A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

We have law of sine of triangle, which states that,

sin X / x = sin Y / y = sin Z / z

where X, Y and Z are three angles of a triangle and x, y and z are the sides opposite to X, Y and Z respectively.

Using this,

Sin V / v = Sin W / w = Sin X / x

Given that, m ∠V = 76° and m ∠W = 44°

m ∠V + m ∠W + m ∠X = 180°

76° + 44° + m ∠X = 180°

m ∠X = 180° - ( 76° + 44° )

m ∠X = 60°

Also, given that, v = 7.9 inches

Sin V / v = Sin X / x

sin (76°) / 7.9 = sin (60°) / x

x = [sin (60°) × 7.9] / sin (76°)

x = [0.866 × 7.9] / 0.970

x = 7.051 ≈ 7.1

Hence the length of the x is 7.1 inches to the nearest 10th of an inch.

Answer:

The formula for the area of a circle is given by Pi * r^2, where r is the radius of the circle. If the area of the circle is 100 Pi, we can solve for the radius:

100 Pi = Pi * r^2

r^2 = 100

r = 10

The formula for the circumference of a circle is given by 2 * Pi * r. Substituting the value of r = 10, we get:

C = 2 * Pi * r = 2 * Pi * 10 = 20 * Pi

So, the circumference of the circle is 20 Pi.

In the experiment, the subject whose behavior is being assessed are observational units. The observational unit in this instance is Harley (Dog).

We will first investigate if canines can comprehend both non-human and human gestures in this investigation. The dogs were placed around 2.5 meters apart from the experimenter so that the researchers could test this. Two glasses were placed one on either side of the experimenter.

A gesture would be made at one of the cups by either the experimenter (pointing, bowing, or staring) or by a non-human object (a mechanical arm pointing, a doll pointing, or a stuffed animal looking). After then, the scientists would observe whether the dog would approach the cup that was pointed out. Six dogs were put to the test. We'll focus on one of the dogs who participated in both of his trial sets.

The four-year-old mixed breed dog was given the name Harley. Each of the ten trials in a set consisted of one gesture and one pair of cups. In order to see if Harley would approach a particular cup, the experimenter bowed toward it during one round of experiments.

Given that,

Earning of Lynette for one hour when she works overtime = $19.50

She worked overtime twice this week.

One day she worked 3 hours of overtime.

Earning on first day = 3 × $19.50 = $58.50

Total earnings for overtime = $146.25

Earnings on second day = $146.25 - $58.50 = $87.75

Answer:

Step-by-step explanation:

The lattice point of the inverse is (3, 0).

To find the lattice points of the inverse of the function f(x), we need to find the points where both x and y are integers.

To find the inverse of the function, we switch the x and y values, then solve for y:

y = log2(-x + 3) - 4

x = log2(-y + 3) - 4

y = 3 - 2^(x + 4)

For x and y to be integers, both 2^x and - 2^(x + 4) must be integers.

This occurs when y is a positive integer and y <= 2, since 2^y becomes larger than 3 for y > 2.

Thus, the only lattice point of the inverse is (3, 0).

Answer:

Step-by-step explanation:

To find the time it takes for the car to travel 950 m, we need to find the time it takes for each segment and add them up. Let's call the travel time for the first quarter t1, and the travel time for the remaining 3 quarters t2.

a) Travel time:

For the first quarter (0 m to 237.5 m), the equation for the velocity can be found using the kinematic equation:

v = v0 + at

where v0 is the initial velocity (0 m/s), a is the acceleration (+5.40 m/s^2), and t is t1.

So,

t1 = (v - v0) / a = (0 - 0) / 5.40 = 0

For the next 3 quarters (237.5 m to 950 m), the equation for the velocity can be found using the kinematic equation:

v^2 = v0^2 + 2ad

where d is the displacement (950 m - 237.5 m = 712.5 m), and a is the acceleration (-1.80 m/s^2).

