Answer:

The value of f(3) is 8 ⇒ D

Step-by-step explanation:

Let us solve the question

∵ The given figure represents the function f(x)

→ That means every point on the graph represents f(x) = y

∴ f(x) = y

∵ We need to find f(3)

→ That means we need the value of y at x = 3

∴ x = 3

Look at the graph and find the y-coordinate of the point that lies on the curve and has x-coordinate = 3

→ Each small square on the x-axis represents 1 unit, and on the y-axis

   represents 2 units

∵ There is a point on the graph that has x-coordinate = 3

∵ The y-coordinate of this point is 8

∴ The point (3, 8) lies on the graph of f(x)

∴ x = 3 and y = 8

∴ f(3) = 8

∴ The value of f(3) is 8

A 10-sided figure has a total interior angle measurement of 1440°. Each inner angle is 144° in length.

The sum of the measures of the interior angles of a 10-sided figure is 1440°. This is because the sum of the interior angles of any polygon is equal to (n – 2) × 180°, where n is the number of sides of the polygon. Therefore, for a 10-sided figure, the sum of the measures of the interior angles is (10 – 2) × 180° = 1440°. Each interior angle of a 10-sided figure is equal to 144°, which is calculated by dividing the total sum (1440°) by the number of sides (10). Thus, the sum of the measures of the interior angles of a 10-sided figure is 1440° and each interior angle has a measure of 144°.

The radius of convergence, denoted as r, of the series ∑(n=1 to infinity) (-1)^n * x^n / 7^n is 7.

The radius of convergence can be determined using the ratio test, which states that for a power series ∑(n=0 to infinity) a_n * (x - c)^n, if the limit of the absolute value of (a_(n+1) / a_n) as n approaches infinity exists, then the series converges if the limit is less than 1 and diverges if the limit is greater than 1.

In this case, a_n = (-1)^n / 7^n, and we can apply the ratio test:

|(-1)^(n+1) * x^(n+1) / 7^(n+1)| / |(-1)^n * x^n / 7^n| = |x / 7|

As n approaches infinity, the absolute value of (x / 7) remains constant. Thus, for the series to converge, |x / 7| < 1, which implies that |x| < 7. Therefore, the radius of convergence is 7.

Note that the endpoints of the interval of convergence should be checked separately to determine if the series converges at those points.

Step-by-step explanation:

The distance around the running track is calculated as:

Perimeter of the first semi circle + Perimeter of the second circle +50m + 50m

Semi circle has a length or diameter of = 30m

r = 30/2 = 15m

Perimeter of a circle = 2πr

Hence for a semi circle = 2πr/2 = πr

Perimeter of the first semi circle = π × 15

= 47.123889804m

Perimeter of the second semi circle is the same hence,

π × 15 = 47.123889804m

The distance around the running track

Step-by-step explanation:

b is 10 times bigger than c. the ratio A:b is equivalent to the ratio a:c multiplied by 5: A:b = (a:c) * 5

To determine how many times b is bigger than c, we need to compare their respective ratios.

Given:

A:b = 1:5

a:c = 2:1

To make a comparison, we can find the relative sizes of b and c by considering the ratios they have with other variables.

From the ratio A:b = 1:5, we can rewrite it as A:b = 2:10 (multiplying both sides by 2).

Comparing the ratios A:b and a:c, we can see that the ratio A:b is equivalent to the ratio a:c multiplied by 5:

A:b = (a:c) * 5

Substituting the given ratios, we have:

2:10 = (2:1) * 5

Now, we can compare the values of b and c directly:

b = 10

c = 1

Therefore, b is 10 times bigger than c.

It is in the 10 thousandths place

a)  The x-intercepts of the graph of f(x) are x = 2.5 and x = -1.

b) The coordinates of the vertex are (0.75, -5.125).

c) By using the x-intercepts and vertex obtained in Parts A and B, we can accurately depict the shape and positioning of the parabolic graph of f(x).

Part A: To find the x-intercepts of the graph of f(x), we set f(x) equal to zero and solve for x.

Setting f(x) = 0:

\(2x^2 - 3x - 5 = 0\)

To solve this quadratic equation, we can either factor it or use the quadratic formula. In this case, factoring is not straightforward, so let's use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

For our equation, a = 2, b = -3, and c = -5. Substituting these values into the quadratic formula:

x = (-(-3) ± √((-3)^2 - 4(2)(-5))) / (2(2))

x = (3 ± √(9 + 40)) / 4

x = (3 ± √49) / 4

x = (3 ± 7) / 4

This gives us two possible solutions:

x1 = (3 + 7) / 4 = 10/4 = 2.5

x2 = (3 - 7) / 4 = -4/4 = -1

Therefore, the x-intercepts of the graph of f(x) are x = 2.5 and x = -1.

