The attraction which reaches a greater height with what it represent in terms of the context are:

  • The slingshot reaches a greater height at 162 feet, which is the vertex of the parabola.
  • The Ferris wheel reaches a greater height at 145 feet, which is the highest point on the circle.

<h3>What is the equation of a circle?</h3>

Mathematically, the standard form of the equation of a circle is represented by this mathematical expression;

(x - h)² + (y - k)² = r²     ......equation 1.

Where:

  • h and k represents the coordinates at the center.
  • r represents the radius of a circle.

From the question, we have the following information:

(x – 100)² + (y – 75)² = 4,900    .....equation 2.

By comparing equation 1 and equation 2, we have the following parameters:

Center of circle, (h, k) = (100, 75) feet.

Radius, r = √4,900 = 70 feet.

Therefore, the height of the highest point on this circle is given by:

Highest point = r + k

Highest point = 70 + 75

Highest point = 145 feet.

For the slingshot, we have:

y = –3x² + 48x – 30.

The vertex of a parabola occurs when x = -b/2a;

x = -48/2(-3)

x = 48/6

x = 8.

When x = 8, the vertex of this parabola is given by:

y max = –3x² + 48x – 30.

y max = –3(8)² + 48(8) – 30.

y max = -192 + 384 - 30

y max = 162 feet.

Quick algebra 1 question for 10 points!
zaharov [31]

<u>Answer:</u>

○ x = -7

<u>Step-by-step explanation:</u>

Given the equation:

10(x + 10) - 4 = 11 - 5(2x + 11),

to solve for x, we have to rearrange the equation to make x its subject.

10(x + 10) - 4 = 11 - 5(2x + 11)

⇒ 10x + 100 - 4 = 11 - 10x -55      [expand brackets]

⇒ 10x + 96 = -44 - 10x

⇒ 10x + 10x + 96 = -44                   [add 10x to both sides]

⇒ 20x + 96 = -44

⇒ 20x = -44 - 96                             [subtract 96 from both sides]

⇒ 20x = -140

⇒ x = \frac{-140}{20}                                        [divide both sides by 20]

⇒ x = \bf-7

The concentration C (in mg/dl), of a certain antibiotic in a patient's bloodstream is given by C(t)=50 t /(t^2 + 25) where t is
marishachu [46]
Given that the concentration has been modeled by the formula:
C(t)=50t/(t^2+25)
where:
t is time in hours.
The concentration after 5 hours will be given by:
t= 5 hours 
plugging the value in the equation we get:
C(5)=(50(5))/(5^2+25)
simplifying the above we get:
C(5)=250/(50)=5 mg/dl

Answer: 5 mg/dl
