Answer:
B. 80
Step-by-step explanation:
3 consecutive integers: x-1 , x , x+1
(x-1) + x + (x+1) = -27
3x = -27
x = -9
smallest: -9-1 : -10
largest: -9+1 : -8
product of the smallest and largest of the three integers: (-10)*(-8)=80
For proportions just cross multiply.
8(y+2)=44
8y+16=44
8y=28
y=28/8
4x^2+12x+7x
4x^2+19x
Was it meant to equal something or are you just simplifying the equation?
Answer and explanation:
Given : The position of an object moving along an x axis is given by
where x is in meters and t in seconds.
To find : The position of the object at the following values of t :
a) At t= 1 s




b) At t= 2 s




c) At t= 3 s




d) At t= 4 s




(e) What is the object's displacement between t = 0 and t = 4 s?
At t=0, x(0)=0
At t=4, x(4)=14.24
The displacement is given by,



(f) What is its average velocity from t = 2 s to t = 4 s?
At t=2, x(2)=-1.76
At t=4, x(4)=14.24
The average velocity is given by,




Answer:
Sum angle of triangle BHD = 180°
36 + 39 + BHD = 180
BHD = 180 - 36 - 39
= 105°
BHD + x° = 180° (straight angle)
105° + x° = 180°
x = 180 - 105
= 75°
