A) The function models exponential decay
B) The function models exponential growth
C) The rate of growth or decay is 2%
D) The rate of growth or decay is 20%
E) The rate of growth or decay is 8%
F) The rate of Growth or Decay is 80%
G) Two weeks after the initial ant became sick, there are only 10 ants remaining.

Answer:

A, D, H

Step-by-step explanation:

The function models exponential decay because the factor is 0.8 which is < 1

0.8 means 80% of the previous which is a decay of 100 - 80 = 20%

50(0.8^x)

50(0.8²)

= 32

mel-nik [20]

Answer:

#1

<u>Since half of the numbers are even, 2, 4, 6</u>

  • P(even) = 3/6 = 1/2

#2

<u>Multiple of 3 are 3 and 6:</u>

  • P(multiple of 3) = 2/6 = 1/3

#3

<u>The numbers ≤ 4 are: 1, 2, 3, 4</u>

  • P(≤4) = 4/6 = 2/3

#4

<u>Prime numbers are 2, 3, 5</u>

  • P(prime) = 3/6 = 1/2

#5

<u>Numbers > 1 are 2, 3, 4, 5, 6</u>

  • P(>1) = 5/6

#6

<u>A four, there is one option</u>

  • P(4) = 1/6

Please help! If the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms, what is the voltage?
Leona [35]

The value of the voltage is 18 - j volts if the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms option (c) is correct.

<h3>What is a complex number?</h3>

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have:

The current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms.

As we know,

V = IR

V = (3 + j2)(4 - j3)

\rm V=\left(3\cdot \:4-2\left(-3\right)\right)+\left(3\left(-3\right)+2\cdot \:4\right)j

j² = -1 (complex part)

After simplification:

V = 18 - j  volts

Thus, the value of the voltage is 18 - j volts if the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms option (c) is correct.

Greatest common factor for 8x and 40
CaHeK987 [17]
The GCF of 8x and 40 is 8

40 | 2
20 | 2
10 | 2
  5 | 5
  1 


8 | 2
4 | 2
2 | 2
1

40 = 2³ * 5
8 = 2³

We take only common factors with lowest exponent.

So 2³ = 8
