Answer:

1. Ice melts under heat and temperatures above freezing point.

2. If I leave my ice underneath the sun, then it will melt.

3. I would test it by putting ice into a bowl and leave it outside for five minutes.

4. After five minutes, I would go outside and see what percentage of the ice has melted.

5. Ice melts underneath high temperatures and the higher the temperature, the faster the ice melts.

Problem 2.9 a runner completes the 200-meter dash with a time of 20.19 seconds. part a what was the runner's average speed in me

Elina [12.6K]

Answer:

Average speed = 9.91 m/s

Explanation :

Total distance covered by a runner = 200 m

Time taken to complete this distance = 20.19 sec

We need to find the average of runner speed in meter/sec

We use the speed, distance, time formula

$speed = \frac{distance}{time}$

speed = $\frac{200}{20.19}$

Average speed = 9.91 m/s

that's the final answer.

I hope it will help you.

What is the vertex of g(x) = –3x2 + 18x + 2?

blsea [12.9K]

Answer:

$(3,29)$

Step-by-step explanation:

There is a formula that can be used to find the x-value of the vertex of the parabola. This formula is $x=\frac{-b}{2a}$

We have the function $g(x)=-3x^2+18x+2$

From this function, we can find that

$a=-3\\b=18\\c=2$

We can plug in our know values into the formula to get

$x=\frac{-18}{2(-3)\\} \\x=\frac{-18}{-6} \\\\x=3$

Then we can plug in our x-value to find the y-value of the vertex

$g(3)=-3(3)^2+18(3)+2\\\\g(3)=-3(9)+54+2\\\\g(3)=-27+54+2\\\\g(3)=29$

This means that the vertex would be $(3,29)$
