The inner surface area of the vessel, given the diameter of the hemisphere and the total height, is 133π cm².

To find the inner surface area of the vessel, we will consider the hemisphere and the cylinder separately, and then sum their inner surface areas.

Hemisphere:

The diameter of the hemisphere is 14 cm, so its radius (r1) is half of that:

r1 = 14 cm / 2 = 7 cm

Inner surface area (hemisphere) = 2 * π * r1² / 2 = π * r1² = π * (7 cm)² = 49π cm²

The radius of the cylinder is the same as the hemisphere's (r2 = r1 = 7 cm). The height (h) of the cylinder can be found by subtracting the height of the hemisphere from the total height of the vessel:

h = total height - hemisphere height = 13 cm - 7 cm = 6 cm

Inner surface area (cylinder) = 2 x π x r2 x h = 2 x π x (7 cm) x (6 cm) = 84π cm²

Total inner surface area = inner surface area (hemisphere) + inner surface area (cylinder)

Total inner surface area = 49π cm² + 84π cm² = 133π cm²

If the car's wheels revolve 10,000 times without slipping, the car will travel approximately 9.92 miles.

The circumference of a circle (which is the distance around it) is given by the formula:

C = πd, where d is the diameter of the circle.

In this case, the diameter of the car's wheels is 20 in., so the circumference of each wheel is:

C = πd

C= π(20 in.) =

C = 20π in.

If the car's wheels revolve 10,000 times without slipping, then the total distance the car travels is:

distance = number of revolutions × circumference

distance = 10,000 × (20π in.)

To convert this distance to miles, we need to divide by the number of inches in a mile, which is 63,360 in.

distance = (10,000 × 20π in.) / 63,360 in./mi

distance = 9.92 miles

Therefore, distance traveled by the car is 9.92 miles.

The cylinder has a radius of 2 times the square root of 5 meters, or roughly 4.5 meters rounded to the nearest tenth.

The formula for the volume of a cylinder is:

V = πr²h

where V is the volume, r is the radius, and h is the height.

In this case, we have:

V = 160π m³

h = 8 m

Substituting these values into the formula, we get:

160π = πr²(8)

Simplifying the equation by canceling out π on both sides, we get:

160 = 8r²

Dividing both sides by 8, we get:

20 = r²

Taking the square root of both sides, we get:

r = √20

Simplifying the radical by factoring out 4, we get:

r = 2√5

To express the radius as a decimal rounded to the nearest tenth, we can use a calculator to get:

r ≈ 4.5

Therefore, the radius of the cylinder is 2√5 meters or approximately 4.5 meters to the nearest tenth.

The object distance is 0, which implies that the object is at the focus of the concave mirror.

For a concave mirror, the magnification is given by the formula:

m = -di/do

where m is the magnification, di is the image distance, and do is the object distance. Since we are given that the magnification is -2.0, we can write:

-2.0 = -di/do

Simplifying this expression, we get:

di = 2do

We can also use the mirror formula for a concave mirror:

1/f = 1/do + 1/di

where f is the focal length of the mirror. Substituting di = 2do and f = -16 cm (since the mirror is concave), we get:

1/-16 = 1/do + 1/(2do)

Multiplying both sides by -16do, we get:

do - 2f = -32

Substituting f = -16 cm, we get:

do - (-32) = -32 + 32

do = 0

This means that the object distance is 0, which implies that the object is at the focus of the concave mirror. This is a valid result, since a concave mirror can form a real, inverted image for an object placed at a distance equal to its focal length. In this case, the magnification would be -1, not -2. So, it is not possible to have a magnification of -2 for an object distance in front of a concave mirror with a focal length of 16 cm.

Answer:

B) 2

Step-by-step explanation:

First, we need to find BD:

by the Pythagorean theorem, (sqrt13)^2 + (sqrt23)^2 = BD^2

we can simplify this to 13+23=BD^2, which means BD^2 = 36, and BD is 6.

