Mathematics
1 answer:
solmaris [256]3 years ago
5 0

Answer:

Its the last option

y = 1488.33x + 23800 ; $172,600.

Step-by-step explanation:

The slope of the trend line = (median value for 2000 - median value for 1940) / 60

= 89300 / 60

= 1488.33.

So the equation is 1488.33x + 23,800

Estimate for 2040

is 1483.33* 100 + 23800

= 172,600.

Select all the expressions equivalent to: (4^5)⋅4^3 Group of answer choice 2^14 4^12 2^16 16^8 4^8 16^4
kumpel [21]

Answer:

Choices given as 2^{16}, 4^8 and 16^4 are correct.

Step-by-step explanation:

Given expression is,

(4^5)(4^3)

By applying law of exponents in the given expression,

(4^5)(4^3)=4^{5+3}

            =4^8

(4^5)(4^3)=(2^2)^5(2^2)^3

            =(2^{2\times 5})(2^{2\times 3})

            =2^{10}\times 2^6  

            =2^{16}

            =(2^4)^4

            =(16)^4

Therefore, choices given as 2^{16}, 4^8 and 16^4 are correct.

Ron gets $5 on the first day at work, the square of that amount on the second day, and three times the amount of the second day
Ket [755]

Answer:

5 + 25 + 75 = 105 dollars

Step-by-step explanation:

The easiest way is to just take this day by day.

day 1: 5 dollars

day 2: day1^2 = 5^2 = 25

day 3: 3 * day2 = 3 * 25 = 75

Then sum them: 5 + 25 + 75
