Step-by-step explanation:
One pound = $0.65
Total cost = c
Number of pounds to ship = p
Part a:
c = 0.65p
When p = 2
c= 0.65(2)
c = $1.30
Part b:
One pound = $0.65 - $0.05 = $0.60
c= 0.6p
Answer: (a) $1.30 (b) c= 0.6p
Answer:
4y+q(3-5q^2)
Step-by-step explanation:
common taking from 3q-5q^3
Answer:
1. gcd(77,30)=1
Since 1 is the last non zero remainder appearing in these equations then, 1 is the gcd of 77 and 30.
2. u=-11, v=18
Using the Euclidean Algorithm we have that
Now, we express the remainder as linear combinations of 49 and 30.
Then 
3. x=18
If 
then
for some 
.
Then, if k=7,
C.6 i think, sorry if it’s wrong but my reasoning was that 50 + 58 = 108 and the interior of a triangle is 180 degrees so then you would subtract 180 - 108 = 72, then i did some guess work plugging in the different answers into the equation and 11 x 6 + 6 = 72 which was the missing angle from before
Answer:
d)
Step-by-step explanation:
the polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by a linear polynomial x-r is equal to f(r). In particular, x-r is a divisor (that means a factor) of f(x), if and only if f(r)=0.
our r here is -1 to get x + 1.
f(-1) = 2×(-1)³ + 5×(-1)² - -1 - 6 = -2 + 5 + 1 - 6 = -2
the remainder is -2.
and since the remainder is <> 0, the binomial cannot be a factor.
