The Greyhound has run to a distance equal to 50.7 miles.

This question can be solved using the distance, speed and time relation. The Distance, Speed and time are related to each other by the relation

Speed = Distance/Time, Let the time travelled be equal to t.

Distance travelled by first bicyclist is equal to 16t and Distance travelled by second bicyclist is equal to 17t. The total distance is equal to 44 miles. So, we get

44 = 17t + 16t

44 = 33t

=> t = 44/33

=> t = 1.3 hours

At this time a greyhound starts running back and forth around each cyclist. The speed of Greyhound is equal to 39 miles per hour. Distance will be given by

Distance = Speed × Time

Distance = 39 × 1.3

Distance = 50.7 miles

Given multiplication:

[tex]3 \dfrac{1}{5} \times 2 \dfrac{5}{8}[/tex]

Convert the mixed numbers into improper fractions by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, and placing the answer over the denominator:

[tex]\implies \dfrac{3 \times 5+1}{5} \times \dfrac{2 \times 8+5}{8}[/tex]

[tex]\implies \dfrac{15+1}{5} \times \dfrac{16+5}{8}[/tex]

[tex]\implies \dfrac{16}{5} \times \dfrac{21}{8}[/tex]

[tex]\textsf{Apply\;the\;fraction\;rule} \quad \dfrac{a}{b} \times \dfrac{c}{d}=\dfrac{ac}{bd}:[/tex]

[tex]\implies \dfrac{16 \times 21}{5 \times 8}[/tex]

[tex]\implies \dfrac{336}{40}[/tex]

Reduce the fraction by dividing the numerator and denominator by the common factor of 8:

[tex]\implies \dfrac{336 \div 8}{40 \div 8}[/tex]

[tex]\implies \dfrac{42}{5}[/tex]

Divide the numerator by the denominator:

[tex]\implies 42 \div 5=8\;\textsf{remainder}\;2[/tex]

The mixed number answer is the whole number and the remainder divided by the denominator:

The polynomial having the above quantities is expressed as x³ - 2x² - 5x + 10 = 0

The above situations will form a Cubic polynomial. A Cubic polynomial function may be defined as an expression which can be written in the form of ax³ + bx² + cx + d = 0 where a, b, c and d are coefficients and x is the independent variable. Since, the polynomial should have real coefficients so its multiplicity will be equal to 1. Now, the roots of the polynomial are given as 2 and √5. Since, square roots always occur in pair so the polynomial will have -√5 as its root. Now, the polynomial formed will be

(x - 2) (x - √5) (x + √5) = 0

(x - 2) (x² - 5) = 0

x³ - 5x - 2x² + 10 = 0

=> x³ - 2x² - 5x + 10 = 0 which is the required polynomial.

The average rate of change of the function f(x) = -2x² - 2 from x = 2 to x = 6 is -16

An equation shows the relationship between two or more numbers and variables.

The average rate of change of a function f(x) over the interval x = a to x = b is given by:

A(x) = [f(b) - f(a)]/[b - a]

Given that function f(x) = -2x² - 2 from x = 2 to x = 6, hence:

f(2) = -2(2)² - 2 = -10

f(6) = -2(6)² - 2 = -74

The average rate of change is:

A = [f(b) - f(a)]/[b - a]

Substituting:

A = [-74 - (-10)] / [6 - 2] = -16

The average rate of change is -16

canThe first First step we need to do is to make the decomposition of the vectors W and P.

Both will have a component perpendicular and parallel to the plane. The perpendicular will be used to calculate the maximum static friction force, and the horizontal will be used to find the P required to prevent the block from sliding.

From the sketch, we are able to define both, parallel and perpendicular components of P, as it follows:

Now, we can do the same for W.

And for W we also can provide the two components as follows:

Now, we can elaborate on both equations: one for the perpendicular direction and the other for parallel. In the perpendicular direction, we have a component of W, one component of P, and the normal force N. Because the block is going to move, or change its movement along this direction, the sum of the forces pointing upwards must be equal to the sum of the forces pointing downwards. From this, we can write the following:

Now, for the horizontal, we have the P component to the right and the W component to the left. If we imagine the block is almost sliding. We can write the following equation, from the premise the forces will cancel each other just like the perpendicular case:

Here it is used the fact that the friction force is equal to the multiplication of the coefficient of static friction by the normal force. Here we assumed also that the friction is maximum because the block is on the verge of motion downwards, and for this reason, the Friction is upwards, with the P component.

