Answer:

see explanation

Step-by-step explanation:

(a)

Following the direction of the arrow, the vector is from tail to nose, 3 units left in the x- direction (- 3) and 2 units up in the y- direction ( + 2), thus

d = \left[\begin{array}{ccc}-3\\2\\\end{array}\right]

(b)

Add the corresponding components in the 2 vectors

h + k = \left[\begin{array}{ccc}4-2\\-3-1\\\end{array}\right] = \left[\begin{array}{ccc}2\\-4\\\end{array}\right]

If I = prt; p = 350, r = 6%, I = 42, then t = 2 A. True B. False
Liono4ka [1.6K]

t = 2 → A true

given I = PRT

to find T , divide both sides by PR

note that R = 6% = \frac{6}{100} = 0.06

T = \frac{I}{PR} = 42/( 350 × 0.06 ) = 2

If using the method of completing the square to solve the quadratic equation
lubasha [3.4K]

Answer:

31.25

Step-by-step explanation:

The general form of a complete square would be (x + a)^2 + b

Given an equation of X^2 + 15X + 25 = 0,

the idea is to reduce it into the form if (X + C)^2

which can be expanded into X^2 + 2XC + C^2

In this case 15 will be our 2C So our c will be 7.5.

Substituting in these numbers,

We have X^2 + 15X + (7.5)^2 = 0

However our original equation has 25 for its C^2, thus

we need to add 31.25 in order to get (7.5)^2

<u>FYI</u>

The final completed form will be (X + 7.5)^2 - 31.25
