Answer:
(x, x2 -2x+8) where −5 ≤ x ≤ 3
Step-by-step explanation:
The given function is f(x)=x2- 2x+ 8
We want to select the option that describes all the solutions to the parabola.
The domain of the parabola is −5 ≤ x ≤ 3.
This means that any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.
This can be rewritten as (a,-a2- 2a+ 8)
Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:
(x, x2 -2x+8) where −5 ≤ x ≤ 3.
Answer:
<em><u>Using the mid-term break formula for all of them.</u></em>
a) x²+7x+12
= x²+3x+4x+12
= x(x+3)+4(x+3)
= (x+4)(x+3)
b) x²+6x+8
= x²+2x+4x+8
= x(x+2)+4(x+2)
= (x+4)(x+2)
c) x²+5x+6
= x²+2x+3x+6
= x(x+2)+3(x+2)
= (x=3)(x+2)
d) x²+8x+7
= x²+7x+x+7
= x(x+7)+1(x+7)
= (x+1)(x+7)
Answer:
$10.75 per scarf
Step-by-step explanation:
Take the price and divide by the number of scarves.
$96.75 / 9 scarves
$10.75 per scarf
the angle is in degrees, thus, when taking either sine or cosine, make sure your calculator is in Degree mode
