What is the slope-intercept formula?
Answer:
To find slope intercept, you must use the substitute term for slope, m, and then use the following equation. ↓
[tex](y = mx+b)[/tex]
Next, you want to use these terms to help you solve for b. ↓
[tex]Slope = m\\Points = x, y\\y-intercept = b[/tex]
Answer:
y=mx+b
Step-by-step explanation:
The slope intercept form is y=mx+b
M = slope
B = y-intecept
and when you substitue the numbers for the variables then you have it in slope-intercept formula

It is a solid shape that contains lateral surface and two circular bases which are parallel and congruent.
A. cube
B. cylinder
C. sphere
D. cone
Answer:
B (cylinder)
Step-by-step explanation:
Two circular bases which are parallel and congruent :
This basically means that the shape contains a circular base (supposedly the bottom), but since it has two bases, its on the top and the bottom. Because it's congruent, the bases are both equal in shape and size. It is also parallel as well, in which the bases have the same distance between them.
The cube doesn't have any circular bases.
The sphere doesn't have any faces, nor edges.
A cone has a circular base, but it doesn't have two.
A cylinder has two circular bases, as well as they are parallel and congruent.
So, your answer is B (cylinder).
Hope this helped !

The
value of f(x) = –|x – 4| – 5 is
when x =
.
The
value of f(x) = x2 – 2x + 1 is
when x =
.
Answer:
First problem: max when x = 4
Second problem: min when x = 1
Step-by-step explanation:
The graph of f(x) = –|x – 4| – 5 is a translation of that of g(x) = -|x|. The vertex of the latter is (0, 0). First this must be translated 4 units to the right and then the resulting graph 5 units downward. The vertex of this translation is (4, -5). Since this graph opens downward, this (4, -5) is the maximum function value, that is, when x = 4.
The graph of f(x) = x2 – 2x + 1, or (better yet) f(x) = x^2 – 2x + 1, or
f(x) = (x - 1)^2 + 0, is that of a parabola that opens upward and has its minimum at x = 1, or (1, 0).

A scale model of a large, three-dimensional “real world” object uses a scale of 0.5 in. = 50 ft.
Fred was only able to measure the model using metric units. He measured the length of the model as 372.5 mm.
Fred knows that 1 inch = 2.54 cm and that 1 cm = 10 mm.
What is the approximate length of the actual “real world” object?
A.
244.3 ft
B.
122.2 ft
C.
2,932 ft
D.
1,467 ft
The approximate length of the actual object is 1465 ft, which is closest to option D.
What is a scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
First, let's convert the length of the model from millimeters to inches:
372.5 mm = 372.5/10 cm = 37.25/2.54 in ≈ 14.65 in
Next, we can use the scale of the model to find the length of the actual object in feet:
0.5 in. = 50 ft.
So, 1 in. = 100 ft.
Therefore, the length of the actual object in feet is:
14.65 in x (100 ft/in) = 1465 ft
Therefore, the closest length is 1467 feet.

If f(x) is a linear function such that f(2)= 5 and f(4) = 13, f(x) = ?
A) 3x - 4
B) 4x - 3
C) 4x + 3
D) 1/4x + 9/2
Answer: you are on your own.
Step-by-step explanation:
The equation of the linear function f(x) is f(x) = 4x - 3. So, the answer is B) 4x - 3.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
We can use the two given data points to determine the equation of the linear function f(x) using the slope-intercept form:
f(x) = mx + b
where m is the slope and b is the y-intercept.
First, we can find the slope of the function by using the formula:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (2, 5) and (x₂, y₂) = (4, 13)
m = (13 - 5) / (4 - 2) = 4
Now we can use the slope and one of the given points to solve for the y-intercept:
5 = 4(2) + b
b = -3
Therefore, the equation of the linear function f(x) is f(x) = 4x - 3.

What is the recursive rule?
Question 2 options:
an = an+1 + 500; a1 = 30,000
an = an−1 + 30,000; a1 = 500
an = an−1 + 500; a1 = 29,500
an = an−1 + 500; a1 = 30,000
Mr. Red's salary is an illustration of an arithmetic sequence
The recursive rule of the sequence is (d) an = an−1 + 500; a1 = 30000
How to determine the recursive formula?From the complete question, we have the explicit rule of Mr. Red's salary to be
an = 500n + 29500
Where:
First term, a1 = 30000Common difference, d = 500The above means that:
The difference between a term and the next term is 500.
So, the recursive rule is:
an = an−1 + 500
Recall that:
a1 = 30000
Hence, the recursive rule of the sequence is (d) an = an−1 + 500; a1 = 30000

what is the angle of elevation of the sun when the shadow of a pole of 18m high is 6√3m long? ( i need step by step explanation pls I'm having a class test tmr pls help)
Answer:
See diagram below
Step-by-step explanation:
arctan (angle ) = 18 / (6 sqrt3) = 60 degrees
Step-by-step explanation:
height of pole = 18m = p
length of shadow = 6[tex]\sqrt{3}[/tex] m = b
now,
tan α = p/b
= 18/6[tex]\sqrt{3}[/tex]
= [tex]\sqrt{3}[/tex]
or, tan α = tan 60
α = 60
Therefore angle of elevation of the sun is 60.

A buoy starts at a height of 0 in relation to sea level and then goes up. its maximum displacement in either direction is 6 feet, and the time it takes to go from its highest point to its lowest point is 4 seconds. which of the following equations can be used to model h, the height in feet of the buoy in relation to sea level as a function of time, t, in seconds? h = 4 sine (startfraction pi over 6 endfraction t) h = 4 sine (startfraction pi over 3 endfraction t) h = 6 sine (startfraction pi over 4 endfraction t) h = 6 sine (startfraction pi over 2 endfraction t)
The equation of the model h will be h = 6 × sin(2πt/8). Then the correct option is C.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
A buoy starts at a height of 0 in relation to sea level and then goes up.
Its maximum displacement in either direction is 6 feet, and the time it takes to go from its highest point to its lowest point is 4 seconds.
Then we have
[tex]h=A \times \sin \omega t, \ \ at=0, \ \ h =0[/tex]
The maximum displacement of the buoy in either direction is 6 ft, then we have
[tex]h=6 \times \sin \omega t[/tex]
The time it takes the buoy to get from the lowest to the highest point is 4 seconds then the oscillation time period will be 8 seconds.
Then we have
[tex]\omega T = 2\pi\\\\\omega = \dfrac{2\pi}{8}[/tex]
Then the h will be given as
[tex]h =6\times \sin (\dfrac{2\pi}{8}t)[/tex]

A dragon flew 300 miles from his castle to visit a friend. Flying with the wind, his trip took 2 hours. His return trip against the wind took 3 hours. What was the speed of the wind and the speed of the dragon in still air?
Please help me. I WILL mark brainliest and give lots of points.
Answer:I’m not sure about the wind but the speed of the dragon is 125mph
Step-by-step explanation:Remember,
Speed=Distance/Time
Distance=Speed x Time
Time=Distance/Speed
Knowing that the distance in both trips was the same, we can say that he flew his trip 150mph (Speed=300/2) the first time and 100mph (Speed=300/3) the second time. Next, we find the average of 150 and 100 and that is (100+150)/2 which is 125. I’m sorry I couldn’t find the speed of wind, but in my defense, I’m only in 6th grade. Hopefully that helped you, good luck!
