To determine the total capacity of Goran's gas tank, we set up and solved an algebraic equation, finding that the total capacity of the tank is 18 gallons.

The student's question is about figuring out the total capacity of Goran's gas tank based on the information given. To solve this problem, we can set up a simple algebraic equation based on the proportions of the tank's capacity that are filled. Since filling the tank with 3 gallons of gas takes it from being 1/3 full to 1/2 full, we know that these 3 gallons represent the difference between 1/3 and 1/2 of the tank's total capacity.

Let's denote the total capacity of the tank as 'T' gallons. According to the question:

We can now set up the equation:

1/3 * T + 3 = 1/2 * T

To find 'T', we need to solve for T:

1/2 * T - 1/3 * T = 3

This simplifies to:
(3T - 2T) / 6 = 3
T/6 = 3

Now multiply both sides by 6 to solve for T:
T = 18

Therefore, the total capacity of Goran's gas tank is 18 gallons.

Answer:

4200

Step-by-step explanation:

In an arithmetic sequence equation t=a + (n-1)d, a is the starting value. In this case, a=3000.

Although, since the initial investment is not considered the first month, the equation is t = a + dn.

d is the rate of change. In this case, the rate of change is 100 for every month, n.

Substitute these values from the problem to get an equation:

t = 3000 + 100n

t means the total amount of money we have for the amount of months (n) that passed.

Sub n for 12.

t = 3000 + 100n

t = 3000 + 100(12)

t = 4200

You will have $4200 after 12 months of investment.

Answer:

Jewelry box:  1/6 yard

Step-by-step explanation:

4/5 (not 4\5) of her 5/6 yard goes into a dress:   (4/5)(5/6 yd) = 2/3 yard.

This is the same as 4/6 yard.  The amount of lace remaining, to be used on a jewelry box, is 5/6 - 4/6, or 1/6 yard.

Dawn used 1/6 yard of lace on the jewel box. This was calculated by subtracting the amount of lace used on the dress (2/3 yard) from the total lace available (5/6 yard).

The subject of your question pertains to Mathematics, specifically fractions and their applications. To find out how much lace Dawn used on the jewel box, we need to subtract the amount of lace used on the dress from the total amount of lace. Dawn has 5/6 yard of lace and she utilized 4/5 of it on the dress. To find out the part used on the dress in the same unit, multiply the total lace (which is 5/6) by the part used (which is 4/5), so (5/6)*(4/5) = 20/30 or 2/3 yard. To find out what part of the lace was used on the jewel box, subtract the dress lace from the total lace. So, 5/6 - 2/3 gives us 1/6 yard of lace that is used on the jewel box.

Answer:

ln|sec θ + tan θ| + C

Step-by-step explanation:

The integrals of basic trig functions are:

∫ sin θ dθ = -cos θ + C

∫ cos θ dθ = sin θ + C

∫ csc θ dθ = -ln|csc θ + cot θ| + C

∫ sec θ dθ = ln|sec θ + tan θ| + C

∫ tan θ dθ = -ln|cos θ| + C

∫ cot θ dθ = ln|sin θ| + C

The integral of sec θ can be proven by multiplying and dividing by sec θ + tan θ, then using ∫ du/u = ln|u| + C.

∫ sec θ dθ

∫ sec θ (sec θ + tan θ) / (sec θ + tan θ) dθ

∫ (sec² θ + sec θ tan θ) / (sec θ + tan θ) dθ

ln|sec θ + tan θ| + C

Answer:

option A (-1, 2.5) is correct

Step-by-step explanation:

Given

Let A(1, 1)

Let B(1, 4)

Let C(-3, 4)

Let coordinates of the circumcenter is (x, y)

Using distance formula

[tex]OA = OB[/tex]

[tex]OA^{2}=OB^{2}[/tex]

[tex](x-1)^{2}+(y-1)^{2} =(x-1)^{2}+(y-1)^{4}[/tex]

[tex]x^{2} +1-2x+y^{2} +1-2y=x^{2} +1-2x+y^{2} +16-8y[/tex]

[tex]8y-2y=16-1[/tex]

[tex]y=\frac{15}{6}[/tex]

[tex]y=2.5[/tex]

[tex]OA = OC[/tex]

[tex]OA^{2}=OC^{2}[/tex]

[tex](x-1)^{2}+(y-1)^{2} =(x-(-3))^{2}+(y-4)^{4}[/tex]

[tex](x-1)^{2}+(y-1)^{2} =(x+3)^{2}+(y-4)^{4}[/tex]

[tex]x^{2} +1-2x+y^{2} +1-2y=x^{2} +9+6x+y^{2} +16-8y[/tex]

[tex]-6x-2y-2x+8y=25-2[/tex]

put the y value in this equation

[tex]-8x+6\times\frac{15}{6} = 23[/tex]

[tex]-8x=23-15\\-8x=8\\x=-1[/tex]

So the coordinates of the circumcenter is (1, 2.5)

Midpoints: AB (1, 2.5), BC (-1, 4). Perpendicular bisectors: AB (y = 2.5), BC (x = -1). Intersection at (-1, 2.5), hence circumcenter is (-1, 2.5).

