Answer:

The least common denominator of the expression is 72g.

Step-by-step explanation:

First, let us write the expression out mathematically

[tex]\frac{g^{2} }{9} - g^{2} + 14 + \frac{g}{24g} + 8g^{2}[/tex]

The denominators in the expression are 9 and 24g. To find the least common denominator, we will determine the least common multiple of the numbers (9 and 24) first, and then find the least common multiple of the result and g (since it is the only letter).

Multiples of 9 = 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...

Multiples of 24 = 24, 48, 72, 96, ...

The least common multiple of 9 and 24 is 72.

Then, the least common multiple of 72 and g is 72g

Hence, the least common denominator of the expression is 72g.

The coordinates of Ship A and B are missing, so i have attached it

Answer:

The vessel in distress is located at the coordinate (1, 2)

Step-by-step explanation:

The coordinates attached shows that;

Coordinates of A are (3, 4) while that of B are (1, 1).

We are told that Ship A receives a distress signal from the north, And ship B receives a distress signal from the same vessel from the southeast.

Now, from the image attached, If we imagine extending the line of ship A that is getting distress signal from southeast and also same thing for ship B that is getting signal from north,we'll discover that the lines intersect at a point with co-ordinates of approximately; (1, 2)

What's the answer

Step-by-step explanation:

The recursive function f(7) is = 7.f(8).

A recursive function is a form of arithmetic or geometric sequence which repeats.

According to the given question f(5) = 20.58 and f(6) = 2.9.

Given it is a recursive function so it could be in form of arithmetic sequence or geometric sequence.

We have asked f(7) is how many times of f(8) from here we can conclude that it is in the form of geometric sequence.

f(5) = 20.58 and f(6) = 2.94 so the common ratio of n/(n-1) is

= 20.58/2.94

= 7.

Or we can say that f(5) is 7 times of f(6) which is 7.f(6) = f(5).

∴ f(7) = 7.f(8) = (1/7)f(6) = 0.42.

==========================================

Explanation:

55 is close to 50

99 is close to 100

55/99 is close to 50/100 = 1/2

Using a calculator, 55/99 = 0.556 approximately which rounds to 0.5 = 1/2

Answer:

Below

Step-by-step explanation:

Let y' = mx + b be the equation of the second line

● m is the slope

● b is the y-intercept

The lines are parallel so they have the

same slope.

● y' = 3x + b

The second line crosses the point with the coordinates (2,11)

Replace y' by 11 and x by 2 to find b

● 11 = 3×2 + b

● 11 = 6 + b

Substract 6 from both sides

● 11 - 6 = 6 + b -6

● b = 5

So

● y' = 3x + 5

Step-by-step explanation:

Answer:

Total cost is 2,800

Step-by-step explanation:

The given ratio 5:7:13 represents profit to cost of materials to labour.

However it is stated that cost of materials is Le 840 more than that of labour

Cost of material - 840 = labour

Cost of material = labour - 840

Let

Cost of material be x, and labour be y

x ÷ y = 7 ÷ 13 (equation 1)

x = y - 840 (equation 2)

Substitute x from equation 1 in equation 2

(y - 840) ÷ y = 7 ÷ 13

13 (y -840) = 7y

y = 1,820

Substitute value of y in equation 2

x = 1820 - 840

x = 980

So total cost is cost of material plus cost of labour = 980 + 1820 = 2,800

This will satisfy the ratio of 5:7:13 representing profit to cost of materials to labour

Answer:

C

Step-by-step explanation:

Here, we want to know what what the display on the calculator means.

Well, the expression has to do with how scientific calculators display powers of 10.

So what this means is that the value 3.456 is raised to the power of 14.

This is a way in which the screen of the scientific calculators maximizes the space on their screens.

Perhaps, we have the result of a multiplication to the powers of 27. It would be quite funny seeing 27 zeros lying on the screen of the calculator right? isn’t it?

So the calculator makes a better way of this by just printing E 27 and this automatically means 10 raised to the power of 27

This makes our answer C

Kindly note that the + sign indicates that the power of the 10 is positive 14.

