Answer:670

Step-by-step explanation:

In Triangle ABC which is an Isosceles triangle. AB = BC where mLB = 34° so mLA = 73°

Triangles that have at least two sides of equal length are said to be isosceles.

Sum of all angle of a traingle is 180°

So mLA + mLB +mLC = 180

2(mLA) + mLB = 180

2(mLA ) = 180 - 34

2(mLA ) = 146

mLA = 73°

An isosceles triangle has three angles, which, like other triangles, sum up to 180 degrees. The angles other than the apex angle among the three inner angles are identical in size. According to the isosceles triangle theorem, an isosceles triangle has equal-sized angles on either side of its equal sides. As a result, we have B = C in the isosceles triangle ABC where AB = AC.

Answer: 17 units

Step-by-step explanation: A perimeter of a rectangle can be represented by the equation:

2(L)+2(W) = P

L represents length, W represents width and P represents perimeter

Lets say DC is width so AB has to be width aswell and then AD and BC are length.

We are given width and length as equations and P as 76 so we can substitute it into our equation to get:

2(3x-1) + 2(4x-3) = 76

We are trying to solve x so distributing would make it easy to obtain and we get:

6x - 2 + 8x - 6 = 76

Simplifying and solving for x gives us:

6x - 2 + 8x - 6 = 76

14x - 8 = 76

14x = 84

x = 6

Finally, we know AD represents our Width and AD = BC since we know BC is 3x-1, we can plug x in to get BC which is equal to AD to get:

3x - 1 = BC

3(6) - 1 = BC

17 = BC

since BC = AD

17 = AD

The best explanation for the difference between Doctor A’s and Doctor B’s posterior probability for the hypothesis that you have cogscitis is that Doctor A thought the hypothesis that you have cogscitis was more likely than Doctor B before either of them saw the results from Test 1.

After getting the results from Test 1, Doctor A's posterior probability for the hypothesis that you have cogscitis can be calculated as follows:

P(cogscitis|test 1 positive) = (P(test 1 positive|cogscitis) × P(cogscitis)) / P(test 1 positive)

where P(cogscitis) = 0.70 (Doctor A's prior probability) and P(test 1 positive|cogscitis) = 0.70 (probability of positive test result given cogscitis).

P(test 1 positive) can be calculated as the sum of probabilities of getting a positive result for both hypotheses:

P(test 1 positive) = P(test 1 positive|cogscitis) × P(cogscitis) + P(test 1 positive|not cogscitis) × P(not cogscitis)

where P(not cogscitis) = 0.3 (Doctor A's prior probability for not cogscitis).

Substituting the values, we get:

P(cogscitis|test 1 positive) = (0.70 × 0.70) / (0.70 × 0.70 + 0.10 × 0.30) = 0.87 (rounded to two decimal places).

So, Doctor A's posterior probability for the hypothesis that you have cogscitis after seeing the positive result of Test 1 is 0.87.

Similarly, Doctor B's posterior probability for the hypothesis that you have cogscitis after seeing the positive result of Test 1 can be calculated as follows:

P(cogscitis|test 1 positive) = (P(test 1 positive|cogscitis) × P(cogscitis)) / P(test 1 positive)

where P(cogscitis) = 0.20 (Doctor B's prior probability) and P(test 1 positive|cogscitis) = 0.70 (probability of positive test result given cogscitis).

P(test 1 positive) can be calculated as the sum of probabilities of getting a positive result for both hypotheses:

P(test 1 positive) = P(test 1 positive|cogscitis) * P(cogscitis) + P(test 1 positive|not cogscitis) × P(not cogscitis)

where P(not cogscitis) = 0.8 (Doctor B's prior probability for not cogscitis).

Substituting the values, we get:

P(cogscitis|test 1 positive) = (0.70 × 0.20) / (0.70 × 0.20 + 0.10 × 0.80) = 0.15 (rounded to two decimal places).

So, Doctor B's posterior probability for the hypothesis that you have cogscitis after seeing the positive result of Test 1 is 0.15.

