17.83 times 1.1
=19.613
17.83+19.613
=37.443
=37.5 dollars
Answer:
a) Option A: r = 5
b) Option C: y = x
Step-by-step explanation:
a) First, we know that a circle centered at the origin of radius R is written as:
x^2 + y^2 = R^2
Then x^2+y^2=25 can be rewritten as:
x^2 + y^2 = 5^2
This is a circle of radius 5.
Then in polar form, this can be written as:
r = 5
b) Now we have the angle 225°
For rectangular coordinates (x, y)
The correspondent value of θ is given by:
Tan(θ) = y/x
In this case, we have θ = 225°
Then:
Tan(225°) = 1 = y/x
This can be rewritten as x = y
Then the correct option is C) y = x
Answer:
A and D
Step-by-step explanation:
A. - 10 + 8 = -2
B. 10 + -8 = 10 -8 = 2
C. -10 + - 8 = -10 - 8 = -18
D. 8 + - 10 = 8 - 10 = -2
E. 10 + 8 = 18
It is given in the question that the formula of volume of cone is
Where V is the volume, r is the radius and h is the height.
And we have to find an expression for h.
First we multiply both sides by 3, and on doing that we will get
Now to isolate h, we have to get rid of pi r square by dividing.
Therefore the correct option is B.
Answer:
Step-by-step explanation:
If the 2 lines are parallel
then x = 70 cos ( alternate interior angle)
but if not sorry man I just in grade 9 its my best effort
Really sorry. <3
