Formula for this is (sqrt(2)^(n-1))*sqrt(5) such that n is the term number
So sqrt(2)^8(sqrt(5))
The answer is (B) 16sqrt(5)

Answer:

16sqrt5

Step-by-step explanation:

Notice that the next term is the previous term multiplied by sqrt2.

So we can take sqrt5 and multiply it by sqrt2, 8 times to get the ninth term.

sqrt2 ^8 = 16.

So 16sqrt5

Find the area of the shaded region.

taurus [48]

Answer:

$426.96 \: {km}^{2}$

Step-by-step explanation:

Area of the shaded region = Area of triangle with base 40 km and height 27 km - Area of circle with radius (12/2) 6 km.

$= \frac{1}{2} \times 40 \times 27 - 3.14 \times {(6)}^{2} \\ \\ = 20 \times 27 - 3.14 \times 36 \\ \\ = 540 - 113.04 \\ \\ = 426.96 \: {km}^{2}$

JUUL Practice & Problem Solving 7.4.PS-10 Question Help Find the area of the polygon in square units. 4 2 e - 8 -6 - 4 - 2 4

V125BC [204]

area formula is

$A=\frac{1}{2}(b1+b2)h$

where:

b1 = small base

b2 = large base

h = height

then solve:

$A=\frac{1}{2}(2+6)3=\frac{1}{2}(8)3=\frac{24}{2}=12$

asnwer: 12 square units

A $4000 deposit in an account after 1 year with an APR of 3.6. How much is the balance after 1 year?

BaLLatris [955]

Hi!
Let's divide 4000 by 1000 to see what .1% would be: $4.
Now we multiply 4 by 36 to get 3.6% of 4000: $ 144
Add 4000 and 144 together:40144.
hope this helps!
