Answer:

23.09 meters.

Step-by-step explanation:

Sin(60) = opposite / hypotenuse =  pole / steel wire

pole = 20 m

angle = 60 degrees.

sin(60) = 20/ hypotenuse       multiply both sides by the hypotenuse

hypotenuse * sin(60) = 20      divide by sin(60)

hypotenuse = 20 / 0.866        do the division    

hypotenuse = 23.09

The steel wire = 23.09 meters.

I cant really help you with the table but she will need $14.40 to pay for it. This is because since two cups cost $3.60 you multiply 3.60 by 4. I got the 4 by dividing 8 into 2 because 8 people and 2 cups each

Question 1(Multiple Choice Worth 2 points)
earnstyle [38]
These are 3 questions and 3 answers.

1) Find


\lim_{x \to \ 2^+} f(x)

Answer: 4.

Explanation:

The expression means the limit as the function f(x) approaches 2 from the right.

Then, you have to use the function (the line) that comes from the right of 2 and gets as close as you want to x = 2.

That is the line that has the open circle around y = 4, and that is the limit searched.

2) Use the graph to determine the limit if it exists.

Answer:

\lim_{x \to \ 2^-} f(x) = 3

\lim_{x \to \ 2^+} f(x)=-3

To determine each limit you use the function from the side the value of x is being approached.

Note, that since the two limits are different it is said that the limit of the function as it approaches 2 does not exist.

3) 
Answer: - 1


\lim_{x \to \ 3^-} f(x) = -1

To find the limit when the function is approached to 3 from the left you follow the line that ends with the open circle at (3, -1).

Therefore, the limit is - 1.

Four friends each ordered individual pizzas at a restaurant. Suzy ate 3/8 of her pizza. Ethan ate 3/5 of his pizza. Tenaya ate 4
Kay [80]

Answer:

Ethan and Tenaya ate more than half of their pizza.

Sam and Suzy ate less than half of their pizza.

Step-by-step explanation:

We have been given that each of the four friends ordered individual pizzas. They ate some part of the pizzas and we have to find who ate more than half of their pizza? Less than half?

Suzy ate 3/8 of her pizza. It means she ate 0.375 of her pizza which is less than half.

Ethan ate 3/5 of his pizza. It means he ate 0.6 of his pizza which is greater than half.

Tenaya ate 4/6 of her pizza. It means she ate 0.67 of his pizza which is greater than half.

Sam ate 1/3 oh his pizza. It means he ate 0.3 of his pizza which is less than half.

Hence, we can conclude that

Ethan and Tenaya ate more than half of their pizza.

Sam and Suzy ate less than half of their pizza.

A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find
lyudmila [28]

<u>Answer:</u>

f(x)=120000 \times (1.055)^{x}

<u>Step-by-step explanation:</u>

We are given that the present value for the home is $120,000 and the rate of interest is 5.5% i.e. 0.055.

We will use the following formula:

f(x)=P \times (1+r)^{x}

where P is the present value, r is the rate of interest and x is the number of years.

Substituting the values in the above formula to get:

f(x)=120000 \times (1+0.055)^{x}

f ( x ) = 120000 \times ( 1.055 ) ^ { x }
