The domain is the set of input values for which the function is real and defined.
Find non negative values for the radicals.
For y = sqrt(3-x) if x is greater than the 3 the value under the square root would be negative which would result in a non real number.
The answer needs to be x <= 3 ( less than or equal to)
For y = sqrt(3x), if x is less than 0, the number under the sqrt root would be negative resulting in a non real number.
The answer is x >= 0 ( greater than or equal to)
Answer:
ac + 4 = b
Step-by-step explanation:
Step 1: Write equation
a = (b - 4)/c
Step 2: Multiply both sides by <em>c</em>
ac = b - 4
Step 3: Add 4 on both sides
ac + 4 = b
1) To create an equation with r isolated, you divide both sides by π and square root both (it is given that all variables are positive). The equation is √A/π = r.
2) Plugging in the numbers give us <em>√54/(22/7) = r</em>.
√54(22/7) can be rewritten as √54*7/22, which is √378/22, which can be simplified to √189/11, or about 17.18.
Answer:
15 : 175 16: 10 17: 2.5 meters
Step-by-step explanation:
15: 350 - 175 16: 25 - 15 17 since there are 100 centimeters in a meter just count and you will get the answer
122/4=30.5
30x3=91.5
Piece 1= 30.5in.
Piece 2= 91.5in
