[tex] \rm \bigg \{(x,y) \in \mathbb{R} \times \mathbb R : |x| \leq \dfrac{3}{4} ,0 \leq y \leq min \{f(x),g(x) \} \bigg \}[/tex]
then the value of 9[tex]\alpha[/tex]​

Answers

Answer 1

Suppose [tex]x>0[/tex]; then the curves meet when

[tex]x^2 + \dfrac5{12} = 2 - \dfrac83 x \implies x^2 + \dfrac83 x - \dfrac{19}{12} = \left(x + \dfrac{19}6\right) \left(x - \dfrac12\right) = 0 \\\\ \implies x = \dfrac12[/tex]

By symmetry, they intersect at [tex]x=\pm\frac12[/tex].

We also see that [tex]\min\left\{f(x):|x|\le\frac34\right\} = \frac5{12}[/tex] and [tex]\max\left\{g(x):|x|\le\frac34\right\} = 2[/tex] at [tex]x=0[/tex]. [tex]f[/tex] and [tex]g[/tex] are continuous, so it follows that

[tex]\min\left\{f(x),g(x) :|x|\le\frac34\right\} = \begin{cases} f(x) & \text{if } |x| < \frac12 \\ g(x) & \text{if } |x| > \frac12 \\ f\left(\pm\frac12\right) = g\left(\pm\frac12\right) = \frac23 & \text{if } x = \pm\frac12 \end{cases}[/tex]

Compute the area [tex]\alpha[/tex]. Taking advantage of symmetry again, we have

[tex]\alpha = \displaystyle 2 \int_0^{1/2} \int_0^{f(x)} dy\,dx + 2 \int_{1/2}^{3/4} \int_0^{g(x)} dy \, dx \\\\ ~~~~ = 2 \int_0^{1/2} f(x) \, dx + 2 \int_{1/2}^{3/4} g(x) \, dx \\\\ ~~~~ = \left. 2 \left(\frac{x^3}3 + \frac{5x}{12}\right) \right\vert_0^{1/2} + \left. 2 \left(2x - \frac{8x^2}6\right) \right\vert_{1/2}^{3/4} \\\\ ~~~~ = \left(\frac12 - 0\right) + \left(\frac32 - \frac43\right) = \frac23[/tex]

and it follows that [tex]9\alpha = \boxed{6}[/tex].

100°F. Your friend has a temperature of 37°C. Does your friend have a
fever when the temperature increases by 1°F? 1°C?

Answers

The friend doesn't have a fever when the temperature increases by 1°C.

How to convert the temperature?

To convert Celcius to Fahrenheit,we have to multiply by 1.8 and add 32°.

This will be:

37°C = (37 × 1.8) + 32

= 98.6

When we add 1°, we will get 99.6.

Therefore, the friend doesn't have a fever when the temperature increases by 1°C.

11. Descartes
has $9. He works 5 hours
and earns $8 each hour. Write an
expression
to represent the situation

Answers

Answer: y = 8x + 9

Step-by-step explanation: Descartes begins with only $9.00, so 9 is the y-intercept. He makes $8.00 every hour, so that is the slope.

y = mx + b

m is the slope, and b is the y-intercept.

y=8x + 9

The expression that represents the given situation is y = $49.

What is an expression?

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it isgiven that,

Descartes has Money = $9

Each hour earning = $8

Total time of work = 5 hours

So, total money earned in 5 hours = 8*5 = $40

Let y be the total money Descartes has.

So total money Descartes has = Money + total money earned in 5 hours

⇒ y = $9 + $40

⇒ y = $49

This is the required expression for the present situation.

Thus, The expression that represents the given situation is y = $49.

