Answer:

Domain is all real numbers; Range is all numbers less than or equal to 0

Step-by-step explanation:

Domain covers x values, range covers y values.  The domain of an x^2 parabola, which is what this is, has a domain of all real numbers.  Meaning that while the branches of the function keep going up and up and up or down and down and down, the values of x will never stop growing.

The range here is indicative of the lowest y value to the highest that the function covers.  In this case, since the parabola is upside down, we have the highest to the lowest.  The highest that the function goes up the y axis is right at the origin, where y = 0.  Then it drops down into forever.  So the range is all values of y less than or equal to 0

The Domain of [tex]f(x)[/tex] is all the real numbers, and

The Range of [tex]f(x)[/tex] is  [tex]y\le0[/tex] or [tex]f(x)\le0[/tex]

The diagram shows the graph of the quadratic function

[tex]f(x)=-x^2[/tex]

The domain of [tex]f(x)[/tex] is all the real numbers, since the function has defined values for all real values of [tex]x[/tex].

The range of [tex]f(x)[/tex] is the set of values that [tex]f(x)[/tex] can assume. The square function has a range

[tex]\{y \text{ }|\text{ }y=x^2\text{ and }y\ge0\}[/tex] or the half-open interval [tex][0,\infty)[/tex].

This means that the negative of the square function will have the range

[tex]\{y \text{ }|\text{ }y=-x^2\text{ and }y\le0\}[/tex] or the half-open interval [tex](-\infty,0][/tex].

So, the domain of [tex]f(x)[/tex] is the open interval [tex](-\infty,\infty)[/tex] (all the real numbers), and the range of [tex]f(x)[/tex] is the half-open interval [tex](-\infty,0][/tex] (or, [tex]y\le0[/tex])

x = 26.6 feet

Answer:

a) Acute

Step-by-step explanation:

   To clasify the triangle as Acute, Right, or Obtuse, we use the converse of the pythagorean theorem and see if c^2 is greater, less than, or equal to b^2+a^2.

So 16^2 ? 11^2 + 12^2

Since 11^2 +12^2 = 265 and 16^2 is 256, c^2 is less than b^2+a^2. So the triangle is acute.

Answer:

  a)  Acute

Step-by-step explanation:

If 11 and 12 were the legs of a right triangle, the length of the hypotenuse would be ...

  √(11² +12²) = √(121 +144) = √265 ≈ 16.3

The actual length of the longest side is shorter, so the opposite (largest) angle measure will be less than 90°. The triangle is acute.

Option B

Answer:

20

Step-by-step explanation:

The geometric mean of n numbers is the n-th root of their product. For two numbers, it is the square root of their product:

geometric mean = √(8·50) = √400 = 20

The answer is: 20

My work: √8*50 = √400 = 20

You have to take the square root of 8 multiplied by 50.  With that, you would get 400, which is still squared because you have to get the numbers inside of the square root to one number.  After that, you can now take the square root of the number that is inside of it, which in this case it is 400.  The square root of 400 is 20.

Answer:

2500

Step-by-step explanation:

Let the first square number be [tex]x^2[/tex] then the next square number is [tex](x+1)^2[/tex].

The difference between these two consecutive numbers is 99.

This implies that:

[tex](x+1)^2-x^2=99[/tex]

We expand to get:

[tex]x^2+2x+1-x^2=99[/tex]

Simplify:

[tex]2x=99-1[/tex]

[tex]2x=98[/tex]

Divide both sides by 2

[tex]x=49[/tex]

Therefore the value of the larger perfect number is

Answer:

A = 32°, a = 19, b = 14, B=22.98°, C = 125.02°, c = 29.36

Step-by-step explanation:

We have two sides of the triangle and we have an angle.

A = 32 °, a = 19, b = 14

We use the sine theorem to find the angle B.

We know that according to the sine theorem it is true that:

[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]

[tex]\frac{sin(32\°)}{19}=\frac{sin(B)}{14}[/tex]

[tex]sin(B)=14*\frac{sin(32\°)}{19}\\\\B=Arcsin(14*\frac{sin(32\°)}{19})\\\\B=22.98\°[/tex]

We know that the sum of the internal angles of a triangle is always equal to 180.

