Answer:
y=-2x+8
Step-by-step explanation:
So I select 2 points:
(0,8) and (4,0)
so then I find the slope.
m = [tex]\frac{8-0}{0-4} \\=\frac{8}{-4} \\=\frac{2}{-1} \\=-2[/tex]
m = -2
Then the b (y-intercept) is 8, so equation is:
y=-2x+8

Eliminate the parameter. x = t^2 + 1, y = t^2 - 1.
Answers
Answer:
Eliminating the parameter, the equation is [tex]y = x - 2[/tex]
Step-by-step explanation:
We are given the following parametric equations:
[tex]x = t^2 + 1[/tex]
[tex]y = t^2 - 1[/tex]
We want to eliminate the parameter t. From the first equation:
[tex]x = t^2 + 1[/tex]
[tex]t^2 = x - 1[/tex]
Replacing in the second equation:
[tex]y = x - 1 - 1[/tex]
[tex]y = x - 2[/tex]
Eliminating the parameter, the equation is [tex]y = x - 2[/tex]

Answers
Use the squeeze theorem; if
1 - x ²/4 ≤ u(x) ≤ 1 + x ²/2,
then taking the limit on each part as x approaches 0 gives
1 ≤ lim [x → 0] u(x) ≤ 1
and so the limit of u(x) as x → 0 is simply 1.

The company wishes to test Upper H Subscript 0 Baseline colon mu equals 175 millimeters versus Upper H Subscript 1 Baseline colon mu greater-than 175 millimeters, using the results of n equals 4 samples. Calculate the P-value if the observed statistic is
Answers
Answer:
The p-value of the observed statistic is 0.15866
Step-by-step explanation:
The given parameters of the system are;
The standard deviation of the foam height, σ = 20 mm
The null hypothesis, H₀; μ = 175 mm
The alternative hypothesis, Hₐ; μ > 175 mm
The number of observations that make the sample, n = 4
The observed statistic, [tex]\overline x[/tex] = 185
The test statistic is given as follows;
[tex]Z=\dfrac{\bar{x}-\mu }{\dfrac{\sigma}{\sqrt{n}}}[/tex]
Therefore, we get;
[tex]Z=\dfrac{185-175 }{\dfrac{20}{\sqrt{4}}} = 1[/tex]
P(Z > 1) = 1 - P(Z < 1) = 1 - 0.84134 = 0.15866
The p-value of the observed statistic = 0.15866

We are going to find the equation that satisfy the question.
The equation of a line is: [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.
The problem gives us the slope and a point the line passes through.
In order to find b, we plug in the given point (2,4) and solve.
[tex]4=\frac{3}{2} *2+b[/tex]
[tex]4=3+b\\1=b\\[/tex]
The equation for the line is:
[tex]y=\frac{3}{2} x+1[/tex]
By plugging in the points to see if it is true, we get that only (0,1) and (4,7) are on the line.

Solve x2 – 2x = 15 by applying the quadratic formula.
Answers
Using the quadratic formula, the value of x in the given situation is x = 4 ± √2+60x/2x.
What is the quadratic formula?The quadratic formula in elementary algebra is a formula that yields the answer to a quadratic problem.
In addition to the quadratic formula, other methods of solving quadratic equations include factoring, completing the square, graphing, and others.
A second-order equation of the form ax² + bx + c = 0 denotes a quadratic equation, where a, b, and c are real number coefficients and a 0.
We have:
x² – 2x = 15
x² – 2x - 15 = 0
The formula is:
x = -b ± √b² - 4ac/2a
Now, insert values as follows:
x = -b ± √b² - 4ac/2a
x = -(-2) ± √(-2)² - 4(x)(-15)/2x
x = 4 ± √2+60x/2x
Therefore, using the quadratic formula, the value of x in the given situation is x = 4 ± √2+60x/2x.
