Answer:
21
Step-by-step explanation:
Try using this notation: a(n) and not an.
an=n^3-2n becomes a(n) = n^3 - 2n.
Then a(1) = 1^3 - 2(1) = 1 - 2 = -1
a(2) = 2^3 - 2(2) = 8 - 4 = 4
a(3) = 3^3 - 2(3) = 27 - 6 = 21

An ice chest contains 4 cans of apple juice, 6 cans of grape juice, 4 cans of orange juice, and 6 cans of mango juice. Suppose that you reach into the container and randomly select three cans in succession. Find the probability of selecting three cans of grape juice.
Answer:
3/20
Step-by-step explanation:
probability = Number of favourable outcomes÷Total number of outcomes
total outcomes =20 juice cans
Number of favourable outcomes =3cans of grape juice
Therefore P(E)=3÷20
Probability=3/20
=3/20

Write a polynomial that represents the perimeter of the triangle with side lengths x+3, x^2+3x+7, 4x^2-9x+12
Answer:
The polynomial that represents the perimeter of the triangle is 5x^2-5x +22.
Step-by-step explanation:
Perimeter of the triangle= a+b+c where a,b,c are the length of the sides of the triangle.
Given
a= x+3, b= x^2+3x+7, c= 4x^2-9x+12
Perimeter of the triangle = x+3 + x^2+3x+7+ 4x^2-9x+12
= 5x^2-5x +22
The polynomial that represents the perimeter of the triangle is 5x^2-5x +22.
A polynomial is an expression which has variables , constants and terms and exponents combined with addition subtraction etc.
Example 5x^2-5x +22 is a polynomial.
It has exponent, variables and constant .

Step-by-step explanation:
I need a expert I need the area of the square the smaller triangle and the bigger triangle
Answer:
small triangle area = 1/2(8)(14) = 56 m²
bigger triangle area = 1/2(16)(14) = 112 m²
biggest triangle area = 1/2(24)(14) = 168 m²
there's 2 bigger triangles so you pick the bigger one you want
Answer:
smaller triangle area = 56m²
larger triangle area = 112m²
total area = 168m²
Step-by-step explanation:
Area of triangle = [tex]\frac{bh}{2}[/tex]
where b = base length and h = height
smaller triangle dimensions
base length= 8m
height = 14m
* plug in the values into the formula *
[tex]area=\frac{8*14}{2} \\8*14 =112\\\frac{112}{2}=56\\A=56m^2[/tex]
so we can conclude that the area of the smaller triangle is 56 square meters
larger triangle dimensions
base length = 16m
height = 14m
* plug in the values into the formula *
[tex]area=\frac{16*14}{2} \\16*14=224\\\frac{224}{2} =112\\A=112m^2[/tex]
so we can conclude that the area of the larger triangle is 112 square meters
total area = the sum of the two triangle's area
total area = 112 + 56
112 + 56 = 168
hence the total area is 168 square meters

c. Write part (a) & (b) as ordered pairs.
Answer:
f(0) = 7 f(-2) = 15 (7,15)
Step-by-step explanation:
f(0) = -4(0) + 7 = 7
f(-2) = -4(-2) + 7 = 15

What does a low interest rate indicate?
A poor salary
Increased risk
A higher credit score
Zero loan fees
9514 1404 393
Answer:
A higher credit score
Step-by-step explanation:
Interest rates are generally set based on at least a couple of factors:
what the market will bear (competition)the risk associated with a loanFolks who have a lower level of disposable income, or who have a history of missed payments or loan defaults are likely to have a lower credit score. Loans offered will likely have a higher interest rate than for someone with a better credit score.
Loan fees may be reduced also when interest rates are reduced.
Based on the above discussion, we see that lower loan fees, higher credit score, and lower interest rates are all positively correlated. One does not necessarily indicate another.
Of the choices offered, we suppose "a higher credit score" is most likely the desired answer.
Answer:
A higher credit score
Step-by-step explanation:
Remember, you can only get low interest rate if you have a high credit score.

Simplify the expression:
-3.5i -4h +22 -0.3h +4.6i
Answer:
[tex]22 + 1.1 \times i - 4.3h[/tex]
Step-by-step explanation:
1) Collect like terms.
[tex]22 + ( - 3.5i + 4.6i) + ( - 4h - 0.3h)[/tex]
2) Simplify.
[tex]22 + 1.1 \times i - 4.3h[/tex]
hence, the answer is 22 + 1.1 × i - 4.3h.

Answer:
x = 12
y = 6√3
Step-by-step explanation:
✅Apply the intersecting secant theorem to find x. Thus:
6(6 + x) = 7(7 + 8³/7)
Convert the mixed fraction to improper fraction
6(6 + x) = 7(7 + 59/7)
36 + 6x = 49 + 59
36 + 6x = 108
6x = 108 - 36
6x = 72
Divide both sides by 6
x = 72/6
x = 12
✅Apply the tangent-secant theorem to find y. Thus:
y² = 6(6 + x)
Plug in the value of x
y² = 6(6 + 12)
y² = 6(18)
y² = 108
y = √108
y = 6√3
