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.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the cost of hamburger, y represent the cost of french fries and z represent the cost of soda, hence:

x + y = 13   (1)

Also:

x + 2z = 14    (2)

And:

x + y + z = 16    (3)

From the three equations:

x = 8, y = 5, z = 3

The cost of each hamburger is $8, the cost of each French fry is $5 while the cost of each Soda is $3.

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]

The expression 6-3/6-4 after simplification will look like 1.5.

Given that the expression is 6-3/6-4.

We are required to find the value after simplification.

Simplification or simplify fractions basically means to simplify a complicated mathematical expression to get a single or direct answer.

We have to use BODMAS rule for the simplification. The full form of BODMAS is Brackets, Open, Division, Multiplication,Addition and Subtraction. Simplication is nothing but to reduce the expression.

The expression is  6-3/6-4.

We have to do division first.

6-3/6-4 =6-0.5-4

Now we have to do subtraction now.

6-0.5-4=5.5-4=1.5

Hence the expression 6-3/6-4 after simplification will look like 1.5.

After juggling for several minutes i.e., 2.5 minutes and [tex]1\frac{1}{3}[/tex] minutes (mixed fraction), the total number of bowling pins by clown is 37 pins

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 quotient of the given problem using laws of exponents is; 6 * 10⁰

We want to express the quotient of the quantity 30 times ten raised to the negative twenty fourth power end quantity divided by the quantity 5 times ten raised to the negative twenty fourth power end quantity.

This is;

(30 * 10⁻²⁴)/(5 * 10⁻²⁴)

Now, we can break this down into like terms to get;

(30/5) * (10⁻²⁴/10⁻²⁴)

The small will grow 19/4 inch in 3 weeks and the method which will not give the correct inches will be the first option which is

                       multiply [tex]2\frac{1}{2} * 3[/tex] and then add 3/4.

According to the question we have been given that

The height of the small plant = [tex]2\frac{1}{2}[/tex] inch

In  1 week the plant grows = [tex]\frac{3}{4}[/tex] inch

We need to find the height of the small plant after 3 weeks.

For that we will first find how much tall it will be in 3 weeks using unitary method that is,

                              1 week = [tex]\frac{3}{4}[/tex] inch

                               3 week = [tex]\frac{3}{4}[/tex]  * 3 inch

                                          = 9/4 inch

Therefore the height of the small plant after 3 weeks will be

                         [tex]=2\frac{1}{2} + \frac{9}{4} \\= \frac{5}{2} + \frac{9}{4}\\= \frac{10+9}{4} \\= \frac{19}{4}[/tex]

hence the height is 19/4 inch

And the method which will not give the correct number of inches is the first option which is

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 value of the functions f(6), f(- 10), f(0) are 9, 7 and 3 respectively.

A function can be defined as an expression, rule or law that shows the relationship between a dependent and an independent variable.

Given the function;

f(x) = |x+3|

To determine f(6)

Substitute the value of x as 6

We have;

f(6)  = | 6 + 3 |

f(6) = 9

To determine f(-10)

Substitute the value of x as - 10

We have;

f(-10) = | -10 + 3 |

f(-10) = | -7|

f(-10) = 7

To determine f(0)

Substitute the value of x as 0

We have;

f(0) = | 0 + 3|

f(0) = 3

Thus, the value of the functions f(6), f(- 10), f(0) are 9, 7 and 3 respectively.

Part b: Percentage of acid in the resulting mixture = 36.88%.

Part a: Find the both values from the given percentage;

225 millilitres of a solution contains is 39% acid.

39% of 225 = (39×225)/100 = 87.75 millilitres.

You need to add 6 red marbles for the ratio to stay the same

The given parameters are:
