What is the value of x?

Answers

Answer:

x = 7 cm

Step-by-step explanation:

The two triangles are similar so ...

x/(6 cm) = (42 cm)/(36 cm)

Multiplying by 6 cm, you get ...

x = (6 cm)(42 cm)/(36 cm) = (6 cm)(7/6)

x = 7 cm

A softball thrown into the air has a parabolic trajectory. After reaching a maximum height of 28 feet, the ball covers a ground distance of 4 feet before hitting the ground. Which equation describes the ball’s trajectory?

Answers

If the take the origin as the starting point of the ball, then the vertex would be (4,28) and the parabola would be facing downwards. Using the general form of the parabola which is (x-h)^2 = 4p(y-k) where h and k are taken from the coordinate of the vertex (h,k).
So, the equation would be, (x-4)^2)=4p(y-28). To determine 4p, we can substitute either of the two points: (0,0) or (0,8). The second coordinate is taken from the given that the ball covers a distance of 4 ft after it reaches a maximum height. The total distance traveled by the ball is twice that, which is 8 ft.
After substituting, 4p = -4/7. Plugging this into the equation and after expanding and simplifying, the equation of the ball's trajectory is:
y = (-4/7)x^2+14x

What is the solution to the system of equations? Use the linear combination method.2d+e=8
d-e-4

A. There are an infinite number of solutions
B. There is no solution
C. The solution is (4,0)
D. The solution is (5,-2)

Answers

If you would like to know what is the solution to the system of equations, you can calculate this using the following steps:

2d + e = 8
d - e - 4 = 0 ... d = e + 4
___________________

2d + e = 8
2 * (e + 4) + e = 8
2e + 8 + e = 8
3e = 0
e = 0

d = e + 4 = 0 + 4 = 4

(d, e) = (4, 0)

The correct result would be: C. The solution is (4, 0).
