Answer:
The integer change is -450 cm^3
Step-by-step explanation:
Here, we want to write the integer of the change in the volume of a ballon when it loses 450 cm^3 of air
Losing this volume means we are subtracting 450 from the original volume
This represents a change of -450 cm^3
Which graph shape represents the polar curve r = 1 + 4sin(θ)?
a cardioid
a rose curve
a limaçon with an inner loop
a limaçon without an inner loop
Answer:
A cardioid
Step-by-step explanation:
A cardioid is a curve in the shape of a heart traced by a point on the circumference of a circle as it rolls around a fixed circle of the same radius.
The equation of vertical cardioid is [tex]r=a[/tex] ± [tex]a\sin \theta[/tex]
Given the polar curve is [tex]r=[/tex] [tex]1+[/tex] 4 [tex]\sin \theta[/tex]
This is an equation of vertical cardioid.
So, it represents a cardioid.
Answer:
C - a limaçon with an inner loop
Step-by-step explanation:
If you have a graphing calculator, use it to plug in the equation.
Based on what you have learned, you will recognize the graph is C

Evaluate the expression. 7 + 8 x 4 - 6 ÷ 2
Answer:
36
Step-by-step explanation:
PEMDAS
7+(8)(4)-6/2
Answer:
36
Step-by-step explanation:
7+ 8 * 4-6/ 2
7 + 8( 8*4) - (6/2)
Multiple: 8 * 4 = 32
Add: = 7 + 32 = 39
Divide: 6 / 2 = 3
Subtract: 39 - 3 = 36

Solve for side BA
(show your work)
Answer:
BA = 25.5961
Step-by-step explanation:
To solve for side BA, we need to use the correct trigonometric function that relates (from the perspective of angle B) side AC and BA.
AC is Opposite of angle B
BA is the Hypotenuse
The function we use here is Sine. Sine is:
Sin(θ) = Opposite/Hypotenuse
So we simply substitute our information to solve.
Sin(62) = 22.6/BA
BA = 22.6/Sin(62)
Typing this into our calculator we get:
BA = 25.5961
(This is rounded to 4 decimal places)
whats the solution
Answer:
Step-by-step explanation:
To find the center and the radius, we need to put the equation in the (x-a)^2+(y-b)^2=r^2 [a is the x-coordinate, b is the y-coordinate, and r is the radius].
(x+6)^2+(y+7)^2 - 36 - 49 + 69 = 0
(x+6)^2+(y+7)^2 - 16 = 0
(x+6)^2+(y+7)^2 = 16
(x+6)^2+(y+7)^2 = 4^2
The center is (-6,-7) and the radius is 4.

What is the solution to 0.3(12x - 16) = 0.4(12 - 3x)?
Step-by-step explanation:
The solution is one-solution
.3(12x-16)=.4(12-3x) (you do the distributive property)
3.6x-4.8=4.8-.12x (you add 1.2 to both sides)
3.6x-3.6=4.8 (You add 3.6 to both sides)
3.6x=8.4 ( You divide 3.6 both numbers)
x=0.4285...
Its a one-solution
