Answer:
BA = 25.5961
Step-by-step explanation:
To solve for side BA, we need to use the correct trigonometric function that relates (from the perspective of angle B) side AC and BA.
AC is Opposite of angle B
BA is the Hypotenuse
The function we use here is Sine. Sine is:
Sin(θ) = Opposite/Hypotenuse
So we simply substitute our information to solve.
Sin(62) = 22.6/BA
BA = 22.6/Sin(62)
Typing this into our calculator we get:
BA = 25.5961
(This is rounded to 4 decimal places)
Answer: $25
Step-by-step explanation: 25 times 3(because there are three people) =75 - 45(the amount they spent)=30 the amount they are left with all together.
it took me awhile to answer so sorry for the wait but i hope this helps.
This is system of Equations.
<span>2x + 3y =10
x + y = 3
</span>
x + y = 3 (multiply this by three) to get 3x + 3y = 9
2x + 3y =10
3x + 3y = 9 Subtract them
-1x = 1
x=-1
Now plug x back into the top equation and solve for y.
I hope this helps! If not, let me know! Have a fantastical day!
Please use "i" for the imaginary operator, not "I."
A third degree poly would have 3 factors and 3 zeros; you've supplied only 2 zeros.
Let's model the polynomial as y = ax^3 + bx^2 + cx + d.
We are told that the leading coefficient is -5. Therefore, our model becomes
y = -5x^3 + bx^2 + cx + d
The two given roots are 4-i and 4+i; if either is subst. into the above equation, y takes on the value 0 (this is the meaning of "root")
Thus, if x = 4-i, 0 = -5(4-i)^3 + b(4-i)^2 + c(4-i) + d.
If x = 4+i, 0 = -5(4+i)^3 + b(4+i)^2 + c(4+i) + d
Here we have two equations in three unknowns (b, c and d). There's not enough info to enable us to determine all three b, c and d.
One thing you might do at this point would be to set d=0 arbitrarily, and then solve the resulting two equations (without d) for b and c.
Can you take the ball and run with it from this point on?
