Answer:

\Huge \boxed{-2}

Step-by-step explanation:

f(x)=-2x^2-2x+10

For f(2), the input of the function is 2.

Let x = 2.

f(2)=-2(2)^2-2(2)+10

Evaluate.

f(2)=-2(4)-2(2)+10

f(2)=-8-4+10

f(2)=-2

Answer:

f(x) =  - 2 {x}^{2}  - 2x + 10

put the value of x = 2

f(2)  =  - 2( {2}^{2} )  - 2(2) + 10

f(2)  =  - 8 - 4 + 10

f(2) =  - 12 + 10

f(2) =  - 2

2 angles measure 40 degrees each, what does the third angle measure? what type of triangle is it?
zimovet [89]

Answer:

Part a): 100 degrees

Part b): Isosceles Triangle

Step-by-step explanation:

Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.

180 - 80 = 100

Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.

Arc Length: The pendulum on a grandfather clock swings from side to side once every second. If the length of the pendulum is 4 f
Karolina [17]
Imagine the path of the tip of the pendulum as an arc of a circle. The circle would have a radius of 4 feet and the arc would be 20 degrees. To calculate the length of the arc, you need to find 20 degrees of the circumference. 

Length of Arc = 2*pi*R*Degree of arc/360 
Length of Arc = 2*pi*4*20/360 
Length of Arc = 8pi * 1/18 
Length of Arc = 4/9 pi feet 
<span>Length of Arc ~ 1.396263402 feet 

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

A graph of a quadratic function y = f(x) is shown below.
spin [16.1K]

We are given a graph of a quadratic function y = f(x) .

We need to find the solution set of the given graph of a quadratic function .

<em>Note: Solution of a function the values of x-coordinates, where graph cut the x-axis.</em>

For the shown graph, we can see that parabola in the graph doesn't cut the x-axis at any point.

It cuts only y-axis.

Because solution of a graph is only the values of x-coordinates, where graph cut the x-axis. Therefore, there would not by any solution of the quadratic function y = f(x).

<h3>So, the correct option is 2nd option :∅.</h3>
