X^2 + 3x - 10 = 0

2x + 3x - 10 = 0

2x + 3x = 5x

5x -10 = 0

+10 +10

5x = 10

5x/5 = 10/5

X = 2


Checking: 2^2 + 3(2) - 10 = 0

4 + 3(2) - 10 = 0

4 + 6 - 10 = 0

10 - 10 = 0

0 = 0

Syyedah throws a baseball with an initial velocity of 30 meters per second from a roof at an initial height of 75 meters. Write
Yuliya22 [10]
Initial velocity: v o = 30 m/s
h = 75 m
h = v o * t + g * t² / 2
75 = 30 · t + 9.8 · t² / 2
75 = 30 t + 4.9 t²
An equation is: y = 4.9 t² + 30 t - 75
4.9 t² + 30 t - 75 = 0
t_{12}= \frac{-30+/- \sqrt{900+1470} }{9.8}= \\  =\frac{-30+48.68}{9.8}
t = 1.9 s

Levart [38]

Answer: 5%

Step-by-step explanation:

Given that:

Ticket price of jacket = $199

Final price after addition of sales tax = $208.95

Percentage sales tax on the jacket =?

Final price after addition of sales tax = price of jacket + amount of sales tax paid

208.95 = 199 + amount of sales tax paid

amount of sales tax paid = 208.95 - 199

amount of sales tax paid = $9.95

Let Percentage of sales tax = x

(x / 100) * 199 = 9.95

199x / 100 = 9.95

199x = 995

x = 5

Hence percent sales tax paid = 5%