So, the correct answer is A. (-1, 2.5).

To find the circumcenter of a triangle, we can use the following steps:

1. Find the midpoints of two sides of the triangle.

2. Calculate the slopes of the perpendicular bisectors of those sides.

3. Use the midpoints and slopes to find the equations of the perpendicular bisectors.

4. Find the point of intersection of the perpendicular bisectors, which is the circumcenter.

Let's begin:

Given vertices of the triangle:

A (1, 1)

B (1, 4)

C (-3, 4)

1. Finding the midpoints of sides AB and BC:

Midpoint of AB = ((x1 + x2) / 2, (y1 + y2) / 2)

Midpoint of BC = ((x2 + x3) / 2, (y2 + y3) / 2)

Midpoint of AB = ((1 + 1) / 2, (1 + 4) / 2) = (1, 2.5)

Midpoint of BC = ((1 + (-3)) / 2, (4 + 4) / 2) = (-1, 4)

2. Calculate the slopes of the sides AB and BC:

Slope of AB = (y2 - y1) / (x2 - x1)

Slope of BC = (y3 - y2) / (x3 - x2)

Slope of AB = (4 - 1) / (1 - 1) = 3 / 0 (undefined slope)

Slope of BC = (4 - 4) / (-3 - 1) = 0 / -4 = 0

The slope of AB is undefined because the difference in x-coordinates is zero, meaning it's a vertical line. For a perpendicular bisector, we need to take the negative reciprocal of this slope.

3. Calculate the negative reciprocals of the slopes of AB and BC:

Negative reciprocal of undefined slope = 0

Negative reciprocal of zero slope = undefined

4. Equations of the perpendicular bisectors:

For AB: The perpendicular bisector passes through the midpoint (1, 2.5) and has a slope of 0.

Using the point-slope form of a line equation: y - y1 = m(x - x1)

y - 2.5 = 0(x - 1)

y = 2.5

For BC: The perpendicular bisector passes through the midpoint (-1, 4) and has an undefined slope (vertical line).

So, the equation is x = -1.

Now, we find the point of intersection of the perpendicular bisectors.

The point of intersection is the circumcenter.

Since the perpendicular bisectors intersect at (-1, 2.5), which is the midpoint of AB, the circumcenter is at (-1, 2.5).

So, the correct answer is A. (-1, 2.5).

Answer:

The future value of investment at 6 % compounded quarterly is                $ 4782.472

Hopes this helps

if not then I'm sorrr

The quotient in simplified form for \(\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}\) is \(-\frac{3p^8}{4q^3}\). This is found by dividing the numerical coefficients and subtracting the exponents for variables of the same base (negative exponents indicate reciprocals).

To find the quotient in simplified form for \(\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}\), we perform division of the coefficients (15 divided by -20) and subtraction of the exponents for variables with the same base (p's and q's exponents) according to the rules of exponents. First, simplify the numerical coefficients:

\(\frac{15}{-20} = -\frac{3}{4}\)

Now, subtract the exponents for p (applying the formula x^p \cdot x^q = x^{(p+q)}):

\(p^{-4} - p^{-12} = p^{-4 + 12} = p^8\)

Next, apply the same process to the exponents of q:

\(q^{-6} - q^{-3} = q^{-6 + 3} = q^{-3}\)

Combine the results to get the simplified quotient:

\(-\frac{3}{4} × p^8 × q^{-3}\)

Remember that a negative exponent indicates a reciprocal, so we can write \(q^{-3}\) as \(\frac{1}{q^3}\). Therefore, the final answer is:

\(-\frac{3p^8}{4q^3}\)

Answer:

f(n + 1) = –0.5f(n)

Step-by-step explanation:

The terms 9.6, –4.8, 2.4, –1.2, 0.6 alternate negative and positive. This means they must have a negative rate of change (because multiplying with negatives give both positive and negative numbers).

This narrows it down to:

f(n + 1) = –0.5f(n)

f(n + 1) = f(–0.5n)

Substitute f(n) for f(1)=9.6.

f(n + 1) = –0.5(n)

f(1 + 1) = –0.5(1)

f(2) = –0.5(9.6)

f(2) = -4.8

Since the second term is -4.8, f(n + 1) = –0.5f(n) is the recursive formula.
