▪︎Side 15 cm, 18 cm and x cm form a right angle triangle.

We know that :

\( =\tt {hypotenuse}^{2} = {leg}^{2} + {leg}^{2} \)

Which means :

\( =\tt {15}^{2} + {x}^{2} = {18}^{2} \)

\( =\tt 225 + {x}^{2} = 324\)

\( =\tt {x}^{2} = 324 - 225\)

\( = \tt {x}^{2} = 99\)

\(\color{plum} =\tt x = 9.9 \: cm\)

Thus, x (radius) = 9.9 cm

We know that :

\(\color{hotpink}\tt \: Surface \: area \: of \: cone \color{plum}=\pi r(r + \sqrt{ {h}^{2} + {r}^{2} } \)

Then, the surface area of this cone :

\( = \tt3.14 \times 9.9 \times( 9.9 + \sqrt{ {15}^{2} + {9.9}^{2} } )\)

\( =\tt 3.14 \times 9.9 \times( 9.9 + \sqrt{323.01} )\)

\( =\tt 3.14 \times 9.9 \times (9.9 + 18)\)

\( =\tt 3.14 \times 9.9 \times 27.9\)

\( = \tt31.09 \times 27.9\)

\(\color{plum} =\tt\bold{ 867.4 \: cm}\)

Therefore, the surface area of this cone = 867.4 cm

The solutions to the system of congruences are x ≡ 17 (mod 210) and x ≡ 47 (mod 210).

To find all solutions to the system of congruences, we can use the Chinese remainder theorem construction. In this case, we have three congruences: x ≡ 1 (mod 7), x ≡ 2 (mod 5), and x ≡ 5 (mod 6).

Find the product of the moduli. In this case, the product is 7 * 5 * 6 = 210.

For each congruence, divide the product by the modulus and find the multiplicative inverse. Then multiply it by the residue and the quotient obtained from dividing the product by the modulus. Finally, sum up all the results.

For the first congruence, x ≡ 1 (mod 7), we divide 210 by 7 to get 30. The multiplicative inverse of 30 (mod 7) is 4, so we have 4 * 1 * 30 = 120.

For the second congruence, x ≡ 2 (mod 5), we divide 210 by 5 to get 42. The multiplicative inverse of 42 (mod 5) is 3, so we have 3 * 2 * 42 = 252.

For the third congruence, x ≡ 5 (mod 6), we divide 210 by 6 to get 35. The multiplicative inverse of 35 (mod 6) is 5, so we have 5 * 5 * 35 = 875.

Now, summing up all the results: 120 + 252 + 875 = 1247. To find the solutions within the range of the modulus (210), we take the result modulo 210.

x ≡ 1247 (mod 210) ≡ 17 (mod 210)

Therefore, one solution is x ≡ 17 (mod 210).

To find the second solution, we subtract the modulus (210) from the first solution:

x ≡ 17 - 210 ≡ -193 ≡ 47 (mod 210)

Therefore, the second solution is x ≡ 47 (mod 210).

The function g(x)=-1/2f(x)+3 containing points (a) (0, 4) and (a) (2, 0).

The function g(x) = -1/2f(x) + 3 is obtained by applying certain transformations to the original function f(x) = 3^x - 3.

To find the points on the graph of g(x), we need to substitute the x-values from the given points into the function g(x) and determine the corresponding y-values.

Given:

Original function f(x) = 3^x - 3

Points on f(x): (0, -2) and (2, 6)

To find the points for g(x), we substitute the x-values into g(x) = -1/2f(x) + 3:

1. For the point (0, -2):

g(0) = -1/2f(0) + 3

      = -1/2(-2) + 3

      = 1 + 3

      = 4

2. For the point (2, 6):

g(2) = -1/2f(2) + 3

      = -1/2(6) + 3

      = -3 + 3

      = 0

Therefore, the points for the function g(x) = -1/2f(x) + 3 are:

(a) (0, 4)

and

(a) (2, 0)

Hence, the correct answer is:

(a) (0, 4) and (a) (2, 0).

If we divide an 8 by 10 for example, the answer is 0.8, So, when you divide a number by 10, you should move 1 place the decimal point to the left direction.

For example:

The equation of the tangent line to the astroid at the point (-3√3, 1) is: y = -(3√3)^(1/3)x - 3(3√3)^(1/3) + 1

To find the equation of the tangent line to the astroid at the point (-3√3, 1), we need to first find the slope of the tangent line.

We can do this by taking the derivative of the equation of the astroid with respect to x, and then evaluating it at the point (-3√3, 1).

Taking the derivative of x²/³ + y²/³ = 4 with respect to x, we get:

(2/3)x^(-1/3) + (2/3)y^(-1/3) * dy/dx = 0

Solving for dy/dx, we get:

dy/dx = (-x^(1/3))/y^(1/3)

Substituting x = -3√3 and y = 1, we get:

dy/dx = (-(-3√3)^(1/3))/(1^(1/3)) = -(3√3)^(1/3)/1

So the slope of the tangent line at the point (-3√3, 1) is -(3√3)^(1/3).

