Answer:
4
Step-by-step explanation:
The slope of the line is given. It is 4. Use the equation y=mx+b to answer the other questions.
Substitute 1 in for y, 4 in for m, and 2 in for x and solve for b. The equation would look like 1=4(2)+b.
Solving that equation will give you b=-7
That means the y-intercept is -7.
The equation would then be y=4x-7
(a+b)²= ?

What is the domain of the function
Answer:
[tex]x\geq -6[/tex]
Step-by-step explanation:
The domain of a function is all of the values that [tex]x[/tex] can be under that specific function. In this case, we're asking what values of [tex]x[/tex] allow [tex]\sqrt{\frac{1}{3} x+2}[/tex] to exist.
In order for square roots to exist, the quantity under the square root must be greater than or equal to [tex]0[/tex], because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for [tex]x[/tex]:
[tex]\frac{1}{3}x+2\geq 0[/tex]
Solving this inequality, we get:
[tex]\frac{1}{3}x+2\geq 0[/tex]
[tex]\frac{1}{3}x\geq -2[/tex] (Subtract [tex]2[/tex] from both sides of the inequality to isolate [tex]x[/tex])
[tex]x\geq -6[/tex] (Multiply both sides of the inequality by [tex]3[/tex] to get rid of [tex]x[/tex]'s coefficient)
Hope this helps!

Step-by-step explanation:
Consider the polynomial function h(x) = -2x^5+ 8x^4
2x^2+15.
What is the end behavior of the graph of h ?
Answer: B
Step-by-step explanation:
Applying limits, it is found that the end behavior of the graph is:
B. As [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex], and as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex].
The function is:
[tex]h(x) = -2x^5 + 8x^4 - 2x^2 + 15[/tex]
To find the end behavior, we apply the limits as x goes to infinity, in which just the term with the highest exponent is considered, hence:
[tex]\lim_{x \rightarrow -\infty} h(x) = \lim_{x \rightarrow -\infty} -2x^{5} = -2(-\infty)^5 = -2(-\infty) = \infty[/tex]
Then, as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex]
[tex]\lim_{x \rightarrow \infty} h(x) = \lim_{x \rightarrow \infty} -2x^{5} = -2(\infty)^5 = -2(\infty) = -\infty[/tex]
Then, as [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex]
Hence, option B is correct.

What happens when the y-intercept is greater than 1?
What happens when the y-intercept is less than 1?
Answer:What happens when the y-intercept is greater than 1?: more than one y-intercept would violate this, since it would mean that there are two outputs for x=0. Therefore, it is not possible for a function to have more than one y-intercept. This function never crosses the y-axis because, since you can't divide by zero, it is undefined at x=0.
Step-by-step explanation:
9514 1404 393
Answer:
The graph intersects the y-axis above the point (0, 1)The graph intersects the y-axis below the point (0, 1)Step-by-step explanation:
Nothing special happens when the y-intercept is above or below the value of 1. The y-intercept is where the function's graph intersects the y-axis.
When the y-intercept is greater than 1, the graph intersects the y-axis above the point (0, 1).
When the y-intercept is less than 1, the graph intersects the y-axis below the point (0, 1).
__
The meaning of the y-intercept will depend on what the graph is modeling. No information about that is provided here.

There’s 18 boys and 11 girls in a class, they make a team with 7 students
a) in how many ways can they pick a team
b) how many teams can they get knowing there is 4 boys in each one?
"The number of boys is 45 the number of girls,"
or to say,
"The ratio of the number of boys to the number of girls is 45:1."
This second interpretation reflects the fact that 45 is the unit rate (which is a number) for the ratio 4:5.

