Input 7 for every x so
f(7) = -2 (7)^2 +4
f(7) = -2(49) +4
f(7) = -98 +4
f(7) = -94
Answer:
104degrees
Step-by-step explanation:
From the given diagram, line LJ bisects KN, hence arcKL = arcHJ
Given
arHJ = 4x
arc KJ = x+39
Equating both
4x = x+39
4x - x = 39
3x = 39
x = 39/3
x = 13
Since arcHK = arcHJ + arcKJ
arcHK = x+39+4x
arcHK = 5x+39
arcHK = 5(13) + 39
arcHK = 65+39
arcHK = 104degrees
Hence the measure of arcHK is 104degrees
Answer:
relationship between base and hypotenuse is given by cos angle
let angle be ø
cos ø=b/h
cosø=28/34
ø=cos-¹(28/34)=34.5°
17% are lions, 3/10 = 30% are zebras, therefore the remaining 100 - 47 = 53% of animals are tigers.
Value of the boat after 9 years= 12050*(1-0.12)^9
=$3814(correct to nearest integer)
