How can you determine whether a function is odd or even from the formula of the function?
Liula [17]
F(x) = f(-x) is even, and f(-x)=-f(x) is odd. to know if it's even or odd you take the function and plug in -x for x then simplify it. if it's the same function that you started with , it's even. for example
if you have this
f(x) = -3x^2+4
plug in -x for x which will turn out to be
f(-x) = -3(-x)^2+4
and when simplified it'll be
-3x^2+4 because (-x)^2 is (-x)(-x) which is a positive.
because it's the same, it's an even one.

PLEASE HELP!!<br> Solve for y<br> a) 8<br> b) 12<br> c) 3V7<br> d) 4V7
Arlecino [84]

Answer:

C. y = 3\sqrt{7}

Step-by-step explanation:

Based on the right triangle altitude theorem, the altitude, y, in the diagram above, equals the geometric mean of 9 and 7.

This implies => y = \sqrt{9*7}

Thus, solve for y.

y = \sqrt{9} * \sqrt{7}

y = 3\sqrt{7}

The answer is C. y = 3\sqrt{7}

The slope-intercept form of the equation of a line that passes through (-5,-1) and (10,-7) is y+7=-2/5(x - 10). What is the stan
wariber [46]

Answer:

2x + 5y = -15  OR 2x + 5y + 15 = 0  Not sure they want it equal to zero

Step-by-step explanation:

y + 7 = -2/5(x - 10)

y + 7 = -2/5 x + 4

2/5x + y =-3

5(2/5 x + y = - 3)

2x + 5y = - 15

OR

2x + 5y + 15 = 0

BC=<br> Round your answer to the nearest hundredth.
mrs_skeptik [129]

Answer:

BC ≈ 1.71

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos70° = \frac{adjacent}{hypotenuse} = \frac{BC}{AB} = \frac{BC}{5}

Multiply both sides by 5

5 × cos70° = BC , thus

BC ≈ 1.71 ( to the nearest hundredth )
