we know that
Linear function:
A linear function is a function whose graph is a straight line, that is a polynomial function of degree at most one
For exp: 
Here , we are given
we can see that
x is in denominator
so, this can not be linear function........Answer
Answer:
Step-by-step explanation:
f(x) = 2x² + 14x - 4
= 2(x² + 7x) - 4
= 2(x² +7x + 3.5²) - 2(3.5²) - 4
= 2(x+3.5)² - 28.5
vertex (3.5, -28.5) = (7/2, -57/2)
The vertical intercept is the y-intercept, i.e., f(0) = -4.
The x-intercepts are the values of x for which y=0.
2x² + 14x - 4 = 0
x = [-14±√(14²-4(2)(-4))]/[2(2)] = [-7±√57]/2 ≅ -7.27, 0.27
Answer:
Concept: Numerical Analysis
- We want a number X such that X × 0.80 = 560,000
- So we divide 560000 by 0.80 to get X
- X = 700,000

The surface area is 33ft square.
Answer:
h = 24 cm
Step-by-step explanation:
volume of water in the cylinder = volume of water in the rectangular base container
But ,
volume of cylinder = 
h
where: is the radius and h is the height.
volume of cuboid = length x width x height
= l x w x h
So that;
h = l x w x h
But, r = 
= 
= 9 cm, height of cylinder = 28 cm, length = 27 cm, width = 11 cm, = 
.
Thus,
x 
x 28 = 27 x 11 x h
x 81 x 28 = 27 x 11 x h
7128 = 297h
h = 
= 24
h = 24 cm
The depth of the water in the container is 24 cm.
