Mathematics
1 answer:
Nataly [62]2 years ago
3 0

Answer:

Step-by-step explanation:

x^2-9 = 0

x^2 = 0+9

x^2=9

Take square root  at both sides:

√x^2 =+/-√9

x =+/- 3

This equation has 2 real solutions, x=3 , x=-3....

Tadeo is a beekeeper. The table shows the weekly number of bees producing honey in a new hive. Which expression gives the number
Afina-wow [57]

The exponential equation that gives the number of bees in week 12 is of:

y = 4(3)^{11} = 708588

<h3>What is an exponential function?</h3>

It is modeled by:

y = ab^x

In which:

  • a is the initial value.
  • b is the rate of change.

In this problem, considering that the initial week is the first, and the value triples every week, the expression for the number of bees after x weeks is given by:

y = 4(3)^{x - 1}

Hence, after 12 weeks, the expression is:

y = 4(3)^{11} = 708588

Complete the square to rewrite y = x2 - 6x + 3 in vertex form. Then state
Vladimir [108]

Answer:

see explanation

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

y = x² - 6x + 3

To complete the square

add/subtract ( half the coefficient of the x- term)² to x² - 6x

y = x² + 2(- 3)x + 9 - 9 + 3

  = (x - 3)² - 6 ← in vertex form

• If a > 0 then vertex is a minimum

• If a < 0 then vertex is a maximum

Here a = 1 > 0, thus

(3, - 6 ) is a minimum
