What is the domain and range of the function y = xn if n is an odd whole number? if n is an even whole number?

A. If n is odd, domain is (−∞,∞) and range is [0, ∞); if n is even, domain and range are both (−∞,∞).
B. If n is odd, domain and range are both (−∞, ∞); if n is even, domain is (−∞, ∞) and range is [0, ∞).
C. In both cases, domain is (−∞, ∞) and range is [0, ∞).
D. Domain and range in both cases is (−∞ , ∞ ).

Answer: 9

Concept:

The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half.

In other words, the median of a set of data is the middlemost number or center value in the set.

Solve:

STEP ONE: Line up the terms in the set from least to most

Given = 2, 7, 10, 8, 9, 10, 15

Line up = 2, 7, 8, 9, 10, 10, 15

STEP TWO: Find the middlemost number

Given = 2, 7, 8, 9, 10, 10, 15

Since it is an odd set, therefore there should be the equal number of terms in the lower and higher half.

There are in total seven terms, therefore, the 4th term would be the middlemost, which is [tex]\boxed{9}[/tex].

Answer:

number 3

Step-by-step explanation:

number 3 the answer is the third one

Answer:

hope it helps you........

Step-by-step explanation:

The midpoint formula is

[tex] (\frac{x1 + x2}{2} ) \: and \: ( \frac{y1 + y2}{2} )[/tex]

Where (x1,y1) is one pair of the points and (x2,y2) is the other pair of points.

The points are

(-5,-4)

(-3,3) So the midpoint is

[tex]( \frac{( - 5 + ( - 3)}{2} )\: and \:( \frac{ - 4 + 3}{2} )[/tex]

Which gives us

[tex] - 4 \: and \: - 0.5[/tex]

So the midpoint is

(-4,-0.5)

Answer:

y= -3x+4

Step-by-step explanation:

x+12=3y

(x+12)/3 = y

slope =

[tex] \frac{1}{3} [/tex]

the new slope = -3

Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b

4 = -3×(0) + b

b= 4

so y= -3x+4

Answer:

[tex] {f}^{ - 1} (x)= - \frac{4}{3} x + 8[/tex]

Step-by-step explanation:

[tex]f(x) = - \frac{3}{4} x + 6[/tex]

[tex]y = - \frac{3}{4} x + 6[/tex]

[tex]x = - \frac{3}{4} y + 6[/tex]

[tex] - \frac{3}{4} y + 6 = x[/tex]

[tex] - 3y + 24 = 4x[/tex]

[tex] - 3y = 4x - 24[/tex]

[tex]\boxed{\green{ {f}^{ - 1} (x)= - \frac{4}{3} x + 8}}[/tex]

Step-by-step explanation:

The sum of consecutive squares is

[tex]1^2+2^2+\dots+n^2=\frac16n(n+1)(2n+1)[/tex]

Therefore

[tex]1^2+2^2+\dots+30^2=\frac16(30)(31+1)(2\cdot30+1) = 9455[/tex]

Hi there!

I believe your answer is:  

17

»»————-　★　————-««  

Here’s why:  

⸻⸻⸻⸻

[tex]\boxed{\text{Solving for 'x'...}}\\\\2x + 12 = 3x - 5\\--------------\\\rightarrow 2x + 12 - 12 = 3x - 5 - 12\\\\\rightarrow 2x = 3x -17 \\\\\rightarrow2x -3x = 3x-3x - 17\\\\\rightarrow -x = - 17\\\\\rightarrow \frac{-x=-17}{-1} \\\\\rightarrow \boxed{x = 17}[/tex]

Answer:

3/2

Step-by-step explanation:

you basically just simplify the exponents first, and then simplify from there.

Step-by-step explanation:

#1

6 × n + 15 = -42

6n + 15 = -42

6n = -42 - 15

6n = -57

n = -57/6

n = -19/3

#2

b + 3/2b + b + 45 + 2b - 5 + 90 = 540

b + 1.5b + b + 45 + 2b - 5 + 90 = 540

5.5b + 130 = 540

5.5b = 540 - 130

5.5b = 410

b = 410/5.5

b = 74.5

Angles are

b = 74.5

1.5(74.5) = 111.75

74.5 + 45 = 119.5

2(74.5) - 5 = 144

Answer:

7

Step-by-step explanation:

49 is a perfect sqaure root cuz 7x7 = 49

Answer:

the first one: The coordinates of A' are (-2, 3)

and the last one: The coordinates of B' are (-2, 0) and the coordinates of C' are (2, -1).

Step-by-step explanation:

when you rotate a triangle counterclockwise by 90° you swap the numbers of the x and y coordinates.

like how the coordinates of B' were (0, 2) and became (-2,0) once the triangle was rotated.

Answer:

6

Step-by-step explanation:

plug in 8 for all p so 4^2 = 16 / 8 x 3 ---> 2 x 3 = 6

Answer:

V = π × r² × h

Step-by-step explanation:

All you need to do is multiply the base times the height and since the base is a circle whose formula is π × r², we get π × r² × h.

Answer: [tex]\bf \boxed{\bf V=\pi r^2 h}[/tex]

Step-by-step explanation:

[tex]\bf V=height \times (radius)^2\times \pi[/tex]

Answer:

y = 3/4x + 19/2

Step-by-step explanation:

m = 3/4. point (-6,5)

Point slope form:

y-5=3/4(x- -6)

y -5 = 3/4x + 18/4. 18/4 = 9/2

Y = 3/4x + 9/2 + 5. 5 times 2 plus 9 over 2 = 19/2

y = 3/4x + 19/2

Answer:

x = 5

Step-by-step explanation:

(5) + 20/2 = 3(5)

Answer:

D

Step-by-step explanation:

We just need to plugin the points to the equation 5x + 2y = 7.

If we plugin x = 8 and y = -33/2 we can easily see that

5x + 2y = 5(8) + 2(-33/2) = 40 -33 = 7

So D is the right answer

Answer:

D[(8,-33/2)]

Step-by-step explanation:

Post In a bit

Answer:D

Step-by-step explanation:

Answer:x=(c+ab)/3

Step-by-step explanation:

Add ab to c, then divide both sides by 3.

Answer:

AB+BC=AC

2x+6 +x+10=7x

3x+16=7x

16/4=x

X=4

First, [tex]y=7x[/tex] and when we plug in the point we get [tex]-8=7a\implies a=-\frac{8}{7}[/tex].
