The degree of the polynomial function f(x) is 4.
The roots of the equation f(x)=0 are −6 , −2 , 1, and 3.
Which graph could be the graph of f(x) ?
Answers
Answer:
option B
Step-by-step explanation:
The degree of the polynomial function f(x) is 4.
The roots of the equation f(x)=0 are [tex]−6 , −2 , 1,[/tex] and 3.
We are given with four roots. they are the x intercepts
x intercepts are [tex]−6 , −2 , 1,[/tex] and 3
The polynomial has degree 4, the polynomial goes up on both sides
We look at the graph that has x intercepts [tex]−6 , −2 , 1,[/tex] and 3 and both ends of the graph goes up
option B is correct
The graph that could be the graph of f(x) is;
The second graph which is the one at the top right
We are told that;
Degree of polynomial f(x) = 4; This means it has 4 roots
Roots of polynomial = -6, -2, -1 and 3
The roots of a polynomial simply means the values of x at which the function f(x) is equal to zero. This simply means the x- intercept is the root.
Thus, the x-intercept of the correct graph should be at;
x = -6; x = -2 ; x = -1 and x = 3
Looking at the given graphs, the only one that has its' x-intercepts at x = -6; x = -2 ; x = -1 and x = 3 is the second graph at the top right.

Answers
Answer:
Option B. 14.8 units³ is the answer.
Step-by-step explanation:
It is given in the question A solid right pyramid which has a regular hexagonal base with area = 7.4 unit²
Height of the pyramid = 6 units.
We have to calculate the volume of the pyramid.
Since volume of the pyramid = (1/3)×Area of the base × height
Volume = (1/3)×7.4×6 = 7.4 × 2 = 14.8 units³
Therefore option B. 14.8 units³ is the answer.
It should be noted that the volume of the pyramid will be 14.8 unit³.
How to calculate the volume of the pyramidFrom the information given, the solid right pyramid has a regular hexagonal base with an area of 7.4 units².
The height of the pyramid is also 6 units. Therefore, the volume of the pyramid will be:
= 1/3 × Area of the base × height

How many length 6 passwords with 1 number 1 upper and 1 lower?
Answers
- No passwords without numbers allowed, so we subtract 52⁶
- No passwords without uppercase allowed, so we subtract 36⁶
- No passwords without lowercase allowed, so we subtract 36⁶
Now we have subtracted the passwords of all capitals twice, so we have to add those back in: add 26⁶
Same for all lowercase and all numbers: add 26⁶ and 10⁶
end result: 62⁶ -52⁶-36⁶-36⁶ + 26⁶+26⁶+10⁶ = 33294892800

On a isosceles triangle, the base angles are the same.

To know X, we subtract 112° from the total

The cosine function is used to find the length of the hypotenuse of a triangle by utilizing the Pythagorean theorem.
The trigonometric function used to find the length of the hypotenuse of a triangle is the cosine function. In a right triangle, the cosine function is defined as the ratio between the length of the adjacent side to the length of the hypotenuse.
To find the length of the hypotenuse, you can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the hypotenuse.
For example, if the lengths of the shorter sides are 9 blocks and 5 blocks, then the length of the hypotenuse would be √(9² + 5²) = √(81 + 25) = √106 = 10.3 blocks.

an artist is cutting pieces of ribbon to use in a project. Each piece he cuts measures 7/8 inch. The aritst cuts off 5 pieces. How many total inches of ribbon has he cut off?
Answers
The artist has cut off a total of 4 and 3/8 inches of ribbon for his project by multiplying the length of one piece (7/8 inch) by the total number of pieces cut (5).
Explanation:The question involves a straightforward arithmetic operation of multiplication. Each piece of ribbon the artist cuts measures 7/8 inch, and he cuts off 5 pieces in total. To find the total length of ribbon cut off, we multiply the length of one piece (7/8 inch) by the number of pieces cut (5).
Calculation: \(\frac{7}{8} \text{ inch} \times 5 = \frac{35}{8} \text{ inches} = 4 \frac{3}{8} \text{ inches}\)
Therefore, the artist has cut off a total of 4 and 3/8 inches of ribbon for his project. This example demonstrates a practical application of multiplication in a real-world context, specifically within arts and crafts projects.

