Answer:

[tex]f(x)=16\, (\frac{3}{2} )^{x-1}[/tex]

Step-by-step explanation:

Since we are given the common ratio (3/2), all we need to find to define the geometric sequence, is its multiplicative factor ([tex]a[/tex]) that corresponds to the first term of the sequence - remember that all consecutive terms will be generated by multiplying this first value repeatedly by the common ratio (3/2) as shown below:  

[tex]f(1)=a\\f(2)=a\,*\,(\frac{3}{2} )\\f(3)=a\,*\,(\frac{3}{2} )^2\\f(4)=a\,*\,(\frac{3}{2} )^3\\f(5)=a\,*\,(\frac{3}{2} )^4[/tex]

Since we are given the information that [tex]f(5)=81[/tex] we can use this to find the value of the first term:

[tex]f(5)=\,a\,*\,(\frac{3}{2} )^4\\81=\,a\,*(\frac{81}{16} )\\a\,*\,81=\,81\.*\,16\\a\,=\,16[/tex]

Notice as well that the first term doesn't contain the common ratio, the second term contains the common ration (3/2) to the power one, the third one contains the common ratio to the power two, the fourth one contains it to the power three, and so forth. So the exponent at which the common ratio appears is always one unit less than the order (x) of the term in question. This concept helps us finalize the expression for the sequence's formula:

[tex]f(x)=16\,*\,(\frac{3}{2} )^{x-1}[/tex]

Answer:

The original price of the computer is $ 6,000  .

Step-by-step explanation:

Given as :

The selling price for the computer = $ 1,500.00

The discount coupon = 75 %

Let the original price or market price of computer = $ x

Now,

Discount % = [tex]\dfrac{\textrm market price - \textrm selling price}{\textrm market price}[/tex] × 100

Or, 75 % = [tex]\dfrac{\textrm x - \textrm 1500}{\textrm x}[/tex] × 100

Or, [tex]\frac{75}{100}[/tex] = [tex]\dfrac{\textrm x - \textrm 1500}{\textrm x}[/tex]

Or, [tex]\frac{1500}{x}[/tex] = 1 - [tex]\frac{75}{100}[/tex]

Or, [tex]\frac{1500}{x}[/tex] = [tex]\frac{100 - 75}{100}[/tex]

Or, [tex]\frac{1500}{x}[/tex] = [tex]\frac{25}{100}[/tex]

Or, x = [tex]\frac{150000}{25}[/tex]

∴  x = $ 6,000

Hence The original price of the computer is $ 6,000  .  answer

Answer:

20/48

Step-by-step explanation:

Answer:

I think it would be 1/4+1/6

Step-by-step explanation:

2/8 can be simplified by 2 because 2 goes into 2 once so 1 and 2 goes into 8, 4 times so that equals 1/4 and I believe the 1/6 is already simplified.

Answer:

50

Step-by-step explanation:

100/2=50

A quarter of something is just another word for a fourth of something (1/4th).

We can solve this using two different ways.

Solution #1:

1/4 = 0.25

200 * 0.25 = 50 (quarter of 200)

Solution #2:

200 / 4 = 50 (quarter of 200)

Answer:

Using [tex]\pi =3.14[/tex] the volume of the cylinder is [tex]1471.875\ m^{3}[/tex]

Step-by-step explanation:

We are using [tex]\pi =3.14[/tex].

We know that volume of a cylinder is [tex]\pi (r)^2h[/tex]

For this we have

Height of the cylinder is given that is [tex]18.75\ m[/tex]

And the radius of the cylinder is unknown,

But there is a hint in which we can see that the diagonal,height and diameter forms a right angled triangle (or a cone).

Where [tex]21.25\ m[/tex] is the hypotenuse.

Using Pythagoras formula.

[tex](Hypotenuse)^2=(base)^2+(perpendicular)^2[/tex]

We can find the value of diameter which is the base over here.

