Answer:

Step-by-step explanation:
we have

Find out the domain
we know that
The radicand must be greater than or equal to zero
so

The domain is the interval -----> [0,∞)
All real numbers greater than or equal to zero

Answer:
Yes, No, No, No
Step-by-step explanation:
To decide whether the point lies on the circle, what you need to do it simply substituting the x and y values into the equation and check if it add up to be 25
(-5)² + 0² = 25, = RHS [Yes]
1² + (√7)² = 8, ≠ RHS [No]
(√21)² + (-3)² = 30, ≠RHS [No]
0² + 7² = 49, ≠RHS [No]
<h2><u>ANSWER</u></h2>
y = 8
x= -1
Step-by-step explanation:
hope it helps ✌️✌️
If the sum of two numbers is x
Then the equation is like this:
a+b = x
Then it says one of the number is 12. Change either a or b into 12
12 + b =x
If we want to find the other number, we need the make it into the subject
b = x - 12
Hope that help.
Answer:
v= s/t = sqrt(360^2+480^2) x 0.3048/0.5 = 365.76(m/s)
Step-by-step explanation:
s =sqrt(360^2+480^2)
s-ft-to-m = s*0.3048
t = 0.5
