#11: Looking at the rectangle below, find the area.

Latoya swims 7 kilometers per hour if there were no currents.

Latoya's speed without the current can be calculated by adding the speed she swam against the current (S-c) to the speed of the current (c). Since she swam the same distance at the same time in both cases, we know that (S-c) * t = S * t. Therefore, S = (S-c) + c. We know that the rate of the current is c = 2 Km/h and she swam 5 Km against the current, so (S-c) = 5 Km/t and S * t = 15 Km.

By substituting the values, we get S = (5 + 2) Km/t = 7 Km/t.

Complete question :

Latoya swam 5 kilometers against the current in the same amount of time it took her to swim 15 kilometers with the current. The rate of the current was 2 kilometers per hour. How fast would Latoya swim if there were no currents?

Answer:

Option B) 803.84in²

Step-by-step explanation:

We know the formula to find the area of a circle is listed as,

[tex]A = \pi r^{2}[/tex]

But over here the diameter is only given

that means we have to find the radius which is,

[tex]r = \frac{32}{2}[/tex]

[tex]r = 16in[/tex]

Now we can find the area of a circle which is,

[tex]A = 3.14X(16)^{2}[/tex]

[tex]A = 803.84in^{2}[/tex]

Hence , Option B) is the correct answer

If the value of a car is $21000 and it loses 8% of its value every year , then the approximate monthly decrease in value is $140   .

The value of the car is given as = $21000 ;

the percent decrease in the value of car is = 8% every year ;

So , in 1 year the value of car decreased is = [tex]0.08\times 21000[/tex]

= [tex]1680[/tex]  .

So , in 1 year value of car decreased by $1680 ;

to find the monthly decrease , we divide the value by 12 ;

the monthly decrease is = [tex]\frac{1680}{12}[/tex] = $140 .

Therefore , The Approximate monthly decrease in the value of car is $140 .

Trigonometry is the study of the correlations between triangle angles and side lengths.

Sine, cosine, tangent, cosecant, sec, and cotone are the six trigonometric functions.

Suppose the angle is such that

opposite/hypotenuse = sin

neighboring / hypotenuse = cos

tan = opposite or nearby

Tan equals sin and cos.

Cot = 1 + Tan

given the data,

Let ABC be the triangle.

The angles inside the triangle ABC are 45°, 45°, and 90°. The triangle ABC is a right-angled triangle.

Now, based on the illustration,

trigonometric relationships

tan θ = x / √2

Now , θ = 45°

The coordinates of K are (3, 1).

What is the coordinate point?

The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane. Recall that the coordinate plane has two axes at right angles to each other, called the x and y-axis. The coordinates of a given point represent how far along each axis the point is located.

Point K is 1/n of the way from J(4,5) to L(0,-7). To find the coordinates of K, we can use the concept of linear interpolation.

Given two points J(x1,y1) and L(x2,y2) and a value of t, such that 0<=t<=1, the coordinates of the point K(x,y) that is t of the way from J to L is given by:

x = (1-t)x1 + tx2

y = (1-t)y1 + ty2

In this case, we know that n=4 and t = 1/4.

So the x and y coordinates of K are:

x = (1-1/4)x1 + (1/4)x2 = (3/4)x1 + (1/4)x2 = (3/4)(4) + (1/4)(0) = 3

y = (1-1/4)y1 + (1/4)y2 = (3/4)y1 + (1/4)y2 = (3/4)(5) + (1/4)(-7) = 1

Hence, the coordinates of K are (3, 1).

The polynomial identities and proofs are mathematical statements that show that two algebraic expressions are equal. They can be used to simplify equations or to prove certain properties of polynomials.

For example, to prove x^2 + 2x + 1 = (x + 1)^2, you can factor the left side and expand the right side. This will show that x^2 + 2x + 1 = x^2 + 2x + 1 and thus the two polynomials are equal.

x^2 + 2x + 1

= (x + 1) (x + 1)

= x^2 + 2x + x + 1

= x^2 + 3x + 1

= (x + 1)^2

To prove that x^2 + 2x + 1 = (x + 1)^2, we first factor the left side x^2 + 2x + 1 and expand the right side (x + 1)^2. This will give us two equations: x^2 + 2x + 1 and x^2 + 3x + 1. From here, we can observe that both equations are identical, and thus the two polynomials are equal. This can be further verified by noting that the left side is the result of squaring x + 1, and the right side is the square of x + 1. Therefore, x^2 + 2x + 1 is equal to (x + 1)^2.

The angle-side connection theorem states that angle E in triangle DEF is equal to angle F.

Since a triangle has three sides and three vertices, it is a polygon. It is a fundamental geometric shape. Triangle ABC is the moniker given to a triangle that has vertices A, B, and C. When the three points are not collinear, a singular plane and triangle are found in Euclidean geometry. A triangle is a polygon if it has three sides and three corners. The points where the three sides meet are known as the triangle's corners.

given

The length of every triangle side is proportional to the size of the angles that are directly across from them, according to the angle-side relationship theorem.

Thus,

Angle F = (61 + 58)/180 (sum of triangle)

F = 61 degree angle

Since mE = 61 degrees, F and E are therefore congruent to one another.

It follows that the sides that are perpendicular to each angle will also be parallel to one another.
