Answer:

nice question...

so here we go

3^ -x = 1 / 3^x

so 1/ 3^x = 2 so 3^x = 1/2

we can write 3^2x as 3^x multiplied by 3^x right?..(law of exponents)

recall that 3^x =1/2

so now according to question we have to find the value of 3^2x =  1/2 * 1/2 = 1/4

Step-by-step explanation:

The given expression is an application of an exponential equation. The result shows that [tex]3^{2x} = \frac{1}{4}[/tex] if [tex]3^{-x}=2[/tex]

Given that [tex]3^{-x}=2[/tex]

This can also be expressed as [tex]\frac{1}{3^x} =2\\[/tex]

Cross multiply

[tex]\frac{1}{3^x} =2\\3^x = \frac{1}{2}[/tex]

Take the square root of both sides

[tex](3^x)^2 = (\frac{1}{2} )^2\\3^{2x} = \frac{1}{4}[/tex]

The result shows that [tex]3^{2x} = \frac{1}{4}[/tex] if [tex]3^{-x}=2[/tex]

Answer:

Least to greatest is 81/10, 8 1/9, 8.115 and 9.95

Step-by-step explanation:

Answer:

See below.

Step-by-step explanation:

1) 4x + 8 = 2x + 10

2x = 2

x = 1

2) 9y - 3 = 6y + 12

3y = 15

y = 5

3) 8m + 4 =  4m - 20

4m = -24

m = -6

4) 11z - 14 = 5z + 4

6z = 18

z = 3

5) 3q - 6 = 8q - 6

5q = 0

q = 0  

6) 20n + 7 = 6n - 21

14n = -28

n = -2  

7) 2w - 8 = 7w - 3

5w = -5

w = -1

Step-by-step explanation:

Given:

Total students = 6,000

Students taking honors courses = 1,500

Students preferring basketball = 1,800

Students in both = 450

To find:

Whether the two events "taking honors courses" and "preferring basketball" are independent or not?

Solution:

Let as consider the following events.

A : Taking honors courses

B : Preferring basketball

[tex]A\cap B[/tex] : Both

We know that,

[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

Using this formula, we get

[tex]P(A)=\dfrac{1500}{6000}=0.25[/tex]

[tex]P(B)=\dfrac{1800}{6000}=0.30[/tex]

[tex]P(A\cap B)=\dfrac{450}{6000}=0.075[/tex]

Two evens are independent if

[tex]P(E_1\cap E_2)P(E_1)\cdot P(E_2)[/tex]

Now,

[tex]P(A)\cdot P(B)=0.25\times 0.30[/tex]

[tex]P(A)\cdot P(B)=0.075[/tex]

[tex]P(A)\cdot P(B)=P(A\cap B)[/tex]

So, the events A and B are intendent because

[tex](\dfrac{1500}{6000})(\dfrac{1800}{6000})=\dfrac{450}{6000}[/tex]

Therefore, the correct option is D.

Answer:

Letter B is the answer.

Step-by-step explanation:

B is the answer because you would want to rotate figure EFD to PQR, where line DE would line up with PR.

A is not correct because a translation would not line up the lines or points. Triangle DEF is facing in a different direction as PQR.

C is not correct because it is only being reflected once and the line upon where it is being reflected wouldn't match up with the triangle PQR. EF would not be able to mapped onto line QR because of the line it is being reflected upon.

D is not correct for the same reason as A, which is because a translation would not line up the lines or points. Triangle DEF is facing in a different direction as PQR.

E gets close because of it being rotated, but it is incorrect since line DF wouldn't match up with line PQ. PQ is only congruent to line EF.

Answer:

70 feet

Step-by-step explanation:

A kite is flying 30 feet from a stop sign

The child flying the kite is standing 40 feet from the stop sign

Therefore the length of the string from the child to the kite can be calculated as follows.

= 30 feet + 40 feet

= 70 feet

Answer:

50 feet

Step-by-step explanation:

It's supposed to be 30x30= 900, 40x40= 1'600

900+1600=2500. 2500 square rooted= 50

the answer is 50

so sorry to say but ritmeks you're wrong, you don't add them together you multiply them by themselves then add both together then you square root the answer you get from that

Answer:

y + 4 = - (x - 5)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 1 and (a, b) = (5, - 4) , then

y - (- 4) = - 1 (x - 5) , that is

y + 4 = - (x - 5)

Answer:

[tex]y+4=-(x-5)[/tex]

Step-by-step explanation:

Point-slope form equation is written as:

[tex]y-y_1=m(x-x_1)[/tex]

where m is the slope and [tex](x_1,y_1)[/tex] is the point which the line passes through  so to to find the equation of line which passes through the point

(5 , -4) it means the point should satisfy the equation which furthermore means that the point lies on the lie so we can replace y1 with -4 and x1 with 5 and since we have m = -1 we can thus find b and rewrite the equation like this:

[tex]y-y_1=m(x-x1)\\y-(-4)=-1(x-5)\\y+4=-x+5[/tex]

since we need it point-slope form we leave it like this

[tex]y+4=-(x-5)[/tex]

Answer:

The answer is x=2

Step-by-step explanation:

8(4-x)=7x+2

32-8x=7x+2

-8x+32=7x+2

8x+32-7x=7x+2-7x

-15x+32=2

-15x+32-32=2-32

-15x=-30

-15x/-15=-30/-15

x=2

Answer:

2

Step-by-step explanation:

First, do the distributive property: 32-8x =7x+2

Next, get the variable to one side: 32-8x(-7x)=7x(-7x)+2

Then, subtract 32 from both sides to isolate the variable: -15x+32(-32)=2(-32)

Finally, we divide -30 by -15 : -15x= -30  

x= 2

Answer:

B. $27,000

Step-by-step explanation:

Given that:

The base price of a car = $24300

The air conditioning costs = $725

The leather interior costs = $1225

Installation of four heated seats cost = $945

if we round each entity of item purchased to the nearest thousand, Then:

The base price of a car ≅ $24000

The air conditioning costs ≅ $1000

The leather interior costs ≅ $1000

Installation of four heated seats cost ≅ $1000

So, the total estimate = 24000 + 1000 + 1000 + 1000 = $27000

= $27000  to the nearest thousands

Answer:

x is 10

Step-by-step explanation:

For a parallelogram, the sum of adjacent angles equals 180 degrees. Based on the given shape, mZBAD and <CBA are adjacent to each other

Hence mZBAD + mZCBA = 180

83 + 9x + 7 = 180

90 + 9x = 180

9x = 180-90

9x = 90

x = 90/9

x = 10

Hence the value of x is 10

Answer:

The difference in elevation of the two towns is 3182 feet.

Step-by-step explanation:

Let's treat the elevation of sea level as 0 feet. That way, we can calculate the elevation of the two spots by using it as a measuring parameter.

Apple Valley is 2,900 feet above sea level. Hence, its elevation is (0 + 2,900) feet, which is 2,900 feet.

Death Valley is 282 feet below sea level. Hence, its elevation is (0 - 282) feet, which is -282 feet.

Hence, to calculate the difference, we subtract the elevation of Death Valley from that of Apple Valley, getting [2900 - (-282)] feet, which equals to (2900 + 282) feet which is 3182 feet.

Therefore, the difference in elevation of the two towns is 3182 feet.

Answer:

add them together and set them equal to 180

Step-by-step explanation:

They are both supplementary angles, so 15x+85+20x-10=180, so combine like terms=>35x+75=180

subtract 75 from both sides=>35x=105

divide both sides by 35 to get x alone=>x=3

plug that in for 20x-10

20(3)-10
