Answer:
f(x) = x² - 4x - 5
Step-by-step explanation:
given the roots of a parabola x = a and x = b , then the factors are
(x - a) and (x - b)
the function is then the product of the roots , that is
f(x) = (x - a)(x - b)
from the graph the roots ( where graph crosses the x- axis ) are
x = - 1 and x = 5 , then corresponding factors are
(x - (- 1) ) and (x - 5) , that is (x + 1) and (x - 5) , then
f(x) = (x + 1)(x - 5) ← expand using FOIL
= x² - 5x + x - 5
f(x) = x² - 4x - 5

every 10 years, the u.s. census bureau attempts to count every person living in the united states. to check the accuracy of their count in a certain city, they draw a sample of census districts (roughly equivalent to a city block) and recount everyone in the sampled districts. what kind of sample is formed by the people who are recounted?
Answer: The sample formed by the people who are recounted in the U.S. Census Bureau's accuracy check is a random sample. This is because the census districts are selected in a random manner, with each district having an equal chance of being selected. Random sampling is a method of selecting a sample from a larger population in which each member of the population has an equal chance of being selected. This ensures that the sample is representative of the population as a whole and allows for the estimation of population characteristics with a known degree of precision.

After using proportion the enlarged photo length is C)15 inches.
What is proportion?
A percentage is created when two ratios are equal to one another. We write proportions to construct equivalent ratios and to resolve unclear values. a comparison of two integers and their proportions. According to the law of proportion, two sets of given numbers are said to be directly proportional to one another if they grow or shrink in the same ratio.
Here According to the question before enlargement the width is 4 inches and length is 6 inches. Taking proportion between before and after enlargement of the measurements then,
=> [tex]\frac{ width}{length}[/tex]
=> [tex]\frac{4}{6}=\frac{10}{x}[/tex]
=> x = [tex]\frac{10\times 6}{4}[/tex]

Arnold is testing a new train locomotive on circular rail track with a radius of 0. 9 kilometers. How many times around the track does Arnold need to run the train to cover a distance of at least 50 kilometers?
So, Arnold needs to run the train 9 times around the track to cover a distance of at least 50 kilometers.
We know that the radius of the circular rail track is 0.9 kilometers, so the circumference of the track can be found using the formula C = 2πr, where C is the circumference and r is the radius of the circle.
C = 2 * 3.14 * 0.9 = 5.652 km
To find out how many times Arnold needs to run the train around the track to cover a distance of at least 50 kilometers, we need to divide 50 by the circumference of the track.
50 km / 5.652 km = 8.9
Arnold needs to run the train around the track approximately 8.9 times to cover a distance of at least 50 kilometers.
To be more precise, we can round up the result, so Arnold needs to run the train 9 times around the track to cover a distance of at least 50 kilometers.

Point D is located at (-6,-5) on the coordinate plane. Point D is reflected over the x-axis to create point D' . What ordered pair describes the location of D'
The ordered pair which describes the location of D' include the following: (-6, 5).
What is a reflection?In Geometry, a reflection over the x-axis is given by this transformation rule (x, y) → (x, -y). This ultimately implies that, a reflection over the x-axis would maintain the same x-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.
By applying a reflection over the x-axis to the coordinates of this triangle the image coordinates include the following:
(x, y) → (x, -y)
Ordered pair D = (-6, -5) → Ordered pair D' = (-6, -(-5)) = (-6, 5).
In conclusion, we can logically deduce that the location of D' after a reflection over the x-axis is (-6, 5).

a fair die is cast until a 6 appears what is the probability that it must be cast more than 5 times times
The probability that the fair die must be cast more than 5 times is 0.4315 or 43.15%.
The probability that it must be cast more than five times is the complement of the probability that it will be cast five or less times.
The probability of getting a 6 on the first roll is 1/6, the probability of not getting a 6 on the first roll is 5/6. The probability of getting a 6 on the second roll, given that it was not obtained on the first roll, is 1/6. The probability of getting a 6 on the third roll, given that it was not obtained on the first and second rolls is 1/6 and so on.
The probability of not getting a 6 in five rolls is (5/6)⁵. The probability of getting a 6 on the fifth roll is 1/6. The probability of getting a 6 on the fifth roll or not getting it on the first five rolls is (5/6)⁵ + 1/6.
So the probability of getting a 6 in five rolls or less is (5/6)⁵ + 1/6.
Therefore, the probability of getting a 6 in more than five rolls is 1 - ((5/6)⁵ + 1/6) = 0.4315

