Find the domain of f/g f(x)= sqrt 4-x^2 g(x)= sqrt 3x+4
Answers
Answer:
(-4/3, 2]
Step-by-step explanation:
f(x)= sqrt (4-x^2)
g(x) = sqrt (3x+4)
domain of f(x)/ g(x)
The domain of the numerator is
4-x^2 ≥ 0
4 ≥x^2
Taking the square root of each side
-2 ≤x≤2
The domain of the denominator
3x+4 > 0 ( the denominator cannot be zero)
3x>-4
x > -4/3
Combine the restrictions to make it most restrictive
-4/3<x≤2
In interval notation

Soln: Formula for a²+b² can be given by two types.
(i). a²+b² = (a+b)² - 2ab
= a²+2ab+b²-2ab
= a²+b²
=> LHS = RHS
Therefore, hence proved!
(ii). a²+b² = (a-b)² + 2ab
= a²-2ab+b²+2ab
=> LHS = RHS
Therefore, hence proved!
Hence, a²+b² = (a+b)² - 2ab
'OR'
a²+b² = (a-b)² + 2ab

* 4 + x -41= -15
* x -37= -15
* x= 22
• carry over -15
2 x 2 + x - 41 + 15 = 0
• solve 2 x 2
4 + x - 41 + 15 = 0
• rearrange
x + 4 - 41 + 15 = 0

Answers
Answer:
sin62 =0.883Step-by-step explanation:
0.883=1/0.836=1.133
The measure of ∠CAB is 31⁰.
Given that,
Circle O has diameter AB and chord AC.
We have to determine,
The measure of ∠CAB if BC is 62⁰.
According to the question,
The measurement of the required angle by using circle properties following all the steps given below.
The measure of the BC is 62 degrees.
If the circle has diameter AB and chord AC,
Then,
By the property of the circle,
[tex]\rm m\angle CAB = \dfrac{1}{2} \times BC \\[/tex]
Substitute the value of the BC in the equation,
[tex]m\angle CAB = \dfrac{1}{2} \times BC \\\\ m\angle CAB = \dfrac{1}{2} \times 62 \\\\ m\angle CAB = 31 \ degree \\\\[/tex]
Hence, The measure of ∠CAB is 31⁰.

find the value of x to the nearest tenth
a. -4.4
b. 7.5
c. 1.9
d. 3.5
Answers
Answer:
B
it is b because 7,5 is nearest
This is because to find x you can do the tangent of 62 and create the equation tan62=x/4
Next you need to multiply both sides by 4.
When you do this you get an answer of 7.5

The distance between the complex numbers z1 = 7 – 2i and z2 = 3 - 3i is ________
Answers
Answer:
sqrt(17)
Step-by-step explanation:
the distance is
|(7-2i) - (3-3i)| = |4 + i|
remember, the absolute value of a complex number is
|a+bi| = sqrt(a²+b²)
in our case
sqrt(4² + 1²) = sqrt(16+1) = sqrt(17)

Answer:
12 only
Step-by-step explanation:
The function is given on the graph.
What is f(0)?
This is the value of y when x = 0.
Looking at the horizontal axis, when x = 0, the vertical axis is at y = 12, and at no other point the horizontal axis is at x = 0, which means that the correct answer is given by:
