____ [38]

Answer: It will not be spread out horizontally across the entire coordinate plane because in Step 2, Jacob plotted Fahrenheit instead of Celsius on the x-axis.

Jacob confused the values, the first coordinate of the ordered pairs (which corresponds to the x-axis) is in Celsius and he used it as Farenheit.

A student had 500 milliliters of water in a water bottle. She drank 25% of the water before soccer practice. After practice, she drank 1/3 of the remaining water.

How much water, in milliliters, does the student have left in the bottle?

Answer:

the amount of water the student have left in the bottle is 250 milliliters

Step-by-step explanation:

A student had 500 milliliters of water in a water bottle. She drank 25% of the water before soccer practice. After practice, she drank 1/3 of the remaining water.

How much water, in milliliters, does the student have left in the bottle?

Before the soccer practice, she drank 25 % of the water

25% of the water = 25% of 500

= 25% × 500

= $\frac{25}{100}$ × 500

At the right hand-side of the equation, the two zeros will cancel-out the other two zeros, hence;

= 25 × 5

=125

25% of the water = 125 milliliters

From the question, it was said that drank 25% of the water before soccer, this implies that she drank 125 milliliters from the water bottles.

If she drank 125 milliliters of from a 500 milliliters water contain in the water bottle, then the amount of water left will be 500 ml - 125 ml = 375 ml

This implies that before the soccer practice she had 375 milliliters of water left in the water bottle.

After the practice, she drank 1/3 of the remaining water, which means after the practice she drank 1/3 of 375

1/3 of 375 = $\frac{1}{3}$ × 375 = $\frac{375}{3}$ = 125

After the practice she drank 125 milliliters of water from her 375 milliliters water.

The amount of water she have left after the practice will be;

375 milliliters - 125 milliliters = 250 milliliters

Therefore, the amount of water the student have left in the bottle is 250 milliliters

Find the real solutions of the equation by graphing

Vlada [557]

Answer:

C. 0, 1.29, -0.65

Step-by-step explanation:

The real solutions of the equation $19x^3-12x^2-16x=0$ is where the graph of $y=19x^3-12x^2-16x$ intersects the x-axis.

This means that we need to graph $y=19x^3-12x^2-16x$ using a graphing software.

From the graph shown in the attachment $x=0$ , $x=1.29$ , and $x=-0.65$ are the real solutions.

The correct choice is C
