Answer:

f(x)=2(x+7)^2-103

Step-by-step explanation:

f(x) = 2x^2+28x - 5

To find out vertex apply the formula x=-b/2a

The value of a=2 and b=28

x=\frac{-b}{2a} =\frac{-28}{4} =-7

Now plug in x=-7 in f(x) equation and find out f(-7)

f(-7) = 2(-7)^2+28(-7)- 5=-103

Vertex is (-7,-103)

Now use vertex formula

f(x)=a(x-h)^2+k

a=2, h=-7, k=-103

Plug in all the values in the vertex form equation

f(x)=2(x+7)^2-103

Answer:

Total number of tablets needs to discharge = 240 tables

Step-by-step explanation:

Given:

Number of days tablet need = 30 days

Number of times per days need = 4 times

Number of tablet per time = 2 tablet

Find:

Total number of tablets needs to discharge = ?

Computation:

⇒ Total number of tablets needs to discharge = Number of days tablet need × Number of times per days need × Number of tablet per time

⇒ Total number of tablets needs to discharge = 30 × 4 × 2

⇒ Total number of tablets needs to discharge = 240 tables

Use the simple interest formula to find the ending balance 5000 at 5% for 3.5 years
Evgesh-ka [11]

Answer:

Given:  Principal(P) = $ 5000 , T = 3.5 years and R = 5%.

Using the formula of Simple Interest (I) given by;

I = \frac{P\times R \times T}{100} .......[1] , where P is the Principal amount of money to be invested, R be the rate of interest and T be the time.

Substitute the given values of P ,  R and T in [1] we have;

I = \frac{P \times R \times T}{100} = \frac{5000\times 5 \times 3.5}{100}

I = 50 \times 5 \times 3.5 = 250 \times 3.5

Simplify:

I = \$ 175

An Ending balance is calculated by subtracting cash outflows, interest paid for financing and principal paid on financing.

Ending Balance = $ 5000 + $ 175 = $ 5,175.

Therefore, the ending balance is $ 5,175
