Answer:
Step-by-step explanation:
Pattern 1 consists of
small squares (here n = 1 and ).
Pattern 2 consists of
small squares (here n = 2 and ).
Pattern 3 consists of
small squares (here n = 3 and ).
Thus, pattern n consists of
small squares.
For these questions to be true and the equation of the tangent to have an equal y to the equation of the parabola i guess there has to be a "c" and in that case integrate the equation of the tangent you will have a = 5 and b = -18 then you substitute in the equation of the parabola with the point you have you will find that "c" = 21 and so the equation of the parabola becomes y = 5x^2 - 18 x +21
Answer:
Solution:
Given, cost price = $784.50
Profit = 6.5% of cost price
= 6.5/100 × $784.50
= $50.9925 [since, profit% is always on C.P.]
And selling price = cost price + profit
= $784.50 + $50.9925
= $835.4925
Hence, selling price = $835.4925
Answer:
x=-2.2 y=-1.6
Step-by-step explanation:
8x+y=-16
-3x+y=5
5x=-11
x=-11/5 or -2.2
-3x+y=5
-3(-2.2)+y=5
6.6+y=5
-6.6+y=-6.6
y=-1.6
If you have a graphing calculator one way to know you are right is put the left side in Y1 and the right side in Y2 then hit 2nd trace and intersection then find the intersection and the X value is your answer. If you don't have a graphing calculator then I'm sorry
