Answer:

6 miles

Step-by-step explanation:

Let the route length be r.  The distance the cyclist has already covered is then (5/7)r + 40.  This plus 0.75r - 118 must = r, the length of the entire route.

Then:

(5/7)r + 40 + (3/4)r - 118 = r

The LCD of the fractions 5/7 and 3/4 is 28.  We thus have:

(20/28)r + 40 + (21/28)r - 118 = r, or

(41/28)r - 78 = (28/28)r

Combining the r terms, we get 13r = 78, and so r = 78/13 = 6.

The cyclist's bike route is 6 miles long.

Answer:

sin Ф = 3/√13; cos Ф = 2/√13; and tan Ф = 3/2

Step-by-step explanation:

Let's assume we're limiting ourselves to Quadrant I.

Start with the tangent function.  tan Ф = opp / adj.

In this case opp = 3 and adj = 2.  

The length of the hypotenuse is found using the Pythagorean Theorem and is √(3² + 2²) = √13.

Then sin Ф = opp / hyp = 3/√13 or 3√13/13

and

cos Ф = adj / hyp = 2/√13 or 2√13/13

and (as before)

tan Ф =  opp / adj = 3/2

sin(θ) is approximately 0.832

cos(θ) is approximately 0.555

tan(θ) is 1.5

The given parameters are;

The location of point (2, 3) = The terminal side of angle θ in standard position

The required parameters;

sin of θ, cosine of θ, and tangent of θ

Strategy;

Draw angle θ on the coordinate plane based on definition showing point (2, 3) on the terminal side and find the required trigonometric ratio

Standard position is the position of an angle that has the vertex at the

origin, the fixed side of the angle is on the x-axis and the terminal side

which defines the angle is drawn relative to the initial fixed side to form

the given angle either clockwise or anticlockwise

We have the following trigonometric ratios with regards to the reference angle;

[tex]sin\angle X = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]

The hypotenuse length = √(2² + 3²) = √13

Therefore;

[tex]\mathbf{sin( \theta)} = \dfrac{3 - 0}{\sqrt{13} }= \dfrac{3}{\sqrt{13} } = \mathbf{\dfrac{3 \cdot \sqrt{13} }{13}}[/tex]

[tex]\mathbf{sin( \theta)} \ is \ \mathbf{\dfrac{3 \cdot \sqrt{13} }{13}} \approx 0.832[/tex]

[tex]cos\angle X = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]

Therefore

[tex]\mathbf{cos( \theta)} = \dfrac{2 - 0}{\sqrt{13} }= \dfrac{2}{\sqrt{13} } =\mathbf{ \dfrac{2 \cdot \sqrt{13} }{13 }}[/tex]

[tex]\mathbf{cos( \theta)} \ is \ \mathbf{ \dfrac{2 \cdot \sqrt{13} }{13 }} \approx 0.555[/tex]

[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}[/tex]

The hypotenuse length = √(2² + 3²) = √13

Therefore;

[tex]\mathbf{tan( \theta)} = \dfrac{3 - 0}{2 - 0 } \mathbf{=\dfrac{3}{2 }}[/tex]

tan(θ) = 1.5

Answer:

The volume of the larger pyramid is equal to [tex]7,133\ cm^{3}[/tex]

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

Let

z----> the scale factor

In this problem, the ratio of the height is equal to the scale factor

[tex]z=\frac{4}{7}[/tex]

step 2

Find the volume of the larger pyramid

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z----> the scale factor

x----> volume of the smaller pyramid

y----> volume of the larger pyramid

[tex]z^{3}=\frac{x}{y}[/tex]

we have

[tex]z=\frac{4}{7}[/tex]

[tex]x=1,331\ cm^{3}[/tex]

substitute

[tex](\frac{4}{7})^{3}=\frac{1,331}{y}\\ \\(\frac{64}{343})=\frac{1,331}{y}\\ \\y=343*1,331/64\\ \\y=7,133\ cm^{3}[/tex]

Answer:

x=3

y=21

Step-by-step explanation:

To use substitution method, first we need to decide which variable solve first, either x or y.

Here we decide to start by 'y' using equation y=x+18, which is already solved for 'y'

That same equation is then substitute into the first equation:

x+18= 10x-9

From here, we isolate 'x' variable and grouping terms, we have this:

27=9x

Resulting x=3

Now, we can use the above result in the second equation (y=x+18)

Leading to y=3+18=21.

Final answer:

The period of a sinusoidal function is the amount of time it takes for the function to complete one full cycle.

Explanation:

The period of a sinusoidal function is the amount of time it takes for the function to complete one full cycle. In this case, if the period of the sinusoidal function is 18, then the function will complete one full cycle every 18 units of time. This means that after 18 units of time, the function will have returned to its starting point.

For example, if we have a sinusoidal function f(x) = sin(x), then the period of this function is 2π, because it takes 2π units of time for the function to complete one full cycle. In general, the period of a sinusoidal function can be calculated using the formula T = 2π/ω, where T is the period and ω is the angular frequency.