So,

[tex]d=\sqrt{(21.25)^2-(18.75)^2}=\sqrt{(451.56-351.56)}=\sqrt{(100)}=10\ m[/tex]

Then radius [tex]\frac{diameter}{2} =\frac{10}{2}=5\ m[/tex]

Now using the above values and plugging it on to the formula.

Volume [tex]=\pi (r)^2h=(3.14)(5)^2\times 18.75=1471.875\ m^3[/tex]

So the volume of the cylinder is [tex]1471.875\ m^3[/tex]

Answer:

$65 ≤ x ≤ $135

It can also be written as $65 ≤ x AND x ≤ $135

Step-by-step explanation:

Now, one should know the meaning of compound inequality. A compound inequality is the inequality which simply combines the two simple inequalities.

Now, in an inequality, three relations are performed, equal to, less than and greater than. You can combine 'equal to' with 'less than' or 'greater than' according to situation given.

Notice that in given sign

≤

the value at left side or the pointed side will be small or lesser than the value at right side. Also notify that if inverted, like this ≥

Value of left side will be greater. Means the value at pointed side will always be smaller. The lower bar is sign of equal to

if this is written

x ≤ 3

It means that x can be equal to three or any value less than 3 means 2,1,0,-1 etc.

Now in question given, it is stated that money should be not less than $65 means it can either be $65 or more but not less than it. Lets assume 'x' as the amount required,

So one inequality is

$65 ≤ x

For second condition which is amount should be no more than $135, means it can be $135 or less, so inequality is

x ≤ $135

Remember that we use AND in the answer because both statements of inequality are need to be fulfilled or satisfied.

Answer:

m<1: 51

m<2: 61

m<3: 29

Step-by-step explanation:

m<1 = 51, because to find the 3rd angle, you need to add the other two angles and then subtract 180 from that answer.

61 + 68 = 129

180 - 129 = 51

m<2 = 61, because it's a vertical angle, meaning that the angle that's opposite to it exactly, is the same. So since the angle opposite to m<2 is 61, that's what the answer would be.

m<3 = 29, because all you need to do is add 90 and 61, and then subtract 180 by the answer. I got 90 as one of the angle measurements because there's a right triangle, meaning it's 90. Then since we already know what angle 2 is (61) then all you need to do is add:

90 + 61 = 151

Then subtract:

180 - 151 = 29

Answer:

$132 in ratio of 2:3:6 is $24, $36 and $72.

Step-by-step explanation:

Dividing $132 in ratio of 2:3:6

Let share of first be = [tex]2x[/tex]

Share of second will be = [tex]3x[/tex]

Share of third will be = [tex]6x[/tex]

Adding the shares

⇒ [tex]2x+3x+6x=11x[/tex]

Total value = $132

So we have,

[tex]11x=132[/tex]

Dividing both ides by 11.

[tex]\frac{11x}{11}=\frac{132}{11}[/tex]

[tex]x=12[/tex]

∴ First share = [tex]2\times 12=\$24[/tex]

∴ Second share = [tex]3\times 12=\$36[/tex]

∴ Third share = [tex]6\times 12=\$72[/tex]

Mean = -2

Median = -1

Mode = Nil

Range = 38

Step-by-step explanation:

Given data is:

-18, 10, -20, -11, 9, 18

Arranging the data in ascending order

-20, -18, -11, 9, 10, 18

Mean:

Mean is given by the formula

[tex]Mean=\frac{Sum}{items}[/tex]

Items are: 6

[tex]Mean = \frac{-20-18-11+9+10+18}{6}\\= \frac{-12}{2}\\= -2[/tex]

Mode:

Mode is the most frequent value in the data. So,

As there is no value repeated in the data. There is no mode

Median:

Median is the middle value of the data. As the no. of data value are even,

the average of middle 2 values is mode.

