Find the value or measure below. Assume that lines that appear tangent to be tangent.
Answers
Answer:
x = 11.2
Step-by-step explanation:
hypotenuse = 8.4 (radius) + 5.6 = 14
using the Pythagorean theorem:
x² = 14² - 8.4² = 196 - 70.56 =125.44
x = √125.44 = 11.2

Do 15^2 +10^2=c^2 than put answer Into \sqrt()
Step-by-step explanation:
Step-by-step explanation:
Ok, so the pythagorean theorem is a^2 + b^2 = c^
where c is the hypotenuse and b and a are the the other 2 sides
9) 10^2 + b^2 = 15^2
100 + b = 225
-100 -100
b^2 = 125
sqrt of 125 = 5
b = 5
10) 2^2 + 5^2 = C^2
4 + 25 = c^2
sqrt of 29 = c
c = [tex]\sqrt{29\\}[/tex]
11) 42^2 + a^2 = 48^2
1764 + a^2 =2304
-1764 -1764
a^2 = 540
a = [tex]6\sqrt{15}[/tex]

Which survey question is biased?

B. "Which meal-breakfast, lunch, or dinner-is your favorite meal of the day?"
C. “During which month do you prefer to go on vacation?"
D. “Do you prefer white bread or healthy, whole-wheat bread?”
Answers
Answer:
A.
Step-by-step explanation:
It was trick question because they all are opinionated, but the first one should be an easy yes or no question. However, if you do not like the president then you would say no because of bias. The rest are supposed to be "biased" because they are asking what you prefer.
"Should the President of the United States serve a six-year term?" is question is biased
What is Survey bias?Survey bias is a "systematic error introduced into sampling or testing by selecting or encouraging one outcome or answer over others." Due to this "encouragement" for a particular result, surveys may be biassed and only provide one type of consumer perspective.
For first, It presumes that the responder supports the idea that the President should hold office for a six-year term, which may not apply to all respondents.
However, out of bias, you would say "no" if you didn't like the president. The others are supposedly "biassed" since they inquire about your preferences.
Thus, the biased question is Should the President of the United States serve a six-year term?.

What is the equation of the sinusoid?
Will mark brainliest plz help
Answers
The general equation of the sinusoid is [tex]f(x)=sinx[/tex]
What is sinusoidal?"A sine wave or sinusoidal is a continuous or mathematical curve which is used to describe a smooth periodic oscillation."
We know,
A Sinusoidal function is a function that can be modelled using a sine wave.
The sine graph repeats itself after a period of 2π, which shows the function is periodic with a period of 2π.
f (x) = sin x and f (x) = cos x are similar apart from a phase shift, both functions are sinusoidal.
f (x) = tan x is a trigonometric function, but its graph is completely different.
The graph of a sinusoidal function is a smooth periodic graph.
The graph is continuous all over the x-axis and also it repeats itself after every fixed interval.
∵ A phase shift is the only difference between sine and cosine, any sinusoidal function that can be modelled using sine can also be modelled using cosine.
The general sinusoidal function is [tex]f(x)=[/tex]±[tex]a.sin(b(x+c))+d[/tex]
Where as,
± controls the reflection across the x - axis, coefficient a controls the amplitude , constant d controls the vertical shift, coefficient b controls the horizontal stretch.
∴ The general equation of the sinusoid is [tex]f(x)=sin x[/tex]

The true statement about the histogram are
(a) the median and the mean are approximately equal(d) the histogram would have an approximately normal curve(e) there are more data elements between 6 and 9.How to interpret the histogram?The dataset is given as:
5.5, 6, 7, 10, 7.5, 8, 9.5, 9, 8.5, 8, 7, 7.5, 6, 6.5, 5.5
Using a statistical calculator, we have the following summary:
Mean = 7.43
Median = 7.5
Notice that the median and the mean are approximately equal
i.e. 7.43 ≈ 7.5
When the mean and the median are equal, the histogram would have an approximately normal curve
Also, when the dataset is sorted, we have:
5.5, 5.5, 6, 6, 6.5, 7, 7, 7.5, 7.5, 8, 8, 8.5, 9, 9.5, 10
