1. F(3)= -2(3)-5

-6-5

F(3)=-11

2. F(3)= -2(3)^2-4

-6^2-4

36-4

F(3)=32

3. F(x)=−2x−5

For: x=−2, f(x) is:f(−2)=(−2×−2)−5=4−5=−1

For: x=−1, f(x) is:f(−1)=(−2×−1)−5=2−5=−3

For: x=1, f(x) is:f(1)=(−2×1)−5=−2−5=−7

For: x=2, f(x) is:f(2)=(−2×2)−5=−4−5=−9

The Range is:

{−1,−3,−7,−9}

4. -80, -110

Radda [10]

Answer:

y=-3x+4

Step-by-step explanation:

im assuming that you need the equation of the table

to find slope, y2-y1/x2-x1    10-4/-2-0

6/-2=-3   slope=-3  

y=mx+b   just sub in the numbers from a point in the table

10=-3(-2)+b

10=6+b

b=4

y=-3x+b

2 planes leave the airport at the same time. their speeds are 140 mph and 170 mph and the angle between their courses is 25 degr
Damm [24]

Answer:

183.27miles

Step-by-step explanation:

Note that we are considering two planes.

Plane 1

Speed = 140 mph

Time = 2.5 hours

Distance = ?

Speed = distance/time

140 mph = distance/2.5hrs

Distance = 140×2.5

= 350miles

Plane 2

Speed = 170 mph

Time = 2.5 hours

Distance = ?

Speed = distance/time

170 mph = distance/2.5hrs

Distance = 170×2.5

= 425miles

The angle between side is 25 degree

From cosine rule

c^2 = a^2 + b^2 − 2abcos(tetha)

Where a = 350

b = 425miles

c^2 = 350^2+425^2-2(350×425)(cos25)

c^2 = 122500+180625-297500(0.906)

c^2 = 303125-269535

c^2 = 33590

C = √33590

C = 183.27miles

The distance they flew apart after 2.5hrs is 183.27miles
