The frame of film is actually 50 mm high, but it looks 16 m high on the screen.

Remember that 1 m = 1,000 mm.

So everything looks (16,000)/(50) = <u>320 times</u> as big on the screen
as it is on the film. That's called the scale factor.

The penguin is 35 mm high on the film. He'll look 320 times bigger on the screen.

(320) x (35 mm) = 11,200 mm = <u>11.2 meters</u> high

What equation results from completing the squre and then factoring x^2+10=15
nlexa [21]

For this case we must complete squares:

x ^ 2 + 10x = 15

We add the square of half the coefficient of the term "x",

(\frac {b} {2a}) ^ 2 on both sides of the equation:

x^2+10x+(\frac {10} {2 (1)}) ^ 2 = 25 + 15\\x ^ 2 + 10x + 5 ^ 2 = 25 + 15

According to the perfect square trinomial we have:

(a + b) ^ 2 = a ^2 + 2ab + b ^ 2

Rewriting the expression we have:

a = x\\b = 5\\(x + 5) ^ 2 = 25 + 15\\(x + 5) ^ 2 = 40

ANswer:

(x + 5) ^ 2 = 40

Please help with this!!
Harrizon [31]

Answer:

  1 |   2 |     3 |    4  |    5 |     6 |     7 |    8 |     9 |    10 |     11 |    12

68 | 86 | 104 | 122 | 140 | 158 | 176 | 194 | 212 | 230 | 248 | 268

Step-by-step explanation:

Ok so, the top part of the table is probably going to be the number of months. The cost of the video streaming is linear and follows the equation

cost = 18*cost per month + initial cost

or

cost = 18(number of months) + 50

Using  the table which they gave, enter the number of months at the top, and enter the cost at the bottom. I've gaven the answer already. The months go to welve, and the answer goes into the bottom.

Comment on my answer if it doesn't make sense.

Thank You!
