Answer:

Domain: [10, ∞)

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

Step 1: Write equation

f(x) = √(x - 10)

We know that if we get negatives under the square root, we would get imaginary numbers.

Our domain to include all x-values would have to be bigger than 10:

f(10) = √(10 - 10) = √0 = 0

If the number is smaller than 10, we get: f(9) = √(9 - 10) = √-1 = i

Therefore, our real numbers domain would be [10, ∞) or x ≥ 10.

Find the missing part.
Katarina [22]

Answer:

z = 15[\frac{\sqrt{3}}{2}]

Step-by-step explanation:

To find the Z-side, we must take the cosine of the 30-degree angle of the main triangle

We know that the cosine of an angle is defined as:

cos(30) = \frac{adjacent\ side}{hypotenuse}

cos(30) = \frac{\sqrt{3}}{2}

\frac{\sqrt{3}}{2}} = \frac{z}{15}

Then:

z = 15[\frac{\sqrt{3}}{2}}]

Finalmente the side z is:

z = 15[\frac{\sqrt{3}}{2}}]

A jar has 5 red marbles, 3 blue marbles, and 2 green marbles. what is the probability that you would choose a red marble, return
denis23 [38]

Answer:

In Fraction  = 10/100  simplified =  1/10

Decimal = 0.1

Percentage = 10%

Step-by-step explanation:

We add all marbles = 5+ 3+ 2 = 10

Event 1 = Red  = 5/10

Event 2 = Green = 2/10

We follow this path and multiply =  2 x 5 /  10 x 10 =  10/100 = 1/10

What is the slope of (-1,-7) (1,5)
vodka [1.7K]
To find slope, use the form y1 - y2/x1 - x2. Using these points, that would look like:
-7 - 5/-1 - 1 or -12/-2, which simplifies to 6.
The slope is 6. Hope this helps with slope.
