Step-by-step explanation:
f(x) = | x² - x + 3 |
f(-1) = |(-1)² - (-1) + 3| = |1 + 1 + 3| = |5| = 5
f(5) = |(5)² - (5) + 3| = |25 - 5 + 3| = |23| = 23
f(-10) = |(-10)² - (10) + 3| = |100 - 10 + 3| = |93| = 93
Answer:
y= 15/7x+4
Step-by-step explanation:
221.57
Explanation:
To round to the nearest tenth you would would look at the hundredths place. If it is higher than 5 you round the number in the tenth place up if it is lower than 5 you keep it the number in the tenth place the same. In this case you have 2 which is lower than 5 so you keep the 7 the same and bring everything else down.
The correct answer to this question is <span>d.) integral from 1 to 2 of (2/(x+1))
</span>To solve this:
Since Δx = 1/n.
lim (n→∞) Δx [1/(1+Δx) + 1/(1+2Δx)+ ... + 1/(1+nΔx)]
= lim (n→∞) Σ(k = 1 to n) [1/(1 + kΔx)] Δx.
x <---> a + kΔx
a = 0, then b = 1, so that Δx = (b - a)/n = 1/n
Since (1 + kΔx) combination, a = 1 so that b = 2.
Then, f(1 + kΔx) <-----> f(x) ==> f(x) = 1/x.
This sum represents the integral
∫(x = 1 to 2) (1/x) dx, so the correct answer is <span>d.) integral from 1 to 2 of (2/(x+1))

Answer: inequality
Step-by-step explanation:
An <u>inequality</u> is a sentence that uses the symbols >, <, ≥, ≤, or ≠ to show a relationship. Here are some different inequalities for an example:
6 < 11
7 > 2
12.5 ≠ 13.5
