Explanation:

Hello! Please remember to formulate complete questions to receive accurate answers. I will assume that the depicted function derives from:

$f(x)=\left(x-4\right)^{2}+5$

This describes the equation of a parabola that opens upwards, with its vertex positioned at:

$V(4,5)$

The graph below illustrates this function. What is true about the graphed function f(x)?

It is accurate that the domain consists of all real numbers, as this is a polynomial function.

It is also correct that the range includes all real numbers where y ≥ 5

It is indeed true that this parabola opens upwards

It is valid to say it does not intersect the x-axis

Zina [12379]

Answer:

8% likelihood that Anthony may soon join the Acme golf team

Step-by-step explanation:

The probabilities are as follows:

10% chance of being hired by the corporation.

If hired, an 80% probability of making the golf team is expected.

Given this information, we can calculate the probability of Anthony soon playing on the Acme golf team as:

80% of 10%

Thus

P = 0.8*0.1 = 0.08

8% chance that Anthony will soon be part of the Acme golf team

A series contains 18 numbers and has a sum of 4,185. The last number of the series is 275. What is the first number?

Inessa [12570]

The formula for the sum of an arithmetic series is expressed as:
Sn=n/2(a1+an)
where:
n=total terms
a1=the initial term
an=the final term
given
n=18, an=275, Sn=4185
substituting these values into the equation results in:
4185=18/2(a1+275)
after simplification, we obtain:
4185=9(a1+275)
dividing by 9 yields:
465=a1+275
therefore
a1=465-275
a1=190

Conclusion: the first term is 190
