A 15ft. wire is tied to the top of a tree to provide support. If the wire forms a 25° angle with the ground, what is the height of the tree to the nearest hundredth?
Answers
Answer: [tex]6.34\ ft[/tex]
Step-by-step explanation:
Given
The length of the wire is [tex]l=15\ ft[/tex]
The Wire makes an angle of [tex]25^{\circ}[/tex] with horizontal
Suppose the height of the tree is h
From the figure, we can write
[tex]\Rightarrow \sin 25^{\circ}=\dfrac{h}{l}\\\\\Rightarrow h=l\sin 25^{\circ}\\\Rightarrow h=15\sin 25^{\circ}\\\Rightarrow h=6.34\ ft[/tex]
Thus, the height of the tree is [tex]6.34\ ft[/tex]

State whether f^-1 (x) is a function given the equation
Answers
Answer:
We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.
Step-by-step explanation:
Existence of an inverse function:
An inverse function will exist if: f(a) = f(b) only if a = b.
In this question:
[tex]f(a) = -\frac{1}{7}\sqrt{16 - a^2}[/tex]
[tex]f(b) = -\frac{1}{7}\sqrt{16 - b^2}[/tex]
[tex]-\frac{1}{7}\sqrt{16 - a^2} =-\frac{1}{7}\sqrt{16 - b^2}[/tex]
[tex]\sqrt{16 - a^2} = \sqrt{16 - b^2}[/tex]
[tex](\sqrt{16 - a^2})^2 = (\sqrt{16 - b^2})^2[/tex]
[tex]16 - a^2 = 16 - b^2[/tex]
[tex]a^2 = b^2[/tex]
[tex]a = \pm b[/tex]
We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.
Rhombus CDEF is shown below. If the slope

Answers
Answer:
15
Step-by-step explanation:

The slope of side CD in rhombus CDEF is -2/5. Therefore, option B is the correct answer.
What is a rhombus?A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square.
Given that, the rhombus is CDEF and the slope of FC is 5/2.
Here, sides FC and CD are perpendicular.
The slope of a line perpendicular to given line is m₁=-1/m₂
Slope of CD is -2/5.
Therefore, option B is the correct answer.

In order to determine the average commute of college students, a researcher gathers data from a group of 50 students at the local college. This sample yieldied a mean of 14 and a standard deviation of 1.9.
Required:
Construct a 90% confidence interval for the population mean from the provided data.
Answers
Answer:
13.5579875<x<14.44201244
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as:
CI = x+/- z × s/\sqrt{n}
x us the mean = 14
Z is the 90% CI = 1.645
S is the standard deviation = 1.9
n is the sample size = 50
Substitute.
CI = 14+/-1.645×1.9/7.07106.
CI = 14+/-1.645×0.26870057
CI = (14-0.44201244, 14+0.44201244)
CI = 13.5579875, 14.44201244
Hence the required interval is 13.5579875<x<14.44201244

The PRIDE club is selling school t-shirts and hoodies during football games. Two t-shirts and 2
hoodies will sell for $76.50. Five t-shirts and 3 hoodies will sell for $140.25. How much does
each shirt sell for?
Answers
Answer:
Cost of each hoodies = $25.5
Cost of each t-shirt = $12.75
Step-by-step explanation:
Given:
Cost of 2 t-shirt and 2 hoodies = $76.50
Cost of 5 t-shirt and 3 hoodies = $140.25
Find:
Cost of each t-shirt
Computation:
Assume;
Cost of each t-shirt = t
Cost of each hoodies = h
So,
2t + 2h = 76.50..........eq1
5t + 3h = 140.25..........eq2
Eq 1 x 2.5
5t + 5h = 191.25.............eq3
Eq3 - Eq2
2h = 51
h = 25.5
Cost of each hoodies = $25.5
2t + 2h = 76.50
2t + 2(25.5) = 76.50
t = 12.75
Cost of each t-shirt = $12.75

Range = 60
Min Value = 5
Max value = 65
Mean = 42.31
Variance =100.00
Standard deviation = 10.00
Sum = 1,227
Answers
Answer:
[tex]t = 7.359[/tex]
Step-by-step explanation:
Given
[tex]Range = 60[/tex]
[tex]Min = 5[/tex]
[tex]Max = 65[/tex]
[tex]\bar x = 42.31[/tex]
[tex]\sigma^2 =100.00[/tex]
[tex]\sigma = 10.00[/tex]
[tex]\sum = 1227[/tex]
[tex]n=40[/tex]
Required
The t statistic
This is calculated using:
[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]
Where
[tex]\mu \to[/tex] Population mean
[tex]\mu = \frac{\sum }{n}[/tex]
[tex]\sum = 1227[/tex] and [tex]n=40[/tex]
[tex]\mu = \frac{1227}{40}[/tex]
[tex]\mu = 30.675[/tex]
So, we have:
[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]
[tex]t = \frac{42.31 - 30.675}{10/\sqrt{40}}[/tex]
[tex]t = \frac{42.31 - 30.675}{10/6.325}[/tex]
[tex]t = \frac{11.635}{1.581}[/tex]
[tex]t = 7.359[/tex]
