Solve the equation log^7b>2

ahrayia [7]

Answer:

b > 12.71

Step-by-step explanation:

Here in this question we have to solve the inequality equation given for b (An unknown variable}

Now, the equation is $(\log b)^{7} > 2$

⇒ $\log b > 2^{\frac{1}{7} }$

We are taking the base of the log here is 10.

So, $10^{(\log b)} > 10^{2^{\frac{1}{7} } }$ {Since $10^{\log x} =x$ and $e^{\ln x} = x$ }

⇒ b > 12.71 (Approximate) (Answer)

Erica (35 kg ) and Danny (44 kg ) are bouncing on a trampoline. Just as Erica reaches the high point of her bounce, Danny is mov

Tema [17]

Answer:

v= 2.66 m/sec

Step-by-step explanation:

supposing we have to find their speed just as he grabs her.

Applying law of conservation of Energy

That is

p_i= p_f

Initial momentum = p_i = 35×0+ 44×4.9= 210.6 kg.m/sec.

final momentum p_f= (35+44)v

let the final velocity of combined body be v

therefore,

79v= 210.6

v= 2.66 m/sec.

What is the value of (5.3 times 10 Superscript 4 Baseline) (4.2 times 10 Superscript 3) in scientific notation?

katovenus [111]

Answer:

$2.226X 10^8$

Step-by-step explanation:

We are to determine the value of $(5.3 X 10^4) (4.2 X 10 ^ 3)$ in scientific notation.

Given:

$(5.3 X 10^4) (4.2 X 10 ^ 3)$

STEP 1: Remove the brackets.

$(5.3 X 10^4) (4.2 X 10 ^ 3)=5.3 X 10^4X4.2 X 10 ^ 3$

STEP 2: Separate the numbers and index of 10.

$=5.3 X4.2X 10^4 X 10 ^ 3$

STEP 3: Multiply the Numbers and Index of 10

$=22.26X 10^{4+3}$

STEP 4: Simplify and write in Scientific notation

$22.26=2.226X10\\Therefore:\\22.26X 10^{4+3}=2.226X10X 10^{4+3}=2.226X10X 10^7=2.226X 10^8$

Thus:

$(5.3 X 10^4) (4.2 X 10 ^ 3)=2.226X 10^8$ in scientific notation
