Answer:

178.5 m^2

Step-by-step explanation:

Here we see a square and a half circle

Equation: A=bh+πr²

Square: 10*10= 100

Half circle: π5² (it is 5 because the diameter is 10)

A= 25π

A=100+25π

A=178.5

What are the coordinates of the point on the directed line segment from (−6,8) to (6,−7) that partitions the segment into a rati

Maslowich

Answer:

(2, -2)

Step-by-step explanation:

The difference of coordinates is ...

(6, -7) -(-6, 8) = (12, -15)

The point of interest is located 2/(2+1) = 2/3 of this distance from the first point. So, the point of interest is ...

first point + 2/3 distance

= (-6, 8) + (2/3)(12, -15)

= (-6, 8) + (8, -10)

= (2, -2)

_____

In symbolic terms, the point P that is 2/3 of the distance from A to B is ...

P = A + (2/3)(B -A) = (1/3)A +(2/3)B

P = (A +2B)/3

Filling in the coordinate values, we find ...

P = ((-6, 8) +2(6, -7))/3 = (-6+12, 8-14)/3 = (6, -6)/3

P = (2, -2)

Pls help, I've been stuck on this for a week

Answer:

$\sin(C)=\pm\sqrt{1-\cos^2(C)}$

Step-by-step explanation:

Given the Pythagorean Identity:

$\sin^2(C)+\cos^2(C)=1\\$

We want to solve for sin(C).

First, we will subtract cos²(C) from both sides:

$\sin^2(C)=1-\cos^2(C)$

Next, we will take the square root of both sides. Since we are taking an even-root, we will need to add plus/minus. Hence:

$\sin(C)=\pm\sqrt{1-\cos^2(C)}$
