  1. first you have to figure out how many times you can multiply ($185) without going over.
  2. Second you have to figure out what half of 185 is. (92.5)
  3. Finally you add the half (92.5) with the total from #1. (370)

Varvara68 [4.7K]
For the house A we have:
 f (x) = 124270 (1.04) ^ x
 Evaluating for 7, 8, 9 and 10 we have:
 f (7) = 124270 (1.04) ^ 7 = 163530.8422
 f (8) = 124270 (1.04) ^ 8 = 170072.0759
 f (9) = 124270 (1.04) ^ 9 = 176874.9589
 f (10) = 124270 (1.04) ^ 10 = 183949.9573

 For house B we have:
 
f (x) = 114270 (1.05) ^ x
 Evaluating for 7, 8, 9 and 10 we have:
 f (7) = 114270 (1.05) ^ 7 = 160789.3653
 f (8) = 114270 (1.05) ^ 8 = 168828.8336
 f (9) = 114270 (1.05) ^ 9 = 177270.2752
 f (10) = 114270 (1.05) ^ 10 = 186133.789

 We observe that for years 7 and 8 the value of house A is greater than the value of house B.

3x5 – 7x4 + 6x2 – 14x
Andreas93 [3]

Question is Incomplete; Complete question is given below;

What is the completely factored form of 3x5 – 7x4 + 6x2 – 14x.

Answer:

The Complete factorized form of given equation is x((x^3+2)(3x-7)).

Step-by-step explanation:

Given:

3x^5-7x^4+6x^2-14x

We need to factorize the above equation:

Solution:

On Solving the above equation we get;

Step 1:

First we will take a common factor which is 'x' so the equation will become as;

x(3x^4-7x^3+6x-14)

Step 2:

Now we will Rewrite the above equation so as to factorize the same we get;

x(3x^4+6x-7x^3-14)

Step 3:

Now we take 3x common factor from first 2 terms we get;

x(3x(x^3+2)-7x^3-14)

Step 4:

Now we will take 7 as common factor from last 2 terms we get;

x(3x(x^3+2)-7(x^3+2))

Step 5:

Now we can see the common factor between the 2 terms is x^3+2;

x((3x-7)(x^3+2))

Hence The Complete factorized form of given equation is x((x^3+2)(3x-7)).

joja [24]

Answer:

27.52 percent

Step-by-step explanation:

Percentage increase = (new - original)/ original * 100

new = 318270

old = 249583

Substitute in what we know

percentage increase = (318270-249583)/249583 *100

                                     = (68687/249583) *100

                                       .275207045*100

                                       27.5207045 percent
