Answer:
(-6, -5).
Step-by-step explanation:
If there is a zero between the integers there will be a change of sign of f(x).
x^3 + 5x^2 - x - 6
f(1) = 1 + 5 - 1 - 6 = -1
f(-1) = -1 + 5 + 1 - 6 = -1
f(2) = 8 + 20 - 2 -6 = 20
There' a change of sign between f(1) and f(2) so there is a zero between (1, 2).
f(-2) = -8 + 20 + 2 - 6= 6
So there is also a zero between -1 and -2. (-2, -1)
F(-4) = 14, f(-5) = -1 = change of sign so there is also a zero in (-5,-4)
f(-6) = -36 - no change in sign between -5 and -6.
Answer:
D. 1/2 it either happens or not
So 15%=15/100=3/20 so
80=3/20 of a number
multiply both sides by 20/3 to clear fraction
1600/3=a number
533.33
te number is 533.3333333
Answer:
24 degrees, so D
Step-by-step explanation:
The total angle of a triangle is 180 degrees.
(quadrilateral is 360 degrees)
So, the question tells you two angles which are,
66 and 90 degrees
To find out the third angle, you have to add the two degrees, so
156, which means,
156 + x = 180
To solve the equation, it is,
24.
