We can find the QS side that is missing by using the proportions (C) QS/SR = PO/OR.
<h3>
What do we mean by proportions?</h3>
- A proportion is an equation that equalizes two ratios.
- You could, for instance, write the ratio as follows: 1: 3 in the case of 1 boy and 3 girls (for every one boy there are 3 girls)
- The proportion formula is used to determine whether two ratios or fractions are equal.
- We can find the missing value by dividing the given values.
- The proportion formula can also be written as a: B::C:D = a/b = c/d, where a and d are the extreme terms and b and c are the mean terms.
So, a proportion that is used to determine the QS's missing side
(A) QS/OR = PO/SR
- Not possible, and the bases in the denominator have the wrong base positions.
(B) PR/PO = QS/QR
- Not possible because the order of the lines does not allow for the measurement of line length. QS/SR = PO/OR.
(C) QS/SR = PO/OR
- Given that the sides and base are both perfectly positioned within the fractions, this ratio can be used to determine the length of line QS.
Therefore, we can find the QS side that is missing by using the proportions (C) QS/SR = PO/OR.

Answer:
5.66
Step-by-step explanation:
The Square Root of 8 = 2.82842712475.
So, now we times it by two.
2 * 2.82842712475 = 5.65685424949
So, if you round it to the nearest hundredth it's 5.66.
Answer:
The curve is given by r(s)=
Step-by-step explanation:
The aec length of the curve is given by:
L=
r(t) = 3t i + (7 − 4t) j + (3 + 2t) k
r'(t)= 3 i -4 j + 2 k
|r'(t)|= 
L=
L=
s(t)=
We have to obtain t in terms of s, hence:
t=
Finally,
r(s)=
Answer:
Linked an image
Step-by-step explanation:
Okay, basically since it is y=2co3x you know that the amplitude is 2, so rather than going to +1 and -1, you now go to +2 and -2. Since it's cosine, you also know that you start at the maximum rather than the intercept, so the starting point is at (0,2).
I'm assuming that you need to graph 2 periods, and to find the periods you divide 2pi/b, so, in this case, 2pi/3
Then lastly you need to find the four points between 0 and 2pi/3, so you divide 2pi/3/4 to get 2pi/12=pi/6
If you have any other questions just comment and I'll respond when I see it.
Use Y=-2/3x + b
and then plug in (-7,-4)
-7 is x, so plug that in for x
Y=-2/3(-7) + b
and plug in y, -4
-4=-2/3(-7) +b
plug into calculator and then solve algebraically!
b doesn’t mean anything, it’s just what i used for the y axis, really you could use any letter
