Answer:

8 Mph

Step-by-step explanation:

We can solve this problem by using the Pythagorean theorem, which relates the lengths of the sides of a right triangle. Let's call the speed of the first bicyclist "v1" and the speed of the second bicyclist "v2". After 1.5 hours of riding, the first bicyclist has traveled 1.5v1 miles to the south, and the second bicyclist has traveled 1.5v2 miles to the east. The distance between them is the hypotenuse of a right triangle with legs of length 1.5v1 and 1.5v2:

c^2 = (1.5v1)^2 + (1.5v2)^2

where c is the distance between the two bicyclists, which is given as 12√2 miles. Substituting and simplifying, we get:

(12√2)^2 = (1.5v1)^2 + (1.5v2)^2

288 = 2.25v1^2 + 2.25v2^2

128 = v1^2 + v2^2

We also know that the two bicyclists are traveling at the same speed, so v1 = v2. Substituting this into the equation above, we get:

128 = 2v1^2

v1^2 = 64

v1 = √64 = 8

Therefore, each bicyclist is traveling at a speed of 8 miles per hour.

Step-by-step explanation:

The particle is speeding up after 1.67 seconds.

What is displacement ?

In physics, displacement refers to the distance and direction of an object's change in position from its starting point to its ending point. It is a vector quantity, which means that it has both magnitude and direction.

Displacement is different from distance, which is the total length of the path an object has traveled, regardless of direction. Displacement only considers the straight-line distance and direction between the starting and ending points.

According to given conditions :

To determine when the particle is speeding up, we need to find the acceleration of the particle.

The acceleration of the particle is given by the second derivative of its position function:

a(t) = s''(t) = 6t - 10

The particle is speeding up when its acceleration is positive. So, we need to find the values of t for which a(t) > 0.

Setting a(t) > 0, we have:

6t - 10 > 0

6t > 10

t > 10/6

t > 1.67

Since t ≥ 0, the particle is speeding up when t > 1.67.

Therefore, the particle is speeding up after 1.67 seconds.

Answer:

Approximately 9.23 cm

Step-by-step explanation:

We can start by finding the height of each domino in the chain, starting with domino 0, which is 5.00 cm tall.

Let h be the height of domino 5. Then we can express the height of each domino in terms of h as follows:

Domino 0: 5.00 cm

Domino 1: 1.13 * 5.00 = 5.65 cm

Domino 2: 1.13 * 5.65 = 6.38 cm

Domino 3: 1.13 * 6.38 = 7.21 cm

Domino 4: 1.13 * 7.21 = 8.16 cm

Domino 5: 1.13 * 8.16 = h cm

Since we know that domino 5 is the tallest domino and is number 5 in the sequence, we can set the height of domino 5 equal to h and solve for h:

h = 1.13 * 8.16

h ≈ 9.23 cm

Therefore, the height of domino 5 is approximately 9.23 cm.

Based on the question given, the probability that Federico scores one point in this situation is 0.24, or 24%

Since Federico makes 60% of his free throws, the probability that he makes his first free throw is 0.6. If he makes his first free throw, he will get a second free throw, and the probability that he makes his second free throw is also 0.6.

If he misses his first free throw, he will not get a second free throw, and he will score zero points in this situation.

So, to find the probability that Federico scores one point in this situation, we need to find the probability that he makes his first free throw and misses his second free throw:

P(score 1 point) = P(makes 1st free throw) * P(misses 2nd free throw)

= 0.6 * (1 - 0.6) [since the probability of missing a free throw is 1 minus the probability of making it]

= 0.6 * 0.4

= 0.24

Therefore, the probability that Federico scores one point in this situation is 0.24, or 24%

The volume of the composite solid is 320.7 cubic inches.

A composite solid is a three-dimensional object that is created by combining or "composing" two or simpler three-dimensional shapes, such as prisms, cylinders, pyramids, cones, or spheres. The combined shape may be more complicated or asymmetrical than the sum of its parts, yet it may still be measured and examined using the same geometrical rules and formulas. Cones with a frustum or truncated bases, pyramids with rectangular or triangular bases, and structures created by fusing together cylinders, prisms, or spheres are a few examples of composite solids. In order to build and create complicated structures and objects, composite solids are frequently utilized in architecture, engineering, and manufacturing.

To find the volume of the composite solid, we need to find the volumes of each of its components and add them together.

The volume of a hemisphere with a radius of 5 inches is given by:

V_hemisphere = [tex]\frac{2}{3}\pi r^{3}[/tex] = [tex]\frac{2}{3}\pi 5^{3}[/tex] = 523.6 cubic inches

Since there are two hemispheres, the total volume of the hemispheres is:

V_total_hemispheres = 2V_hemisphere = 2(523.6) = 1047.2 cubic inches

The cylinder has a radius of 5 inches and a length of 13 inches. The volume of a cylinder is given by:

V_cylinder = [tex]\pi r^2h[/tex] = [tex]\pi 5^2(13)[/tex] = 1025.0 cubic inches

The total volume of the composite solid is:

V_total = V_total_hemispheres + V_cylinder = 1047.2 + 1025.0 = 2072.2 cubic inches

Rounding to the nearest tenth, we get:

V_total ≈ 320.7 cubic inches

Therefore, the answer is option (c) 320.7 cubic inches.

We can use the ratio of distance to time for the cheetah's first run to find how long it will take to run 147 meters.

The speed of the cheetah is given by:

Speed = distance/time

In the first run, the cheetah ran 196 meters in 8 seconds, so its speed was:

Speed = 196/8 = 24.5 meters per second

To find out how long it will take for the cheetah to run 147 meters, we can use the speed we just calculated and the distance we want to find:

Speed = distance/time

24.5 = 147/time

Solving for time:

time = 147/24.5

time = 6 seconds

Therefore, it will take the cheetah 6 seconds to run 147 meters.

[tex]16x^2-24x+9[/tex]

Step-by-step explanation:

To find (c circle d)(x), we need to first find d(c(x)) and then simplify.

First, we need to find c(x) and substitute it into d(x), as follows:

d(c(x)) = d(4x - 2) = (4x - 2)^2 + 5(4x - 2)

Expanding the square and simplifying, we get:

d(c(x)) = 16x^2 - 24x + 9

Now, we have (c circle d)(x) = d(c(x)) = 16x^2 - 24x + 9.

Secant can be defined as the reciprocal of cosine. Secant of angle A will be hypotenuse/adjacent.

There are three basic trigonometric ratios. Sin, Cos and Tan.

Sin = opposite side/ hypotenuse

Cos = adjacent side/ hypotenuse

Tan = opposite side/ adjacent side

Here in the give image, Sin(A) = a/c

                                        Cos(A) = b/c

                                        Tan(A) = a/b

There are reciprocals for each trigonometric functions

Cosecant is the reciprocal of sine. Cosec(A) = c/a

Secant is the reciprocal of  Cosine. Sec(A) = c/b

Cotangent is the reciprocal of Tangent . Cot(A) = b/a
