Applying the triangle sum theorem, the value of x in the image given is:

x = 33°;   x = 45°

Recall that according to the triangle sum theorem, all three interior angles of a triangle is equal to 180 degrees.

a. x + 21 + (180 - 54) = 180 [triangle sum theorem]

x + 147 = 180

x = 180 - 147

x = 33°

b. (180 - 102) + x + 57 = 180 [triangle sum theorem]

x + 135 = 180

x = 180 - 135

x = 45°

The function f(x)* = 1 + x^2 is defined for all real numbers x, so the domain is all real numbers, or (-∞, ∞).

In determining the function's output values, one must consider its collection of feasible results to extract the range. Reviewing f(x)* exhibits a minimum value of 1 due to x^2 being perpetually non-negative, while adding another factor merely preserves positivity.

Concurrently as x skyrockets, so too does the value of f(x)* given that approaching infinity generates infinitely larger powers than any constant coefficient subordinated by it. Consequently, the overall range of f(x)* becomes [1, ∞), enwrapping all feasible solutions equivalent or superior to 1.

Answer: 1/5

Step-by-step explanation:

In this case, you multiple the exponents together because you are raising a power to a power:

25^(-3/2 * 1/3)

25^(-3/6)

25^(-1/2)

Next, when the power is negative, we can get rid of it by changing the whole number to its reciprocal (divide the number by one):

1/(25^(1/2))

Now, when an exponent is a fraction, the numerator is what the base is raised to and the denominator is what the base is rooted to:

1/(sqrt(25))

Now, simplify:

The cost of one hour of television each day is $1.

We have,

The average electricity bill reduced to $130 to $40.

Number of days in month= 30 days

So, the cost of one hour of television is

Let x be the number of 16 oz jars of peanut butter collected, and y be the number of 28 oz jars of peanut butter collected.

The system of equations that represents the constraints in this situation is:

x + y = 82 (total number of jars collected)

16x + 28y = 1876 (total amount of peanut butter collected in ounces)

b. To solve for the number of 16 oz jars and 28 oz jars of peanut butter donated to the food bank

we need to solve the system of equations from part (a). One way to do this is to use elimination:

Multiplying the first equation by 16, we get:

10 times will the smaller gear turn.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Since the smaller gear has 10 teeth and the bigger gear 20, the smaller gear will turn twice for every rotation of the larger gear (20/10=2).

Therefore, if the larger gear rotates five times, the smaller gear will rotate two times five times, or ten times. The smaller gear will thus rotate 10 times.

So, if the bigger gear turns around 5 times, the smaller gear will turn around 5 x 2 = 10 times.

To simplify this term, we raise the fraction to the power of 2/3.

\left( \frac{16}{9} \right)^{2/3} = \left( \left( \frac{2^4}{3^2} \right)^{1/3} \right)^2 = \left( \frac{2^{4 \cdot 1}}{3^{2 \cdot 1}} \right)^2 = \left( \frac{2^4}{3^2} \right)^2 = \left( \frac{16}{9} \right)^2 = \frac{16^2}{9^2} = \frac{256}{81}

A polynomial function f(x) of degree 3 with given zeros, 2, -3 , 5 and condition f(3)=6 is given by f(x) = -1/2 (x-2)(x+3)(x-5).

Degree of the polynomial function is equal to 3.

Zero's of the polynomial function is equal to 2, -3 , 5 .

And f(3) = 6

If 2, -3, and 5 are zeros of f(x), then we can write function as,

f(x) = a(x-2)(x+3)(x-5)

where a is some constant.

To determine the value of a, we can use the fact that f(3) = 6.

Substituting x = 3 into the equation above, we get,

f(3) = a(3-2)(3+3)(3-5)

     = -12a

Here we have,

f(3) = 6, so we can set these two expressions equal to each other and solve for a,

⇒ -12a = 6

⇒ a = -1/2

Now we can substitute this value of a back into the equation for f(x) that we found earlier,

⇒ f(x) = -1/2 (x-2)(x+3)(x-5)

Therefore, a polynomial function f(x) of degree 3 with zeros 2, -3, 5, and f(3) = 6 is equal to f(x) = -1/2 (x-2)(x+3)(x-5).

y = 26°

Trigonometry deals with the relationship between the ratios of the sides of a triangle with its angles.

To find the x and y values in the triangle, check the attached image for labeling.

In the image:

Triangle ABC is isosceles. Thus,

t = 61° (base angles of isosceles triangles are equal)

x + t + 61 = 180  (sum of angles in a triangle is 180°)

x + 61 + 61 = 180

x = 180 - 61 - 61

x = 58°

x + v = 180 (sum of angles on a straight line is 180°)

58 + v = 180

v = 180 - 58

v = 122°

In triangle ACD:

32 + v + y = 180  (sum of angles in a triangle is 180°)

To find the variability in the distribution of the means, we need to calculate a measure of spread, such as the standard deviation. We can use the dot plot to estimate the standard deviation of the distribution.

From the dot plot, we see that the range of the means is from 0 to 150 bags of dog food sold per day. The midpoint of this range is 75, which we can use as an estimate of the population median. We can estimate the standard deviation by calculating the distance between the median and the quartiles.

From the dot plot, we can see that the lower quartile (Q1) is around 60, and the upper quartile (Q3) is around 110. Therefore, the interquartile range (IQR) is:

IQR = Q3 - Q1 = 110 - 60 = 50

We can use the IQR to estimate the standard deviation by assuming that the distribution is approximately normal and using the empirical rule, which states that:

Approximately 68% of the data falls within one standard deviation of the mean.

Approximately 95% of the data falls within two standard deviations of the mean.

Approximately 99.7% of the data falls within three standard deviations of the mean.

Since the IQR is about half of the range, we can estimate the standard deviation as:

SD ≈ IQR / 1.35 ≈ 50 / 1.35 ≈ 37

Therefore, an appropriate estimate of the standard deviation of the distribution of means is 37, rounded to the nearest whole number.

Interpretation: The variability in the distribution of means is relatively large, with a standard deviation of approximately 37 bags of dog food sold per day. This means that the mean number of bags sold per day can vary by as much as 37 bags from one sample to another.
