Answer:
fragrance A $26
fragrance B $24
Fragrance A has the greater unit rate
Step-by-step explanation:
To find the price of fragrance A , take the price and divide by the number of bottle
$78/3 bottles = $26 per bottle
To find the price of fragrance A , we can look at the graph and find the price for 1 bottle on the x axis and go up until we hit the red line. The value of y is 24 dollars

centimeter is the best to meause with
Answer:
They are 15 prime numbers between 1 and 50
De Moivre's theorem uses this general formula z = r(cos α + i<span> sin α) that is where we can have the form a + bi. If the given is raised to a certain number, then the r is raised to the same number while the angles are being multiplied by that number.
For 1) </span>[3cos(27))+isin(27)]^5 we first apply the concept I mentioned above where it becomes
[3^5cos(27*5))+isin(27*5)] and then after simplifying we get, [243 (cos (135) + isin (135))]
it is then further simplified to 243 (-1/ √2) + 243i (1/√2) = -243/√2 + 243/<span>√2 i
and that is the answer.
For 2) </span>[2(cos(40))+isin(40)]^6, we apply the same steps in 1)
[2^6(cos(40*6))+isin(40*6)],
[64(cos(240))+isin(240)] = 64 (-1/2) + 64i (-√3 /2)
And the answer is -32 -32 √3 i
Summary:
1) -243/√2 + 243/√2 i
2)-32 -32 √3 i
Answer:
Midpoint: (-1, 11/2)
Step-by-step explanation:
Use the formula: (X1+X2)/2, (Y1+Y2)/2
(2-4)/2 , (4+7)/2
-2/2 , 11/2
(-1, 11/2)
