Answer:
x = 7 units
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
5 cm 3 cm
------------------ = ------------------------
(40 + 5) cm (3 + 2x + 10) cm
This simplifies to:
5 3
-------- = -----------
45 2x + 13
Solve for x. Cross-multiplying, we get:
10x + 65 = 135, or x = 7
So x = 7 units.
Answer:
cos(x=pi/4)=
Step-by-step explanation:
Remember that
We need to find cos(x) from the above equation.
cos(x)= 12) / 13. This solution is positive since cos(x) in the range (2pi/3, 2pi) is positive.
Now, to obtain cos(x+pi/4) lets use the relation for cos(a+b)= cos(a)*cos(b)-sin(a)*sin(b)
where a=x, b =pi/4
Hence
cos(x+pi/4) =cos(x)*cos(pi/4) - sin(x)*sin(pi/4)
cos(x+pi/4) =
cos(x=pi/4)=
Answer:
for question A the answer is 15 and for next answer is 25. question B answesr: 2nd: 3, 4,5,6,7,8. 3rd: 6,9,12,15,18 4th: 10,16,22,28,34,40..... you should get the rest by now. :)
Step-by-step explanation:
for question A you add 2 every number such as. 1 to 3 is 2. then 3 to 6 is 3 then 6 to 10 is 4 so 2, 3,4. then you figure out the same with question a part 2. for B here is an example 2nd- 3,4,5,6,7---- ypu just add one then for 3rd you add 2 then 4th you add 3... and on
Answer:
x = 6
Step-by-step explanation:
Using the balancing-equations method, you can solve this problem:
2x + 5 = 17
- 5 - 5
---- ----
2x = 12
---- ----
2 2
x = 6
