The formula for a cubic polynomial function is f(x)=ax³++bx²+cx+d, where a not equal to 0.

f(x) = x³+2x²-16x-32

The formula for a cubic function is f(x) = ax3 + bx2 + cx + d, where a, b, c, and d are all real values and a 0.

A cubic polynomial function has the formula f(x)=ax3++bx2+cx+d, where an is not equal to 0. A cubic polynomial always has three zeros, which could be all the same or all different. The zeros could be real or complex, depending on the function.

If x = -4, -2, or 4 then f(x) = 0

These are the roots, then.

factors include F(x) = [(x+4)(x-4)] = (x+4)(x+2)(x+4) For example, (x+2) f(x) = (x2-16) (x+2) f(x) = x3+2x2-16x-32

A cubic equation might have three real roots, similar to how a quadratic equation could have two. However, a cubic equation always has at least one real root, unlike a quadratic equation, which may not have any real solutions.

What is simple interest?

A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest. Now, before exploring the idea of basic curiosity in further detail,

The formula for simple interest is:

S = p*t*r/100

where P is the principal amount of money, R is the interest rate as a decimal, T is the time.

We'll figure out how to solve the two-equation linear system:

We'll set x equal to 8% of the investment and y equal to 5% of the investment.

Equation 1: x + y = 2900 (total invested money)

Equation 2: 0.06x + 0.04y = 138 (total interest of both investments)

25*(0.06x+0.04y = 138)

Equation 3: 1.5x + y = 3450

Eq3-Eq1

0.5x = 550

x = 550/0.5 = 1100

Hence the investment in each year will be $1100.

The expression as the logarithm of a single number or expression is log( x⁵.y/z⁶).

A logarithm is a multiplication-based mathematics notion.

The exponent that will result in a particular value is a logarithm.

An exponent or power with which a base must be increased in order to produce a particular number.

If bˣ = n, then x is the logarithm of n here to base b, which is expressed mathematically as x = logb n. For instance, 2³ = 8; hence, 3 is the base-2 logarithm of 8 or 3 = log₂ 8.

For the stated question;

= 5log x + 2logy - 6logz

Using the addition, division and power property.

log(m x n) = log m + log n

log(m/n) = log m - log n

= log x⁵ + logy² - logz⁶

= log( x⁵ ₓ y²) - logz⁶

= log( x⁵.y/z⁶)

Thus, the expression as the logarithm of a single number or expression is log( x⁵.y/z⁶).

The graph of the function denotes a straight line which passes through the points (-1 , 0) and (0 , -2) .

The graph of the function denoted as y = -2x - 2 is in the form of a straight line as it can be written as y = mx + c the slope is -2 and y intercept is at (0,-2).

The graph of the line passes through :

At x=0 , y = -2

At x = -1 , y = 0

At x = 2 , y = -6

The line passes through (0,-2) , (-1,0) and (2,-6) .

A straight line is a line with no curves and an infinite length. Any two locations can also be connected by a straight line, but its endpoints must extend into the infinite.

A straight line results from connecting two points A (x1, y1) and B (x2, y2) along the shortest path possible and stretching the endpoints of the line to infinity.

For mutually exclusive events R₁,R₂ and R₃, the value of P(R₁Q) is 3/55.

Two events are said to be mutually exclusive in probability theory if they cannot happen simultaneously or at the same time. In other terms, occurrences that are mutually exclusive are referred to as discontinuous events. If two occurrences are regarded as separate ones, there is no chance that they will happen at the same moment. Two events are mutually exclusive or disjoint in logic and probability theory if they cannot both occur at the same time. The results of a single coin flip, which can result in either heads or tails but not both, serve as an obvious illustration.

Given,

Events:

P(R₁) = 0.05 P(R₂) = 0.6

For P(R₁ /Q)

P(R₁Q)

mutually exclusive event:

P(Q/R₁)P(R₁)/P(Q/R₁)P(Q₁) + P(Q/R₂)P(R₂) + P(Q/R₃)P(R₃)

How to solve a quadratic equation using the Quadratic Formula.

6y² + 5y - 4

using the Quadratic Formula where a = 6, b = 5, and c = -4

y =−b±(√b2−4ac) / (√2a)

y =−5±(√5²−4(6)(−4)) / √(2(6))

y =−5±(√25−(−96)) / √12

y =−5± (√121 / √12

What is Frequency Tree?

Frequency trees display the real frequency of certain events. They can display the same data as a two-way table, but frequency trees are more readable since they illustrate the frequency hierarchy. Probability trees depict the likelihood of a series of occurrences.

Solution:

From the question, we can see the there are 120 people in the theatre.

Since, there are 72 females in the theatre we can find the total number of males by 120-72 = 48

Also, the male who purchased Ice Cream were 36 therefore, the males who did not purchased Ice Cream are 48-36 = 12

And, the females who purchased Ice Cream are 41. So, the female who did not purchased Ice Cream are 72 - 41 = 31

Answer:

mAngleB = 67°

Step-by-step explanation:

The angle marked 15x is made by extending one side of the triangle. That is an exterior angle (like, its outside the triangle)

There are two angles inside the triangle that are away from that exterior angle. They are called remote interior angles. They are marked 83° and 6x+7 in this question.

Here's the rule:

If you add up the two remote interior angles it equals the exterior angle.

83° + 6x + 7 = 15x

Subtract 6x.

83 + 7 = 9x

Simplify.

90 = 9x

Divide by 9.
