Answer:

C

Step-by-step explanation:

The general form of a polynomial expression is

a_{n}x^{n} + a_{n-1}x^{n-1} + a_{n-2}x^{n-2} + ............ + a₁x^{1} + a₀

For the given polynomial the x^{n} term is - x^{13} , that is n = 13 , thus

n - 7 = 6 , that is the x^{6} term

with a_{n-7} being its coefficient

Since there is no x^{6} term, then its coefficient is zero, that is

a_{n-7} = 0 → C

Evaluate the following expression:<br> -X- 6x + 10 when x = 5
BigorU [14]

Answer:

-25

Step-by-step explanation:

Evaluate -x - 6 x + 10 where x = 5:

-x - 6 x + 10 = -5 - 6×5 + 10

-6×5 = -30:

-5 + -30 + 10

-5 - 30 + 10 = 10 - (5 + 30):

10 - (5 + 30)

5 + 30 = 35:

10 - 35

10 - 35 = -(35 - 10):

-(35 - 10)

Work out length of BC
Neporo4naja [7]

Answer:

assume 13 = z \\ 8 =x  \\ bc = y

by phytagorean theorem

{y}^{2}  +  {x}^{2}  = z^{2}

so

bc = y =  \sqrt{ {z}^{2}  -  {x}^{2} } =  \sqrt{169 - 64}   =  \sqrt{105}

Amanda and jamie are standing 25 feet apart and spot a bird in the sky between them the angle of elevation from Amanda is 25 fee
finlep [7]

Answer:

25.2294 feet

Step-by-step explanation:

We can solve this question drawing a triangle using the values given and then using the law of sines. (See image attached to know how to draw the triangle and use the values).

First we need to find the third angle of the triangle, that is, the angle in the vertix where the bird is:

y + 55 + 63 = 180

y = 62°

The relation between the angles and the distances are:

25 / sin(y) = x / sin(63)

25 / 0.8829 = x / 0.8910

x = 25 * 0.8910 / 0.8829 = 25.2294 feet
