Answer:
5.477
Step-by-step explanation:
Here we have to get the value √ ( x²+y² ) in this question where the values of x² and y² are given to be 20 and 10 respectively.
Let A = √ ( x²+y² ) =√(20+10) {Since the value of x² =20 and that of y² =10}
⇒ A= √30 =5.477
Therefore, the value of √ ( x²+y² ) is 5.477. (Answer)
Answer:
26
Step-by-step explanation:
(21+31+36+28+26+x)/6=28
21+31+36+28+26+x= 28×6
142+x =168
x=168-142
x=26
Answer:
14
Step-by-step explanation:
Order of operations rules require that we do any work inside parentheses first. Thus,
–(31 + 2) + 72 – (–5)^2
becomes:
-33 + 72 - 25, or
14
Important: Please use " ^ " to denote exponentiation; (-5)2 is incorrect, whereas (-5)^2 or (-5)² is correct.
Answer:
The radius of circle O is 8.5 Units
Step-by-step explanation:
Solution
The radius of a circle is refereed to as the half of the diameter.
Now,
On how to figure out the length of AB, we apply the Pythagorean's equation or formula which is given below
Thus,
a² + b² = c²
(15)² + (8)² = c²
225 + 64 = c²
√289 = √c²
Then
c = 17
What this shows is that AB is 17 units.
Since we have gotten the diameter, the next step is to divide into half the know the radius value
Therefore,
17 ÷ 2 = 8.5 Units
= 8.5 Units.
The answer is 40..........