Now we can use the point-slope form of the equation of a line to find the equation of the tangent line. The point-slope form is:

y - y1 = m(x - x1)

Substituting x1 = -3√3, y1 = 1, and m = -(3√3)^(1/3), we get:

y - 1 = -(3√3)^(1/3)(x + 3√3)

Simplifying, the equation of the tangent line to the astroid at the point (-3√3, 1) is:

y = -(3√3)^(1/3)x - 3(3√3)^(1/3) + 1

Answer:

Add 7 to the first value, 4 to the second, then flip the signs.

Step-by-step explanation:

Well we kind of need the current coordinates but I'll help to the extent I can!

In an ordered pair the first value is the (x) and the second is the (y) .

(x, y)

(x) is always the horizontal line (left & right).

(y) is always the vertical line (up & down).

So if you translate 7 units to the right, you'd add 7 to the (x) [First value in the ordered pair].

If you translate 4 units up, you'd add 4 to the (y) [Second value in ordered pair].

Now, rotating about the origin only changes whether the number is positive or negative.

If you rotate 180° it will just flip both of the values signs.

So if it was positive it becomes negative, if it was negative it becomes positive

Since I don't have the ordered pair I can't give you an answer but I can tell you what to do to get the answer.

Assuming it's a shape, for each point on the shape you will take it's coordinates, add 7 to the (x) and 4 to the (y), then flip the value sign.

Ex: If the starting coordinate was (-6, -3) we would add 7 to the (x), 4 to the (y) and get (-2, 4), flip the signs and end up with (2, -4).

The given statement When inserting a value into a partially-filled array in descending order, the insertion position is indeed the index of the first value smaller than the value being inserted is true.

What is partially filled array?

A partially filled array, also known as a sparse array, is an array data structure where not all elements are populated with values. In other words, it is an array that contains empty or uninitialized elements.

When inserting a new value into this sorted array, we start from the beginning and compare the value with each existing element until we find the first element that is smaller. The insertion position for the new value is the index of this first smaller element.

For example, if we have a partially-filled array [10, 8, 5, 3] and we want to insert the value 6 into the array in descending order, we compare 6 with each element from left to right. The first element smaller than 6 is 5, and its index is 2. Therefore, the insertion position for the value 6 would be index 2, resulting in the updated array [10, 8, 6, 5, 3].

The area of the region bounded above by the parabola y =\(x^2\), below by the x-axis, and on the right by the line x = 2 is 8/3 square units

To find the area of this region, we need to integrate the function y =\(x^2\)over the interval [0, 2] with respect to x, since the region is bounded on the right by the line x = 2.

The lower limit of the integral is 0, since the region is bounded below by the x-axis.

Thus,

Area = \(∫[0,2] x²dx\)

Use power rule of integration to evaluate this integral as:

Area = [8/3] from 0 to 2

Area =\((8/3) - (0^3/3)\)

Area = 8/3

Therefore, the area of the region bounded above by the parabola y =\(x^2\), below by the x-axis, and on the right by the line x = 2 is 8/3 square units.

a. P(X < 68) is approximately 0.84.

b. P(X < 22) is approximately 0.77.

c. P(X = 68) is approximately 0.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.

To calculate the probabilities given, we can use the properties of probability distributions for continuous random variables.

a. P(X < 68) can be found by subtracting the probability of X being greater than 68 from 1 (since the total probability sums to 1):

P(X < 68) = 1 - P(X > 68) = 1 - 0.16 = 0.84

Therefore, P(X < 68) is approximately 0.84.

b. P(X < 22) can be found using the given probability distribution:

P(X < 22) = 1 - P(22 ≤ X ≤ 68) = 1 - 0.23 = 0.77

Therefore, P(X < 22) is approximately 0.77.

c. P(X = 68) for a continuous random variable is 0 since the probability at a single point in a continuous distribution is infinitesimally small. Instead, we consider the probability of a range around that point, which is negligible for a single point.

Therefore, P(X = 68) is approximately 0.

Step-by-step explanation:

When a point falls outside of control limits in statistical process control, the probability is quite high that the process is experiencing special cause variation.

In statistical process control (SPC), control limits are used to define the range within which a process is expected to operate under normal or common cause variation. Common cause variation refers to the inherent variability of a process that is predictable and expected.

On the other hand, special cause variation, also known as assignable cause variation, refers to factors or events that are not part of the normal process variation. These are typically sporadic, non-random events that have a significant impact on the process, leading to points falling outside of control limits.

When a point falls outside of control limits, it indicates that the process is exhibiting a level of variation that cannot be attributed to common causes alone. Instead, it suggests the presence of specific, identifiable causes that are influencing the process. These causes may include equipment malfunctions, operator errors, material defects, or other significant factors that introduce variability into the process.

Therefore, when a point falls outside of control limits in statistical process control, it is highly likely that the process is experiencing special cause variation, which requires investigation and corrective action to identify and address the underlying factors responsible for the out-of-control situation.