Answer:

x = - 7.5

Solution~:

[tex]\frac{1}{5}x+\frac{1}{4}=\frac{1}{2}\left(x+5\right)[/tex]

Distribute:

[tex]\frac{1}{5}x+\frac{1}{4}=\frac{1}{2}x+\frac{5}{2}[/tex]

Subtract 1/4 from both sides:

[tex]\frac{1}{5}x+\frac{1}{4}-\frac{1}{4}=\frac{1}{2}x+\frac{5}{2}-\frac{1}{4}[/tex]

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

Subtract 1/2x from both sides:

[tex]\frac{1}{5}x-\frac{1}{2}x=\frac{9}{4}+\frac{1}{2}x-\frac{1}{2}x[/tex]

[tex]-\frac{3}{10}x=\frac{9}{4}[/tex]

Multiply both sides by 10:

[tex]10\left(-\frac{3}{10}x\right)=\frac{9\cdot \:10}{4}[/tex]

[tex]-3x=\frac{45}{2}[/tex]

Divide both sides by -3:

There are 9 rows in first class and 24 rows in economy.
Write down an expression, in terms of s and t, for the number of seats on the
airplane.

Answers

The expression, in terms of s and t, for the number of seats on the airplane is given by 24 s + 9 t.

We are given that there are 2 types of seating in an airplane which are economy and first class seating.

Also,

We are given that:

There are s seats in economy in each row and there are t seats in first class in each row.

Now, there are 24 rows in economy class seating.

So, number of seats in economy class = 24 × s = 24 s

And, there are 9 rows in first class seating.

So, number of seats in first class = 9 × t = 9 t

The total number of seats then will be = 24 s + 9 t

Therefore the expression, in terms of s and t, for the number of seats on the airplane is given by 24 s + 9 t.

containers does she need? How many oatmeal and chocolate chip cookies will be in each container?

Answers

The greatest possible containers required by Kiara is 4.

The number of oatmeal and chocolate chip cookies in each container is 3 and 4 respectively.

What is defined as the highest common factor?The highest common factor, or HCF, is the greatest number that divides each of two or more numbers.HCF is also recognised as the Greatest Common Measure (GCM) and the Greatest Common Divisor (GCD) .

For the given question;

The total number of oatmeal cookies = 12.

The total number of chocolate chip cookies = 16.

Taking the HCF of 12 and 16 (the largest multiple pf 12 and 16).

HCF = 4.

Thus, the number of boxes requires is 4.

The oat place in one box is 3. In 4 boxes it will be 12.

Similarly, the chocolate chip cookies placed in one box is 4. In 4 boxes it will be 16.

the peremiter of a parallelogram is 56 meters The width of the parallelogram is 4 meters less than its length find the length and the width of the parallelogram

Answers

The length of the parallelogram is 16 m and the width of the parallelogram is 12 m.

We are given that the perimeter of a parallelogram is 56 m.

Let the length of the parallelogram be x meter.

So, we get that the width of the parallelogram will be = x - 4 meter.

We also know that:

Perimeter of parallelogram = 2 ( l + b )

Substituting the values in this, we get that:

56 = 2 ( x + x - 4 )

56 = 2 ( 2 x - 4 )

28 = 2 x - 4

2 x - 4 = 28

2 x = 28 + 4

2 x = 32

x = 16

Length = 16 m

Width = 16 - 4 = 12 m

Therefore, the length of the parallelogram is 16 m and the width of the parallelogram is 12 m.

A spinning disk with radius 10 cm rotates at 120 rpm.
1. Find the angular speed:
2. Find the linear speed of a point on the edge of the disk:

Answers

1) The angular speed is approximately 12.566 radians per second.  

2) The linear speed of a point on the edge of the disk is 1.257 meters per second.

What are the angular speed and the linear speed of a spinning disk?

1) Herein we have a disk that spins at constant angular speed (ω), in radians per second, whose magnitude is found dimensional analysis and unit conversions:

ω = 120 rev / min × (2π rad / 1 rev) × (1 min / 60 s)

ω ≈ 12.566 rad / s

The angular speed is approximately 12.566 radians per second.  

2) The linear speed (v), in meters per second, on the edge of the disk is described by the following formula:

v = R · ω  

Where R is the radius of the spinning disk, in meters.

If we know that R = 0.1 m and ω ≈ 12.566 rad / s, then the linear speed is:

v = (0.1 m) · (12.566 rad / s)

v = 1.257 m / s