Answer:  see proof below

Step-by-step explanation:

Use the following Sum Identities:

cos (A + B) = cosA · cosB - sinA · sinB

sin (A + B) =  sinA · cos B - cosA · sinB

Use the Unit Circle to evaluate the following:

cos 30 = √3/2                            sin 30 = 1/2

cos 45 = √2/2                            sin 45 = √2/2

cos 120 = -1/2                             sin 120 = √3/2

cos 240 = -1/2                             sin 240 = -√3/2                        

cos 315 = √2/2                           sin 315 = -√2/2        

cos 330 = √3/2                          sin 330 = -1/2

Proof LHS → RHS

[tex]\text{LHS:}\qquad \qquad \dfrac{\cos 285+\cos 345}{\sin 435-\sin 375}[/tex]

[tex]\text{Expand:}\qquad \quad \dfrac{\cos (240+45)+\cos (315+30)}{\sin (315+120)-\sin (330+45)}[/tex]

[tex]\text{Sum Identity:}\qquad \dfrac{\cos 240\cdot \cos 45-\sin 240\cdot 45+\cos 315\cdot \cos 30-\sin 315\cdot 30}{\sin 315\cdot \cos 120+\cos315\cdot \sin 120-(\sin330\cdot \cos45+\cos 330\cdot \sin 45) }[/tex]

Step-by-step explanation:

To solve this equation, we can use basic algebraic techniques as illustrated.

3(x + 4) = 7x Distribute the 3.

3x + 12 = 7x Subtract 3x from both sides of the equation.

12 = 4x Rearrange the equation so the variables are on the left.

4x = 12 Divide by 4 on both sides of the equation.

Given that,

The area of a blackboard is [tex]1\dfrac{1}{3}=\dfrac{4}{3}\ \text{yards}^2[/tex]

The area of poster is [tex]\dfrac{8}{9}\ \text{yards}^2[/tex]

We need to find the unit rate of the blackboard's area to the poster's area. So, it can be calcualted by dividing blackboard's area to the poster's area.

So,

[tex]\dfrac{\dfrac{4}{3}}{\dfrac{8}{9}}=\dfrac{4}{3}\times \dfrac{9}{8}\\\\=1.5[/tex]

So, the rate of [tex]1.5\ \text{yard}^2[/tex].

Answer:

            5 spugs is 560% of 1 spig

Step-by-step explanation:

a - spig

b - speeg

c - spoog

d - spug

40% of one spig is a spoog:  40%a = c

25% of a speeg is a spoog:    25%b = c

70% of a speeg is a spug:       70%b = d

what percent of 1 spig is 5 spugs?:     x%a = 5d

40%a = c  and  25%b = c

40%a = 25%b

[tex]b=\frac{40\%a}{25\%}=1.6a[/tex]

d = 70%b = 70%•1.6a = 112%a

x%a = 5d

x%a = 5•112%a

÷a         ÷a

x% = 560%

Answer:

Max Area = 105,800 sq.ft

Step-by-step explanation:

A square will always give us the maximum area.

Thus, one side would be;

920/4 = 230 feet

So, we want a square 230 ft by 230 ft

however, from the question, we are to use the creek as one side. So, we'll take the 230 ft that we don't need because of the creek and then add it to the opposite side to get 230 + 230 = 460 ft.

Thus,we now have a rectangle with dimensions: 230 ft by 460 ft

Area is given by;

area = length × width

Maximum Area = 230 × 460

Max Area = 105,800 sq.ft

2=±4

Case 1  2=+4

=±2√

√=±(12√+12√)

=±2‾√+2‾√

Case 2  2=−4=43

=±23/2=±2()1/2

∵√=±(12√+12√)

=±(2‾√+2‾√)

So in all,

=2‾√+2‾√

=−2‾√+2‾√

=2‾√−2‾√

=−2‾√−2‾√

Let  √=+

Squaring both sides, we have

=(+)2

0+1=2−2+2⟹

2−2=0(1)

2=1

=12

Plugging in  (1)  … ⟹

2−1(2)2=0

4=14

2=12

∴=±12‾√

∴=±12‾√

∴√=+=±(12+12)

This can also be shown as below

√=12+12

Or

√=−12−12 \
