The required radius and error in radius is 13.8 cm and ± 0.12cm

Given that,
A machinist is required to manufacture a circular metal disk with an area of 600cm².
(a) What radius produces such a disk is to be determined
(b) If the machinist is allowed an error tolerance of ±5cm2 in the area of the disk, how close to the ideal radius in part is to be determined.

The area of a circle is given by the pie times square of the radius.

Area of circle = πr^2

Here,
a) The given area of disk = 600 cm²
   πr² = 600
   r = √600/3.14
   r = 13.8 cm

b) an error tolerance of ± 5 cm² in the area of the disk,
So the percentage of error is 0.84%
Now, 0.84% of radius = 0.84 *13.8/100 = 0.12
The required error in radius will be ±0.12 cm

Similarly,
c) limx→a f(x) = L
Where a is the area of the disk and L is length, and f(x) is function of area.

Thus, the required radius and error in radius is 13.8 cm and ± 0.12cm.

Answer:

The equation in slope-intercept form is: [tex]y=5x+32[/tex]

Step-by-step explanation:

To calculate the slope, [tex]m[/tex], we use the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1} }[/tex] where [tex]y[/tex] are the [tex]y[/tex]-values of the points and [tex]x[/tex] are the [tex]x[/tex]-values.

Pugging our numbers into the formula, we get [tex]\frac{(-3)-12}{-7-(-4)}[/tex]. This simplifies to 5.

To calculate the [tex]y[/tex]-intercept, we first substitute one of our points into the formula. Substituting -4  and 12, we get [tex]12=5(-4)+b[/tex].

Then we can solve for [tex]b[/tex].

[tex]12=5(-4)+b[/tex]

[tex]12=-20+b[/tex]

[tex]32=b[/tex]

So, our slope is 32.

We can then plug these values into the slope-intercept form [tex]y=mx+b[/tex]

Part A  The quadratic expression in factored form is 2t(19 - 8t)

Part B The height of the soccer ball 1.25 seconds after Callie kicks it is 22.5 ft

Since Callie kicks a soccer ball from the ground. The height of the ball, in feet, above the ground t seconds after the ball is kicked can be represented by the expression 38t- 16t².

So, the expression is a quadratic expression, we have that h(t) = 38t- 16t².

To write the expression in factored form, we find the common factors of both terms and factor them out.

So,  h(t) = 38t- 16t²

= 2 × 19 × t - 2 × 8 × t × t

Factoring out 2 and t, we have

= 2 × t × (19 - 8 × t)

= 2t(19 - 8t)

So, the quadratic expression in factored form is 2t(19 - 8t)

Since the quadratic expression h(t) = 38t- 16t² represents the height of the ball above the ground in feet, to find the height of the ball after 1.25 second,we substitute t = 1.25 s into the expression.

So, h(t) = 38t- 16t²

h(1.25) = 38(1.25) - 16(1.25)²

h(1.25) = 47.5 - 16(1.5625)

h(1.25) = 47.5 - 25

h(1.25) = 22.5 ft

So, the height of the soccer ball 1.25 seconds after Callie kicks it is 22.5 ft

The car will take 15 minutes to drive to the next stop which is 16 miles away.

As per the question statement, we are supposed to find the time taken by the car to drive to the next stop which is 16 miles away if it is driving on the interstate with cruise control on at a constant speed of 64 miles per hour.

Before solving the question, we need to know the concept of relation between time, distance and speed, which states that

[tex]speed=\frac{distance}{time}[/tex]

In the question [tex]speed = 64 mph\\distance = 16 miles\\time taken = t[/tex]

Substituting values in the formula above,

[tex]64=\frac{16}{t} \\t=\frac{16}{64} \\t=0.25 hours =0.25 *60\\t=15 minutes[/tex]

Hence the time taken by car  to drive to the next stop which is 16 miles away is 15 minutes or [tex]\frac{1}{4}[/tex] hours.

As per the question statement, a clown juggles 12 bowling for the first 2.5 minutes then he bump it up to an average of 18 bowling pins per minute for the last [tex]1\frac{1}{3}[/tex]  minute (Mixed Fraction form)

We are supposed to find the total number if pins by the clown.

