Step-by-step explanation:

solution given:

[tex]\frac{3}{4} *8\frac{1}{2}[/tex]

let make mixed fraction to normal fraction

[tex]8\frac{1}{2} =\frac{8*2+1}{2} =\frac{17}{2}[/tex]

[tex]\frac{3}{4} *\frac{17}{2}[/tex]

in multplication fraction, we multiply numerator to numerator and denominator to denominator.

[tex]\frac{3}{4} *\frac{17}{2}=\frac{3*17}{4*2} =\frac{51}{8}[/tex]

again

in mixed fraction =[tex]6\frac{3}{8}[/tex]

Marginal Revenue is negative, the firm should consider reducing its output to increase its total revenue.

Therefore, correct answer will be a. increase.

Marginal Revenue (MR) is a crucial concept in economics that measures the change in a firm's total revenue as a result of selling one additional unit of output. MR is used by firms to make decisions about how much output to produce and what price to charge.

In a linear (inverse) demand function, MR is negative when the elasticity of demand is less than one, meaning that the demand for a product is relatively inelastic. In other words, as the firm increases output, the price will decrease, causing total revenue to decline.

The value of x is 15

The value of y is 7.

The unknown sides:

x = 15

5y - 3 = 33

y + 9 = 16

x - 2 = 13

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Similar triangles mean the ratios of the corresponding sides are equal.

Now,

(5y - 3)/(y + 9) = 30/x = 26/(x - 2)

Taking two ratios.

(5y - 3)/(y + 9) = 30/x

5xy - 3x = 30y + 270

Taking two ratios.

30/x = 26/(x - 2)

30x - 60 = 26x

30x - 26x = 60

4x = 60

x = 15

Now,

Substituting x = 15

5xy - 3x = 30y + 270

5 x 15 x y - 3 x 15 = 30y + 270

75y - 45 = 30y + 270

75y - 30y = 270 + 45

45y = 315

y = 7

Now,

x = 15

5y - 3 = 35 - 3 = 33

y + 9 = 7 + 9 = 16

x - 2 = 15 - 2 = 13

Thus,

x is 15 and y is 7.

The unknown sides are 15, 33, 16, and 13.

The curvature of a curve r(t) = 9t i 7t j (2 t2) k is 4 × ||9 i + 7 j|| / (9² + 7² + 4t²)^(3/2).

Curvature is a measure of the amount by which a curve deviates from being straight. It describes the degree to which a curve bends or twists at any point along its length.

In mathematics, curvature is a property of curves and surfaces that is used to describe their shape and local behavior. For example, the curvature of a circle is constant and is equal to the reciprocal of its radius. The curvature of a straight line is zero.

Curvature is a scalar quantity and is usually measured in units of inverse length, such as 1/meter. There are several ways to mathematically define and calculate curvature, including the concept of the curvature of a curve at a point, which is the rate of change of the direction of the tangent to the curve at that point.

The curvature of a curve is given by:

k(t) = ||r'(t) x r''(t)|| / ||r'(t)||³

where r'(t) is the first derivative of r(t), r''(t) is the second derivative of r(t), and || || is the magnitude or length of a vector.

Given the curve r(t) = 9t i + 7t j + (2 t²) k, we can find its first and second derivatives:

r'(t) = 9 i + 7 j + 4t k

r''(t) = 4 k

So, the curvature of the curve r(t) is:

k(t) = ||r'(t) x r''(t)|| / ||r'(t)||³ = ||9 i + 7 j|| × ||4 k|| / ||9 i + 7 j + 4t k||³ = 4 × ||9 i + 7 j|| / (9² + 7² + 4t²)^(3/2)

Since this expression depends on t, the curvature is a function of t, not a constant.

Answer:

4 is there answer I think

Step-by-step explanation:

Using the Taylor Remainder Theorem, the values of x ≤ 1.2145 for which this approximation is within 0.004458 of the right answer.

The function is f(x) = cos(x) at a=0.

The Taylor Series is:

f(x) = f(a) + f'(a)/1! (x - a) + f''(a)/2! (x - a)^2 + f'''(a)/3! (x - a)^3 + .............

Now, d/dx (cosx) = -sinx at a = 0

d/dx (cosx) = 0

d^2/dx^2 (cosx) = -cosx at a = 0

d^2/dx^2 (cosx) = -1

d^3/dx^3 (cosx) = sinx at a = 0

d^3/dx^3(cosx) = 0

d^4/dx^4 (cosx) = cosx at a = 0

d^4/dx^4 (cosx) = 1

d^5/dx^5 (cosx) = -sinx at a = 0

d^5/dx^5 (cosx) = 0

d^6/dx^6 (cosx) = -cosx at a = 0

d^6/dx^6 (cosx) = -1

Now putting the value

f(x) = 1 + 0/1! (x - 0) + (-1)/2! (x - 0)^2 + 0/3! (x - 0)^3 + 1/4! (x - 0)^4 + 0/5! (x - 0)^5 + (-1)/6! (x - 0)^6 + .............

