The thermometer reading would be 73.48°C.

The boiling point of water is generally considered to be 100°C. According to the given information, the temperature of the liquid in the thermometer is 26.52°C lower than the boiling point of water. Therefore, to find the thermometer reading, we subtract 26.52 from 100.

100 - 26.52 = 73.48

Hence, the thermometer reading would be 73.48°C.

In this scenario, we are assuming that the thermometer is calibrated to measure temperature in Celsius. The boiling point of water at standard atmospheric pressure is 100°C, and the given information states that the liquid in the thermometer is 26.52°C lower than the boiling point.

By subtracting 26.52 from 100, we obtain a reading of 73.48°C.

Thermometers work by utilizing the principle that certain substances, such as mercury or alcohol, expand or contract with changes in temperature. The expansion or contraction is measured using a scale, which is marked with various temperature values.

In this case, the thermometer is calibrated in Celsius, so we refer to the Celsius scale. By subtracting 26.52 from 100, we find the temperature at which the liquid in the thermometer is settled, which is 73.48°C.

Two triangles are similar if they have the same ratio of corresponding sides and equal pairs of corresponding angles.

For the triangle and its image provided in the question to be similar, the angle measures must be equal and the corresponding side ratios must be equal as well, such that:

Assuming the angles are unchanged by the transformation, we can consider the side lengths:

Therefore, the scale factor will be:

Hence, the two figures are similar because the angle measures are equal and each side length of the image is 3/2 times the corresponding side length of the preimage.

OPTION C is the correct option.

Angle ADC and angle BDC are supplementary angles.

A pair of complimentary angles is angle ACD and angle BCD.

If two angels are supplementary angles, it means their sum equals to 180 degrees. Two angles on a straight line are usually linear pair which are supplementary to each other. That is, they have a sum of 180 degrees.

When two angles add up to give 90 degrees, the pair of angles are referred to as complementary angles. That is, they form a right angle.

The answer of the given question based on the circle is , Henry needs to purchase an additional 44 feet of fencing to enclose the new garden.

Circumference is distance around edge of  circular object. It is same as  perimeter of  circle. The circumference of a circle can be calculated using the radius of the circle, which is half the diameter.

The circumference of  circle with diameter d is given :

C = πd

Using the given diameter of 14 feet, the circumference of the original garden is:

C1 = πd1 = (22/7) * 14 = 44 feet

When the diameter is doubled to 28 feet, the circumference of the new garden is:

C2 = πd2 = (22/7) * 28 = 88 feet

To find how much more fencing Henry needs to purchase to enclose the new garden, we need to subtract the original circumference from the new circumference:

C2 - C1 = 88 - 44 = 44 feet

Therefore, Henry needs to purchase an additional 44 feet of fencing to enclose the new garden.

The exponential function that models a 15% decay is: y = (0.85)^t^(1/2)

To find the base that could be written in the blank to make the exponential function model a 15% decay, we can start by understanding the nature of exponential decay.

The general formula for exponential decay is given by:

y = A(1 - r)^t

Where:

y represents the final amount or value after time t.

A is the initial amount or value.

r is the decay rate (expressed as a decimal).

t is the time.

In this case, we want to find the decay rate (r) that corresponds to a 15% decay. A 15% decay means that the final amount is 85% of the initial amount. So, we can write the equation as:

y = A(1 - 0.15)^t

Simplifying further:

y = A(0.85)^t

Comparing this equation to the given form y = (_)t^(1/2), we see that the base in the blank must be 0.85.

Therefore, the exponential function that models a 15% decay is:

y = (0.85)^t^(1/2)

This equation represents a scenario where the initial value or amount (A) is being reduced by 15% over time (t), with the exponent of 1/2 indicating that the decay occurs at a square root rate.

Using the relation between velocity, distance and time, it is found that the velocity of the helicopter is of 225 mph and of the wind is of 69 mph.

Velocity is given by distance divided by time, that is:

\(v = \frac{d}{t}\)

A helicopter took 39 minutes to fly 191 miles, traveling in a headwind. Due to the headwind, the relative velocity is the sum of the velocities, hence:

\(v_h + v_w = \frac{191}{\frac{39}{60}}\)

\(v_h + v_w = 294\)

\(v_w = 294 - v_h\)

The same helicopter took one hour and 15 minutes to fly 195 miles flying in the opposite direction, hence:

\(v_h - v_w = \frac{195}{\frac{75}{60}}\)

\(v_h - v_w = 156\)

Since \(v_w = 294 - v_h\):

\(v_h - 294 + v_h = 156\)

\(2v_h = 450\)

\(v_h = 225\)

\(v_w = 294 - 225 = 69\)

Due to the difference in their price elasticity of demand, if a per-unit excise tax of the same amount is imposed on goods X and Y, the quantity demanded for good Y will decline more than the quantity demanded for good X.

1. Consider Good X with Price Elasticity of Demand (-0.5):

The demand for good X is inelastic if the price elasticity of demand is less than zero (-0.5).

This suggests that consumers are not particularly responsive to price changes and that changes in price do not considerably affect the quantity demanded.

Excise tax effects on good X:

When good X is subject to excise tax, its price will rise. The quantity demanded won't drastically decrease because the demand is inelastic.

2. Good Y with a (-2) demand price elasticity

Demand for good Y is elastic if price elasticity of demand is -2. This shows that consumers react quickly to price fluctuations and that the amount requested fluctuates considerably as well.

