Answer:

<h2>The function f(x) = (x - 6)(x - 6) has only one x-intercept. But at (6, 0) not at (-6, 0).</h2>

Step-by-step explanation:

The intercept form of a quadratic equation (parabola):

y=a(x-p)(x-q)

p, q - x-intercepts

Therefore

The function f(x) = x(x - 6) = (x - 0)(x - 6) has two x-intercepts at (0, 0) and (6, 0)

The function f(x) = (x - 6)(x - 6) has only one x-intercept at (6, 0)

The function f(x) = (x + 6)(x - 6) = (x - (-6))(x - 6)

has two x-intercept at (-6, 0) and (6, 0)

The function f(x) = (x + 1)(x + 6) = (x - (-1))(x - (-6))

has two x-intercepts at (-1, 0) and (-6, 0).

An animal shelter spends $5.50 per day to care for each bird and $8.50 per day to care for each cat. Nicole noticed that the she
aliina [53]

Answer: 19 birds were at the shelter on Wednesday.

Step-by-step explanation:

Let x represent the number of birds that were at the shelter on Wednesday.

Let y represent the number of birds that were at the shelter on Wednesday.

Nicole found a record showing that there were a total of 40 birds and cats on Wednesday. This means that

x + y = 40

The animal shelter spends $5.50 per day to care for each bird and $8.50 per day to care for each cat. Nicole noticed that the shelter spent $283.00 caring for birds and cats on Wednesday. This means that

5.5x + 8.5y = 283 - - - - - - - - - - - - - -1

Substituting x = 40 - y into equation 1, it becomes

5.5(40 - y) + 8.5y = 283

220 - 5.5y + 8.5y = 283

- 5.5y + 8.5y = 283 - 220

3y = 63

y = 63/3 = 21

x = 40 - y = 40 - 21

x = 19

Can I please get some help
Aleksandr [31]

Answer:

a. 1.76

b. 2.5

Step-by-step explanation:

You have the following formula given in the exercise:

t=\frac{\sqrt{100-h}}{4}

a. If the object is 50 feet above the ground, you can identify that the value of the variable "h" would be the following:

h=50

Then, knowing that value, you can substitute it into the given formula and then evaluate in order to calculate the time in seconds for the object to be 50 feet above the ground.

This is:

t=\frac{\sqrt{100-50}}{4}\\\\t=1.76

b. When the object reaches the ground, the value of "h" is:

h=0

Therefore, substituting this value into the formula and evaluating, you get that time (in seconds) it takes to the object reaches the ground is:

t=\frac{\sqrt{100-0}}{4}\\\\t=2.5
