Sally's cell phone bill os expected to increase by 7.5% next year . If b represnts the current bill, which expression represent the expected cost of the cell phone bill next year?

Answers

Answer:

The expression represent the expected cost of the cell phone bill next year is: c=1.075b.

Step-by-step explanation:

With the information provided, you can say that the expected cost of the cellphone bill next year would be equal to the current bill multiplied for 1 plus the increase in decimal numbers, so the increased amount is added to the current cost. The equation would be:

c=b*(1+0.075)

c=b*1.075

c=1.075b

According to this, the answer is that the expression represent the expected cost of the cell phone bill next year is: c=1.075b.

A plane is at cruising altitude of 10,200 feet. If the angle of depression to the run way is 18 degrees, what is the distance, to the nearest foot, from the plane to the run way

Answers

Answer: [tex]33,007.9\ ft[/tex]

Step-by-step explanation:

Given

The plane is cruising at an altitude of [tex]h=10,200\ ft[/tex]

The angle of depression is [tex]\theta=18^{\circ}[/tex]

Suppose the distance of the plane to the runway is x

Answers

Answer: 13

Step-by-step explanation:

Answer:

Step-by-step explanation:

Givens

r = 20 mm

Volume = 16328

h = ?

Formula

V = pi * r^2 * h

Solution

16328 = 3.14 * 20^2 * h

16328 = 3.14 * 400 * h

h = 16328/(3.14 * 400)

h = 16328 / 1256

h = 13

What is the scale factor from AABC to ADEF?

Answers

Answer:

C. 1/12

Step-by-step explanation:

The scale can be calculated by comparing side lenghts

AC is similar to FD and AB is similar to  FE and BC is similar to ED

AB = 2 and FE = 24 so AB/FE is = 2/24 that's simplified is 1/12

Line BC is tangent to the circle centered at A. Find the measure of angle BCA. Explain or show your reasoning.

Answers

Answer:

[tex] m\angle BCA= 33\degree[/tex]

Step-by-step explanation:

[tex] In\: \odot A[/tex] BC is tangent to the circle at point B.

Therefore, by tangent-radius theorem:

[tex] \therefore AB\perp BC[/tex]

[tex] \therefore \angle ABC = 90\degree [/tex]

[tex] In\: \triangle ABC, [/tex]

[tex] m\angle ABC +m\angle BAC +m\angle BCA= 180\degree [/tex]

[tex] 90\degree+57\degree +m\angle BCA= 180\degree [/tex]

[tex] 147\degree +m\angle BCA= 180\degree [/tex]

[tex] m\angle BCA= 180\degree - 147\degree[/tex]

An amusement park charges an entrance fee of $20 and the rides cost $4 each. Suppose you write a function for the total cost for entering the park and riding a. Number of the rides. What is the domain of the function based on the given context?

Answers

Answer:

With the information provided, you can say that the total cost is equal to the entrance fee plus the price per ride for the number of rides, which would be:

C(x)=20+4x,where:

x is the number of rides

The domain of the function refers to all the inputs that the function can have and in this case, the domain consists of all real numbers greater than or equal to zero since x refers to the number of rides and it can't have a negative number.

How do you solve:

g(x) = x - 2

( I think the answer is 2 but how?!)

Answers

Answer:

x-2 =0

x=2

Step-by-step explanation:

we take -2 to the anther side it becomes 2

Answer:

-2

Step-by-step explanation:

A function is a rule for working out the values y for the given values x

For example, h = 3x and y = x^2 are functions. The notation g(x) is read as g of x. g is the function. g(x) = 3x means the function of x is 3x

So, when solving to find the value of x, you must substitute x for any given value.

For example, f(x) = 10/x. Work out f(5), you must substitute the 5 into the denominatior of the fraction 10/x . This becomes 10/5, which equals to 2.

But for your question, to find the value of x, substitute x with 0

You end up with -2

Just like engines, they need a type of fuel. Hurricanes form over warm ocean waters near the equator. For hurricanes, their fuel is warm, moist air. When hurricanes form, the warm, moist air above the ocean rises upward from close to the surface of the water. Because the warm air rises, it results in less air under the surface of the water. This area with less air is known as an area with low pressure.Air from areas surrounding this low pressure space pushes in to the area. This fills the low pressure area. The new air in this space becomes warm and moist and also rises. As the air continues to rise, the air surrounding the space swirls in to take its place. This process of air swirling in to replace air that has risen continues. Eventually, the moisture in the air forms clouds.The wind and the clouds that form create a system. A system is a pattern of weather. The system of clouds and winds continues to spin and grow. The water evaporating from the ocean's warm surface acts as the fuel, which is what helps this spinning and growing. The system rotates faster and faster until the eye of the storm forms in the center area. Ironically, the eye of the storm is the calmest part, and it has very low air pressure. The higher pressure above the hurricane continually flows down into the eye.Select the detail from the excerpt that supports the main idea of this part of the article.
