Answer:

sec(∠F) = \(\frac{41}{9}\)

Step-by-step explanation:

In triangle EFD,

m∠F = 90°

Adjacent side of ∠E = EF = 9 units

Opposite side of ∠E = DF = 40 units

Hypotenuse = DE = 41 units

For secant of ∠E ,

sec(∠E) = \(\frac{\text{Hypotenuse}}{\text{Adjacent side}}\)

            = \(\frac{41}{9}\)

Therefore, \(\frac{41}{9}\) is the ratio of secant of ∠F.

Step-by-step explanation:

There is no stationary point at x = 2. The nature of the curve at x = 2 cannot be determined since there is no stationary point.

To verify that the curve has a stationary point at x = 2, we need to find the derivative of the equation and set it equal to zero.

Given the equation:

y = 2x + 1/(x-1)²

Let's find the derivative dy/dx:

dy/dx = d/dx [2x + 1/(x-1)²]

To find the derivative, we can use the power rule and the chain rule. Let's differentiate each term separately:

For the first term, 2x, the derivative is 2.

For the second term, 1/(x-1)², we can rewrite it as (x-1)^(-2) to apply the power rule. The derivative is then:

d/dx [(x-1)^(-2)] = -2(x-1)^(-3) * d/dx (x-1)

Using the chain rule, d/dx (x-1) = 1, so the derivative becomes:

-2(x-1)^(-3) * 1 = -2/(x-1)^3

Now, let's set dy/dx equal to zero and solve for x:

-2/(x-1)^3 = 0

This equation is satisfied when the numerator is equal to zero:

-2 = 0

However, -2 is not equal to zero, which means there is no x value that makes dy/dx equal to zero.

Answer:

\(\frac{1}{5} (2x+10)=4\) \(x=5\)

\(\frac{1}{3} (3x+9)=9\) \(x=6\)

Step-by-step explanation:

\(\frac{1}{5} (2x+10)=4\)

Multiply both sides of the equation by 5.

5 · \(\frac{1}{5}\) · \((2x+10)=\) 5 · 4

Simplify both sides of the equation.

\(2x+10=20\)

Subtract 10 from both sides of the equation.

\(2x=10\)

Divide each term by 2 and simplify.

\(x=5\)

--------------------------------------------------------------------

\(\frac{1}{3} (3x+9)=9\)

Substitute x for 6

\(\frac{1}{3} (3(6)+9)=9\)

Multiply 3 · 6

\(\frac{1}{3} ((18)+9)=9\)

Add 18 + 9

\(\frac{1}{3} (27)=9\)

Divide \(\frac{1}{3}\) ÷ 27

9 = 9

Step-by-step explanation:

The completed square form of the quadratic equation y = 2x² - 7x - 4 is:

y = 2(x - 7/8)² - 121/32

We have,

To complete the square of the quadratic equation y = 2x² - 7x - 4, we can follow these steps:

- Rewrite the quadratic equation in the form y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

- To get the value of h, we can use the formula h = -b/2a, where a = 2,

b = -7.

So,

h = -(-7)/2(2) = 7/4

- To get the value of k, we can substitute h into the equation and simplify.

y = 2(x² - (7/4)x) - 4

= 2(x² - (7/4)x + (7/8)²) - 2(7/8)² - 4

= 2(x - 7/8)² - 121/32

Therefore,

The completed square form of the quadratic equation y = 2x² - 7x - 4 is:

y = 2(x - 7/8)² - 121/32

Answer:

180 grams

Step-by-step explanation:

grams of dark chocolate= 200 % cocoa =60%

Grams of milk chocolate: 200 % cocoa=30%

Amount of cocoa in mixture:

(proportion of milk chocolate+ dark chocolate)

(30% of 200)+60% of 200)

(0.3* 200)+(0.6 *200)

60+120

=180 grams

Answer:

\(45\%\)

Step-by-step explanation:

The 200g mixture of dark chocolate is 60% cocoa, meaning there are \(200\cdot 0.6=120\) grams of cocoa in this mixture.

The 200g mixture of milk chocolate is 30% cocoa, meaning there are \(200\cdot 0.3=60\) grams of cocoa in this mixture.

When mixed together there are a total of 200+200=400 grams of content. Of these 400 grams, 120+60=180 of them are cocoa.

