75% of 20 = 15

Given f(x) = 4x - 3 and g(x) = 7x +5, find f(x) + g(x).
raketka [301]

Answer:

Given f(x) = 2x + 3 and g(x) = –x2 + 5, find (g o f )(x).

(g o f )(x) = g( f(x))

   = g(2x + 3)

   = –(           )2 + 5    ... setting up to insert the input

   = –(2x + 3)2 + 5

   = –(4x2 + 12x + 9) + 5

   = –4x2 – 12x – 9 + 5

   = –4x2 – 12x – 4

Jorge wants to draw a conclusion about the possible expected values of rolling a 2 on a standard die for different numbers of ro
spin [16.1K]
<span>may result in an expected value that is even, odd, or a decimal.</span> The expected value is equal to the product of the theoretical probability of rolling a 2 on 1 die roll, or <span>1/6</span>, and the number of die rolls. A total of 300 rolls gives an expected value of 50, which is even. A total of 200 rolls gives an expected value of 33.3, which is a repeating decimal. A total of 30 rolls gives an expected value of 5, which is odd.

How would I do this plz help
kari74 [83]

Answer:

273 m^2

Step-by-step explanation:

Firstly, you should find the area of the triangle. Remember that the formula for a triangle's area is (Base x Height) ÷ 2

Therefore,

11 x 14 is 154

154/2 = 77 m^2

Then, we find the area of the square which is just Base x Heigh

14 x 14 is 196m^2

And finally, we just add the two

77 + 196 = 273 m^2

The reason it's not m^3 is because we're not dealing with a third dimensional figure.

Btw, ^ means to the power of.
