Answer:
[tex] {a}^{2} + a - 6[/tex]Step-by-step explanation:
[tex](a + 3)(a - 2)[/tex]
Multiply the second parentheses by each term from the first parentheses
[tex] = a(a - 2) + 3(a - 2)[/tex]
Distribute ' a ' through the parentheses
[tex] = {a}^{2} - 2a + 3(a - 2)[/tex]
Distribute 3 through the parentheses
[tex] = {a}^{2} - 2a + 3a - 6[/tex]
Collect like terms
[tex] = {a}^{2} + a - 6[/tex]
Hope this helps..

Answer:
The midpoint is (2.5, 3.5)
Step-by-step explanation:
The midpoint is the average of the coordinates
x = (x1+x2)/2 and y =(y1+y2)/2
x = (2+3)/2 = 5/2 = 2.5
y = (3+4)/2 = 7/2 = 3.5
The midpoint is (2.5, 3.5)
Answer:
(2.5, 3.5)
Step-by-step explanation:
The midpoint is found by taking the average of the x-coordinates and the average of the y-coordinates.
Here, the average of the x-coordinates is (2 + 3)/2 = 5/2 = 2.5.
The average of the x-coordinates is (3 + 4)/2 = 7/2 = 3.5.
The answer is thus (2.5, 3.5).

The Credit Score helps us to
Quickly paying off debts and Having long-standing lines of credit.
What is Credit Score?Based on information from your credit reports, a credit score predicts your credit behavior, such as how likely you are to repay a loan on time.
This is determined by the total amount you owe, the variety and quantity of accounts you have, and the ratio of your debt to your available credit.
Given:
As, Smaller amounts may boost your credit score if you make on-time payments, but larger balances and maxed-out credit cards will lower it.
So, Credit Score usually used to pay the debts.
But the debts are bad for credit.

Another math question I couldn't figure out.
(I did actually figure out an answer for this one, but it's definitely wrong.)
Each year the value of a bank account increases by 3% because of interest.
If £700 is paid into the account and no money is paid in or taken out, how much will be in the account after 3 years?
I believe the answer is 764.90. 3% of 700 is 21, then add that to 700- have three percent of that- add it to the 721, find 3% of that, then three percent of that then add that to 700 :)

Which form of a quadratic function is easiest to use when finding the maximum or minimum value of the function?
Answer:
ax² + bx + c
Step-by-step explanation:
The form of a quadratic equation that is easy to use when finding the maximum or minimum value of the function is ax² + bx + c.
Suppose a quadratic function:
f(x) = 2x² - 8x + 9
Use ( -b/2a , f(-b/2a) ).
-b/2a
a = 2
b = -8
-(-8)/2(2)
8/4
= 2
f(2) = 2(2)² - 8(2) + 9
f(2) = 2(4) - 8(2) + 9
f(2) = 8 - 16 + 9
f(2) = 1
The minimum value of this quadratic function is (2, 1).
It represents a minimum value because a > 0.
Answer:
Vertex form
Step-by-step explanation:
There are several forms of the quadratic equation
Standard form: y = ax^2 + bx + c which is useful for the quadratic equation and the axis of symmetry
Factored form: y = (ax - c)(bx - d) which will give us the zeros
and
Vertex form: y = a(x - h)2 + k where ( h,k) is the vertex
The maximum and minimum would be the value of k
It would be maximum when a >0 and minimum when a<0

Step-by-step explanation:
Given the points J (1,-10) and K (7, 2)
From the section formula
[tex](x,y)=\left(\dfrac{mx_2+nx_1}{m+n}, \dfrac{my_2+ny_1}{m+n}\right)[/tex]
The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is obtained using the formula:
[tex]y=\dfrac{my_2+ny_1}{m+n}\\m=5, n=1, y_1=-10, y_2=2\\Therefore:\\y=\dfrac{5*2+1*-10}{5+1}\\=\dfrac{10-10}{6}\\=0[/tex]
The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.
The y coordinate of the point that divides J to K in the ratio 5 : 1 is 0.
DistanceIf a point O(x, y) divides the line segment AB with end points A(x₁, y₁) and B(x₂, y₂) in the ratio n:m, the coordinate of O is:
[tex]x=\frac{n}{n+m} (x_2-x_1)+x_1\\\\y=\frac{n}{n+m} (y_2-y_1)+y_1[/tex]
Let O(x, y) represent the point dividing J to K in the ratio 5 : 1. K(7,2) and J(1, -10)Hence:
[tex]y=\frac{5}{5+1}(2-(-10)) + (-10)=0[/tex]

