Answer:
(-3,-43) and (3,107)
Step-by-step explanation:
input 25x+32 for y
25x+32=5x²+25x-13
32=5x²-13
-5x²=-45
x²=9
x=+-3
which means you separate the solution
x= -3
x= 3
then input the answers you got for x, in both equations. Then you'll get your y.
y=25(-3)+32
-43
Then check your answer.
Then input the other answer you got for x.
I may be wrong, but I tried and checked my answers.
<u>Answer-</u>
<em>The cubic equation-</em>
<em></em>
<em>Milk consumption in 1994 was </em><em>58.4 pounds.</em>
<u>Solution-</u>
The general form of a cubic model is,
x = input variable = year - 2000 i.e number years after 2000
y = output variable = milk consumed in pounds
Then putting the values from the table,
--------------------------1
-------------2
-------------3
------------4
Solving equations (1), (2), (3) and (4) simultaneously we get,
So, the equation becomes,
In order to get the milk consumption in 1994, putting x=94
Therefore, milk consumption in 1994 was 58.4 pounds.

One number to the next is multiplied by -3, the first term is -4, second 12, third -36, fourth 108, keep going
Answer:
28.3
Step-by-step explanation:
tan = opposite/adjacent
tan (58) = 1,600335
opposite = tan * adjacent
opposite = 1,600335 * 15 = 24,005018
For the Pytagorean theorem
x = √24,005018^2 + 15^2 = 28,306199 = 28.3
