The Equation for parabola is y=-1/486 x² +6 and the height of the arc 5 feet is: 5 461/486 feet.

<h3>Equation for parabola</h3>

Using this equation to find the equation for parabola

y=a(x-54) (x+54)

y(0)=a(-54) (54)=6

-2916a=6

Divide both side by y6a

a=-2916/6

a=-486

Equation for parabola

y=-1/486 x² +6

Height of the arc 5 feet

When x=5

y=-25/486+6

y=2891/486

=5 461/486 feet

Therefore the Equation for parabola is y=-1/486 x² +6 and the height of the arc 5 feet is: 5 461/486 feet.

The trait of “freckles” is dominant and represented by A. No freckles is recessive and represented by a. A researcher crossed tw

Ivahew [28]

Answer:

It's wrong.

Explanation:

In the Punnett square, we will use F to represent the dominant freckles gene and f to represent the recessive lack-of-freckles gene. The first individual would have FF, because homozygous means that both alleles are the same. The second individual would have Ff, because heterozygous means that it has 2 different alleles. If the first individual passes down one of its "F" alleles and the second individual passes down its "F" allele, the offspring would have 2 dominant alleles, and the researcher's conclusion is disproven.

Determine whether or not the vector field is conservative. If it is conservative, find a function f such that f = ∇f. (if the ve

Arisa [49]

If F(x, y, z) = i + sin(z) j + y cos(z) k is conservative, then there exists a scalar function f(x, y, z) such that grad(f) = F, which means

∂f/∂x = 1

∂f/∂y = sin(z)

∂f/∂z = y cos(z)

Integrating each each of these equations gives

∫ ∂f/∂x dx = ∫ dx ⇒ f(x, y, z) = x + α(y, z)

∫ ∂f/∂y dy = ∫ sin(z) dy ⇒ f(x, y, z) = y sin(z) + β(x, z)

∫ ∂f/∂z dx = ∫ y cos(z) dz ⇒ f(x, y, z) = y sin(z) + γ(x, y)

It follows that α(y, z) = y sin(z) and β(x, z) + γ(x, y) = x + C where C is a constant. So

f(x, y, z) = x + y sin(z) + C

and F is indeed conservative.

What are the main rules of writing a will? check all that apply.

kykrilka [37]

Answer:

A) In most states, you must be eighteen or older.

B) The document must clearly state that it is your will.

E) A will must be written in sound judgement and mental capacity.

F) An executor must be named to oversee the distribution of the estate

Explanation:

The testament (from the Latin testario mentis, which means "testimony of the will") is the legal act by which a person disposes for after the death of the owner (which may be a family member or a person to whom he has esteemed) ) of all or part of their assets. It is not synonymous with making a dedication. Some authors maintain that it does not come from "testario mentis", but that its origins are found in the word "testis", for which reference is made to the witness; that is to say, the testament has no meaning as a material expression of will, but is an act in which this will is attested. The testament also admits non-patrimonial acts, such as the recognition of children.
