vertex (-5,3) and passes through (-4,2)
The equation of the parabola that has a vertex at (-5,3) and passes through (-4,2) is y = [tex]-x^2-10x-22[/tex]
The vertex of the parabola = (-5,3)
Passing through the point = (-4,2)
The equation of the parabola in the vertex form y = [tex]a(x-h)^2+k[/tex]
(h,k) is the vertex of the parabola
h = -5
k = 3
Substitute the values in the equation
y = [tex]a(x+5)^2+3[/tex]
Here the parabola is passing through the point (-4,2)
Substitute this value in the equation and find the value of a
2 = [tex]a(-4+5)^2+3[/tex]
2 = a×1+3
2 = a+3
a = 2-3
a = -1
Then
y = [tex]-1(x+5)^2+3[/tex]
y = [tex]-1(x^2+10x+25)+3[/tex]
y = [tex]-x^2-10x-25+3[/tex]
y = [tex]-x^2-10x-22[/tex]
Hence, the equation of the parabola that has a vertex at (-5,3) and passes through (-4,2) is y = [tex]-x^2-10x-22[/tex]

Solve the right triangle shown in the figure. C. BC= 3.2m, B = 43.29, ZC = 90° a. ZA = 46.80, AC = 1.9m, AB = 3.7m b. ZA = 46.89, AC = 5.3m, AB = 4.4m - LA = 46.8°, AC = 5.3m, AB = 6.2m ZA = 46.8°, AC = 3.0m, AB = 4.4m d. -
The given triangle can be shown below
Since the sum of angles in a triangle is 180 degrees it follows
[tex]\angle A+\angle B+\angle C=180^{\degree}[/tex]It follows
[tex]\begin{gathered} \angle A+43.2+90=180^{\degree} \\ \angle A=180-90-43.2 \\ \angle A=46.8^{\degree} \end{gathered}[/tex]From the triangle above
Using trigonometrical ratios

The gravity is working. Energy-based items are affected by gravity. The vertical motion model, h = -16t2 + vt + s, where v is the initial velocity in feet/second and s is the height in feet, to calculate the maximum height of the ball.
Why is initial height important?The distance traveled in flight increases with release level. This is because the projectile will stay in the air longer if it is launched higher. The projectile will be under the influence of the horizontal component longer.
The beginning vertical velocity determines the maximum height. Increasing the launch angle raises the maximum height because steeper launch angles have a larger vertical velocity component.
Greater maximum height is associated with greater launch angles.
Greater relative projection height results in longer flight time, which increases horizontal displacement when projection speed is constant.

-1/2 is the slope of the line that passes through the points (12,-1) and (-2,6).
Slope is simply expressed as change in y over the change in x.
The slope formula is expressed as;
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Given the data in the question;
Point 1( 12, -1 )
x₁ = 12y₁ = -1Point 2( -2, 6 )
x₂ = -2y₂ = 6To determine the slope of the line, plug the given coordinates into the slope formula above.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Slope m = ( 6 - (-1) )/( -2 - 12 )
Slope m = ( 6 + 1) )/( -2 - 12 )
Slope m = ( 7 ) )/( -14)
Slope m = -7/14
Slope m = -1/2
Therefore, the slope of the line is -1/2.

What is the slope of the line that contains the points negative 3, negative seven halves and (2, −4)?
one fourth
one tenth
negative one tenth
negative one fourth
Answer:
0.7
Step-by-step explanation:
This question tests on the concept of slope or gradient of a line.
We know that the equation, m, for a slope =
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
We can identify 2 points from the question as (x1, y1) and (x2, y2) to solve for the gradient, and therefore they are:
(x1,y1) as (-3,-7.5)
(x2,y2) as (2,-4)
Now we can substitute these values in to solve for the slope.
[tex] \frac{ - 4 - ( - \frac{7}{2})}{2-(-3)} \\ = \frac{ - 4 + frac{7}{2}}{5} \\ = \frac{-0.5}{5} \\ = - \frac{1}{ 10} \\ = -0.1[/tex]

The equation of slope-intercept form is y = mx - m.
What is slope-intercept form?
A line's equation can be written in the slope-intercept form such that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are instantly visible. This form is commonly referred to as the y = mx + b form.from the graph points are ( 1 , 1 )
So, x = 1 & y = 1
Equation is y = mx + c
put the value (x, y)
1 = m * 1 + c
1 = m + c
c = - m
y = mx - m
the equation is y = mx - m

Which figure is the image of Figure 1 after a reflection over the y-axis and a translation 3 units down?
When we perform a reflection over the y-axis then the y-coordinates remain the same but the x-coordinates are inverted (opposite sign).
Example:
As you can see in the above figure, a reflection over the y-axis would look like this.
When we perform a translation of 3 units down then the shape gets shifted downwards by 3 units.

What are the different conditions when 2 line intersects?At most, 2 distinct lines will intersect at one point. The general form of the two equations is required in order to locate the intersection of two lines. Only non-parallel lines will cross with each other. A pair of scissors, a folding chair, a road cross, a signboard, and other everyday objects are typical examples of intersecting lines. We will learn in-depth instructions on how to locate the spot where two lines intersect in this mini-lesson. They are referred to as intersecting lines when two lines have exactly one point in common. A common point connects the intersecting lines. The point of intersection is also known as the common point that all intersecting lines share. There will be a point of intersection between the two coplanar, non-parallel straight lines.

What do you mean garbage?
Waste materials that are thrown by people under various names—garbage, trash, junk, or refuse—usually reflect a perception of their lack of utility. Typically, the word excludes poisonous wastes, body wastes, and wastes that are only liquid or gaseous. Garbage is frequently categorized and categoriszed into types of materials appropriate for particular types of disposal.
Lets assume an ideal situation in 6 months, 3 months will have 31 days and 3 months will have 30 days.
So, total days in 6 months = 3(30) + 3(31)
total days in 6 months = 183
A week contains 7 days:
So, total number of weeks = days in 6 months/7
total number of weeks = 183/7
total number of weeks = 26.14
So, the garbage collector gives service of 26 weeks in 6 months.
Since, he receives 80 each from 9 households in a week.
so, total earning in a week = 80(9) = 720
Total earning in 6 months = weeks in 6 months (earning of 1 week)
Total earning in 6 months = 26 (720)
Total earning in 6 months = 18,720

Answer:
Equation A has the larger y intercept.
Equation A has a y-intercept of 2
Equation B has a y intercept of -5
Step-by-step explanation:
Equation A is in the slope intercept form of a line.
y = mx + b. The number in the b place is the y-intercept.
y = 5x + 2. The 2 is in the intercept place so the y-intercept is 2.
Equation B is written in the standard form of a line.
5x + 4y = -20
If I let x = 0, I can solve for the y intercept.
5(0) + 4y = -20
4y = -20 Divide both sides by 4
y = -5
This would be point (0,-5). The y-intercept is always boing to be when x = 0.