The grades on a math midterm at Springer are roughly symmetric with \mu = 78μ=78mu, equals, 78 and \sigma = 5.0σ=5.0sigma, equals, 5, point, 0. Omar scored 646464 on the exam. Find the z-score for Omar's exam grade. Round to two decimal places.
Answer:
-2.8
Step-by-step explanation:
Given that:
Mean, μ = 78
Standard deviation, σ = 5
Omar's score, x = 64
The Zscore of Omar's score :
Zscore = (x - μ) ÷ σ
Zscore = (64 - 78) / 5
Zscore = - 14 / 5
Zscore = - 2.8
Hence, Omar's exam score is - 2.8
Answer:
-2.8 is correct

12. Solomon scored 88% on his math test. If the test had 25 questions total, how many
questions did Solomon miss?
Answer:
He missed 3 questions (which is a score of 22/25 that equals 88%)
Step-by-step explanation:
This is just what I've taught to judge this by "eye level" how to solve questions like these. In this case, since it's a 25 question test, if you divide 25/100 that means each question was 4 points.
So if 20/25 is 80% and 25/25 is 100%, so the answer is between that range.
Hope it helps.

A comet passes Earth every 70 years. Another comet passes Earth
every 75 years. If both comets pass Earth this year, how many years
will it be before they both pass Earth on the same year again?
Answer:
1,050 years
Step-by-step explanation:
A comet passes Earth every 70 years.
Another comet passes Earth
every 75 years
If both comets pass Earth this year, how many years
will it be before they both pass Earth on the same year again?
Find the lowest common multiple of 70 years and 75 years
70 years = 70, 140, 210 , 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260,
75 years = 75, 150, 225 , 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200, 1275, 1350
Lowest common multiple of 70 years and 75 years is 1,050 years
Therefore,
If both comets pass Earth this year, they both pass Earth the same year again in the next 1,050 years

The fishbowl is shaped like a sphere the fishbowl has a diameter of 16 what is the closest value of water in the Fishbowl and cubic inches
Answer:
2144.66 cubic inches
Step-by-step explanation:
The fishbowl is shaped like a sphere the fishbowl has a diameter of 16.
What is the closest value of water in the Fishbowl in cubic inches?
From the any question, we were told to find the closest value of the water in the fishbowl in cubic inches.
This means we are to find the volume.
The volume of a sphere is given as:
4/3πr³
We are given Diameter of the fish bowl = 16 inches
Radius = Diameter/2 = 16 inches/2
= 8 inches
Hence,
Volume of the sphere (Volume of water) = 4/3 × π × 8³
= 2144.66 cubic inches

You and a friend go to surf taco for lunch. you order 3 soft tacos and 2 burritos and your total bill is 25. Your friend bill is 30 for 5 soft tacos and 2 burritos. How much do soft tacos cost? 3x+2y=25 4x+2y=30 X-soft tacos y-burritos
Answer:
Step-by-step explanation:
Let the cost of one soft taco = s
Let the cost of one burrito = b
So we have this system
3s + 3b = 11.25
4s + 2b = 10.00 (1)
Divide the first equation through by 3 and we have that
s + b = 3.75 subtract b from both sides
s = 3.75 - b (2)
Sub (2) into (1) and we have
4 (3.75 - b) + 2b = 10.00 simplify
15 - 4b + 2b = 10.00
-2b + 15 =10.00 subtract 15 from both sides
-2b = - 5.00 divide both sides by -2
b = 2.50
And using (2)
s = 3.75 - 2.50 = 1.50
So... a soft taco 1.50 and a burrito is 2.50

3(p + 45)

Od
3(p + 5)
Answer:
um, I am confused on the answer options, but 3(p+5) is equivalent
Step-by-step explanation:
3p+15 is the same a 3(p+5) because in 3(p+5) we have to use the distribution property
So, it is 3p +15 here's a picture to explain it better
(3(p+45) would be too big of a number as you also use the distribution property and it would be 3p+135)
In Sichuan, China, Bernards stands at the top of the Jinping-1 dam and measures the angle of depression down to where Benjamin is standing at 1999 feet from the base of the dam. If the angle of depression is 26.6 degrees, how tall is the dam? Round to the nearest foot.
Answer:
This illustrates a right triangle.
Given:
a(height) = 2457 ft.
∠A = 22°23' ; which is the elevation and reflects the a(height)
Find:
b(base)
Solution:
Using the law of cosine, specifically tan∠ = opposite side÷adjacent side
By analysis, tan∠A = a÷b
Since we are finding b, the formula will be derived into:
b = a÷tan∠A
Find b(base):
b = 2457 ft. ÷ tan22°23' ; substituting the numbers
b ≈ 5,966.05 ft. ; Final Answer
