PLEAZE HELPP 50 POINTS If the function f(x) =-3x3 +7x represents the movement of a whale in meters what is the average rate of change of the whale for x=1 and X=3 seconds label your answer
Answers
Answer:
The average rate of change of a function over an interval is found by taking the difference between the function's values at the endpoints of the interval and dividing by the length of the interval. In this case, we have:
f(1) = -3(1)^3 + 7(1) = -3 + 7 = 4
f(3) = -3(3)^3 + 7(3) = -27 + 21 = -6
The average rate of change over the interval from x=1 to x=3 is therefore (-6 - 4) / (3 - 1) = -10 / 2 = -5.
To label your answer, you could write something like: "The average rate of change of the whale's movement over the interval from x=1 to x=3 seconds is -5 meters/second."

The toe of which the triangle is , is called an isosceles triangle and a right angled triangle.
What is a triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. There are different types of triangle , some of them are ;
Scalene triangle, isosceles triangle , equilateral triangle e.tc.
To know the type of triangle it is, we need to find the length of each sides.
let A = (2,1)
B = (4,7)
C = ( 6,3)
AB = √ (4-2)²+ (7-1)²
AB = √ 2²+ 6²
AB = √2+36
AB = √40
= 2√10
BC = √ (6-4)²+( 3-7)²
BC = √ 2²+4²
BC = √4+16
BC = √20
= 2√5
AC = √ (6-2)²+(3-1)²
AC = √4²+2²
AC =√ 16+2
AC = √20
= 2√5
therefore since AB² = BC² + AC ² ,the triangle is a right angled triangle
And also since two sides of the triangle are equal it is an isosceles triangle.

Answer:
y = 3x + 6
Step-by-step explanation:
Since the line is parallel, it has the same slope -- 3
y = 3x + b, sub point (1, 9)
9 = 3(1) + b
9 = 3 + b
b = 9 - 3
b = 6
y = 3x + b -- y = 3x + 6
The slope remains the same as it’s parallel. Then replace the x and y with the coordinates (1,9) —> 9=3(1)+b and solve for b. B will equal to 6 and you just put it in y=Mx+b format.

Answers
Given:
\(x^2-5x-24=0\)First, let us keep the x terms on the left side and move the constant to the right side of the equation through adding 24 on both sides.
\(x^2-5x-24+24=0+24\)\(x^2-5x=24\)Next, we will take the half of the x term, 5x, and square it.
\((\frac{5}{2})^2=\frac{25}{4}\)And then, we will add this to both sides of the equation.
\(x^2-5x+\frac{25}{4}=24+\frac{25}{4}\)Then, we will rewrite the left side of the equation as a perfect square
\((x-\frac{5}{2})^2=\frac{121}{4}\)Take the square root of both sides
\(\sqrt[]{(x-\frac{5}{2})^2}=\sqrt[]{\frac{121}{4}}\)\(x-\frac{5}{2}=\pm\frac{11}{2}\)Solve for x (1)
\(x=\frac{5}{2}+\frac{11}{2}\)\(x=\frac{16}{2}\)\(x=8\)Solve for x (2)
\(x=\frac{5}{2}-\frac{11}{2}\)\(x=\frac{-6}{2}\)\(x=-3\)Now, we know that the values of x are -3 and 8, therefore, the answer would be C. x=-3 and x=8.

