<em><u>Answer:</u></em>
<em><u>y = 5, 3; x = 171, 155</u></em>
<em><u>Step-by-step explanation:</u></em>
8y - 15 = y^2
y^2-8y+15=0
y^2-3y-5y+15=0
y(y-3)-5(y-3)=0
(y-5)(y-3)=0
y can be 5 or 3.
x = 180 - (8y - 15)
x = 180 - (8(3)-15)
x = 180 - 9
x = 171
OR
x = 180 - (8(5) - 15)
x = 180 - 25
x = 155
Answer:
B
Step-by-step explanation:
you put the equation into the calculator and put the other ones into the calculator and see which one matches
If this is a parabolic motion equation, then it is a negative parabola, which looks like a hill (instead of a positive parabola that opens like a cup). Your equation would be h(t)= -16t^2 + 20t +3. That's the equation for an initial velocity of 20 ft/s thrown from an initial height of 3 ft. And the -16t^2 is the antiderivative of the gravitational pull. Anyway, if you're looking for the maximum height and you don't know calculus, then you have to complete the square to get this into vertex form. The vertex will be the highest point on the graph, which is consequently also the max height of the ball. When you do this, you get a vertex of (5/8, 9.25). The 9.25 is the max height of the ball.
Answer:
A.) 1350 miles
Step-by-step explanation:
So, you know the amount of 1/2 of an in. is equal to 200 miles on the map. Next, you have to change the 1/2 to be a common denominator, so you change it to 4/8. Now, you have 4/8=200 mi. Okay, so, to get your answer, you divide the equation here __^^^ by 4 to get 1/8=50 miles. Then, you turn 3 and 3/8 into an improper fraction, which is 27/8, and do 50 times 27 to get 1350 miles.
