8
Answer:
The value of f(5) is:
-8
Step-by-step explanation:
Lets make table which represents the function.
Th table has 2 columns, first column contains values for x, second column contains values of y
The table has 4 rows, which means that there are 4 values of x, which corresponds to 4 values of y.
The table is given as:
x f(x)
-4 -2
-1 5
3 4
5 -8
We need to find the value of f(5).
We can get the value of f(5) if we substitute x = 5 into f(x)
We can see in the table, that if we substitute x=5 in f(x), we get the value of f(5) = -8
Which is the answer
Answer:
F(5)=8

WHAT IS THE PYTHOGERON TRIPLETS IF ONE NUMBER IS 36
Answer:
Step-by-step
Let the given number be n>2.
For n even, n2+((n/2)2–1)2=((n/2)2+1)2.
For n odd, n2+((n2–1)/2)2=((n2+1)/2)2
use the forumla to find u r answer
standard form of a pythagorean triplet is 2m, m²+1, m²-1
let us take 2m as 36. so
2m=36, m=36/2
therefore m=18
m²+1 =18²+1 = 324+1 =325
m²-1 =18²-1 = 324-1 =323
therefore 36,325,323 form a pythagorean triplet.
For checking, 36²+323² should be equal to 325²

A.-2
B.-
[tex] \frac{9}{2} [/tex]
c. -
[tex] \frac{2}{9} [/tex]
D.2
E.9
Answer:
slope = - [tex]\frac{2}{9}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 9y = - 18 ( subtract 2x from both sides )
9y = - 2x - 18 ( divide all terms by 9 )
y = - [tex]\frac{2}{9}[/tex] x - 2 ← in slope- intercept form
with slope m = - [tex]\frac{2}{9}[/tex]

Which of the following discrete random variables could be represented by a
probability histogram whose bars are all the same height?
O A. The number of goals scored per game by a soccer team in one
season
B. The ages of students in a high school
O C. The outcomes of spinning a spinner with five equal sections
O D. The outcomes of rolling a weighted die
Answer: The outcome of spinning a spinner with five equal outcomes
Step-by-step explanation:
The discrete random variable that could be represented by a probability histogram whose bars are all the same height is;
Option C; The outcomes of spinning a spinner with five equal sections
The probability histogram is a type of histogram whereby the height of each bar shows the true probability of each outcome of a specific number of trials.
Now, let us look at the options;
Option A; This cannot be represented by a probability histogram because it doesn't show probability.
Option B; This cannot be represented by a probability histogram because it shows just ages and doesn't show probability.
Option C; This can be be represented by a probability histogram because it shows the probability of each outcome of spinning five equal sections.
Option D; This cannot be represented by a probability histogram because it should show the probability of each outcome and not just that of one weighted die.

Samantha and Luis are attempting to determine the average number of library books that seventh-grade students check out at one time. Samantha surveys every other seventh grade student leaving the library. She samples a total of 40 of the 200 seventh graders. Luis samples 30 of the 200 seventh grade students at random in the school cafeteria. Whose sample is the most random? Luis because his sample is taken from the population of all seventh graders Luis because he samples fewer students Samantha because she samples more students Samantha because her sample is taken from the population of students who use the library
Answer:
Luis, because his sample is taken from the population of all seventh graders. However, Samanthan has the advantage of having a bigger sample, and that makes it more representative.
Taking the sample of the library as Samantha did, is biased, because most of the students there is checking a book, and the aim of the study is not only the ones that use the library, but in general the seventh grade students.

Dominic buys a 64-ounce container of salad mix. About how many ounces of romaine lettuce does the container have? 6 ounces 12 ounces 18 ounces 27 ounces
Hi! here's your answer!ヾ(￣▽￣)
Step-by-step explanation:
Your answer is 18 ounces of romaine lettuce!
Have a nice day/night~ (｡･∀･)ﾉﾞ
The correct option is 18 ounces. The weight of romaine lettuce in salad mix container is 17.28 ounces.
Given to us:
iceberg = 40%
romaine = 27%
spinach = 15%
arugula = 12%
carrots = 6%
The total weight of salad mix container = 64 ounces
Romaine lettuce the container have is 27% of the total weight of salad mix container Dominic buys. Therefore,
weight of romaine lettuce in salad mix container,
= 27% of the total weight of salad mix container
= 27% of 64 ounces
= [tex]\dfrac{27\times 64}{100}[/tex]
=17.28 ounces
Hence, the weight of romaine lettuce in salad mix container is 17.28 ounces.

5. A silo was constructed at a farm in the shape of a right circular cylinder. It was built with an
approximate volume of 842,411 cubic meters and a height of 85 meters. What was the length of the diameter
of the base, to the nearest meter?
Answer: 112 meters
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder (V) : π x radius ² x heightReplacing with the values given :
842,411 = π x r ² x 85
Solving for r:
842,411 / (π x 85) = r²
3,154.67 = r²
√3,154.67 = r
56.16 m = r
Finally, we have to multiply the radius by 2 to obtain the diameter:
56.16 x 2 = 112 meters

the angle with the horizontal at
which the balloon rises.
a.
b.
find (to the nearest 10 feet) its
distance from the starting point
after one minute.
Answer:
a) 63°
b) 600ft
Step-by-step explanation:
To solve the above question, we would be using Trigonometric function
a) Find (to the nearest whole degree)
the angle with the horizontal at
which the balloon rises.
This above question a is a right angled triangle that is solved for using Trigonometric function of tan
From the question, we told that,
Vertical distance ( opposite side) = 10 feet
Horizontal distance ( adjacent side) = 5 feet.
Tan θ = opposite side/ adjacent side
Tan θ = 10/5
Tan θ = 2
θ = arc tan (2) or tan -¹(2)
θ = 63.434948823°
θ = 63°
The angle with the horizontal at
which the balloon rises to the nearest whole degree is 63°
b) find (to the nearest 10 feet) its
distance from the starting point
after one minute.
Distance = Speed × time
Time is given in the question as 1 minute
We would convert it to seconds = 60 seconds
We are told in the question that the balloon rises vertically at the speed of 10ft/s
Distance = 10ft/s × 60seconds
Distance from the starting point per minute = 600ft
