If 3^x=8 what does 3^-2x equal

Answer:

Step-by-step explanation:

Answer:

A. Multinomial population

Explanation:

A multinomial population has categorical data. In other words data in this form has different classes in which data is grouped into. These classes do not overlap and are more than two as opposed to binomial populations that have just two outcome variables or data categories. For example in the above data, we see that data is grouped into three categories:students in business college, students in liberal art college and students in education college

Using the point-slope form:

⇒ [tex](y-y0) = m(x-x0)[/tex]

Which require one point (x0,y0) on the line and the slope (m)

Thus let us plug int the value

[tex](y + 2) = 0(x + 4)\\y + 2 = 0\\y = -2[/tex]

Thus the equation of the line is y = -2

Answer:

x= 31 degrees

Step-by-step explanation:

122x2=244

360-244 = 116

116/2 = 58

z= 91 degrees

so the inside next to corner b is 58 degrees

91 + 58 = 149

180 - 149 = 31

x = 31

Answer:

The answer is D. 216 [tex]in^{3}[/tex]

Step-by-step explanation:

I took the test. Hope this helps.

The volume of the container is 216 inches³.

Volume of a three dimensional shape is the space occupied by the shape.

Given a container.

A triangular prism consists of two triangular bases and three rectangular faces.

The given container is a right triangular prism.

Volume of a triangular prism = Base area × Length of the prism.

Base area = Area of right triangle

                 = [tex]\frac{1}{2}[/tex] × 6 × 8

                 = 24 inches²

Length of the prism = length between the base triangles = 9 inches

Volume = 24 × 9 = 216 inches³

Hence the required volume of the container is 216 inches³.

Answer:

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Because if 2 angle of a triangle are equal the 3rd ones will be equal, since the sum of the angles of the triangle is 180

Part A

distance of point 1 = -1.6

distance of point 2 = 0.3

difference: -1.6 - 0.3 = -1.9

distance: 0.3-(-1.6) = 1.9

The expression that represents the distance between the two points is |0.3 + 1.6| and the distance between the two points is 1.9 units

The points on the line are represented as:

Point 1 = 0.3

Point 2 = -1.6

The distance between the two points is calculated using the following absolute value equation

d = |Point 1 - Point 2|

Substitute the known values

d = |0.3 - -1.6|

This gives

d = |0.3 + 1.6|

Hence, the expression that represents the distance between the two points is |0.3 + 1.6|

In (a), we have:

d = |0.3 + 1.6|

Evaluate the sum

d = |1.9|

Remove the absolute sign

d = 1.9

Hence, the distance between the two points is 1.9 units

Answer:

Step-by-step explanation:

Subject: Re: Need the math proof for 1 + 1 = 2

The proof starts from the Peano Postulates, which define the natural

numbers N. N is the smallest set satisfying these postulates:

P1. 1 is in N.

P2. If x is in N, then its "successor" x' is in N.

P3. There is no x such that x' = 1.

P4. If x isn't 1, then there is a y in N such that y' = x.

P5. If S is a subset of N, 1 is in S, and the implication

(x in S => x' in S) holds, then S = N.

Then you have to define addition recursively:

Def: Let a and b be in N. If b = 1, then define a + b = a'

(using P1 and P2). If b isn't 1, then let c' = b, with c in N

(using P4), and define a + b = (a + c)'.

Then you have to define 2:

Def: 2 = 1'

2 is in N by P1, P2, and the definition of 2.

Theorem: 1 + 1 = 2

Proof: Use the first part of the definition of + with a = b = 1.

Then 1 + 1 = 1' = 2 Q.E.D.

Note: There is an alternate formulation of the Peano Postulates which

replaces 1 with 0 in P1, P3, P4, and P5. Then you have to change the

definition of addition to this:

Def: Let a and b be in N. If b = 0, then define a + b = a.

If b isn't 0, then let c' = b, with c in N, and define

a + b = (a + c)'.

You also have to define 1 = 0', and 2 = 1'. Then the proof of the

Theorem above is a little different:

Proof: Use the second part of the definition of + first:

1 + 1 = (1 + 0)'

Now use the first part of the definition of + on the sum in

parentheses: 1 + 1 = (1)' = 1' = 2 Q.E.D.

Find the required table attached

Since the speed of the Cheetah is constant, this means that the speed must be the same all through in the table.

To get the unknown time and distance, we will have to use the formula below:

Speed = 120/4 = k

Speed = 30m/s = k

We are to get the distance when the time is 25secs

Speed = Distance/Time

30 = d₂/25

d₂ = 30 × 25

d₂ = 750 m

To get the time in the third column

Time = Distance/Speed

t₃ = 270/30

t₃ = 9seconds
