Answer:

1 dm on map equals 25 km in real distance.

Step-by-step explanation:

We have been given that 50 km in real distance is 2 dm on a map. We are asked to find the scale of the map.

To answer our given problem we will use unit rate. When rates are expressed as a quantity of 1, they are called unit rates. Such as 3 feet per second or 10 miles per hour.

To find the unit rate we will divide 50 km by 2 dm.

$\text{Unit rate}=\frac{50\text{ km}}{2\text{ dm}}$

$\text{Unit rate}=25\frac{\text{ km}}{\text{ dm}}$

Therefore, 1 dm on map equals 25 km in real distance or we can say scale of map is 25 km per dm.

A car entering the freeway accelerates from 10.2 m/s with a constant acceleration of 4.4 m/s 2 . What is the car's final velocit

Ilya [14]

Givens

a = 4.4 m/s^2 This is an acceleration and is positive.

vi = 10.2 m/s

t = 4.2 seconds

vf = ????? The cruising speed in this case is vf.

Formula

a = (vf - vi)/t Notice the 3 givens and what you seek determine the formula

Solve

4.4 m/s^2 = (vf - 10.2)/4.2 Multiply both sides by 4.2

4.4 * 4.2 = vf - 10.2

18.48 = vf - 10.2 Add 10.2 to both sides

18.48 + 10.2 = vf 8.28 is the second best answer.

28.68 = vf This is your cruising speed.

What is a polynomial ?

ikadub [295]

aApolynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

There are 3 sets of polynomials; LINEAR, QUADRATIC and CUBIC

Linear: $ax + b = 0$
