During the All Stars Skills competition, a puck was launched through the air at a
speed of 41 km/h from a height of 2.5 cm. The algebraic model of the path of the
puck is defined by h = -4.9+ + 41t +0.025, where h represents height in cm and t
represents time in seconds.

1.Construct a table of values for the first 10 seconds of the puck's movement.
Round to 0 decimal places.

2.Using graph paper, graph the data points. Join with a smooth curve. Scan your
graph.

3.Approximately how long before the puck will hit the ice?

4.For what values of time is the height invalid?

Step-by-step explanation:

d= 1- 4bh

Step-by-step explanation:

- 8b = 2d - 2/h

Multiply both sides of the equation by h.

- 8bh = 2d - 2

Swap sides so that all variable terms are on the left-hand side.

2d - 2 = - 8bh

Add 2 to both sides.

2d = - 8bh + 2

The equation is in standard form.

2d = 2 - 8bh

Divide both sides by 2.

2d/2 = 2 - 8bh/2

Dividing by 2 undoes the multiplication by 2.

d = 2 - 8bh/2

Divide -8bh + 2 by 2.

Therefore: d = 1 - 4bh

Answer:

$23.20

Step-by-step explanation:

1 hour of work = $2.90

8 x 2.90 = 23.20

8 hours of work will get an employee $23.20

If they worked 8 hours daily in a week:

7 x 23.20 = 162.40

Working 8 hours every day in a week will get them $162.4

Answer:

Answer:

irrational

Step-by-step explanation:

irrational. An irration number can not be expressed as a fraction or a decimal. This can not because this number goes on forever and it will never end, and you can write a never ending number as a fraction or a decimal. here is a tip to remember if a number never end like pi then it is irrational,

Answer:

The answer is 83°

Step-by-step explanation:

by the sum of iner and outer angle=180°

180-126= 54°

x=180-43+54

x=180-97

x=83°

hope that helped.?<3

Answer:

[tex]3b + 4c = a[/tex]

[tex]3b = a - 4c[/tex]

[tex] \frac{3b}{3} = \frac{a}{3} + \frac{ - 4}{3} [/tex]

[tex] \frac{3b}{3} = \frac{a}{3} + \frac{ - 4c}{3} [/tex]

[tex]b = \frac{a}{3} + \frac{ - 4c}{3} [/tex]

[tex]b = \frac{a}{3} - \frac{4c}{3} [/tex]

Answer:

x >= 12

Step-by-step explanation:

2x + 7 <= 3x - 5

7 + 5 <= 3x - 2x

12 <= X

Answer:

Step-by-step explanation:

1) f(x)=1/3(x+1)^2

so if we use the equation f(x)=a(x-h)^2+k then we can plug in the different things.  a would represent the compress/stretches, so in order to move horizontally, we would need to do 1/3

for h: that is the horizontal translations so, left and right. BUT remember it's the opposite. so if you want to go left <-- you would have to put a + sign and to go right you would have to put a - sign.

I hope that helps it prob is confusing sorry >-<

Answer:

below

Step-by-step explanation:

IF l₁ and l₂ are parallel, then:

Angles 2, 4, 5, 8 all equal 86 degrees

Then angles 1, 6, 3 , 8 all equal 180 - 86 which is 94 degrees

Answer:

20

Step-by-step explanation:

63 - 43 = 20

Answer:

20 students

Step-by-step explanation:

because 43+s=63

63-43=20

s=20

so it have 20 students on the playground

Answer:

12

Step-by-step explanation:

Since this is a right angle triangle, and we have two lengths already found, we can use pythagoras to find x.

We know that

a²+b²=c²

Where a, and b are the smaller lengths (the adjacent and opposite), and C is always the longest one (the hypotenuse).

We want to find x, which in this case is c. So,

to solve for c, we get

c=[tex]\sqrt{a^2+b^2 }[/tex]

So, after plugging in the values, we get

[tex]c=\sqrt{10.6^2+6.1^2}[/tex]

[tex]c=12.23\\\\=12 (rounded)[/tex]

Answer:

[tex] \frac{x + 2}{x - 2} [/tex]

Step-by-step explanation:

This is much easier to solve actually since both expressions have the same denominator.

To solve it therefore,just sum the numerators

(x²-4x-2)+(8x+6)

x²+4x+4 Now divide by the common denominator

x²+4x+4/x²-4

Factorize both numerator and denominator

(x+2)(x+2)/(x-2)(x+2)

Cancel out common terms

x+2/x-2

Answer:

well, 72.7

a÷b is:

9.2159

9.22 (2 DP)

Answer:

b = 0

Step-by-step explanation:

4b + 6 = 2 - b + 4

4b + b = 2 + 4 - 6

5b = 6 - 6

5b = 0

b = 0 / 5

b = 0

Answer:

9.5km/hr and 16.667m/s

Step-by-step explanation:

velocity = Distance / Time

v = 19/2  -->  v = 9.5km/hr

v = 2000m/120s --> v = 16.66666667m/s

Answer:

Step-by-step explanation:

First, you must find the actual decrease in temperature.

Decrease = Yesterday's temperature - Today's temperature

Decrease = 80 - 75

Decrease = 5 degrees

Now, find the percentage decrease.

% Decrease = Actual decrease / Yesterday's temperature x 100

% Decrease = 5/80 x 100

% Decrease = 0.0625 x 100

% Decrease = 6.25 %

So, the percent decrease in high temperature from yesterday to today is 6.25%
