Determine if y = 2x + 1 is a function

Answer:

Step-by-step explanation:

Answer:To simplify the expression "a raised to the negative third power over quantity 2 times b raised to the fourth power end quantity all cubed", we can follow these steps:

Step 1: Simplify the numerator.

a raised to the negative third power is equivalent to 1 over a cubed.

Step 2: Simplify the denominator.

2 times b raised to the fourth power is equivalent to 2b to the fourth power.

Step 3: Combine the simplified numerator and denominator.

So, the expression becomes 1 over a cubed divided by 2b to the fourth power, all cubed.

Step 4: Simplify the division.

When we divide by a fraction, we can multiply by its reciprocal.

The reciprocal of 2b to the fourth power is 1 over 2b to the fourth power.

Therefore, the expression simplifies to 1 over a cubed times 1 over the reciprocal of 2b to the fourth power, which is 1 over 2b to the fourth power.

In summary, the simplified expression is 1 over 2b to the fourth power times a cubed.

Answer:

20 million

Step-by-step explanation:

Given : The human population doubles approximately every 50 years

To Find:  If there were 2.5 million people in 1950 how many people are forecasted to populate the earth in 2100

Solution:

Equation for growth =

where a is the initial amount

y is the amount after x years

x denotes the time

A.T.Q

So, 20 million people are forecasted to populate the earth in 2100 .

Answer:

Answer:

Step-by-step explanation:

I have enclosed a picture of the quadratic formula because I cannot seem to write the proper formula since it wont let me

↪  Alright so first we need to work out values for A B AND C

↪  We need to rearrange this since its the wrong way around

↪  A = -3

B= -10

C= 5

↪  we substitute these values and we get x=0.44 and x=-3.78
