Can someone help me with this and tell me the steps too

Answer:

B. 2.2

Step-by-step explanation:

Volume of a rectangular prism = length*width*height

You can replace the width with the variable x for now, the height is given in the problem, and the length is 4 times the width so in this case it's 4x.

160 = 4x*x*8

160 = 32x^2

5 = x^2

The square root of five is about 2.2 so B is the correct answer

Find f' f(x)=sqr root(x+9), a=7 use the definition lim f(x+h)-f(x)/h

Romashka-Z-Leto [24]

f(x)=√(x+9)

f(x+h) =√(x+h+9)

$f'(x) = \lim_{h \to \\0} \frac{\sqrt{x+9+h}-\sqrt{x+9}}{h} = \\ \\ = \lim_{h \to \\0} \frac{(\sqrt{x+9+h}-\sqrt{x+9})*(\sqrt{x+9+h}+\sqrt{x+9})}{h(\sqrt{x+9+h}+\sqrt{x+9})} = \\ \\= \lim_{h \to \\0} \frac{(\sqrt{x+9+h})^{2}-(\sqrt{x+9})^{2}}{h(\sqrt{x+9+h}+\sqrt{x+9})}= \\ \\= \lim_{n \to \\0} \frac{x+9+h-x-9}{h(\sqrt{x+9+h}+\sqrt{x+9})}=\lim_{n \to \\0} \frac{h}{h(\sqrt{x+9+h}+\sqrt{x+9})}=\lim_{n \to \\0} \frac{1}{(\sqrt{x+9+h}+\sqrt{x+9})} = \\ \\= \frac{1}{(\sqrt{x+9+0}+\sqrt{x+9})} =$

$=\frac{1}{(\sqrt{x+9}+\sqrt{x+9})} = \frac{1}{2\sqrt{x+9}}$

$f'(x)= \frac{1}{2\sqrt{x+9}} \\ \\ f'(a)=\frac{1}{2\sqrt{a+9}} \\ \\a=7 \\ \\f'(7)= \frac{1}{2\sqrt{7+9}} = \frac{1}{2*4} =\frac{1}{8} \\ \\f'(7)= \frac{1}{8}$

8i-(12-4i)+7√-9 show work please

Tanya [424]

Answer:

33i - 12

Step-by-step explanation:

$8i - (12 - 4i) + 7 \sqrt{ - 9} \\ = 8i - 12 + 4i + 7 \sqrt{9 \times ( - 1)} \\ = 12i - 12 + 7 \times 3 \sqrt{ - 1} \\ = 12i - 12 + 21i \: \: ( \because \sqrt{ - 1} = i)\\ = 12i + 21i - 12 \\ \therefore \red{ \bold{8i - (12 - 4i) + 7 \sqrt{ - 9} }= \purple{ \bold{33i - 12}}}$