Excise tax effects on good Y:

Good Y's price will rise if the excise tax is applied. The quantity needed will significantly decrease since the demand is elastic.

The distance from the north most ship to the observation is 2.9 miles and the distance from the south most ship to the observation is 9.9 miles.

The bearing is defined as the angle measured clockwise from the north direction. A ship is anchored off a long straight shoreline that runs north and south.

From two observation points miles apart on shore, the bearings of the ship are 52 degrees and 134 degrees respectively. To find the distance from the ship to each of the observation points, we can use trigonometry.

Let's call the distance from the north observation point to the ship x, and the distance from the south observation point to the ship y. The bearings from the north and south observation points can be drawn as follows:

[asy]

unitsize(1cm);

pair O = (0,0), N = (-2,0), S = (2,0), A = (-2,1), B = (2,-1);

draw(O--N--A,Arrow);

draw(O--S--B,Arrow);

\(label("$52^\circ$", N + 0.3*dir(52), NE);\)

\(label("$134^\circ$", S + 0.3*dir(134), SE);\)

draw(O--A--B--cycle,dashed);

\(label("$x$", (N+A)/2, W);\)

\(label("$y$", (S+B)/2, E);\)

[/asy]

We can use the tangent function to find x and y, since we have the angle and opposite side.

From the north observation point, we have:

\($$\tan(52^\circ) = \frac{x}{2}$$$$x = 2\tan(52^\circ) \approx 2.95$$\)

From the south observation point, we have:

\($$\tan(134^\circ) = \frac{y}{2}$$$$y = 2\tan(134^\circ) \approx 9.88$$\)

Therefore, the distance from the north most ship to the observation is 2.9 miles and the distance from the south most ship to the observation is 9.9 miles.

Answer:

The hat was chosen was the child.

Step-by-step explanation:

Step-by-step explanation:

we have a right-angled triangle here.

there is the ground distance boat to lighthouse.

there is the height of the lighthouse = 141 ft.

and there is the line of sight boat to lighthouse light.

the angle at the boat is 12°.

the angle at the lighthouse bottom is 90°.

therefore, the angle at the lighthouse light is 180 - 90 - 12 = 78°

we use the law of sine to solve this.

a/sin(A) = b/sin(B) = c/sin(C)

with the sides and correlated angles being always opposite.

so, we have here

141/sin(12) = ground distance/sin(78)

ground distance = 141×sin(78)/sin(12) = 663.3528454... ft

≈ 663.35 ft

When x is equal to 1, the Function f(x) = -4x - 5 yields a value of -9.

The find ƒ(1) for the function f(x) = -4x - 5, we need to substitute x = 1 into the function and evaluate the expression.

Replacing x with 1, we have:

ƒ(1) = -4(1) - 5

Simplifying further:

ƒ(1) = -4 - 5

ƒ(1) = -9

Therefore, when x is equal to 1, the value of the function f(x) = -4x - 5 is ƒ(1) = -9.

Let's break down the steps taken to arrive at the solution:

1. Start with the function f(x) = -4x - 5.

2. Replace x with 1 in the function.

3. Evaluate the expression by performing the necessary operations.

4. Simplify the expression to obtain the final result.

In this case, substituting x = 1 into the function f(x) = -4x - 5 gives us ƒ(1) = -9 as the output.

It is essential to note that the notation ƒ(1) represents the value of the function ƒ(x) when x is equal to 1. It signifies evaluating the function at a specific input value, which, in this case, is 1.

Thus, when x is equal to 1, the function f(x) = -4x - 5 yields a value of -9.

The ordered pairs (-1, -6), (2, -18), (0, 0), and (-4, -12) do not correspond to the intervals where the graph of f(x) is decreasing. The pairs (1, -2) and (-3, -18) are the correct ones.

To determine where the graph of f(x) is decreasing, we need to examine the intervals where the function's derivative is negative. The derivative of f(x) is given by f'(x) = -3x^2 - 8x + 3.

Now, let's evaluate f'(x) for each of the given x-values:

f'(-1) = -3(-1)^2 - 8(-1) + 3 = -3 + 8 + 3 = 8

f'(2) = -3(2)^2 - 8(2) + 3 = -12 - 16 + 3 = -25

f'(0) = -3(0)^2 - 8(0) + 3 = 3

f'(1) = -3(1)^2 - 8(1) + 3 = -3 - 8 + 3 = -8

f'(-3) = -3(-3)^2 - 8(-3) + 3 = -27 + 24 + 3 = 0

f'(-4) = -3(-4)^2 - 8(-4) + 3 = -48 + 32 + 3 = -13

From the values above, we can determine the intervals where f(x) is decreasing:

f(x) is decreasing for x in the interval (-∞, -3).

f(x) is decreasing for x in the interval (1, 2).

Now let's check the ordered pairs in the table:

(-1, -6): Not in a decreasing interval.

(2, -18): Not in a decreasing interval.

(0, 0): Not in a decreasing interval.

(1, -2): In a decreasing interval.

(-3, -18): In a decreasing interval.

(-4, -12): Not in a decreasing interval.

Therefore, the ordered pairs (-1, -6), (2, -18), (0, 0), and (-4, -12) are not located in the intervals where the graph of f(x) is decreasing. The correct answer is: (1, -2), (-3, -18).