What's the equation of the parabola that has its vertex at (8,–14) and a point (5,13) that lies on the curve?
Question 13 options:
A)
y = (x + 8)2 – 14
B)
y = (x – 8)2 – 14
C)
y = 3(x + 8)2 – 14
D)
y = 3(x – 8)2 – 14
Answer:
The expression with the described characteristics is: [tex]y = 3*(x - 8)^2 - 14[/tex]. Therefore the correct answer is letter D.
Step-by-step explanation:
I believe there is a typo in the vertex's coordinate, I think it should be (8,14). I came to this conclusion by observing the possible answers, if the given vertex is correct then there are no correct answers among them. I made my best effort to explain the question in a way that can be generalized for different vertex's coordinates.
The equations are given in their vertex form. This form has the following structure:
[tex]y = a*(x - h)^2 - k[/tex]
Where (h,k) are the vertex's coordinates, in our case (8, 14). This knowledge makes easier to determine a equation with the correct vertex as shown below:
[tex]y = a*(x - 8)^2 - 14[/tex]
Where the value of "a" must be determined by applying the given point.
[tex]13 = a*(5 - 8)^2 - 14\\13 = a*(3)^2 - 14\\a*9 = 27\\a = \frac{27}{9}\\a = 3[/tex]
The expression with the described characteristics is: [tex]y = 3*(x - 8)^2 - 14[/tex]. Therefore the correct answer is letter D.

What is the linear function defines the following Arithmetic Sequence? -5, -3, -1, 1, 3, ...
a. an = -5 + 2(n - 1)
b. an = -5 - 2(n - 1)
c. an = 5 - 2(n - 1)
d. an = 5 + 2(n - 1)
Answer:
an = -5 + 2( n-1)
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+ d ( n-1)
where a1 is the first term and d is the common difference
a1 = -5 since it is the first term in the sequence
d = term 2 minus term1
= -3 - (-5)
= -3+5 = 2
an = -5 + 2( n-1)

Applying Pythagoras' Theorem,
(adjacent side)²= 18² -9²
adjacent side[tex] = \sqrt{243} [/tex]
adjacent side= 15.588 m (5 s.f.)
Area of triangle= ½ ×base ×height
Area of traingle

Find the value of x. Give reasons to justify your solution. C ∈ AE
Answer:
x = 11º
Step-by-step explanation:
1. Notice Parallel Lines
2. Understand Angle Relationships When Parallel Lines Are Present (e.g., alternate interior/exterior)
3. ∠CAB ≅ ∠DCA ∴ m∠CAB = 33º
4. Use exterior angle theorem: the sum of non-adjacent angles of the same triangle which the exterior angle is drawn is equal to the measure of that angle.
5. Therefore write and solve the equation 2x + 33º (sum of non-adjacent interior angles) = 5x (exterior angle).
2x + 33 = 5x (C.L.T or Combine Like Terms)3x = 33 (inverse operations; divide by 3)x = 11º (remember to apply units)Answer:

Answer:
uppercase B = StartFraction 3 uppercase V Over h

The formula for the volume (V) of a pyramid is:
V = 1/3*B*h
where B is the are of the base and h is the height. We can isolate B, as follows:
multiply by 3 at both sides
V*3 = 1/3*B*h*3
divide by h at both sides
V*3/h = B*h/h
V*3/h = B

c) to nearest 0.001

The question is incomplete.
Complete Question
Correct 36.2598 to
a) to one decimal place.
b) To the nearest hundredth.
c) to nearest 0.001
d) to the nearest whole number
Answer:
a) to one decimal place = 36.3
b) To the nearest hundredth= 36.26
c) to nearest 0.001 = 36.260
d) to the nearest whole number = 36
Step-by-step explanation:
From the question, we are to round up 36.2598 to the following:
a) to one decimal place.
Rounding up 36.2598 to one decimal place means we are looking at the first number after the decimal which is 2. The number after it is 5, so we are adding one to 2. Hence,
36.2598 to one decimal place = 36.3
b) To the nearest hundredth:
Rounding up 36.2598 to the nearest hundredth means we are rounding up to 2 decimal places. This means we are looking at the second number after the decimal which is 5. The number after it is 9, which is higher than 5 so we are adding one to 5. Therefore,
36.2598 to the nearest hundredth = 36.26.
c) to nearest 0.001
Rounding up 36.2598 to the nearest 0.001 means we are rounding up to the nearest thousandth which is 3 decimal places.
This means we are looking at the third number after the decimal which is 9. The number after it is 8, which is higher than 5 so we are adding one to 9.
Therefore,
36.2598 to the nearest 0.001 = 36.260
d) to the nearest whole number
Rounding up 36.2598 to the nearest whole number means we are rounding up the number before the decimal place. That number is 6. We look at the first digit after the decimal, it is less than 5, 6 remains unchanged, if it is 5 and above, we add one to 6.
For our question, the number after the decimal is 2, it is less than 5 so 6 remains unchanged.
36.2598 to the nearest whole number = 36.
