The resulting shape is a cylinder, with axis along y-axis.
The horizontal cross section is a circle with radius √ (40) , which is the distance between (0,0) and (6,2).
Answer: .
Step-by-step explanation:
Total amount remaining = Initial amount in the card-( Cost per cup × (Number of cups) )
Each cup of coffee costs $1.50 and after buying 4 cups of coffee, the card had a $9 remaining balance.
i.e. 9 = Initial amount in card - (1.50 × 4)
⇒ 9 = Initial amount in card - (6)
⇒ Initial amount in card = 9+-6 =15
⇒ Initial amount in card = $15
Let A be the amount money remaining on the card after buying x cups of coffee.
So, A = 15 - 4x
Hence, the required equation is .
First of all you times 2.16.... by 100 to get 21.61616.....
you then minus the original number to get 21.4.
You can then times that by 10 to why 214 and you can divide 214 by 99:
214/99 = 2.161616
Hope this helps! :)
Answer:
I'm pretty sure it's -4
Step-by-step explanation:
If you substitute in -2, you get e(-2)= -(-2)+ -6
which is equal to 2-6
2-6=-4
Answer:
y = 3x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3, thus
y = 3x + c ← is the partial equation of the line
To find c substitute (1, 4) into the partial equation
4 = 3 + c ⇒ c = 4 - 3 = 1
y = 3x + 1 ← equation of line
