Answer:

Technical units conversion tool for speed and velocity measures. Exchange reading in feet per minute unit ft/min into miles per hour unit mph as in an equivalent measurement result (two different units but the same identical physical total value, which is also equal to their proportional parts when divided or multiplied).

One foot per minute converted into mile per hour equals = 0.011 mph

1 ft/min = 0.011 mph

Which exponential function is represented by the graph?

Anna [14]

Answer:

Step-by-step explanation:

Let's solve this using our formula for exponential functions:

$y=a(b)^x$ where a is the initial value and b is the growth/decay rate. We will fill that equation in with 2 of the coordinates on the graph and come up with the values for both a and b. (0, 3) and (1, 6):

$3=a(b)^0$ . Anything raised to the power of 0 is 1, so that means that

a = 3. We will use that value along with the x and y from the second coordinate to solve for b:

$6=3(b)^1$ . b to the first is just b, so our equation is

6 = 3b and

b = 2.

Our equation then is

$y=3(2)^x$ , the third choice down.

Identify all factors of the expression 12x^2-14x-6

Evgen [1.6K]

Let's solve this by using the quadratic formula:

$\frac{-b+-\sqrt{b^2-4ac} }{2a}$

Note that we only use the coefficients so a=12, b=-14, and c=-6.

Plug values in the quadratic equation:

$\frac{ - ( - 14)± \sqrt{ {( - 14)}^{2} - 4(12)( - 6) } }{2(12)}$

And so by evaluating those values we obtain:

$\frac{14+-\sqrt{484} }{24}=\frac{14+-22}{24} \\\\$

Now we have two answers which are our factors one where we add another where we subtract and so:

First factor:

$\frac{14+22}{24}=\frac{36}{24}=\frac{3}{2}$

Second Factor:

$\frac{14-22}{24}=\frac{-8}{24}=-\frac{1}{3}$

And so your factors are

$\frac{3}{2},-\frac{1}{3}$

meaning that those are your roots/x-intercepts.

On a blueprint lets say that every 1/4 inch is equal to 1 foot in real life.

Murrr4er [49]

Answer:

15 ft

Step-by-step explanation:

If every 1/4 of an inch is a foot, than every inch is 4 feet.

1 inch = 4ft

3 inches = 12ft

1/4 + 1/4 + 1/4 = 3/4

3/4=3 ft

12+3=15ft
