SUPER CONFUSED! EXPLAIN PLS! EMERGANCY!

Answers

Answer:

73.12m²

Step-by-step explanation:

Okay, you can break this figure into a half-circle and a triangle, we're going to start with the triangle (using the handy formula sheet you have up there)

12 x 8 = 96

96 x ½ = 48

Now we do the semicircle (the formula for a circle is pi x radius² )

the radius is half of the diameter so:

8 ÷ 2 = 4

4² = 16

we're using 3.14 for pi so:

3.14 x 16 = 50.24

Now we'd normally stop there, but this is only a semicircle, so we have to chop it in half again:

50.24 ÷ 2 = 25.12

Now we add both of those together:

48 + 25.12 = 73.12‬

So the area of the figure is 73.12m²

hope this helps:)

The graphs of linear functions fand g are shown on the grid.
which function best represented by the graph of g

Answers

Answer:

g(x) = 3f(x)

Step-by-step explanation:

We can see that for function g;

When x = 1, y = 3

When x = 2, y = 6

When x = -1, y = -3

When x = -2, y = -6

For function f;

When x = 1, y = 1

When x = 2, y = 2

When x = -1, y = -1

When x = -, y = -2

We can see that the output of g(x) is always 3 times that of f(x) for same values of x.

Thus;

g(x) = 3f(x)

(c) Charmaine compared the statistics from her team's baseball season. She determined that having fewer hits did not imply that a player
caught more or fewer balls. What should she conclude?
There is no correlation between number of hits and number of balls caught.
There is a correlation between number of hits and number of balls caught. There may or may not be causation. Further studies would have to be
done to determine this.
There is a correlation between number of hits and number of balls caught. However, there is no causation. This is because there is probably a
decrease in the number of balls caught with a decrease in the number of hits.

what equation will give the perimeter of the figure? HELP HELP HELP

Answers

Answer:

(2l + 2w) + (a + b + c)

Step-by-step explanation:

The formula for the perimeter of a rectangle is

P = 2l + 2w

so if you substitute, it becomes

P = 2(12) + 2(2)

= 24 + 4

= 28

For the perimeter of a triangle the correct formula would be

P = a + b + c

The missing side in the triangle is 3 because 15 - 12 is 3.

If you substitute, it becomes

P = 2 + 3 + 6

P = 11

If we add both perimeters together we get the full perimeter of the figure which is

28 + 11 = 39
