Answer:

Step-by-step explanation:

Hello,

If you take

$\displaystyle f(x)=\dfrac{2}{x}\\\\g(x)=\dfrac{1}{x}\\\\\dfrac{f(x)}{g(x)}=2\\\\ lim_{x\rightarrow+\infty} \ \dfrac{f(x)}{g(x)} = 2\\\\lim_{x\rightarrow+\infty} \ f(x) = 0 \\\\lim_{x\rightarrow+\infty} \ g(x) = 0\\\\\text{So at the limit this is somehow } \dfrac{0}{0}=2$

This is why in Algebra we usually considered that $0^0=1$ but this is not true in calculus.

Thanks

A certain right triangle with integer side lengths has perimeter $72$. What is its area?

JulijaS [17]

Answer: 216 square units

====================================================

Explanation:

A common pythagorean triple you may be familiar with is the 3-4-5 right triangle. This has two legs of 3 and 4, and a hypotenuse of 5. The perimeter is 3+4+5 = 7+5 = 12. Note how this is a factor of 72.

If we multiply the perimeter (12) by 6, then 12*6 = 72. So we have scaled the triangle by a factor of 6. Each length is 6 times longer

the side length 3 becomes 3*6 = 18

the side length 4 becomes 4*6 = 24

the side length 5 becomes 5*6 = 30

The new perimeter is 18+24+30 = 42+30 = 72

The last step is to find the area. The two legs of this triangle are the base and height

area = 0.5*base*height

area = 0.5*18*24

area = 9*24

area = 216

-----

Or you could find the area of the 3-4-5 right triangle to get

area = 0.5*base*height = 0.5*3*4 = 6

then multiply by 36 to get 6*36 = 216. The 36 is the square of the scale factor 6 we applied above. The new lengths are 6 times longer, so the new area is 6^2 = 36 times larger.

At the time of her grandson's birth, a grandmother deposits $ 3000 in an account that pays 3 % compounded monthly. What will be

GaryK [48]

Answer:

The value of the account will be $5,628

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=21\ years\\ P=\$3,000\\ r=3\%=3/100=0.03\\n=12$

substitute in the formula above

$A=3,000(1+\frac{0.03}{12})^{12*21}$

$A=3,000(1.0025)^{252}$

$A=\$5,628$

therefore

The value of the account will be $5,628

Translate the sentence into an inequality.

nataly862011 [7]

The sentence "Four times the sum of a number and 17 is at least −26" translated to an inequality is 4(x+17) ≥ -26

<h3>Translating sentences into inequality </h3>

From the question, we are to translate the given sentence into an equality.

The given sentence is

Four times the sum of a number and 17 is at least −26

Let the unknown number be x

Then,

The sum of a number and 17 will be

x + 17

Then,

Four times the sum of a number and 17 can be written as

4(x+17)

Now,

"At least -26" means it is greater than or equal to -26

Thus,

Four times the sum of a number and 17 is at least −26 becomes

4(x+17) ≥ -26

Hence, the sentence "Four times the sum of a number and 17 is at least −26" translated to an inequality is 4(x+17) ≥ -26.
