Answer:

The value of <em> </em>\frac{14}{8} + \frac{15}{12}  = 3

Step-by-step explanation:

<u><em>Explanation</em></u>

<em>Given       </em>\frac{14}{8} + \frac{15}{12}<em></em>

<em></em>

<em>L.C.M     8 , 12   is  24</em>

<em>          </em>

<em>        </em>\frac{14}{8} + \frac{15}{12} = \frac{14 X 3 + 15 X 2}{24}<em></em>

<em>                   = </em>\frac{42 +30}{24} = \frac{72}{24} = 3<em></em>

<u><em>Final answer</em></u><em>:-</em>

The value of <em> </em>\frac{14}{8} + \frac{15}{12}  = 3

mariarad [96]

Answer:

The rate of change of the function given = 3288

Step-by-step explanation:

Given in the question the equation:

G(t) = 100(1.037)24t

The average rate of change of function is given by this expression:

<h3>f(b) - f(a) / (b - a)</h3><h3 />

cells present at start = when t = 0

a = 0

cells present after an hour = t = 1

b = 1

<h3>Put these values in the formula</h3>

f(1) - f(0) / (1 - 0)

100(1.037)24(1) - 100(1.037)24(0) / 1

3288 - 0 / 1

3288 / 1

3288

Please help me with this problem
My name is Ann [436]

Answer:

6A- 8B = \left[\begin{array}{ccc}56&50&-14\\-126&92&62\\-78&26&2\end{array}\right]

Option A is correct.

Step-by-step explanation:

A=\left[\begin{array}{ccc}-4&-1&-9\\-9&6&9\\-1&-1&3\end{array}\right] \\B=\left[\begin{array}{ccc}-10&-7&-5\\9&-7&-1\\9&-4&2\end{array}\right]

We need to find 6A - 8B

Multiply matrix A with 6 and matrix B with 8 and then subtract 6A - 8B

6A=\left[\begin{array}{ccc}-24&-6&-54\\-54&36&54\\-6&-6&18\end{array}\right] \\8B=\left[\begin{array}{ccc}-80&-56&-40\\72&-56&-8\\72&-32&16\end{array}\right]\\6A - 8B =\left[\begin{array}{ccc}-24-(-80)&-6-(-56)&-54-(-40)\\-54-(72)&36-(-56)&54-(-8)\\-6-(72)&-6-(-32)&18-(16)\end{array}\right] \\6A - 8B =\left[\begin{array}{ccc}-24+80&-6+56&-54+40\\-54-72&36+56&54+8\\-6-72&-6+32&18-16\end{array}\right] \\6A- 8B = \left[\begin{array}{ccc}56&50&-14\\-126&92&62\\-78&26&2\end{array}\right]

So, 6A- 8B = \left[\begin{array}{ccc}56&50&-14\\-126&92&62\\-78&26&2\end{array}\right]

Option A is correct.
