Answer:

I will first divide the figure into two which gives me a rectangle and a semi circle

area of figure = area of rectangle + area of semi circle

= [(length × width)+(1/2πr²)]

[(10×15)+(1/2×22/7×5×5)]

[(150)+(39.29)]

= 189.3cm²

Whats the slope intercept form for the points [5,2] and [0,-1]

Advocard [28]

Answer:

$\displaystyle y=\frac{3}{5}x-1$

Step-by-step explanation:

<u>The Equation of a Line</u>

The equation of the line in slope-intercept form is:

$y=mx+b$

Where m is the slope and b the y-intercept.

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

We are given the points (5,2) and (0,-1), thus:

$\displaystyle y-2=\frac{-1-2}{0-5}(x-5)$

Operating:

$\displaystyle y-2=\frac{-3}{-5}(x-5)$

$\displaystyle y-2=\frac{3}{5}(x-5)$

To find the slope-intercept form, we continue to simplify the expression:

Removing the parentheses:

$\displaystyle y-2=\frac{3}{5}x-\frac{3}{5}\cdot 5$

$\displaystyle y-2=\frac{3}{5}x-3$

Adding 2:

$\displaystyle y=\frac{3}{5}x-3+2$

$\mathbf{\displaystyle y=\frac{3}{5}x-1}$

Describe how the cosecant, secant and cotangent are related to the first three trigonometric functions learned.

$\bf \underline{sin(\theta)}=\cfrac{1}{csc(\theta)}
\qquad 
% cosine
\underline{cos(\theta)}=\cfrac{1}{sec(\theta)}
\qquad 
% tangent
tan(\theta)=\cfrac{sin(\theta)}{cos(\theta)}
\\\\\\
% cotangent
csc(\theta)=\cfrac{1}{\underline{sin(\theta)}}
\qquad 
% secant

Find the percentage change from 50 to 82. Indicate whether it is an increase or a decrease. If necessary, round your answer to t

Dmitrij [34]

Percentage change from 50 to 82, first, let's solve how much is added from 50 to 82.
=> 82 - 50 = 32
Now how many percent is 32 out of 50?
=> 32 / 50 = 0.64
=> 0.64 * 100% = 64%
thus 64% added or increased in the previous number.
