Let a = longest side      
let b = shortest side
let c = third side

P = 14.5                     
a = 6.2
b = 1/2(a)

P = a + b + c
P = 6.2 + 3.1 + c        

P = 9.3 + c                

14.5 = 9.3 + c           
c = 14.5 - 9.3          
c = 5.2

A farmer needs 3x2 − 4x + 10 seeds for each of x3 + 5x − 20 fields. What expression would represent the seeds the farmer needs t
Fittoniya [83]

Answer:

Step-by-step explanation:

(3x^2-4x+10)(x^3+5x-20) =3x^5-4x^4+25x^3-80x^2+130x-200

x=1 is not a good value since when you plug it in you get -126 and you can't have a negative number of seeds.

ppositional angle closure in eyes with narrow angles: comparison between the fellow eyes of acute angle-closure glaucoma and nor
skad [1K]

Here is the comparision

Purpose:To compare the topologic features of acute primary angle-closure glaucoma eyes before an attack to those of normotensive eyes, assuming that untreated fellow acute primary angle-closure glaucoma eyes are candidates for an acute attack.

Methods:Under dark-room conditions, ultrasound biomicroscopy was used to examine 50 eyes (12 fellow eyes of acute primary angle-closure glaucoma and 38 normotensive cases with a closure-possible narrow angle). Before any surgical or laser intervention, all eyes were examined and found to have normal pupillary response without the use of any topical drugs. Each eye was examined at four predetermined angle locations. The chamber angle configuration parameters were measured and compared between the two groups.

Result:Appositional angle closures were detected in 27 fellow eyes and 48 normotensive eyes with a closure-possible narrow angle. The incidence differed statistically between the two groups (69.2% in fellow eyes and 48% in normotensive eyes). In the fellow eye group, appositional angle closures beginning at the angle's entrance were more frequently detected. The distance between the iris root and the bottom of the angle varied significantly between groups.

Conclusion:Acute primary angle-closure glaucoma fellow eyes have different topologic features than normotensive narrow-angled eyes, as well as a higher incidence of appositional closure, which may predispose these eyes to an impending acute attack.

Find the equation of the line that is parallel to y=3x-2 and contains the point (2,11).
SOVA2 [1]

Answer:

y - 11 = 3 (x - 2)

Step-by-step explanation:

This is in point slope form, that is by far the best form to be in. Point slope form is best when there is a point and it gives it to you in slope intercept form. you take the slope from the original equation and stick it into y - (y point) = slope (x - (x point)) you know it is the right equation because it gives you the slope, which is the same, and the point, which is given.

The way to get it into slope intersept form you just solve for y
