O A. Acute
O B. Obtuse
O C. Right
O D. None of these
Answers
The triangle above is an obtuse triangle.
Acute triangle:
Acute triangle are triangles in which the internal angles are acute angles. This means the angles are less than 90 degrees.
Obtuse triangle
Obtuse triangle are triangle in which one of the internal angles measure more than 90 degrees.
Right angle triangleRight angle triangle are triangles that have one of its internal angles as 90 degrees
Therefore, base on our definition of this triangles, the triangle is an obtuse triangle.

Answer:
(x^(1/2))^2 = x^(2/2) = x
Step-by-step explanation:
The square root of a number, when multiplied by itself, gives the original number.
(√x)(√x) = x
The rule for exponents is that powers of the same base, when multiplied, will be the base to the sum of those powers.
(a^b)(a^c) = a^(b+c)
Also, the first power of a number is that number itself.
__
[tex]x^{\frac{1}{2}}\times x^{\frac{1}{2}}=x^{\frac{1}{2}+\frac{1}{2}}=x^1=x\\\\ \text{Compare to ...}\\\\ \sqrt{x}\times\sqrt{x}=x[/tex]
Answer:
Squaring and square root are inverses, so one should "undo" the other. That is, squaring the square root of a number results in the number. Using the power of a power rule, you multiply the exponents. Since a number to the first power is itself, the product of the exponents must equal 1. This means that the power of the square root must be the reciprocal of 2, or one half.

A researcher observes the level of aggression of six 5-year-old boys over the course of a school day. The number of incidents for the group of boys was 2, 4, 6, 12, 8, 10. What is the mean number of aggressive acts for this group of children
Answers
Answer:
7Step-by-step explanation:
Mean number = Sum of all the numbers/ Total number of old boys
Given the data
2, 4, 6, 12, 8, 10
Sum = 2+4+6+12+8+10
Sum = 42
Total number of old boys = 6
Substitute into the formula
Mean number of aggressive acts = 42/6
Mean number of aggressive acts = 7
Hence the mean number of aggressive acts for this group of children is 7

Answer:
180 degrees
Step-by-step explanation:
Lets call the unknown Angle next to angle C "ANGLE D"
1. Your given the angle 45 degrees.
2. (45 degree angle) can correspond to Angle D,
because of the alternate exterior angles definition- two lines (angles) that are on diagonal opposite sides of one another outside of the two parallel lines.
3: (45 degree angle) is an alternate exterior angle to its corresponding diagonal angle Angle D, this can also be said for (Angle C) and (angle B).
4: Now that the angles are known- (Angle C) is an alternate exterior angle to (Angle B). (45 degree angle) is an alternate exterior angle to Angle D
We can now use
The alternate Exterior angles Theorem- If two parallel lines are intersected by a transversal, then the alternate exterior angles are congruent.
4: we now know that (45 degree angle) is congruent to Angle D. And (angle C) is congruent to (angle B).
-Angle D and (45 Degree angle) are both 45 degrees since they are both alternate exterior angles to one another. And (Angle C) and (Angle B) have the same angle measure because they are alternate exterior angles to one another.
5: take a look at (angle C) and Angle D notice the transversal- (line that intersects two parallel lines), and how it creates a linear pair. Notice that the transversal has created the angles of (angle B) and (45 degree angle) to be linear pairs as well.
- Linear Pair definition- If two adjacent lines have rays pointing in opposite directions they are linear pairs.
Also the definition of a Linear Pair identifies as Supplementary. Supplementary is an angle that has a total of 180 degrees.
6: If (45 degree angle) and Angle B make a linear pair, and linear pairs have a total of 180 degrees, then solve for the angle measure of (angle B)
180= 45 + measure of (angle B)
180-45= 135
135 = measure of (angle B)
45 + 135= 180 degrees
7: The measure of (Angle B) is 135 degrees and since (Angle B) is congruent to (Angle C), the measure of (Angle C) is 135 degrees.
Therefore, (45 degree angle) and (Angle B) are 180 degrees total and (Angle C) and (Angle D) are 180 degrees total.
Now, that all exterior angle measures are found, it can be concluded that Angle A) is the same as the total measure of its exterior angle, since it is the same line that makes up the linear pair.
Therefore, (Angle a) is 180 degrees.

Roxie is picking out some movies to rent, and she is primarily interested in horror films and foreign films. She has narrowed down her selections to 20 horror films and 8 foreign films. Step 2 of 2 : How many different combinations of 3 movies can she rent if she wants at least two horror films
Answers
Answer:
2470
Step-by-step explanation:
Roxie must pick 3 movies from 20 horror films and 8 foreign films with at least two horror films.
i) She can pick 2 horror films and 1 foreign film
The number ways this is possible = C(20, 2) * C(8, 1)
[tex]C(20,2)=\frac{20!}{(20-2)!2!}=190\\\\C(7,1)=\frac{7!}{(7-1)!1!}=7[/tex]
The number ways this is possible = C(20, 2) * C(8, 1) = 190 * 7 = 1330
ii) She can pick 3 horror films
The number ways this is possible = C(20, 3)
[tex]C(20,3)=\frac{20!}{(20-3)!3!}=1140\\\\[/tex]
The number ways this is possible = C(20, 3) = 1140
The number of ways of picking 3 movies from 20 horror films and 8 foreign films with at least two horror films = pick 2 horror films and 1 foreign film + pick 3 horror films
The number of ways of picking 3 movies from 20 horror films and 8 foreign films with at least two horror films = 1330 + 1140 =2470

Step-by-step explanation:
Given two functions are:
[tex]f(x) = -x^2-1\\g(x) = x+5[/tex]
we have to find the composition of f and g which can also be written as: fog(x) or f(g(x))
The method to find the composition is that we will put the function g in place of x in function f
[tex]f(g(x)) = -(x+5)^2-1\\=-(x^2+25+10x)-1\\=-x^2-25-10x-1\\=-x^2-10x-26[/tex]
Hence,
The composition of f(g(x)) is:
[tex]f(g(x)) = -x^2-10x-26[/tex]
