Find the series' interval of convergence and, within this interval, the sum of the series as a function of x . \sum_(n=0)^(\infty ) ((x^(2)+4)/(6))^(n) The interval of convergence is \sum_(n=0)^(\infty ) ((x^(2)+4)/(6))^(n)=, (Simplify your answers. Type exact answers, using radicals as needed.) The sum of the series is \sum_(n=0)^(\infty ) ((x^(2)+4)/(6))^(n)=

Find the length of the arc of the semicubical parabola $y^2 = x^3$ between the points (1, 1) and (16, 64). y (1, 1) (16, 64) $y^2 = x^3$ x SOLUTION For the top half of the curve we have $y = x^{3/2}$ $\frac{dy}{dx} =$ and so the arc length formula gives $L = \int_1^{16} \sqrt{1 + (\frac{dy}{dx})^2} dx = \int_1^{16} \sqrt{ } dx$. If we substitute $u = x + 1$, then $du = dx$. When $x = 1, u = $; when $x = 16, u = $. Therefore, $L = \frac{4}{9} \int_{13/4}^{37} \sqrt{u} du$ $=$ $\frac{4}{9} u^{3/2} \Big|_{13/4}^{37}$ $=$ As a check on our answer to this example, notice from the figure that the arc length ought to be slightly larger than the distance from (1, 1) to (16, 64), which is $\sqrt{4194} \approx 64.761099$

On December 31, 2025, before the books were closed, the management and accountants of Tannery Inc. made the following determinations about three depreciable assets: 1. Depreciable asset X was purchased January 4, 2023. The asset's original cost was $114,000, and this amount was entirely expensed in 2023. This particular asset has a 8-year useful life and no salvage value. The straight-line method was chosen for depreciation purposes. 2. Depreciable asset Y was purchased January 2, 2024. It originally cost $540,000 and, for depreciation purposes, the sum-of-the-years' digit method was originally chosen. The asset was originally expected to be useful for 10 years and have a zero salvage value. In 2025, the decision was made to change the depreciation method from sum-of-the-years' digits to straight-line, and the estimates relating to useful life and salvage value remained unchanged. 3. Depreciable asset Z was purchased January 3, 2021. It originally cost $160,000 and, for depreciation purposes, the straight-line method was chosen. The asset was originally expected to be useful for 8 years and have a zero salvage value. In 2025, the decision was made to extend the total life of this asset to 10 years and to estimate the salvage value at $5,000. Additional data: 1. Income in 2025 before depreciation expense amounted to $316,000. 2. Depreciation expense on assets other than X, Y, and Z totaled $41,000 in 2025. 3. Income in 2024 was reported at $298,000. 4. Ignore all income tax effects. 5. 100,000 shares of common stock were outstanding in 2024 and 2025.

A hot air balloon is rising vertically at a o-paich vijeity. When the hot air balloon reaches point A a few metres above the ground, a man in the hot air balloon drops a ball which hits the ground and bounces. Ignore the effects of friction. GROUND The velocity-time graph below represents the motion of the ball from the instant it is dropped until after it bounces for the first time. The time interval between bounces is ignored. THE UPWARD DIRECTION IS TAKEN AS POSITIVE. USE INFORMATION FROM THE GRAPH TO ANSWER THE QUESTIONS THAT FOLLOW. 3.1 Write down the magnitude of the velocity of the hot air balloon. 3.2 Calculate the height above the ground from which the ball was dropped. Calculate the: 3.3 Time at the point \( \mathbf{P} \) indicated on the graph 3.4 Maximum height thet ball reaches after the first bounce. 3.5 Distance between the ball and hot air balloon when the ball is at its maximum height after the first bounce

Quote - Use the quote to help answer the following questions. President Harry Truman's Message to Congress: The second way of life is based upon the will of a minority forcibly imposed upon the majority. It relies upon terror and oppression, a controlled press and radio; fixed elections, and the suppression of personal freedoms. I believe that it must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures. I believe that we must assist free peoples to work out their own destinies in their own way. I believe that our help should be primarily through economic and financial aid which is essential to economic stability and orderly political processes. 1. In paragraph 1, who is President Truman addressing of being oppressive? 2. In paragraph 2, what countries were requesting assistance from the U.S.? 3. In paragraph 3, what type of government is described? 4. In paragraph 4, what is Truman requesting of Congress?

Problem 6: A rectangular coil consists of N = 100 closely wrapped turns and has dimensions a = 0.4 [m] and b = 0.5 [m]. The coil is hinged along the y axis, and its plane makes an angle $\theta$ = 20° with the x axis. a) What is the magnitude of the torque exerted on the coil by a uniform magnetic field of B = 1.2 [T] directed in the positive x direction when the current is 1.5 [A] in the direction shown? b) What is the expected direction of rotation of the coil?
