What is the domain of the function y = StartRoot x 6 EndRoot minus 7?.

Answers

Answer 1

A function is a mapping from domain to range. The domain of the function [tex]y = \sqrt{x+6} - 7[/tex] is given as: [tex]x \geq -6[/tex] or [tex]x \in [-6, \infty)[/tex] (both are same)

What is domain and range of a function?Domain is the set of values for which the given function is defined.Range is the set of all values which the given function can output.

One method of finding the domain of a function is to start by finding the values for which it isn't defined.

Assuming that the function  [tex]y = \sqrt{x+6} - 7[/tex] is defined for only real numbers, then, as we know that:

[tex]\sqrt{x}[/tex] exists only if x is non-negative, which means for  [tex]\sqrt{x+6}[/tex] to be defined, we need

[tex]x + 6 \geq 0\\x \geq -6[/tex]

No other way is there for the function to be non-existing.

Thus, the values on which the function is defined is all real numbers bigger or equal to -6. This is the domain of the given function.

Thus,  the domain of the function [tex]y = \sqrt{x+6} - 7[/tex] is given as: [tex]x \geq -6[/tex] or [tex]x \in [-6, \infty)[/tex] (both are same)

how would i find the perimeter and area of this

Answers

Answer: P: 6x - 6 + (pi * x/2) A: 3x^2 - 3x - (pi * (x^2)/4)

Step-by-step explanation:

The missing section is a quarter of a circle. It is the same length at 90 degrees difference following an arc. This radius is X, same as the smaller length of the rectangle. The longer length of the rectangle is 2x-3+x, or 3x-3.

Area: Rectangle area is X * (3x-3) or 3x^2 - 3x. Subtract the missing piece. The full area of the circle would be pi * x^2. Divide by 4 for a quarter circle. So the full area would be 3x^2 - 3x - (pi * (x^2)/4).

Perimeter. x + 2x-3 + 3x-3 + the arc. The arc is a quarter of the circle's circumference. pi * 2x over 4. So total perimeter would be 6x-6 + (pi * 2x/4 or pi * x/2).

Answers

okay so let's make this fraction bigger. 2/3 x 2 would equal 4/6 which means megan uses 1/6 per cup of trail mix. so if she wanted to make 9 batches of trail mix she would use 2 1/6 but let's make that into an improper fraction.. aka 13/6 .. we cannot simplify that so megan would need 2 1/6 cups of almonds

A standard die is rolled two
times. What is the probability
that it lands on 1 both times

Answers

Answer:

1/6

Step-by-step explanation:

If you roll a 1 then on the second roll (for a fair 6 sided die) the probability that the second roll is a 1 is 1/6 (assuming independence.

Answer:

1/6

Step-by-step explanation:

If the die is fair (and we will assume that all of them are), then each of these outcomes is equally likely. Since there are six possible outcomes ( A standard die has 6 Number { 1,2,3,4,5,6 } ) , the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on.

Answers

The equation 60.1 = 7.2x + 2.5 can be used to find the number of oranges in the bag is 8.

What is the linear system?

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

A grocer sells oranges in bags. Each empty bag weighs 2.5 ounces and each orange weighs 7.2 ounces.

Khalil buys a bag of oranges that weighs 60.1 ounces.

Let x be the number of oranges.

Then the equation will be

y = 7.2x + 2.5

For y = 60.1, the value of x is

[tex]\rm 60.1 = 7.2x + 2.5\\[/tex]

On simplifying, we have

x = 8

Thus, the number of oranges in the bag is 8.

B: This one you can forget about the negative for the first bit. Just divide 15 by 3 to get 5. Now the negative is only on one side of the equation so therefore we add the negative back into our answer. Final Answer : -5

C: Just divide 32 by 4 to get 8. No removal or substitution is needed for this one because both numbers are positive. Final Answer : 8
