Answer:

n = 3

Step-by-step explanation:

I guess you want the value of n

-----------------------------------------------------------

Since n is the index of q, you can simply

ignore all p and r stuff and make it

$q^{2}$ × $q^{n}$ = $q^{5}$

$q^{2+n}$ = $q^{5}$

2 + n = 5

n = 3

A boy is playing a ball in a garden surrounded by a wall 2.5 m high and kicks the ball vertically up from a height of 0.4 m with

kow [346]

Answer:

2.5 sec

Step-by-step explanation:

Height of wall = 2.5 m

initial speed of ball = 14 m/s

height from which ball is kicked = 0.4 m

we calculate the speed of the ball at the height that matches the wall first

height that matches wall = 2.5 - 0.4 = 2.1 m

using = + 2as

where a = acceleration due to gravity = -9.81 m/s^2 (negative in upwards movement)

= + 2(-9.81 x 2.1)

= 196 - 41.202

= 154.8

v = = 12.44 m/s

this is the velocity of the ball at exactly the point where the wall ends.

At the maximum height, the speed of the ball becomes zero

therefore,

u = 12.44 m/s

v = 0 m/s

a = -9.81 m/s^2

t = ?

using V = U + at

0 = 12.44 - 9.81t

-12.44 = -9.81

t = -12.44/-9.81

t = 1.27 s

the maximum height the ball reaches will be gotten with

= + 2as

a = -9.81 m/s^2

0 = + 2(-9.81s)

0 = 196 - 19.62s

s = -196/-19.62 = 9.99 m. This the maximum height reached by the ball.

height from maximum height to height of ball = 9.99 - 2.5 = 7.49 m

we calculate for the time taken for the ball to travel down this height

a = 9.81 m/s^2 (positive in downwards movement)

u = 0

s = 7.49 m

using s = ut + a

7.49 = (0 x t) + (9.81 x )

7.49 = 0 + 4.9

= 7.49/4.9 = 1.53

t = = 1.23 sec

Total time spent above wall = 1.27 s + 1.23 s = 2.5 sec

A Campus Republicans fundraiser offers raffle tickets for $10 each. The prize for the raffle is a $425 television set, which mu

Anon25 [30]

Answer:

The profit equation would be: Profit = 10t - 425. To break even, 43 tickets must be sold, rounded up to the nearest whole number.

Step-by-step explanation:

Tickets = 10 * t, or $10 dollars per ticket

Prize = $425

Profit = (10 * t) - 425

Break-even is when the Function value would be Zero. This can be found by dividing the dollar amount by 10 to get 42.5 tickets or 43 tickets. After 43 tickets sold, the rest is profit.

The equation would be:

Profit = 10t - 425

A negative value would represent a net loss.

SEE BELOW PLEASE GIVE BRAINLIEST

Step-by-step explanation:

YEAR 1: 40000 X .03 = 1200 40,000 + 1200 = 41200

YEAR 2: 41,200 X .03 = 1236 41,200 + 1236 = 42436

YEAR 3: 42436 X .03 = 1273.08 42436 + 1273.08 = 43709.08

YEAR 4: 43709.08 x .03 = 1311.27 43709.08 + 1311.27 = 45020.35

YEAR 5: 45020.35 X .03 = 1350.61 45020.35 + 1350.61 = 46370.96

YEAR 6: 46370.96 X .03 = 1391.13 46370.96 + 1391.13 = 47762.09

YEAR 7: 47762.09 X .03 = 1432.86 47762.09 + 1432.86 = 49194.95

YEAR 8: 49194.95 X .03 = 1475.85 49194.95 + 1475.85 = 50670.80

YEAR 9: 50670.80 X .03 = 1520.12 50670.80 + 1520.12 = 52190.92

YEAR 10: 52190.92 X .03 = 1565.73 52190.92 + 1565.73 = 53756.65

YEAR 11: 53756.65 X .03 = 1612.70 53756.65 + 1612.70 = 55369.35

YEAR 12: 55369.35 X .03 = 1661.08 55369.35 + 1661.08 = 57030.43

YEAR 13: 57030.43 X .03 = 1710.91 57030.43 + 1710.91 = 58741.34

YEAR 14: 58741.34 X .03 = 1762.24 58741.34 + 1762.24 = 60503.58

YEAR 15: 60503.58 X .03 = 1815.11 60503.58 + 1815.11 = 62318.69

YEAR 16: 62318.69 X .03 = 1869.56 62318.69 + 1869.56 = $64,188.25 = $64188
