Answer:

Step-by-step explanation:

Consider figure B. It has a uniform horizontal cross section of 2 m, and a height of 7 m. Its area is ...

A = bh

A = (2 m)(7 m) = 14 m²

Figure A decomposes into a rectangle that is 3 m × 5 m and an additional triangle that has a base of 3 m and a height of (7 -5) = 2 m.

The rectangle part of Figure A has an area of ...

A = bh

A = (3 m)(5 m) = 15 m²

Already this area is larger than the area of figure B, and we have not even added in the are of the triangle.

Figure A has the larger area.

_____

<em>Additional comment</em>

The area of the triangle of figure A is ...

A = 1/2bh = 1/2(3 m)(2 m) = 3 m²

so the total area of Figure A is (15 m² +3 m²) = 18 m².

Find the TWO integers whos product is -12 and whose sum is 1<br>

ahrayia [7]

Answer:

$\rm Numbers = 4 \ and \ -3.$

Step-by-step explanation:

Given :-

The sum of two numbers is 1 .

The product of the nos . is 12 .

And we need to find out the numbers. So let us take ,

First number be x

Second number be 1-x .

According to first condition :-

$\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}$

Hence the numbers are 4 and -3

The population of a city is modeled by the equation P(t)=232012e0.23t where t is measure in years. If the city continues to grow

Gennadij [26K]

In around 6.35 years, the population will be 1 million.

<h3> how many years will it take for the population to reach one million?</h3>

The population is modeled by the exponential equation:

$P(t) = 232,012*e^{0.23*t}$
