Answer: no

Step-by-step explanation:

because when you Multiply 7 to the power of 2 its automatically greater than the actual answer and obviously the 9 to the power of 2 already is a lot greater than 11 times 11.

Answer:

It is not a right triangle because the other side is 11 and not 11.40  when we apply the Pythagoras theorem rule on it

Step-by-step explanation:

To determine whether it is a right triangle, all we simply need to do is to check using the Pythagoras theorem formula, Using the Pythagoras theorm formula;

opposite² + adjacent² = hypotenuse²

let opposite  = 7 and let adjacent = 9   let the hypotenuse be x, if we calculate and x gives 11 then we will know it is a right-triangle

7² + 9² = x²

49 + 81 = x²

130 = x²

Take the square root of both-side

√130 =√ x²

11.40 = x

Therefore it is not a right triangle because the other side is 11 and not 11.40  when we apply the Pythagoras theorem rule on it

Explanation:

[ Step One ] Factor \bold{x^2+4x-5}

\bold{x\left(x-1\right)+5\left(x-1\right)}

[ Step Two ] Rewrite Equation

\bold{\frac{\left(x-1\right)\left(x+5\right)}{5x^2-8x+3}}

[ Step Three ] Factor \bold{5x^2-8x+3}

\bold{\left(x-1\right)\left(x+5\right)}

[ Step Four ] Rewrite Equation

\bold{\frac{\left(x-1\right)\left(x+5\right)}{\left(5x-3\right)\left(x-1\right)}}

[ Step Five ] Cancel Out Common Factor \bold{x-1}

In 2018, the population of a district was 25,000. With a continuous annual growth rate of approximately 4%, what will the
const2013 [10]

Answer:

<h2>40,000 populations</h2>

Step-by-step explanation:

Initial population in 2018 = 25,000

Annual growth rate (in %) = 4%

Yearly Increment in population = 4% of 25000

= 4/100 * 25000

= 250*4

= 1000

This means that the population increases by 1000 on yearly basis.

To determine what the  population will be in 2033, we need to first know the amount of years we have between 2018 and 2033.

Amount of years we have between 2018 and 2033 = 2033-2018

= 15 years

<em>After 15 years, the population will have increased by 15*1000 i.e 15,000 more than the initial population.</em>

<em />

<em>Hence the population in 2033 will be Initial population + Increment after 15years = 25,000+15000 = 40,000 population.</em>
