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

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

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
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

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
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.

Answer:
Amount of Niobium-91 initially
= 300/91 =3.2967mol
2040 years = 3 ×680 = 3 half-lives
therefore, amount left = 0.4121mol

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?
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.

Step-by-step explanation:
using the identity
tan²x = sec²x - 1
consider the left side
(tanx + secx)² ← expand using FOIL
= tan²x + 2tanxsecx + sec²x
= sec²x - 1 + 2tanxsecx + sec²x ← collect like terms
= 2sec²x + 2tanxsecx - 1

Answer:
You would do this problem like a normal varible problem. x=10
Step-by-step explanation:
Since 9x is a right angle the inside would also be 9x
9x+4x+10+40=180
180 because that is how much a triangle equals
combine like terms
13x+50=180
subtract 50 from both sides
13x=130
divide by 13
x=10
