What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The equation is,
x² - 2x + y - 4 = 0
Now, We can change it into vertex of this parabola as;
x² - 2x + y - 4 = 0
x² - 2x + 1 - 1 + y - 4 = 0
(x - 1)² + y - 5 = 0
(x - 1)² = - y + 5
(x - 1)² = - 1 (y - 5)
Thus, The vertex of the parabola is,
⇒ (1, 5)

What is the angle of elevation of the sun when a 44 ft mast casts a 13ft shadow?
Answer:
here
Step-by-step explanation:
Let the angle of elevation be \thetaθ
\begin{gathered} \therefore \tan \: \theta = \frac{height \: of \: mast}{height \: of \: shadow} \\ \\ \therefore \tan \: \theta = \frac{44}{14} \\ \\ \therefore \tan \: \theta = 3.14285714 \\ \\ \therefore \: \theta = {\tan}^{ - 1} (3.14285714) \\ \therefore \: \theta = 72.349875765 \degree \\ \\ \huge \red{ \boxed{\therefore \:\theta = 72.35 \degree}}\end{gathered}
∴tanθ=
heightofshadow
heightofmast
∴tanθ=

44
∴tanθ=3.14285714
∴θ=tan
−1
(3.14285714)
∴θ=72.349875765°
∴θ=72.35°
Hence, angle of elevation of the sun is 72.35°.

A company is going to make an oil container in the shape of a cylinder. As shown below, the container will have a height of 6m and a diameter of 6m. The container will be made from steel (including its top and bottom). If the steel costs $27 for each square meter, how much will the steel cost in total? If necessary, refer to the list of geometry formulas. For your calculations, do not round any intermediate steps, and use the π button on the ALEKS calculator. Round your answer to the nearest cent
Answer:
The cost of required steel is [tex]169.56 *27 = 4578.12[/tex] dollars
Step-by-step explanation:
The surface area of cylinder will be equivalent to the area of the steel sheet.
Surface area of cylinder [tex]= 2\pi rh+2\pi r^2[/tex]
Substituting the given values we get
Surface area of cylinder
[tex]= 2*3.14*3*6 + 2*3.14 *3^2\\= 169.56[/tex]square meter
Cost of 1 square meter of steel is $27
Then, the cost of required steel is
[tex]169.56 *27 = 4578.12[/tex] dollars
Round 2.261 to the nearest half.

G and H are mutually exclusive events. • P(G) = 0.5 • P(H) = 0.2
Answer:
[tex]P(G\ or\ H) = 0.7[/tex]
Step-by-step explanation:
Given
[tex]P(G) = 0.5[/tex]
[tex]P(H) = 0.2[/tex]
Required [Missing from the question]
[tex]P(G\ or\ H)[/tex]
Because the events are mutually exclusive, we use:
[tex]P(G\ or\ H) = P(G) + P(H)[/tex]
So, we have:
[tex]P(G\ or\ H) = 0.5 + 0.2[/tex]
[tex]P(G\ or\ H) = 0.7[/tex]

The number of baby carrots in a bag is normally distributed with a mean of 94 carrots and a standard deviation of 8.2 carrots.
Approximately what percent of the bags of baby carrots have between 90 and 100 carrots?
23.3%
31.2%
45.5%
76.73%
Answer:
46% is the percent of the bags of baby carrots that have between 90 and 100 carrots
Step-by-step explanation:
The baby carrot is normally distributed.
z = (x - µ)/σ
x is equal to number of baby carrots
µ = mean
σ = standard deviation
Substituting the given values, we get -
90 ≤ x ≤ 100
z = (90 - 94)/8.2 = - 0.49
For z value of -0.49, the probability is 0.31
For x = 100
z = (100 - 94)/8.2 = 0.73
For z value of 0.73, the probability is 0.77
P(90 ≤ x ≤ 100) = 0.77 - 0.31 = 0.46
The percent of the bags of baby carrots having carrots between 90 and 100 carrots is 0.46 × 100 = 46%

What is the probability that a randomly selected subprime mortgage in the state during November 2008 was not current? (Round your answer to two decimal places.)
Complete question is;
The attached chart shows the (approximate) total number of subprime home mortgages in a state in November 2008, broken down into four categories.
What is the probability that a randomly selected subprime mortgage in the state during November 2008 was not current? (Round your answer to two decimal places.)
Answer:
Probability that the one randomly selected was not current = 0.36
Step-by-step explanation:
From the attached image, we can see that the four mortgage categories are mutually exclusive. This means that none of the 4 status depends on any other.
From the image attached;
Total number of subprime mortgages = 196,280
Number of current mortgages = 126,330
Thus;
Probability of a randomly selected subprime mortgage being current = 126330/196280 = 0.64
Then;
Probability that the one randomly selected was not current = 1 - 0.64
Probability that the one randomly selected was not current = 0.36
