Here, we want to know what the constant reveal

The growth factor inside the bracket as can be seen is greater than 1

It can also be less than 1

When it is greater than 1, there is an indication of a positive change from year to year

1.85 is greater than 1 and as such, we have an indication for a positive change

That means, as the years roll by, there will be a greater value of the quantity

Hence, as t increases, f(t) increases

To find the percentage growth rate, we subtract 1 from the growth value which is (1.85-1) = 0.85

0.85 represents a percentage of 85%; and thus there is a growth rate of 85% per year

Answer:

Quotient = x² - 3x + 5

Remainder = 9

Explanation:

To make the synthetic division, we need to rewrite the dividend with all the degrees of the exponents, so:

x³ - 4x + 6 = x³ + 0x² - 4x + 6

Then, we will use the coefficient of each term: 1, 0, -4 and 6

On the other hand, the divisor should have the form (x - a), so:

x + 3 = x - (-3)

Therefore, a = -3, and we will use this number for the synthetic division.

Finally, the synthetic division is:

Where the first number goes down, then the blue -3 is calculated as the number as 1 x -3, and the yellow -3 is equal to the sum of the number numbers 0 and -3, so: 0 + (-3) = -3

In the same way, 9 = -3 x -3 and 5 = -4 + 9

Finally, -15 = 5 x -3 and -9 = 6 - 15

Now, the coefficients 1, -3, and 5 give us the quotient of the division, and -9 is the remainder. So, the solution of the division is:

x = -0.6

The equation that represents this scenario is:

0.7x + 0.1*3 = 0.4(x + 3)

Solving for x, we have:

0.7x + 0.3 = 0.4x + 0.12

0.7x - 0.4x = 0.12 - 0.3

0.3x = -0.18

x = -0.18/0.3

= -0.6

Answer: x = -2 and y = -5

We are given two system of equations

-6x - 2y = 22 ---------------- equation 1

-12x + 10y = - 26------------- equation 2

These two system of equations can be solve simultaneously using elimination method

Before we can apply elimination method, we need to make one of the variables equal in both equations

Let us eliminate x

To make the co -efficient of x equal in both equations, Multiply equation 1 by 2 and equation 2 by 1

-6x - 2y = 22 * 2

-12x + 10y = -26 * 1

This becomes

-6x * 2 - 2y* 2 = 22*2

-12x*1 + 10y *1 = -26 * 1

-12x - 4y = 44------------------- equation 3

-12x + 10y = -26 --------------- equation 4

To eliminate x, substract equation 4 from equation 3

-12x - (-12x) - 4y - (10y) = 44 - (-26)

-12x + 12x -4y -10y = 44 + 26

0 - 14y = 70

-14y = 70

Divide both sides by -14

To find x, substitute the value of y = -5 into equation 1

-6x - 2y = 22

-6x - 2(-5) = 22

-6x + 10 = 22

-6x = 22 - 10

-6x = 12

Divide both sides by -6

Hence, x = -2, and y = -5 : (-2, -5)

Applying the Pythagoras Theorem, the length of RS = 8 units.

According to the figure,

Diameter = 16 +4 = 20 units

So, the Radius = Diameter/2 = 20/2 = 10 units

Now,

Let the center be M, then

MT = 10 - 4 = 6 units

RT = x units

The radius is perpendicular to the chord,

So, MTR will be a right-angled triangle,

We will apply the Pythagoras theorem,

So, we have :

[tex]RT^{2} +TM^{2} =RM^{2}[/tex]

Here, RT = x units

TM = 6 units and RM = radius = 10 units

Putting these values in the Pythagoras theorem,

[tex]x^{2} +6^{2} =10^{2}\\x^{2} + 36 = 100 \\x^{2} = 100 - 36 = 64\\x^{2} = 64 \\x = 8[/tex]

Thus, the length of RS = 8 units.

The area of the sector of the circle is about 0.3 dm².

A circle is a two-dimensional figure made up of points that are spaced out from a fixed point (center) on the plane by a fixed or constant distance (radius).

Given that, the radius of the circle is r = 0.5 dm and the angle of the sector is v = 135°

The sector area of the circle is given by:

A = (v/360°) × πr²

Substitute the values:

A = (135°/360°) × (3.14)(0.5)²

A = 0.375 × 3.14 ×0.25

A = 0.3

Hence, the area of the sector of the circle is about 0.3 dm².

After 5.94 sec it will reach at maximum height.

An algebraic equation of the second degree in x is a quadratic equation. Ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term, is the standard quadratic equation.

y = -16a² + 190x + 72

for maximum y value we need to find y'(x)

y' = -32x + 190

put y' = 0

-32x + 190 = 0

El camión con capacidad de 3 toneladas viajó 12 veces y el camión con capacidad de 4 toneladas viajó 11 veces.

En este problema encontramos dos camiones, uno de ellos con una capacidad de 3 toneladas y otro con capacidad de 4 toneladas, que desplazan 80 toneladas de madera en un total conjunto de 23 viajes. El total movido por cada camión es igual al producto del número de viajes y la capacidad de los camiones. Por tanto, el total desplazado de madera es igual a la siguiente ecuación:

3 · x + 4 · (23 - x) = 80

Donde x es la cantidad de viajes del camión de 3 toneladas de capacidad.

A continuación, despejamos la variable x:

3 · x + 4 · (23 - x) = 80

3 · x + 92 - 4 · x = 80

92 - x = 80

x = 92 - 80

Step-by-step explanation:

The sale price will be,

→ (600/100) × (100 - 25)

→ 6 × 75

→ $450

Now the final price will be,

→ 450 + ((450/100) × 5)

→ 450 + (4.5 × 5)

→ 450 + 22.5

→ $472.50

Hence, the price of $472.50.

The final price of the gaming system is $472.50, which is the correct answer would be option (B).

The percentage is defined as a ratio expressed as a fraction of 100.

A gaming system costs $600 and is on sale for 25% off. After the discount, there is a 5% tax.

To determine the final price of the gaming system, we need to first calculate the discount and then add the tax.

The discount is 25% of the original price, or 25% x $600 = $150.00.

So the price after the discount is $600 - $150 = $450.00.

The tax is 5% of the price after the discount, or 5% x $450 = $22.50.

Therefore, the final price of the gaming system is $450 + $22.50 = $472.50.
