Answer:

A

Step-by-step explanation:

Note that i² = - 1

Given

(7 - 5i)(2 + 3i) ← expand factors using FOIL

= 14 + 21i - 10i - 15i² ← collect like terms

= 14 + 11i + 15

= 29 + 11i → A

How do you divide 54,164 by 44 and show your work
sergejj [24]
To divide 54,164 by 44, we start from the first digit.

First we take the first 2 digits: i.e. 54 divided by 44, which gives 1 remainder 10.

Next, we join the next digit to the remainder and divide again by 44: i.e. 101 divided by 44, which gives 2 remainder 13.

Next, we join the next digit to the remainder and divide again by 44: i.e. 136 divided by 44, which gives 3 remainder 4.

Next, we join the next digit to the remainder and divide again by 44: i.e. 44 divided by 44, which gives 1.

We now joining all the results from our algorithm, to get that 54,164 divided by 44 is 1,231.

WILL GIVE BRAINLIEST IF RIGHT<br> how do you find the growth factor of a graph
notsponge [240]

Answer:

The growth "rate" (r) is determined as b = 1 + r.

Step-by-step explanation:

A growth factor is the factor by which a quantity multiplies itself over time. When trying to find the growth rate, you have to remember that the original exponential formula was y = ab^x. You will notice that in these new growth and decay functions, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r). The growth "rate" (r) is determined as b = 1 + r.

Please mark me the brainliest!?!
