Calvin kicked a soccer ball laying on the ground. It was in the air for 5 seconds before it hit the ground. While the soccer ball was in the air it reached a height of approximately 25 feet. Assuming that the soccer ball’s height (in feet) is a function of time (in seconds), what are the domain and range in the context of this problem?

Answer:

75%

Step-by-step explanation:

Step 1: Build the equation.

Step 2: Simplify.

Step 3: Multiply both sides by 25/16.

Therefore, the missing number is 75 to complete the equation 75% of 64 = 48.

Answer:

If you know what a graph looks like, then it is similar looking if not almost the same. The vertical lines represent what ever your x value is, in example the number of toys you have to how much they cost(ed) your x value would be the number of toys you have.

Step-by-step explanation:

Answer: a bar plot is a type of graph. The vertical lines shows the amount/data.

The way most teachers show this is with what people prefer like, favorite color, food, etc...

Step-by-step explanation:

Step-by-step explanation:

I guess we are only talking about quadratic functions/equations here.

the world is not unified regarding what is the standard form of a quadratic equation.

but let's assume your teacher means

standard form

f(x) = y = ax² + bx + c

vertex form

f(x) = y = a(x - h)² + k

so, we are using the provided x, y coordinates to get a, b and c.

3.75 = a×0.125² + b×0.125 + c

3 3/4 = a×(1/8)² + b×(1/8) + c

15/4 = a/64 + b/8 + c

15×16/64 = a/64 + 8b/64 + 64c/64

=> 240 = a + 8b + 64c

4 = a×0.25² + b×0.25 + c

4 = a×(1/4)² + b×(1/4) + c

4 = a/16 + b/4 + c

4×16/16 = a/16 + 4b/16 + 16c/16

=> 64 = a + 4b + 16c

3 = a×0.5² + b×0.5 + c

3 = a×(1/2)² + b×(1/2) + c

3 = a/4 + b/2 + c

3×4/4 = a/4 + 2b/4 + 4c/4

=> 12 = a + 2b + 4c

we have now from the third equation

a = 12 - 2b - 4c

we put this into the second equation

64 = (12 - 2b - 4c) + 4b + 16c = 12 + 2b + 12c

32 = 6 + b + 6c

26 = b + 6c

b = 26 - 6c

and therefore

a = 12 - 2(26 - 6c) - 4c = 12 - 52 + 6c - 4c = 2c - 40

this a and b we use now in the first equation

240 = (2c - 40) + 8(26 - 6c) + 64c =

= 2c - 40 + 208 - 48c + 64c = 18c + 168

72 = 18c

c = 4

b = 26 - 6×4 = 26 - 24 = 2

a = 12 - 2×2 - 4×4 = 12 - 4 - 16 = -8

so, the standard form is

f(x) = y = -8x² + 2x + 4

the vertex form

we get this by transforming the standard form.

e.g. by competing the square :

y - 4 = -8x² + 2x = -8(x² - x×1/4)

y - 4 -8×(1/8)² = -8(x² -x×1/4 + (1/8)²)

y - 4 - 8/64 = -8(x - 1/8)²

y - 32/8 - 1/8 = -8(x - 1/8)²

y - 33/8 = -8(x - 1/8)²

y = -8(x - 1/8)² + 33/8

We are finding slope:

change in y / change in x

277 - 205 / 2007 - 1997

72 / 10

Answer:

∠ PQR = 150°

Step-by-step explanation:

∠ PQR = ∠ PQS + ∠ SQR , substitute values

12x - 6 = 16 + 9x + 17

12x - 6 = 9x + 33 ( subtract 9x from both sides )

3x - 6 = 33 ( add 6 to both sides )

3x = 39 ( divide both sides by 3 )

x = 13

Then

∠ PQR = 12x - 6 = 12(13) - 6 = 156 - 6 = 150°

Answer:

m<PQR = 150°

Step-by-step explanation:

<PQR = (12x-6)°

<SQR = (9x+17)°

<PQS = 16°

find m<PQR.

since <SQR + <PQS = <PQR,

then (9x+17)° + 16° = (12x-6)°

combine like terms;

9x + 17 + 16

9x + 33 = 12x - 6

subtract 33 from both sides;

9x = 12x - 39

subtract 12x from both sides;

-3x = -39

divide by -3;

x = 13, then input x into the equation for m<PQR;

m<PQR = (12x-6)°,

(12(13)x - 6)°

(156 - 6)°

Answer: 150°

Answer:

60

Step-by-step explanation:

90x + 270= 5670

90x=5670-270

x=5400÷90

x=60

Answer:

x = 60

Step-by-step explanation:

1) 100x - 10x + 270 = 5670

2) 100(60) - 10(60) + 270 = 5670

3) 6000 - 600 + 270 = 5670

4) 5400 + 270 = 5670

5) 5670 = 5670

All I really did was input random numbers for the value of "x", then add 270 at the end of an equation. If that method works for me, it should work for everyone, including you.

The single transformation that took place from their starting position to their final destination is (x, y) ⇒ (x + 7, y)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Translation is the movement of a point either up, down, left or right in the coordinate plane.

Answer:

B) 3x - 4y = 20

Step-by-step explanation:

We can eliminate C and D since 4(0) + 3(-5) = -15 (not 20) and 4(0) - 3(-5) = 15 (not -20)

Now we will determine the slopes for A and B to see which one is correct:

A) 3x + 4y = -20 -> 4y = -20 - 3x -> y = -5 - 3/4x -> y=-3/4x - 5 (not right)

B) 3x - 4y = 20 -> -4y = 20 - 3x -> y = -5 + 3/4x -> y = 3/4x - 5 (right)

Therefore, B is correct since the slope is 3/4 and passes through (0,-5)

Based on the number of days that Maggie swam and the distance swam everyday, Maggie swam 13.16km

Maggie swam 940 meters each day. She did this for two weeks. The total distance she swam is:

= 940 x 2 x 7 days a week

= 13,160 meters

A meter is 0.001km so 13,160 meters in kilometers would be:

= Number of meters x Conversion factor

= 13,160 x 0.001

= 13.16 km

In conclusion, Maggie swam 13.16 km.

Given that 1/(7+5√2)

We know that

The Rationalising factor of a+√b is a-√b

The denominator = 7+5√2

The Rationalising factor of 7+5√2 is 7-5√2

On Rationalising the denominator then

=> [1/(7+5√2)]×[ (7-5√2)/(7-5√2)]

=> [1×(7-5√2)]/(7+5√2)(7-5√2)]

=> (7-5√2)/[(7+5√2)(7-5√2)]

=> (7-5√2)/[7²-(5√2)²]

Since , (a+b)(a-b) = a²-b²

Where , a = 7 and b = 5√2

=> (7-5√2)/(49-50)

=> (7-5√2)/(-1)

=> -7+5√2

=> 5√2-7

3).

Given that (x-2)³

This is in the form of (a-b)³

Where, a = x and b = 2

We know that

(a-b)³ = a³-3a²b+3ab²-b³

=> (x-2)³ = x³-3(x²)(2)+3(x)(2)²-2³

=> (x-2)³ = x³-6x²+12x-8

The coefficient of x² is -6
