C. 5/3 (5 sqrt 3) (8.66...)
Explanation:
You would use the SohCahToa to find out side x.
First, label your sides (10 is hypotenuse, x is the opposite, and blank side is the adjacent).
Second, figure out which part you have to use (Sin, Cosine, or Tangent). A good way to tell is of you have the missing side on top of the fraction, makes things easier.
Third, once you figure that out then plug stuff in...
Sin(theta) = O/H
Sin(60) = X/10
10sin(60) = X
8.66... = X

Answer:
Step-by-step explanation:
The Pythagorean theorem says:
[tex]a^2+b^2=c^2[/tex]
where a and b are the two legs of the triangle and c is the hypotenuse. Here, let's say a = 6 and b = [tex]\sqrt{13}[/tex]. We then get the following equation:
[tex]c^2= (6)^2+(\sqrt{13})^2=49[/tex]
So c = 7. Technically, c can also equal -7 since (-7)^2 = 49 as well but that does not apply here because a side length cannot be <0. So 7 is the answer.

Answer:
4.8 km is the answer.
Step-by-step explanation:
a = ?
b = 5 km
c = 7 km
According to the Pythagorean theorem,
a² + b² = c²
a² + 5² = 7²
a² + 25 = 49
a² = 49 - 25
a² = 24
a = 4.8989
Round to the nearest tenth,
a = 4.8 km

We want to find the zeros of this polynomial:
p(x) = 2x^3 – x^2 - 8x + 4
Plot all the zeros (z-intercepts) of the polynomial in the interactive graph.
Answers
Answer:
Step-by-step explanation:
The point is that any graphing calculator will work. We use Desmos on Brainly.
The graph below is your complete answer.
You can actually find the zeros by factoring
p(x) = x^2(2x - 1) - 4(2x - 1)
p(x) = (2x - 1) (x^2 - 4)
p(x) = (2x - 1) (x - 2)(x + 2)

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 4.6 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 26 engines and the mean pressure was 4.9 pounds/square inch with a variance of 0.81. A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Answers
Answer:
Decision Rule; Reject H₀ if t > 1.708
Step-by-step explanation:
Given the data in the question;
sample size n = 26
sample mean x' = 4.9
Variance = 0.81
standard deviation σ = √variance = √0.81 = 0.9
level of significance ∝ = 0.05
Claim;
Null hypothesis H₀ : μ = 4.6
Alternative hypothesis H₁ : μ > 4.6
Test Statistics;
Right tailed test
Now, decision rule for rejecting H₀;
degree of freedom df = n - 1 = 26 - 1 = 25
so, Right tailed test { > in H₁ }
Hence, Critical Value = [tex]t_{\alpha ,df[/tex] = [tex]t_{0.05, 25[/tex] = 1.708
Decision Rule; Reject H₀ if t > 1.708

(5.4582 ; 6.8618)
Step-by-step explanation:
Given the data:
6 10 2 6 3 3 3 6 6 6 6 5 8 9 10 10 7 9 3 6 5 10 9 9 10 3 8 6 6 3 3 6 6 5 4 10 9 3 5 7 10 6 3 8 6 8 3 3 5 5
Sample mean, xbar = Σx / n
n = sample size = 50
ΣX = 308
xbar = 308 / 50 = 6.16
Using a Calculator :
The sample standard deviation, s = 2.469
Confidence interval = xbar ± margin of error
Margin of Error = Tcritical * s/sqrt(n)
Tcritical at 95% ; df = 50 - 1 = 49
Tcritical = 2.010
Hence,
Margin of Error= 2.010 * (2.469/sqrt(50)) = 0.7018
Lower boundary : (6.16 - 0.7018) = 5.4582
Upper boundary : (6.16 + 0.7018) = 6.8618
