Answer:

f (x) = (x-4)(x + 5)^2(x-9)(x+7)

Step-by-step explanation:

The zeros of the polynomial are all the values of x for which the function f (x) = 0

In this case we know that the zeros are:

x = 4,\ x-4 =0

x = 9,\ x-9=0

x = -5, x + 5 = 0 (multiplicity 2)

x = -7,\ x+7=0

Now we can write the polynomial as a product of its factors

f (x) = (x-4)(x + 5)^2(x-9)(x+7)

Note that the polynomial is of degree 5 because the greatest exponent of the variable x that results from multiplying the factors of f (x) is 5

Identify the domain and range of each of the graphs below.<br><br><br> Domain: <br><br><br> Range:
Anna11 [10]

Answer:

Domain → (-∞, ∞)

Range → (-∞, ∞)

Step-by-step explanation:

Domain of a function is defined by the x-values or input values of the graph.

Similarly, Range of the function is defined by the y-values or output values from the graph.

From the picture attached,

x - values for the line shown in the graph vary from negative infinity to positive infinity.

Therefore, Domain of the function will be → (-∞, ∞)

And for every x-value there is a y-value, so Range of the function will be same as domain (varying from negative infinity to positive infinity) → (-∞, ∞)

Answer:

First one.

Step-by-step explanation:

0.3/3=0.1 ==> 0.1$ per meter

0.77/7 ==> 0.11$ per meter

The first option is cheaper, therefore better to buy if you agree with "the cheaper. the better".

A jet is coming in for a landing. It's currently 25,000 feet in
Mariana [72]

The angle of depression is 29.0521°. So it is a safe landing.

Step-by-step explanation:

Step 1:

The plane is flying at a height of 25,000 feet and 45,000 feet away from the landing strip. Assume it lands with an angle of depression of x°.

So a right-angled triangle can be formed using these measurements. The triangle's opposite side measures 25,000 feet while the adjacent side measures 45,000 feet. The angle of the triangle is x°.

To determine the value of x, we calculate the tan of the given triangle.

tanx = \frac{opposite side}{adjacent side}.

Step 2:

The length of the opposite side = 25,000 feet.

The length of the adjacent side = 45,000 feet.

tan x = \frac{25,000}{45,000} = 0.5555.

So x = 29.0521°. Since x < 30°, it is a safe landing.

The sum of two consecutive integers is -239 find the two integers​
xenn [34]

Answer:

The two consecutive integers are -119 and -120

Step-by-step explanation:

As we know that these two integers are consecutive, that means that they will have a difference of 1. This means that we can find the two integers by adding 1 to the sum of -239 and then dividing it by two

1-239=-238\\\frac{-238}{2} =-119\\-119-1=-120
