The option first is correct because y= 2√x and y= √2x have same domain which is x ≥ 0.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

y= 2√x

From the above function the domain should be:

x ≥ 0 (because square root of negative values does not exist)

The function:

y = √(2x)

2x ≥ 0

x ≥ 0

Thus, the option first is correct because y= 2√x and y= √2x have same domain which is x ≥ 0.

What is 70/360 in percentage

defon

Answer:

About 19.45%

Step-by-step explanation:

First set the fraction equal to x over 100 ———- (70/360)=(x/100)

cross multiply———- 70 * 100 = 7000 360 * x = 360x

solve for x —————- 7000=360x

7000/360= 19.44444444

Round ——- x=19.45

Divide fraction ———— 70/360 = 0.1944444444

Next, convert to percentage by moving decimal 2 places to the right ——

019.44444444

Round ————- = 19.45

calculate the distance between the two points shown on the graph below give your answer correct to 2 decimal places if necessary

GenaCL600 [577]

Answer:

Find the distance between (-1, 1) and (3, 4).

This problem is solved simply by plugging our x- and y-values into the distance formula:

D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=

=16+9−−−−−√=25−−√=5

Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.

If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:

(x1+x22,y1+y22)

Mr. Jones sold two pipes at $1.20 each. Based on the cost, his profit was 20% and his loss on the other was 20%. On the sale of

madam [21]

Answer:

Selling price of the first pipe = $1.20

Profit = 20%

Let’s try to find the cost price of the first pipe

CP = Selling price - Profit

CP = 1.20 - 20% of CP

CP = 1.20 - 0.20CP

CP + 0.20CP = 1.20

1.20CP = 1.20

CP = 1.201.20

CP = $ 1

Selling price of the Second pipe = $1.20

Loss = 20%

Let’s try to find the cost price of the second pipe

CP = Selling price + Loss

CP = 1.20 + 20% of CP

CP = 1.20 + 0.20CP

CP - 0.20CP = 1.20

0.80CP = 1.20

CP = 1.200.80

CP = $1.50

Therefore, total cost price of the two pipes = $1.00 + $1.50 = $2.50

And total selling price of the two pipes = $1.20 + $1.20 = $2.40

Loss = $2.50 – $2.40 = $0.10

Therefore, Mr. Jones loss 10 cents.

i know that this is hard to understand so tell me if you need help

Have a great day :)

A piece of cloth is folded into a square with a side length measuring x inches. When it is unfolded, it has an area of x2 + 27x

IgorC [24]

A piece of cloth is folded into a square with a side length measuring x inches. When it is unfolded, it has an area of x2 + 27x + 162 square inches. Since the area for square is x times x then equate the given equation to the area fomula.
(x2 + 27x + 162) = 0(x + 9) (x + 18) = 0The dimensions are 9 and 18

The number of nickels that Milad has is twelve more than the number of dimes that miss o has. If they both have the same amount

Ostrovityanka [42]

So n=number of nickles
d=number of dimes
n is 12 more than d so
n=12+d
but they have same amount of money so
n times 5=worth of nickles
d times 10=worth of dimes
5n=10d
divide both sides by 5
n=2d
subsitute
n=2d
n=12+d
2d=n=12+d
2d=12+d
subtract d from both sides
d=12
subsitute
n=12+d
n=12+12
n=24

24 nickles
12 dimes
