Help plz. I don't understand

Mathematics
1 answer:
stiv31 [10]3 years ago
7 0

Answer:

Step-by-step explanation:

The illustration is unclear. Is y the base of both triangles, or is it the base of the triangle on the right?

I'll assume that y is the base of the triangle on the right.

The triangle on the left is a 45-45-90 triangle. The lengths of the sides are in the ratio 1:1:√2, so the length of the vertical leg is 8/√2.

The triangle on the right is a 30-60-90 triangle. The lengths of the sides are in the ratio 1:√3:2.

The side opposite the 30° angle is 8/√2, so the side opposite the 60° angle is 8√3/√2 = 4√6, and the side opposite the 90° angle is 2×8/√2 = 8√2.

earnstyle [38]
For the first part 55,202+41,807+31,367+15,970+8,626+4,995 and that equals 157967$ now you have to divide that amounts by the total number of salaries so 157967 divided by 6 that equals 26327.83$

If f(x)=2x^2+3x−4, and g(x)=−8x−4, what does f(x)+g(x) equal?
padilas [110]

Answer:

f(x) + g(x) = 2x² - 5x - 8 ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- We can add to functions by adding the like terms in them

∵ f(x) = 2x² + 3x - 4

- f(x) is a quadratic function because the greatest power of x is 2

∵ g(x) = -8x - 4

- g(x) is a linear function because the greatest power of x is 1

∵ f(x) + g(x) means (f + g)(x)

∴ f(x) + g(x) = (2x² + 3x - 4) + (-8x - 4)

- Add the like terms

∵ 3x + -8x = -5x

∵ -4 + -4 = -8

∴ f(x) + g(x) = 2x² + -5x + -8

- Remember (+)(-) = (-)

∴ f(x) + g(x) = 2x² - 5x - 8

* f(x) + g(x) = 2x² - 5x - 8
