We are asked in this problem to find the real root of the polynomial f(x) = x3 + 0.5x2 + 4.5. in this case, to find the root of the equation, we equate the equation to zero.
<span>f(x) = x³ + 0.5x² + 4.5 = 0
2x3 + x^2 + 9 = 0
</span><span>x1=−1.83557
</span>x2=0.66779+1.41619∗i
x3=0.66779−1.41619∗i
answer is -1.84
Using the 2 points (-7,0) and (0,4):-
slope = (4 - 0) / (0 - -7) = 4/7 (answer)
Answer:
3,989.2
Step-by-step explanation:
The word tenth goes after the decimal so the number is 2 and sense the number 3 is after and will be rounded down the answer is 3,989.2
The complete question in the attached figure
we know that
[scale]=1 in / 30 ft
scale=[measure in the drawing]/[measure in the actual]
[measure in the actual]=[measure in the drawing]/[scale]
so
[measure in the drawing]=1.25 in
scale=1/30
then
[measure in the actual]=[1.25]/[1/30]------> 1.25*30-----> 37.5 ft
the answer is<span>
the Actual height is 37.5 ft</span>
