Answer:

$27

Step-by-step explanation:

Simple interest is a way of calculating the interest charge on a loan or investment. It is calculated by multiplying the principal amount by the interest rate and the time period. In your example, the simple interest calculation would be $225 * 6% * 2 years = $27.

Answer:

Simple interest is a type of interest that is calculated only on the principal amount of a loan or investment, without taking into account any additional interest that has been earned on the principal. To calculate simple interest, you multiply the principal amount by the interest rate and the length of time the interest is being applied. For example, if you have a principal of $225, an interest rate of 6%, and a time of 2 years, the simple interest would be calculated as follows:

$225 x 6% x 2 years = $27.

In this case, the simple interest on the $225 principal would be $27. This means that after 2 years, you would owe $252 in total, including the original principal and the interest that has been earned on it. Simple interest is typically used for short-term loans or investments, where the interest is paid or earned at regular intervals, such as monthly or annually.

An expression that represents the ADDITION of the two number lines is: B. -10x - 5x + 30x.

Each segment equals 5x and the first arrow is 30x long.

In Mathematics, a number line can be defined as a type of graph with a graduated straight line which comprises both positive and negative numbers that are placed at equal intervals along its length.

This ultimately implies that, a number line primarily increases in numerical value towards the right from zero (0) and decreases in numerical value towards the left from zero (0).

Based on the number line shown above, we can reasonably infer and logically deduce that each of its segment is equal to 5x with the longest arrow measuring 30x on the number line.

The polygon ABCD is transformed 4 units to the left after being reflected across the x-axis.

The transformation of a function may involve any change.

Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

Reflect the polygon ABCD across the x-axis as;

A(x, y) → A'(x, -y) (x, -y) (x, -y)

According to this rule, A's coordinates are

A(1, -5) →  A'(1, 5) (1, 5) (1, 5)

ABCD is shifted 4 units further to the left.

Now apply to the translation:

A"(x - 4, y) = A'(x, y) (x - 4, y)

A'(1, 5) → A"(1 - 4, 5) (1 - 4, 5) (1 - 4, 5)

→ A"(-3, 5) (-3, 5) (-3, 5)

Thus Polygon ABCD will eventually overlap Polygon A'B'C'D' through a series of transformations.

The parabola's vertex is (-3/2, -22). Because this is the lowest point on the parabola, the function's minimum value is -22.

To determine the maximum or minimum value of the quadratic function y = 2x² + 12x + 5, you need to find the vertex of the parabola formed by this function.

To find the vertex of the parabola, you can use the formula x = -b / (2a), where x is the x-coordinate of the vertex, a is the coefficient of the x² term, and b is the coefficient of the x term.

In this case, the coefficient of the x² term is 2, and the coefficient of the x term is 12. Therefore, the x-coordinate of the vertex is x = -12 / (2×2) = -6 / 4 = -3/2.

To find the y-coordinate of the vertex, you can substitute the x-coordinate back into the original equation:

y = 2(-3/2)² + 12(-3/2) + 5 = 2(-9/4) + (-18) + 5 = -9 + (-18) + 5 = -22.

Therefore, the vertex of the parabola is (-3/2, -22). This is the lowest point on the parabola, so the minimum value of the function is -22.

A polynomial function of least degree with rational coefficients so that P(x) = 0 has the given roots is P(x)=x²-5x-14

A function is said to as polynomial when a variable in an equation, such as a quadratic equation or cubic equation, etc., has only positive integer exponents or non-negative integer powers. One polynomial with an exponent of 1 is 2x+5, for instance. One that has more than two algebraic terms is referred to as a polynomial expression. Polynomial is a monomial or binomial that is repeatedly added, as the name suggests.

A mathematical expression containing one or more algebraic terms, where each algebraic term is made up of a constant multiplied by one or more variables raised to a nonnegative integral power.

x= -2, x=7

Given,

P(x) = 0

This polynomial function has the roots,

The wheel will travel 904.32 inch when it take 4 rotation

How do you calculate distance using radius and revolutions?

Hint: To calculate the wheel's circumference, use the formula 2πr, where r is the radius and π=3.14 , to first determine the distance covered in one revolution. To determine the distance traveled, multiply the distance covered in one revolution by 200. In the end, multiply it by 100 to get the distance in meters.

In mathematics, what is the circumference?

The distance between the center of the sphere and any plane passing through it is known as the circumference. Any large circle that passes through a point known as a pole is called a meridian.

The circle's circumference must be known in order to compute the distance covered during one rotation. C=2πr is the formula for the circumference.

The radius, designated as r, is 36 inches. As a result, C=2π36 = 72π. The distance covered in one rotation is 226.08 inches because (pi) =3.14159, C=226.08 inches. So when we rotate this 4 times the it travels 226.08 * 4 = 904.32 inch

The probability that the Yankees will lose when they score 5 or more runs is equal to 0.2766.

What is Conditional Probability?

From the question, we know that the probability that the Yankees will win a game is 0.53.

[tex]\implies P(W)=0.53[/tex]

Also, then the probability that the Yankees will lose a game is given as,

[tex]P(L)=1-P(W)\\\implies P(L)=1-0.53\\\implies P(L)=0.47[/tex]

It is also given that, the probability that the Yankees will score 5 or more runs is 0.48.

[tex]\implies P(A)=0.48[/tex]  -----(1)

So, the probability that the Yankees will score less than 5 runs is,

[tex]P(S)=1-P(A)\\\implies P(S)=1-0.5\\\implies P(S)=0.5[/tex]------(2)

We also know the probability that the Yankees will win and score 5 or more runs is 0.42.

[tex]\implies P(B)=0.42[/tex]

Also, then the probability that the Yankees will lose or score less than 5 runs is given as,

[tex]P(C)=1-P(B)\\\implies P(C)=1-0.42\\\implies P(C)=0.58[/tex]

Next, the probability that the Yankees will lose and score less than 5 runs is,

[tex]P(D)=0.42+0.5-0.58\\\implies P(D)=0.34[/tex]

Now, the required probability is the probability that the Yankees will lose and score 5 or more runs.

It can be calculated using the conditional probability formula, [tex]P(M/N)=\frac{P(M\cap N)}{P(N)}[/tex]

So, the required probability  that the Yankees will lose and score 5 or more runs is given as,

P(they score 5 or more runs / probability that they lose game) = P(they lose and score 5 or more runs) / P(they lose the game)

[tex]\implies P(E)=\frac{0.47-0.38}{0.47} \\\implies P(E)=0.2766[/tex]

Therefore, the probability that the Yankees will lose when they score 5 or more runs is equal to 0.2766.
