Which of the following best describes the triangle with the given measures?
OA. obtuse isosceles triangle
OB. acute equilateral triangle
OC. obtuse equilateral triangle
OD. acute isosceles triangle

Answer:

y = 2

Step-by-step explanation:

substitute x = [tex]\frac{4}{5}[/tex] ( = 0.8) into the formula

y = [tex]\frac{4}{0.8}[/tex] + [tex]\sqrt{0.8+0.2}[/tex] - 5(0.8)

 = 5 + [tex]\sqrt{1}[/tex] - 4

 = 5 + 1 - 4

 = 6 - 4

 = 2

Figure C shows only a line segment highlighted in red.

Figure C has four line segments connected to form a square, with the bottom line segment colored red.

The other three line segments in the figure are not colored, and only the bottom line segment is highlighted in red.

This means that only a line segment is shown in red, which is what the question is asking for.

Hence, figure C shows only a line segment highlighted in red.

The percentage of saline solution in brand B is 3%.

Let x be Percentage of saline solution in brand B

We know that the overall volume of saline solution in the combination is 18% of 6 gallons plus x% of (18 - 6) gallons since Danielle blended brands A and B to make a total of 18 gallons of 8% saline solution.

Then the equation is given as,

0.18(6) + 0.01x(18 - 6) = 0.08(18)

Simplifying and solving for x, we get:

1.08 + 0.12x = 1.44

0.12x = 0.36

x = 3

The approach employed in this specific instance is a non-probability sampling technique labeled as convenience sampling.

It involves selecting the participants based on convenience or, in other words, selecting those who are readily available to take part in the study. Hence the school district has decided to dispatch the survey to all parents whose children have access to the online questionnaire.

The selected sample principally arises from considerations of the ease with which it can be attained, thus making convenience rather than randomness the dominant factor informing the selection process.

The x and y values in the triangle are:

x = 58°

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°)

32 + 122 + y = 180

y = 180 - 32 - 122

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).

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.

We raise the fraction to the power of 4/3.

we can simplify each term within the parentheses before multiplying them together.

Let's simplify each term step by step:

\left( \frac{16}{9} \right)^{2/3}:

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}

\left( \frac{4}{3} \right)^{4/3}:

Similarly, we raise the fraction to the power of 4/3.

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

\left( \frac{9}{16} \right)^{2/3}:

We raise the fraction to the power of 2/3.

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

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.

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.
