20. Suppose that A is a number with log(A) = 1.352.<br> a. What is the value of log(1000A)?

Anastaziya [24]

Answer:4.352

Step-by-step explanation:

Given

$\log \left ( A\right )=1.352$

we know

$\log \left ( x\right )=y$

Thus $x=10^{y}$

Applying identity we get

$A=\left ( 10\right )^{1.352}$

$A=22.4905$

For $\log \left ( 1000A\right )$

$=\log \left ( 1000\times 22.49\right )$

$=\log \left ( 22490.5461\right )$

$=4.352$

Cos xcos y=1/2(sin(x+y)+ sin(x-y))

garri49 [273]

Taking Rhs

1/2 [sin(x+y)+ sin (x-y)]

using sinA + sin B = 2 cos (A+B)/2 cos( A - B)/2

1/2 [ 2 Cos ( x+y+x-y)/2 . Cos (x+y-x+y)/2]

=Cos 2x/2. Cos 2y/2 = Cos x . Cos y

Hence true

Answer:

8.−2x^2+6x

9.y-1

Step-by-step explanation:

8.(−2x)(x−3)

=(−2x)(x+−3)

=(−2x)(x)+(−2x)(−3)

=−2x^2+6x

9. y^2−y

= y^2−y

=y−1
