Answer:
The parabola is a horizontal parabola and it faces to the right. The vertex is at (3, -3) (*Double check this because I don't have graph paper*) because the vertex is always the same distance from the directrix and the focus.

Write a simplified polynomial expression in standard form to represent the area of the rectangle below: A picture of a rectangle is shown with one side labeled as 2 x minus 2 and another side labeled as x plus 4. 2x2 3x − 20 2x2 13x − 1 2x2 13x − 20 2x2 3x − 1.
The Simplified polynomial expression in the standard form which represents the area of the given rectangle is,
[tex]2x^2+6x-8[/tex]
What is area of rectangle?The area of rectangle is the product of its length and width. It can be given as,
[tex]A=a\times b[/tex]
Here, (a) is the length of the rectangle and (b) is the width of the rectangle.
Given information-
One side of the rectangle is labeled as 2x-2.
Another side of the rectangle is labeled as x+4.
The image of the rectangle is attached below.
Let (l) is the length of the rectangle and (w) is the width of the rectangle.
In the below image, the length of the rectangle is,
[tex]l=4x+2[/tex]
The width of the rectangle is,
[tex]w=2x-2[/tex]
The area of the rectangle is the product of its length and width. Thus the area of the given rectangle is,
[tex]A=l\times w\\[/tex]
Put the values in the above expression as,
[tex]A=(x+4)\times(2x-2)\\A=2x^2+8x-2x-8\\A=2x^2+6x-8[/tex]
Thus the area of rectangle in simplified polynomial expression in the standard form is,
[tex]2x^2+6x-8[/tex]

Alexa put $850 into savings account that earns 0.75% annual simple interest. If Alexa doesn’t make any deposits or withdrawals for 18 months, how much money will be in her account?
Principal= 850
rate = 0.75%
period = 18months
interest = 850x0.75%x18
= 850x0.0075x18
= 114.75
amount after 18 months
= 850+114.75 = $964.75

Write an equation for the line in point-slope form and then convert it to standard form. through (2, 3) and (3,5)
Answer:
equation of the line: 2x - y = 1
Step-by-step explanation:
Given coordinates: (2, 3) and (3,5)
find slope of the equation:
[tex]\frac{y2-y1}{x2-x1}[/tex]using the formula:
→ [tex]\frac{5-3}{3-2}[/tex]
→ [tex]2\\[/tex] .............this is slope, also refereed as (m) in short form.
using the equation formula:
y - y1 = m ( x - x1 )using the formula:
→ y - 3 = 2 ( x - 2 )
→ y - 3 = 2x - 4
→ y = 2x -4 +3
→ y = 2x - 1
→ -2x + y = -1
→ (-2x + y)/-1 = -1 /-1 [ divide both sides by -1 ]
→ 2x - y = 1 .......final answer in standard form where ( Ax + By = C ) where "A" should be positive and "C" constant on the right hand side.

Answer:
a) rise 5, run 5, slope 1
b) rise 10, run 5, slope 2
Step-by-step explanation:
The rise is the vertical difference between the points. It is the length of the vertical side of the triangle you have drawn. You can determine that length by counting grid squares or by finding the difference of the y-coordinates of the points.
The run is the horizontal difference between the points. It is the length of the horizontal side of the triangle you have drawn. You can determine that length by counting grid squares or by finding the difference of the x-coordinates of the points.
a)rise = 5; run = 5. (counting grid squares)
slope = rise/run = 5/5 = 1
__
b)rise = 10; run = 5. (taking coordinate differences: 5-(-5) = 10; 4-(-1) = 5)
slope = rise/run = 10/5 = 2

What is the equation of the line that passes through the point (3,5) and has a slope of 2?
Answer:
y=2x-1
Step-by-step explanation:
The equation for a line (slope-intercept form) is:
y=mx+b
m: slope
b: y-intercept
x and y: (x, y) coordinate pair
In this scenario, since we are given the slope and a point on the line, we can solve for the y-intercept:
y=2x+b
5=2(3)+b
5=6+b
Subtract 6 from both sides
b=-1
Therefore the equation of the line is:
y=2x-1

Old MacDonald had a farm with some raspberry bushes. During the summer 5 of the bushes died from the heat. Each bush produces 6 pounds of raspberries in the fall. MacDonald gathered 96 pounds of raspberries that fall. How many bushes did he have before summer?
Answer:
21
Step-by-step explanation:
5 bushes ×6 pounds is =30 pounds
30pounds + 96pounds = 126pounds
126pounds ÷6 = 21bushes

Answer:
LCM: 60
HCF: 10
Step-by-step explanation:
Listing Multiples
LCM:
Multiples of 20:
20, 40, 60, 80, 100
Multiples of 30:
30, 60, 90, 120
Therefore,
LCM(20, 30) = 60
----------------------------------------
Factorization
HCF:
The factors of 20 are: 1, 2, 4, 5, 10, 20
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30
Then the greatest common factor is 10

Answer:
A) [tex]\frac{1+sin(x)+1-sin(x)}{1-sin^2(x)}=\frac{2}{cos^2(x)}[/tex]
Step-by-step explanation:
By combining the fractions on the left side into one fraction, we have:
[tex]\frac{1}{1-sin(x)}+\frac{1}{1+sin(x)}=\frac{2}{cos^2(x)}\\ \\\frac{1+sin(x)+1-sin(x)}{(1-sin(x))(1+sin(x))}=\frac{2}{cos^2(x)}\\\\\frac{1+sin(x)+1-sin(x)}{1-sin^2(x)}=\frac{2}{cos^2(x)}[/tex]
Also, given the Pythagorean Identity [tex]sin^2(x)+cos^2(x)=1[/tex], then [tex]cos^2(x)=1-sin^2(x)[/tex].
