When dealing with roots, we want to factor to see if it's possible
now since we're dealing with square roots, we circle every pair of numbers we see in the final factoring
so..
now for every circled pair, we take only 1 of the 2 circled and bring it outside
anything left uncircled stays inside the root
so..
now simply multiply
You are absolutely right.
Answer:
0; 2; 6; 0 or -1
Step-by-step explanation:
If the question says "f(a)=" they are asking for the y value with the given x such as the two first ones.
If it's "f(x)=a than x=" they are asking you what x is when the (bolded) x is a given value.
<h3>
Answer: 9 meters</h3>
===========================================
Work Shown:
- side a = 8
- side b = 5
- angle C = 88 degrees
Applying the law of cosines
c^2 = a^2 + b^2 - 2*a*b*cos(C)
c^2 = 8^2 + 5^2 - 2*8*5*cos(88)
c^2 = 64 + 25 - 80*cos(88)
c^2 = 86.2080403
c = sqrt(86.2080403)
c = 9.2848285
c = 9
Technically he needs 10 meters of rope because of the extra 0.28 portion, but I'll stick with 9 meters since your teacher said to round to the nearest whole number.
The percentage change in volume from cylinder A to cylinder B; D: 100%
<h3>How to find the percentage change in Volume?</h3>
Formula for Volume of a Cylinder is;
V = πr²h
Thus, volume of Cylinder A is;
V_a = π * 7² * 5
V_a = 245π
Thus, percentage change in volume is;
[245π/(490π - 490π)] * 100%
Percentage change in volume = 100%
