The answer would be 1,235,520. To find this you would have to multiply the first six terms following 13.
13!= 13 x 12 x 11 x 10 x 9 x 8

If it wasn't specifically asking for only 6 terms, every number from 13 to 1 would be multiplied.

HELP PLEASE!!!!!!!!!!!!
Bogdan [553]

Answer:

See the explanation.

Step-by-step explanation:

We are given the function f(x) = x² + 2x - 5

Zeros :

If f(x) = 0 i.e. x² + 2x - 5 = 0

The left hand side can not be factorized. Hence, use Sridhar Acharya formula and  

x= \frac{-2+\sqrt{2^{2}-4\times(-5)\times1 } }{2} and  

x= \frac{-2-\sqrt{2^{2}-4\times(-5)\times1 } }{2}

⇒ x = -3.45 and 1.45

Y- intercept :

Putting x = 0, we get, f(x) = - 5, Hence, y-intercept is -5.

Maximum point :

Not defined

Minimum point:  

The equation can be expressed as (x + 1)² = (y + 5)

This is an equation of parabola having the vertex at (-1,-5) and axis parallel to + y-axis

Therefore, the minimum point is (-1,-5)

Domain :  

x can be any real number

Range:  

f(x) ≥ - 6

Interval of increase:

Since this is a parabola having the vertex at (-1,-5) and axis parallel to + y-axis.

Therefore, interval of increase is +∞ > x > -1

Interval of decrease:

-∞ < x < -1

End behavior :  

f(x) = x^{2} +2x-5 =x^{2}  (1+\frac{2}{x} -\frac{5}{x^{2} } )

So, as x tends to +∞ , then f(x) tends to +∞

And as x tends to -∞, then f(x) tends to +∞. (Answer)

The diagram below shows an Isosceles triangle. Label the base angles and the vertex
Anna007 [38]

The  measure of each base angle is 34 degrees and the measure of the vertex angle is 112 degrees

Find the diagram attached.

The base of the isosceles triangle is "b".

Since the base angles are equal, hence the sum of the interior angle is expressed as:

b + b + 112  = 180

2b + 112  = 180

2b = 180 - 112

2b = 68

b = 68/2

b = 34 degrees

Hence the  measure of each base angle is 34 degrees and the measure of the vertex angle is 112 degrees

<u>Work hours Monday till Friday:</u>

  • 3.5 + 5 + 2.5 + 4 + 2 = 18 hours

<u>Payment for 5 days:</u>

  • 15*$8 + (18 - 15)*$10 = $150

<u>Payment for Saturday:</u>

  • 5*2*$8 = $80

<u>Total payment:</u>

  • $150 + $80 = $230
