Answer:
Answer:
The total is: $ 1345.5
Step-by-step explanation:
It is given that:
I would like to purchase 20 products at a cost 65.00 per product.
This means that the cost of 20 products will be:
Also, there is a sales tax of 3.5%
This means that a person has to pay a extra 3.5% on the total cost of the items he purchased.
i.e. he need to pay 3/5% on $ 1300
This means that the amount of tax he need to pay is: 3.5% of 1300
= 3.5%×1300
= 0.035×1300
= $ 45.5.
Hence, the total cost is: $ 1300+$ 45.5
This means that the total cost is: $ 134.5
Answer:
<u>f(x) = x² - 4x + 2 or f(x) = (x - 2)²</u>
Step-b<u>y</u>-step explanation:
- The parabola touches the x-axis at only one point
- If we use y = a(x − h)² + k, we can see from the graph that h = 2 and k = 0
- This gives us y = a(x − 2)²
What is the value of "a"?
- We also see that the y-intercept is (0, 4)
- We can plug it into the equation
- 4 = a(0 - 2)²
- 4a = 4
- a = 1
<u>So, our quadratic equation will be</u> :
- y = 1(x - 2)²
- <u>y = x² - 4x + 2 or y = (x - 2)²</u>
This is an area problem where the area of a circle is pi*r^2.
A quiche with a diameter of 12 has an area of pi*6^2 = 36pi
So if it can feed 6 people, then the serving size per person is 6pi per person.
A quiche with a diameter of 10 inches has an area of pi*5^2 = 25pi
If each person requires 6pi worth of quiche, then 25pi/6pi = 4 1/6 people.
So yes, it can serve 4 people.
