Noah's ambition was $90, and he raised $54 toward that total, or 60% of his fundraising target, in order to benefit the animal sanctuary.

A mathematical equation is a formula that connects two statements using the equal sign (=) to denote equivalence. An algebraic equation is a mathematical statement that establishes the equality of two mathematical expressions. For example, the variables 3x + 5 and 14 are separated by an equal sign in the equation 3x + 5 = 14. Mathematical equations are used to express the connection between two phrases on either side of a letter. There is frequently just one variable, which is also the symbol. example: 2x - 4 = 2.

given

60% x what= $54

Then, by converting 60% to a decimal, we can turn it into a useful number: 0.6. We will substitute x for what because we also need to make "what" simpler to use:

0.6x=54

Get x by itself next, which is referred to as isolating the variable. To accomplish this, divide both sides by 0.6, which is referred to as employing inverse operations.

You must obtain x=90.

The greater than and less than symbols are generally used to represent the inequality expressions. The symbol used to represent greater than is “>” and less than is “<”. If one value is larger than the other value we use greater than. Similarly,if we want to represent one value that is less than the other value we use less than.

Many teachers use the Alligator Method analogy to teach greater than and less than. They will draw an Alligator mouth on the greater than and less than signs.We can say the alligator is going to want to eat more.

The position of the sprinter is equal to the value of definite integral of the given velocity function v(t). The position at t = 4, 7, and 9 is 8, 8, 0.

The velocity is the first derivative of the position function. The position function is given in the attached picture.

s'(t) = v(t)

The position at time t is therefore equal to the definite integral from t = 0 to time t.

Since the graph is linear, the evaluation of each definite integral is equal to the area of triangles underneath the lines.

∫₀⁴ v(t) dt = (1/2) x 2 x 6 = 6

∫₄⁷  v(t) dt = (1/2) x 1 x 8 - (1/2) x 2 x 4  = 0.

∫₇⁹  v(t) dt = 2 x (-4) = -8

The position at t = 0 is s(0) = 2

Hence,

s(4) = s(0) + ∫₀⁴ v(t) dt  = 2 + 6 = 8

s(7) = s(0) +  ∫₀⁴ v(t) dt + ∫₄⁷  v(t) dt = 2 + 6 + 0 = 8

s(9) = s(0) +  ∫₀⁴ v(t) dt + ∫₄⁷  v(t) dt  + ∫₇⁹  v(t) dt = 2 + 6 + 0 - 8 = 0

The polynomial is x^4 - 8x^3 - 30x^2 + 144x + 405 = 0. The solution is obtained using the concept of bi-quadratic equation.

A 4-degree equation is a bi-quadratic equation.

Sometimes the phrase "bi-quadratic equation" is used as a substitute for the phrase "quartic equation." Such problems variable are straightforward to resolve because they can be reduced to quadratic equations in the variable x=z^2, which can then be solved for x using the quadratic formula and then in terms of the original variables by calculating the square roots.

Here,

We are given two roots of the bi-quadratic equation which are -3 and 7 - 2i.

Now, we will find the other two roots of the bi-quadratic equation by using the conjugates of the given roots.

In order to find the conjugate of complex numbers, we have to change the sign of the imaginary part.

So, we will get the conjugate of 7 - 2i = 7+2i

Thus, all the four roots of the bi-quadratic equation are -3, 7+2i, 7 - 2i and -3.

If two roots of an equation are given as a and b, then we can express the equation as (x-a) (x-b) = 0.

So, using this, we will form the equation with two imaginary roots 7+2i and 7−2i, which is given as:

[x-(7−2i)][x-(7+2i)]=0

⇒[x-7+2i][x-7-2i]=0

⇒[(x-7)+2i][(x-7)−2i]=0

Using the identity (a+b)(a-b)=a^2-b^2 , we get

(x-7)^2-(2i)^2=0

∵i=√-1

⇒(x-7)^2+(√-4)^2=0

⇒(x-7)^2+(-4)=0

⇒(x-7)^2 - 4=0

Now we will form the equation with roots -3 and -3, which is

[x-(-3)][x-(-3)]=0

⇒(x+3)^2=0

Finally, we will now find the product of these two quadratic equations to get the required bi-quadratic equation

⇒[(x-7)^2 - 4] [(x+3)^2]=0

⇒[x^2 + 49 - 14x -4] [x^2 + 9 + 6x]=0

⇒[x^2 + 45 - 14x] [x^2 + 9 + 6x]=0

⇒x^4 + 9x^2 + 6x^3 + 45x^2 + 405 + 270x - 14x^3 - 126x - 84x^2 = 0

⇒x^4 - 8x^3 - 30x^2 + 144x + 405 = 0

Hence, the required polynomial is x^4 - 8x^3 - 30x^2 + 144x + 405 = 0

When we compare ratios, equivalent ratios are the ones that don't change. In order to determine whether or not different ratios are equivalent, we compare them side by side. An example makes it clear that the ratios 1:2 and 2:4 are equivalent. With the aid of division and multiplication, we can determine the two equivalent ratios.

In order to create a ratio that is equal to one that is already given, we must multiply or divide the given ratio's two terms by a non-zero number.

1 cup of flour = 1/2 cup of water

4 cups of flour = 1/2 × 4

                       = 2 cups of water

1/2 cup of flour = 1/2 × 1/2

                          = 1/4 cups of water

2 cups of water = 4 cups of flour

1 cup of water = 4/2

                          = 2  cups of flour

3 cups of water = 2 × 3

The probability that Jay fails the final exam and passed the remedial exam is P(fail the final and passed the remedial) = 0.32.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given:

After giving the final exam, the professor found that many of his students failed the test, so he decided to give a remedial exam.

The probability that a student passes the final exam is 0.6. Given that a student fails the final exam, the probability that the student passes the remedial exam is 0.8.

We are given the following probabilities:

P(passes the final exam) = 0.6

P(fail the final exam = (1 - 0.6) = 0.4

P(passes through the remedial | failed the final) = 0.8

We have to find P(fail the final and passed the remedial).

P(fail the final and passed the remedial) = P(passes the remedial | failed the final)*P(failed the final)

P(fail the final and passed the remedial) = 0.8 x 0.4

P(fail the final and passed the remedial) = 0.32

Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables.

Given that the equation of a line is y = 4x - 2.

Parallel lines have the same slope. So, the slope of the new line is:

m = 4

Given that points (x1, y1) = (5, -11) are also in the new parallel line.
