Answer:

11

Step-by-step explanation:

it has a vertex at (2,11)

.

f(2) = 11

how to find the vertex;

function equation is f(x) = ax^2 + bx + c

we can find x by :-b/2a, -8/-4 = 2

and by putting the x value we get the y

f(2) = 11

Answer:

11

Step-by-step explanation:

x= -b/2a

x= -8/2(-2)

x=-4/-2

x=2

f(2) = -2(2) +8(2)+ 3

f(2) = -8 +16 + 3

f(2) = 11

Maximum value is 11

In the diagram, angle 1 = 4x + 30, and angle 3 = 2x +48.
iragen [17]

Answer:

Since we have the information for Angles 1 and 3, and they are vertical, we can set them equal to each other. Once we have done this we can find the measures of them combined, and subtract it from 360 in order to only have the measure of 2 and its vertical angle. Finally, all we need to do now is divide the remaining measure by 2, and this will give us the measure of angle 2.

Angle 1=Angle 3

4x+30=2x+48

2x+30=48

2x=18

x=9

Angle 1=4(9)+30

Angle 1=36+30

Angle 1=66

Angle 1=Angle 3

Angle 1+ Angle 3=132

360-132=228

228/2=114

Angle 2= 114

N/8= 25/40<br> N/20=85/100<br> 2/3=16/n<br> 5/6=25/n
4vir4ik [10]
N/8 = 25/40
40n = 25 * 8
40n = 200
n = 200/40
n = 5

n/20 = 85/100
100n = 85 * 20
100n = 1700
n = 1700/100
n = 17

2/3 = 16/n
2n = 16 * 3
2n = 48
n = 48/2
n = 24

5/6 = 25/n
5n = 25 * 6
5n = 150
n = 150/5
n = 30
