Answer:
4/15 is the answer my guy
Step-by-step explanation:
5/3 x 4/25= 20/75 simplified is 4/15
Answer: f(x) = (x + 3)(x – 7)
Step-by-step explanation: Use "standard form" of the function and insert values given: vertex (2,-25) intercept point (7,0)
f(x) = a(x-h)² + k from vertex, h is 2 y is -25 from intercept, x is 7 f(x) is 0
to find a, 0 = a(7-2)² +(-25) 0 = a(7-2)² -25 add 25 to both sides
25 = a(5)² 25 = 25a 25/25 = a 1=a (seems useless but verifies implied "a"coefficient is 1)
f(x) = a(x-h)² + k solve to get the quadratic form
f(x) = (x-2)² -25 (x - 2)² is x² -4x +4
f(x) = x² -4x +4 -25 simplify
f(x) = x² -4x - 21 then factor
f(x) = (x + 3)(x - 7)
Answer:
32.4
Step-by-step explanation:
1% of 45 is .45
if you multiply .45 x 28 (because you want 28%)
you get 32.4
Hello :
<span>sin 2x = sin x and 0 ≤ x ≤ 2π. .....51°
note : sina = sinb equivaut : (a = b +2k</span>π) or ( a = π - b +2kπ) .... k∈ Z
(1) equiv : ( 2x = x +2kπ) or (2x = π - x +2kπ)
( x = 2kπ) or ( x = π/3 + 2kπ/3)....(general solution )
but : 0 ≤ x ≤ 2π
k = 0 : x = 0 , x = π/3
k= 1 : x = 2π , x = π
k = 2 ; x = 5π/3
