PLEASE HELP! (see attached image) The equation of function h is h(x) = 1/2(x-2)^2. The table shows some of the values of functio
Mkey [24]

Answer:

A: -4

B: 4

C: m(x)<h(x) for every x, t.e m(x)>h(x) cann’t be treu for any value of x.

Step-by-step explanation:

I’m not sure what is fubction m. I will suppose it is linear function.

For example m(x)=x/2-2.

Part A: h(4)-m(16)=1/2(4-2)^2 - 16/2-2=2-6=-4

Part B: y-intersection on h(x), we find how is h(0). So h(0)=1/2(0-2)^2=2.

For m(x), m(0)=0/2-2=-2. So their y-intersections are fare away 4. (See photo)

Part C: First we chak if there any intersection between h and m.

1/2(x-2)^2=x/2-2, si we have

x^2-4x+4-x+4=0

X^2-5x+8=0,

D=5^2-4*8=25-32<0, so m and h don’t have intersection, and from graph we can see that for every value of x, m(x) will always be less than h(x).

Photo: blue is h(x), green is m(x)

Nata [24]

Answer:

6.519801752°

Step-by-step explanation:

Let θ represent the angle of depression

tanθ=40/350

θ=tan^-1(40/350) *tan^-1 means inverse tan*

θ=6.519801752°

Multiply (9 − 4i)(2 + 5i).
lara [203]

Answer:

38 + 37i

Step-by-step explanation:

(9 − 4i)(2 + 5i)

FOIL

first: 9*2 = 18

Outer: 9*5i = 45i

inner: -4i * 2 = -8i

last : -4i * 5i = -20i^2 = -20(-1) = 20

Combine together

18+45i-8i +20

38 + 37i
