They will lift the same weight (which is 26 kilograms) after one set.

Mason starts at 19kg bar and adds 7kg after each set, so after x sets, he will be lifting:

M(x) = 19 + 7*x

And Jack starts at 18kg, and after each set adds 8kg, then in this case the linear equation is:

J(x) = 18 + 8*x

They will lift the same weight when:

M(x) = J(x)

19 + 7*x =  18 + 8*x

19 - 18 = 8x - 7x

1 = x

So they will be lifting the same weight after one set, and that is:

J(1) = 18 + 8*1 = 26

26 kilograms.

Answer: 2 3/4.

Step-by-step explanation: To multiply the mixed numbers, we need to first make them into improper fractions. To make 2 1/5 into an improper fraction, we multiply the whole number 2 by the denominator, 5, and add that to the numerator 1, giving us 11/5. We do the same for 1 1/4, giving us 5/4. 5/4 x 11/5 equals 55/20. 55/20 simplifies to 2 3/4.

I and II only are solutions to the differential equation y′′ − 5y′ + 6y = 0.

Let's assume y = e^2t is the solution of the given differential equation y′′ − 5y′ + 6y = 0.

Now, put y = e^2t in the given differential equation y′′ − 5y′ + 6y = 0

(e^2t)'' - 5(e^2t)' + 6(e^2t) = 0

Now differentiate it; we get

4e^2t - 10e^2t + 6e^2t = 0

0 = 0

So, here we can see that y = e^2t satisfies the equation y′′ − 5y′ + 6y = 0.

Therefore y = e^2t is the solution of the given differential equation.

Now let's assume y = 3e^3t is the solution of the given differential equation y′′ − 5y′ + 6y = 0.

Put y = 3e^3t in the given differential equation y′′ − 5y′ + 6y = 0

(3e^3t)'' - 5(3e^3t)' + 6(3e^3t) = 0

Now differentiate it; we get

27e^3t - 45e^3t + 18e^3t = 0

0 = 0

So, here we can see that y = 3e^3t satisfies the equation y′′ − 5y′ + 6y = 0.

Therefore y = 3e^3t is the solution of the given differential equation.

Similarly, let's assume y = 3sin(2t) is the solution of the given differential equation y′′ − 5y′ + 6y = 0.

Put y = 3sin(2t) in the given differential equation y′′ − 5y′ + 6y = 0

(3sin(2t)'' - 5(3sin(2t))' + 6(3sin(2t)) = 0

Now differentiate it; we get

-24cos(2t) + 30cos(2t) + 18sin(2t) = 0

-24cos(2t) + 30cos(2t) + 18sin(2t) ≠ 0

So, here we can see that y = 3sin(2t) does not satisfies the equation y′′ − 5y′ + 6y = 0.

Therefore y = 3sin(2t) is not the solution of the given differential equation.

Hence, I and II only are solutions to the differential equation y′′−5y′+6y=0.

--The given question is incorrect; the correct question is

"Of the following, which are solutions to the differential equation y′′−5y′+6y=0?

The dimensions of the outdoor enclosure with the most area is 250 feet and 125 feet.

One side of the store is 270 feet long

There are 500 feet of fencing available for the other three sides of the enclosure.

The Perimeter of rectangular outdoor storage = 2x + y

2x + y = 500

To maximize the area

y = 500 - 2x...............(1)

Area of rectangle;

A = xy

Now putting the value of y

A = x(500 - 2x)

Solve

A = 500x - 2x^2...................(2)

To finding the value of x differentiating on both side with respect to x.

dA/dx = 500 - 4x...................(3)

Equating dA/dx = 0

500 - 4x = 0

Subtract 4x on both side, we get

4x = 500

Divide by 4 on both side, we get

x = 125

Now putting the value of x in equation 1

y = 500 - 2(125)

y = 500 - 250

y = 250

Differentiating equation 3 again with respect to x

d^2A/dx^2 = -4 < 0 (Maximum)

I = P x R x T/365, where I is the interest, P is the principal, R is the rate, and T is the duration, can be used to determine the interest rate using exact days.

I = 61625 - 60000 = 625, P = 60000, R =?, and T = 150 are the numbers used in this calculation. The formula for 625 reads as follows: 625 = 60000 x R x 150/365. By multiplying both sides by 365/150, we may find R. As a result, R = 625 x 365/90000 = 4.17%.

I = P x R x T/360, where I is the interest, P is the principal, and R is the rate of return, can be used to get the interest rate using regular days.T stands for time, and R represents the rate. I = 61625 - 60000 = 625, P = 60000, R =?, and T = 150 are the numbers used in this calculation. The formula for 625 reads as follows:

625 = 60000 x R x 150/360. By dividing both sides by 360/150, we may find R. As a result, R = 625 x 360/90000 = 4.21%.

I = P x R x T/365, which means that R = I x 365/P x T = 625 x 365/60000 x 150 = 4.17%. Exact days

I = P x R x T/360 on typical days, which means that R = I x 360/P x T is 625 x 360/60000 x 150, or 4.21%.

The number of distinct initial possible pairings for a single-elimination ping-pong tournament with n players that result in distinct tournament brackets is 2^(log2(n) - 1).

What is logarithm ?

The logarithm is the inverse function to exponentiation. That means the logarithm of a number x to the base b is the exponent to which b must be raised, to produce x.

