Domain and range of y=0.025x^2

1 answer:

6 0

Since it's not a domain restricted function anywhere, the domain of this function is (-∞, ∞). Because the x is squared, you will never get a negative answer, and therefore, the range is either (0, ∞) or {x: x > 0}. Hope this helps you out!

Find the exact length of the third side. 51

Nesterboy [21]

Answer:

Step-by-step explanation:

You can use the Pythagorean Theorem to solve this:

$a^{2} + b^{2} = c^{2}$

The legs of the triangle are put into either a or b and the hypotenuse is put into c. In this case, they've already given you the hypotenuse, but now you need to find the leg:

$45^{2} + b^{2} = 51^{2}$

2025 + $b^{2}$ = 2601

Subtract 2025 from both sides:

2025 + $b^{2}$ = 2601

-2025 -2025

_____________

$b^{2}$ = 576

Square root:

$\sqrt{b^{2} } = \sqrt{576}$

b = 24

If BH = 3, BF = 10, GH = 2, find HD

s344n2d4d5 [400]

Answer:

HD = 10.5

Step-by-step explanation:

Given BH = 3, GH = 2, BF = 10

Step 1: To find HF:

HF = BF – BH

HF = 10 – 3

HF = 7

Step 2: To find HD:

We know that if two chords intersects inside a circle, the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.

⇒ GH × HD = BH × HF

⇒ 2 × HD = 3 × 7

⇒ HD = 10.5

Hence, the value of HD = 10.5.

I hope this helps a little bit.

This company will begin to make a profit after producing more than ______ units.

grandymaker [24]

The costs equal one another at approximately 2450 units. After that, you can see that the revenue line has a much steeper slope than the cost line and that means that revenue is greater than the costs after the point where they intersect. They begin to make a profit after 2450 units are produced.
