How do functions work? Could someone explain how to know which questions are functions or not

belka [17]

Answer:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a speceified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

Step-by-step explanation:

here is a step by step equation:

f(x) = x + 7

if:

x=2

then:

f(2) = 2 + 7 = 9

A function is linear if it can be defined by

f(x) = mx + b

Makes sense? Hope I helped

plus I'm in middle school learning this also.

Find the circumference of a circle that has a diameter of 4 m. Use 3.14 for pi. m

Arturiano [62]

Answer:

<h2>12.56 m</h2>

Step-by-step explanation:

The formula of a circumference of a circle:

$C=d\pi$

<em>d</em> - <em>diameter</em>

<em />

We have <em>d = 4m</em>.

Substitute:

$C=4\pi\ m$

Use 3.14 for π:

$C\approx4(3.14)=12.56\ m$

Hi there. I am having an issue figuring out which is the base and which is the length.

Paha777 [63]

We can split the given figure in 2 right triangles:

So, in order to get the area of each triangle, we need to find the base, denoted by x in both of them. Since both are right triangles, we can to apply Pythagoresn theorem. By applying this theorem to right hand side triangle, we have

$x^2+8^2=17^2$

so we have

$\begin{gathered} x^2+64=289 \\ then \\ x^2=289-64 \\ x^2=225 \end{gathered}$

Then, x is given by

$x=\sqrt{225}=15$

Then, the area of the left triangle is given by

$A_1=\frac{base\times height}{2}=\frac{15\times36}{2}=270in^2$

Similarly, the area of the second triangle is given by

$A_2=\frac{base\times height}{2}=\frac{15\times8}{2}=60in^2$

Then, the area of the entire figure is the sum of the area of the 2 triangles, that is,

$A=A_1+A_2=270+60=330in^2$

Therefore, the answer is: 330 square inches
