Simplify 10/16 to the lowest terms and find an equivalent fraction that has a denominator of 32.
Natalija [7]

Answer:

5/8,  20/32

Step-by-step explanation:

Divide 10/16 by 2 as that is the GCF (greatest common factor) = 5/8

To find an equivalent fraction with a denominator of 32 multiply 10/16 by 2 = 20/32

(8.6x107)-(9.1x10-8)simplify
natima [27]

Answer:

  85,999,999.999 999 909

Step-by-step explanation:

The expression represents the difference of a relatively large number and one that is relatively small. That difference is approximately the value of the large number. The exact value requires 17 digits for its proper expression. Most calculators and spreadsheets cannot display this many digits.

<h3>Standard form</h3>

The numbers in standard form are ...

  86,000,000 = 8.6×10^7

  0.000000091 = 9.1×10^-8

<h3>Difference</h3>

Their difference is ...

  86,000,000 -0.000000091 = 85,999,999.999 999 909

In scientific notation, this is ...

  8.599 999 999 999 990 9×10^7

4d^-3 multiplyed by d^18
Verdich [7]
4*d^(-3)*d^18 = 4*d^(18-3) = 4*d^(15).  The trick here is to combine the exponents.

Another way to write this problem would be:

4*d^18
---------- .  Here d^18 divided by d^3 results in d^15, so again the final 
  d^3         answer is 4*d^15.

A particle moves so that r(t) = ati + b sin atj. Show that the magnitude of the acceleration of the particle is proportional to
ValentinkaMS [17]

Answer:

Step-by-step explanation:

Given

Position of particle is r(t)=at\hat{i}+b\sin (at)\hat{j}

i.e. distance from x axis is b\sin (at)---1

Distance from y axis at

velocity is given by v=\frac{\mathrm{d} r}{\mathrm{d} t}

v=a\hat{i}+ba\cos (at)\hat{j}

Similarly acceleration is given by

a=\frac{\mathrm{d} v}{\mathrm{d} t}

a=0\hat{i}-a^2b\sin (at)\hat{j}

Magnitude of acceleration is =\sqrt{(-a^2b\sin (at))^2}

=a^2b\sin (at)----2

From 1 and 2 we can see that

Magnitude of acceleration is proportional to distance from x axis

a\propto distance\ from\ x-axis
