Answer:
Your answer is p= -2/3a + 13. I had this question
567 would round out to 600. If you are also rounding the three, then that is one. The answer to that would be 600. If you aren't rounding the three, the answer would be 1800.
Answer:
x=12 and y=4.3
Step-by-step explanation:
Given the sides of quadrilateral that are O N = 8 x − 8 , L M = 7 x + 4 , N M = x − 5 , and O L = 3 y − 6. we have to find the value of x and y so that LMNO be a parallelogram.
we know opposite sides of parallelogram are equal.
Hence, we have to find the value of x and y such that opposite sides becomes equal which implies LMNO is a parallelogram.
Equating opposite sides equal, we get
8x-8=7x+4 ⇒ 8x-7x=8+4=12 ⇒ x=12
implies, NM=x-5=12-5=7
NM=OL ⇒ 3y-6=7 ⇒ 3y=13 ⇒ y=4.3
Hence, x=12 and y=4.3
It is convenient to start by understanding what the curve looks like in the region of interest. A graph can help. The limits of the sum will be from x=0 to x=3. We want each area in the sum to have the same width, so that width will be 3/3 = 1. That is, the area of each of the summands will be its height multiplied by 1, its width. In short, we can obtain the required sum by simply adding the height of the function at the appropriate points. Note that this process is eased immensely by having a table of values of the function.
a) The left end of each interval is where x ∈ {0, 1, 2}. The area is then
f(0) +f(1) +f(2) = 3 + 4 + 3 =
10b) The right end of each interval is where x ∈ {1, 2, 3}. The area is then
f(1) +f(2) +f(3) = 4 + 3 + 0 =
7c) The middle of each interval is where x ∈ {0.5, 1.5, 2.5}. The area is then
f(0.5) +f(1.5) +f(2.5) = 3.75 + 3.75 + 1.75 =
9.25d) The trapezoidal rule averages the left and right ends of each interval. We can obtain the same result by averaging the Left Sum and the Right Sum.
(10 + 7)/2 =
8.5_____
For comparison, the actual area under the curve in the first quadrant is 9.00.
