The maximum of this parabola is (3/4,16).
Therefore since time is on the x-axis, the ball reaches the maximum height at 3/4secs.
And since the height is on the y-axis, the ball will each a maximum height of 16ft.

In ΔKLM, m = 160 cm, ∠M=145° and ∠K=28°. Find the length of l, to the nearest 10th of a centimeter.
Montano1993 [528]

Answer:

34.0 m

Step-by-step explanation:

The total angle sum in a triangle should be 180° hence the missing angle will be given by

180°-145°-28°=7°

Using sine rule

\frac {m}{sin M}=\frac {l}{sin L}=\frac {k}{sin K}

By substituting 160 for m, 145° for M and 7° for L then

\frac {160}{sin 145^{\circ}}=\frac {l}{sin 7^{\circ}}

Making l the subject then

l=\frac {160 sin 7^{\circ}}{sin 145^{\circ}}=33.9956345990643m\\l\approx 34.0m

The sum of a number and 72 times its reciprocal is -17. Find the number
butalik [34]
Let, the number = x

Then, x + 72/x = -17

x² + 72 = -17x

x² + 17x + 72 = 0

x² + 8x + 9x + 72 = 0

x(x + 8) 9(x + 8) = 0

(x + 8)(x + 9) = 0

x = -8 OR -9

In short, Your Number would be: Either -9 or -8

Hope this helps!
