How many inches in 2 meters?

The number of miles he can travel on 44.2 gallons of gas would be = 1697.28 miles

The table shows that there is direct proportional relationship between the number of miles traveled and the number of gallons used by Parker. That is increase in the number of mile = increase in the number of gallons.

If 34 gallons = 1305.6 miles

44.2 gallons = X miles

Make X miles the subject of formula;

X miles = 44.2 × 1305.6/34

= 57707.52/34

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

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:

16

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.

So, the value of y is 16.

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.

Answer:

4 is there answer I think

Step-by-step explanation:

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.

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

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

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

The largest interval I over which the general solution is defined is (-∞, ∞).

A differential equation is a mathematical equation that relates an unknown function to its derivatives. It expresses the relationship between an dependent variable (the unknown function) and one or more independent variables. Differential equations are used to model physical, biological, and economical systems, among others.

A differential equation can be thought of as an equation that describes how a function changes over time. For example, the velocity of an object is the derivative of its position with respect to time. If the position of the object is modeled by a function, then its velocity can be described by a differential equation.

ODEs deal with functions of a single variable and their derivatives, while PDEs deal with functions of multiple variables and their partial derivatives.

The given differential equation is a first-order linear ordinary differential equation with constant coefficients:

dy/dx + y = e⁷ˣ

This equation can be solved using the method of integrating factors. The integrating factor is given by e^∫1 dx = e^x. Multiplying both sides of the equation by the integrating factor, we get:

eˣ(dy/dx) + eˣ y = e⁸ˣ

Integrating both sides, we get:

eˣ y = e⁸ˣ - eˣ + C, where C is an arbitrary constant of integration.

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 nth octagonal number is given by the formula: n(3n-2)

So, the sum of the 3rd triangular number, 4th square number, 5th pentagonal number, 6th hexagonal number, 7th heptagonal number and 8th octagonal number can be calculated as follows:

Triangular number: 3 * (3 + 1) / 2 = 6

Square number: 4² = 16

Pentagonal number: 5 * (3 * 5 - 1) / 2 = 35

Hexagonal number: 6 * (2 * 6 - 1) = 91

Heptagonal number: 7 * (5 * 7 - 3) / 2 = 98

Octagonal number: 8 * (3 * 8 - 2) = 128

The sum of these numbers is: 6 + 16 + 35 + 91 + 98 + 128 = 384.

So, the sum of the 3rd triangular, 4th square, 5th pentagonal, 6th hexagonal, 7th heptagonal, and 8th octagonal numbers is 384.
