An ant can travel at a constant speed of 980 inches every 5 minutes. At this rate, how far can the ant travel in 7 minutes?
Zarrin [17]

Answer:

1372\: \mathrm{inches}

Step-by-step explanation:

Since the ant travels at a constant speed, we can set up the following proportion:

\frac{980}{5}=\frac{x}{7}, where x is the distance the ant can travel in 7 minutes.

Solving for x, we get:

x=\frac{7\cdot980}{5}=\fbox{$1372\:\mathrm{inches}$}.

The ball's height( in meters above the ground), x seconds after Amir threw it, is modeled by : h(x)=-(x-2)^2 +16 what is the hei
Bess [88]

Answer:

20 m

Step-by-step explanation:

The height of the ball in metres is given as:

h(x) = (x-2)^2 + 16

where xis time, in seconds.

At the instant that the ball is thrown, the time is 0 seconds. This means that the height will be h(0):

h(0) = (0 - 2)^2 + 16\\\\\\h(0) = (-2)^2 + 16\\\\\\h(0) = 4 + 16\\\\\\h(0) = 20 m

The height of the ball is 20 metres.

How do i know if its a linear function and decreasing
nasty-shy [4]

You would know if it is a linear function if it is a line.

The parent function of a linear equation is y = mx + b

If you can find the m which equals slope and the b which is the y-intercept then it is a linear equation.

You would know that it is decreasing by the slope of the equation or by looking at the line on a graph.

If a line is increasing it would go left to right in the positive direction. But in your line, the line is going from right to left which means that it is decreasing. Once you look at a four quadrant graph you would understand that there are negatives and positives.

To find it on a equation, your slope would have to be a negative slope to be decreasing.
