What is equivalent to (1/2)^-2t

Mathematics

oksano4ka [1.4K]3 years ago

Answer:

4^t

Step-by-step explanation:

Given expression is (\frac{1}{2})^{-2t}

To simplify this we apply exponential property

If we have negative exponent at the top then we flip the fraction

that is we take reciprocal of the base 1/2

so 1/2 becomes 2/1 = 2

The expression becomes 2^{2t}

Now we simplify it further

2^2= 2*2= 4

2^{2t}=4^t

fiasKO [112]
<span>1 Liter = 1.05 quart. 1/1.05 Liter = 1.05/1.05 quart = 1 quart. Replacing this value of quart in the equation below. 1 gallon = 4 quarts 1 gallon = 4 * 1/1.05 Liters 1 gallon = 3.80952380952 Total oil consumption per year in gallons is 600,000,00 So, total oil consumption per year in liters is obtained by: 600,000,000 * 3.80952380952 = 2285714285.71 liters Converting to scientific notation, we have 2.28571 * 10^9 liters.</span>

Find the area of the shaded segment of the circle.
vredina [299]

Answer:

Around 5.5 square meters

Step-by-step explanation:

You can start by finding the area of the segment. Since the rest of the circle that is not in the segment is 240 degrees, the segment is 120 degrees or a third of the circle. You can therefore find the area of that segment with the formula \frac{1}{3} \pi r^2 =3\pi square meters. Now, you need to find the area of the triangle inside the sector. This is more difficult than last time, because it is not a 90 degree angle. However, you can solve this by dividing this triangle into two 30-60-90 triangles, which you know how to find the ratio of sides for. In a 30-60-90 triangle, the hypotenuse is twice the length of the smallest leg, and the larger leg is \sqrt{3} times larger than the smaller leg. In this case, these dimensions are a base of \frac{3}{2} for the smaller leg and \frac{3\sqrt{3}}{2} for the larger leg, or the base. Using the triangle area formula and multiplying by 2 (because remember, we divided the big triangle in half), you get \frac{9\sqrt{3}}{4} square meters. Subtracting this from the area of the segment, you get about 5.5 square meters. Hope this helps!
