Given: KLMN is a trapezoid, KL=MN,
sp2606 [1]
<h3>Answer:</h3>

∠K = ∠N = 60°

∠L = ∠M = 120°

<h3>Step-by-step explanation:</h3>

In the attached, we have renamed F to G so Brainly will let us talk about it more easily. We have also added altitude MX.

AG is also a midsegment of ΔKLM, so LM = 2×AG = 4. Then ...

... NX = AB - LM = 7 -4 = 3

and we have right ΔMXN with hypotenuse 6 and leg 3. This is recognizable as a 30°-60°-90° triangle, with the 60° angle at N.

The angle at M is supplementary to that at N (because LM ║ KN), so measures 120°

The trapezoid is isosceles, so angles K and L have the same measures as angles N and M.

Given the Function:
sergey [27]
F(x)=-2e^x
x=3
f(3)=-2e^3
pemdas so exponents first
e^3
e=2.718281828454590
cube that
20.0855

now we have
-2 times 20.0855=-40.1711

answer should be -40.1711
(I see what you did wrong, if -6=-2 times e^3, divide -2, 3=e^3, maybe you just put -2 times 3 by mistake)

ANSWER

The explicit formula is :

a_n = 8+ 3(n - 1)

EXPLANATION

The given sequence is

8,11,14,17,20,23,26,...

The first term is

a_1=8

The common difference is

d=11-8

d=3

The explicit formula is given by:

a_n = a_1 + d(n - 1)

We substitute the values to get,

a_n = 8+ 3(n - 1)
