Answer:
Descriptive research design
Step-by-step explanation:
Descriptive research design is a type of quantitative research design that tends to describe/depict the current status (condition) of a particular variable or phenomenon. In the case above, the research is quantitative because it deals with quantifiable data, which is the preference(quantity) of cosmetics. Savannah wanted to describe the preference of cosmetic use among adolescents, young adult, middle adult and the late adult women, which makes it a descriptive research design. It does not involve conducting experiment, or generating correlations etc.
Therefore, it is a Descriptive research design
Answer:
m ∠ W is 58.2°
Step-by-step explanation:
Given:
XY = 15
WZ = 22
∠ XZY =25°
To Find:
m ∠ W = ?
Solution:
In right angle triangle Δ XZY, by Sine identity we have

∴ XZ = 35.49
Now in right angle triangle Δ WZX, by tangent identity we have

∴m ∠W =58.2°
If f(x) = 5x - 16, then value of f(9) is 29
<em><u>Solution:</u></em>
Given function is f(x) = 5x - 16
We are asked to find the value of f(9)
To find the value of f(9), we have to substitute x = 9 in given function and solve the function
Therefore, substitute x = 9
f(x) = 5x - 16
f(9) = 5(9) - 16
Multiply 5 with 9 which gives 45
f(9) = 45 - 16
Subtract 16 from 45
f(9) = 29
Thus value of f(9) is 29
