Answer:

$\large\boxed{x=26}$

Step-by-step explanation:

$\text{The angle}\ x^o\ \text{and}\ 64^o\ \text{together from both sidesr form a right angle.}\\\text{Therefore we have the equation:}\\\\x^o+64^o=90^o\qquad\text{subtract}\ 64^o\ \text{from both sides}\\\\x^o+64^o=90^o-64^o\\\\x^o=26^o$

Whixh statement is true about the graphs of the functions shown below?

Nata [24]

Answer:

Step-by-step explanation:

Since G(0) = g(0) = 20, the parabolic graphs of these functions share a y-intercept: (0, 20).

Completing the square puts these equations into vertex form, which simplifies comparisons of the graphs:

G(x) = 2x^2 - 12x + 20 becomes

2(x^2 - 6x + 9 - 9) + 20, or

2(x - 3)^2 - 18 + 20, or 2(x - 3)^2 + 2. Comparing this result to

a(x - h)^2 + k, we see that the vertex is located at (3, 2).

Going through the same process for g(x) 2x^2+12x+20, we get:

g(x) = 2(x + 3)^2 + 2, whose vertex is at (-3, 2).

Next time, please include ALL info pertaining to your question, including the set of possible answer choices. Thank you.

) An instructor gives his class a set of 18 problems with the information that the next quiz will consist of a random selection

RSB [31]

Answer:

The probability the he or she will answer correctly is 1.5%

Step-by-step explanation:

In all, there are 18 problems. In this question, the order of which the problems are sorted for the quiz makes no difference. For example, if the question A of the quiz is P1 and question B P2, and question A P2 and question B P1, it is the same thing.

There are 18 problems and 9 are going to be selected. So, there is going to be a combination of 9 elements from a set of 18 elements.

A combination of n elements from a set of m objects has the following formula:

$C_{(m,n)} = \frac{m!}{n!(m-n)!}$

In this question, m = 18, n = 9. So the total number of possibilities is:

$T_{p} = C_{(18,9)} = \frac{18!}{9!(18-9)!} = 48620$

Now we have to calculate the number of desired outcomes. This number is a combination of 9 elements from a set of 13 elements(13 is the number of problems that the student has figured out how to do).

Now, m = 13, n = 9. The number of desired possibilities is:

$D_{p} = C_{(13,9)} = \frac{13!}{9!(13-9)!} = 715$
