Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point A(1, 4)

Point B(-2, -3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [DF]: $\displaystyle d = \sqrt{(-2-1)^2+(-3-4)^2}$
(Parenthesis) Subtract: $\displaystyle d = \sqrt{(-3)^2+(-7)^2}$
[√Radical] Exponents: $\displaystyle d = \sqrt{9+49}$
[√Radical] Add: $\displaystyle d = \sqrt{58}$
[√Radical] Evaluate: $d = 7.61577$
Round: $\displaystyle d \approx 7.62$

The ratio of the length 2.0 meters to the length 1.2 meters is

photoshop1234 [79]

Answer:

The Ration of length 2.0 meters to the length 1.2 meters = 5 : 3

Step-by-step explanation:

The given two length are 2.0 m and 1.2 m

Length L1 = 2.0 m And

Length L2 = 1.2 m

SO, The ratio of L1 : L2 = $\frac{2.0}{1.2}$

Or, The ratio of L1 : L2 = $\frac{20}{12}$

∴ The ratio of L1 : L2 = $\frac{5}{3}$

Hence The ratio of L1 : L2 is 5 : 3 Answer

A) The cosine rule can be used to find the value of x in the triangle below.

BartSMP [9]

Answer:

see explanation

Step-by-step explanation:

(a)

(the side required )² = sum of squares of other 2 sides - ( 2 × product of other 2 sides and cos(angle opposite side required ) )

x² = 12² + 15² - (2 × 12 × 15 × cos71°)

(b)

x² = 144 + 225 - 360cos71°

= 369 - 360cos71° ( take square root of both sides )

x = $\sqrt{369-360cos71}$

≈ 16 cm ( to the nearest integer )

Using the diagram, what is the value of x? A. 110° B. 30° C. 60° D. 120°

Sidana [21]

The value of x would be

D. 120 degrees

That is because a line is 180 degrees, subtract 60 degrees since angle is going to be 60 degrees (equilateral triangle) like this:

180 - 60 = 120 degrees
