Step-by-step explanation:

The total number of people combined in rooms A, B, and C is 21 + x.

What is combination?

In mathematics and combinatorial theory, a combination refers to the selection of items from a larger set without considering their order.

Let's solve this step by step using the given information.

Room A contains 7 people.

Room B contains the number of people in A plus half the number of people in C. Since we don't know the number of people in C yet, let's represent it with the variable "x". Therefore, the number of people in Room B is 7 + (1/2)x.

Room C contains the same number of people as Room A and Room B combined. So, the number of people in Room C is (7 + (1/2)x) + (7 + (1/2)x).

Room C contains the same number of people as Room A and Room B combined. So, the number of people in Room C is (7 + (1/2)x) + (7 + (1/2)x).

To find the total number of people in rooms A, B, and C combined, we add the number of people in each room:

Total = Room A + Room B + Room C
Total = 7 + (7 + (1/2)x) + (7 + (1/2)x)

Simplifying the equation:

Total = 7 + 7 + 7 + (1/2)x + (1/2)x
Total = 21 + x

Therefore, the total number of people combined in rooms A, B, and C is 21 + x.

Step-by-step explanation:

If it takes 20 h for 5 gallons to be filled, it takes 4 h for 1 gallon to be filled. This is the ratio. You multiply 4 h by 12 to get 48 h, so you multiply 1 gallon by 12 as well. This is 12 gallons.

Answer:

Step-by-step explanation:

Given parametric equations are,

x = t(t² − 147

)y = 2(t² − 147)

a) We are to find out the point on the curve where the tangent is horizontal.

If we differentiate x and y with respect to t, we get,

x = t(t² − 147)

dx/dt = 3t² − 147

y = 2(t² − 147)

dy/dt = 4t

Now, for the tangent to be horizontal,

dy/dt = 0

Therefore, 4t = 0 or t = 0

Therefore, when t = 0, the tangent is horizontal.

The point on the curve is

(x, y) = (0, −294).

b) We are to determine the points t1 and t2

where the tangent is vertical and t1 < t2.

If we differentiate x and y with respect to t, we get,

x = t(t² − 147)

dx/dt = 3t² − 147

y = 2(t² − 147)

dy/dt = 4t

Now, for the tangent to be vertical,

dx/dt = 0

Therefore, 3t² − 147 = 0 or t² = 49 or t = ±7.

Now,

d²y/dx² = (d²y/dt²) / (d²x/dt²)

= 2 / (6t)

= 1 / (3t)

So, d²y/dx² is defined at t = 7 and t = −7.

Since x = t(t² − 147), x is an odd function of t and so the curve is symmetric about the origin.

Therefore, the points where the tangent is vertical are

(x, y) = (7²(7² − 147), 2(7² − 147)) and (x, y) = (−7²(−7² − 147), 2(−7² − 147)).

Simplifying, we get,t1 = −7, t2 = 7 and the required points are (x, y) = (686, −980) and (x, y) = (−686, −980).

There is only one point where the tangent is vertical and t1 = t2 = 0. The point is (0, -294).

Given, parametric equations of the curve are

x = t(t² - 147)y = 2(t² - 147)

The derivative of x with respect to t will give the slope of the tangent to the curve with respect to x.

Now, using the chain rule, the derivative of x with respect to t will bedx/dt = (d/dt) [t(t² - 147)]

Let’s expand and simplify

d/dt (t³ - 147t) = 3t² - 147

This is the slope of the tangent to the curve with respect to x.

For horizontal tangent, the slope must be zero. So we have to solve

3t² - 147 = 0  

⇒  3(t² - 49) = 0

⇒ t² - 49 = 0

⇒ t = ±7

The value of t for horizontal tangent is 7 and -7.

So the point on the curve where the tangent is horizontal can be found by putting t = 7 or t = -7 in the given equation of y.

Therefore the point will be(-686, -588) and (686, -588)

Now, using the chain rule, the derivative of y with respect to t will be dy/dt = (d/dt) [2(t² - 147)]

Let's expand and simplify

d/dt [2t² - 294] = 4t

For vertical tangent, the derivative of y with respect to t must be undefined. dy/dt is undefined at t = 0.

Thus, t1 = 0Putting t1 = 0 in the given equation of x, we can get the point on the curve where the tangent is vertical. Therefore the point will be (0, -294)

Now, to get the second value of t, let’s first differentiate the equation of x with respect to t again to obtain

d²x/dt² = (d/dt) [3t² - 147]d²x/dt²

= 6t

For vertical tangent, the slope must be undefined, thusd²x/dt² = 0

Therefore,6t = 0  

⇒  t = 0

Thus, we can conclude that there is only one point where the tangent is vertical and t1 = t2 = 0. The point is (0, -294).

The width of Cade's picture is 7.09cm. The perimeter of Cade's picture is 101.58 inchs.

What is a rectangular object?

A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can also be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal (360°/4 = 90°). A square is a rectangle with four equally long sides.

Given that Jens's picture is 36 centimeters long and 24 centimeters wide.

The area of a rectangular object is the product of length and width.

The area of Jens's picture is 36 × 24 cm² = 864 cm².

1 inches = 2.54 cm

The length of Cade's picture is 48 inches = 48× 24 cm = 121.92 cm

Assume that the width of Cade's picture is x.

The area of Cade's picture is 121.92x cm².

Given that the area of Cade's picture is the same as that of Jens's picture.

According to the question,

121.92x = 864

Divide both sides by 121.92:

x = 7.086

x = 7.09

The perimeter of a rectangular object is 2(l + w)

The perimeter of Cade's picture is 2(121.92 + 7.09) = 258.02 cm

Now convert it cm to inches:

=  258.02/2.54 inch

= 101.58 inchs

Answer:

It is important because they are the basics of algebra. Almost every algebraic problem you will ever solve is based on these fundamental properties. In equations, we almost never know every part of it so we will need variables to substitute the unknown amount in an equation. Variables are used for basically every equation/problem in algebra. Inequalities are not as important as variables but are still really important. Inequalities are basically comparing numbers. And in algebra when they add variables into an inequality, the inequality will help lower the number of possible values of said variable. And exponents are just a basic operation in algebra. Just like learning addition and subtraction. It is like a quicker and less complicated way of multiplying numbers.

The length of f to the nearest 10th of an inch is 1.8 inches.

Law of sines is defined as that ratio of the length of the sides of a triangle to the sine of the angle opposite to the these sides are equal.

That is, if a, b and c are sides opposite to the angles A, B and C respectively, then,

a / sin A = b / sin B = c / sin C

Given a triangle DEF.

The angles are given as, ∠F = 8° and ∠D = 34°.

We know,

Sum of the interior angles of a triangle = 180°

∠E = 180 - (8 + 34) = 138°

Using the law of sines,

f / sin F = e / sin E

f = (e / sin E) sin F

Substituting,

f = (8.7 / sin 138) sin 8

 = 13.0019 × 0.1392

 = 1.809

 ≈ 1.8

Hence the length of f to the nearest 10th of an inch is 1.8 inches.

Step-by-step explanation:

6m-2m =4m

Hence 4m+12

We are given that a carpenter is building a rectangular room with a fixed perimeter of 100 m. the dimensions of the largest room that can be built are 25m x 25m and its area is 625 m². Option (a) 25m x 25m, 625m² is correct.

Let's suppose the length of the rectangular room is "l" and the width is "w".Then, the perimeter of the rectangular room will be:P = 2(l + w). So, 100 = 2(l + w)Or, l + w = 50. We need to maximize the area of the rectangular room, which is given as A = lw. Now, we have two variables in this equation and we also have an equation for the perimeter.  For that, let's solve for one variable in terms of the other. We can solve for w as:w = 50 - l. Now, substitute this value of w in the equation for area: A = l(50 - l)

Simplifying, A = 50l - l²The area of the rectangular room is given by the quadratic equation: A = -l² + 50l. Here, a = -1 and b = 50. Substituting these values, we get: x = -50/(2 × -1) => x = 25This gives us the length of the rectangular room as 25 m. Substituting this value in the equation we derived for w:w = 50 - l = 50 - 25 = 25This gives us the width of the rectangular room as 25 m.
