Step-by-step explanation:
latoya swam kilometers against the current in the same amount of time it took her to swim kilometers with the current. the rate of the current was kilometers per hour. how fast would latoya swim if there were no current?
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.

point K is 1/n of the way from J(4,5) to L(0,-7). what are the coordinates of K if n=4
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).

3. 05 polynomial identities and proofs
I have no idea how to do this assignment, since I’m doing home school now I don’t have anyone to help
SOMEONE PLEASE HELP!!
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.

A water sample shows 0.072 grams of some trace element for every cubic centimeter of water. Annabelle uses a container in the shape of a right cylinder with a radius of 8.6 cm and a height of 16.5 cm to collect a second sample, filling the container all the way. Assuming the sample contains the same proportion of the trace element, approximately how much trace element has Annabelle collected? Round your answer to the nearest tenth.
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

When Yoni jumps as high as he can, the function h (t) = -16t2 + 10t models his height above the ground, in feet, where t is the number of seconds since he left the ground. Yoni needs to jump 2.5 feet in the air to be able to dunk a basketball. Which statement BEST explains why Yoni can or cannot dunk the basketball?
A Yoni CAN dunk the basketball because the discriminant of 0 = -16t² + 10t-2.5 is positive.
B Yoni CAN dunk the basketball because the discriminant of 0= -16t² + 10t - 2.5 is negative.
C Yoni CANNOT dunk the basketball because the discriminant of 0= -16t² + 10t - 2.5 is positive.
D Yoni CANNOT dunk the basketball because the discriminant of 0 = -16t2 + 10t-2.5 is negative.
The correct statement is D. Yoni CANNOT dunk the basketball because the discriminant of 0 = -16t² + 10t - 2.5 is negative.
How to determine the correct statementThe discriminant of a quadratic equation is the value that is inside the square root sign of the equation,
in this case: b²-4ac.
If the discriminant is positive, it means that the equation has two distinct real roots.If the discriminant is zero, it means that the equation has one real root.If the discriminant is negative, it means that the equation has no real roots.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.
This means that Yoni will not reach the height of 2.5 feet because the equation has no real solutions, so he cannot dunk the basketball