Therefore to find BC, we can use the Pythagorean theorem again and create the formula:

(4sqrt2)^2 + BC^2 = 6^2

This simplifies to 32 + BC^2 = 36, which means that BC^2 = 4, and BC = 2.

As per the given commission, the sales price of the property is $405,000.

To do this, we need to break down the commission earned by the agent into two parts: the commission earned on the first $300,000 and the commission earned on the remaining amount. The commission earned on the first $300,000 can be calculated as:

Commission on first $300,000 = 6% of $300,000

Commission on first $300,000 = 0.06 x $300,000

Commission on first $300,000 = $18,000

So, the remaining commission earned by the agent on the amount that exceeds $300,000 is:

Total commission - Commission on first $300,000 = $21,150 - $18,000

Total commission - Commission on first $300,000 = $3,150

Now, we know that the commission earned on the remaining amount is 3% of the sales price that exceeds $300,000. Let's assume the sales price of the property is x. Then we can write the following equation:

3% of (x - $300,000) = $3,150

We can simplify this equation as follows:

0.03(x - $300,000) = $3,150

x - $300,000 = $3,150 / 0.03

x - $300,000 = $105,000

x = $300,000 + $105,000

x = $405,000

We would see a logarithmic sequence of values if we plotted the amount of time Edna spends watching TV weekly on a logarithmic scale.

If we plot the amount of time Edna spends watching TV on a logarithmic scale, we would see a continuous sequence of values that increase as her viewing time increases. Specifically, the sequence would be a logarithmic scale of the number of hours she watches TV per week.

On a logarithmic scale, each increment corresponds to a multiplication by a constant value. For example, if we use a logarithmic scale base 10, then each increment of 1 corresponds to a multiplication by 10. So, if we plot Edna's TV watching time on a logarithmic scale, we would see a sequence of values that increase by a factor of 10 as her TV watching time increases by an order of magnitude.

For example, if Edna watches 2 hours of TV per week, the logarithmic value would be log(2) = 0.3. If she watches 7 hours per week, the logarithmic value would be log(7) = 0.85. If she watches 20 hours per week, the logarithmic value would be log(20) = 1.3. As her viewing time increases, the logarithmic values would continue to increase in a continuous sequence.

Therefore, if we plotted the amount of time Edna watches TV each week on a logarithmic scale, we would see a logarithmic sequence of numbers.

The probability that the newspapers sample will lead it to predict defeat is 92.36%.

To solve this problem, we need to use the binomial distribution formula.

Let's define the following:

X: number of voters in the sample who do not support the budget (i.e., the sample leads to a prediction of defeat).

n: sample size, which is 377.

p: proportion of voters who support the budget, which is 0.54 (since 54% support it, 46% do not support it).

The probability of the sample leading to a prediction of defeat is:

P(X = k) = (n choose a) * pᵃ * (1-p)ⁿ⁻ᵃ

where (n choose a) = n! / (a! * (n-a)!) is the binomial coefficient.

We want to find P(X >= 189), which means that at least 189 voters in the sample do not support the budget.

P(X >= 189) = 1 - P(X < 189)

To calculate P(X < 189), we can use a normal approximation to the binomial distribution, since n is large and p is not too close to 0 or 1.

The mean of the binomial distribution is mu = n * p = 377 * 0.54 = 203.58

The standard deviation is sigma = √(n * p * (1-p)) = √(377 * 0.54 * 0.46) = 10.20

We can standardize X using the z-score formula:

z = (X - mu) / sigma

P(X < 189) = P(z < (189 - 203.58) / 10.20) = P(z < -1.43)

Using a standard normal table or calculator, we can find that P(z < -1.43) = 0.0764.

Therefore, P(X >= 189) = 1 - P(X < 189) = 1 - 0.0764 = 0.9236.

So the probability that the newspaper's sample will lead it to predict defeat is approximately 0.9236, or 92.36%.
