Answer:

\boxed{A. (1,1)}

Step-by-step explanation:

Well since in,

f(x) = -3x^2 + 6x - 2

the 3x^2is negative that means the parabola has a maximum not a minimum meaning we can take out choices,

B and D.

To find the maximum let’s graph the given equation,

Look at the image below.

By looking at the image we can tell that the maximum is at (1,1).

So the answer is choice A (1,1)

Katherine is landscaping her home with juniper trees and pansies. She wants to arrange 15 pansies around each of 8 trees. Each t
Tom [10]

The mathematical expression that Katherine requires to know the price of the objects that she is going to buy is 8 * ($20.75) + 120 * ($5/12) = $216

<h3>How to write an expression for this procedure?</h3>

To find a mathematical expression for this procedure we must take into account the values that we know.

For example, we know that it requires 15 pansies for each tree. This can be expressed like this:

  • 15 * 8 = 120 pansies.

On the other hand, we must calculate the price of each tree and the pansies that are going to be used to surround each one as shown below.

  • Cost of trees = 8 * $20.75
  • Pansies Cost = 15 * ($5/12)

According to the above, the final expression, in which all the necessary data for Katherine is included, is:

  • 8 * ($20.75) + 120 * ($5/12) = $216

The height of a trapezoid is 26 yards and the bases are 14 and 30 yards. What is the area (in square yards)?
faust18 [17]

Answer: 572 yards

Step-by-step explanation:

The equation to find the area of a (base1 + base2) x height/2

The two bases are 14 and 30. Add them up to get 44.

Then, times that by the height. You get 1,144.

Lastly, divide 1,144 by 2. You get 572.

I hope this helped!

A 150-N bird feeder is supported by three cables. Find the tension in each cable.
Irina-Kira [14]
X axis : -t1 cos 60 + t2 cos 60 = 0
 
            t2 cos 60   = t1 cos 60    ; t2   = t1

Y axis : t1 sin 60  + t2 sin 60 - 150 = 0

since t2 = t1

2t1 sin 60 =  150

t1 ( sqrt(3)/2)  = 150/2

t1   = 50 [sqrt(3)]

t2 = 50 [sqrt(3)]

t3 = 150 N

hope this helps
