vagabundo [1.1K]

The phrases that fit the graph of y = \sqrt x are

  • curve            positive x-values
  • point (1, 1)        x-intercept = 0
  • quadrant I           y-intercept = 0

<h3>How to select the phrases</h3>

The equation of the function is given as:

y = \sqrt x

Next, we plot the graph of the function (see attachment)

From the attached graph, we have the following highlights:

  • All points are in quadrant I
  • The function is a curve
  • It has an x-intercept of x = 0
  • It has a y-intercept of y = 0
  • It has only positive x values
  • It passes through (1,1)

The above represents the phrases that fit the graph

Can yall help my friend plzz
GarryVolchara [31]

Step-by-step explanation:

The Pythagorean theorem used in right-angled (equilateral) triangles is a relationship between the sides of a right-angled triangle, where the sum of the square of the legs is equal to the square of the hypotenuse.

If a and b are legs, and c is the hypotenuse, then a2 + b2 = c2.

Because the triangle is right angled, there is no greater side length in the triangle, so an unlimited number of Pythagorean positions can be produced by flipping the sides.

allochka39001 [22]

Answer:

18 gallons

Step-by-step explanation:

Step one:

given data

The gas in Dad's car holds 12 gallons

the gas tank in Moms truck holds 50% more than that in Dad's car

Hence 50% of 12 is

=50/100*12

=0.5*12

= 6 gallons

We are told that the gas tank in Moms truck holds 50% more than that in Dad's car

Therefore Mum's car will hold

=12+6

=18 gallons
