If you would like to find a pair of equations that best models the relationship between p and d, you can do this using the following steps:
p is 2 more than d ... p = d + 2
p is 1 less than d ... p = d - 1
The correct result would be p = d + 2 and <span>p = d - 1.</span>
The common difference equals:
10 (as 14-4=10, 24-14=10…)
The explicit formula of this sequence is:
Because Tn=4+(n-1)•10
T1=4+(1-1)•10=4
T2=4+(2-1)•10=14
.
.
.
Therefore T8=4+(8-1)•10=74
So the answer is the second option:)
This is a question of resolving the forces in question into horizontal and vertical and then finding the action of the resultant force.
The first force acts at an angle less than 90° and thus its resolved forces are positive. The second force acts at angle larger than 90° and is incident and thus its horizontal value is positive while its vertical value is negative.
Therefore;
For force of 300 N at 30°;
Horizontal value = 300*Cos 30 = 259.81 N
Vertical value = 300*Sin 30 = 150 N
For 150 N at 135°;
Horizontal value = 150*Cos (180-135) = 106.07 N
Vertical value = -150*Sin (180-135) = -106.07 N
Then,
Resultant horizontal value = 259.81+106.07 = 365.88 N
Resultant vertical value = 150-106.07 = 43.93 N
Therefore,
Resultant force, v = Sqrt (365.88^2+43.93^2) = 368.51 N
Angle of action measured from horizontal = tan ^-1(43.93/365.88) 6.85°
Then,
v = 368.51 N at 6.85° from horizontal
Answer:
V=84
Step-by-step explanation:
1. 7*6=42. make 42 a fraction by making it 42/1.
2. 1/3*42/1=42/3
3. make 6 a fraction by making it 6/1
4. 42/3*6/1=252/3
5. 252/3=84
