Find the area of the trapezoid

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

Formula

$\frac{1}{2} \times h \times (sum \: of \: parallel \: sides(b1 + b2))$

Your scale is 2cm to 2units therefore the parameters are as follows

h=4

b1=9

b2=13

$\frac{1}{2} \times 4 \times (9 + 13)$

$\frac{1}{2} \times 4 \times 22$

$\frac{1}{2} \times 88$

$\frac{88}{2} \\ = 44$

Solve in attachment....

Answer:

A)2

Step-by-step explanation:

we would like to integrate the following definite Integral:

$\displaystyle \int_{0} ^{1} 5x \sqrt{x} dx$

use constant integration rule which yields:

$\displaystyle 5\int_{0} ^{1} x \sqrt{x} dx$

notice that we can rewrite √x using Law of exponent therefore we obtain:

$\displaystyle 5\int_{0} ^{1} x \cdot {x}^{1/2} dx$

once again use law of exponent which yields:

$\displaystyle 5\int_{0} ^{1} {x}^{ \frac{3}{2} } dx$

use exponent integration rule which yields;

$\displaystyle 5 \left( \frac{{x}^{ \frac{3}{2} + 1 } }{ \frac{3}{2} + 1} \right) \bigg| _{0} ^{1}$

simplify which yields:

$\displaystyle 2 {x}^{2} \sqrt{x} \bigg| _{0} ^{1}$

recall fundamental theorem:

$\displaystyle 2 ( {1}^{2}) (\sqrt{1} ) - 2( {0}^{2} )( \sqrt{0)}$

simplify:

$\displaystyle 2$

hence

our answer is A
