Consider the parabola given by the equation: f(x) = 2x2 + 14.0 – 4

Softa [21]

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

The length of the tunnel is 460miles. If 1 inch represents 60 miles what is the length of the tunnel?

kotegsom [21]

Answer:

The length of the tunnel is 7.66667 inch

Step-by-step explanation:

We are given

1 inch =60 miles

now, we can find for 1 mile

so,

60 miles = 1 inch

we get

$1mile=\frac{1}{60}inch$

we are given

total length is 460 miles

so, we can multiply both sides by 460

$460\times 1mile=460\times\frac{1}{60}inch$

now, we can simplify it

$460miles=7.66667inch$

So,

The length of the tunnel is 7.66667 inch
