Answer:
9. a. 6
9. b. 2; 1
9. c. 3.14; 1.57
9. d. 7.57
10. 3106.86
Step-by-step explanation:
9. a. The rectangle has a length of 3 and a width of 2, so that means its area has to be 6.
9. b. The semi-circle's diameter is 2, because it is the same width as the rectangle, and finding the radius, means that you need to cut the diameter in half, so the radius of the circle is 1.
9. c. To find the full circle, we must use the formula (pi)(r)^2. So we have 3.14(1), which is just equal to pi. but since we need half the circle, we must divide the number by 2, to get the answer 1.57...
9. d. Finally we need to add up all the values together, from a. we know that the rectangle has an area of 6, and from b and c, we know the semi-circle has an area of 1.57, so we add those two numbers together we get 7.57.
10. We can do the exact same thing as number nine, which means the rectangle is 30*70=2100, The radius of the circle is 15 (30/2), the area of the circle (and since there are 2 semi circles, we don't need to divide by 2) we get 706.86, now all thats left is to add the numbers together to get the number 2806.86.

The feasible region of the result is defined by the system of inequalities.
Correct response:
The system of inequalities shown in the graph is given by the option B.
B. y ≤ x + 1
y ≤ x² - 3·x
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

The possible graph obtained from a similar question has a straight line portion and a quadratic portion.
Points on the straight line are; (0, 1), (3, 4), and (5, 6)
Therefore;
Equation of the line is; y - 1 = 1 × x
Therefore;
y = x + 1
The shaded region is below the line which gives;
y ≤ x + 1
Points on the quadratic graph are; (0, 0), (4, 4), and (2, -2).
The general form of a quadratic equation is; y = a·x² + b·x + c
Therefore, we have;
0 = a × 0 + b × 0 + c
Which gives;
c = 0
4 = a × 4² + b × 4 = 16·a + 4·b
-2 = a × 2² + b × 2 = 4·a + 2·b
4 = 16·a + 4·b...(1)
-2 = 4·a + 2·b...(2)
Multiplying equation (2) by 2 and subtracting from equation (1) gives;
2 × -2 = 2 × (4·a + 2·b) = 8·a + 4·b
-4 = 8·a + 4·b
4 - (-4) = 16·a + 4·b - (8·a + 4·b) = 8·a
8 = 8·a
a = 1
-2 = 4 × 1 + 2·b
2·b = -2 - 4 = -6
Which gives;
y = 1·x² - 3·x = x² - 3·x
The line is a solid line and shaded region is the region under the graph which gives;
y ≤ x² - 3·x
Therefore;
The inequalities in the graph are given by option B.
B. y ≤ x + 1
y ≤ x² - 3·x

The function f(x) is a quadratic function and the zeros of f(x) are -2 and 6. Assume the leading coefficient of f(x) is 1. Write the equation of the quadratic polynomial in standard form.
Answers
Step-by-step explanation:
Since the zeroes of f(x) are -2 and 6,
(x + 2) and (x - 6) are factors of f(x).
=> f(x) = (x + 2)(x - 6) = x² - 4x - 12.
Answer:
The function f(x) is a quadratic function and the zeros of f(x) are -2 and 6. Assume the leading coefficient of f(x) is 1.
(x+2) and (x-6) are the factors of f(x)
[tex]f(x) = (x + 2)(x - 6) \\ = {x}^{2} - 6x + 2x - 12 \\ = \boxed{{x}^{2} - 4x - 12}[/tex]

what is the slope and y intercept for the equation y=1/2x-5
Answers
Answer:
1/2 (slope)
-5 (y-intercept)
Step-by-step explanation:
the slope-intercept formula is y=mx+b
m is the slope and y is the y-intercept. therefore the numbers that are substituting the position of the variables are the slope and intercept
y=1/2x-5
1/2 is substituting for m which is the variable for slope
-5 is substituting for b which is the variable for the y-intercept
Write the slope-intercept form of an equation of the line that passes through the point (5, -5) and is parallel to the graph of the equation 3x + y = -2.
Answers
Answer:
[tex]y=-3x+10[/tex]
Step-by-step explanation:
Parallel equations have same slope
Therefore slope of 3x + y = -2 is same as slope of other equation.
Slope of 3x + y = -2 is
m=-3
Now we have write equation having slope -3 and passing through point (5, -5)
[tex](y+5)=-3(x-5)[/tex]
[tex]y=-3x+10[/tex]
