The complement of an angle of 22° is an angle measuring
using the function below, calculate f(4).
Answer:
D. 8
Step-by-step explanation:
Using the graph of the function above, f(4) can be easily determined by tracing the corresponding coordinate of x = 4. When x = 4, on the x-axis, y = 8 on the y-axis.
The value of f(4), simply means, what is the value of y when x = 4.
Thus, the value of f(4) = 8.
The right answer is D. 8.

The total of your dinner bill plus tip is $16.00. You left a $3.20 tip. Write an expression to describe this situation.
Answer:
y= 16x - 3.2
Step-by-step explanation:
The expression for the given situation will be $16-$3.20 = $12.8, where $12.8 is the cost of dinner only.
What is an expression?An expression in maths is a sentence with a minimum of two numbers or variables and at least one maths operation.
Given that, The total of your dinner bill plus tip is $16.00. You left a $3.20 tip, we need to create an expression for this information,
The total cost = $16
Given for tip = $3.20
The dinner will cost = $16-$3.20 = $12.8
Therefore, the expression can be $16-$3.20 = $12.8
Hence, The expression for the given situation will be $16-$3.20 = $12.8, where $12.8 is the cost of dinner only.

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 21% of your total grade, each major test is worth 22.5%, and the final exam is worth 34%. Compute the weighted average for the following scores: 81 on the lab, 75 on the first major test, 97 on the second major test, and 84 on the final exam.
Answer:
The weighted average for the given scores is 84.27
Step-by-step explanation:
The weighted average can be calculated from the formula
Weighted average = [tex]\frac{\Sigma wx}{\Sigma w}[/tex]
Where w is the weight
and x is the score
The scores are 81, 75, 97, and 84 while their respective weights are 21% (0.21), 22.5%(0.225), 22.5%(0.225), and 34%(0.34).
From the formula
Weighted average = [tex]\frac{\Sigma wx}{\Sigma w}[/tex]
Since we have four sets of values, we can write that
Weighted average = [tex]\frac{\Sigma wx}{\Sigma w}[/tex] = [tex]\frac{w_{1}x_{1} + w_{2}x_{2} + w_{3}x_{3} + w_{4}x_{4}}{w_{1} + w_{2} + w_{3} + w_{4}}[/tex]
Let 81, 75, 97, and 84 be [tex]w_{1}, w_{2}, w_{3},[/tex] and [tex]w_{4}[/tex] respectively; then
0.21, 0.225, 0.225, and 0.34 will be [tex]x_{1}, x_{2}, x_{3},[/tex] and [tex]x_{4}[/tex] respectively.
∴ Weighted average = [tex]\frac{(81)(0.21)+(75)(0.225)+ (97)(0.225) +(84)(0.34)}{0.21+0.225+0.225+0.34}[/tex]
Weighted average = [tex]\frac{17.01+16.875+21.825+28.56}{1}[/tex]
Weighted average = 84.27
Hence, the weighted average is 84.27

Answer:
62 cm.
Step-by-step explanation:
To make a pentagon one side of the triangle must equal one side of the square.
The length of each side of the square = 48/4 = 12 cm so one side of the triangle = 12 cm.
The sum of the other 2 sides of the triangle = 38 - 12 = 26cm.
So the required perimeter = 26 + 3(12)
= 26 + 36
= 62 cm.

explain the steps to finding the vertex of g(x) = 3x2 + 12x + 15
Answer:
Vertex: (-2, 3)
Step-by-step explanation:
We first have to find the x - variable of the vertex point.
The formula to find the x - variable is x = -b/ 2a.
[tex]3x^{2} + 12x + 15[/tex]
a b c
Substitute the values into the formula.
x = - 12 / 2(3)
x = - 12 / 6
x = - 2 < - This is the x - variable
Now we have to find the y - variable of the vertex point.
To find the y - variable, we have to substitute the x value into the original equation ([tex]3x^{2} + 12x + 15[/tex]).
g(x) = y
[tex]y = 3(-2)^{2} + 12(-2) + 15\\[/tex]
[tex]y = 3(4) - 24 + 15[/tex]
[tex]y = 12 - 24 + 15[/tex]
[tex]y = - 12 + 15[/tex]
[tex]y = 3[/tex]
So, now that we have the x and y values, we can find the vertex which is (-2, 3).
