Which equation demonstrates the multiplicative identity property?
12345 [234]

Answer:

(-3+5)(1)=-3+5

Step-by-step explanation:

The multiplicative identity is 1.

The multiplicative identity property days that, if you multiply a real number by 1, that result is the same real number.

This is demonstrated in option B of the given alternatives, where we have:

( - 3 + 5)(1) =  - 3 + 5

The multiplication by did not change b the value.

Allen runs 8 miles in three hours at a steady pace how long does it take him to run 3 miles
mamaluj [8]
First find the speed...
8 miles per 3 hrs

8/3 = 2 2/3 m/hr

2 2/3 m/hr × x/3 m =
2 2/3 ÷ 3 = x
8/3 ÷ 3 = x
8/3 × 1/3 = x
8/9 = x

It takes 8/9 of an hour to run 3 miles. Multiply 8/9 × 60 to find out how many minutes.

8/9 × 60 = 53.33 minutes

Will mark brainliest

Using the given definition and \Delta x=\frac{0-(-2)}n=\frac2n, we have

\displaystyle \int_{-2}^0 (7x^2+7x) \,dx = \lim_{n\to\infty} \sum_{i=1}^n \left(7\left(-2+\frac{2i}n\right)^2 + 7\left(-2+\frac{2i}n\right)\right) \frac2n \\\\ ~~~~~~~~ = \lim_{n\to\infty} \frac2n \sum_{i=1}^n \left(14 - \frac{42i}n + \frac{28i^2}{n^2}\right)

Recall the well-known power sum formulas,

\displaystyle \sum_{i=1}^n 1 = \underbrace{1 + 1 + 1 + \cdots + 1}_{n\,\rm times} = n

\displaystyle \sum_{i=1}^n i = 1 + 2 + 3 + \cdots + n = \frac{n(n+1)}2

\displaystyle \sum_{i=1}^n i^2 = 1 + 4 + 9 + \cdots + n^2 = \frac{n(n+1)(2n+1)}6

Reducing our sum leads to

\displaystyle \int_{-2}^0 (7x^2+7x) \,dx = \lim_{n\to\infty} \frac2n \left(\frac{7n}3 - 7 + \frac{14}{3n}\right) = \lim_{n\to\infty} \left(\frac{14}3 - \frac{14}n + \frac{28}{3n^2}\right)

As n goes to ∞, the rational terms containing n will converge to 0, and the definite integral converges to

\displaystyle \int_{-2}^0 (7x^2+7x) \,dx = \boxed{\frac{14}3}
