Answer:
Step-by-step explanation:
f(x) = 1 - x²
g(x) = [tex]\sqrt{11-4x}[/tex]
[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
[tex](\frac{f}{g})(x)=\frac{1-x^2}{\sqrt{11-4x}}[/tex]
[tex](\frac{f}{g})(-1)=\frac{1-(-1)^2}{\sqrt{11-4(-1)}}[/tex]
= [tex]\frac{1-1}{\sqrt{15}}[/tex]
= 0
(g + f)(x) = g(x) + f(x)
= [tex]\sqrt{11-4x}+1-x^2[/tex]
(g + f)(2) = [tex]\sqrt{11-4(2)}+1-(2)^2[/tex]
= [tex]\sqrt{3}-3[/tex]
(g - f)(x) = g(x) - f(x)
= [tex]\sqrt{11-4x}-(1-x^2)[/tex]
= [tex]\sqrt{11-4x}-1+x^2[/tex]
(g - f)(-1) = [tex]\sqrt{11-4(-1)}-1+(-1)^2[/tex]
= [tex]\sqrt{15}[/tex]
(g . f)(x) = g(x) × f(x)
= [tex](\sqrt{11-4x})(1-x^2)[/tex]
(g . f)(2) = [tex](\sqrt{11-4(2)})(1-(2)^2)[/tex]

On a math test, Rosie answered 36 questions correctly, which was 72%. how many questions were on the test?
Answers
Answer:
50
Step-by-step explanation:
What I did first is I converted 72% into a decimal (I work better with decimals), giving me 0.72. Then I solved the equation 36/0.72=x.
x = 50
Answer:

Let the number of questions be x.
We have:
72% of x is 36.Build an equation and solve for x:

There are 75 students in the school who can participate in the experiment. Using a table of random digits, the researchers will randomly place the students into five equally sized treatment groups suitable for comparison, four of which will receive a different teaching technique and one of which will remain a control group.
Which design is the most appropriate for this experiment?
A Randomly number each person with 1, 2, 3, 4, or 5. Assign the students to the treatment groups based on their label.
B Select a student, and identify the first digit reading from left to right on a random number table. If the first digit is 1 or 2, assign that student to the technique 1 group. Similarly, digits 3 or 4, 5 or 6, 7or 8, and 9 or 0 go with the technique 2, technique 3, technique 4, and control groups, respectively. Repeat this process for each student.
C Number each student from 1 to 75. Reading the numbers from left to right on a random number table, identify 60 unique numbers from 1 to 75. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.
D Number each student from 00 to 74. Reading the numbers from left to right on a table of random numbers and looking at two digits at a time, identify 60 unique two-digit numbers from 00 to 74. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.

Which statement about f(x) = x^2 + 16x + 3 is true
A. The function has a maximum value of 3
B. The function has a maximum value of 16
C. The function has a minimum value of -8
D. The function has a minimum value of -61
Answers
Answer:
D
Step-by-step explanation:
Given a quadratic function in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
• If a > 0 then minimum value
• If a < 0 then minimum value
For
f(x) = x² + 16x + 3
a = 1 > 0 then f(x) has a minimum value
The minimum is the value of the y- coordinate of the vertex.
The x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
Here a = 1 and b = 16 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{16}{2}[/tex] = - 8
To find the y- coordinate of the vertex, substitute x = - 8 into f(x)
f(- 8) = (- 8)² + 16(- 8) + 3 = 64 - 128 + 3 = - 61
Thus the function has a minimum value of - 61 → D

Step-by-step explanation:
Shown in the attachment are the four points graphed on a coordinate plane.
We can see that the opposite sides are parallel to each other and have the same length.
The answer cannot be B. Square because the side lengths of this quadrilateral are not all equal to each other.
The answer cannot be C. Rhombus because of the same reason as above.
The answer cannot be D. Trapezoid because the bases of the quadrilateral are not of different lengths.
Therefore, the answer must be A. Rectangle since the angles are 90° angles, and the opposite sides are parallel and equal.

Steve started with $250 and spent $20 per week. Chelsea started with nothing but saved $30 per week. Use x for time and y for savings.
Write an equation to represent Steve's situation.
Answers
Answer:
[tex]250 - 20x=y[/tex]
Step-by-step explanation:
As per the given problem, Steve starts with $250, and spent $20 a week, the problem mentions nothing about Steve's savings, therefore, one can assume that they didn't save anything. As the problem requests, parameter ([tex]x[/tex]) will be used for the time, and ([tex]y[/tex]) for the savings.
Steve's saving would be equal to his initial value, minus his expense, in essence;
[tex]250 - 20x=y[/tex]
The initial value, minus the amount spend per week multiplied by the week number will equal the savings left.
Answer:
y=250-(20x)

Step-by-step explanation:

Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)
The factors are + 3 and + 2 , since
3 × 2 = + 6 and + 3 + 2 = + 5 , then

Answer:
A) 6 square meters
Step-by-step explanation:
To find the area of a triangle you must multiple the base and the height, but in this question the base isn't given. Using the Pythagorean theorem to find the base you get 4 as the base. Now you multiply 3 and 4 to get 12 (square area), then divide it by two and get 6 (triangle area)
Steps:
b^2 = 5^2 - 3^2
b^2 = 16
[tex]\sqrt{b} = 4[/tex]
3*4 = 12
12/2 = 6 square meters
