1. Point B is located at (-4, -6). Where is the location of B’ after a reflection over the y-axis?
a. (4, -6)
b. (-4, 6)
c. (-6, -4)
d. (-6, 4)

Answers

Answer 1

Answer:

a. (4, -6)

Step-by-step explanation:

When a reflection over the y-axis takes place, the x value will change its sign, while the y value will remain the same. Test this using a graph if needed. Recall that a reflection over the n axis will not change the value of the n coordinate.

trig . plz help me with this

Answers

Answer:

x=10.04

Step-by-step explanation:

let the triangle sides to be ABC, given <A=90, <B=42 &<C=?

find angle C first

<A+<B+<C=180

90+42+<C=180

<C=180-132

<C=42°

Now use sine rule to find the value of X

a/sinA =c/sinC. where, small letters is equal to sides and capital letters is equal to angles. a=15. c=x

A=90. C=42

15/sin90°=x/sin42°

cross multiply

15*sin42°=x*sin90°

make x subject of the formula

x=(15*sin42°)/sin90°

x=10.04

Given:

A regular pentagon with side 8 cm and apothem 6 cm.

To find:

The area of the given regular pentagon.

Solution:

The area of a regular polygon is:

[tex]A=\dfrac{n\times s\times a}{2}[/tex]

Where, n is the number of sides of the regular polygon, s is the side length and a is the apothem.

In a regular pentagon the number of sides is 5.

Substituting [tex]n=5,s=8,a=6[/tex] in the above formula, we get

[tex]A=\dfrac{5\times 8\times 6}{2}[/tex]

[tex]A=\dfrac{240}{2}[/tex]

[tex]A=120[/tex]

The area of the regular pentagon is 120 cm². Therefore, the correct option is C.

the graph shows the square root parent function. which statement best describes the function?

Answers

Answer:

Wouldn't it be D?

Step-by-step explanation:

A, B, and C both kinda are wonky and B definitely is wrong.

C is also wrong because it is not decreasing unless you are going backwards, which isn't how functions are supposed to be used.

A is false because it says when x is less than 0 (which isn't on the parent function) then it increases, which isn't possible.

D is your best bet.

The function is always increasing if you look at it.

It looks like it might stop, but will continue forever in a positive direction even though it looks like it would become a straight line eventually.

The function is increasing when x > 0

The graph shows the square root parent function is always increasing.

What is square root parent function?

The parent function of a square root function is y = [tex]\sqrt{x}[/tex] . Its graph shows that both its x and y values can never be negative. This means that the domain and range of  y = [tex]\sqrt{x}[/tex] are both (0, infinity).

As we can see from the graph where the value of x increases the value of function also increases or

We can say that for [tex]x_{1} < x_{2}[/tex]

[tex]f(x_{1}) < f(x_{2})[/tex] for ∀ x > 0

Hence for x > 0 the function is increasing.

A manufacturer sent free boxes of tissue to 100 random homes in Miami at the beginning of January. At the end of January, a representative found an average of 3 boxes of tissues had been used in each home. The representative concluded that the average home in the United States uses 36 boxes of tissue per year. Is his conclusion correct

Answers

Answer:

conclusion of representative is incorrect

Step-by-step explanation:

The total random samples of 200 homes in Miami uses 3 boxes of tissues per home.

This is true only for Miami. Miami's population is not the correct representation of the population of USA.

Also, there are several other factors such as population group residing in Miami, their education level, heath etc.  plays a major role as a variable. These variables in case of USA will be entirely different.

Hence, conclusion of representative is incorrect
