Tarzan is swimming east at 2.4 m/s across a river that is 1660 meters wide and
flows north at 5.2 m/s
What is tarzan’s final rate of swimming?
Answers
Tarzan’s final rate of swimming is 4.83 minutes.
What is velocity?Velocity is the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference.
Now it is given that,
Tarzan is swimming east at Velocity, Vt = 2.4 m/s
River's Velocity flowing north, Vr = 5.2 m/s
Width of river = 1660 meters
So, resultant speed of Tarzan, V = √(Vt² + Vr²)
⇒ V = √(2.4² + 5.2²)
⇒ V = √(5.76 + 27.04²)
⇒ V = √32.8 m/s
⇒ V = 5.73 m/s
Thus, rate of swimming = Width / V
⇒ rate of swimming = 1660 / 5.73 s
⇒ rate of swimming = 289.70 s
or, rate of swimming = 4.83 minutes
Thus, Tarzan’s final rate of swimming is 4.83 minutes.

Answer:
x = ± 2
Step-by-step explanation:
To find the zeros set the polynomial equal to zero, that is
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
Thus x = - 2 or x = 2

What does a correlation coefficient mean?
A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another. In positively correlated variables, the value increases or decreases in tandem.
What is a perfect correlation?
A relationship between two variables, x, and y, in which the change in the value of one variable is exactly proportional to the change in the value of the other. That is, knowing the value of one variable exactly predicts the value of the other variable (i.e., rxy = 1.0).

A circle with radius 9 has a sector with a central angle of 120°.
What is the area of the sector?
Answers
120º is 1/3 of a complete revolution of 360º. So the area of this sector should be 1/3 the area of the complete circle.
A circle with radius 9 has area 9^2 π = 81π.
So the sector has area 81π/3.
Put another way: The area A of a circular sector and its central angle θ (in degrees) occur in the same ratio as the area of the entire circle with radius r according to
A / θ º = (π r ^2) / 360º
==> A = π/360 θ r ^2
In this case, r = 9 and θ = 120º, so
A = π/360 * 120 * 81 = 81π/3

In step 1, he did not put the function in standard form correctly.
In step 2, he should have also factored –7 from the constant term, 17.
In step 3, he did not subtract –7(9) to keep the function equivalent.
In step 4, he did not write the perfect square trinomial correctly as a binomial squared.

In step 3, he did not subtract –7(9) to keep the function equivalent. Therefore, the correct option is option C among all the given options.
What is mathematical function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a predictor variables (the dependent variable).
In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences. German mathematician Paul Dirichlet initially offered the standard concept of function in 1837. When Nick checked his work it did not match the standard form function. In step 3, he did not subtract –7(9) to keep the function equivalent.
Therefore, the correct option is option C.

Your question is incomplete but most probably your full question was,
Nick wrote the function p(x) = 17 + 42x – 7x2 in vertex form. His work is below.
p(x) = –7x2 + 42x + 17
p(x) = –7(x2 – 6x) + 17
= 9;
p(x) = –7(x2 – 6x + 9) + 17
p(x) = –7(x – 3)2 + 17
When Nick checked his work it did not match the standard form function. Analyze Nick’s work. What was his mistake?
In step 1, he did not put the function in standard form correctly.
In step 2, he should have also factored –7 from the constant term, 17.
In step 3, he did not subtract –7(9) to keep the function equivalent.
In step 4, he did not write the perfect square trinomial correctly as a binomial squared.
Nick made mistakes in converting to standard form, factoring constants correctly, maintaining equivalence, and writing perfect square trinomials. Correcting these steps will yield an accurate transformation of the equation.
Let's break down the steps Nick likely took and identify where he went wrong in putting the quadratic equation into its standard form.
Step 1: Initially converting the equation to standard form. For the equation x² + 4x + 21 = 0, the equation was already in standard form, so no changes were necessary here. It’s possible that Nick incorrectly adjusted coefficients, which led to errors.Step 2: Factoring out terms. If Nick had an equation like -7x² + 17 = 0, he should have factored out -7 from both the x² term and the constant term, resulting in -7(x² - 17/7) = 0. Missing this step would lead to misrepresentation of the equation.Step 3: Ensuring equivalence. Nick should have subtracted -7(9) correctly to maintain the function's equivalence throughout the transformation.Step 4: Writing the perfect square trinomial correctly. To complete the square, for example, (x + 2)² should be correctly represented as a binomial squared. Not doing so indicates an error in the transformation process.In summary, Nick’s mistakes include incorrect standard form conversion, improper factoring of constant terms, failing to maintain equivalence, and incorrect representation of perfect square trinomials.
