Answer:
15
Step-by-step explanation:
The amount of zeros of a function depends on the highest degree of such function.
Since the highest degree of the given polynomial is 15, hence the function will have 15 zeros
If you follow PEMDAS
P-parentheses
E-exponent
M-multiplication
D-divide
a-addition
s-subtraction
then you should look in the parentheses and multiplying 3x should be your first step IF you know x
hope this helps :)
These are difficult. You'll have 3 equations with 3 unknowns in the end to solve in order to get the coefficients right. The standard form for a circle with this type of info is
. We have 3 points with different x and y coordinates that we will sub in to get these 3 equations we seek. First point (29, 1):
. This simplifies down to 842+29D + E + F =0. That's the first of 3 equations. Next point (-19, 1):
which simplifies down to 362-19D+E+F=0. That's the second equation. Last point (-2, 18):
. Which simplifies down to 328-2D+18E+F=0. That's the 3rd equation. In all of these move the constants over to the other side of the equals sign. 29D+E+F= -842; -19D+E+F= -362; -2D+18E+F= -328. Take the first 2 equations and solve for D. Do this multiplying one of them by -1 to get a set of equations that are 29D+E+F= -842 and 19D-E-F= 362. Solve this by elimination and the E and the F cancel each other out leaving you with 48D= -480 and D = -10. Now take the second 2 equations and sub in the value for D you just found and work on eliminating either E or F. -19(-10) +E+F= -362 which simplifies to 190+E+F= -362; -2(-10)+18E+F= -328 simplifies to 20+18E+F= -328. Move the constants from the left to the right by subtraction to get a set of equations that is E+F= -552 and 18E+F= -348.Solve that first equation for E: E=-552-F and sub it into the second equatiion. 18(-552-F)+F= -348 and F= -564. Now let's go back to E+F= -552 and sub in our F of -564 to find that E = 12. Therefore, our equation, when all is said and done an hour later, is
. Not sure if that's the form your teacher wants it in, but that's standard. Ugh.
Given:
To Determine: The height of the silo
Solution
Let us compare the ratio of Steve's height and shadow with the height and shadow of the silo
The ratio would be
Determine the height of the silo by cross-multiplying
Hence, the silo is 90ft tall
