When two secant lines intersect each other outside a circle, the products of their segments are equal.
14(с + 14) = 10(10 + 20)
14с + 196 = 10 * 30
14с +196 = 300
14с = 300 - 196
14с = 104
с = 104/14
с ≈ 7.4
Answer:
Step-by-step explanation:
In this geometry, the triangles are similar. That means corresponding sides are proportional:
short side/long side = x/10 = 10/25
x = 100/25 = 4 . . . . multiply by 10
__
hypotenuse/short side = y/x = (x+25)/y
y² = 4(29) = 116 . . . . . use 4 for x; cross multiply
y = √116 ≈ 10.8
Answer:
-x + y = 8
Step-by-step explanation:
Slope =
=
slope = 1, m represents the slope
y - y1 = m(x - x1)
choose any point ( -1, 7 ) or ( 2,10 )
y - 7 = 1( x + 1 )
y - 7 = x + 1
-x + y = 8
In case of Nina:
slope of graph = speed = 48-32/6-4 = 16/2 =8
y-32 =8(x-4)
y-32=8x-32
y=8x
d=8t
at x= 0 i.e at t= 0
d= 0m
In case of Ryan:
slope =speed = 47.5-35=6-4 = 12.5/2 =6.25
y-35=6.25(x-4)
y-35=6.25x-25
y=6.25x+10
d=6.25t+10
at t = 0, d= 10m
RYAN had a head start of 10 m
Answer:
He can bring 6 people to the zoo.
Step-by-step explanation:
7 + 15.50x = 109
subtract 7 from both sides
15.50x = 102
divide by 15.50 on both sides
x = 6.58064516129 = 6 people
