The answer of -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] is 0.06237948089

Step-by-step explanation:

To solve this problem -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] we must start with

1. Solve this bracket [9 (-8.9 + 9/5) .01] at first

2. Multiply the answer of the bracket by 66.9

3. Multiply -3(8/9) and divide the answer by the product of the previous

step

In [9 (-8.9 + 9/5) .01]

∵ (-8.9 + 9/5) = (-8.9 + 1.8) = -7.1

∴ [9 (-8.9 + 9/5) .01] = [9 (-7.1).01]

∵ 9(-7.1)(.01) = -0.639

∴ [9 (-8.9 + 9/5) .01] = -0.639

∵ 66.9 [-0.639] = -42.7491

∵ $-3(\frac{8}{9})=\frac{-8}{3}$

∴ -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] = $\frac{-8}{3}$ ÷ -42.7491

∴ -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] = 0.06237948089

The answer of -3(8/9) ÷ 66.9[9 (-8.9 + 9/5) .01] is 0.06237948089

Ex 4.8<br> 14) integrate 3^(2x-1)

sesenic [268]

Take the integral:

$\large\begin{array}{l} \mathsf{\displaystyle\int\!3^{2x-1}\,dx}\\\\ =\mathsf{\displaystyle\int\!\frac{1}{2}\cdot 2\cdot 3^{2x-1}\,dx}\\\\ =\mathsf{\displaystyle\frac{1}{2}\int\!3^{2x-1}\cdot 2\,dx\qquad(i)} \end{array}$

$\large\begin{array}{l} \textsf{Substitute}\\\\ \mathsf{2x-1=u\quad\Rightarrow\quad 2\,dx=du}\\\\\\ \textsf{so (i) becomes}\\\\ =\mathsf{\displaystyle\frac{1}{2}\int\!3^u\,du}\\\\ =\mathsf{\dfrac{1}{2}\cdot \dfrac{1}{\ell n\,3}\,3^u+C}\\\\ =\mathsf{\dfrac{1}{2\,\ell n\,3}\,3^{2x-1}+C} \end{array}$

$\large\begin{array}{l} \boxed{\begin{array}{c}\mathsf{\displaystyle\int\!3^{2x-1}\,dx=\frac{1}{2\,\ell n\,3}\,3^{2x-1}+C} \end{array}}\qquad\checkmark \end{array}$

Answer:

Step-by-step explanation:

$- 1 | \frac{2}{3} - 4| \div \frac{5}{6} \\ - 1 | \frac{2}{3} - \frac{4 \times 3}{1 \times 3} | \div \frac{5}{6} \\ - 1 | \frac{2 - 12}{3} | \div \frac{5}{6} \\ - 1 | \frac{ - 10}{3} | \div \frac{5}{6} \\ \frac{10}{3} \div \frac{5}{6} \\ \frac{10}{3} \times \frac{6}{5} \\ \frac{2}{1} \times \frac{2}{1} = 4$
