Answer:
6) x = 17 ft
7) 42 in
Step-by-step explanation:
6) length of the tangents are equal.
2x - 7 = 27
2x = 34
x = 17
7) if you draw a line from T passing through the centre of the circle, it will divide the triangle into two congruent triangles
Perimeter = 2(5+7+9) = 42 in
Answer:
y = 2(x + 3)^2 - 17.
Step-by-step explanation:
y=2x^2+12x+1
y = 2(x^2 + 6x) + 1
y = 2[( x + 3)^2 - 9] + 1
y = 2(x + 3)^2 - 18 + 1
y = 2(x + 3)^2 - 17.
Answer:
$1.80
Step-by-step explanation:
11.10-5.70=5.40
5.40/3=1.80
Answer:
see below
Step-by-step explanation:
The arc length (s) can be found in terms of angle (θ) and radius (r) as ...
s = rθ
Dividing by r gives ...
s/r = θ
Since the angles are the same for the two circles, the ratios of interest are ...
