Find the distance behween the points given
(2, 2) and (5,5)

Step-by-step explanation:

=

Answer & Step-by-step explanation:

First, we must know the formula for finding the distance between two given points.

We will plug in (2,2) for (x1,y1) and we will plug in (5,5) for (y2,y1).

Subtract 2 from 5 in both parentheses.

Simplify the exponents.

Add 9 and 9 together.

Simplify the radical.

This number can also be simplified into 4.24.

So, the distance between the two points is 3√2 units or 4.24 units.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
