initial population of a town is 3400 and it grows with a doubling time of 10 years what will the population be in 8 years

1 answer:

6 0

So in 10 years, the population will double.

8 years is just before doubling to 6800.

If you consider 10 years to be 100% of the doubling time, 8 years is 80%.

And 80 as a decimal is 80/100 = 0.8

So the answer is 0.8 * 6800, simplify.

Answer:

Step-by-step explanation:

3x - 6y = -1

-6y = -1 -3x

-6y = -(1+3x)

y = -(1+3x)/-6

y = (1 + 3x )/6

Is xsquare+1/xsquare equal5 is quadratic or not

MAXImum [283]

Answer:

Yes, it is a quadratic equation.

Step-by-step explanation:

Let's solve it to make it a quadratic equation:

=> $\frac{x^2+1}{x^2} =5$

=> x²+1 = 5x²

=> 5x²-x²-1 = 0

=> 4x²-1 = 0

Comparing it with the standard form of quadratic equation i.e.

$ax^2+bx+c = 0$

So, we get

a = 4 , b = 0 and c = -1

So, yes. It is a quadratic equation and it is a pure quadratic equation since b is equal to 0.

Answer:

Measure of ∠B = 51°.

Step-by-step explanation:

The sum of the measures of any triangle will always add up to 180°. Also the sum of two supplementary angles, or angles that are side by side on a straight line, will also add up to 180°. In order to find the measure of ∠B, you need to first find the measure of ∠C. ∠C is supplementary to the angle of 113°, so we can find ∠C: 180 - 113 = 57°. Now that we know ∠A and ∠C, we can solve for ∠B: 180 = 72 + 57 + ∠B or 180 = 129 + ∠B, subtracting 129 from both sides, we get ∠B = 51°.