Now, substituting N and the coefficient, we find:

From this, we can see that the force P made to the left with an intensity equal to -5.275 lbf will bring the block on the verge of motion downwards. If we consider that P is strong enough to make it almost move upwards, it is, the Normal Force will be downwards, we can remake the calculation as it follows:

And substituting values, we have:

From this, we know that the max value for P, where the block will not slide is going to be 196.46 lbf to the right.

Answer:

  B, C

Step-by-step explanation:

You want to find the equivalent expressions among ...

The relevant rule of exponents is ...

  a^b = (1/a)^-b

Expressions with the same base and different exponents will not be equivalent. (A≠B).

Expressions with different bases and the same exponent will not be equivalent. (A≠C).

A variable in the base cannot replace a variable in the exponent. (A≠D).

The rule of exponents tells us replacing the base by its reciprocal and negating the exponent will result in an equivalent expression. (B=C).

The equivalent expressions are 4^(-3x^2) and (1/4)^(3x^2).

We got the linear equation:

The slope of this line will be -8/5 and the y-intercept will be -4.

To graph it, first find the intercept with x - axis.

The equation of the circle that represents the dartboard is (x - 12)² + (y - 17/3)² = 9/16, where the origin is the lower left corner of the room and the unit of the radius is feet.  

The position of Brian's dart is represented by the coordinates (11.5, 5). Brian's dart does land on the dartboard.

Mathematically, the standard form of the equation of a circle is represented by this mathematical expression;

(x - h)² + (y - k)² = r²

Where:

From the question, we have the following information:

The height of this standard dartboard, k = 5 feet, 8 inches.

The diameter of this standard dartboard = 18 inches.

The bull's eye, h = 12 feet.

Next, we would convert the all of the units in inches to feet as follows:

Height, k = 5 + 8/12

Height, k = 5 + 2/3

Height, k = 17/3 feet.

For the diameter, we have:

Diameter = 18/12

Diameter = 3/2 feet.

Also, we would determine the radius as follows:

Radius, r = diameter/2

Radius, r = (3/2)/2

Radius, r = 3/4 feet.

Substituting the parameters into the standard equation, we have;

(x - 12)² + (y - 17/3)² = (3/4)²

(x - 12)² + (y - 17/3)² = 9/16

Next, we would determine whether Brian's dart land on the dartboard:

(x - 12)² + (y - 17/3)² < 9/16

(x - 12)² + (y - 17/3)² < 9/16

(11.5 - 12)² + (5.5 - 5.67)² < 0.5625

0.25 + 0.0289 < 0.5625

0.2789 < 0.5625 (Yes, it does land because it's within the circumference of this standard dartboard).

To completely define a line we need two points.

We can use the information about the y-intercept and use it as one of the points we need. (0, -3)

As for the second point, we can get the x-intercept by setting y=0 and evaluating the function for x:

Then, we have the points we need: (0, -3) and (6,0).

Now, we only need to mark those points on the plane and draw a line through both of them.

Since the plane in the image only reaches the point (5,0), we need to calculate another point to specifically draw the graph on that grid.

Point-slope form is:

Find the slope:

Use one of the points and the slope to determine the equation of the line:

Answer:

[tex]y-10=\frac{2}{3} (x-5)[/tex]

Step-by-step explanation:

We are given: g(5)=10, and g(2)=8.

The value inside the parentheses is the x value, and the value that it (g(x)) is equal to is the y value.

So, as points, the values are (5, 10), and (2, 8).

The equation wants to be written in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point.

We first want to find the slope of the line.

The slope (m) can be found with two points using the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.

We can label the values of the points we were given.

[tex]x_1=5\\y_1=10\\x_2=2\\y_2=8[/tex]

Now, substitute these values into the formula.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{8-10}{2-5}[/tex]

Subtract.

[tex]m=\frac{-2}{-3}[/tex]

Simplify.

[tex]m=\frac{2}{3}[/tex]

The slope is 2/3.

Since we now have the value of the slope, as well as [tex](x_1, y_1)[/tex], we can plug these values into the formula for point-slope form.

Recall that [tex]x_1=5[/tex] and [tex]y_1=10[/tex]; plug these in for [tex]x_1[/tex] and [tex]y_1[/tex] respectively.

[tex]y-10=m(x-5)[/tex]

We also just found the slope, which is 2/3. Plug that in for m.

[tex]y-10=\frac{2}{3} (x-5)[/tex]
