Answer:

3x^3+3x^2-30x -48

Step-by-step explanation:

we apply distributive property

3(x + 2)(x^2 − x − 8)

so we have:

(3*x+3*2)(x^2 − x − 8)

(3x+6)(x^2 − x − 8)

3x*x^2 - 3x*x -3x*8 + 6*x^2 -6*x -6*8

3x^3-3x^2-24x +6x^2 -6x -48

3x^3+3x^2-30x -48

The price of products may increase due to inflation and decrease due to depreciation. Derek is studying the change in the price
Amiraneli [1.4K]
Product A is increasing because the base 1.03 in the exponential is greater than 1.

The percent increase is (1.03-1)*100\%=0.03*100\%=3\% per year.

For product B, the rate of increase is \frac{10,201}{10,100}=1.01

The percent increase is (1.01-1)*100\%=0.01*100\%=1\% per year.

Product A has a higher percent increase.

A.75 cms<br> B.64 cms<br> C.90 cms<br> D.125 cms
nirvana33 [79]

Answer:

Ans.    64 cm

Step-by-step explanation:

we have to use the ratio of actual distance and distance on projection here.

Given,

Ratio of distance in projection and actual distance is  1:200,000

That means, 1 cm in projection will be 200,000 cm in actual distance.

Here,

Actual distance is 128 km.

we know, 1 km=100,000 cm

Now,  128 km=128,00,000 cm

So, actual distance is 128 00 000 cm.

Since, 200000 cm in actual distance means 1 cm in projection.

So,

for 12800000 cm in actual distance means 12800000/200000 cm in projection.

So, in the screen distance will be-

12800000 / 200000

=64 cm