A function is a mathematical relation between two sets of values that assigns a unique output to each given input.
What is a function?
A function in mathematics from a set X to a set Y allocates precisely one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.
I) f(x)- 2G(x) = 5x³-8x²+18x-13
II) 2f(x)+3G(x) = 31x³+26x²-34x+30
III) 1/2f(x)+ G(x) = 17/2x³+8x²-12x19/2
Here, we have
f(x)= 11x³+4x²-2x+3, G(x)= 3x³+6x²-10x+8
We have to find I) f(x)- 2G(x), ii) 2f(x)+3G(x), iii) 1/2f(x)+ G(x)
I) f(x)- 2G(x) = 11x³+4x²-2x+3 -2(3x³+6x²-10x+8 )
= 11x³+4x²-2x+3 - 6x³-12x²+20x-16
= 5x³-8x²+18x-13
Hence, the value of f(x)- 2G(x) is 5x³-8x²+18x-13.
II) 2f(x)+3G(x) = 2(11x³+4x²-2x+3)+3(3x³+6x²-10x+8 )
= 22x³+8x²-4x+6+9x³+18x²-30x+24
= 31x³+26x²-34x+30
Hence, the value of 2f(x)+3G(x) is 31x³+26x²-34x+30.
III) 1/2f(x)+ G(x) = 1/2(11x³+4x²-2x+3) + (3x³+6x²-10x+8)
= 11/2x³+2x²-2x+3/2+3x³+6x²-10x+8
= 17/2x³+8x²-12x19/2
Hence, the value of 1/2f(x)+ G(x) is 17/2x³+8x²-12x19/2.

Answer: 3
Step-by-step explanation:
Answer:
No. Divide the group of 12 small blue squares by small groups of 4 small blue squares, and you get 3, not 0.03.
Step-by-step explanation:
6.
The large square is divided into small squares. There are 10 small squares on each side of the large square. Since 10 × 10 = 100, the large square is divided into 100 small squares.
The large square is 1 unit.
Since the large square, 1 unit, is divided into 100 small squares, then each small square represents 1/100 of a unit, or 0.01 unit as a decimal.
There are 12 small squares shaded blued.
Each small square is 0.01 unit, so 12 squares represent 12 × 0.01 = 0.12.
The group of 12 small squares is divided into 3 smaller groups of 4 small squares each. Each group of 4 small squares represents 4 × 0.01, or 0.04.
Now we are asked what 0.12 ÷ 0.04 equals.
Look at the figure. The 0.12 of the entire blue shading makes up 3 groups of 0.04 size, so 0.12 ÷ 0.04 = 3.
The division 0.12 ÷ 0.04 is the same as asking how many groups of 4 small squares can you fit in the group of 12 small squares? The answer is 3.
0.12 ÷ 0.04 = 3
The answer 0.12 ÷ 0.04 = 0.03 is incorrect.
Answer: No. Divide the group of 12 small blue squares by small groups of 4 small blue squares, and you get 3, not 0.03.

Milos is an avid maker of tinctures, which are concentrated liquid forms of natural herbs. One common herb that is formed into a tincture is the vanilla bean, which is sold in stores under the moniker Vanilla Extract. One means by which to create a tincture is by soaking the herb in grain alcohol for several weeks. It is possible to purchase grain alcohol called Everclear, which is 97% alcohol; However, vanilla requires a 60% alcohol solution (97% is too strong). To adjust for alcohol that is too strong, the solution can be diluted with water (0% alcohol) to achieve the desired concentration. Suppose Milos is planning on making a 12-ounce vanilla extract. How much water and alcohol should he use?
The alcohol required to make 12 ounce vanilla extract is 7.42 ounces.
In the given question, we have to find how much water and alcohol he should use.
Given that vanilla extract requires a 60% alcohol solution and that Given that the pure alcohol content in 12 ounces of vanilla extract is 97%.
Let x denote the alcohol required in ounces.
Let y represent the needed water in ounces.
Then, we must find x and y such that
x + y = 12
Given the desired strength, the volume needed, and the pure alcohol percentage, the following formula can be used to determine the pure alcohol:
Required Pure Alcohol = Desired strength × Volume required Pure alcohol content
x = 60 × 12
97x = 7.42
Therefore the alcohol required to make 12 ounce vanilla extract is 7.42 ounces.
