<span>The expression 2x + 50 represents the elevation above sea level of the climber. It can be written as a function as follows:

f(x) = 2x + 50 where f(x) is the height and x is time.

We can obtain the initial height when we set time 0 in which the climber has not started climbing yet. Therefore, the initial height of the climber would be 50 meters above sea level.</span>

Answer: 50 meters

Step-by-step explanation: 2 is the amount of meters climbed every minute, for example 2 * 10 (x) = 20 meters in 10 minutes. So the starting point is 50 meters above sea level.

Answer:

70° is your measurement for ∠t.

Step-by-step explanation:

Note that a straight line has an angle of 180°

It is given to us that ∠r and ∠t = 180°, and that m∠r = 110°

Plug in 110 for ∠r

110 + ∠t = 180

Isolate ∠t. Note the equal sign, what you do to one side, you do to the other. Subtract 110 from both sides

110 (-110) + ∠t = 180 (-110)

∠t = 180 - 110

∠t = 70

70° is your measurement for ∠t.

A family plans to have 3 children. For each birth, assume that the probability of a boy is the same as the probability of a girl

Ugo [173]

Answer:

c. 0.75

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

We have the following sample space

That is, the possible outcomes.

I am going to call boys b and girls g

b - b - b

b - b - g

b - g - b

b - g - g

g - b - b

g - b - g

g - g - b

g - g - g

Total outcomes:

8 outcomes

What is the probability that they will have at least one boy and at least one girl?

Desired outcomes:

At least one boy and at least one girl

b - b - g

b - g - b

b - g - g

g - b - b

g - b - g

g - g - b

Six desired outcomes.

Probability

$P = \frac{6}{8} = 0.75$

The correct answer is:

c. 0.75

The first five terms of an arithmetic sequence are 8, 13/2, 5, 7/2, and 2. Which function, f(x), could be used to describe the x

juin [17]

Answer:

f(x) = 8 - 1.5x

Step-by-step explanation:

Here, we want to write a function that can be used to describe the x th term of the sequence

Mathematically, this can be calculated by looking at the numbers in the sequence

The difference between each successive term

is -1.5 ( 6.5-8, 3.5 -5)

So the formula for then x th term will be;

f(x) = 8 - 1.5x

where x refers to the number of the term , for example the 4th term