Answers
For your particular problem, I’ve included a picture showing how that specific calculation is done. :)

It is given that,
The x component of the vector is, [tex]v_x=7.6\ units[/tex]
The y component of the vector is, [tex]v_y=-6.6\ units[/tex]
We need to find the magnitude of vector v. The magnitude of any vector is calculated as :
[tex]|v|=\sqrt{v_x^2+v_y^2}[/tex]
[tex]|v|=\sqrt{(7.6)^2+(-6.6)^2}[/tex]

Question 5.

4a
area is 4ab
2a
Answer:
#4) 1/2(ab); #5) 3a, 4a, 4ab, 2a
Step-by-step explanation:
#4) Take the top triangle. The height will be the difference in the y-coordinates of J and M:
b-0 = b
The base of the triangle would be the difference in the x-coordinates of J and K:
a-0 = a
The area is given by the formula A=1/2bh, where b is the base and h is the height; substituting our height and base, we have
A=1/2(b)(a) = 1/2(ab)
#5) To find the midpoint of a section, we add together the x-coordinates and divide by to, and add together the y-coordinates and divide by 2.
The endpoints of FE are (4a, 0) and (2a, 2b). This makes R:
[tex](\frac{2a+4a}{2},\frac{2b+0}{2})\\\\=(\frac{6a}{2},\frac{2b}{2})\\\\=(3a, b)[/tex]
The length of DF can be found by subtracting the x-coordinates:
4a-0 = 4a
The area is then found by multiplying 1/2 by the base and the height:
A=1/2(4a)(2b) = 1/2(8ab) = 4ab
The length of QR can be found by subtracting the x-coordinates:
3a-a = 2a

Option B: Increase the amount of money they save each month by $80 from what they've been saving. Which of the following is a true statement? a. Only option A will allow them to meet their goal. b.

Answers
To meet their goal of saving $8,000 for their wedding, Mike and Kate need to adjust their plan. Increasing the amount they save each month by $80 (Option B) will allow them to reach their goal.
Explanation:To determine which option will allow Mike and Kate to meet their goal of saving $8,000 for their wedding, we need to analyze the information given. They saved $4,000 in the first year, which means they saved $4,000 in 12 months. To reach their goal, they need to save an additional $4,000 in 8 months.
Option A: If they stay with saving the same amount they've been saving each month, they will save the same amount each month for the remaining 8 months. Therefore, they will not reach their goal of $8,000.
Option B: If they increase the amount they save each month by $80, they will be saving $80 more each month for the remaining 8 months. This will result in them saving an additional $640 ($80 x 8 months) and reaching their goal of $8,000.
Therefore, the correct answer is Option B - Only option B will allow them to meet their goal.

All trapezoids are parallelograms.
All parallelograms are trapezoids.
All rectangles are squares.
All rhombuses are rectangles.
Answers
Answer:
The answer is B. All parallelograms are trapezoids.
Step-by-step explanation:
The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. That makes the opposite of facing sides are parallel to each other. The the definition of trapezoid is a convex quadrilateral with at least one pair of parallel sides. Therefore, all parallelograms are trapezoids.
The true statement among the given options is, B. All parallelograms are trapezoids.
A trapezoid is a quadrilateral with at least one pair of parallel sides, but it doesn't require all sides to be parallel. Therefore, not all trapezoids are parallelograms. (Statement A is false)
A parallelogram is a quadrilateral with both pairs of opposite sides parallel. Every trapezoid has at least one pair of parallel sides, so it can be considered a special case of a parallelogram. Therefore, all trapezoids are parallelograms. (Statement B is true)
A rectangle is a quadrilateral with all four angles equal to 90 degrees. It has opposite sides that are parallel and equal in length. A square is a special type of rectangle with all sides of equal length. However, not all rectangles have all sides of equal length, so statement C is false.
A rhombus is a quadrilateral with all four sides of equal length. It has opposite sides that are parallel, making it a parallelogram. Since a rectangle is a parallelogram with right angles, and a rhombus is a parallelogram with equal sides. Therefore, statement D is also false.

To solve the equation 7(2 + 5v) = 3v + 14, we can simplify and isolate the variable v.
Expanding the left side of the equation:
7(2 + 5v) = 14 + 35v
Now we have:
14 + 35v = 3v + 14
Next, we can combine like terms:
35v - 3v = 14 - 14
