given that the degree of the polynomial f(x) is 4, which of the following most accurately describes the number of x-intercepts that f(x) has?

Answer:

D. -1,1, -1/7,1/7

Step-by-step explanation:

Use all the factors of the leading coefficient, 7. And also, all the factors of the constant, 1.

Put the factors of the constant on top (numerator). Put the factors of the leading coefficient on the bottom (denominator).

+- 1/1 and +- 1/7

Simplifying:

-1, 1, -1/7, 1/7

That's it. Just list of possibilities of the rational zeroes.

By evaluating the exponential equation, we will see that the amount that Erica owes after 6 years is $8551.56

Here we just need to use the exponential equation:

A = P*(1 + r/n)^(n*t)

Where A represents the amount owed t years after, and the other letters represent:

Replacing all that in the given quadratic equation we will get:

A = $5,300*(1 + 0.08/12)^(12*6) = $8551.56

Perpendicular lines (or segments) really structure four right points, regardless of whether only one of the right points is set apart with a case.

Let m and n be lines that converge line a. Let m be perpendicular to a. This implies that every one 4 of the points framed by the convergence of m and an are 90°.

Allow n to be opposite to a. This implies that every one 4 of the points framed by the convergence of n and an are likewise 90°.

Since the points are all consistent, this implies that the equivalent side inside points (between lines m and n) are harmonious. In the event that two same-side inside points are harmonious, the lines are equal. In a direction plane, two particular nonvertical lines are equal if and provided that they have a similar slant.

When a 100-n box is suspended by a rope from an overhead support and a horizontal force of 58 n is applied to the box, the angle with the vertical is 30.11°.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint.

What is inequality?

An inequality in mathematics depicts the connection between two values in an algebraic statement that are not equal. One of the two variables on the two sides of the inequality may be greater than, greater than or equal to, less than, or less than or equal to another value, according to inequality signals.

5(x – 2)(x + 4) > 0

First we solve for x, we replace the inequality sign by = sign

5(x – 2)(x + 4) = 0

Divide both sides by 5

(x – 2)(x + 4) = 0

Now we set each factor =0  and solve for x

x-2 =0 , so x= 2

x+4 =0, so x= -4

Now we use number line and make three intervals

Step-by-step explanation:

Standard deviation is used to measure the depth of a dataset relative to its mean and is taken by the square root of its variance.

The correct option is c.

The mean of X is 7 and the variance is 35.

                           2                                 12

Let Y be a random variable.

X and Y are binomials.

E(X-Y) = E (X) - E(Y)

Write the formula for the variance of X and Y.

Var(X-Y) = Var (X) - Var (Y)

where x and y are independent covers (x,y) is 0.

now,

Var(X-Y) = 35 + 35

Because the standard deviation is the square root of the variance.

S.D = √((35/12) +(35/12))

The vertex angle of an isosceles triangle is not equal to the base angles of the isosceles triangle.

Given, an isosceles triangle

and we are asked that is vertex angle congruent to the base angles,

Let suppose ABC is an isosceles triangle with AB = AC

as we know that the angles opposite to the equal sides are also equal.

so, ∠ABC = ∠ACB

now, if ∠ABC = ∠ACB = x

then, on using angle sum property, we get

∠ABC + ∠ACB + ∠BAC = 180°

x + x + ∠BAC = 180°

∠BAC = 180° - 2x

as, x ≠ 180° - 2x

therefore, ∠BAC ≠ ∠ABC

So, the vertex angle of an isosceles triangle is not equal to the base angles of the isosceles triangle.

For the given cost function, the maximum profit is $250.

What is profit maximization?

According to the firm theory, a company is founded with the intention of maximizing profits.

A company must run at the lowest possible cost while maximizing revenues in order to accomplish this.

When marginal costs and marginal revenue are identical, profits are maximized.

1. Determine the profit maximizing output.

For a firm in a competitive market, the marginal revenue is equal to the price (MR = P)

Get the MC by differentiating the total cost with respect to the quantity (Q)

C = 50 + 3Q^2

dC / dQ =6Q

MC = 6Q

Profit will be maximized when: MR = MC

MR = MC

60 = 6Q

Q =10

This is the profit maximizing output.

2. To get the maximum profits substitute this value into the equation:

Profit = Total revenue - Total cost

Profit = (P*Q) - (50 + 3Q^2)

Profit = (60*10) - (50 + 3*10^2)

Profit = 600 - 350

Profit = 250

The equivalent resistance of the circuit is d)11.5 ohms. So, correct option is d.

We know very well that net resistance when resistors are connected in parallel and net resistance when resistors are connected in series is different.

So, we can see that three 4.7kΩ are connected in parallel.

So, using formula of net resistance in parallel

=>1/Rₙ=(1/R₁)+(1/R₂)+(1/R₃)

Therefore,1/Rₙ=1/4.7+(1/4.7)+(1/4.7)

=>1/Rₙ=3/4.7kΩ

=>Rₙ=4.7/3kΩ

=>Rₙ=1.5kΩ

Now, we have net resistance of three resistors.

Now, remaining three resistors are now connected in series

So, using formula of net resistance when resistors are connected in series=Rₙ=R₁+R₂+R₃

So, three resistors have resistance 4.7kΩ,1.5kΩ,5.2kΩ respectively

Therefore, Rₙ=4.7+1.5+5.2=11.5kΩ.

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare two values. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign in between. Sometimes it can be about a "not equal to" relationship, where one thing is more than the other or less than. In mathematics, an inequality is a relationship that results in a non-equal comparison between two numbers or other mathematical expressions.
