A1=2 and a8=74 what is the sum

Papessa [141]

Sum of the first 8 terms in an arithmetic sequence is 304.

Given that, $a_{1}=2$ and $a_{8}=74$ .

<h3>What is sum of arithmetic sequence?</h3>

The sum of the arithmetic sequence formula is defined as the formula to calculate the total of all the terms present in an arithmetic sequence.

The sum of the first n terms in an arithmetic sequence is (n/2)⋅(a₁+aₙ).

Now, sum of the first 8 terms in an arithmetic sequence is

$a_{8}=$ (8/2).(2+74)

=4×76

=304

Therefore, sum of the first 8 terms in an arithmetic sequence is 304.

Please help!! Double points! write the ratios for sin X and cos X (Image attached)

Orlov [11]

Answer:

The ratio for sin(X) is $\frac{\sqrt{119} }{12}$

The ratio for cos(X) is $\frac{5}{12}$

Step-by-step explanation:

- The ratio of the sine of a right triangle is:

$sin(\alpha)=\frac{opposite-side}{hypotenuse}$

Since we need the ratio for angle X, $\alpha =X$ . From the picture we can infer that the opposite side of X is $\sqrt{119}$ . The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:
