what is the answer for this math question -q/7>-1 im stuck on it

Answers

Answer 1

All possible solutions for inequality are (-∞,-7)U(-7, ∞).

What is inequality?

In mathematics, a relationship between two expressions or values that are not equal to each other is called 'inequality. ' So, a lack of balance results in inequality.

The inequality q/7 > -1 is a mathematical statement that compares the value of q/7 to -1.

To solve the inequality, we can start by isolating q on one side of the inequality.

To do this, we need to multiply both sides of the inequality by 7:

q/7 * 7 > -1 * 7

q > -7

Now we have the inequality q > -7, this inequality states that q is greater than -7.

To find all possible solutions for the inequality, we can use interval notation. The interval notation for the solution of this inequality is (-infinity,-7)U(-7, infinity)

It means all real numbers except -7, the solution set is an open interval.

Alternatively, we can also graph the solution set of the inequality on a number line, shading the region that represents the solution. The shaded region will be all the points to the right of -7 on the number line.

Hence, all possible solutions for inequality are (-∞,-7)U(-7, ∞).

What is the change of base property?

Answers

The change of base property is a formula that makes it possible to express a logarithm in terms of logs expressed in a different base.

It is possible to express a logarithm in terms of logs stated in a different base using the change of base property formula. This is especially useful when evaluating a log to a base other than 10 or e using a calculator. X, a, and b are all taken to be positive. The base change property can be used to simplify equations with different bases for the logarithmic terms. All the logarithmic terms of an equation with logarithmic functions should have the same base in order to be solved.

Answers

a. Drive Co.'s revenue function R(X) = (-x^2/5)-247x.

b. The price per drive when revenue is maximized is $370.6.

c. The maximum profit made from the sale of these drives if Drive Co. incurs production costs of $179 per drive and has fixed costs of $250 is $6030.

What is a function?

The characteristic that every input is associated to exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs.

Drive Co. sells portable 905 hard drives when the price is $66/drive and can sell 800 hard drives when the price is $87/drive.

Let p be the price of hard drive and x be the number of hard drives.

When x = 905, then p = 66.

So, (x1,p1) = (905,66)

Similarly, when x = 800, then p = 87.

So, (x2,p2) = (800,87)

So, the equation of line between x and p is given as -

p-p1=[(p2-p1)/(x2-x1)}(x-x1)

Plugging in the values -

p-66=[(87-66)/(800-905)](x-905)

p-66=(21/-105)(x-905)

-105p+6930=21x-19005

-105p-21x=-19005-6930

-105p-21x=-25935

p=(-21x/105)-247

p=(-x/5)-247

So, the price function p(x) = (-x/5)-247.

Now, derive the revenue function -

Revenue = Number of drives × price per drive

Revenue = x · p(x)

Revenue = x · (-x/5)-247

Revenue = (-x^2/5)-247x

Therefore, the revenue function R(x) = (-x^2/5)-247x.

For maximum revenue -

dR/dx = R'(x) = 0 and R''(x)<0

dR/dx = -2x/5-247 = 0

-2x/5 = 247

x = -1235/2

x = -617.5

Therefore, the number of drives at maximum revenue is 618 drives.

The price per drive is -

p(618) = {-618/5}-247

p(618) = -370.6

Therefore, the price per drive is $370.6.

Now, the profit S(x) = Revenue R(x) - Total Cost C(x)

C(x) = fixed cost + variable cost

Variable cost = number of drives × price per drive

C(x) = 250 + 179x

Substituting the values -

S(x) = [(-x^2/5)-247x] - [250+179x]

S(x) = (-x^2/5)-68x-250

In order to get maximum profit differentiate the equation and equate it to 0.

dS/dx = 0

dS/dx = -2x/5-68 = 0

-2x/5 = 68

x = 340/-2

x = -170

d^2S/dx^2 = -2/5<0

So, maximum profit will be at x = 170.

S max = S(170) = [(170)^2 /5] - 68 (170) - 250

= 5780 - 11560 - 250

= -6030

Therefore, the maximum profit earned is $6030.

Answers

Answer:  ∠M = 98°

Step-by-step explanation:

Given:

∠M = (3x-16)°

∠N = x°

∠O = (x+6)°

Sum of all angles in a triangle is 180°

Therefore, 180° = ∠M +∠N +∠O, substitute the given values

180° = (3x-16)° + x° + (x+6)° (add/combine like terms)

180° = (3x+x+x)° + (-16+6)°

180° = (5x)° + (-10°)

180° + 10° = (5x)° ( divide both sides by 5)

190°/5 = (5x)°/5

38° = x°

IF ∠M = (3x-16)°, substitute x°=38°,

Therefore, ∠M = 3(38)-16

                   ∠M = 114 - 16 = 98°

What is slope-intercept form of line?

The slope intercept form equation for a straight line with a slope, 'm', and 'c' as the y-intercept can be given as:

y = mx + c.

Given,

No. of pages Lin read on day of planning = 30

No. of pages she plans to read everyday = 40

If total pages are y for x days then,

y = 40x + 30

which is the original plan of Lin.

comparing it with slope-intercept form of line

y = mx + c

slope m = 40

vertical intercept of original plan c = 30 unit

slope m represents the no. of pages read everyday.

vertical intercept represents the no. of pages read on day of planning.

vertical intercept c' of line drawn by Lin = 40 unit

Comparing intercept of original plan to line drawn by Lin

= |c - c'|

= |30 - 40|

= 10 unit

If the number of bees in the population after x years is represented by f(x), which statements about the situation are true? Check all that apply.

Answers

The correct options regarding given function  are (b), (c) and (f).

What is a function?

An association between each element of a non-empty set A and at least one element of a different non-empty set B is called a function.

The set of values that we are permitted to enter into our function is known as the domain of a function.

A function's range is the collection of values it gives as outputs.

The options given are:

a)The function f(x) = 9,000([tex]1.05^{x}[/tex]) represents the situation.

b)The function f(x) = 9,000([tex]0.95^{x}[/tex]) represents the situation.

c)After 2 years, the farmer can estimate that there will be about 8,120 bees remaining.

d)After 4 years, the farmer can estimate that there will be about 1,800 bees remaining.

e)The domain values, in the context of the situation, are limited to whole numbers.

f)The range values, in the context of the situation, are limited to whole numbers.

Now given,

Number of bees initially = 9000

Rate of decay = 5%

f(x) = Number of bee population after x years

 

So, f(x) = 9000([tex]0.95^{x}[/tex])

After 2 years, number of bees is

  f(2) = 9000(0.95²) = 8122.5 ≈ 8120

After 4 years, number of bees is

 f(4) = 9000(0.95⁴) = 7330.56≈7330

The domain of the function is number of years(x) which can be whole as well as decimal numbers.

The range of the function is number of bees after x years, which should be a positive integer number. So whole numbers are the domain.

Therefore the correct options regarding given function  are (b), (c) and (f).

The average rate of change for the quadratic function in the graph is 1

What is average rate of change of quadratic function?

The proportion of change along the y-axis to change along the x-axis represents the average rate of change between the two points.

Since the graph of a quadratic function is curved and lacks a constant rate of change between any two distinct locations, it is referred to as the average rate of change rather than the slope.

The average rate of change between points (2, 0) and (3, 1) is

= (0 - 1) / (2 - 3)

=-1 / -1

= 1

The average rate of change within the interval 1 to 3 is 1

One of the two variables on the two sides of the inequality may be greater than, greater than or equal to, less than, or less than or equal to another value, according to inequality signals.

There are four ways to depict an inequality: solution graph, interval notation, set notation, and equation notation.

A comparison of any two values, known as an inequality, demonstrates whether one value is less than, larger than, or equal to the value on the opposite side of the equation. A relationship in a real-world scenario can be demonstrated by writing an inequality.

a. 60
b. 64
c. 84
d. 85

Answers

64 marks must he score on her fourth exam to get exactly 80% in the course.

From the question, we are informed that Lisa is currently taking physics as one of her electives in school and that her grade at the end of the year is determined by the average of four exams, each worth 100 points.

First test = 84,

Second test = 92

Third test = 80

Forth test = y

And,

The fourth test is denoted by y.

Since we are told that she must get exactly 80% in the course and she took 4 exams, that means her total score will be: = 80 × 4 = 320

Therefore,

⇒ 84 + 92 + 80 + y = 320

⇒ 256 + y = 320

⇒ y = 320 - 256

⇒ y = 64

The fourth exam's score is 64.
