population, in millions, at time t, where t is measured in days. When the environmental conditions are right, the population increases with respect to time at a rate that is directly proportional to the population. Starting August 15, the conditions were favorable and the population began increasing. On August 20, five days later, there were an estimated 10 million insects and the population was increasing at a rate of 2 million insects per day. Which of the following is a differential equation that models this situation?

a. P=2(t−5)+10
b. dP/dt=2/5t
c. dP/dt=1/5P
d. dP/dt=5P

Answers

Answer:

c. dP/dt = (1/5)P

Step-by-step explanation:

Given that the rate of change of population with respect to time dP/dt is directly proportional to the population, P, we have

dP/dt ∝ P

dP/dt = kP

Given that dP/dt = 2 million insects per day and P = 10 million insects after 5 days, So,

2 = k × 10

k = 2/10

k = 1/5

So, dP/dt = kP

dP/dt = (1/5)P

The option C is correct

Differentiation

The rate of change of a function with respect to the given variable.

How to get the option?

The rate of change of population with respect to time is directly proportional to the population P. We have

[tex]\dfrac{\mathrm{d} P}{\mathrm{d} t} \propto P\\\\\dfrac{\mathrm{d} P}{\mathrm{d} t} = kP[/tex]

[tex]\dfrac{\mathrm{d} P}{\mathrm{d} t}[/tex] is 2 million insects per day and P = 10 million insects after 5 days. So

[tex]\begin{aligned} \dfrac{\mathrm{d} P}{\mathrm{d} t} &= kP\\2 &= 10k\\k &= \dfrac{1}{5} \\\end{aligned}[/tex]

Then

[tex]\dfrac{\mathrm{d} P}{\mathrm{d} t} = kP\\\\ \dfrac{\mathrm{d} P}{\mathrm{d} t} = \dfrac{1}{5} P[/tex]

Thus, option C is correct.

a cube has a lateral surface area of 64sq m find the total surface area of the cube

Answers

Answer:

384 square meters.

Step-by-step explanation:

Given that a cube has a lateral surface area of 64 square meters, to find the total surface area of the cube, the following calculation must be performed, knowing that the formula to calculate the area of a cube is to multiply by 6 (the number of sides of the cube) the area of one of its sides:

A x 6 = X

64 x 6 = X

384 = X

Thus, the area of the cube is 384 square meters.

The measure of Angle D is
degrees.
O=41 degrees

Answers

Answer:

49°

Step-by-step explanation:

O=41° and G=90° (because it is a right angle).  The sum of the interior angles of a triangle is 180°.  So, add the known angles, 41°+90°=131°.  Since the sum of all three angles needs to be 180°, subtract the known angles from the total, 180°-131°=49°, to find the unknown angle.  

The angle D in triangle OGD measures 49 degrees.

To find the measure of angle D in triangle OGD, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

Given that angle O is 41 degrees and angle G is 90 degrees, we can substitute these values into the equation:

Angle O + Angle G + Angle D = 180

41 + 90 + Angle D = 180

131 + Angle D = 180

Now, we can solve for angle D by subtracting 131 from both sides:

Angle D = 180 - 131

Angle D = 49

Therefore, angle D in triangle OGD measures 49 degrees.

Terry goes to the store to buy a shirt. The original price is $32. The shirt is
marked down 20%. When he gets to the check-out stand, he learns that
everything in the store is another 10% off of the marked down price. Which
dollar amount below is closest to the amount Terry paid for the shirt?

Answers

Answer:

The closest amount paid is $23

Step-by-step explanation:

Given

[tex]Price = \$32[/tex]

[tex]Mark\ down = 20\%[/tex]

Amount = 10% of Marked down price

Required

Determine the amount paid

First, we calculate the marked down price P2:

[tex]P_2 = Price(1 - Mark\ down)[/tex]

Substitute values for Price and Mark down

[tex]P_2 = \$32 * (1 - 20\%)[/tex]

Express percentage as decimal

[tex]P_2 = \$32 * (1 - 0.20)[/tex]

[tex]P_2 = \$32 * (0.80)[/tex]

Remove bracket

[tex]P_2 = \$32 * 0.80[/tex]

[tex]P_2 = \$25.6[/tex]

The payable amount is 10% off the marked down price,

This is calculated as:

[tex]Amount = P_2 - P_2 * 10\%[/tex]

Substitute $25.6 for P2

[tex]Amount = \$25.6 - \$25.6* 10\%[/tex]

Express percentage as decimal

[tex]Amount = \$25.6 - \$25.6* 0.10[/tex]

[tex]Amount = \$25.6 - \$2.56[/tex]

[tex]Amount = \$23.04[/tex]

The closest amount paid is $23

[tex]f(t) = 1 - \frac{cos\ t}{sec\ t}[/tex]

[tex]sec\ t = \frac{1}{cos\ t}[/tex]

1 1/2 hours

Time spent by Antonio in driving = 3 1/4 = 13/4

Time spent in gardening = 1 3/4 = 7/4

In order to find how much he spend driving than gardening, we can subtract 13/4 and 7/4.

13/4 - 7/4

Te denominator is same. So, we can directly subtract the numerators.

13-7/4

=6/4

= 3/2 = 1 1/2

Therefore, Antonio spent 1 1/2 hours more in driving than gardening.
