Answer:

<u>-335670</u>

Step-by-step explanation:

<u>Given</u> :

a₁ = 2
$a_{i} = a_{i-1}-3$

<u>Solving</u> :

Sum of an arithmetic sequence is given by
S₃₃₅ = 335/2 x 2(2) + (335 - 1)(-3)
S₃₃₅ = 335/2 x -4008
S₃₃₅ = 335 x -2004
S₃₃₅ = <u>-335670</u>

here is a list of ingredients for making 12 rock cakes nihay wants to make 42 cakes does she have enough sugar to make 42rock ca

Nostrana [21]

Step-by-step explanation:

So we know that for 12 rock cakes we need 225g flour and 75g sugar to get 42 rock cakes we need to multiply the number of ingredients by 3.5 (42/12 =3.5)

This gets us 787.5 g flour and 262.5 g sugar.

Show work:

$42 \div 12 = 3.5$

$225 \times 3.5 = 787.5$

$75 \times 3.5 = 262.5$

$787.5 < 800$

$262.5 < 300$

Nishat has enough flour and sugar to make 42 rock cakes.

NEED HELP IN MATH .THANKS

stira [4]

It's simple. as long as it's a 10 you just put in however many 0 it has as the root to a 1. or just multiply it however many times.
10x10x10 = 1000
so 10^3 = 1000
then you finish
4.23 x 1000 = 4230

NEED HELP ASAP !! WILL MARK BRAINLEAST<br> SHOW WORK TOO !!!

irinina [24]

Step-by-step explanation:

$(1 + \cos(x) )(1 - \cos(x) )$

$1 - \cos {}^{2} (x)$

$= \sin {}^{2} (x)$

b.

$\frac{1}{ \cot {}^{2} (x) } - \frac{1}{ \cos {}^{2} (x) }$

$\frac{1}{ \frac{ \cos {}^{2} (x) }{ \sin { }^{2} (x) } } - \frac{1}{ \cos {}^{2} (x) }$

$\frac{1}{ \cot {}^{2} (x) } - \frac{ \csc {}^{2} (x) {} }{ \cot {}^{2} (x) }$

$\frac{ - \cot {}^{2} (x) }{ \cot {}^{2} (x) }$

$- 1$

c.

$\sec {}^{2} ( \frac{\pi}{2} - x ) )( \sin {}^{2} (x) - \sin {}^{4} (x))$

$( \csc {}^{2} (x) )( \sin {}^{2} (x) - \sin {}^{4} (x )$

$\csc {}^{2} (x) ( \frac{1}{ \csc {}^{2} (x) } - \frac{1}{ \csc {}^{4} (x) } )$

$1 - \frac{1}{ \csc {}^{2} (x) }$

$1 - \sin {}^{2} (x)$

$\cos {}^{2} (x)$
