Answer:

horizontal = 5.7

vertical = 8.2

Step-by-step explanation:

Sin(55) = \frac{cb}{ac} \\ = 0.82 -> cb = 0.82*10= 8.2

Cos(55) = \frac{ab}{ac}= 0.57 -> ab = 0.57*10 = 5.7

Given the following rectangle and circle, at what approximate value of x are the two areas equal? x ≈ 5.8 x ≈ 3.4 The curves do
SIZIF [17.4K]

The approximate value of x will be approximately equal to 3.4

<h3>Area of triangle and circle</h3>

The formula for calculating area of rectangle is expressed as:

A  = lw

  • l is the length
  • w is the width

Ar = (3x-1)(x+2)

Ar = 3x^2+6x-x-2

Ar = 3x^2 + 5x - 2

For the circle

Ac = πr²

Ac = 3.14(x-3)²

Ac = 3.14(x²-6x+9)

Ac = 3.14x² - 18.84x + 28.26

If the area are equal;

3x² + 5x - 2 = 3.14x² - 18.84x + 28.26

3.14x² - 3x² - 5x - 18.84x + 30.26 = 0
0.14x²-23.84x+30.26 = 0

On factorizing the equation, the approximate value of x will be approximately equal to 3.4

What is the range of the function represented by the graph?<br> I need help ASAP
kumpel [21]

Step-by-step explanation:

The range of a function is basically the y-value of the lowest point in the function and the y-value of the highest point in the function.

In the graph shown, the lowest point is (0,1) and the highest is (3, 4). Their y-values are 1 and 4 respectively.

The points are not connected in a straight line. Instead, they are separate points with a difference of 1 in their y-values.

So the answer is {1, 2, 3, 4}
