HELP ASAP//BRAINLEST+THANKS: Subj:gravity formula stuff
Y_Kistochka [10]

Answer:

6.46

Step-by-step explanation:

h(t) = (1/2)att^{2} + v0t + h0

Origin is at surface of water (h = 0), up is positive.

a = -g = -9.8 m/s^{2}

v0 = 25 m/s

h0 = 50 m

h(t) = -4.9t2 + 25t + 50

Find t when

7 = -4.9t^{2} + 25t + 50

4.9t^{2} - 25t - 43 = 0

t = [1/(2*4.9)] [25 ±√(25^{2} + 4*4.9*43)]

t = (0.102)(25 ± 38.312)

t > 0 ⇒ use only the positive square root

t = (0.102)(25 + 38.312) ≅ 6.46 s

It is 7m above the water at about 6.46 s

The measures of the first and second angles in a triangle are equal.The third angle measures 9 times the sum of the equal angles
Liula [17]

9514 1404 393

Answer:

  9°, 9°, 162°

Step-by-step explanation:

Let x represent the measure of the first angle. Then the sum of all of the angles in the triangle is ...

  x + x + 9(x+x) = 180°

  20x = 180° . . . . . . . . . . collect terms

  x = 180°/20 = 9° . . . . . divide by 20

  9(x+x) = 162° . . . . . . . find the third angle

The three angle measures are 9°, 9°, and 162°.

30 minutes is 1/2 an hour.

60 minutes is a full hour.

Monday thru Saturday is:

Monday, Tuesday, Wednesday, Thursday. Friday, Saturday. That is 6 days total.

30 minutes a day for 6 days is 180 minutes.

180 minutes / 60 minutes = 3 hours.

3 hours x $7 = $21