Let's calculate the total time first that will be 2.5 minutes + [tex]1\frac{1}{3}[/tex] minutes

[tex]1\frac{1}{3} =\frac{3*1 +1}{3} =\frac{4}{3} =1.34[/tex] minutes.

Therefore total time = 3.84minutes

Given that he bumps it up to an average of 18 bowling pins per minute for the last [tex]1\frac{1}{3}[/tex]  minute so, the number of pins in the last  [tex]1\frac{1}{3}[/tex]  minute will be = [tex]18*1.34 = 24.12 = 25[/tex] (approx.)

The area of the polygon is approximately 24.497 square units.

In accordance with the statement, we have a polygon with three vertices set on Cartesian plane, that is, a triangle. We need to find the side lengths first and later to calculate the area by Heron's formula. First, determine the lengths of each line segment by Pythagorean theorem:

JK = √[[4 - (- 3)]² + (4 - 4)²]

JK = 7

KL = √[(3 - 4)² + (- 3 - 4)²]

KL = √[(- 1)² + (- 7)²]

KL = 5√2

JL = √[[3 - (- 3)]² + (- 3 - 4)²]

JL = √85

Second, calculate the area of the triangle:

s = (JK + KL + JL) / 2

s = (7 + 5√2 + √85) / 2

s ≈ 11.645

A = √[s · (s - JK) · (s - KL) · (s - JL)]

A = √[11.645 · (11.645 - 7) · (11.645 - 5√2) · (11.645 - √85)]

A ≈ 24.497

The solution set of the inequality for R is given by [tex]-\frac{1172}{85} \leq x\leq \frac{1228}{55}[/tex] .

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.  It is frequently used to compare two numbers on the number line based on their sizes. Different types of inequalities are represented by a variety of notations such as < ,> ,≤ and ≥.

The modulus function takes the absolute value of a function.

To solve the given inequality we have simplify the inequality first.

[tex]x-\frac{7}{9} |(\frac{12}{5} -6x)|+50\ge -30[/tex]

[tex]or, x-\frac{7}{9}\times \frac{6}{5} |(2-5x)|+50\ge -30\\or,x-\frac{14}{15}|2-5x|\ge-80\\[/tex]

Now we separate the inequalities:

[tex]x-\frac{14}{15}(2-5x)\ge-80[/tex]  for 2x-5 ≥ 0

[tex]x-\frac{14}{15}(-(2-5x))\ge-80[/tex]  for 2x-5 ≤ 0

Now we will solve the two inequalities separate and find the intersection.

[tex]x-\frac{14}{15}(2-5x)\ge-80\\or,15x-28+70x\ge-1200\\or,x\ge -\frac{1172}{85}[/tex]

2x-5 ≥ 0

or, [tex]x\le\frac{2}{5}[/tex]

hence [tex]-\frac{1172}{85}\le x\le\frac{2}{5}[/tex]

Similarly solving the other inequality we get

[tex]\frac{2}{5}\le x\le\frac{1228}{55}[/tex]

The vehicle will get speed of approximately 15 mph and -210 mph.

Science's most important concept is measurement. Many measurable quantities are measured in fundamental or base units. One such measurable quantity is speed, which is defined as the ratio of an object's distance travelled to the time required to travel that distance. Let us learn about speed in depth during this session.

The ratio of distance to time taken to cover a distance is used to calculate speed. Because it only has one direction and no magnitude, speed is a scalar quantity.

Given the equation for gas mileage = 0.02x² + 3.9x  - 43 where x means speed

We have been asked to find x if gas mileage = 20 that is

0.02x² + 3.9x  - 43 = 20

Lets simplify

⇒ 0.02x² + 3.9x  - 43 = 20

⇒ x² /50 + 39x/10  - 63 = 0

⇒ x²/ 50 + 195x/50 - 3150 = 0

⇒ 1/50 (x + 195x - 3150 ) = 0

⇒ 1/50 (x + 210x - 15 x - 3150 ) = 0

⇒ 1/50 (x (x+210) −15 (x+210)) = 0

⇒ 1/50 (x−15)(x+210) = 0

⇒  (x−15)(x+210)  = 0 × 50

⇒ (x − 15)(x + 210)  = 0
