A cheetah can run at its top speed for about 25 seconds. Complete the table to represent a cheetah running at a constant speed. explain your reasoning

Hurry please I need it ASAP!!

Answers

x = 650 + 60t

The cheetah must arrive at the same place at the same time:

x = 90t

650 + 60t = 90t

30t = 650

t = 650/30 ≅ 21.7 s

It takes the cheetah a little more than 20 s running at 90 ft/s to reach the moving antelope, so assuming the antelope can maintain its speed of 60, it is safe.

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 = Distance/Time = kWhen distance = 120m, time = 4secs

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

what is 1 +1 pls HELP

Answers

Answer:

2

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.

A. Write an expression to represent the difference between the two points shown on the number line.

B. Find the distance between the two points. [Hint: Remember that distance is always positive.]

Answers

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 expression of the distance

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|

Evaluate the expression

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