Answer:
A. The total number of three-card hands (permutations) that can be made with two aces is 576
B. The actual number of two-ace hands (combinations) you can get from a deck of 52 cards is 288
C. The probability of drawing a three-card hand that includes two aces from a deck of 52 cards is 0.0130
Step-by-step explanation:
A. In order to calculate the total number of three-card hands (permutations) that can be made with two aces we would have to make the following calculation:
total number of three-card hands (permutations) that can be made with two aces=4*3*52
total number of three-card hands (permutations) that can be made with two aces=576.
B. In order to calculate the actual number of two-ace hands (combinations) you can get from a deck of 52 cards we would have to make the following calculation:
actual number of two-ace hands (combinations) you can get from a deck of 52 cards=4C2*48
4C2=4!/2!2!
C2=6
Therefore, actual number of two-ace hands (combinations) you can get from a deck of 52 cards=6*48=288

(b) (5) The probability that the player will $1000 a week for life;
Answers
The probability of winning $1000 a day for life is approximately 5.245 x 10^-11 and the probability of winning $1000 a week for life is approximately 1.07 x 10^-8. The probability of winning the jackpot ($1000 a day for life) is 1/(60^5 * 4), while the probability of winning $1000 a week for life is 1/(60^5).
In the Florida Lottery Cash4Life game, a player must select five numbers from 1 to 60 and then one Cash Ball number from 1 to 4. The jackpot prize is $1000 a day for life if all five numbers and the Cash Ball match the winning numbers drawn on Monday nights. If just all five numbers match the winning numbers, the player will win $1000 a week for life.
To determine the probability of winning $1000 a day for life, we can use the formula for the probability of independent events: P(A and B) = P(A) x P(B)
(a) To win the jackpot of $1000 a day for life, the player needs to match all five numbers and the Cash Ball. There are 60 options for each of the five numbers and 4 options for the Cash Ball. The total number of possible outcomes is 60^5 (60 choices for each of the five numbers) times 4 (for the Cash Ball). So the probability of winning the jackpot is 1/(60^5 * 4). (b) To win $1000 a week for life, the player needs to match only the five numbers, without considering the Cash Ball. The total number of possible outcomes for this scenario is 60^5. Therefore, the probability of winning $1000 a week for life is 1/(60^5).

how much variance between two variables has been explained by a correlation of .9?
Answers
A correlation of .9 indicates that 81% of the variance between two variables has been explained.
Correlation measures the strength of the relationship between two variables. A perfect positive correlation is 1.0, indicating that the two variables move in the same direction together. A perfect negative correlation is -1.0, indicating that the two variables move in opposite directions. A correlation of 0 indicates no relationship between the two variables.
To determine the proportion of variance explained by a correlation, you need to square the correlation coefficient (in this case, 0.9). This is called the coefficient of determination (R^2). So, you calculate:
R^2 = (0.9)^2 = 0.81
Thus, a correlation of 0.9 explains 81% of the variance between the two variables.

What is the slope of a line perpendicular to the line whose equation is 2x+4y=-64

Determine the equation of the tangent to the curve defined by 2x y=1-xe²x at x = 0.
Answers
The equation of tangent to the curve at x = 0 is y = -x - 1/2.
To find the equation of the tangent to the curve at x = 0, we need to find the slope of the curve at that point
First, let's differentiate the equation with respect to x:
d/dx (2xy) = d/dx (1 - xe²ˣ)
Using the product rule, we get
2y + 2x(dy/dx) = -e²ˣ - 2xe²ˣ
Now, let's substitute x = 0 into this equation:
2y + 0(dy/dx) = -1 - 0
Simplifying, we have:
2y = -1
Dividing both sides by 2, we get:
y = -1/2
So, at x = 0, the y-coordinate of the curve is -1/2.
Now, we can find the slope of the tangent at x = 0 by differentiating the curve equation
dy/dx = d/dx (1 - xe²ˣ)
dy/dx = -e²ˣ - 2xe²ˣ
Substituting x = 0 into this equation, we get:
dy/dx = -1
Therefore, the slope of the tangent at x = 0 is -1.
Now, we have a point (0, -1/2) and a slope of -1. We can use the point-slope form of a linear equation to find the equation of the tangent:
y - y₁ = m(x - x₁)
Substituting the values, we have
y - (-1/2) = -1(x - 0)
y + 1/2 = -x
Simplifying, we get
y = -x - 1/2
So, the equation of tangent to the curve at x = 0 is y = -x - 1/2.