Simplifying

f(x) = 1 - 1/2! x^2 + 1/4! x^4 - 1/6! x^6 + .............

|1/6! x^6| ≤ 0.004458

Multiply by 6! on both side, we get

x^6 ≤ 0.004458 × 6!

x ≤ 1.2145

There are 5 inches between the two picnic areas on the map. Therefore, option A is the correct answer.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

=[tex]\begin{bmatrix}-4 \\ -8 \\ 7\end{bmatrix}[/tex]

We can solve for the unknowns [tex]$x_1$, $x_2$, and $x_3$[/tex]  by using the Gaussian elimination method. The first step is to subtract 3 times the first equation from the second equation, and the result is

[tex]\begin{bmatrix}1 & -3 & 4 \\ 0 & -10 & 15 \\ -4 & 6 & -1\end{bmatrix}\begin{bmatrix}x_1 \\ x_2 \\ x_3\end{bmatrix}[/tex]

[tex]=\begin{bmatrix}-4 \\ -20 \\ 7\end{bmatrix}[/tex]

We can then subtract 4 times the first equation from the third equation, and the result is

Since the numerator is missing, you want to multiply the denominator onto the other side.

5 x 7 =35

x=35

Answer:

x=35

Step-by-step explanation:

Easy way to solve is making x/5 an improper fraction (fraction whose numerator is equal to or greater than its denominator.)

How I solved it was by multiplying 7×5=35, then I plugged the value into x making it (35/5)=7.

Now just make it a proper fraction, 35÷5=7, now we have 7=7.

Answer:

Step-by-step explanation:

The slope of a line can be found using the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are two points on the line. Plugging in the given points, we get:

slope = (8 - 6) / (-5 - (-10)) = 2 / 5 = 0.4

So the slope of the line through the points (-10, 6) and (-5, 8) is 0.4

You need to work 84 hours per month at your second job to meet your monthly savings goal.

Fixed expenses = 2,034.24 x 30% = $610.72

Discretionary income = 2,034.24 - 610.72 = $1,423.52

Savings goal per month = $1,423.52 x 20% = $284.70

Net pay per hour = $9.50 - ($9.50 x 7.65%) - ($9.50 x 11.5%) - ($9.50 x 7.75%) = $7.33

Hours per month = $284.70 ÷ $7.33 = 84 hours.

To calculate, first find the number of your fixed expenses by multiplying your primary job income by 30%. This is $610.72. Then subtract your fixed expenses from your primary job income to find your discretionary income, which is $1,423.52. Multiply that by 20% to find the amount you want to save each month, which is $284.70.

Finally, divide that amount by your net pay per hour after taxes from your second job, which is $7.33, to find the number of hours you need to work, which is 84 hours.

The amount of caffeine in the bloodstream after different times decreases following an exponential decay pattern.

Caffeine is a natural chemical with stimulant effects.

Let's call the new half-life time for an individual with extended half-life as t. The function for the amount of caffeine (C) in the bloodstream after time t can be expressed as:

C(t) = 80 * (1/2)^(t/8)

Using this formula, we can determine the amount of caffeine in the bloodstream after different times:

1 hour:

C(1) = 80 * (1/2)^(1/8) = 80 * (1/2)^0.125 ≈ 79.28 mg

5 hours:

C(5) = 80 * (1/2)^(5/8) ≈ 64.51 mg

10 hours:

C(10) = 80 * (1/2)^(10/8) ≈ 51.37 mg

Answer:

No solution, because the slopes are the same and the y-intercepts are different.

Step-by-step explanation:

The two equations are:

y = 1/4x + 1 and y= 1/4x - 1

Since the left sides are equal we can equate the right sides:
1/4x + 1 = /4x - 1

1/4x cancels out of the equation and we get the absurdity:

1 = -1

This indicates no solution to the system of equations

Answer:
No solution, because the slopes are the same and the y-intercepts are different.

We can see that the slopes are the same (1/4) and the y-intercepts are different (1 and -1)

When the slope of the line is 3 the equation of the line using point slope formula is

D. у - 8 = 3 (x - 6)

Point slope formula is giving by (y - y₁) = m (x - x₁)

where

m = slope

x₂ and x₁ = points in x coordinates

y₂ and y₁ = points in y coordinates

For slope of 3, equation passing through point (5, 8)

(y - y₁) = m (x - x₁)

y - 8 = 3 (x - 6)

y - 8 = 3x - 18

y = 3x - 18 + 8
