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

Answer:

D. Lines e and f are parallel because their same side exterior angles are supplementary.

Step-by-step explanation:

I know for a fact that it is not C or A even though those ones would make the most sense. This leaves B and D; It's not B because is said that angles A and B are both exterior which is incorrect, A in interior and B is Exterior. This leaves us with D as our final answer.

Hope this helps, may I get brainliest please? :)

The parallel lines are; Lines e and f are parallel because their same side exterior angles are supplementary.

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the given parallel line has equation y = 4x + 2, thus its slope is 4 and thus, the slope of the needed line is 4.

We have given that Lines e and f are intersected by lines a and b.

At the intersection of lines a and e, the uppercase right angle is 110 degrees. The lines b and e, the uppercase right angle is 110 degrees. The lines b and f, the bottom right angle is 80 degrees.

Therefore, The parallel lines is; Lines e and f are parallel because their same side exterior angles are supplementary.

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.

Answer:

Answer:

0.5 pounds - 1 bag

4.5 pounds - x bags

[tex]x = \frac{4.5}{0.5} = 9[/tex]

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
