What us the equation of the line that passes through point (2,5) and (0, -2)

Mathematics
1 answer:
erastovalidia [21]3 years ago
5 0

Answer:

y = 7/2 x -2

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

   = (-2 -5)/(0-2)

   =-7/-2

   = 7/2

We know the y intercept is -2  ( The x coordinate is 0)

Using the slope intercept form of the equation

y = mx+b  where m is the slope and b is the y intercept

y = 7/2 x -2

A weed called the raindrop vine is known for growing at a very fast rate. It can grow up to 0.75 feet per day. How fast in inche
viktelen [127]

R = rate of growth of raindrop vine = 0.75 feet/day

we know that :  1 feet = 12 inches

1 day = 24 hours

replacing the units accordingly in the above expression for rate of growth of raindrop vine

R = 0.75 (feet/day)  (12 inches/1 feet) (1 day/24 hours)

R = (0.75 x 12 /24) (inches/hour)

R = 0.375 inches/hour

Assume that a driver faces the following loss distribution:Outcome Probability12,000 0.15 0 0.851. What is the expected loss?2.
xxMikexx [17]

Answer:

- 1800 ; 4284.8579 ;

Step-by-step explanation:

Given the table :

Outcome _____ probability

-12000 ________ 0.15

__ 0 __________ 0.85

Expected loss, m: Σx*p(x)

(-12000 * 0.15) + (0 * 0.85)

-1800 + 0 = - 1800

Standard deviation = sqrt(Var(x))

Var(x) = Σx²*p(x) - m²

(-12000^2 * 0.15) + (0^2 * 0.85)] - 1800^2

21,600,000 - 3240000

= 18360000

Standard deviation = sqrt(18360000)

Standard deviation = 4284.8579

I don't get this pls help
dmitriy555 [2]

Answer:

  d, e

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  a^-b = 1/a^b

__

In this case, it means the product is ...

  (6^1)(6^0)(6^-3) = 6^(1+0-3) = 6^-2 = 1/6^2 = 1/36

__

The 6 without an exponent is equivalent to 6^1, an exponent of 1.

The sum of the exponents is -2.

Add the exponents to simplify the expression.

The value of the expression is 1/36.

An equivalent is any expression that results in 6^-2. One such is (6^5)(6^-7).

__

Only the last two choices, d and e, apply.
