How to find arc length

1 answer:

3 0

A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.

The answer is 1/4.

The genes when combined must be Heterozygous, meaning they have one dominant and one recessive, Celia must have gotten the 1/4 recessive, and it won't change the way genetics are just because you've already had offspring, the percentage stays the same.

Answer:

3n+4 or n3+4

Step-by-step explanation:

7,10,13,16

they all have a difference of 3

so that's 3n

start with the first one: 3(1)+?=7

7-3=4

3n+4

use this for the other ones to double check

Use the information given to enter an equation in standard form. (−1, 1) and (0, 6) are on the line.

liubo4ka [24]

Answer: -5x+y=6

Step-by-step explanation:

Given

Points on line $(-1,1)\ \text{and}\ (0,6)$

The standard form of an equation is $ax+by=c$

Using the two-point form of a line

$\Rightarrow \dfrac{y-1}{x+1}=\dfrac{6-1}{0+1}\\\Rightarrow \dfrac{y-1}{x+1}=\dfrac{5}{1}\\\Rightarrow y-1=5x+5\\\Rightarrow y-5x=6\\\Rightarrow -5x+y=6$
