Answer:
b = 6 mm
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 8² = 10²
b² + 64 = 100 ( subtract 64 from both sides )
b² = 36 ( take the square root of both sides )
b = 
= 6

<h2>
B. <u>g(x) = 4x²</u></h2>
Step-by-step explanation:
f(x)= x²
the shape of f (x ) and g( x ) is same.
and those graphs lower point is ( 0 , 0 )
therefore,
will, g(x) = kx² (k ∈ real numbers)
the g(x) graph goin through the point ( 1 , 4 )
therefore,
4 = k × 1²
k = 4
∴ <u>g(x) = 4x²</u>

Answer:
1.4
Step-by-step explanation:
We want to find the multiplier n such that ...
arc length = n × radius
n = arc length / radius = (9.8 cm)/(7 cm)
n = 1.4
The subtended arc is 1.4 times as long as the circle's radius.