So:

[tex]C=180-32-22.98\\\\C=125.02\°[/tex]

Finally we find the c side

[tex]\frac{sin(A)}{a}=\frac{sin(C)}{c}[/tex]

[tex]\frac{sin(32\°)}{19}=\frac{sin(125.02)}{c}[/tex]

[tex]0.02789=\frac{sin(125.02)}{c}[/tex]

[tex]c=\frac{sin(125.02)}{0.02789}\\\\c=29.36[/tex]

D is the correct answer

the result of subtracting (5x + 3) from (9x - 7) is 4x - 10. Therefore, the correct option is C: 4x - 10.

To subtract (5x + 3) from (9x - 7), we need to distribute the negative sign to all the terms in (5x + 3) and then perform the subtraction term by term.

(9x - 7) - (5x + 3)

= 9x - 7 - 5x - 3

Now, combine like terms:

= (9x - 5x) + (-7 - 3)

= 4x - 10

So, the result of subtracting (5x + 3) from (9x - 7) is 4x - 10. Therefore, the correct option is C: 4x - 10.

Answer:

400 units³

Step-by-step explanation:

The volume (V) of the square pyramid is

V = [tex]\frac{1}{3}[/tex] area of base × height (h)

where h is the perpendicular height.

Consider the right triangle formed by a segment from the vertex to the midpoint of the base and the slant height ( the hypotenuse )

Using Pythagoras' identity on the right triangle

h² + 5² = 13²

h² + 25 = 169 ( subtract 25 from both sides )

h² = 144 ( take the square root of both sides )

h = [tex]\sqrt{144}[/tex] = 12

Area of square base = 10² = 100, hence

V = [tex]\frac{1}{3}[/tex] × 100 × 12 = 4 × 100 = 400

To find out how many minutes are in 222 days, multiply the number of days (222) by the number of hours in a day (24) and then by the number of minutes in an hour (60). The result is 319,680 minutes.

Explanation:

The student is asking how many minutes are in 222 days. We begin the conversion using the provided information:

There are 24 hours in 1 day

There are 60 minutes in 1 hour

Now, we just need to multiply the number of days by the number of hours in a day, and then by the number of minutes in an hour, to get our answer.

222 days × 24 hours/day × 60 minutes/hour = 319,680 minutes

There are 319,680 minutes in 222 days.

Answer:

arc NO has measure 48

Step-by-step explanation:

We assume all measures are in consistent units (degrees or something similar). The two inscribed angles intercept the same arc, so are congruent:

9x -3 = 4x +12

5x = 15 . . . . . . . add 3-4x

x = 3 . . . . . . . . . divide by 5

The measure of the inscribed angle is then ...

4x +12 = 4(3) +12 = 24

That is half the measure of the arc, so the measure of arc NO is ...

arc NO = 2·24 = 48

Answer:

48°

Step-by-step explanation:

I'm actually just assuming that you mean arc NO.  Proceeding with that...

Angle NMO is an inscribed angle which intercepts arc NO.  Angle NPO is also an inscribed angle that intercepts arc NO.  Because they both intercept the same arc, both inscribed angles have the same measure.  Therefore,

9x - 3 = 4x + 12

Solving for x:

5x = 15

x = 3.  Plug 3 in for x in either one of the equations to get that angles NMO and NPO measure

9(3) - 3 = 24°

The rule is that inscribed angles measure HALF of the arcs they intercept, so the measure of arc NO is 48°

1. False. [tex]f'(c)=0[/tex] does not necessarily mean that [tex]f(c)[/tex] is a maximum or minimum. It could just as easily be a saddle point.

2. True. If [tex]f'(x)=0[/tex] for all [tex]x[/tex] in [tex](a,b)[/tex], then [tex]f[/tex] must be constant on that interval.

3. False. In order for the MVT to apply, [tex]f[/tex] must be continuous on the closed interval. But [tex]\dfrac1{x^2}[/tex] does not exist at [tex]x=0[/tex].

The first statement about f'(c)=0 implying a local maximum or minimum is true. The second statement that if f'(x)=0 on an interval implies the function is constant is also true. Lastly, the Mean Value Theorem cannot be applied to f(x) = 1/x² on the interval [-1, 1] because the function is not continuous at x=0.
