What’s the correct answer for this?

dybincka [34]

Answer:

(A)

Step-by-step explanation:

Using the formula :

Area = 1/2 [-1(1 - 6) -7(6 - 1) -3(1 - 1)]

Area = 1/2 [5 - 35]

Area = 1/2 × -30 = |-15| = 15 units²

Which explanation can be used to derive the formula for the circumference of a circle?

Gelneren [198K]

Answer: The answer is the first explanation.

Step-by-step explanation: We are given five different options and we are to select which explanation is correct to derive the formula for a circumference of a circle.

Let 'C' be the circumference and 'd' be the diameter of a circle. Now, we will write the ratio of the circumference to the diameter as

$\dfrac{\textup{C}}{\textup{d}}.$

Also, we know that

$\dfrac{\textup{C}}{\textup{d}}=\pi.$

And diameter of a circle is twice the radius, so

$d=2r.$

Therefore,

$\dfrac{\textup{C}}{2\textup{r}}=\pi\\\\\Rightarrow \textup{C}=2\pi \textup{r}.$

This is the formula for the circumference of a circle. Since this explanation matches exactly with the first option, so the correct option is

(a). Find the relationship between the circumference and the diameter by dividing the length of the circumference and length of the diameter. Use this quotient to set up an equation to showing the ratio of the circumference over the diameter equals to π . Then rearrange the equation to solve for the circumference. Substitute 2 times the radius for the diameter.

LCM for 2 and 13 plz help me out

Andrei [34K]

[ Answer ]

$\boxed{\bold{LCM \ = \ 26}}$

[ Explanation ]

Find LCM For 2 & 13

-------------------------------------

LCM - The smallest number that two or more numbers can evenly fit into

LCM - What We Know
2 & 13 Must Evenly Fit
Must Be Smallest Number They Both Fit Into
Multiple Of Two Or More Numbers

The Smallest Number That Both 2 & 13 Evenly Fit Into Is 26

26 ÷ 2 = 13

26 ÷ 13 = 2

$\boxed{\bold{[] \ Eclipsed \ []}}$

Determine which function has a greater initial value and explain how you know.

murzikaleks [220]

Answer:

Function 2 has a greater initial valueStep-by-step explanation:An initial value of a function, aka y-intercept, is obtained by using x=0 and evaluating the function at that point. Evaluating the two functions given:Function1: Function2 has value 3 for x=0So, Function 2 has a greater initial valueFunction 2 has a greater initial valueStep-by-step explanation:An initial value of a function, aka y-intercept, is obtained by using x=0 and evaluating the function at that point.
