Step-by-step explanation:
x⁴+3x³-4x²=0
x²(x²+3x-4)=0
x²+3x-4=0
x²+4x-x-4=0
x(x+4)-1(x+4)=0
(x+4)(x-1)=0
x=-4 or 1
x can't be negative
therefore x=1
x+4=1+4=5
Answer
given,
Chef has a = 238 pound salmon
slice of filet for one serving = 4 ounce
a) 1 pound = 16 ounce
for one serving
for each serving in pounds =
b) number of fillet that chef can create of 4 ounce
1 pound = 8 serving
238 pound = 8 × 238
238 pound = 1904 serving.
c) there is no left over of salmon.
Answer:
a. For →
b. For →
c. For →
d. For →
Step-by-step explanation:
Since the variables "x" and "y" are inversely related, the equation has the following form:
Where "k" is the constant of variation.
In this case we know that:
So, the equation is:
Therefore, substituting the given values of "x" into the equation, we get:
a. For →
b. For →
c. For →
d. For →
Answer:
x ≈ 8.39
Step-by-step explanation:
You'd have to use the tangent ratio in order to solve for x.
tangent ratio = opposite/adjacent
tan 50° = 10/x
x = 10/tan 50°
x = 8.39099631177
≈ 8.39
