To find the rate, first you divide 180mi/3hr to get 60mph. On the first day they were traveling at a rate of 60mph. It says that on the second day, they drove at the same rate and drove 300 miles. This means you divide 300mi/60mph to get 5hr. They drove 5hr on the second day. And finally, the question asks how long they drove total, so you add 3hr+5hr to get 8hr total.
Answer is 8hr.

The path of a football kicked by a field goal kicker can be modeled by the equation y = –0.03x2 + 1.53x, where x is the horizont
netineya [11]
This is the equation of an upside down parabola, so the maximum height will be at the vertex. To find the vertex, we'll use the formula for the x-coordinate and then solve for the y-coordinate.
x=\frac{-1.53}{2*-.03}=25.5

Plugging this into the given formula:
y=-0.03(25.5)^2+1.53(25.5)=19.5075
Since it asks us to round, the maximum height would be 20 yards. To find how far the football travels in total, we need to set the equation equal to 0 and find the roots:
0=-0.03x^2+1.53x=x(-0.03x+1.53)

Then by the zero product property (or the no zero divisors rule), we have:
x=0 (this is the x value where the ball is kicked from)
-0.03x+1.53=0
-0.03x=-1.53
x=51

So the ball travels 51 yards in total.

State the slope and the y-intercept for the graph of each equation y= -3/7x–1/7
MaRussiya [10]

Answer: Y-intercept is (0,-1/7) and the slope is -3/7

Step-by-step explanation:

State the slope and the y-intercept for the graph of each

equation y= -3/7x–1/7

To find the y-intercept,

you plug in 0 in for x for y= -3/7x–1/7

y=-3/7(0)-1/7

y=0-1/7

y=-1/7

The y-intercept is (0,-1/7)

To find the slope, you first check that the equation is in the form of y=mx+b

y= -3/7x–1/7 is in the from of y=mx +b.

The m is the slope

hence, in y= -3/7x–1/7 the slope is -3/7
