12+49i
when you get i^2 it's the same as multiplying by -1 so
factoring it out will turn out like this
15i^2+40i+9i+27
instead of 15 i^2 multiply 15 x-1
-15+49i+27
12+49i
The first thing we must do to solve the problem is to define the variables.
We have then:
n: pounds of grapes
c: total price
We have to:
"The price of grapes at a farm is $ 1.85 per pound"
Therefore, the equation will be:
c = 1.85n
Answer:
c = 1.85n
Answer:
a. y = -7cos(x) +7
Step-by-step explanation:
The middle level of the gum is 7 inches above the ground, and it oscillates 7 inches either side of that. Thus the offset of the cosine function (average height) is 7 and the multiplier (amplitude of oscillation) is also 7. The -7 on the cosine multiplier means the height of the gum is zero at x=0.
Answer:$55,000
Step-by-step explanation: If you’re are worried about the amount of computers don’t because that is unnecessary.they didn't sell any computers this month or it would have been mentioned in the problem. I decided to make the sum of phones they sold 100 because half of 100 is 50. So they sold 100 phones and 50 tablets. I did 50 x 300= 15,000 because 300 is the price of 1 tablet. Then I did 100 x 400=40,000 because 400 is the price of 1 phone. Then I added the sums together (15,000+40,000=55,000).
Answer:
12 cups of sugar
Step-by-step explanation:
The recipe uses 3 cups of sugar for every 8 cups of flour.
The diagram that models the ratio is the upper one with 3 pink squares of sugar and 8 green squares of flour.
If she uses 32 cups of flour, she is making 4 times the recipe since 32 = 4 × 8.
Then she also needs 4 times the amount of sugar.
4 × 3 = 12
Answer: 12 cups of sugar