So,

t2 = sqrt((2ad + v0^2) / a) = sqrt((2 * -1.80 * 712.5 + 0^2) / -1.80) = sqrt(1286.25 / -1.80) = sqrt(709.03) = 26.6 s

Adding t1 and t2 gives the total travel time:

t = t1 + t2 = 0 + 26.6 = 26.6 s

b) Maximum speed:

To find the maximum speed, we need to find the velocity at the halfway point (475 m) by using the kinematic equation:

v = v0 + at

where v0 is the initial velocity (0 m/s), a is the acceleration (+5.40 m/s^2), and t is t1.

So,

v = 0 + 5.40 * (475 / 237.5) = 4.96 m/s

The maximum speed is 4.96 m/s.

Step-by-step explanation:

Let's take the individual terms and convert them to radical form

[tex]5^{\frac{3}{2}} = (5^3)}^{\frac{1}{2}} = 125^{\frac{1}{2}[/tex]

A term raised to the power 1/2 is nothing but the square root of that term

[tex]125^{\frac{1}{2}} = \sqrt{125} = \sqrt{25\cdot 5} = \sqrt{25} \sqrt{5} = 5 \sqrt{5}[/tex]

[tex]x^{\frac{4}{3}} = (x^4)^{\frac{1}{3}} = \sqrt[3]{x^4}[/tex]  since any term raised to 1/3 is the cube root of that term

We can simplify this further by noting [tex]x^4 = x^3 \cdot x[/tex]'

So [tex]\sqrt[3]{x^4} = \sqrt[3]{x^3} x = x\sqrt[3]{x}[/tex]

(f - h) (-4) = 26.

Step-by-step explanation:

First, find the value of f(-4):

f(x) = x² + 4

f(-4) = (-4)² + 4 = 16 + 4 = 20

Next, find the value of h(-4):

h(x) = x-2

h(-4) = -4 - 2 = -6

Finally, subtract h(-4) from f(-4) to find (f - h) (-4):

(f - h) (-4) = f(-4) - h(-4) = 20 - (-6) = 20 + 6 = 26

So (f - h) (-4) = 26.

The probability that in the next ten days, exactly three are rainy days will occur is 0.25028.

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%

Probability = the number of ways of achieving success. the total number of possible outcomes. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .

The formula for probability states that the possibility of an event happening, or P(E), equals the ratio of the number of favorable outcomes to the number of total outcomes. Mathematically, it looks like this: P(E) = favorable outcomes/total outcomes​

Probability p of a rainy day is 0.25

Using binomial theorem,

The Probability that in the next ten days, exactly three are rainy days will occur:

There are 214 distinct paths from (-1,2,0) to (1,3,7) in Euclidean three-space.

We can approach this problem using a combinatorial approach.

Let's say that there are a total of n moves from the starting point (-1,2,0) to the ending point (1,3,7). Then, the number of H moves is nh, the number of V moves is nv, and the number of A moves is na, where nh + nv + na = n.

The starting point (-1,2,0) is (1,1,7) moves away from the ending point in the x, y, and z directions, respectively. Therefore, we have the following constraints:

   nh ≥ 1 (to move from x = -1 to x = 1)

   nv ≥ 1 (to move from y = 2 to y = 3)

   na ≥ 7 (to move from z = 0 to z = 7)

The number of distinct paths from (-1,2,0) to (1,3,7) is simply the number of ways to choose nh, nv, and na moves from n total moves such that the constraints are satisfied. This is equivalent to finding the number of solutions to the equation nh + nv + na = n subject to the constraints.

Using the stars and bars technique, the number of solutions can be calculated as:

C(n - 1, 2) = C(n - 1, n - 3) = C(n - 1, na - 1)

where C(n, k) is the binomial coefficient representing the number of ways to choose k items from a set of n items.

Since na ≥ 7, we can start by setting na = 7 and then increasing it by one to see if there are additional solutions. For na = 7, n = 7 + nh + nv. Therefore, n >= 8 and n <= 14. The number of solutions for each value of n can be calculated using the formula above, and the total number of solutions can be obtained by summing up the results for each value of n.

For example, when n = 8, there are C(7, 2) = 21 solutions, when n = 9, there are C(8, 2) = 28 solutions, and so on. The final answer is the sum of all the solutions, which is:

21 + 28 + 35 + 35 + 28 + 21 + 13 + 6 = 214
