f(x)=4x+1 and g(x)=x^2-5 find f+g (x)
Answer & Step-by-step explanation:
When we see (f + g)(x), it means that we are adding together f(x) and g(x).
f(x) = 4x + 1
g(x) = x² - 5
(f + g)(x) = (4x + 1) + (x² - 5)
Combine like terms and make sure x² is in the front of the expression so you are following the rules of exponents when in standard form.
(f + g)(x) = x² + 4x - 4
So, (f + g)(x) equals x² + 4x - 4
Which survey is biased?
A) going to a grocery store and asking people what their favorite grocery store is.
B) going to the grocery store and asking people what type of food is their favorite
C) going to a grocery store and asking people what clothing store is their favorite
D) Going to grocery store and asking people what radio station do you listen to most often
Answer:
A
Step-by-step explanation:
A is biased because those people at the grocery store will most likely like that grocery store, since they went there to shop in the first place.
B, C, and D are not biased because there is no correlation between the grocery store and the survey questions.
Option b) going to grocery store and asking people what type of food is their favourite
Find the volume of a pyramid with a square base, where the perimeter of the base is
15.8 ft and the height of the pyramid is 20.4 ft. Round your answer to the nearest
tenth of a cubic foot.
(It’s on deltamath)
The volume of the given pyramid is 106.1 cubic foot.
To Find the Volume of a pyramid with a square base
Given:
The perimeter of the base is 15.8 feet
The base of the pyramid is square given of side say L .
Thus, from the formula of perimeter of square,
⇒ 4*L = 15.8 feet
∴ L = 3.95 feet
Now the base area of the pyramid is [tex]L^{2}[/tex] as it is a square .
∴ Base area = 3.95*3.95 square feet
= 15.6025 square foot
Now, formula for volume of the pyramid
= 1/3 * base area * height
⇒ Volume = 1/3 * 15.6025 * 20.4 cubic foot
∴ Volume = 106.097 cubic foot
Thus volume of the given pyramid is 106.1 cubic foot rounded off to nearest tenth.

Answer: m√M = 98°
Step-by-step explanation:
x + x + 6 + 3x - 16 = 180
5x - 10 = 180
5x = 180 + 10
x = 190 / 5 = 38
m√M = 3x - 16
= 3(38) - 16
= 98°
Answer:
m<M = 98 deg
Step-by-step explanation:
Theorem
The sum of the measures of the angles of a triangle is 180 degrees.
Now we set the sum of the measures of the angles equal to 180 and solve for x.
3x - 16 + x + 6 + x = 180
5x - 10 = 180
5x = 190
x = 38
Now that we know x, we substitute x with 38 in the expression for the measure of angle M.
m<M = 3x - 16
m<M = 3(38) - 16
m<M = 114 - 16
m<M = 98

the sum of 12+12
12+12 is an even
number?
Answer:
An even number is a number that can be divided into two equal halves.
Also even numbers end in one of these digits: 0, 2, 4, 6, or 8
12 + 12 + 12 + 12 = 48
48 with the digit 8
48 divided in half gives two equal halves:
48/2 = 24
The number 24 can be added twice to check that the answer is correct:
24 + 24 = 48
So to summarize:
The sum of 12 + 12 + 12 + 12 is an even number because it can be equally divided in two halves and it ends in the digit 8.

Xavier can work no more than 40 hours in a week. He has already worked 24 hours this week. What is the maximum number of 8-hour days Xavier can work for the rest of the week?
Answer:
He can work a maximum of 2 8-hour days for the remainder of the week
Step-by-step explanation:
Firstly, from the question, we are made to know that the maximum work hours is 40 hours.
Now, we know that he has already worked 24 hours this week, the number of hours remains to work will be 40-24 = 16 hours
Now, given that his working hour is 8-hours per day, we want to know the number of days he has to work for the remainder of the week
Mathematically, that would be 16 hours divided by 8-hours days
That is 16/8 = 2

Johnathan picked colored beads from a jar 50 times, replacing the bead each time. He picked a red bead 12 times, a yellow bead 14 times, and a blue bead 24 times. How many blue beads should Johnathan expect to pick out of 150 times?
Answer: 72 beads
Step-by-step explanation:
From the question, we have the information that Johnathan picked colored beads from a jar 50 times and replaced the bead each time. Jonathan picked a red bead 12 times, yellow bead 14 times, and a blue bead 24 times.
Out of 50 picks, the following beads were picked:
Red = 12
Yellow = 14
Blue = 24
Total = 50
Fraction of blue bead = 24/50 × 100
= 48%
The blue beads that Johnathan will pick out of 150 beads will be:
= 48% of 150
= 48/100 × 150
= 0.48 × 150
= 72 blue beads
Jonathan will pick 72 blue beads out of 150 beads.
Answer:
72 beads

The length of a rectangular swimming pool is p m and its width is q m. It is given that the length of the swimming pool is twice its width. If the perimeter of the swimming pool is 150 m, find the values of p and q.
(**please use the simultaneous linear equations in two variables to solve this question)
**if you have answer this question I will choose you to be the brainlest answer**
Answer: q = 25 m, p = 50 m
Step-by-step explanation:
p is the length, and q is the width.Since the length is twice as long as the width, we can come up with the equation: p = 2qSince the perimeter is 150, we can also come up with this formula since the perimeter is all sides added together: 2p + 2q = 150Since we have two equations, we can just plug them into each other. First, let's substitute the 2q in the second equation with p that is defined in the first equation: 2p + p = 150If we simplify that, we get: 3p = 150Now we know that p = 50 m.Now, if you plug in 50 into the first equation you get: 50 = 2q.Next, just simplify, and you know that q = 25 m.Therefore, p = 50 m, q = 25 m.Can someone please help me???

what is the area of the triangle below?
Answer: 10
Step-by-step explanation:I like using this method:
Put a square which covers this triangle
Find the area of the rectangle which is 20
Half it which is 10
Now you have the area which is 10
Answer: The other answer is incorrect!
Step-by-step explanation:
An easier way is just imagine it being straight and not slanted. Counting the base its 3blocks and counting from the highest point all the way to the base its 4 blocks. Base=3 blocks and height=4 blocks. Substituting into the tirangle area formula which is b(h)/2 (base times height divided by 2).
You have 3x4=12.
Then 12/2=6 blocks
Therefore the area of the given triangle is 6 blocks squared (din)t forget the square).
The other answer is incorrect because this triangle is not half of this rectangle and in this question it’s just a grid (we have to use the grid)!

For every hour she earns 12$
The correct statement about the graph is for each hour Lisa earns $12. This can be obtained by studying the graph.
How do we compare the money earned to number of hours ?By observing the graph we can say that Earnings are directly proportional to Time.
Taking any point on the graph, for example (24,2) we can say that for 2 hours Lisa earns $24 ⇒ for 1 hour she earns $12 .
Hence the correct statement about the graph is for each hour Lisa earns $12.

solve for p
Answer:
p = - 5i or p = 5i
Step-by-step explanation:
Noting [tex]\sqrt{-1}[/tex] = i
Given
p² = - 25 ( take the square root of both sides )
p = ± [tex]\sqrt{-25}[/tex] = ± [tex]\sqrt{25(-1)}[/tex] = ± 5i
Thus
p = - 5i or p = 5i
Because p squared is equal to -25, the square root of -25 is equal to p.
Because of this, finding the square root of -25 will give us our answer.
[tex]\sqrt{-25}[/tex] = 5i
Therefore, p = 5i or p = [tex]\sqrt{-25}[/tex].
