the cost of a telephone call 75 cents plus 25 cents times the number of minutes. write an algebraic expression that models the c

Mrrafil [7]

Since the cost of the telephone cost is 25 cents per minute, and by using the variable you provided, "t", the equation thus far is 25t=cost, or 25 multiplied by "t".

Since the telephone also charges 75 cents at the start, we just have to add it into our equation, making 75+25t=cost of telephone call in cents.

answer: 75+25t=cost of telephone call in cents

A whale descends 382.5 feet in 45 seconds. Write an expression that can be used to find the average elevation change of the whal

NNADVOKAT [17]

Answer:

Part a) The expression is $y=-8.5x$

Part b) -51 feet

Step-by-step explanation:

<u><em>The complete question is</em></u>

A whale descends 382.5 feet in 45 seconds.

The whale's elevation changes at a constant rate.

Part a) Write an expression that can be used to find the average elevation change of the whale during its descent in feet per second

Part b) What is the elevation change of the whale after 6 seconds?

Part a)

we know that

Find out the unit rate

To find out the unit rate divide the total elevation by the total time

Remember that

The sea level represent the level zero

If a whale descends, then the elevation is negative (below the sea level)

$\frac{-382.5}{45}\ \frac{ft}{sec}=-8.5\ \frac{ft}{sec}$

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form

$y/x=k$ or $y=kx$

Let

x ----> the time in seconds

y ----> the elevation in feet

In this problem we have a proportional relationship, because the line passes through the origin (For x=0, y=0)

$y=kx$

The value of the constant of proportionality k is equal to the unit rate or slope of the linear equation

$k=-8.5\ \frac{ft}{sec}$

substitute

$y=-8.5x$

Part b) For x=6 sec

substitute in the linear equation

$y=-8.5(6)$

$y=-51\ ft$

What is the prime factor of 32

ipn [44]

We factor out primes from 32 to find it's prime factorization.

32=2*16=2*2*8=2*2*2*4=2*2*2*2*2. 2 is a prime number, so this cannot be reduced further. Since we have five twos and no other primes, the factorization is 2^5, and the only prime factor is 2.
