Answer:

7^2

3^3

Step-by-step explanation:

Exponents signify how many times the base is multiples by itself. In the case of 7x7, 7 is the base and it is being multiplied by twice itself, resulting in an answer of 7^2

real estate math Speculator paid $25,000 net each for two 150 front-foot lots. Speculator split them into 3 lots with equal fron

Svetlanka [38]

Answer:

80%

Step-by-step explanation:

The original cost per front-foot was ...

$25000/150 = $500/3

The percentage profit relative to the initial investment is ...

profit percent = ((new value)/(old value) -1) × 100%

profit percent = (300/(500/3) -1)×100% = (9/5 -1)×100% = 80%

Speculator made 80% profit on the investment.

The base and height of the triangular mainsail of a sailboat ate 1.5 times greater than the base and height of the boats triangu

maw [93]

Remember that area always involves a length times a length.

The base of the mainsail is 1.5 times greater.
AND
The height of the mainsail is 1.5 times greater.

So the area of the mainsail is 1.5 times 1.5 greater.

1.5 • 1.5 = 2.25

The mainsail's area is 2.25 times greater than the smaller sail.

A farmer has a collapsable grain bag which can expand both vertically and horizontally as he needs it to. He wants to find a fun

bija089 [108]

Answer:

$3x^{3}+15x^{2}+x+5$

Step-by-step explanation:

We are told that the area of the bag can be represented by the function $f(x)=3x^{2} +1$ and as the bag is raised up its height can be represented by the function $g(x)=x +5$ .

Since we know that we can find volume of cuboid by multiplying base area to its height. We are given area and height of bag as functions. Now we will find volume of the bag by multiplying these functions.

$\text{Volume of collapsible bag}=f(x)*g(x)$

$\text{Volume of collapsible bag}=(3x^{2}+1)*(x +5)$

After using distributive property we will get,

$\text{Volume of collapsible bag}=3x^{2}(x+5)+1(x+5)$

$\text{Volume of collapsible bag}=3x^{3}+15x^{2}+x+5$

Therefore, the collapsible bag can hold $3x^{3}+15x^{2}+x+5$ grain.

Find the indicated limit, if it exists. limit of f of x as x approaches negative 10 where f of x equals negative 4 minus x when

monitta

The answer is 6. Here's why:

This function is defined in pieces. To find the limit as x approaches -10 we need to evaluate the limit as x approaches -10 from the right and from the left. In order for the limit to exist at x=-10 the left-hand limit and right-hand limit must be equal. Furthermore, they should be equal to the value of the function at -10. Here f(-10)=6.

Let's find the limit as x approaches -10 from the left. Here the values of x would be less than -10. That is x<-10 so we use f(x)=-4-x making the limit -4--10=-4+10=6

Let's find the limit as x approaches -10 from the right. Here the values of x would be greater than -10. That is x>-10 so we use f(x)=x+16 making the limit -10+16=6

Since the lmit from the right and from the left are equal and they also equal the value of the function at x=-10, the limit is 6. $lim$
