3x - y = -9
−2x + 2y = 6

Answer:

-x² -10x -26

Step-by-step explanation:

Substitute x in f(x) with x + 5:

f(g(x)) = - (x+5)² - 1

= - (x² + 10x + 25) -1

= -x² -10x -25 -1

= -x² -10x -26

The given equation after a translation by 2 units upwards is y = 3.5x + 2.

The rules for translating an equation in both vertical and horizontal directions are:

The given equation is y = 3.5x

The equation after translation by 2 units upward is obtained by using the rule we have y = f(x) + m.

⇒ y = 3.5x + 2

The graphs for the given equation and the translated equation are shown in the graph below.

For the pair that show translation in both equations, substituting x = 0, we get

y = 3.5x ⇒ y = 3.5(0) = 0; So, the point is (0,0)

and

y = 3.5x + 2 ⇒ y = 3.5(0) +2 = y = 2; So, the point (0,2)

Therefore, the required pair is (0,0) and (0,2).

A split infinitive is a common grammatical mistake that can be hard for writers to spot. Many people think they are not a big deal, but they can often have a major impact on your writing and make it hard for a reader to understand what you have to say.

Step-by-step explanation:

Take, for example, this sentence:

I like to on a hot day eat a lot of ice cream.

Did you have to read it twice to be clear what it was saying? I know I did. But let's make just a little adjustment:

On a hot day, I like to eat a lot of ice cream.

The measure of the perpendicular of the right-angle triangle will be 16.728 units.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

The sine of the angle is the ratio of perpendicular to the hypotenuse.

sin θ = Perpendicular / Hypotenuse

The angle is 42° and the measure of Hypotenuse is 25. Then the measure of the side 'x' will be given as,

sin θ = Perpendicular / Hypotenuse

sin 42° = Perpendicular / 25

Perpendicular = 25 x sin 42°

Perpendicular = 16.728

The measure of the perpendicular of the right-angle triangle will be 16.728 units.

( x - 1 ) is the factor of f(x) as remainder is 0

A polynomial is a mathematical statement made up of coefficients and indeterminates that uses only the operations addition, subtraction, multiplication, and powers of positive integers of the variables.

According to the given information

The given polynomial is

f(x) = [tex]x^{3} + 4x^{2} +x -6[/tex]

According to the remainder theorem

( x - 1 ) will be the factor of f(x) , if f(1) is zero

The required demand function for the marginal revenue function is P = 0.02x² - 0.025x.

Marginal Revenue is the revenue that is gained from the sale of an additional unit. It is the revenue that a company can generate for each additional unit sold; there is a marginal cost attached to it, which must be accounted for.

The marginal revenue function, find the demand capability is P = 0.02x² - 0.025x + 138 when R'(x) = 0.06x² - 0.05x + 138 .

Considering that,

We need to find for the peripheral income capability, find the interest capability.

Recollect that the pay is zero assuming no things are sold:

R'(x) = 0.06x² - 0.05x + 138

p(x) is what.

That's what we know,

MR = dTR/dx = 0.06x² - 0.05x + 138

Incorporating the marginal revenue function , we get complete income capability,

MR = TR

= (0.06x²⁺¹)/(2+1) - (0.05x¹⁺¹)/(1+1) + 138x

= (0.06x³)/3 - (0.05x²)/2 + 138 x

TR = 0.02 x³ - 0.025 x² + 138 x

TR = (P)(Q) = (P)(x) = 0.02 x³ - 0.025 x² + 138 x

P = ( 0.02 x³ - 0.025 x² + 138 x)/x

P = 0.02x² - 0.025x + 138

In this manner, The marginal revenue function, find the interest capability is P = 0.02x² - 0.025x + 138 when R'(x) = 0.06x² - 0.05x + 138 .

What is the combination?

A combination in mathematics is a choice made from a group of separate elements where the order of the selection is irrelevant.

Here, we have

A teacher selects 7 students from her class of 27 students.

We have to find how many ways are there for her to select the students of the chosen students.

The order of selecting the students does not matter here so the number of ways to select 7 students from the class of 27 to work together on a project is:

C(27,7) = 27!/(7!*(27-2)! = 888030

The reasoning above makes it very evident that the hyperbola's coordinate is (8, -1)

The hyperbola is open upward and downward because the expression 'y' has a positive leading coefficient. In comparison to the usual equation, the hyperbola's center is found to be at (2, -1) and its 'a' point, 6, and 'b' point is 8. A smooth curve that lies in a plane and is classified as a hyperbola in mathematics by either its geometric characteristics or by equations for which it is the solution set. Two parts of a hyperbola, referred to as connected components or branches, are mirror reflections of one another and resemble two infinite bows.

Given,

((x-2)²/36)-((y+1)²/64)=1

We know that the standard form of a parabola is:

The slope is the measure of the steepness and direction of a line. You can predict whether lines in a coordinate plane are parallel, perpendicular, or none by finding the slope of the lines.

There are two distinct points on any line that can be used to calculate its slope. Between two distinct points on a line, the slope formula calculates the ratio of vertical and horizontal changes. In mathematics, the slope is calculated as the ratio of the rise to the run, or as the rise divided by the run. The slope is a measure of how steep a line is in a coordinate plane.

A function's or relation's domain is the set of all possible independent values that the relation can take. It is the sum of all possible inputs.

A function's or relation's range is the set of all possible dependent values that the relation can produce from the domain values. It is the sum of all possible outputs.

When dealing with sets of ordered pairs, we simply divide the pairs into x- and y-coordinates. The domain is formed by the x-coordinates, which are independent values. The y-coordinates are the dependent values, i.e. they define the range.The domain in the set of ordered pairs {(a,b); (c,d); (e,f); (g,h)} is the set of the first number in each pair (those are the x-coordinates): {a,c,e,g}. The range is the set of all the pairs with the second number (the y-coordinates): {b,d,f,h}.

Given,

The set of ordered pair =   {(-1,5) , (2,3), (33,6), (32,7)}

Based on the observations above, it is clear that an appropriate domain for the function is x ≥ - 2.

Functions and values given the function that represents elevation, in feet, of Jayden hikes expressed as:

f(x)=(x+2)²+250.

If the domain value of the function is -4, then;

The principal investment required to get a total amount of $17,757.16 from compound interest at a rate of 3.9% per year compounded continuously over 9 years is $12,500.75.

What is continuous compounding?

There is no cap on how frequently interest can accumulate thanks to continuous compounding. A balance can compound continuously an unlimited number of times, which means interest is earned on it constantly.

We have,

9 years in an account with a 3.9% annual interest rate compounded continuously,

an investment is worth a total of $17,757.16.

First, convert R as a percent to r as a decimal

r = R/100

r = 3.9/100

r = 0.039 per year,

Then, solve the equation for P

P = A / ert

P = 17,757.16 / e(0.039*9)

P = $12,500.75

Hence, the principal investment required to get a total amount of $17,757.16 from compound interest at a rate of 3.9% per year compounded continuously over 9 years is $12,500.75.
