Mathematics
1 answer:
matrenka [14]4 years ago
7 0

Answer:

Step-by-step explanation:

a(n) = n² - 3n - a(n-1) and a(1) = 4

We have a(1) = 4 and want a(2) (for which n = 2).

a(2) = 2² - 3(2) - a(2-1)  →  a(2) = 4 - 6 - 4 = -6 = a(2)

a(3) = 3² - 3(3) - (-6) = 9 - 9 + 6 = 6 = a(3)

a(4) = 4² - 3(4) - 6 = 16 - 12 - 6 = -2 = a(4)

a(5) = 5² - 3(5) + 2 = 12 = a(5)

A rectangle has an area of 96 cm2 The length of the rectangle is 4 cm longer than the width. Work out the length and width of th
Svetach [21]
Area of a rectangle: 2(L+W)
length: 4+W

Area: 2(4+W) + 2W = 96
8+2W+2W = 96
8+4W = 96
4W = 88
W= 22cm

Calculate for length: 2L + 2(22) = 96
2L + 44 = 96
2L = 52
L = 26cm

• The length is 26cm and width is 22 cm.

Answer:

A. A(n) = 150 • (0.74)^n–1 ; 33.29 cm

Step-by-step explanation:

This is a geometric sequence.

a%5B1%5D=1.5m=150cm, r=0.74

The formula is

a%5Bn%5D=a%5B1%5Dr%5E%28n-1%29

Just substitute a1 = 150cm and r = 0.74

a%5Bn%5D=150%280.74%29%5E%28n-1%29

That's the rule.

For the second part, substitute n = 6

What is the value of g(−3) when g(x)=2x−2 ?
hram777 [196]

To solve a function like this, simply put the numerical value in place of the unknown variable for which you have to find the solution, for instance '-3' in this case.

g(x) = 2x-2

so to find g(-3), we just need to replace the x in the given expression by '-3'. Working is shown below:

g(x) = 2x-2

putting '-3' in place of x

g(-3) = 2(-3) - 2

g(-3) = -6 -2

g(-3) = -8
