The equation of g(x) is 
Explanation:
Given that the function f(x) is 
Also, given that the function g(x) is a vertical stretch of f(x) by a factor of 4.
We need to determine the equation of g(x)
<u>Equation of g(x):</u>
The vertical stretch of the function can be determined by multiplying the factor 4 with the function f(x).
Thus, we have,
Substituting the values,we have,
Simplifying the values, we get,
Hence, the equation of g(x) is
Answer:
oof i dont know math that well
Step-by-step explanation:
Answer:
B. 16.7
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relationship between the side adjacent to the angle and the hypotenuse involves the cosine function:
Cos = Adjacent/Hypotenuse
Filling in the numbers from your diagram gives ...
cos(50°) = x/26
Multiplying by 26 gives x.
x = 26·cos(50°)
x ≈ 16.7
Answer:
AB = 130°
Step-by-step explanation:
The inscribed angle 65° is half the measure of its intercepted arc, then
arc AB = 2 × 65° = 130°
Answer: (A) randomly selected elements within each of the strata form the sample.
Step-by-step explanation:
Stratified random sampling is a random sampling technique in statistics .
- It includes the partition of the entire population into sub-parts called strata.
- The strata are formed on the basis of the characteristics shared by members .
- After the formation of strata, researcher randomly selects participants from each strata to ensure that that the participant of every group must involve in the sample to represent each character.
Hence, the correct answer is :
(A) randomly selected elements within each of the strata form the sample.
