Answer:

The range of the graph is all real numbers greater than or equal to 0.

Step-by-step explanation:

we have

$y=\sqrt{x}$

using a graphing tool

The graph in the attached figure

step 1

Find the domain

we know that the radicand of the function must be greater than or equal to zero

The domain is the interval ------> [0,∞)

$x\geq0$

All real numbers greater than or equal to zero

step 2

Find the range

The range is the interval -----> [0,∞)

$y\geq0$

All real numbers greater than or equal to zero

How do you solve g= y-c+x for x

SOVA2 [1]

To solve for x just isolate x by moving the other variables so....:
First add c to both sides
g+c= y+x
Subtract y from both sides
g+c-y= x
That should be your final answer (we cannot come up with an actual digit for x because there are no numbers in this equation we simply can make an equation for x)

88511, 16351, ?, 10251 missing number in sequence

Mrac [35]

Step-by-step explanation:

this is really complicated and tricky.

to create the next number, you have to add the first 2 digits of the previous number, then subtract the 3rd from the 2nd digit, multiply the 3rd and the 4th digit, and finally divide the 4th digit by the 5th.

so,

8+8 = 16

8-5 = 3

5×1 = 5

1/1 = 1

giving 16351 as next number.

the missing number we get then

1+6 = 7

6-3 = 3

3×5 = 15

5/1 = 5

giving 73155 as the next (missing) number.

control :

7+3 = 10

3-1 = 2

1×5 = 5

5/5 = 1

gives us 10251 as next number - correct.

but then it will end

1+0 = 1

0-2 = -2 ???? take the absolute value ?

2×5 = 10

5/1 = 5

Consider the following statement: The square of a prime number is not prime. (a) Write this as an if-then statement, using caref

Hitman42 [59]

The square of a prime number is not prime.

a) let x ∈ R, If x ∈ {prime numbers}, then $x^{2}$ ∉{prime numbers}

there says that if x is a real and x is in the set of the prime numbers, then the square of x isn't in the set of prime numbers.

b) Prove or disprove the statement.

ok, if x is a prime number, then x only can be divided by himself. Now is easy to see that $x^{2}$ = x*x can be divided by himself and x, then x*x is not a prime number, because can be divided by another number different than himself
