On a coordinate plane, a curved line with a minimum value of (5.1, negative 7) and a maximum value of (0, 25), crosses the x-axi
liubo4ka [24]

Answer:

<u>The true statement is D</u>

Step-by-step explanation:

The rest of the question is the attached figure and the statement options.

  • A. Over the interval [–4, –2], the local minimum is 0.
  • B. Over the interval [–2, –1], the local minimum is 25.
  • C. Over the interval [–1, 4], the local minimum is 0.
  • D. Over the interval [4, 7], the local minimum is -7.

============================================================

According to the graph, we will check the options:

A. Over the interval [–4, –2], the local minimum is 0.  (<u>Wrong</u>)

Because the minimum is -12

B. Over the interval [–2, –1], the local minimum is 25.   (<u>Wrong</u>)

Because the minimum is 18

C. Over the interval [–1, 4], the local minimum is 0.  (<u>Wrong</u>)

Because the minimum is at x = 4 less than zero

D. Over the interval [4, 7], the local minimum is -7.    (<u>True</u>)

The next two systems do NOT have opposite like terms ​
Sindrei [870]

Answer:

x = 10

y = 6

Step-by-step explanation:

Multiply second equation with -1 and then add it up with first equation

(-1)*(6x - 7y) = 18

-6x + 7y = -18

6x - 6y - 6x + 7y = 24 - 18 add like terms

y = 6 to find the value of x use this information

6x - 6y = 24 replace y with 6

6x - 6*6 = 24

6x - 36 = 24 add 36 to both sides

6x = 60 divide both sides by 6

x = 10

The base of a regular hexagonal pyramid has an apothem length of 3√ in. What is the exact area of the base of the pyramid?
12345 [234]
1. To solve this problem you must apply the formula for calculate the area of a regular hexagon given the apothem, which is shown below:

 A=(Perimeter x Apothem)/2

 2. You have the apothem, so you can calculate the perimeter. First, you have to know the lenghts of the sides:

 Tan(30°)=x/√3
 x=1

 Side=2x
 Side=2

 Perimeter=2x6
 Perimeter=12

 3. Then, you have that the area of the base is:

 A=(Perimeter x Apothem)/2
 A=12x√3/2
 A=6√3
 A=10.39
 B=10.39 cm²

 The answer is: B=10.39 cm²
