As per the question, the solution to the equation f(x) = a(x-h)2+k is y = 3(x+5)2 -1.
What is an equation?Equations are mathematical expressions with two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be similar to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a simple fundamental equation.
As per the given values mentioned in the question,
a=3, b=30, c=74.
To fix this issue, employ the Vertex Formula,
(-b/(2a)) , f(-b/(2a))
-b/(2a)
= -(30)/(2 × 3)
h = -5.
f(-b/(2a))
= 3(-5)² + 30(-5) + 74

What is tangent?
The straight line that "just touches" the curve at a given point is referred to as the tangent line to a plane curve in geometry. It was defined by Leibniz as the path connecting two points on a curve that are infinitely close together.
Given:
Graph is a parabola tangent to the x-axis at (4,0) with y-intercept 6.
That is there are two points (4, 0) and (0, 6).
From these two points we have to find the slope of the line.
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{0-6}{4-0} = -\frac{6}{4} = -\frac{3}{2}[/tex]
Now to use point slope form of the line.
[tex]y-y_1 = m(x-x_1)\\ y - 6 = -\frac{3}{2}(x-0)\\ y - 6 = -\frac{3}{2}x\\ y = -\frac{3}{2}x + 6[/tex]
Hence, the equation of line is, [tex]y = -\frac{3}{2}x + 6[/tex].

A town has a population of 17000 and grows at 3% every year. What will be the

Answers
If the population grows 3% every year, then each year's population is 103% of the previous year's population. This gives us the exponential function:

17000 for the current population, 1.03 growth factor for the 103%, raised to the x power because we'll need 103% of 103% of 103% and so on until we multiply by 103% for the correct number of years.

Michael went shopping for a new video game because of a sale. The price on the tag was $46, but Michael paid $34.50 before tax. Find the percent discount.
Answers
The discount percentage offered on the new video game as of a sale is 75%.
Explain the term discount percentage?When a product is offered at a discount, the seller is reducing the product's price from what it was originally listed for. The percentage discount just on product is determined by the discount amount stated as a percentage of the initial price.For the stated question-
The listed price on the video game = $46.
price paid exclusive of tax = $34.50.
Let 'x' be the percentage discount of the listed price.
Then,
x% of 46 = 34.50
x = 34.50 x 100 / 46
x = 75%
Thus, the discount percentage offered on the new video game as of a sale is 75%.

Answers
The wire used for the triangular pendant can have a cost more than 664.65 USD and less than 791.25 USD.
How to determine the possible lengths of the missing side
In this problem we find the case of a triangle, in which the length of two sides are known and we need to determine the range of costs associated to the set of all possible triangles. This can be derived by the geometric system described in the image attached below. The minimum and the maximum costs of the pendant:
θ = 0°
l = 10.5 cm - 2.5 cm
l = 8 cm
s = 10.5 cm + 8 cm + 2.5 cm
s = 21 cm
C = (31.65 USD / cm) · (21 cm)
C = 664.65 USD
θ = 180°
l = 10.5 cm + 2.5 cm
l = 13 cm
s = 10.5 cm + 2.5 cm + 12.5 cm
s = 25 cm
C = (31.65 USD / cm) · (25 cm)
C = 791.25 USD

Supplementary angles are angles that have a sum of 180 degrees. They are formed on a straight line.
Solving the QuestionLooking at the given diagram, we can notice how angle SUV and SUT are supplementary angles. We know this because they form the straight line, VT.
We are given angle SUT, which is 58 degrees.
Because angles SUV and SUT have a sum of 180 degrees, we can solve for angle SUV by subtracting 58 from 180:
180 - 58 = 122
Therefore, angle SUV is 122 degrees.
Answer122 degrees

Angle SUV = 180 - 58