Thus, the concentration of cocoa in the resulting mixture is:

\(\frac{180}{400}=\fbox{$45\%$}\)

Answer:

\(\displaystyle \frac{75}{2}\) or \(37.5\)

Step-by-step explanation:

We can answer this problem geometrically:

\(\displaystyle \int^6_{-4}f(x)\,dx=\int^1_{-4}f(x)\,dx+\int^3_1f(x)\,dx+\int^6_3f(x)\,dx\\\\\int^6_{-4}f(x)\,dx=(5*5)+\frac{1}{2}(2*5)+\frac{1}{2}(3*5)\\\\\int^6_{-4}f(x)\,dx=25+5+7.5\\\\\int^6_{-4}f(x)\,dx=37.5=\frac{75}{2}\)

Notice that we found the area of the rectangular region between -4 and 1, and then the two triangular areas from 1 to 3 and 3 to 6. We then found the sum of these areas to get the total area under the curve of f(x) from -4 to 6.

Answer:

\(\dfrac{75}{2}\)

Step-by-step explanation:

The value of a definite integral represents the area between the x-axis and the graph of the function you’re integrating between two limits.

\(\boxed{\begin{minipage}{8.5 cm}\underline{De\:\!finite integration}\\\\$\displaystyle \int^b_a f(x)\:\:\text{d}x$\\\\\\where $a$ is the lower limit and $b$ is the upper limit.\\\end{minipage}}\)

The given definite integral is:

\(\displaystyle \int^6_{-4} f(x)\; \;\text{d}x\)

This means we need to find the area between the x-axis and the function between the limits x = -4 and x = 6.

Notice that the function touches the x-axis at x = 3.

Therefore, we can separate the integral into two areas and add them together:

\(\displaystyle \int^6_{-4} f(x)\; \;\text{d}x=\int^3_{-4} f(x)\; \;\text{d}x+\int^6_{3} f(x)\; \;\text{d}x\)

The area between the x-axis and the function between the limits x = -4 and x = 3 is a trapezoid with bases of 5 and 7 units, and a height of 5 units.

The area between the x-axis and the function between the limits x = 3 and x = 6 is a triangle with base of 3 units and height of 5 units.

Using the formulas for the area of a trapezoid and the area of a triangle, the definite integral can be calculated as follows:

\(\begin{aligned}\displaystyle \int^6_{-4} f(x)\; \;\text{d}x & =\int^3_{-4} f(x)\; \;\text{d}x+\int^6_{3} f(x)\; \;\text{d}x\\\\& =\dfrac{1}{2}(5+7)(5)+\dfrac{1}{2}(3)(5)\\\\& =30+\dfrac{15}{2}\\\\& =\dfrac{75}{2}\end{aligned}\)

Given statement solution is :- The y-intercept is (0, -3).

The term "intercept" refers to the location where a line or curve crosses a graph's axis.

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.

To find the x-intercept, we set y = 0 and solve for x.

0 = (1/4)x - 3

Add 3 to both sides:

3 = (1/4)x

Multiply both sides by 4 to isolate x:

12 = x

So the x-intercept is (12, 0).

We set x = 0 and then solve for y to determine the y-intercept.

y = (1/4)(0) - 3

y = -3

So the y-intercept is (0, -3).

What makes Europa a potential home to extraterrestrial life? *

Europa is the sixth closest moon of the planet Jupiter, and one of the largest moons in the solar system. Europa is slightly smaller than the Earth’s moon and has a tenuous atmosphere compared primarily to oxygen. The surface of Europa is composed of water and is one of the smoothest in the solar system. Scientists suggest that it is possible Europa has an ocean of liquid water beneath its surface, making it a strong candidate for extraterrestrial life. It is also predicted that heat energy from tidal flexing may cause oceans to remain liquid and drives geological activity similar to plate tectonics on Earth.

probability = m/n = 12/15 = (3*4)/(3*5) = 4/5

There must exist a vertex u in T such that the distance between u and v is at most (n-1)/2.

To prove the existence of a vertex u in tree T such that the distance between u and v is at most (n-1)/2, we can employ a contradiction argument. Assume that such a vertex u does not exist.

Since the number of vertices in T is odd, there must be at least one path from v to another vertex w such that the distance between v and w is greater than (n-1)/2.

Denote this path as P. Let x be the vertex on path P that is closest to v.

By assumption, the distance from x to v is greater than (n-1)/2. However, the remaining vertices on path P, excluding x, must have distances at least (n+1)/2 from v.

Therefore, the total number of vertices in T would be at least n + (n+1)/2 > n, which is a contradiction.

Hence, there must exist a vertex u in T such that the distance between u and v is at most (n-1)/2.
