Answer: 41.16 cm cubed.

= (0.5 • 4.2 • 2.8) • 7 = 41. 16

Explanation: B = 1/2 base times hight of the triangle. Not the figure.
Remember the figure is also tipped over, and its not up right. So you’ll have to try to imagine and image it standing up right.

Total = 500 * ([(1 + .07)^26 -1] / .07) -500
Total = 500 * (4.8073529249 / .07) -500
Total = 500 * (68.6764703562) -500

a city has a population of 340,000 people suppose each year the population grows by 7% what will rhe population be after 12 year

NemiM [27]

So this is going to be an exponential equation, which the format is $y=ab^x$ , in which a is the initial value and b is the growth/decay rate.

In this case, a is going to be 340,000 and b is going to be 107%, or 1.07, since the population is going to be increasing by 7% and the equation is now $y=340000(1.07)^x$ .

Now replace x with 12 and solve.

$y=340000(1.07)^{12}$

Solve $1.07^{12}$ , and then if you don't round that answer and multiply it with 340000 you get $y=765745$ .

Answer:

(4x -3yi) (4x+3yi)

Step-by-step explanation:

We have a^2 + b^2

Over the complex number, this is equal to

(a-bi) (a+bi)

(4x -3yi) (4x+3yi)
