Answer:

Step-by-step explanation:

 let us apply the interpolation formula to solve this problem

we have

\(\frac{y-y1}{x-x1} =\frac{y2-y1}{x2-x1}\)

Now let us set the values to the notation above

x= $1.20

x1= $2.20

x2= $1.50

y = 50 cones

y1= 30 cones

y2= ?

\(y2= \frac{(y-y1)}{(x-x1)} (x2-x1)+y1\)

Substituting our given data we have

\(y2= \frac{(50-30)}{(1.2-2.2)} (1.5-2.2)+30\\\\y2= \frac{20}{-1} (-0.7)+30\\\\y2= (20*0.7)+30\\y2= 14+30\\y2= 44\)

the demand at a price of $1.50 per cone is 44 cones

Answer:

a) The equation has the greatest slope.

Step-by-step explanation:

The table has the values as shown below;

x    y

1    3

2   6

3   9

The gradient of the line can be found as;

m=Δy/Δx

m= 9-3 /3-1

m= 6/2

m₁= 3

The equation of the other line is :   y=4x

The gradient is , m₂ = 4

The presentation with the greatest slope is the equation that has a slope of 4.

The two roots are

\(\alpha = -8+3i,~~~ \beta = -8-3i\\\\\\x^2 - (\alpha + \beta)x + \alpha \beta = 0\\\\\implies x^2 - (-8+3i-8-3i)x + (-8+3i)(-8-3i)=0\\\\\implies x^2 +16x + (-8)^2+3^2 =0\\\\\implies x^2 +16x +64+9=0\\\\\implies x^2 +16x +73\)

Hence the answer is D.

Answer:

The last one \((x=11.3, y=8)\).

Step-by-step explanation:

1) There are three trigonometric ratios for right-angled triangles.

\(sin()=\frac{opposite}{hypotenuse}\\cos()=\frac{adjacent}{hypotenuse}\\tan()=\frac{opposite}{adjacent}\)

In a right triangle, the hypotenuse, h, is the side opposite the right angle. Relative to the acute angle θ, check the attachment, the legs are called the opposite side, o, and the adjacent side a.

2) In this case, we are given a length and an angle to find x and y.

Let's find x first. To find x we need to use \(sin()=\frac{opposite}{hypotenuse}\).

\(sin(45)=\frac{8}{x}\\sin(45)x=8\\x=\frac{8}{sin(45)} \\x=11.31\)

Find y.

Notice that, we can use the Pythagorean Theorem \((c^2=a^2+b^2)\) to find y.

\(c^2=a^2+b^2\)

\(11.31^2=8^2+b^2\\11.31^2 - 8^2 = b^2\\63.9161 = b^2\\\sqrt{63.9161} = b\\b = 7.99\)

3) Round them off to the nearest tenth.

\(x=11.31\\x=11.3\)

\(y=7.99\\y=8\)

Therefore, the correct choice is the last one \((x=11.3, y=8)\).

The firm's federal income tax is $57,168.

To calculate the firm's federal income tax, we need to determine its taxable income first. Taxable income is calculated by subtracting deductions from the firm's total income.

In this case, the firm's total income consists of income from operations, interest income, and dividend income.

Total income:

Income from operations = $231,000

Interest income = $23,100

Dividend income = $29,700

Total income = $231,000 + $23,100 + $29,700 = $283,800

Next, we deduct expenses from the total income. In this case, the only relevant expense is the interest paid to bondholders:

Total expenses = Interest paid to bondholders = $11,000

Taxable income = Total income - Total expenses = $283,800 - $11,000 = $272,800

Now, we can calculate the federal income tax by applying the federal tax rate of 21% to the taxable income:

Federal income tax = Taxable income * Federal tax rate

Federal income tax = $272,800 * 0.21 = $57,168

Therefore, the firm's federal income tax is $57,168.

The solution to the system of equations is x = 1 and y = -3.

To solve the system of equations using the substitution or elimination method, let's start with the substitution method.

Given equations:

y = 4x - 7

4x + 2y = -2

We'll solve equation 1) for y and substitute it into equation 2):

Substituting y from equation 1) into equation 2):

4x + 2(4x - 7) = -2

4x + 8x - 14 = -2

12x - 14 = -2

Now, we'll solve this equation for x:

12x = -2 + 14

12x = 12

x = 12/12

x = 1

Now that we have the value of x, we can substitute it back into equation 1) to find y:

y = 4(1) - 7

y = 4 - 7

y = -3

Therefore, the solution to the system of equations is x = 1 and y = -3.

