5. Suppose you invested PHP 25,000 at a simple interest at a rate of 2.5%, how much will be your investment after
10 years? a. PHP 43,750.00
C.PHP 45,730.00
b. PHP 31,250.00
d. PHP 47,350

Answers

Answer:

b. PHP 31,250.00

Step-by-step explanation:

Simple interest = principal × rate × time

Principal = PHP 25,000

Rate = 2.5%

Time = 10 years

Simple interest = principal × rate × time

= PHP 25,000 × 2.5% × 10

= 25,000 × 0.025 × 10

= 6,250

Simple interest = PHP 6,250

Investment after 10 years = principal + simple interest

= PHP 25,000 + PHP 6,250

= PHP 31,250

Investment after 10 years = PHP 31,250

8.6 x10^-9 in standard form

Answers

-9 in power means that the value is in fractional and the 10 base is multipied 9 times and put it on denominator.

8.6 = 86 x 10^-1

Let's multiply :

86 x 10^-1 x 10^-9

= 86 x 10^-10

= 86/10000000000

=0,0000000086

Note : if you don't know about how 10^-1 x 10^-9 returns 10^-10, it's because of exponential rules. If the base are same wuth each other, then just do the addition operation in the exponent like this :

10^(-1+(-9))

= 10^(-1-9)

=10^-10

Manny needs to solve the equation x2 – 8x – 24 = 0 by completing the square. Which pair of steps is the most efficient way to begin?

Answers

Answer:

B

Step-by-step explanation:

So for some reason the person didn't put the equations... I had the same question so here they are.

A.x^2 – 8x = 24

x2 – 8x + 4 = 24 + 4

B.x^2 – 8x = 24

x2 – 8x + 16 = 24 + 16

C.x^2 – 8x = 24

x2 – 8x + 64 = 24 + 64

D.x^2 – 8x = 24

x2 – 8x + 144 = 24 + 144

The quadratic equation can be solved by completing square method. The steps to solve the given equation are explained in detail.

What is a quadratic equation?

The general form of a quadratic equation is given as ax^2 + bx + c = 0.

Here, a ≠ 0 and b and c are integers.

The degree of a quadratic equation is 2.

The given equation is,

x^2 - 8x -24 = 0

To solve this equation by completing square method, it has to be transformed into the form of (a + b)^2.

The steps for this method are given as follows,

(i) Find the coefficient of x^2. The square root of the this coefficient is the value of a.  

(ii) Find the term containing non-square part. In the given case it is -8x.

(iii) Compare the coefficient of this term with 2ab. it gives,

2ab = -8

=> 2 × 1 × b = -8

=> b = -4

(iv) Write the equation in the form of a^2 + 2ab + b^2 leaving the remaining term as it is. For the given equation it can be written as,

x^2 - 8x + 4^2 - 40 = 0

=> x^2 - 8x + 4^2 = 40

(v) Now, write the equation in terms of (a +b)^2 and get the solution. In this case it is written as,

(x - 4)^2 = 40

=> x - 4 = ±√40

=> x = 4 ±√40