The best explanation for the difference between Doctor A’s and Doctor B’s posterior probability for the hypothesis that you have cogscitis is c) Doctor A thought the hypothesis that you have cogscitis was more likely than Doctor B before either of them saw the results from Test 1.

Hence, the correct answer is c.

From observation of the given diagram, the diameter of the circle is the hypotenuse of a right triangle (with legs w and d).  Given that the diameter is 48 cm, substitute the values into Pythagoras' Theorem and rearrange to create an expression for d²:

[tex]\begin{aligned}w^2+d^2&=48^2\\w^2+d^2&=2304\\d^2&=2304-w^2\end{aligned}[/tex]

Substitute the found expression for d² into the given strength equation:

[tex]\begin{aligned}s&=kwd^2\\s&=kw(2304-w^2)\end{aligned}[/tex]

Hence showing that s = kw (2304 - w²).

To find the value of w that will maximise the strength of the rectangular beam, first differentiate the equation for s in terms of w:

[tex]\begin{aligned}s&=kw(2304-w^2)\\s&=2304kw-kw^3\\\implies \dfrac{\text{d}s}{\text{d}w}&=2304k-3kw^2\\&=3k(768-w^2)\end{aligned}[/tex]

Set the differentiated equation to zero and solve for w:

[tex]\begin{aligned}3k(768-w^2)&=0\\ 768-w^2&=0\\w^2&=768\\w&=\sqrt{768}\\w&=\sqrt{256 \cdot 3}\\w&=\sqrt{256}\sqrt{3}\\w&=16\sqrt{3}\\\end{aligned}[/tex]

Substitute the value of w that maximises the strength of the beam, together with the given hypotenuse of 48 cm, into Pythagoras' Theorem and solve for d:

[tex]\begin{aligned}w^2+d^2&=48^2\\768+d^2&=2304\\d^2&=2304-768\\d^2&=1536\\d&=\sqrt{1536}\\d&=\sqrt{256 \cdot 6}\\d&=\sqrt{256}\sqrt{6}\\d&=16\sqrt{6}\end{aligned}[/tex]

The method of cylindrical shells can be used to set up the integral for the solid's volume after rotating the first quarter region defined by the curves y = tan² x, y = 3, and x = 0 about the line y = 3.

We must take into account an infinitesimally thin strip of width dx at a distance x from the y-axis in order to set up the integral.

This cylindrical shell's volume can be estimated by multiplying its height, radius, and thickness (dx) together. Consequently, each shell's volume is as follows:

dV = 2πx(3 - tan²(x)) dx

Setting 3 = tan²(x), we have:

tan²(x) = 3

tan(x) = √3

x = arctan(√3)

Thus, the integral for the volume of the solid is: V = ∫[0, arctan(√3)] 2πx(3 - tan²(x)) dx

rAnswer: x-intercept: (-0.75, 0)

y-intercept: (0, 3/7)

Step-by-step explanation: An x and y intercept is the point when the line crosses the x and y axis respectively. When a line crosses the x axis, the y value is 0 and when the line crosses y axis, the x value is 0. This means   we can set y and x equal to 0 and solve for the other variable.

To solve for the x intercept, we set y equal 0 so:

-4x + 7(0) = 3

-4x = 3

x = -(3/4)

so we get

(-3/4, 0) or (-0.75, 0) for our x int

For the y intercept we set x equal 0:

-4(0) + 7y = 3

7y = 3

y = 3/7

so we get

(0, 3/7) for our y int

The quadratic function with vertex (-1,-6), that passes through (1,2), is given as follows:

y = 2x² + 4x - 4.

The equation of a quadratic function, of vertex (h,k), is given by the following rule:

y = a(x - h)² + k

In which:

Considering the vertex at x = -1, y = -6, the parameters h and k are given as follows:

h = -1, k = -6.

Hence:

y = a(x + 1)² - 6.

When x = 1, y = 2, hence the leading coefficient a is obtained as follows:

2 = a(2)² - 6

4a = 8

a = 2.

Hence:

y = 2(x + 1)² - 6.