Answer: I think it is false...

Answer:

The first term of the sequence is:

Step-by-step explanation:

Given the sequence

aₙ = (-1)ⁿ · 3n²

substituting n = 1 to determine the first term

a₁ = (-1)¹ · 3(1)²

a₁ = (-1)¹ · 3(1)²

Applying the exponent rule: \(a^1=a\)

a₁ = -1 · 3(1)

a₁ = -1 · 3

a₁ = -3

substituting n = 2 to determine the 2nd term

a₂ = (-1)² · 3(2)²

a₂ = 1 · 3(4)

a₂ = 12

substituting n = 3 to determine the 3rd term

a₃ = (-1)³ · 3(3)²

a₃ = -1 · 3(9)

a₃ = -1 · 27

a₃ = -27

substituting n = 4 to determine the 4th term

a₄ =  (-1)⁴ · 3(4)²

a₄ = 1 · 3(16)

a₄ = 1 · 48

a₄ = 48

Therefore, the first term of the sequence is:

The tip was  17.73% of the original bill.

Percent is the value which indicate hundredth part of the quantity .

For Example : 50/100 represents 50%.

It is given in the question that

Bill for dinner  = $55.21

Tip given = $9.79

Tip percentage can be calculated using

Tip percent = (tip given / total bill) * 100

Tip percent = (9.79/55.21) * 100

= 0.1773 * 100

=============================================================

Explanation:

What we need to do is first find out how many multiples of 7 are between 50 and 150.

Divide 50 over 7 to get 50/7 = 7.1 approximately. So we can see that 7*7 = 49 and 7*8 = 56. This shows that 56 is the smallest such multiple of 7 between 50 and 150.

We'll do the same for 150. So, 150/7 = 21.4 approximately which means 7*21 = 147 and 7*22 = 154

The multiples of 7 between 50 and 150 are: {56, 63, ..., 147}

We can rewrite that list into {7*8, 7*9, ..., 7*21}

For each multiplication, we have 7 times something. That "something" is in the list {8, 9, ..., 21} in which we see there are 21-8+1 = 14 items here. I used the formula b-a+1 to count the number of whole numbers from 'a' to b, including both endpoints.

In short, there are 14 multiples of 7 between 50 and 150.

That would be the final answer if we weren't worried about ignoring multiples of 4.

However, what we need to do now is look at the list {8, 9, ..., 21} and see which of those are multiples of 4. That sub-list is {8, 12, 16, 20} and those values will be kicked out. So we'll go from 14 multiples of 7 to 14-4 = 10 multiples of 7.

The implicit general solution is 0.5y² = -0.5x² + 0.5x + C, here C should pass through the origin of the circle. The family of curves (T)  represents the integral curve. The graph (T) is represented below.

a. To find the implicit general solution of the given differential equation, we can integrate both sides with respect to x. Let's start by rewriting the equation:

yy' = -x + 1/2

Integrating both sides:

∫ yy' dx = ∫ (-x + 1/2) dx

Using integration by parts on the left side, let u = y and dv = y' dx:

\(\int u dv = uv - \int v du\\\\y\int dy = \int (-x + 1/2) dx\\\\1/2 y^2 = -1/2 x^2 + 1/2 x + C\\\\0.5y^2 = -0.5x^2+0.5x+C\)

Where C is the constant of integration. This is the implicit general solution of the given differential equation.

b. The family of curves (T) that represents the general solution in an orthonormal system is known as the integral curves of the differential equation.

c. To find the graph (T) that passes through the origin O(0, 0), we substitute the point (x, y) = (0, 0) into the implicit general solution and solve for C:

\(1/2(0)^2 = -1/2(0)^2 + 1/2(0) + C\\\\0 = 0 + 0 + C\\\\\C = 0\)

So the graph (T) that passes through the origin is given by:

\(1/2 y^2 = -1/2 x^2 + 1/2 x\)

This equation represents the specific curve that satisfies both the differential equation and the condition of passing through the origin.
