Answer:
2, 8, 90, 160
that is the focal, vertex l, direction
(2-c,y) is the answer for the problem.
Answer:
-3/4
Step-by-step explanation:
To find the slope, plug the coordinates into the slope formula.
y2 - y1 / x2 - x1
4 - (-2) / -7 - 1
6 / - 8
-3/4
George shouldn't think too far.
He should use the formula for Compound Interest.
Amount in compound interest, A = P(1+ r/100)ⁿ.
Where A = Amount, P = Principal, r is the rate per year, n = number of years.
Note: the expression (1+ r/100) is raised to power n.
From George's problem: P = 750, r = 22, I guess number of years , n = x
A(x) = 750( 1 + 22/100)ˣ
A(x) = 750( 1 + 0.22)ˣ
From your options I can't see an answer. Except the expression of option (A) is actually raised to power x, and not times x as stated in the option.
For us to find out how many times more expensive is the deli roast compared to the uncooked roast we need to change the units;
cost of 100g=0.221lb is $2.99
cost of 1 lb will therefore be:
1/0.221*2.99
=$13.53/lb
therefore the number of times more expensive the deli roast is compared to uncooked roast is:
[price of 1lb roasted meat]/[price of 1 lb uncooked meat]
=13.53/4.99
=2.7 times
