Answer:
<h2>X=-6</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>let's solve:</h3>
- add 12 to both sides:-5x-12+12=18+12=>-5x=30
- divide both sides by-5:-5x/-5=30/-5
- therefore x=-6
Answer: t = 7.85seconds
Step-by-step explanation:
Given that :
Height of tower = 986 Feets
Function s(t) = 16t^2
To find the time t 8 in Seconds taken for an object to fall to the ground from the top of the building
16t^2 = 986
t^2 = 986/16
t ^2 = 61.625
Take the square root of both sides
t = sqrt(61.625)
t = 7.85seconds
C=2 pie r
(example circumference=28)
28=2 x 22\7 x r
28=6.29r
then divide both sides by 6.29
28\6.29=4.45
r=4.45
Answer:
Yes
Step-by-step explanation:
There is a linear relationship, so there is a constant change in the graph and thus a proportional relationship.
