Write the product using exponents.

Vilka [71]

The product of the expression (-5)*(-5)*(-5)*(-5)*y*y*y*y is $(-5y)^{4}$

<h3>What is Algebra?</h3>

Algebra is a branch of mathematics that deals with symbols or variables and uses arithmetic operations (+, –, ×, ÷) to find the unknown quantities represented by these variables.

Given expression :

(-5)*(-5)*(-5)*(-5)*y*y*y*y

= $(-5)^{4} *y^{4}$

= $(-5y)^{4}$

Hence, (-5)*(-5)*(-5)*(-5)*y*y*y*y = $(-5y)^{4}$

Given the 2 points (3,1) and (4,6) what is the slope of the line?

zmey [24]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 3 &,& 1~) 
% (c,d)
&&(~ 4 &,& 6~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{6-1}{4-3}\implies \cfrac{5}{1}\implies 5$

How do you write a function of t that represents the situation(sales $10,000 increase by 65% each year)?

Shkiper50 [21]

Answer:

s(t) = 10000·1.65^t

Step-by-step explanation:

The general form of an exponential model is ...

f(t) = (initial value) × (1 +(fractional change))^t

where the fractional change can be positive or negative and t is the number of time units. Each time unit will correspond to the period required for the fractional change.*

For your problem, you have (initial value) = 10,000 and (fractional change) = 65% = 0.65 with time units of 1 year. Your function for sales (s) will then be ...

s(t) = 10000·1.65^t

_____

* The business regarding time units has to do with problems where you get a description like "increased 30% in 4 hours." Then, if t is in hours, the multiplier of the initial value looks like 1.30^(t/4).

Geometry- Solve the portion. Question#4<br>

kotykmax [81]

Answer:

$d=18$

Step-by-step explanation:

<h3>First let's write our equation</h3><h3 /><h3> $\frac{6}{d-6} =\frac{4}{8}$ </h3><h3 /><h3>Reduce</h3>

<em>Definition - </em><em>reduction refers to the rewriting of an expression into a simpler form</em>

<h3 />

We can reduce $\frac{4}{8}$ to $\frac{1}{2}$

Our equation is now $\frac{6}{d-6} =\frac{1}{2}$

Now we can cross multiply

<em>Definition - </em><em>given an equation between two fractions or rational expressions, one can cross-multiply to simplify the equation or determine the value of a variable.</em>

$d-6=12$
