Simplify 4n5 + 3.5n5 + (-2.1n5).<br><br> 4.4 n5<br> 5.4 n5<br> 20 n5<br> 6.4 n5
ella [17]

Answer:

4 {n}^{5}  + 3.5 {n}^{5}  + ( - 2.1 {n}^{5} )

first create a bracket:

= ( {4n}^{5}  + 3.5 {n}^{5} ) + ( - 2.1 {n}^{5} )

then solve the first bracket:

=  {7.5 {n}^{5} } + ( - 2.1 {n}^{5} )

then open the remaining bracket:

=  {7.5n}^{5}  -  {2.1n}^{5}

carryout the subtraction operation:

= (7.5 - 2.1) {n}^{5}  \\ { \boxed{ =  {5.4n}^{5} }}

Population Growth The population of a town of 5000
Nesterboy [21]

Answer:

a) A=5000{(1.03)}^{t}

b) 5464 inhabitants.

Step-by-step explanation:

The formula used for compound interest becomes very helpful in this case.

A=P{(1+r)}^{t}\\\\When:\\A = Final Value\\P = Initial Value\\r = Rate of Change (Decimal)\\t = Time (Years)

Knowing this, we can easily calculate the value for any year, counting from the original 5000.

From this formula, we can derive a specific one that will serve for any value of <em>t</em>.

a)

A=5000{(1+0.03)}^{t}\\A=5000{(1.03)}^{t}

b) Apply the formula:

A=5000{(1.03)}^{3}\\A=5000(1.092727)\\A=5463.635=5464

The town will have 5464 inhabitants.

The straight line 3y = 5x + h - 6 intersect the x-axis at 4k, where h and k are constants. explain h in terms of k
inn [45]

When a function intersects with the x-axis, it's y value must be 0. That means when the straight line intersects with the axis, it's at the point (4k,0), so plugging those numbers into our original equation yields:

0=20k+h-6 \implies\\ 6=20k+h \implies \\ 6-20k=h
