Answer:

y^-1 = (x + 4)/5

Step-by-step explanation:

To find the inverse equation of the function y=5x - 4, first we need to switch the x and y:

→ y = 5x - 4

→ x = 5y - 4

Now, solving for 'y':

→ x = 5y - 4

→ x + 4 = 5y

→ y = (x + 4)/5

therefore, the inverse equation is: y^-1 = (x + 4)/5

What is the factored form of the polynomial? z2 − 10z + 25

Crank

Answer:

(z−5)(z−5)

Step-by-step explanation:

Let's factor z2−10z+25

z2−10z+25

The middle number is -10 and the last number is 25.

Factoring means we want something like

(z+_)(z+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -10

Multiply together to get 25

Can you think of the two numbers?

Try -5 and -5:

-5+-5 = -10

-5*-5 = 25

Fill in the blanks in

(z+_)(z+_)

with -5 and -5 to get...

(z-5)(z-5)

A prestigious investment bank designed a new security that pays a quarterly dividend of $3.70 in perpetuity. The first dividend

Andru [333]

Answer:

the price of the security will be $448.485

Step-by-step explanation:

Annual rate of interest = 3.3%

then Interest rate per quarter (r) will be = 0.033/4

= 0.00825

= 0.825%

now it is given that

Cash flows in the first quarter, C1 = $3.70

Then Present value of perpetuity = C1 /r

= $3.70/ 0.825%

= $448.485

Therefore, the price of the security will be $448.485

(out loud) Find the percentages. 15m is what percent of 60m; 3m; 30m; 1.5 km?

N76 [4]

Answer: 15meter is 25% of 60m

15m is 500% of 3m

15m is 50% of 30m

15m is 1% of 1.5km.

Step-by-step explanation:

Given: 15m is what percentage of 60m; 3m; 30m; 1.5km

To find: Find the percentage.

Formula used: 1 kilometer=1000meter.

Explanation:

Let X percentage of 60m =15meter

So, X% of 60m =15m

$\frac{60X}{100}$ = 15m

Multiply both side by 100.

60X = 1500m

On dividing both side by 60

X = 25%

Let X percentage of 3m =15meter

So, X% of 3m =15m

$\frac{3X}{100}$ = 15m

Multiply both side by 100.

3X = 1500m

On dividing both side by 3

X = 500%

Let X percentage of 30m =15meter

So, X% of 30m =15m

$\frac{30X}{100}$ = 15m

Multiply both side by 100.

30X = 1500m

On dividing both side by 30

X = 50%

Let X percentage of 1.5km =15meter

Convert kilometer into meter by above formula (1.5km=1500meter)

So, X% of 1500m =15m

$\frac{1500X}{100}$ = 15m

Multiply both side by 100.

1500X = 1500m

On dividing both side by 1500

X = 1%

Therefore , 15meter is 25% of 60m

15m is 500% of 3m

15m is 50% of 30m

15m is 1% of 1.5km.
