Y' = -2x+a
0 = -2(3)+a
6=a
8=-(3)^2 +(3)(6)+b
b=-1
There are 4 quarts in a gallon.
In two gallons would be 8 quarts.
2 gallons - 5 quarts = 8 quarts - 5 quarts = 3 quarts.
Note: 3 quarts is 3/4 or .75 of a gallon.
Keep trying at this question, I believe in you! Here's the answer just in case. :)
Answer: 0.83644865915
Nearest hundredth would be 0.84.
I can explain it if you'd like.
Edit: Here's how I did it just in case anybody wants to know :) Not that anybody wants to know but just in case because you never know! :)
SOH CAH TOA
sine=opposite/hypotenuse
cosine=adjacent/hypotenuse
tangent=opposite/adjacent
So the cosine of W would be 65(the adjacent side)/97(the hypotenuse)
Because you don't know what W equals, you'd use a calculator and click the little 2nd button, then click the cos button. And then you'd type in the 65/97 and hit the equals button and that's the answer!
If I'm incorrect I guess tell me somehow? Alright, have a great day/night! ^-^
Answer: $6.96
Step-by-step explanation:
To find out what 8% of $87 is, you have to convert the 8% into decimal form which is 0.08. Then you have to multiply that by $87
87*0.08 = 6.96
Now, we know $6.96 is 8% of $87 which is how much she will be paying in tax
Answer:
Putting the value in x = 2 , y =4 in 2x - 2y we get,
2 × 2 - 4× 2= 4-8 = -4
Putting the value in z = 3 in z - 5 we get,
z - 5 = 3 - 5 = -2
