$6.89

The book is $10. Minus the 35% discount ($10X0.35=$3.50). So the subtotal is $10-$3.50=$6.50.

Tax is 6%. So 0.06X$6.50=$0.39

The total including tax is $6.50+$0.39=$6.89

Bob completed a race in half of an hour. He ran 4 laps. Each lap was ran equally. How much of an hour did bob run on each lap?
Stels [109]

Answer:

Time taken for each lap = 3/8 of an hour

Step-by-step explanation:

Given:

Time taken for 4 laps = 1\frac{1}{2} = 3/2 hours

Find:

Time taken for each lap

Computation:

Time taken for each lap = Time taken / Number of laps

Time taken for each lap = (3/2) / 4

Time taken for each lap = 3/8 of an hour

Rachel Newton scored 26 points in a recent basketball game without making any 3-point shots. She scored 19 times, making several
Readme [11.4K]

Answer:

She made 7  field goals

Step-by-step explanation:

With the data we can make 2 equations

1 x + 2 y= 26

x+y=19  and y=19-x

Where,

x= free throws

y=field goals

Replacing y in the first equation

1 x + 2 (19-x)= 26

1 x + 38-2x= 26

1 x - 2x= 26 - 38

- 1x= -12

x=12

y=19-12

y=7

Find the vertex and axis of symmetry for f(x)=2x^2-1
vfiekz [6]
<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>

<em><u>Solution:</u></em>

<em><u>Given is:</u></em>

f(x) = 2x^2 - 1

We have to find the vertex and axis of symmetry

<em><u>The general equation is given as:</u></em>

f(x) = ax^2 + bx + c

Comparing with given equation,

a = 2

b = 0

c = -1

<em><u>The axis of symmetry is given as:</u></em>

x = \frac{-b}{2a}

x = \frac{0}{2(2)}\\\\x = 0

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1

Thus, y coordinate of the vertex is -1

Therefore, vertex is (0, -1)
