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?

On the graph above, the input when f(x) = -5 is equal to -2.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

Next, we would determine the linear equation representing the line and passes through the points (-1, -2) and (1, 4) by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - (-2) = (4 - (-2))/(1 - (-1))(x - (-1))

y + 2 = 6/2(x + 1)

y = 3(x + 1) - 2

y = 3x + 3 - 2

y = 3x + 1

When y = -5, the input value (x) can be calculated as follows;

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).

Annabelle has collected approximately 213.7 grams of the trace element.

What is the volume of a cylinder?

The volume of a cylinder can be calculated using the formula V=πr2(h). When determining the volume of a cylinder, you are simply finding the area of the circular base shape and then multiplying this by the height.

The container has the shape of a right cylinder, so the volume of the cylinder can be found by using the formula for the volume of a cylinder: V = πr^2 * h

Where r = radius , h = height, and π = 3.14

So, the volume of the container is:

V = 3.14 * 8.6^2 * 16.5 = 3.14 * 73.96 * 16.5 = 2959.18 cm^3

Now we can use this volume and the proportion of the trace element given in the problem to find the approximate amount of trace element Annabelle has collected:

0.072 g/cm^3 * 2959.18 cm^3 = 213.7 grams

Hence, Annabelle has collected approximately 213.7 grams of the trace element, rounded to the nearest tenth.

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.

The angle-side connection theorem states that angle E in triangle DEF is equal to angle F, which also implies that the sides that are opposite one other are congruent.

The correct statement is D. Yoni CANNOT dunk the basketball because the discriminant of 0 = -16t² + 10t - 2.5 is negative.

The discriminant of a quadratic equation is the value that is inside the square root sign of the equation,

Given that

h(t) = -16t² + 10t

Height = 2.5

We have

-16t² + 10t = 2.5

This gives

0 = -16t² + 10t - 2.5

In this case, the discriminant of the equation 0 = -16t² + 10t - 2.5 is negative, which means that there are no real roots.
