Answer:

a₇ = 16992.84

Step-by-step explanation:

Given that,

a₁ = 11, r = 3.4 and n = 7

The geometric sequence is given by :

$a_n=a_1\cdot r^{n-1}$

Put all the values,

$a_7=11\times (3.4)^{7-1}\\\\=11\times (3.4)^6\\\\=16992.84$

So, the seventh term is equal to 16992.84.

What would be the equation -2x+y+3=0 in y=mx+b form?

ololo11 [35]

Answer:

The answer is y = 2x - 3.

Step-by-step explanation:

Move 2x to the right side of the equation by adding it to both sides:

-2x + y + 3 = 0

+ 2x + 2x

y + 3 = 2x

Then, move 3 to the right side of the equation by subtracting it form both sides:

y + 3 = 2x

- 3 - 3

y = 2x - 3

Someone pls help im so close

Sliva [168]

Answer: A) 126.6

Step-by-step explanation:

Since we know ∠B = 85° and ∠C = 53°, we can use the Triangle Sum Theorem (angles of a triangle = 180°) to calculate ∠A.

∠A + ∠B + ∠C = 180

∠A + 85 + 53 = 180

∠A + 138 = 180

∠A = 42

Now we have:

A = 42 B = 85 C = 53

a = 85 b = ??? c = ???

We have all of the information for ∠A and side a so we can use the Law of Sines to find b (AC).

$\dfrac{\sin 42}{85}=\dfrac{\sin 85}{b}\\\\\\b(\sin 42)=85(\sin 85)\\\\\\b=\dfrac{85\sin 85}{\sin 42}\\\\\\b=\large\boxed{126.547}$
