H(n) = n^2 - 4n; Find h(-3)

Mathematics
2 answers:
k0ka [10]3 years ago
7 0

For this case we have the following function:

h (n) = n ^ 2-4n

We must find the value of the function when n = -3.

Substituting we have:

h (-3) = (- 3) ^ 2-4 (-3)

We must bear in mind that the law of multiplication signs complies:

- * - = +

So:

h (-3) = 9 + 12\\h (-3) = 21

Answer:

h (-3) = 21

Answer:

h(-3)= (-3)^2 - 4(-3)

9+12= 21

What is the value of X?
alexandr402 [8]

Answer:

x = 45

Step-by-step explanation:

The 3 angles of a triangle add up to 180

<a + <b + <c = 180

substitute what you know

55+ 80 + <c = 180

combine like terms

135 + <c = 180

subtract 135 from each side

<c = 180 -135

<c = 45

x = 45

The diagram below gives the dimensions of a swimming pool. 18 ft , 20ft, 36ft (c) What is the total area of the swimming pool? E
WARRIOR [948]
The picture in the attached figure

Part 1) <span>What is the total area of the swimming pool?
</span>
we know that
<span>area of the swimming pool=area rectangle-area semi circle

area rectangle=20*36-----> 720 ft</span>²

area semicircle=pi*r²/2
r=18/2----> 9 ft
area semicircle=pi*9²/2----> 127.17 ft²

area of the swimming pool=720 ft²-127.17 ft²----> 592.83 ft²

the answer Part 1) is
The area of the swimming pool is 592.83 ft²

Part 2) <span>What is the perimeter of the swimming pool?
</span>
perimeter of the swimming pool=perimeter of rectangle-18 ft+perimeter semi circle
perimeter of rectangle=2*[20+36]---> 112 ft

perimeter semi circle=2*pi*r/2----> pi*r
r=9  ft
perimeter semi circle=pi*9----> 28.26 ft
 so
perimeter of the swimming pool=112 ft-18 ft+28.26 ft----> 122.26 ft

the answer Part 2) is
122.26 ft

Would this expression:
Ratling [72]

The given expression is a perfect square trinomial.

<h3>How to classify the given expression?</h3>

Here we have the expression:

(x^2 - 16)^2

Notice that we can rewrite it as:

(x^2 - 4^2)^2

Then we can see that inside the parenthesis we have a difference of squares, but it is squared, so if we define:

x^2 = a\\4^2 = b

We will have:

(a - b)^2 = a^2 + -2ab + b^2 = (x^2)^2 - 2*(4^2)*(x^2) + (4^2)^2

Which is in fact, a perfect square trinomial.
