Answer:
85
Step-by-step explanation:
This is the same as asking:
What is 850 divided by 10?
When you divide it by 10 it's telling you how many times 10 can go into 850.
So, 850 / 10 = 85
Cos 45=7 under root 2 /AB
1 / Under root 2 = 7 under root 2 / AB
AB=14
Ans = 14(b)
Answer:
B. 12 + 2pi cm
Step-by-step explanation:
The shaded region is made up of 3 square sides and one half circle. The three square sides are each 4, which means that those altogether equal 12.
The circle's circumference can be found by using the equation c = (d)pi
The diameter is 4, so the whole circumference is 4pi. However, you only need half of a circle, which is represented by 2pi.
Add them all together, and you get 12 + 2pi cm.
2x^-3= 2/x^3
you can't multiple 2x to the power of -3 because is not correct. so you need to change the equation for it to give you an answer
