Suppose the integral from 2 to 8 of g of x, dx equals 12, and the integral from 6 to 8 of g of x, dx equals negative 3, find the
Artyom0805 [142]

\displaystyle\int_2^8g(x)\,\mathrm dx=12

\displaystyle\int_6^8g(x)\,\mathrm dx=-3

Use the fact that integrals are additive on their intervals. Mathematically, if c\in[a,b], then

\displaystyle\int_a^bg(x)\,\mathrm dx=\int_a^cg(x)\,\mathrm dx+\int_c^bg(x)\,\mathrm dx

So we have

\displaystyle2\int_2^6g(x)\,\mathrm dx=2\left(\int_2^8g(x)\,\mathrm dx-\int_6^8g(x)\,\mathrm dx\right)=2(12-(-3))=30

The angle of elevation of the sun is 24°. What is the length of the shadow cast by a person 1.82 m tall?
amm1812

Answer:

4.09 m

Step-by-step explanation:

Let the length of the shadow cast by a person be x m.

\tan \: 24 \degree =  \frac{height \: of \: person}{length \: of \: the \: shadow}  \\  \\ 0.4452286853 =  \frac{1.82}{x}  \\  \\ x =  \frac{1.82}{0.4452286853}  \\  \\ x = 4.08778693 \: m \\ x = 4.09 \: m

Use the following work shown below to answer the following question.​
zysi [14]

Answer:

\frac{3 + \sqrt{3x} }{3 - x}

Step-by-step explanation:

You can use the work they gave you and continue from there:

\frac{\sqrt{3}(\sqrt{3}) + \sqrt{3}(\sqrt{x})  }{(\sqrt{3}) ^{2} - (\sqrt{x} )^{2} }

First, simplify the numerator:

\frac{3 + \sqrt{3x} }{(\sqrt{3}) ^{2} - (\sqrt{x}) ^{2} }

Finally, simplify the denominator:

\frac{3 + \sqrt{3x} }{3 - x}
