Which statements are true? (look at picture)

Makovka662 [10]

Answer:

D is true, E is true, F is true

Step-by-step explanation:

Hello,

n is an odd number it means that n = 2a+1 where a is integer

$n^2-1=(2a+1)^2-1=4a^2+4a+1-1=4a(a+1)$

this is not an odd number

$n(n-1)=(2a+1)2a$

this is not an odd number

$(n-1)^2=(2a+1-1)^2=4a^2$

this is not an odd number

$n^2+2=(2a+1)^2+2=4a^2+4a+1+2=4a^2+4a+3= 2(2a^2+2a+1)+1$

so this is an odd number

$n(n-2)=(2a+1)(2a-1)=4a^2-1=4a^2-2+1=2(2a^2-1)+1$

so this is an odd number

$(n-2)^2=(2a+1-2)^2=(2a-1)^2=4a^2-4a+1 = 2(2a^2-2a)+1$

this is an odd number

hope this helps

you deposit 300 in an account that pays 5 1/2% annual interest compounded cnyinuously find the balance at the end of 5 years

algol [13]

First find the multiplier: 5.5% + 1 = 1.0505.

Then we do amount x (multiplier) to the power of how many years.

300 x (1.0505)^5

The answer is 383.79696707.

We round this to 2dp, making it £393.80

REMEMBER UNITS!!!

Hope this helps xox :)

WHOEVER ANSWERS CORRECTLY I WILL MARK BRAINLIEST!!

Answer:

Area = 342 $cm^2$ , Perimeter = 22.79 cm

Step-by-step explanation:

First, divide the shape into 3:

An arc, a square, and a triangle.

Dimensions of shapes:

Arc:

Degree = 40°

Arms = 4 cm

Square:

All sides are 4 cm

Triangle:

base = 3 cm

height = 4 cm

hypotenuse = 5 cm

To get perimeter:

Arc length = $\frac{40}{360} * (2*\pi * (4))$ (4 is the arm length ) = 2.7925 cm

Arc arm = 4 cm

Square sides (only two are outside) = 2 * 4 = 8 cm

Triangle (only hypotenuse and base are outside) = 5 + 3 = 8 cm

So total perimeter is 2.7925 + 4 + 8 + 8 = 22.79cm

To get area:

Arc area (the pizza shape) = $\frac{40}{2\pi } * \pi * (4)^{2}$ (4 is the arm length) = 320 $cm^{2}$

Square area = side * side = 4 * 4 = 16 $cm^{2}$

Triangle = (1/2) * base* height = (1/2) * 3 * 4 = 6 $cm^{2}$

So total area is 320 + 16 + 6 = 342 $cm^2$