In a single-elimination ping-pong tournament, each player plays one match in each round until a champion is determined. For n players, there are log2(n) rounds in the tournament, and in each round half the players are eliminated.

For n = 2, there is only 1 player left after the first round, so there is only 1 distinct pairing and 1 distinct tournament bracket.

For n = 4, there are 2 players left after the first round, and they play in the final. There are 2 possible pairings for the first round, which result in 2 distinct tournament brackets.

For n = 8, there are 4 players left after the first round, and there are 4 possible pairings for the first round. These pairings result in 4 distinct tournament brackets.

So the number of distinct initial possible pairings for a single-elimination ping-pong tournament with n players that result in distinct tournament brackets is 2^(log2(n) - 1).

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the centre.

The centre angle of one radian (s = r) subtends an arc length of one radius. One radian has the same value for all circles because they are all alike. The central angle of a circle is measured by its arc, which is 360 degrees, and its radian measure, which is 2 radians.

The tangent line to the curve y = ln(x) - 10 at the point (1, -9) is parametrized by x = t and y = t - 10

To find the tangent line to the curve y = ln(x) - 10 at the point (1, -9), we need to find a parametrization of the line. We can do this by finding the slope of the tangent line and the point at which the tangent line intersects the y-axis.

First, we find the slope of the tangent line by taking the derivative of the function y = ln(x) - 10 at x = 1:

dy/dx = d/dx ln(x) = 1/x

So, the slope of the tangent line at (1, -9) is m = 1/1 = 1.

Next, we find the y-intercept of the tangent line. This can be found by using the point-slope form of a line:

y - y1 = m(x - x1)

Substituting in the values for m, x1, and y1, we get:

y - (-9) = 1(x - 1)

Simplifying, we find:

y + 9 = x - 1

y = x - 10

So, the y-intercept of the tangent line is -10.

Putting everything together, we find that the parametrization of the tangent line to the curve y = ln(x) - 10 at the point (1, -9) is given by:

x = t

y = x - 10 = t - 10

So, the tangent line to the curve y = ln(x) - 10 at the point (1, -9) is parametrized by x = t and y = t - 10.

Answer:Let x be the cost of a hard-cover book and y be the cost of a paperback book.

We know that Steve spent 2 hard-cover books and 3 paperback books. So we can write the equation as:

2x + 3y = 50 - 15.5

2x + 3y = 34.5

We also know that he was planning to buy 3 hard-cover books and 4 paperbacks, so we can write another equation as:

3x + 4y = 50

Now we have a system of two equations with two unknowns:

2x + 3y = 34.5

3x + 4y = 50

We can use the first equation to eliminate one variable by multiplying both sides by 2 and then subtracting 3y:

4x + 6y = 69

3x + 4y = 50

x = 19.5

Now we can substitute this value of x into the second equation and find the value of y:

3(19.5) + 4y = 50

58.5 + 4y = 50

4y = -8.5

y = -2.125

Therefore, the cost of a hard-cover book is $19.5 and the cost of a paperback book is $-2.125.

The expansion for cos(x+y) is cosx*cosy - sinx*siny. We have sin x and cos y, now we need cosx and siny.

Angle x is in QIII and has a sin ratio of -5/6. Since the hypotenuse will never be negative and sin is opposite over hypotenuse, the side across from the reference angle, aka the height of the triangle, is -5 and the hypotenuse is 6. Using Pythagorean's Theorem we can find the third side:

[tex]6^2=(-5)^2+x^2[/tex] and

[tex]36=25+x^2[/tex] and

[tex]36-25=x^2[/tex] so

x = √11.

We do the same for the other angle y. We have the cos of angle y is 1/2 and since the cos ratio is adjacent over hypotenuse, the side next to the reference angle is 1 and the hypotenuse is 2 and we will find the third side using Pythagorean's Theorem:

[tex]2^2=1^2+y^2[/tex] and

[tex]4=1+y^2[/tex] and

[tex]3=y^2[/tex] so

y = √3.

We already know sinx = -5/6, now we know that cosx = -√11/6.

We already know cosy = 1/2, now we know that siny = -√3/2.

The x- intercepts in parabola is (1,0) and (5,0).

A parabola is a type of symmetrical, U-shaped curve that is a graph of a quadratic function. It is defined by the equation y = ax² + bx + c, where a, b, and c are constants. The shape of the parabola is determined by the value of the coefficient "a". If a > 0, the parabola opens upwards, and if a < 0, the parabola opens downwards.

Parabolas are used in many areas of mathematics and science, including physics, engineering, and economics. For example, they are used to model the trajectory of objects under the influence of gravity, to describe the motion of objects in space, and to analyze the behavior of systems that exhibit parabolic patterns.

The vertex of a parabola is the point that represents the highest or lowest point on the curve, and the axis of symmetry is a line that separates the curve into two congruent halves.

The x-intercepts of a parabola can be found by setting the y-value to 0 and solving for x. In this case, the y-coordinate of the x-intercepts will be 0, so we have:

y = 0

To find the x-intercepts, we can use the information given in the coordinates of the parabola: (1,0), (5,0), and (0,6).

From the coordinates (1,0) and (5,0), we can see that the x-intercepts are at 1 and 5.

From the coordinate (0,6), we can see that the y-intercept is at (0,6).
