construction crew needs to pave a road that is 206 miles long. The crew paves 9 miles of the road each day. The length, L (in miles), that is left to be paved after d days is given by the following function

The common chord has a length equal to 6 centimeters.

In this problem we find the case of two circles of different radii (r₁ = 5 cm, r₂ = 3 cm), whose distance between centres is equal to 4 centimeters. We are required to determine the length of the chord common to the two circles.

First, determine one angle of a triangle by law of cosine:

cos θ = [(5 in)² - (3 in)² - (4 in)²] / [- 2 · (3 in) · (4 in)]

θ ≈ 90°

Second, determine the length of the common chord:

x = 2 · (3 cm)

x = 6 cm

The length of the common chord is equal to 6 centimeters.

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,

The domain of the function f(x) = 10x + 8 will be all x values such that 0 ≤ x < 248.

The domain of a function is the set of all possible input values for which the function is defined. For the function f(x) = 10x + 8, the domain will be all real numbers greater than or equal to 0. This can be seen by examining the equation: if x = 0, then f(x) = 8. Therefore, the domain of the function will be all x values such that x ≥ 0. To calculate the upper bound for the domain, we can solve for x by subtracting 8 from both sides of the equation, resulting in 10x = -8. Dividing both sides by 10 gives us x = -0.8. Therefore, the domain of the function f(x) = 10x + 8 will be all x values such that 0 ≤ x < 248.

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

20 hours:

If two line segments are parallel to each other and the first line segment has endpoints at (2, 3) and (1,9) while the second line segment has endpoints at (5, 4) and (3,Y), the value of y is:

Two lines are parallel if and only if they have the same slope. So, to find the value of y, we need to find the slope of the first line segment and use it to find the equation of the second line segment.

The slope of the first line segment can be found using the formula:

Since the two lines are parallel, they have the same slope, so we can use the slope to find the equation of the second line segment.

Expanding the equation and solving for y, we get:

Now that we have the equation of the second line segment, we can use the x-coordinate of one of its endpoints (3) to find the corresponding y-coordinate.

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.

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

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.

The volume of a solid rotated around the y-axis can be calculated using the "Disk Method"

The disk method is predominantly used when we rotate any particular curve around the x or y-axis.

Suppose a function x = f(y), which is rotated about the y-axis.

The volume of the solid formed by revolving the region bounded by the curve x = f(y) and the y-axis between y = c and y = d about the y-axis is given by

V = π ∫dc [tex][f(y)]^{2}[/tex]dy.

The cross-section perpendicular to the axis of revolution has the form of a disk of radius R = f(y)

Thus, the volume of a solid rotated about the y-axis can be calculated by V = π∫dc[tex][f(y)]^{2}[/tex]dy. Option (A)

The graph of the exponential function:

f(x) = 2*(3)^x

Is the first one.

We want to find the graph of the exponential function:

f(x) = 2*(3)^x

To identify it, you can evaluate the function in some different values of x.

if x = 0

f(0) = 2*(3)^0 = 2

if x = 1

f(1) = 2*3^1 = 6

if x = 2

f(2) = 2*(3)^2 = 18

So we have the 3 points:

(0, 2), (1, 6), (2, 18)

The only graph that passes through these points is the first one, so that is the correct option.