Answer:

Center : (2,-3)

Radius : sqrt(6)

Step-by-step explanation:

Rewrite this is standard form to find the center and radius.

(x-2)^2 + (y+3)^2 = 6

From this, we can determine that the center is (2,-3) and the radius is sqrt(6)

Answer:

center is (2,-3)

Radius =[tex]\sqrt{6}[/tex]

Step-by-step explanation:

[tex]2x^2-8x+2y^2+12y+14=0[/tex]

To find out the center and radius we write the given equation in

(x-h)^2 +(y-k)^2 = r^2 form

Apply completing the square method

[tex]2x^2-8x+2y^2+12y+14=0[/tex]

[tex](2x^2-8x)+(2y^2+12y)+14=0[/tex]

factor out 2 from each group

[tex]2(x^2-4x)+2(y^2+6y)+14=0[/tex]

Take half of coefficient of middle term of each group and square it

add and subtract the numbers

4/2= 2, 2^2 = 4

6/2= 3, 3^2 = 9

[tex]2(x^2-4x+4-4)+2(y^2+6y+9-9)+14=0[/tex]

now multiply -4 and -9 with 2 to take out from parenthesis

[tex]2(x^2-4x+4)+2(y^2+6y+9)+14-8-18=0[/tex]

[tex]2(x-2)^2 +2(y+3)^2 -12=0[/tex]

Divide whole equation by 2

[tex](x-2)^2 +(y+3)^2 -6=0[/tex]

Add 6 on both sides

[tex](x-2)^2 +(y+3)^2 -6=0[/tex]

now compare with  equation

(x-h)^2 + (y-k)^2 = r^2

center is (h,k)  and radius is r

center is (2,-3)

r^2 = 6

Radius =[tex]\sqrt{6}[/tex]

Answer:

x = 20

∠B = 92

∠C = 40

Step-by-step explanation:

im pretty sure

Answer:

x = 20. ∠B = 92° and ∠C = 40°

Step-by-step explanation:

Angles of a triangle are ∠A = 48°, ∠B = (6x - 28)° and ∠C = (2x)°

Since sum of all the angles of the triangle is 180°

So ∠A + ∠B + ∠C = 180°

48° + (6x - 28)° + (2x)° = 180°

48 + 6x - 28 + 2x = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = [tex]\frac{160}{8}=20[/tex]

Now ∠B = (6x - 28) = 6×20 - 28

∠B = 120 - 28 = 92°

And ∠C = 2x° = 2×20 = 40°

Therefore, x = 20. ∠B = 92° and ∠C = 40° is the answer.

Answer:

Step-by-step explanation:

The definitions of rigid-motion transformations need to be precise as they entail more than physical descriptions of motions. They have unique mathematical definitions and are important for understanding and interpreting real-world movements and physical phenomena.

The definitions of each rigid-motion transformation, namely slides (translations), flips (reflections), and turns (rotations), need to be more precise because they are not solely about the physical manifestation of the motion. These transformations have distinct mathematical underpinnings. For instance, a translation involves moving the figure along a specified direction and distance in a straight line, without changing the orientation of the figure. A reflection involves 'flipping' the figure over a line of reflection, altering its orientation but not its shape or size. A rotation involves turning the figure around a specified point for a given angle.

Moreover, in both rotational and translational motion - two forms of rigid-body motion, there are accurate variables such as displacement, velocity, and acceleration related to translational motion and the corresponding angular variables in rotational motion. These specific definitions are crucial for the mathematics behind movement and interpreting the world around us. Understanding such concepts can also aid in studying physical phenomena as diverse as a spinning ballet dancer or a rotating planet.

Answer:

1 is 27

Step-by-step explanation:

The expression (2−2n)−(5n−27) is not positive for any natural values of n, because when simplified, the inequality n < −(25/7) suggests n would need to be a negative value, which is not possible for natural numbers.

To determine for which natural values of n the expression (2−2n)−(5n−27) is positive, we must solve for the values of n that make the expression greater than zero. Simplifying, we get:

2 − 2n − 5n − 27 > 0

−7n − 25 > 0

Since we have a negative coefficient for n, as n increases, the value of the left side of the inequality decreases. To find the values of n that satisfy the inequality, we isolate n:

−7n > 25

n < −(25/7)

Considering n must be a natural number (positive integer), there are no natural values of n that satisfy the inequality, as natural numbers are always non-negative, and our inequality requires n to be less than a negative number.

Final answer:

The probability that three people independently select the same letter of the alphabet is 1/676.

Explanation:

The question asks about the probability that three people select the same letter of the alphabet independently. Since there are 26 letters in the alphabet, the first person can pick any letter with a probability of 1 (they are sure to pick some letters). The second person must pick the same letter as the first, which has a probability of 1/26. Similarly, the third person also has a probability of 1/26 to pick the same letter as the first two. To find the combined probability for all three events happening in sequence (all three picking the same letter), we multiply the individual probabilities: 1 * (1/26) * (1/26) = 1/676.
