Write a quadratic function h whose zeros are - 6 and -5 h (x) =​
ANTONII [103]

Answer:

h(x)= x^2+11x+30

Step-by-step explanation:

A quadratic function is in the form h(x) = ax^2 + bx + c.

Since the zeros are -6 and -5, take the opposite signs and add them to the variable x separately.

It should look like this: h(x)= (x+6)(x+5)

Since this is the factored form, we have to solve this equation further.

h(x)= (x+6)(x+5)

h(x)= x^2+6x+5x+30

h(x)= x^2+11x+30

A rectangular yard is 20 yards wide and 40 yards long. It is surrounded by a thick hedge that grows on the border of the propert
borishaifa [10]

Answer:

W_{h}= 4.275yd

Step-by-step explanation:

Data

wide=20yd

length=40yd

Hedge area  A_{h}=171yd^{2}

If the area of rectangle is A=base * hight and our case L*W. then:

A_{h}=171yd^{2}=40yd*W_{h}

So W_{h}=\frac{A_{h} }{L} =171yd^{2}/40yd=4.275yd

Which of the following inequalities has no solutions?
neonofarm [45]

Answer:

  • A) x > 3 and x < 2 has no solutions

Step-by-step explanation:

Given inequalities below and we are looking for a pair with no solution.

Let's verify:

A) x > 3 and x < 2,

  • It has no solutions since the two inequalities have no common interval.

B) x > - 3 and x < - 2,

  • Its solution is -3 < x < - 2, the interval between two given endpoints.

C) x > - 3 and x < 2,

  • Similar to option B, the interval is between two endpoints:
  • - 3 < x < 2

D) x > - 3 and x > - 2,

  • Its solution is x > - 2, the two inequalities cover almost same interval.
