Solve for x. 0.71= 1/2(9.8) x^2.

Fudgin [204]

Answer: 0.38065

in simpler terms x=± 0.145 =±0.38065

Step-by-step explanation: -490x2+71 = 0

Subtract 71 from both sides of the equation :

-490x2 = -71

Multiply both sides of the equation by (-1) : 490x2 = 71

Divide both sides of the equation by 490:

x2 = 71/490 = 0.145

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:

x = ± √ 71/490

The equation has two real solutions

These solutions are x = ±√ 0.145 = ± 0.38065

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-5, -7)

Point (-4, 1)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [SF]: $\displaystyle m=\frac{1+7}{-4+5}$
[Fraction] Add: $\displaystyle m=\frac{8}{1}$
[Fraction] Divide: $\displaystyle m=8$
