Answer:
hello your answer will be 9/2
It depends on how many Popsicle sticks you are going to use.So, for example, say that you are using 5 Popsicle sticks for the model. What you do is 15.2 x 5, 15.2 being the height of the sticks and 5 for the number of sticks you are using. The answer will be 76 cm tall. 21 15.2 x 5 --------- 76.0
5 - 2 = 3
3 x ? = 24
(24 ÷ 3 = 8)
3 x 8 = 24
To simplify, we can use the FOIL method. That stands for first, outer, inner, last. What we do is take two factors at a time and multiply the first terms by each other, the outer terms together, etc.
Let's start with (2x-1) and (x+5)
First: 2x * x = 2x^2
Outer: 2x * 5 = 10x
Inner: -1 * x = -x
Last: -1 * 5 = -5
2x^2 + 9x - 5
Now FOIL this result with (3x - 2)
6x^3 - 4x^2 + 27x^2 - 18x - 15x + 10
Simplify:
6x^3 - 23x^2 - 33x + 10
Sin = opposite / hypotenuse
sin x° = 4/6
x° = sin^-1 (4/6)
x = 41.81° (nearest tenth)
Hope this helps!
