The range is the difference between the highest and lowest pays.

Highest pay: GS-5 - 2,252

Lowest pay: GS-1 - 1,461

Range = 2252 - 1461 = 791

The answer is D. $791

Find the Y coordinate of the vertex of the PA RK be OLA who’s equation is why equals X2 minus X +2. A is one and three fourths B
shutvik [7]

Answer

A) one and three fourths

Step by step explanation

y = x^2 - x + 2

Here we have to use the formula.

The x coordinate of the vertex = -b/2a

Compare the given equation  y = x^2 - x + 2 with the general form y = ax^2 + bx + c and identify the value of "a" and "b"

Here a = 1 and b = -1

Vertex of x coordinate = -b/2a, now plug in the value of a and b, we get

x = - (-1)/2(1)

x = 1/2

Now we have to find the y-coordinate of vertex.

Now plug in x = 1/2 in the given equation, we get

y = (1/2)^2 - 1/2 + 2

y = 1/4 - 1/2 + 2

y = 1 3/4

That is one and three fourths.

The answer is A) one and three fourths.

Thank you.

Hi:) I need help with part 9(ii) ? Thanks :)!
Goshia [24]

Answer:

see explanation

Step-by-step explanation:

Given

2BD = 7BT , then

2(d - b ) = 7(t - b) ← distribute both sides

2d - 2b = 7t - 7b ( add 7b to both sides )

2d + 5b = 7t, thus

2\left[\begin{array}{ccc}10.5\\10\\\end{array}\right] + 5\left[\begin{array}{ccc}0\\3\\\end{array}\right] = 7t

\left[\begin{array}{ccc}21\\20\\\end{array}\right] + \left[\begin{array}{ccc}0\\15\\\end{array}\right] = 7t

\left[\begin{array}{ccc}21\\35\\\end{array}\right] = 7t , thus

t = \frac{1}{7}\left[\begin{array}{ccc}21\\35\\\end{array}\right] = \left[\begin{array}{ccc}3\\5\\\end{array}\right]

Hence T = (3, 5 )
