A helicopter flies at a rate of 150 miles per hour. How many miles per second is this

Mathematics
1 answer:
den301095 [7]3 years ago
8 0

Answer:

So,converting 150 mile per hour into miles per second we get 0.0416 miles per second

Step-by-step explanation:

Given:

Helicopter files at: 150 miles per hour

Required:

We need to convert 150 miles per hour to miles per second

Solution:

We know that, 1 \ mile\ per\ hour = \frac{1}{3600} \ miles\ per\ second

So, 150 mile per hour will be: (We will be dividing 150 by 3600 to get miles per second)

1 \ mile\ per\ hour = \frac{1}{3600} \ miles\ per\ second\\150 \ mile\ per\ hour = \frac{150}{3600} \ miles\ per\ second\\150 \ mile\ per\ hour = 0.0416 \ miles\ per\ second

So,converting 150 mile per hour into miles per second we get 0.0416 miles per second

What is the solution to the system of equations
ExtremeBDS [4]

Answer:

Y = 2

X = 3

Step-by-step explanation:

Substitution:

6(4y-5) - y = 16

24y-30-y=16

23y=46

Y = 2

So then:

6x-2 = 16

6x = 18

X = 3

Find the area of the shaded region for the given figure in terms of x.
Vlada [557]

Answer:

Area of the shaded region = (6x + 3)

Step-by-step explanation:

Area of the shaded region = Area of the large rectangle - Area of the small rectangle

Area of the large rectangle = Length × Width

                                             = (x + 2)(x + 2)

                                             = (x + 2)²

                                             = x² + 4x + 4

Area of the small rectangle = (x - 1)(x - 1)

                                             = (x - 1)²

                                             = x² - 2x + 1

Area of the shaded region  = (x² + 4x + 4) - (x² - 2x + 1)

                                             = 6x + 3

Area of the shaded region = (6x + 3)

The table of ordered pairs (x, y) gives an exponential function.
Basile [38]

Answer:

f(x) = 12*(2)^x

Step-by-step explanation:

A generic exponential equation is written as:

f(x) = A*(r)^x

And we also know that this equation passes through:

(-1, 6)

(0, 12)

(1, 24)

(2, 48)

For the second point, (0, 12) we know that when f(0) = 12

Then:

f(0) = 12 = A*(r)^0

And for every real number different than zero, a^0 = 1

Then:

f(0)  = A*1 = A = 12

Then the equation is:

f(x) = 12*(r)^x

Now we can use one of the other points, like (1, 24)

Then f(1) = 24

We can solve:

f(1) = 24 = 12*(r)^1  = 12*r

24/12 = r

2 = r

Then the equation is f(x) = 12*(2)^x

Now we need to check if this function also passes through the points (-1, 6) and (2, 24):

f(-1) = 12*(2)^-1 = 12/2 = 6

f(2) = 12*(2)^2 = 12*4 = 48

Nice.

So we can see that the function is f(x) = 12*(2)^x
