marshall27 [118]

Answer:

$a_{50}=16$

Step-by-step explanation:

Given that,

An airthmetic sequence,

261,256,251

We need to find the 50th term.

We have,

first term, a = 261

common difference = 256-261 = -5

The nth term of the AP is given by :

$a_n=a+(n-1)d\\\\a_{50}=a+49d\\\\a_{50}=261+49(-5)\\\\a_{50}=16$

So, the 50th term of the sequence is 16.

Which number are in order from least to greatest

Mashutka [201]

I’m gonna say that the thrid option is from least to greatest. -2.5, -2.3 -1.5, -1, -0.9. This is because the higher the number is as a negative the more negative it is, making it more less than the others. Hope this helps.

Estimate the area of a triangle with a base of 15.22 km and a height of 13.91 km.

BaLLatris [955]

Given a triangle with a base of 15.22 km and a height of 13.91 km. We can find the area of the triangle using the formula below.

$\text{Area of a triangle = }\frac{1}{2}\times\text{base x height}$ $\begin{gathered} \text{Area of triangle = }\frac{1}{2}\times15.22\times13.91 \\ =0.5\times15.22\times13.91 \\ =105.8551\operatorname{km}^2 \end{gathered}$

Answer: The area of the triangle is

$105.8551\operatorname{km}^2$
