(9.8)(6)= 1/2 v^2

解答

(9.8) (6) = \frac{1}{2} v^{2}

解答

v = \frac{14 3}{5}, v = - \frac{14 3}{5}

+1

十进制

v = 10.84435 \dots, v = - 10.84435 \dots

求解步骤

(9.8) (6) = \frac{1}{2} v^{2}

交换两边

\frac{1}{2} v^{2} = (9.8) (6)

去除括号:

(a) = a

\frac{1}{2} v^{2} = 9.8 \cdot 6

数字相乘:

9.8 \cdot 6 = 58.8

\frac{1}{2} v^{2} = 58.8

在两边乘以

2

v^{2} = 117.6

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

v = 117.6, v = - 117.6

117.6 = \frac{14 3}{5}

- 117.6 = - \frac{14 3}{5}

v = \frac{14 3}{5}, v = - \frac{14 3}{5}

30 (25 - t^{2}) = 450

x^{2} - 15 x + 4 = 0

m^{2} + 8 = 0

(x-2)^2+3(x+4)(x-4)=2(x+3)(x-1)

(x - 2)^{2} + 3 (x + 4) (x - 4) = 2 (x + 3) (x - 1)

9^{2} = 7^{2} + b^{2}
