Answer:
2. x ≈ 17.74
3. x ≈ 16.64
Step-by-step explanation:
The tangent function relates an angle to the opposite and adjacent sides of a right triangle:
Tan = Opposite/Adjacent
Here, we're looking for the measure of the side opposite the angle, so we can rearrange this relation to ...
Opposite = Adjacent×Tan
__
2. x = 32×tan(29°) ≈ 17.74
3. x = 13×tan(52°) ≈ 16.64

The polynomial p(x)=3x^3-20x^2+37x-20 has a known factor of (x-4). Rewrite p(x) as a product of linear factors. p(x) =
Answer:
[tex]p(x) = (x-4)(x - \frac{5}{3})(x - 1)[/tex]
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
In this question:
We have the polynomial [tex]p(x) = 3x^3-20x^2+37x-20[/tex]
It has a known factor [tex]x - 4[/tex]. This means that the polynomial can be written as:
[tex]p(x) = (x-4)q(x)[/tex]
In which q(x) is a second order polynomial, because p is of the third degree and q is of the first degree(3 - 1 = 2). So
[tex]q(x) = ax^2 + bx + c[/tex]
We have to find a, b and c. Then
[tex]3x^3-20x^2+37x-20 = (x-4)(ax^2 + bx + c)[/tex]
[tex]3x^3-20x^2+37x-20 = = ax^3 + (-4a + b)x^2 + (c - 4b)x - 4c[/tex]
Comparing both sides, we have that
[tex]a = 3[/tex]
[tex]-4c = -20 \rightarrow c = 5[/tex]
[tex]c - 4b = 37[/tex]
[tex]-4b = 32 \rightarrow b = -8[/tex]
Now we find the roots of this polynomial.
[tex]\bigtriangleup = b^{2} - 4ac = (-8)^2 - 4(3)(5) = 64 - 60 = 4[/tex]
[tex]x_{1} = \frac{-(-8) + \sqrt{4}}{2*3} = \frac{5}{3}[/tex]
[tex]x_{2} = \frac{-(-8) - \sqrt{4}}{2*3} = 1[/tex]
So, as a product of it's factors, we have that q is:
[tex]q(x) = (x - \frac{5}{3})(x - 1)[/tex]
And p(x)
[tex]p(x) = (x-4)q(x)[/tex]
[tex]p(x) = (x-4)(x - \frac{5}{3})(x - 1)[/tex]

A random sample of 11 nursing students from Group 1 resulted in a mean score of 65 with a standard deviation of 4.7. A random sample of 16 nursing students from Group 2 resulted in a mean score of 74 with a standard deviation of 2.5. Can you conclude that the mean score for Group 1 is significantly lower than the mean score for Group 2
Answer:
The calculated value of t= -1.118860 does not lie in the critical region t= -1.714 or t= -2.5. Therefore we accept our null hypothesis that the mean score for Group 1 is significantly lower than the mean score for Group 2 for both significance level of 0.05 and 0.01
Step-by-step explanation:
Groups Sample Size Mean Standard Deviation
1 11 65 4.7
2 16 74 2.5
Formulate null and alternate hypotheses as
H0 : u1 < u2 against Ha: u1 ≥ u 2
That is the mean of the group 1 is lower than the mean of the group 2
Degrees of freedom is calculated df = υ= n1+n2- 2= 11+16-2= 23
The significance level alpha is chosen to be ∝ = 0.05
The critical region t ≤ -t (0.05, 23) = -1.714
And if we choose alpha = 0.01 the critical region would be
t ≤ -t (0.05, 23) = -2.5
Here the difference between the sample means is x`1- x`2= 65-74= -9
The pooled estimate for the common variance σ² is
Sp² = 1/n1+n2 -2 [ ∑ (x1i - x1`)² + ∑ (x2j - x`2)²]
= 1/11+16-2 [ (65)²+(74)²]
= 1/23[ 4225+5476]
= 1/23[9701]
=421.782
Sp =√ 421.782=20.5373
The test statistic is
t = (x`1- x` ) /. Sp √1/n1 + 1/n2
t= -9/ 20.5373√1/11+ 1/16
t= -9/8.0439
t= -1.118860
The calculated value of t= -1.118860 does not lie in the critical region t= -1.714 or t= -2.5. Therefore we accept our null hypothesis that the mean score for Group 1 is significantly lower than the mean score for Group 2 for both significance level of 0.05 and 0.01

find the distance between the pionts(-5,1) and (4,1)
Explanation:
The formula for calculating the distance between two points is: d = √ ( x 2 − x 1 ) 2 + ( y 2 -y 1 ) 2 Substituting the points from the problem gives: d = √ ( 0 − 5 ) 2 + ( 4 − 1 ) 2 d = √ ( − 5 ) 2 + ( 3 ) 2 d = √ 25 9 d = √ 34 Or d =3 5.8 rounded to the nearest hundredth.
A swimming pool has a leak and is losing 23.5 gallons of water every 5 days. What is the average change in water volume each day?
Step-by-step explanation:
If you divide the distance by the elapsed time, the result will be the rate of water loss (evaporation). To convert this evaporation rate in to gallons lost over a specific time period, you will need convert the measure into a volume. WTG GLAD U GOT IT RIGHT..
please hurry i need an answer
Answer:
[tex]-\frac{11}{6}\ \frac{inches}{second}[/tex]
Step-by-step explanation:
Rate of Change
The average velocity is defined as the rate of change of the distance with respect to time. The table shows the distances of an object as a function of time.
It's required to find the average velocity between 8 s and 20 s.
The rate of change can be approximated as the slope between two points. We take from the table the points (8,32) and (20,10) and calculate the slope.
The slope can be calculated with the equation:
[tex]\displaystyle v=\frac{d_2-d_1}{t_2-t_1}[/tex]
[tex]\displaystyle v=\frac{10-32}{20-8}=\frac{-22}{12}[/tex]
Simplifying:
[tex]\displaystyle v=-\frac{11}{6}[/tex]
Choice: B. [tex]\mathbf{-\frac{11}{6}\ \frac{inches}{second}}[/tex]
Stefan sells Jin a bicycle for $137 and a helmet for $17. The total cost for Jin is 140% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make bying the bicycle and helmet to Jin? Stefan originally spent $
Answer:
Stefan originally spent $110.
Stefan made a profit of $44.
Step-by-step explanation:
Given that:
Stefan sold the bike and helmet for $137 and $17
Total amount = 137+17 = $154
This is 140% of the price Stefan originally paid.
Let,
x be the original price paid by Stefan
140% of x = $154
[tex]\frac{140}{100}x=154\\1.4x = 154\\\frac{1.4x}{1.4}=\frac{154}{1.4}\\x=110[/tex]
Therefore,
Stefan originally paid $110 for the bicycle and helmet.
Profit made by Stefan = 154-110 = $44
Hence,
Stefan originally spent $110.
Stefan made a profit of $44.

Q5. Asif is 5 years younger than Qasim. Four years later, Qasim will be twice as old as
Asif. Find their present ages.
Answer:
Age of Qasim = 6 year
Age of Asif = 1 year
Step-by-step explanation:
Let :
Age of Qasim = x
Age of Asif = x -5
After 4 years there age will be:
Age of Qasim = x+4
Age of Asif = x-5+4 = x-1
We are given: Four years later, Qasim will be twice as old as Asif.
Age of Qasim = 2 (Age of Asif)
x+4=2(x-1)
x+4=2x-2
2x-x=4+2
x=6
So, We get x = 6
The present ages will be:
Age of Qasim = x = 6 year
Age of Asif = x -5 = 6-5 = 1 year
