Answer:

n = c/z

Step-by-step explanation:

c = zn + z

c/z = zn/z + z/z (Divide all terms by z)

c/z = n + z/z (Simplify)

c/z = n (Simplify further/answer)

Hope this helps :)

How many days would it take a construction loan of $548,048 to earn$50,000 exact interest at 9% interest rate?

sesenic [268]

I guess you mean simple interest
I = PRT/100

50000 = 548048 * 9 * t / 100

t = 50,000 * 100
------------------- = 1.013699 years
548048* 9

multiply this by 365 gives 370 days

Irene wants to list the factors for 88. She

Paladinen [302]

Almost; she's just missing 1, since 1*88 = 88.

<1 and <2 form a linear pair. The measure of <2 is six more than twice the measure of <1. Find the measure of <2

MrMuchimi

Answer:

122 Degrees

Step-by-step explanation:

Since we are given that angle 1 and 2 make a linear pair:

angle 1 + angle 2 = 180 degrees ----------------------------(1)

We have also been told that angle 2 is 6 more than twice the measure of angle 1

Which means: angle 2 = (2*angle1) + 6 -------------------(2)

From putting the value of angle 2 in (1) from (2)

angle 1 + 2*angle 1 + 6 = 180

3*angle 1 = 174

angle 1 = 58 degrees -----------------------(3)

From (1) and (3):

angle 2 + 58 = 180

angle 2 = 122 degrees

Therefore, the measure of angle 2 is 122 degrees

-/2 points

Answer:

Part 1) The domain of the quadratic function is the interval (-∞,∞)

Part 2) The range is the interval (-∞,1]

Step-by-step explanation:

we have

$f(x)=-x^2+14x-48$

This is a quadratic equation (vertical parabola) open downward (the leading coefficient is negative)

step 1

Find the domain

The domain of a function is the set of all possible values of x

The domain of the quadratic function is the interval

(-∞,∞)

All real numbers

step 2

Find the range

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

we have a vertical parabola open downward

The vertex is a maximum

Let

(h,k) the vertex of the parabola

The range is the interval

(-∞,k]

Find the vertex

$f(x)=-x^2+14x-48$

Factor -1 the leading coefficient

$f(x)=-(x^2-14x)-48$

Complete the square

$f(x)=-(x^2-14x+49)-48+49$

$f(x)=-(x^2-14x+49)+1$

Rewrite as perfect squares

$f(x)=-(x-7)^2+1$

The vertex is the point (7,1)

therefore

The range is the interval

(-∞,1]
