If x = 5 units, y = 15 units, and h = 8 units, find the area of the parallelogram shown above using decomposition. OA. 120 square units OB. 40 square units OC. 160 square units OD. 80 square units​

Answers

Answer:

160 square units

Step-by-step explanation:

First, lets focus on the triangles.

To find the area of a right triangle, we need to multiply the length by the width, and divide by 2.

(5 * 8) / 2 = 20

(And since there is two triangles, the area of the two is 40.)

To find the area of a rectangle, we need to multiply the length by the width.

15 * 8 = 120

Now we add all the areas together.

120 + 20 + 20 = 160

Is the answer is 160 square units.

consider the left side

(tanx + secx)² ← expand using FOIL

= tan²x + 2tanxsecx + sec²x

Since the shape is a parallelogram, there are 2 pairs of opposite but equal sides --> "6a+21" and "20a+7"                   "11a" and "4a+7"

The easier pair is

11a = 4a+7              Subject 4a from both sides

7a = 7                     Divide 7 from both sides

a = 1

A = 1

The sum of the first five terms of this sequence is 228
Work out the value of a,

Answers

We will see that the value of a is 12.

How to get the value of a?

We have a Fibonacci sequence, and the first four terms are:

a, 2a, 3a, 5a.

Because it is a Fibonacci sequence, the next term should be the sum of the two previous ones.

3a + 5a = 8a

Then the sum of the first 5 terms is:

(a + 2a + 3a + 5a + 8a) = 228

We can solve this for a.

(1 + 2 + 3 + 5 + 8)*a = 228

19*a = 228

a = 228/19 = 12

So we conclude that the value of a is 12.

Answers

Answer:

Amount of Niobium-91 initially

A dressmaker needs to cut 9-inch pieces of ribbon from rolls of ribbon that are 9 feet in length. How many 9-inch pieces can the dressmaker cut from 5 of these rolls of ribbon?

Answers

Answer:

20 pieces

Each roll has 36 inches of ribbon. This means that 5 rolls have 180 inches of ribbon (5 x 36 = 180).

You can then divide the 180 by 9 to find out how many 9 inch pieces the dressmaker can cut from 5 rolls of ribbon.

Equation representation:

36 inches x 5 rolls = 180 inches in total
(one roll)

180 inches ÷ 9 = 20 peices

In conclusion, the dressmaker can cut 20, 9-inch pieces from 5 rolls of ribbon.

Which equation for g(x) represents the transformation of f(x) given that f(x) = x^2
g(x) = f(x) shifted up 2 units
i have more translation of quadratics questions i need some help on so if you’re willing let me know

Answers

Answer:

g(x) = x² + 2

Step-by-step explanation:

If we want to shift a function down, we subtract the number we are asked to move outside the function's argument:

⇒ To shift f(x) b units down → f(x) - b

Similarly, in function notation, if we want to shift a function up, we add the number we are asked to move outside the function's argument:

⇒ To shift f(x) b units up → f(x) + b

Given function f(x) = x²

Shift 2 units up ⇒ x² + 2

Therefore, g(x) = x² + 2
