Answer:
= - 1.3n - 2.4
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference, thus
= - 3.7 - 1.3(n - 1) = - 3.7 - 1.3n + 1.3 = - 1.3n - 2.4
Answer:
114
Step-by-step explanation:
so lets call shelf 1 x
shelf 2 is twice size + 18 of shelf 1 so it is 2(x)+18
shelf 3 is 12 less than shelf 1 so x-12
shelf 4 is four more so x+4
Add them all together and it should be 5x+10= 2.5 m or 250 cm
Solve for x using cm
then plug into shelf 2 equation
Based on the information given, it has been calculated that they value of x will be 0.9646.

Solving triangles</h3>
Based on the information given, it should be noted that the sine formula will be used.
Therefore, the equation to solve the question will be:
Sin 16° = x/3.5
x = Sin 16° × 3.5
x = 0.2756 × 3.5
x = 0.9646

Step-by-step explanation:
180 -angled triangle,
180-56 = 124
124/2 = 62 (each corner of the right triangle)
then find the corner below
the rectangle has right angles on the right side
x = 90-62
= 28
