Answer:

#4 = 9m

#3 = 50.135 m

Step-by-step explanation:

for number 4 all you have to do is find the area of the whole figure and then subtract the area of that square inside it so 5 x 2 = 10     10 - 1 x 1 = 9

#3 first find the square to be 36 m then find the half circle

diameter = 6 so radius = 3

a = pie x 3^2 so a = 28.27 but its a half circle so 28.27/2 = 14.135 then add 36 to it so 50.135

choose the equation in point slope form for the line that is perpendicular to the given line and passing through the given point
alexdok [17]

We want to determine the equation in point slope form for the line that is perpendicular to the given line and passing through the point (5.6) .

The equation and the point is;

y=\frac{2}{3}x+9,(5,6)

We know that for two lines to be perpendicular, the product of their slopes should be -1.

Therefore, the slope of the perpendicular should be;

m=-\frac{1}{(\frac{2}{3})}=-\frac{3}{2}

The second condition is that the line must pass through the point (5,6) , to do thid, we write the equation of the line in point slope form which is;

y-y_1=m(x-x_{1_{}})

Inserting all values, we have,

y-6=.-\frac{3}{2}(x-5)

That is the final answer.
