Answer:
b=8.5cm
Step-by-step explanation:
tanx (this represents tan theta, it's just easier to type) is equal to 0.6 and since the tanx ratio is opp/adj, we know that opp/adj = 0.6
To find what b is (adjacent as it is adjacent to the angle being used and it is not the hypotenuse), we just have to rearrange.
0.6=5.1/adj
to solve for adj, we can switch 0.6 and adj. (This works because to get adj by itself on one side you would multiply it to the other side and then divide 0.6 from both sides --> simple algebra)
so then you have
adj=5.1/0.6
adj=8.5cm
(if you want to check your solution you can use pythagoeran theorem, a^2+b^2=c^2) and sub everything in and make sure all the numbers equal the right thing!
Answer:
7mm
Step-by-step explanation:
A parallelogram has 2 sets of equal sides, so if one side is 7mm, then the opposite side is too.
Writing it in the form of a+bi we get 0+4i
Step-by-step explanation:
We need to evaluate expression -16 squared and write the result in form a+bi
The given expression is: 
We know that 
We know that 16= 4x4 = 4^2
Putting values:

So, Writing it in the form of a+bi a=0 and b=4 so, 0+4i

Answer:
0, 4, -4 and they may want you to mention formally all the kt multiples of
.
Step-by-step explanation:
Let's do the second derivative of the function: 

So now we want:

Then we have to include the zeros of the binomial (
) which as you say are +4 and -4, and also the zeros of
, which include all those values of

So an extra one that they may want you to include is k = 0
Answer:
Yes
Step-by-step explanation:
You can estimate 1/5 to 1/4 and 4/8 to 2/4 Therefore 1/4+2/4 is 3/4
