solvefor d,0=(14 m/s)^2+2(-9.8 m/(s^2))d

解答

求解

d, 0 = (14 \frac{m}{s})^{2} + 2 (- 9.8 \frac{m}{s ^{2}}) d

解答

d = 10 m; s \neq = 0, m \neq = 0

求解步骤

0 = (14 \cdot \frac{m}{s})^{2} + 2 (- 9.8 \cdot \frac{m}{s ^{2}}) d

交换两边

(14 \cdot \frac{m}{s})^{2} + 2 (- 9.8 \cdot \frac{m}{s ^{2}}) d = 0

化简

(14 \cdot \frac{m}{s})^{2} + 2 (- 9.8 \cdot \frac{m}{s ^{2}}) d : \frac{196 m ^{2}}{s ^{2}} - \frac{19.6 m d}{s ^{2}}

\frac{196 m ^{2}}{s ^{2}} - \frac{19.6 m d}{s ^{2}} = 0

将

\frac{196 m ^{2}}{s ^{2}}

到右边

- \frac{19.6 m d}{s ^{2}} = - \frac{196 m ^{2}}{s ^{2}}

在两边乘以

s^{2}

- 19.6 m d = - 196 m^{2}; s \neq = 0

两边除以

- 19.6 m; s \neq = 0, m \neq = 0

d = 10 m; s \neq = 0, m \neq = 0

solvefor x,y-(-3)=-5/8 (x-2)

so l v e f or x, y - (- 3) = - \frac{5}{8} (x - 2)

solvefor a,5a+3b=540

so l v e f or a, 5 a + 3 b = 540

solvefor x,f(x+1)=2x-4

so l v e f or x, f (x + 1) = 2 x - 4

bn = 7 \cdot 5^{- n}

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

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