Answer:8.00347847

Step-by-step explanation:

y= 8.00347847 i think, we use SIN, because we are given the opposite and hypotonuse. sin(61)=7/y which equals 8.00347847. Don't quote me on it though i havent done geometry in a while

Find the explicit formula for the general nth term of the arithmetic sequence described below. Simplify the formula and reduce a

NemiM [27]

Answer:

an = 4/3n - 13/3.

Step-by-step explanation:

The first term is a1,

a24 = a1 + 23d

83/3 = a1 + 4/3* 23

a1 = 83/3 - 92/3

a1 = -9/3 = -3.

So the nth term an = -3 + 4/3(n - 1)

an = -3 + 4/3 n - 4/3

an = 4/3n - 13/3

(7t-2)-(-3+1)=-3(1-3t) how do you do this?

Sergeu [11.5K]

<h2>Greetings!</h2>

Answer:

t = $\frac{3}{2}$

Step-by-step explanation:

First, you need to complete the -3 + 1 and then expand the brackets

-3 + 1 = -2

7t -2 - (-2) = -3(1 - 3t)

Now expant the -3(1 - 3t) bracket

-3 * 1 = -3

-3 * -3t = 9t

7t - 2 - -2 = 9t - 3

The two negatives turn positive:

7t - 2 + 2 = 9t - 3

7t = 9t - 3

Move the -3 over to the oposite side, and also move the +7t over to the +9t, making it a negative:

3 = 9t - 7t

3 = 2t

Divide both sides by 2:

t = $\frac{3}{2}$

So the value of t is $\frac{3}{2}$

Solve for x under the assumption that x > 0. Enter your answer in interval notation using grouping symbols.

Delicious77 [7]

<span>Starting with x−24/x<10 multiply everything by x. x^2-24<10x Subtract 10x from both sides. x^2-10x-24 < 0 Factor. (x-12)(x+2) < 0 (x+2) is always positive since x > 0, but (x-12) is negative when x is a value between 0 and 12. This negative value for (x-12) satisfies that the left side is less than 0. Thus the solution set for x is (0,12).</span>
