Answer:
a) 1) equilateral (all equal sides)
2) isosceles (equal opp. sides)
3) scalene (unequal sides)
b) 1) obtuse (> 90°)
2) acute (< 90°)
3) right (90°)
c) 1) Equilateral & equiangular (< 90° & equal sides)
2) Right scalene (90° & diff sides)
3) Acute isosceles (< 90° & 2 equal opp. sides)
Hope it helps ⚜
Angle of elevation= 61°
Height of Sarah =h = 5.5ft
Distance(from base of statue) between Sarah and statue = 166 ft
Now,
tan(61°)= H/166
H= 299.47 ft
but in the height H you also add the height of of Sarah then you get the height of statue.
Height of <span>statue of the liberty = H+h
= 299.47+5.5
= 304.97 ft</span>
Answer:
D
Step-by-step explanation:
Given (x, y) is a point on f(x), then the corresponding point on the inverse g(x) is (y, x)
Hence
(8, 3) → (3, 8)
(4, 1) → (1, 4)
(0, - 1) → (- 1, 0)
(- 4, - 3) → (- 3, - 4)
That is the last set of points represents g(x)
Answer:
f(x) = x² - 9
Step-by-step explanation:
Given x = a is a zero of the polynomial f(x) then (x - a) is a factor
Given zeros are x = 3 and x = - 3, then corresponding factors are
(x - 3) and (x - (- 3) ), that is
(x - 3) and (x + 3)
The function is then the product of the factors, that is
f(x) = (x - 3)(x + 3) ← expand using FOIL
f(x) = x² - 9
