Mathematics
1 answer:
Crank3 years ago
3 0

Answer:

<u>Step 1:  Find the x</u>

2x + 5:  Solve

2x + 5 - 5 = 0 - 5

2x / 2 = -5 / 2

x = -5/2

3x + 15:  Solve

3x + 15 - 15 = 0 - 15

3x / 3 = -15 / 3

x = -5

Find the distance that the points is given on the graph ?
EleoNora [17]

From the graph, the given points are (2,-1) and (4,0). Use the distance between two points formula:

\large \boxed{ \sqrt{ {(x_2 - x_1)}^{2} +  {(y_2 - y_1)}^{2} } }

Substitute these points in the formula.

\large{ \sqrt{ {(2 - 4)}^{2}  +  {( - 1 - 0)}^{2} } } \\  \large{ \sqrt{ {( - 2)}^{2} +  {( - 1)}^{2}  } }  \\  \large{ \sqrt{4 + 1} \longrightarrow  \sqrt{5}  }

Hence, the distance is √5

Answer

  • √5

What is the approximate diagonal distance from one corner of a 3 inch by 5 inch index card to the opposite corner
77julia77 [94]

Answer:

5.83 inches

Step-by-step explanation:

The card is a rectangular shaped object, drawing a diagonal from one corner to the other, divides the rectangle into two right angled triangles with the diagonals as the hypothenuse.

Using Pythagoras theorem.

c^2 = a^2 + b^2

Given;

Side a = 3

Side b = 5

Substituting the given values;

c^2 = 3^2 + 5^2

c = √(9+25)

c = √34

c = 5.83 inches

Choose the function whose graph is given by:
wolverine [178]

<em>Greetings from Brasil...</em>

In a trigonometric function

F(X) = ±UD ± A.COS(Px + LR)

UD - move the graph to Up or Down (+ = up | - = down)

A - amplitude

P - period (period = 2π/P)

LR - move the graph to Left or Right (+ = left | - = right)

So:

A) F(X) = COS(X + 1)

standard cosine graph with 1 unit shift to the left

B) F(X) = COS(X) - 1 = -1 + COS(X)

standard cosine graph with 1 unit down

C) F(X) = COS(X - 1)

standard cosine graph with shift 1 unit to the right

D) F(X) = SEN(X - 1)

standard Sine graph with shift 1 unit to the right

Observing the graph we notice the sine function shifted 1 unit to the right, then

<h3>Option D</h3>

<em>(cosine star the curve in X and Y = zero. sine start the curve in Y = 1)</em>
