Answer:
62 or A
Step-by-step explanation:
180-90-28=62
We can solve for the length of side a to the nearest whole number using the Laws of Cosines such as the formula is shown below:
a²=b²+c²-2bcCosA
Solving for the value of a, we have:
a²=10²+14²-2(10)(14)cos54°
a²=131.42
a=11.46
The answer is 11.46 or 11.5.
Answer:
46 and 59
Step-by-step explanation:
let the smaller number be n then the larger number is n + 13 and summing them gives the equation
n + n + 13 = 105
2n + 13 = 105 ( subtract 13 from both sides of the equation )
2n = 92 ( divide both sides by 2 )
n = 46
the 2 numbers are n = 46 and n + 13 = 46 + 13 = 59
Answer: B
Step-by-step explanation:
Answer:
t is between 0 seconds and 4.878
Step-by-step explanation:
Given:
Inequality:
Required
Determine the value(s) of t
To answer this question, we simply solve the inequality
Subtract 10 from both sides
Multiply through by -1
Solve the value of t using quadratic formula
Where
<em>a = 4.9; b = -22 and c = -9.25</em>
So:
Split the expression
or
or
or
Since t cannot be negative; Then
<em>Hence; t is between 0 seconds and 4.878</em>
