For this case we must find an expression equivalent to:

$8.4 * 10 ^ 2 =\\8.4 * 100 =$

We must run the decimal two spaces to the right, then:

$8.4 * 100 =\\840$

If we run a space on the right we have 84, so when running two spaces on the right we have: 840

Thus, 8400 is an expression equivalent to $8.4 * 10 ^ 2$

Answer:

840

serious [3.7K]

Answer:

A. $p=\dfrac{V}{1+rt}$

B. $2,307.69

Step-by-step explanation:

You are given the formula

$V=p+prt,$

where V = investment earning simple interest

p = principal,

r = interest rate

t = time

So,

A. $V=p(1+rt)\\ \\p=\dfrac{V}{1+rt}$

B. r = 0.06 (or 6% as percent)

V = $3,000

t =5

so,

$3,000=p+p\cdot 0.06\cdot 5\\ \\3,000=p+0.3p\\ \\1.3p=3,000\\ \\p=\dfrac{3,000}{1.3}\approx 2,307.69$

The slope of the line whose equation is 3x - 2y = 4 is 2/3 3/2 -2

7nadin3 [17]

Answer:

3/2

Step-by-step explanation:

The equation 3x-2y=4 can be written in the form of y=mx+c where m is the slope and c is the y intercept.

Therefore

2y=3x-4 and dividing both sides by 2 to have y at the LHS

y=3/2x-2

Therefore, 3/2 represents the gradient/slope
