For each sequence, find the first 4 terms and the 10th term.<br> a) 3n + 4<br> b) 4n-5

Studentka2010 [4]

Answer:

see explanation

Step-by-step explanation:

To find the first 4 terms substitute n = 1, 2, 3, 4 into the formula, that is

(a)

a₁ = 3(1) + 4 = 3 + 4 = 7

a₂ = 3(2) + 4 = 6 + 4 = 10

a₃ = 3(3) + 4 = 9 + 4 = 13

a₄ = 3(4) + 4 = 12 + 4 = 16

Similarly substitute n = 10 for tenth term

a₁₀ = 3(10) + 4 = 30 + 4 = 34

(b)

a₁ = 4(1) - 5 = 4 - 5 = - 1

a₂ = 4(2) - 5 = 8 - 5 = 3

a₃ = 4(3) - 5 = 12 - 5 = 7

a₄ = 4(4) - 5 = 16 - 5 = 11, and

a₁₀ = 4(10) - 5 = 40 - 5 = 35

I do not know how to do this! Please help me!

$\qquad\qquad\huge\underline{\boxed{\sf Answer}}$

Perimeter of given figure is equal to :

Perimeter of square - side length + quarter Circumference of the circle

that is :

$\qquad \sf \dashrightarrow \:(10 \times 4) - (5 + 5) + \dfrac{2 \pi r}{4}$

$\qquad \sf \dashrightarrow \:40- 10 + \dfrac{3.14 \times 5}{2}$

$\qquad \sf \dashrightarrow \:30+ \dfrac{15.7}{2}$

$\qquad \sf \dashrightarrow \:30 + 7.85$

$\qquad \sf \dashrightarrow \:37.85 \: \: units$

So, the required perimeter is 37.85 units

What’s the volume?<br> someone please help

bazaltina [42]

Answer:

17734.55 inches cubed. If you found this helpful, love the answer! Thank you :D

Step-by-step explanation:

Very simple. We find the area of the circle, A=Pi Radius Square.

So 3.14 (15x15)

A≈706.86

The bottom shape is 706.86x24=16964.64

The top is a cone, meaning its V≈3769.91

So 3769.91+16964.64=17734.55
