Choose the polynomial that is written in standard form 7x^5+8x^8+27x
Nataliya [291]

Answer: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3

Step-by-step explanation:

In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.

Then the correct option is d.

Where the degree of the first term is (4 + 1) = 5

The degree of the second term is (2 + 2) = 4

The degree of the third therm is 3.

We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:

-3*x^4*y + 2*x^2*y^2 + 5*y^3

The equation for free fall at the surface of some planet (s in meters, t in seconds) is s=2.86t^2. How long does it take a rock
kotykmax [81]

The time taken by the rock will be 8.77 seconds.

<h3>What is speed?</h3>

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

Given that:-

The equation for free fall at the surface of some planet (s in meters, t in seconds) is s = 2.86t²

The time will be calculated by using the speed formula.

Speed = Distance \ Time

25.1   = 2.86t² \ t

t   =  25.1 / 2.86

t   =  8.77 seconds

Therefore the time taken by the rock will be 8.77 seconds.

An architect is sketching a blueprint of a patio for a new fence. On the blueprint, C is the midpoint of segment AD. Point B is
Gre4nikov [31]

Answer:

<u><em>The length of AD is 32 feet</em></u>

Step-by-step explanation:

<u>Proportional distances </u>

When distances are proportions of others, we can express all of them as relative fractions until we reach some known distance and solve for the desired length

Let's call x the length of AD. Given C is the midpoint of AD, then

\displaystyle AC=CD=\frac{x}{2}

Given B is the midpoint of AC, then

\displaystyle AB=BC=\frac{AC}{2}=\frac{x}{4}

If we know BC=8 feet

\displaystyle \frac{x}{4}=8\ feet

\displaystyle x=32\ feet

The length of AD is 32 feet
