Suppose a deep sea driver dives from the surface to 248 feet below the surface. He then dives down 10 more feet. Use integers yo
Akimi4 [234]

Answer:

Initial dive: - 248 (below the surface which represents '0')

Second dive: -10

Present depth -248 + -10 = -258 feet below the surface

Step-by-step explanation:

We can use negative integers to represent real-world scenarios such as in elevation and descent, bank account balances and temperatures.  In this case, because a diver is descending below the surface of the water, the surface of the water represents the '0' and going down into the water would be negative integers.  So, his initial dive is 248 down, or negative 248 (-248), he then dives down an additional 10 feet, or negative 10 (-10).  Since the second dive is in addition to his initial dive, we add the two integers together:

-248 + -10 = -258 feet

Five the equation of line that is perpendicular to f(x)=-2x+1 that goes through point (0,5)
Alinara [238K]

Answer:

y = \frac{1}{2} x + 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

f(x) = - 2x + 1 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-2} = \frac{1}{2} , then

y = \frac{1}{2} x + c

the line crosses the y- axis at (0, 5 ) ⇒ c = 5

y = \frac{1}{2} x + 5 ← equation of perpendicular line
