What's the slope and y-intercept of the equation 3x + 4y = 8? A) m = –3∕4; b = 2 B) m = –4; b = 3 C) m = 3∕4; b = –2 D) m = –3; b = –4
Answer:
A) m = –3∕4; b = 2Step-by-step explanation:
The slope-intercept form is
y = mx + b, where m- slope, b- y-interceptConvert the given equation into slope-intercept form
3x + 4y = 84y = - 3x + 8y = - 3/4x + 2The slope is:
m = - 3/4The y-intercept is:
b = 2Correct choice is A
First isolate y
3x+4y=84y=-3x+8y=-3/4x+8/4y=-3/4x+2Compare to slope intercept form y=mx+b
Slope=m=-3/4y intercept=b=2Give an example of dimensions of a pyramid that would result in a volume of 36 cubic units.
Answer:
Step-by-step explanation:
Dimensions: 1 x 1 x 36 or 12 x 3 x 1 or 9 x 4 x 1 or 9 x 2 x 2
The dimensions of a pyramid are usually described in terms of its base and height. The base of a pyramid is the polygonal shape at the bottom of the pyramid, and the height is the perpendicular distance from the base to the apex.
How to find the dimensions of a pyramid?To find the dimensions of a pyramid with a volume of 36 cubic units, we need to use the formula for the volume of a pyramid:
Volume of a pyramid = (1/3) x Base area x Height
Let's assume that the base of the pyramid is a square with sides of length "a". Therefore, the base area of the pyramid is a x a = a^2.
Now, we can substitute the given volume of 36 cubic units into the formula:
36 = (1/3) x a^2 x h
Multiplying both sides by 3 and dividing by a^2, we get:
h = 108/a^2
So, the height of the pyramid is equal to 108 divided by the square of the length of one side of the base.
We can choose any value for "a" and calculate the corresponding value of "h" that will result in a volume of 36 cubic units.
For example, if we choose "a" to be 3 units, we get:
h = 108/3^2 = 12 units
Therefore, the dimensions of the pyramid are:
Base: 3 units x 3 units
Height: 12 units
Checking the volume using the formula, we get:
Volume of the pyramid = (1/3) x 3^2 x 12
Volume of the pyramid = 36 cubic units
So, a pyramid with a base of 3 units by 3 units and a height of 12 units would have a volume of 36 cubic units.

Sketch the graph of y=x^2-4x+3
Answer:
see attached graph
Step-by-step explanation:
Given equation: [tex]y=x^2-4x+3[/tex]
Standard form of a quadratic equation: [tex]y=ax^2+bx+c[/tex]
where [tex]c[/tex] is the y-intercept
If [tex]a > 0[/tex] then the parabola opens upwards.
If [tex]a < 0[/tex] then the parabola opens downwards.
Therefore, the y-intercept of the graph is (0, 3)
To find the x-intercepts, factor the equation:
[tex]y=x^2-4x+3[/tex]
[tex]\implies y=x^2-x-3x+3[/tex]
[tex]\implies y=x(x-1)-3(x-1)[/tex]
[tex]\implies y=(x-3)(x-1)[/tex]
Therefore, the x-intercepts of the graph are (3, 0) and (1, 0)
To determine the vertex, differentiate the equation:
[tex]\implies \dfrac{dy}{dx}=2x-4[/tex]
Set to zero and solve for x:
[tex]2x-4=0 \implies x=2[/tex]
Substitute [tex]x=2[/tex] into the original equation and solve for y:
[tex]\implies y=(2)^2-4(2)+3=-1[/tex]
Therefore, the vertex (or turning point) is at (2, -1)

Examine the following piecewise function.
A graph formed of straight line segments between the following points: (negative 8, 3), (negative 2, 8), (2, 8), (3, 0), and (7, negative 7).
© 2018 StrongMind. Created using GeoGebra.
Which statements are true?
Select all that apply.
1.The function is increasing over the interval 2≤x≤3
2.The function is increasing over the interval 2≤x≤3.
3.The function is increasing over the interval −8≤x≤−2.
4.The function is increasing over the interval −8≤x≤−2.
By analyzing when the piecewise function increases and when it decreases, we can conclude that the true statement is:
"The function is increasing over the interval −8≤x≤−2."
Which statements are true?We know that our function is made of straight lines that connect:
Point (-8, 3) with (-2, 8) {This is an increasing line}Point (-2, 8) with (2, 8) {This is a horizontal line}Point (3, 0), and (7, -7) {This is a decreasing line}(to see if it increases or decreases, compare the y-value of the second and first point. If the second is larger, then the line increases).
Then the statement that is true is:
3) "The function is increasing over the interval −8≤x≤−2."

On a circle of radius 10 feet, what angle would subtend an arc of length 6 feet?
Answer:
34.38 (rounding to the nearest hundredth)
Step-by-step explanation:
I have my work linked below, but I used to arc length formula and plugged in all known numbers. Then solved for x which will be the angle you are looking for. Hope this helps!
On a circle of radius 10 feet, 34.37° angle would subtend an arc of length 6 feet.
How to find the length of an arc?The length of an arc formula is represented as follows
The length of arc = Ф / 360 × 2πr
where
Ф = angle, r = radius
It is given that circle of a radius of 10 feet,
The length of arc = 6 ft
Therefore,
6 = Ф / 360 × 2 × 3.14159 × 10
6 = 62.8318Ф / 360
360 x 6 = 62.8318Ф
Ф = 360 x 6 / 62.8318
Ф = 34.3784
Ф ≈ 34.37°
