Answer:

-1

Step-by-step explanation:

if x is the solution, substitute the value of x in that equation

x -3 = 0

so substitute 3 as x

6(3) - 19 = 3(3) - 10

18 -19 = 9 - 10

-1 = -1

Answer:

c) The growth factor per days is 1.08

e) The growth factor per hour is 1.08^{1/24}

Step-by-step explanation:

Given the following data;

P(d) = 10 * 1.08^{d} in thousands.

a. To find the number of insects on day 1;

Day, d = 1

$P(d) = 10 * 1.08^{d}$ ......equation 1

Substituting into the formula, we have;

$P(1) = 10 * 1.08^{1}$

$P(1) = 10 * 1.08$

$P(1) = 10.08$

Therefore, option (a) and (b) are incorrect.

c. To find the growth factor per day;

An exponential function is given by the formula;

$y = mg^{x}$ .....equation 2

Where;

g is the growth factor of a population.

Comparing eqn 2 with eqn 1;

g = 1.08

Therefore, option (c) is correct.

e. To find growth factor per hour;

From equation 1 above;

$P(1) = 10 * 1.08^{\frac {1}{2}}$

Therefore, option e is correct.

What is the greatest common factor of 35b^2,15b^3 and 5b?

xz_007 [3.2K]

ANSWER

The greatest common factor is 5b.

EXPLANATION

The first expression can be rewritten as

$35 {b}^{2} = 5 \times 7 \times {b}^{2}$

The second expression is rewritten as

$15 {b}^{3} = 3 \times 5 {b}^{3}$

The third expression is

$5b = 5 \times b$

The greatest common factor is the product of the least powers of the common factors.

$GCF=5 \times b = 5b$
