The hyperbola has two vertices at (-2,0) and (2,0)
We have given that the equation
[tex]\frac{x^2}{4}-\frac{y^2}{9}=1[/tex]
What is the equation of the hyperbola?[tex]\frac{x^{2} }{a^2}+\frac{y^2}{b^2} =1[/tex]
Compare the above equation of the hyperbola with given equation
therefore a=2
vertices are (-a,0) and (a,0)
Therefore the vertices are (-2,0) and (2,0)
See the graph of the hyperbola in link given below.

Felipe is a software salesman. His base salary is $2200, and he makes an additional $70 for every copy of English is Fun he sells. Let P represent his total pay in dollars), and let N represent the number of copies of English is Fun he sells. Write an equation relating P to N. Then use this equation to find his total pay if he sells 26 copies of English is Fun.
Multiplying N by what he makes for each one and add to his salary:
P = 70N + 2200
Replace n with 26 and solve:
P = 70(26) + 2200
P = 1820 + 2200
P = 4020
He earns $4,020
Answer:

The circumference of a circle is about 50 centimeters (cm). Which is closest to the length of its radius? You may use 3.14 for
Α.4 cm
B. 8 cm
C.16 cm
D.32 cm
Answer:
8 cm
Step-by-step explanation:
The formula of circumference is c= πd------(1)
where C = circumference, π = 3.14 and d = diameter
as we know that diameter is equal to d= 2r
put the diameter formula in eq(1)
we get c= π2r-------(2)
from eq (2) separate r means radius
hence, r= c/(π2)------(3)
put the values in eq(3)
and radius is equal to 8 cm.

Persephone and Madison are sharing a coloring book with 48 pages in it. Persephone can color one page in 8 minutes. Madison can color one page in 6 minutes. They color every page in the book.
Answer:
[tex]Persephone = 27\frac{3}{7}[/tex]
[tex]Madison = 20\frac{4}{7}[/tex]
Step-by-step explanation:
Given
[tex]Pages = 48[/tex]
[tex]P=8\ mins[/tex] --- Persephone
[tex]M = 6\ mins[/tex] --- Madison
The question is incomplete, however a possible question could be:
To determine the number of pages colored by each of them
First, we determine the ratio of time spent by each:
[tex]P : M = 8 : 6[/tex]
The number of pages covered by Persephone is:
[tex]Persephone = \frac{P}{P + M} * Pages[/tex]
[tex]Persephone = \frac{8}{8+6} * 48[/tex]
[tex]Persephone = \frac{8}{14} * 48[/tex]
[tex]Persephone = \frac{384}{14}[/tex]
Simplify
[tex]Persephone = 27\frac{3}{7}[/tex]
This implies that Madison colors the remaining pages.
This is calculated as:
[tex]Madison = Pages - Persephone[/tex]
[tex]Madison = 48 - \frac{384}{14}[/tex]
Take LCM
[tex]Madison = \frac{48 * 14 - 384}{14}[/tex]
[tex]Madison = \frac{288}{14}[/tex]
Simplify
[tex]Madison = 20\frac{4}{7}[/tex]
A dresser has a width of 6 feet, a height of 3 feet, and a depth of 2 feet. If the dresser has 6 drawers of the same size, what is the volume of the space for each drawer?
Answer:
The volume of the space for each drawer is 6 feet^3.
Step-by-step explanation:
Solve for the volume of the entire dresser.
Formula for volume of a rectangle:
Volume (v) = Length (l) × width (w) × height (h)
v = 2 × 6 × 3
v = 12 × 3
v = 36
Now divide the volume by the number of drawers.
36 ÷ 6 = 6

Consider the equation of parabola y = 5x - 30x + 45.
Its vertex is located at
( , )
Answer:
(3, 0 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c (a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 5x² - 30x + 45 ← is in standard form
with a = 5, b = - 30 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{-30}{10}[/tex] = 3
Substitute x = 3 into the function for corresponding value of y
y = 5(3)² - 30(3) + 45 = 45 - 90 + 45 = 0
vertex = (3, 0 )
Answer:
Vertex is (3,0)
Step-by-step explanation:
Given y= 5x^2 - 30x + 45
y = 5 ( x^2 - 6x + 9)
= 5 ( x -3 )^ 2 + 0
Standard formula of parabola is y = a(x - k)^2 + k where vertex is (h,k)
Here, h = 3 and k = 0
So, Vertex is ( 3, 0)

when finding the area of a trapezium you can also just split the rectangle and triangle to have 2 different areas then combine to have the same area. but also this would be more difficult if you needed to separate the trapezium into more than 3 shapes.
so if there is like a trapezoid that you split and there is a rectangle and 2 triangles it is harder than doing the formula.
so use the formula sometimes too if it is easier.
Answer:
1 would be 45, 2 would be 32, 3 would be 35, 4 would be 32

the circumference of a circle is about 48.042 yards. the circle's diameter is ___ yards.
use 3.14 for pi.
Step-by-step explanation:
Given
Circumference of circle = 48.042 yards
diameter (d) = ?
we know
Circumference = πd
or, 48.042 = 3.14 * d
or, d = 48.042 / 3.14
Therefore d = 15.3 yards
The circle's diameter is 15.3 yards.

Some to do. So do it.
Answer:
1. A=42
L=14
42=W(14)
divide both sides by 14
3=W
2. A=96
L=12
96=W(12)
divide both sides by 12
8=W
3. A=90
L=18
90=W(18)
divide both sides by 18
5=W
4. A=1.50
L=15
1.50=W(15)
divide both sides by 15
0.1=W

Parallelogram Properties - Angles
Answer: x=30°
Step-by-step explanation:
A parallelogram always add up to 360°.
Opposite angles like F and H are always the same, so H=150°.
150+150=300 (what angles F and H add up to)
So we can do:
360-300=60
Now we know that the angle x and E have to add up to 60 but still be the same, so x will equal 30°.
We can check this by adding up all of the sides:
150+150+30+30=360°
Hope this helped :)
