uysha [10]

Answer:

2.86 miles.

Step-by-step explanation:

We have been given that Megan uses a pedometer to find how many steps she takes each school day. she took 32,410 steps over the course of 5 days.

\text{Steps per day}=\frac{32410}{5}

\text{Steps per day}=6482

\text{Inches in 6482 steps}=6482\times 28

\text{Inches in 6482 steps}=181496

1 feet = 12 inches.

\text{Feet in 6482 steps}=\frac{181496}{12}

\text{Feet in 6482 steps}=15124.666666

\text{Miles in 6482 steps}=\frac{15124.666666}{5280}

\text{Miles in 6482 steps}=2.8645

\text{Miles in 6482 steps}\approx 2.86

Therefore, Megan walks 2.86 miles on Monday.

If sin (x-3)° = cos (2x + 6)°, then what is the value of x?
Travka [436]

Answer:

if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.

----------

Note: sin and cos are complementary functions....

sin(x) = cos (90-x)

-------------------

Your Problem:

sin(x-3) = cos(90-(x-3))

Equation:

90-[x-3] = 2x+6

90-x+3 = 2x+6

3x = 93-6

x = 31-2

x = 29

Multiply and simplify. (2x - 1)(6x - 7)
Kryger [21]

Answer:

D) 12x² - 20x + 7

Step-by-step explanation:

Use FOIL when multiplying 2 binomials...

FOIL is Firsts, Outsides, Insides, Lasts.  It's the order in which you multiply the numbers in the binomials...

(2x - 1)(6x - 7)    

Firsts:  (2x)(6x) = 12x²

Outsides:  (2x)(-7) = -14x

Insides:  (-1)(6x) = -6x

Lasts:  (-1)(-7) = 7

Now add them up...

12x² - 14x - 6x + 7

    12x² - 20x + 7
