Answer:

B. a (n) = -3n + 13

Step-by-step explanation:

Given arithmetic sequence is: 10, 7, 4, 1, -2, ...

Here a = 10, d = 7 - 10 = - 3

$a_n = a + (n - 1)d \\ \\ a_n = 10+ (n - 1)( - 3) \\ \\ a_n = 10 - 3n + 3 \\ \\ \purple{ \bold{a_n = - 3n +1 3 }}\\ \\$

If f(x) = -x + 5 and g(x) = 3x + 2, Find f(2)*g(2).

Romashka [77]

Answer:

Step-by-step explanation:

To find f(#) or g(#), plug the number into each x of the equation.

f(x) = -x + 5

f(2) = -(2) + 5

Simplify the parentheses by multiplying.

f(2) = -2 + 5

Add.

f(2) = 3

g(x) = 3x + 2

g(2) = 3(2) + 2

Simplify the parentheses by multiplying.

g(2) = 6 + 2

Add.

g(2) = 8

Now they are asking you to multiply

f(2) • g(2)

3 • 8

= 24

Hope this helps!

Geometry questionnn!

Musya8 [376]

Answer:

88 units

Step-by-step explanation:

$In\: \triangle OBR \:\&\: \triangle OWN$

BR || WN (Given)

Therefore,

$\angle OBR \cong \angle OWN$ (Alternate angles)

$\angle BOR \cong \angle WON$ (Vertical angles)

$\therefore \triangle OBR \sim \triangle OWN$ (AA postulate)

$\therefore \frac{OR}{ON} =\frac{BR}{WN}$ (csst)

$\therefore \frac{OR}{56} =\frac{24}{42}$

$\therefore \frac{OR}{56} =\frac{4}{7}$

$\therefore OR =\frac{4\times 56}{7}$

$\therefore OR ={4\times 8}$

$\therefore OR =32$

RN = OR + ON

RN = 32 + 56

RN = 88 units
