Insert the indicated number of arithmetic means between the given first and last

cupoosta [38]

Simplify 12x12x to x2x2
x2−34y=−2x2−34y=−2
2 Simplify 34y34y to 3y43y4
x2−3y4=−2x2−3y4=−2
3 Subtract x2x2 from both sides
−3y4=−2−x2−3y4=−2−x2
4 Multiply both sides by 44
−3y=(−2−x2)×4−3y=(−2−x2)×4
5 Regroup terms
−3y=4(−2−x2)−3y=4(−2−x2)
6 Divide both sides by −3−3
y=4(−2−x2)−3y=4(−2−x2)−3
7 Simplify 4(−2−x2)−34(−2−x2)−3 to −4(−2−x2)3−4(−2−x2)3
y=−4(−2−x2)3

Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26. What is the

Sveta_85 [38]

Step-by-step explanation:

$5x + 27 \geqslant 6x + 26 \\ 5x - 6x \geqslant 26 - 27 \\ - x \geqslant - 1 \\ then \: change \: the \: sign \: into \: less \: than \: or \: equal \\ \frac{ - x}{ - 1} = \frac{ - 1}{ - 1} \\ x = 1$

Alicia draws a diagram to represent two forces, F1 and F2, acting on a body. The angle between the directions of the forces is 5

Nastasia [14]

Refer to the diagram shown below.

When the two forces F₁ and F₂ are added vectorially, the resultant force is R.
The angle x = 180° - 50° = 130°.

From the Law of Cosines, obtain
R² = F₁² + F₂² - 2F₁F₂ cos(130°)
Note that 2 cos(130°) = -1.2856.

Answer:
R = √(F₁²+ F₂² + 1.2856 F₁F₂ )
