A lab technician is using this exponential model, ​A(t)= 100e​ -0.8t ​to measure cells in a petri dish over a period of hours. (2 pts each) a. After several hours, would there be ​more​ cells or ​fewer​ cells in the petri dish?​ ​(circle one)

b. How many cells would there be after 10 hours? ​(round to the nearest hundreths)​

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
