The time taken by Town A to Town B will be 3 hours.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.

Given that at 30 mph a trip from Town A to Town B takes 6 hours.

The time taken will be calculated as,

Total distance = 30 x 6 = 180 meters

Speed = 30 x 2 = 60 mph

The time,

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

2x² + 5x - 3 = 0

Multiply the coeeficient of x² and the constant (-3)

That is 2 ( - 3) = -6

Find the numbers whose sum is 5 and whose product is -6

The number is 6 and -1

Replace 5x by the numbers

2x² + 6x - x - 3 = 0

2x( x + 3) - 1 ( x + 3) = 0

(2x - 1 ) ( x + 3) = 0

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).

We are given the following multiplication problem.

To perform the fractional multiplication, simply multiply the numerators and the denominators

Therefore, the result of the multiplication is 63/64

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

For f-intercept, put x = 0

So the f-intercept is (0,21).

For x-intercepts, put f(x) = 0

So x-intercepts are (3,0),(-7,0) and (1,0).

Final Answer:

f-intercept: (0,21)

x-intercept: (3,0),(-7,0),(1,0).

Answer:

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).

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:

[tex]\implies 8 \dfrac{2}{5}[/tex]

Step-by-step explanation:

when you want to start solving it you will do 16 over 5 * 21/8equals 8 whole number 2/5

it will give you 336 all over 40 if you divide by 8 you will get 42/5 which is 8 whole number 2/5

Answer:

maya is able to make 47 bracelets

Step-by-step explanation:

We have to use the slope formula

Let's replace the points (9,-24) and (13,-21). Where

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.
