Answer:I believe the answer is c. not sure tell me if im wrong
Step-by-step explanation:
Answer:
The first two tables show y as a function of x.
Step-by-step explanation:
A relation is <em>not a function</em> if the same x-value shows up more than once in the table. That will be the case for the last two tables, each of which has x=2 show up twice.
Answer:
∴ ∑₁⁸i = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8
Step-by-step explanation:
Given:
To Find:
∑₁⁸i =?
Solution:
Σ This symbol called Sigma means "summation up"
∴ ∑ n mean sum for all n
But if ∑₁³n means Sum for n=1 , 2 ,and 3 ADD
∴ ∑₁³n = 1 + 2 + 3
∴ ∑₁⁸i = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8
Answer:
1
Rewrite 200200 as its prime factors.
\sqrt[3]{2\times 2\times 2\times 5\times 5}32×2×2×5×5
2
Group the same prime factors into groups of three.
\sqrt[3]{(2\times 2\times 2)\times 5\times 5}3(2×2×2)×5×5
3
Rewrite each group of three in exponent form.
\sqrt[3]{{2}^{3}\times 5\times 5}323×5×5
4
Use this rule: \sqrt[3]{{x}^{3}}=x3x3=x.
2\sqrt[3]{5\times 5}235×5
5
Simplify.
2\sqrt[3]{25}2325
6
Rewrite 2525 as {5}^{2}52.
2\sqrt[3]{{5}^{2}}2352
7
Use this rule: {({x}^{a})}^{b}={x}^{ab}(xa)b=xab.
2\times {5}^{\frac{2}{3}}2×532
Answer:
Slope = 2.3 or 2
Step-by-step explanation:
First, to find the slope of the given coordinates (9,22) and (15,36), we must establish what will be our starting and endpoint.
Let's have (9,22) be our starting point.
And (15,36) be our endpoint.
First, what is the change in x?
The change in x is 6, because 9 + 6 = 15. (Δx = 6)
Second, what is the change in y?
The change in y is 14, because 22 + 14 = 36. (Δy = 14)
Now we can find the slope by dividing the change in y over the change in x or Δy/Δx:
= 2.3 or 2
