A dog is tied with a rope to a stake in the ground. The length of the rope is 10 yards.
serg [7]

Answer:

the area in square yards is 100πyd^2

Step-by-step explanation:

The computation of the area is shown below:

Area = πr^2

= π10^2

= 100πyd^2

Hence, the area in square yards is 100πyd^2

We simply applied the above formula to determine the area

An angle measures 14° more than the measure of its supplementary angle. What is the measure of each angle?
luda_lava [24]

Answer:83 and 97

Step-by-step explanation:

Let the angle be y

The second angle will be y+14

A supplementary angle equals 180°

y + y + 14=180

2y+14=180

2y=180-14

2y=166

y=166/2

y=83

The first angle is 83.

Second angle will be 83+14=97.

Use the Parabola tool to graph the quadratic function. f(x)=2x^2−12x+19 Graph the parabola by first plotting its vertex and then
Debora [2.8K]
To find the vertex of our parabola, we are going to use the vertex formula: For a quadratic of the form f(x)=x^2+bx+c it vertex (h,k) is given by h= \frac{-b}{2a}, k=f(h).
We can infet from our parabola that a=2 and b=-12. So lets replace those values in our formula:
h= \frac{-b}{2a}
h= \frac{-(-12)}{2(2)}
h= \frac{12}{4}
h=3
k=f(h)=2(3)^2-12(3)+19
k=2(9)-36+19
k=18-17
k=1
The vertex (h,k) of our parabola is (3,1)

Now to find our second point, we are going to evaluate our parabola at x=0
f(0)=2(0)^2-12(0)+19
f(0)=0+0+19
f(0)=19
Our second point is (0,19)

We can conclude that we can graph the parabola f(x)=2x^2-12x+19 using its vertex (3,1) and the point (0,19) as follows:
