Answer:

a) The negative sign indicates that progression is decreasing in time and decreases by 18 percent each month.

b) Antonio is expected to make a profit of 37445.17 in 7 months from now.

Step-by-step explanation:

a) The equation described on statement represents a geometrical progression, which is defined as:

y = C_{o}\cdot (1+ r)^{x} (1)

Where:

C_{o} - Initial amount, measured in monetary units.

r - Rate, dimensionless. (The progression is increasing when r > 0, and decreasing when -1 < r < 0)

x - Time, measured in months.

y - Profit, measured in monetary units.

Given that y = 150,210\cdot (0.82)^{x}, we calculated the rate below:

1+r = 0.82

r = 0.82-1

r = -0.18

The negative sign indicates that progression is decreasing in time and decreases by 18 percent each month.

b) If we know that x = 7, then the expected amount for Antonio in 7 months from now is:

y = 150,210\cdot (0.82)^{7}

y = 37445.17

Antonio is expected to make a profit of 37445.17 in 7 months from now.

A triangle has one leg that measures 14 feet and the hypotenuse is 50 feet. What is the length of the other leg?
Aliun [14]
Ok so we are using the Pythagorean theorem so were gonna do A^2 + B^2 = C^2

It don't say which leg we have so you can use either a or b.
Which would get us 14^2 + B^2 = 50^2
14*14 =196 , 50 *50 =2500
Then we have to  subtract the two.
So 2500 - 196 = 2,304
Then you take the take the square root of that answer and you have your other leg. 
The square root of 2,304 is 48
So the missing leg = 48

Alberto uses the steps below to solve the equation One-half x minus 3 equals 7. Step 1: One-half x minus 3 plus 3 equals 7 plus
natka813 [3]

Answer:

Identity property of multiplication

Step-by-step explanation:

From step 5:

1x = 20

Here, to solve for x so that the variable x stands alone, Alberto uses the identity property of multiplication, which justifies what he has in step 6.

Step 6:

x = 20

According to the identity property of multiplication, any value you multiply by 1 gives you that same value.

Therefore, 1x = 1 × x = x.

The variable x multiplied by 1 will give you x.

On Sunday Sheldon bought 3 and 1/2kg of plant food. He used 1 and 2/3kg on his strawberry plants and used 1/4kg for his tomato p
notsponge [240]

The remaining plant food is: 1 7/12 kg

Step-by-step explanation:

Given

Total Plant food = 3 1/2 kg

Plant food used on Strawberry Plants = 1 2/3 kg

Plant food used on tomato Plants = 1/4 kg

We will first calculate the total food plant used and then subtract the used plant food from the total plant food.

So,

Total\ Plant\ Food\ used=1\frac{2}{3}+\frac{1}{4}\\=\frac{5}{3}+\frac{1}{4}\\=\frac{20+3}{12}\\=\frac{23}{12}

Now,

Left\ Food\ Plant=3\frac{1}{2}-\frac{23}{12}\\=\frac{7}{2}-\frac{23}{12}\\=\frac{42-23}{12}\\=\frac{19}{12}\\=1\frac{7}{12}

The remaining plant food is: 1 7/12 kg
