W varies jointly as x and p . If w=78 when x=2 and p=10, find x when w=858 and p=5.5
Lemur [1.5K]
W=kxp
where
k is the constant of proportionality given by:
k=w/xp
<span> If w=78 when x=2 and p=10 then
</span>k=78/(2*10)
k=3.9
thus the formula is:
w=3.9xp


b] <span>find x when w=858 and p=5.5
plugging the values in the formula we get:
858=3.9</span>×5.5×x
hence 
x=858/(3.9×5.5)
x=358/21.45
x=16.69

Find the area of the kite. ) 210m ^ 2 ) 140m ^ 2; 420m ^ 2; 224m ^ 2
Nikolay [14]

Answer:

from the image above

Triangle ABE = Triangle ADE

AE = AE ( common).

angle AEB = angle AEO ( each 90°)

AB = AD ( given).

by side angle side criteria

so area of ABE = area of ADE

similarly,

BC = DC ( given)

BEC = DEC ( 90°)

EC = EC ( 9m each)

so area of BEC = Area of DEC
