What is the domain of the following parabola?
yanalaym [24]

First we have to understand what the domain is. In a nutshell the domain is the set of all x values that are represented in any given graph. In this case we do not have a graph but we have the vertex. The x value is 2, therefore: x ≥ 2.


I hope this helps, Regards.

Find the slope of the line on the graph.write your answer as a fraction or a whole number, not a mixed number
Leona [35]

Answer:

slope = -\frac{1}{2}     if it were in an

Step-by-step explanation:

the graph is a negative and will therefore have a negative slope. to find the slope, pick a point on the graph and find the \frac{rise}{run}.

for instance, start with the point (0,1). Then go down 1 and left 2 to get to the next point on the graph (2,0). 1 is the "rise" and 2 is the "run" hence -1/2 being the slope.

you could also use the slope formula: \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

point 1: (0,1)    (x₁ ,y₁)

point 2: (2,0)    (x₂ , y₂)

\frac{0-1}{2-0} =-\frac{1}{2}

Using the image above, what is the measure of Side AC? Round to the nearest hundredth
Evgesh-ka [11]

To solve this problem, we just have to use trigonometric ratios and apply which of the ratios is needed here and proceed to solve. The value of side AC is 2.85 units

<h3>Trigonometric Ratio</h3>

In the given diagram, we have the value of angle and hypothenuse and we are required to find the adjacent side of the triangle.

Data;

  • Angle = 32.9 degrees
  • Hypothenuse = 3.4

Let's use cosine rule for this.

cos\theta = \frac{adjacent}{hypothenuse}

Proceed to substitute the values into the equation and solve.

cos 32.9 = \frac{AC}{3.4} \\AC=3.4cos32.9\\AC = 2.85

From the calculations above, the value of side AC is 2.85 units

2x + 5= 12 <br> whats x?
nignag [31]

Answer:

x = 7/2 = 3 1/2

Step-by-step explanation:

2x + 5= 12

Subtract 5 from each side

2x + 5-5= 12-5

2x = 7

Divide each side by 2

2x/2 =7/2

x = 7/2

Changing from an improper fraction to a mixed number

2 goes into 7 3 times with 1 left over

x = 3 1/2
