Answer:
I(x)=x+1
Step-by-step explanation:
Answer:
standard form is : - x^4 + 3 * x^2
This is an even function 4rth degree polynomial
Step-by-step explanation:
f(x) = x^2-x^4 +2x^2
simplify it by combining like terms.
f(x) = x^2 +2x^2 - x^4
f(x) = 3 * x^2 - x^4
standard form is : - x^4 + 3 * x^2
This is an even function 4rth degree polynomial
Answer:
Step-by-step explanation:
y = x + 95
y = 42 + 95
y=137 mm Hg
Answer:
The length of the yard is 60 feet while the width is 30 feet.
Step-by-step explanation:
If the length of Mr. Timmon's backyard is double the width, then the dimensions are related by the following expression:
length = 2*width
We also know the perimetter, since he has the exact length of fence to surround his whole yard, which is 180 feet. The perimeter of a rectangle is given by:
perimeter = 2*length + 2*width
Therefore,
180 = 2*length + 2*width
With the length being double the width, we have:
180 = 2*(2*width) + 2*width
180 = 4*width + 2*width
6*width = 180
width = 180/6 = 30
length = 2*width = 2*30 = 60
The length of the yard is 60 feet while the width is 30 feet.
