<h2>
Sally's grocery bill 
</h2>
Step-by-step explanation:
Given that
Sally has a discount card that reduce the price of grocery bill in certain grocery store by 5%. It c represent the cost of Sally's groceries.
She got discount =
<h3>Therefore Sally's grocery bill =
</h3>
A) angles 4 and 5
b) angles 3 and 7
c) angles 1 and 8
Do you mean 5+7?
If so, that equals 12!
Ok, so from previous question
(x-h)^2=4p(y-k)
distance from focus to directix is 2
2/2=1=p
1>-1
focus is above the vertex
1 unit down from (0,1) is (0,0)
vertex at (0,0)
since focus is above, p is positive
(x-0)^2=4(1)(y-0)
x^2=4y
4y=x^2
divide both sides by 4
y=(1/4)x^2
f(x)=1/4x^2
2nd one is answer
Answer:
2.85 in²
Step-by-step explanation:
Area of triangle = 1/2 x base x height
1/2 x 1.9 x 3 = 2.85 in²
