Step-by-step explanation:

the surface area where the slice was made is 1 cm on one side and 2 cm on the other side, multiply these for the area of the sliced section 1x2=2

The problem says that the distance D to the horizon is directly proportional to the square root of the elevation E of the observer, so:

The person who is 36 feet above the water ⇒ √36=6

A person 49 feet above the water ⇒ √49=7

So, by proportions, you have:

(7/6)x7.4= 8.63 miles

Therefore, the answer is: a person 49 feet above the water can see 8.63 miles

What does the fundamental theorem of algebra and its corollary tell you about the roots of the polynomial equation p(x)=0 where

denis23 [38]

Answer:

A polynomial with complex coefficients of degree n has n complex roots, counted with multiplicity.

Step-by-step explanation:

We are given a polynomial p(x) in the question with degree n.

The degree n means the n is the highest power of variable in the given polynomial.

The equation:

$p(x) = 0$

Fundamental theorem of Algebra

The Fundamental theorem of Algebra states that a a polynomial of degree n will have n roots of the equation.

This can further be explained as:

A polynomial with complex coefficients of degree n has n complex roots, counted with multiplicity.

Beckett purchase the diamond ring in 2012 for $12,000 if the value of the rain increases by 32% each year what will the ring be

Brums [2.3K]

Answer:

$119520

Step-by-step explanation:

Given: Purchase price of Diamond ring= $12000

Value of ring increase by 32% each year.

First finding number of year between 2012 and 2040, to know the time period of value appreciation.

Time period= $2040-2012= 28\ years$

∴ Time period of value appreciation is 28 years.

Now, finding the value of diamond ring increased after 28 years.

Value of ring increased after 28 years= $\frac{12000\times 32\times 28}{100}$

∴ Increased value of diamond ring after 28 years= $107520

Next, Value of diamond ring after 28 years= $12000+107520= \$ 119520$

Hence, value of diamond ring in 2040 is $119520
