Step-by-step explanation:

the given family of functions is the general solution of the differential equation on the indicated interval y=[tex]7/2e^{x} -7/2e^{-x}[/tex]

What is differential equation?

Equations which involves functions and its derivative is known as differential equation. these equations are highly used to model behaviour of complex system.

How to solve?

y(x) = [tex]C_{1} e^{x}+C_{2}e^{-x}[/tex]

y(0) = [tex]C_{1} +C_{2}[/tex]

0 =[tex]C_{1} +C_{2}[/tex]  --------------------------------------------------(1)

y'(x) =   [tex]C_{1}e^{x} -C_{2}e^{-x}[/tex]

y'(0) =  [tex]C_1- C_{2} }[/tex]

7 =  [tex]C_{1}-C_{2}[/tex] -------------------------------------------------(2)

From Equation 1 and 2

[tex]C_{1} +C_{2}[/tex] = 0

[tex]C_{1} -C_{2}[/tex] = 7

[tex]C_{1}[/tex] = 7/2

[tex]C_{2}[/tex] = -7/2

y=[tex]7/2e^{x} -7/2e^{-x}[/tex]

the complete question is

The given family of functions is the general solution of the differential equation on the indicated interval. Find a member of the family that is a solution of the initial-value problem. y = c1ex + c2e−x, (−∞, ∞); y'' − y = 0, y(0) = 0, y'(0) = 7

The length and width of the rectangular field is found as width x = 2.08 m and length = 5.16 m.

The given values in the question are-

The width of the field = w.

The length of the field = 2x+1

The area of the field =  600 m².

The formula of area of rectangular field;

A = length×width

Put the values;

600 = (2x+1)x

Simplifying the equation;

600 = 2x² + x

2x² + x - 600 = 0.

Find the factors of the above quadratic equation using quadratic formula.

x = 2.08, neglecting negative value.

Thus, the width is x = 2.08 m.

length = 2x + 1

length = 5.16 m.

Thus, the length and width of the rectangular field is found as width x = 2.08 m and length = 5.16 m.

The body mass index of a person 65 inches tall with a weight of 175 pounds is 29.12

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

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

The body mass index (BMI) is given by:

BMI = [mass in pounds / (height in inches)²] * 703

Given mass = 175 pounds, height = 65 in, hence:

BMI = [175/65²] * 703 = 29.12

BMI = 29.12

The value of the net force acting on the block will be equal to 79N.

Force may be defined as the product of mass and acceleration, and it acts on the body in order to move the body. Since, the external force is acting on the block there will be a frictional force which opposes the block to move. The frictional force may be represented by f(k) and is given by

f(k) = external force - (ma)

f(k) = 40N - (5×6)

f(k) = 40N - 30N

f(k) = 10N and since it opposes the external force then the sign will be negative that is f(k) = -10N.

Also, there is a force of gravity acting on the body which will be equal to mg where 'g' is the acceleration due to gravity.

Now, force of gravity = mg

= 5×9.8 = 49N

Now, net force acting on the block = 40N - 10N + 49N

Answer:

The farmer had to do 27 loads.

Step-by-step explanation:

Basically the easy way to do this is to grab a calculator (or the paper and pen way) and keep adding 336 until you get to 8914.

Once you add it all you will see there is a remainder of his corn left (that has not been delivered):178

Even though it isn't a full 336, the farmer would still have to make another trip.

336*26=8,736

So, adding the remainder into it's own load, we would get:

27.

We determine the scale factor by comparing the lengths of corresponding sides of the square.

The length of O’N’=15 and the length of the corresponding segment ON =9.
Then, we compute the scale factor:
O’N’=kON

15=9k

k=15/9=5/3.

The scale factor is k=5/3.

The solution of the equation b² = 48 is b = 4√3

The equation can be solved as follows;

b² = 48

Therefore, we are to find the value of b in the equation.

The value of b comes with a square sign, so we have to remove the square to make b stand alone in the equation.

By removing the square sign we have to square root both sides.

Hence,

b² = 48

square root both sides of the equation

b² = 48

√b² = √48

Therefore,

b = √16 × 3

b = 4√3

Only height, because when you have an expression that relies only on multiplication (not addition or subtraction), we'll say:

cb = a

Tripling either c or b will also triple a. For example:

(8)(3) = 24

(8 + 8 + 8)(3) = 24(3)
(24)(3) = 24(3)

This will be true even if you multiply c by any other number.

So, in the expression v = πr²h, any term except r can be tripled with the result of tripling v. We exclude r because r has an exponent, which means tripling r will more than triple v.

Answer:

m arcRP = 125°

m arcQS = 125°

m arcSP = 55°

m arcQR = 55°

Step-by-step explanation:

An arc is the curve between two points on the circumference of a circle.

An arc measure equals its corresponding central angle measure.

Vertical Angles Theorem:  When two straight lines intersect, the opposite vertical angles are congruent.

Angles on a Straight Line Theorem:  The sum of angles formed on a straight line is equal to 180°.

As m∠ROP = 125°

Therefore, m arcRP = 125°

Given the measure of angle ROP is 125°, and an arc measure equals its corresponding central angle measure, the measure of arc RP is 125°.

Using the Vertical Angles Theorem:

⇒ m∠QOS = 125°

Therefore, m arcQS = 125°

Using the Vertical Angles Theorem, the measure of angle QOS is equal to the measure of angle ROP, so the measure of angle QOS is 125°. As an arc measure equals its corresponding central angle measure, the measure of arc QS is 125°.

Using the Angles on a Straight Line Theorem:

⇒ m∠SOP = 180° - 125° = 55°

Therefore, m arcSP = 55°

Using the Angles on a Straight Line Theorem, the measure of angle SOP is 55°. As an arc measure equals its corresponding central angle measure, the measure of arc SP is 55°.

Using the Angles on a Straight Line Theorem:

⇒ m∠QOR = 180° - 125° = 55°

Therefore, m arcQR = 55°

Using the Angles on a Straight Line Theorem, the measure of angle QOR is 55°. As an arc measure equals its corresponding central angle measure, the measure of arc QR is 55°.

By using Binomial probability distribution, the mean number of adults who would have bank savings accounts is 32.

For every survey, there are only two possible outcomes.

First- they have bank savings accounts,

second- they do not.

So, by using the binomial probability distribution we can solve this problem.

Probability of exactly Y successes in ‘n’ repeated trials, with ‘p’ probability.

Probability = p

Successes repeated = n  times

The  value of the binomial distribution is:

E(Y) = n x p

In this problem, we have that:

p = 0.64

If we were to survey among 50 randomly selected adults, the mean number of adults who would have bank savings accounts is,

E(Y) when, n = 50

So,

E(Y)= n x p

= 50 x 0.64

= 32

Hence ,our required answer is 32 adults who would have bank savings accounts
