Answer:
24.8
Step-by-step explanation:
This is pythagorean theorem since it is a right-angled triangle.
A^2 + B^2 = C^2
Where A and B is the 2 sides that make the right angle
And C is the hypotenuse (the longest side)
So we just substitute in
19^2 + 16^2 = C^2
361 + 256 = C^2
617 = C^2
sqrt(617) = C
24.839 = C
Rounded up to the nearest tenth = 24.8
O A O
S H C H T A
Looking for s (sin)
O
So you use the triangle of S H
O = opposite
H = hypotenuse
So you’d then do the O/H
So the opposite being 12cm and the hypotenuse being 13cm
The answer would then be 13/12
Hope this helps! :)
Answer:
D
Step-by-step explanation:
Given a polynomial f(x) with roots say x = a and x = b, then the factors are
(x - a) and (x - b) and f(x) is the product of the roots, that is
f(x) = (x - a)(x - b)
Here the roots are x = - 4, x = 0 and double root at x = 7
Thus factors are (x - (- 4)), (x - 0), that is (x + 4) and x
Given a double root at x = 7 the factor is (x - 7)², thus polynomial is
y = x(x + 4)(x - 7)² → D
