First evaluate the sq root of 45.
To do so, you have to find perfect square factors (2 x 2, 3 x 3, 4 x 4, and etc.)
The factors of 45 are 3 x 3 x 5.
Notice that there is a 3 x 3. That means you can get the 3 out of the square root and multiply with the number outside of the square root.
11(3)square root 5 - 4 square root 5
33 square root 5 - 4 square root 5
Subtracting and Adding square roots is the same thing as subtracting and Adding variables. If they have the same variable you can +/-. So if they have the same square root, then can +/-.
Answer: 29 square root 5
Hey I'm probably too late but your answer would be 26-7i
Hope this helps :)
Answer:
23
Step-by-step explanation:
According to the diagram, two sum of <1 and <2 is 180 degrees
Hence 3x+30+81 = 180
3x+111 = 180
3x =180-111
3x = 69
x = 69/3
x = 23
Answer:
B. y=2t-3
Step-by-step explanation:
First rewrite the parametric equation.
f(x)= y = at + b
Once arranged you get
2x - y =3
2x - 3 = y
f(x) = y = 2x - 3
Replace x with t, x = t
Vertically compressed means multiplying the function by a number between -1 and 1
From the given options only option C contains such an expression in which x² is multiplied with a number between -1 and 1.
Thus,
G(x) = 3/4 x²
So, the correct answer is option C
