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.

I am pretty sure the answer would be (2,3)

Answer:

Step-by-step explanation:

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.

Now we can fill in the expansion for cos(x+y):

[tex](-\frac{\sqrt{11} }{6})(\frac{1}{2})-(-\frac{5}{6})(-\frac{\sqrt{3} }{2})[/tex] Multiplying straight across the top and bottom we get

[tex]-\frac{\sqrt{11} }{12}-\frac{5\sqrt{3} }{12}[/tex] which simplifies to

[tex]\frac{-\sqrt{11}-5\sqrt{3} }{12}[/tex]

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).

m∠1 = 49°, m∠2 = 41°, m∠3 = 41°, m∠ADC = 90°, AB = 6.9, BD = 10, and CE = 5.

Considering the triangle AEB, angles A and B are base angles of a the isosceles triangle AEB so;

2(m∠ABE) + 98 = 180° {sum of interior angles of a triangle}

m∠ABE = (180 - 98)/2

m∠ABE = 41°

m∠1 = 90° - 41° {complementary angles of a rectangle}

m∠1 = 49°

angles m∠2 and m∠BAC are alternate angles and are equal so;

m∠2 = 41°

m∠ADC is one of the four interior angles of a rectangle so m∠ADC = 90°

Considering the right triangle ∆ABD and the tangent of angle B = 41°, we can solve for the length of AB as follows:

tan 41° = 6/AB {opposite/adjacent}

AB = 6/tan41° {cross multiplication}

AB = 6.9022.

m∠3 and m∠ABD are alternate angles so;

m∠3 = 41°

The required Angle in radian in simplest form is 2π.

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.

Radius = 4 unit, arc = 8π

We know that

angle = arc/radius

angle = 8π/4

angle = 2π radian.

Thus, required angle in radian is 2π.

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.

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).

So, the x-intercepts of the parabola are (1,0) and (5,0).
