Answer:

C

Step-by-step explanation:

A piece wise function involves two or more functions over specific intervals. The equations of the two lines are the following y=x+1 and y=-x+2. The line y=-x+2 continues to the right and has an open circle at the end. So this point is not included. This means the interval is a greater than sign but not equal to.  This means C is the answer.

The area of the square adjacent to two sides of a right triangle are 29.25 square units and 13 units 30 POINTS
Otrada [13]

Answer:

x=6.5\ units

Step-by-step explanation:

step 1

Find the length side of the smaller square

The area of the square is equal to

A=a^{2}

so

a^{2}=13

a=\sqrt{13}\ units

step 2

Find the length side of the larger square

The area of the square is equal to

A=b^{2}

so

b^{2}=29.25

b=\sqrt{29.25}\ units

step 3

Find the value of x

Applying the Pythagoras Theorem

x^{2} =a^{2}+b^{2}

substitute the values

x^{2} =13+29.25

x^{2} =42.25

x=6.5\ units

Write the following polar equation in Cartesian coordinates:
maks197457 [2]
Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)

Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))

Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y

Help plz its math and i will give brainlest if u answer
lesantik [10]

Answer:

not a right triangle

Step-by-step explanation:

We can use the Pythagorean theorem to see if it is a right triangle

a^2 + b^2 = c^2

15^2 + 12^2 = 21^2

225 + 144 = 441

369 = 441

This is not true so it is not a right triangle

What are the coordinates of the midpoint of CD¯¯¯¯¯ where C(2, −6) and D(4, 10)?
qaws [65]
The answer is (3,2). I did this by drawing a graph, inserting the two midpoints you provided, and put in each potential midpoint, finding (3,2) is the only midpoint that connects to the line.
