The coordinate of the vertex of the parabola y - 4 = 2(x+7)² is (-7,4)
The coordinate of the vertex?The equation of the parabola is given as:
y - 4 = 2(x+7)²
Add 4 to both sides
y = 2(x+7)² + 4
A parabola is represented as:
y = a(x- h)² + k
Where, the vertex is:
vertex = (h,k)
By comparison, we have:
Vertex = (-7,4)
Hence, the coordinate of the vertex is (-7,4)

Describe how to optimize a function given a set of constraints.
The setup for this problem is written as l(x,y)= f(x,y)+λg(x,y)
For example, a common economic problem is the consumer choice decision. Households are selecting consumption of various goods. However, consumers are not allowed to spend more than their income (otherwise they would buy infinite amounts of everything!!). Let’s set up the consumer’s problem:
Suppose that consumers are choosing between Apples (A) and Bananas (B). We have a utility function that describes levels of utility for every combination of Apples and Bananas.
11
A 2 B 2 = Well being from consuming (A) Apples and (B) Bananas.
Next, we need a set of prices. Suppose that Apples cost $4 apiece and Bananas cost $2 apiece. Further, assume that this consumer has $120 available to spend. The income constraint is
$2B+$4A≤$120
However, the problem requires that the constraint is in the form g(x, y)≥ 0. In
the above expression, subtract $2B and $4A from both sides. Now we have 0≤$120−$2B−$4A
g(A, B) Now, we can write out the lagrangian
11
l(A,B)= A2 B2 +λ(120−2B−4A)
f (A, B) g(A, B)
Step II: Take the partial derivative with respect to each variable We have a function of two variables that we wish to maximize.
Therefore, there will be two first-order conditions (two partial derivatives that are set equal to zero).

Answer:
0.8224
Step-by-step explanation:
Data
mean: $76standard deviation, sd: $10first value of interest, x1: $63second value of interest, x2: $90z-score for x1:
z1 = (x1 - mean)/sd = (63 - 76)/10 = -1.3
z-score for x2:
z2 = (x2 - mean)/sd = (90 - 76)/10 = 1.4
The proportion of wrist watch prices are between $63 and $90 is:
P(z1 < z < z2) = P(z < 1.4) - P(z < -1.3)
P(z < 1.4) = 0.9192 (see first picture attached)
P(z < -1.3) = 0.0968 (see second picture attached)
P(z1 < z < z2) = 0.9192 - 0.0968 = 0.8224
The sector has an area of 3 pi inches squared and a radius of 6 in. How many inches long is the arc for this sector? Use 3.14 for Pi and round to the nearest hundredth.
A sector with a radius of 6 inches and area of 3 pi inches squared.
Recall that Area of a sector = StartFraction n degrees over 360 degrees EndFraction (pi) (r squared) and StartFraction Arc length over Circumference EndFraction = StartFraction n degrees over 360 degrees EndFraction.
3.14
6.28
12.56
18.84
Answer: 6.28 inches.
Step-by-step explanation:
Formula :
i) Area of sector : [tex]A=\dfrac{x}{360}\times\pi r^2,[/tex], where x = central angle and r is radius
ii) Length of arc : [tex]l=\dfrac{x}{360}\times2\pi r[/tex]
Given , r= 6 in.
A = [tex]3\pi[/tex] inches
Put these values in (i) , we get
[tex]3\pi =\dfrac{x}{360}\times\pi (3)^2\\\\\Rightarrow\ 1=\dfrac{x}{120}\\\\\Rightarrow\ x=120^{\circ}[/tex]
Now , put values of x and r in (ii) , we get
[tex]l=\dfrac{120}{360}\times2\pi(3)\\\\\Rightarrow\ l=2\pi = 2(3.14)=6.28\text{ inches}[/tex]
Hence, the length of the arc is 6.28 inches.

A catapult launches a boulder with an upward velocity of 120 ft/s. The height of the boulder, h, in feet after t seconds is given by the function h = -16t^2 + 120t + 10. How long does it take to reach maximum height? What is the boulder's maximum height? What is the boulder's maximum height? Round to the nearest hundredth, if necessary.
Answer:
See below in bold.
Step-by-step explanation:
h = -16t^2 + 120t + 10
To find the height and time for maximum we convert to vertex form:
h = -16(t^2 - 7.5t) + 10
h = -16 [(t - 3.75)^2 - 14.0625] + 10
h = -16(t - 3.75)^2 + 225 + 10
h = -16(t - 3.75)^2 + 235
So the time to reach maximum height is 3.75 seconds and the maximum height = 235 ft.

A = 1/2 bh where b is the base and h is the height
30 = 1/2 (10) h
30 = 5h
Divide each side by 5
30/5 = 5h/5
6 = h

The diagram shows a circle centre O work out the size of angle X work out the size of angle y
Answer:
x = 116° , y = 20°
Step-by-step explanation:
The angles are x = 116° & y = 20°
what is the circle theorem?When two angles are subtended by the same arc, the angle at the centre of a circle is twice the angle at the circumference i.e ∠O=2∠A
let the Points on the circumference be A,B,C then we have two traingles namely ΔABC & ΔOBC.
Given here ∠A=58°
therefore, by the circle theorem we get ∠O=116°
Again in ΔOBC it is a isosceles triangle with its two sides equal to the radius of the circle, so ∠OBC = ∠OCB
∠OCB +∠OBC+∠BOC=180°
2 ∠OBC=180°-116°
2 ∠OBC=64°
∠OBC=32°
Again, in ΔABC ∠C = 32° + 38° = 70° & ∠B= y +32°
therefore, y + 32° + 70° + 58° = 180°
y= 20°
Hence, the angles are x = 116° & y = 20°
