Answer:
Step-by-step explanation:
We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is 
.
Because all the angles of a triangle sum to 
, we have that 
.
We combine like terms on the left side to get 
.
We subtract 
on both sides to get 
.
So, 
and we're done!
Answer:
none of the given options is true
Step-by-step explanation:
Given: u=(-8,8) , v= (-1,2)
To find: vectors 
such that 
Solution:
A vector is a quantity that has both magnitude and direction.
Let 
So,
So, u = 
So, none of the given options is true
<span>The possible price of the magazine can be either $ 9 , $ 6 , or $3
First we need to understand the different between a cost and a price. A cost is the amount of money needed to Produce the magazine, while a price is the amount of money that the sellers get when he hand it over to customer
since its said the cost is in multiple of $ 3 , the possible price of two magazine would be :
$ 9 + $3 = $ 12
$6 + $6 = $ 12
$3 + $ 9 = $ 12</span>
(x+3)(5x-4)(2x-1)
multiply the first two by foil method
F x × 5x =5x²
O -4 × x =-4x
I 3 x 5x =15x
L 3 × -4 =-12
(5x²+11x-12)(2x-1) distribute
2x(5x²+11x-12)=10x³+22x²-24x
-1(5x²+11x-12)=-5x²-11x+12
combine like terms
10x³+22x²-5x²-24x-11x+12
Answer: 10x³+17x²-35x+12
Answer:
20
Step-by-step explanation:
To find the diameter of a circle (that you know the circumference of), you use a formula.
The formula is: C=πd
variables:
C = circumference
d = diameter
You do not know the diameter, so this is the variable that you are solving for.
You DO know the circumference, so you can replace this variable with its number value as shown:
63=πd
The simplified version of this equation is:
d=63/π
the decimal form is:
20.05352282