Part B: To determine whether the vertex of the graph of f(x) is a maximum or minimum, we need to consider the coefficient of the x^2 term in the function f(x). In this case, the coefficient is positive (2), which means the parabola opens upward and the vertex represents a minimum point.

To find the coordinates of the vertex, we can use the formula x = -b / (2a). In our equation, a = 2 and b = -3:

x = -(-3) / (2(2))

x = 3 / 4

x = 0.75

To find the corresponding y-coordinate, we substitute x = 0.75 into the function f(x):

f(0.75) = 2(0.75)^2 - 3(0.75) - 5

f(0.75) = 2(0.5625) - 2.25 - 5

f(0.75) = 1.125 - 2.25 - 5

f(0.75) = -5.125

Therefore, the coordinates of the vertex are (0.75, -5.125).

Part C: To graph the function f(x), we can follow these steps:

Plot the x-intercepts obtained in Part A: (2.5, 0) and (-1, 0).

Plot the vertex obtained in Part B: (0.75, -5.125).

Determine if the parabola opens upward (as determined in Part B) and draw a smooth curve passing through the points.

Extend the curve to the left and right of the vertex, ensuring symmetry.

Label the axes and any other relevant points or features.

By using the x-intercepts and vertex obtained in Parts A and B, we can accurately depict the shape and positioning of the parabolic graph of f(x).

The x-intercepts help determine where the graph intersects the x-axis, and the vertex helps establish the lowest point (minimum) of the parabola. The resulting graph should show a U-shaped curve opening upward with the vertex at (0.75, -5.125) and the x-intercepts at (2.5, 0) and (-1, 0).

Step-by-step explanation:

The expectation and variance of the length of the hypotenuse are 2√2 / 3 and 2/9, respectively.

Let X be the side length of the isosceles right triangle. Then, the length of the hypotenuse is H = X√2. We want to find the expectation and variance of H.

The probability density function of X is f(x) = 2x for 0 < x < 1, and f(x) = 0 otherwise, since X is uniformly distributed on (0,1).

To find the expected value of H, we use the formula for the expected value of a function of a random variable:

E[H] = E[X√2] = √2 E[X]

To find the variance of H, we use the formula for the variance of a function of a random variable:

Var(H) = Var(X√2) = 2 Var(X)

where we have used the fact that X and √2 are constants, so their covariance is zero.

To find Var(X), we use the formula for the variance of a continuous random variable:

Var(X) = E[X^2] - (E[X])^2

We already know E[X], so we need to find E[X^2]. To do this, we integrate X^2 times the probability density function over the range (0,1):

E[X^2] = ∫[0,1] x^2 f(x) dx = ∫[0,1] 2x^3 dx = 1/2

Therefore, Var(X) = E[X^2] - (E[X])^2 = 1/2 - (2/3)^2 = 1/18.

Finally, we have:

Var(H) = 2 Var(X) = 2/9.

Therefore, the expectation and variance of the length of the hypotenuse are 2√2 / 3 and 2/9, respectively.

Step-by-step explanation:

Given the equation

\(y=-\frac{1}{2}x\)

comparing the equation with the slope-intercept form

\(y=mx+b\)

Here,

so the slope of the line is -1/2

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

the slope of the perpendicular line will be: 2

Therefore, the point-slope form of the equation of the perpendicular line that goes through (-2, 3) is:

\(y-y_1=m\left(x-x_1\right)\)

substituting the values m = 2 and the point (-2, 3)

\(y-3=2\left(x-\left(-2\right)\right)\)

\(y-3=2\left(x+2\right)\)

Add 3 to both sides

\(y-3+3=2\left(x+2\right)+3\)

\(y=2x+7\)

The correct answer is the value x such that: P(X ≥ x) = 0.95

(a) The sum of independent exponential variables with the same rate parameter follows a gamma distribution. In this case, since each T_i follows an exponential distribution with a rate parameter of 1/100 (mean of 100), the sum ∑_{i=1}^{10} T_i follows a gamma distribution with shape parameter k = 10 and scale parameter θ = 100. Therefore, ∑_{i=1}^{10} T_i ∼ Gamma(10, 100).

(b) To find the probability of successful operation for at least 1.5 years, we need to calculate the cumulative distribution function (CDF) of the gamma distribution at 1.5 years (547.5 days). Using the gamma CDF, denoted by F_X(x), we have:

P(X ≥ 547.5) = 1 - F_X(547.5)

Using the gamma CDF with shape parameter k = 10 and scale parameter θ = 100, we can calculate this probability.

(c) To determine the number of spares needed to be 95% sure of successful operation for at least two years, we need to find the point where the cumulative distribution function (CDF) of the gamma distribution is 0.95. In other words, we need to find the value x such that: P(X ≥ x) = 0.95