Note that the data has to be arranged in ordered to find median

Here,

[tex]Median = \frac{-11+9}{2}\\=\frac{-2}{2}\\= -1[/tex]

Range:

Range is the difference between the largest and smallest value of the data

Here

Largest value = 18

Smallest value = -20

So,

[tex]Range = Largest\ value-Smallest value\\= 18-(-20)\\= 18+20\\=38[/tex]

Hence,

Mean = -2

Median = -1

Mode = Nil

Range = 38

Total distance traveled by Doris during practice is 2875 meters

Step-by-step explanation:

Given

Distance run by Doris = 2.5km

Converting into meters (as the distance has to be added to other distances, all the distances should be in same unit)

2.5*1000= 2500 meters

Distance covered sprinting = 300 meters

distance walked = 1/4 of 300

[tex]=\frac{300}{4} = 75m[/tex]

Hence,

The total distance will be:

[tex]= Distance\ ran+Distance\ sprinted+Distance\ walked\\= 2500+300+75\\=2875\ meters[/tex]

Answer:

Option C.

Step-by-step explanation:

Given information: RSTU is a parallelogram, Digonals RT and SU intersect each other at point V, UV=(x-3) and VS=(3x-13).

According to the properties of a parallelogram, the diagonals of a parallelogram bisect each other.

Using the properties of parallelogram we can say that point V divides the diagonal SU in two equal parts, UV and VS.

[tex]VS=UV[/tex]

[tex]3x-13=x-3[/tex]

Subtract x from both sides.

[tex]2x-13=-3[/tex]

Add 13 on both sides.

[tex]2x=10[/tex]

Divide both sides by 2.

[tex]x=5[/tex]

Therefore, the correct option is C.

Final answer:

The theorems about parallelograms are used in mathematics to find unknown sides or angles and to prove properties of figures. When dealing with vectors, the parallelogram rule for vector addition helps find the resultant by constructing a parallelogram with the vectors as sides and the diagonal as the resultant.

Explanation:

To use theorems about parallelograms to solve problems, we often apply these principles to find unknown sides or angles or to prove certain properties about the figures we are dealing with. For example, one theorem states that opposite sides of a parallelogram are congruent, which can be useful when you need to find the length of a missing side.

Regarding vector addition, the parallelogram rule is applied. According to this rule, if we are adding two vectors, say vector A and vector B, we place them tail to tail, draw the vectors such that they form adjacent sides of a parallelogram, and then the resultant vector is represented by the diagonal of the parallelogram that starts from the common tail of the two vectors.

Similarly, if we need to find the resultant of three or more vectors, we use the parallelogram rule iteratively. We first find the resultant of the first two vectors and then add the third vector to this resultant using the same rule. This process is based on the associative and commutative properties of vector addition.

Answer:

x = -12

Step-by-step explanation:

Set logs up on both sides-

log 16^x = log 64^x+4

The variable goes behind because of the exponent log property (exponents are permitted to go behind the log to multiply)-

x * log 16 = x + 4 * log 64

Divide both logs out-

log 64/log 16 = 1.5

Simplify-

x = x+4(1.5)

1.5x + 6 = x

Remove 1.5-

1 - 1.5 = -.5x

Simplify-

-.5x = 6

Divide both sides-

6/-.5x = -12

Hence, the answer would be -12

Step-by-step explanation:

Here, the given expression to be simplified : -3( y + 3 ) = 2 y + 3

Now, by DISTRIBUTIVE PROPERTY:

A (B +C)  = AB + AC

Simplifying the given expression:

-3( y + 3 ) = 2 y + 3  ⇒  -3 ( y) - 3 ( 3)  = 2 y + 3

or, -3y - 9 =  2y + 3

⇒ 3  y +  2 y = -3  -  9

or, 5 y  = -12   ⇒   y = -12/5  = -2.4

⇒ y = - 2.4

Hence,for the given expression -3( y + 3 ) = 2 y + 3  the simplified value of  y = -2.4
