4 0

An equation is a relationship whose primary use is solving for a value.
An equation makes use of the equality (=) sign.
An example of an equation is x + 6 = 46.

A function is a mathematical machine whose purpose is to transform input variables into output according to the function rule.
A function can be described by an equation, a graph, a program, a table, etc.
An example of a function is y = 2x - 5.

Find the area of the composite figure in terms of the figure (use 3.14 for pi)

svp [43]

Answer:

105.12 ft²

Step-by-step explanation:

Let's first find the area of the rectangle.

$10\cdot8=80$ ft², so the rectangle has an area of 80ft².

To find the area of the semi-circle, we find the area of a whole circle and divide by two.

The formula to find the area of a circle is $\pi r^2$ . The radius is 4, as the diameter is 8.

$3.14\cdot4^2$

$3.14\cdot16$

$50.24\div2=25.12$

Add 80 and 25.12:

$80+25.12=105.12$

Hope this helped!

Ray ML and MN are perpendicular. ray MP ia an angel bisector. find the value of x .

bulgar [2K]

Answer: x = 15

Step-by-step explanation:

First, we will have to acknowledge that Angle M is a complementary angle (that means that it is 90 degrees) meaning that 2x° + 4x° will equal 90 degrees. So, let’s set up this equation.

90 = 2x + 4x

90 = 6x

$\frac{90}{6}$ = $\frac{6x}{6}$

15 = x

Therefore, the x is 15.

Find the vertex of an angle of an isosceles triangle if one base angle is 8 less than half the vertex?

skad [1K]

Vertex angle = x
1 base angle = 1/2x - 8

180-x = (1/2x-8)x2
180-x = x-16
196-x = x
196 = 2x
x=98
