Phythagoras theorem:
hypotenuse²=leg₁²+leg₂²
Data:
leg₂=7.2
hypotenuse=11.1
Therefore:
(11.1)₂=leg₁² +(7.2)²
123.21=leg₁²+51.84
leg₁²=123.21 - 51.84
leg₁²=71.37
leg¹=√(71.37)
leg₁=8.4
Answer: b=8.4
Answer:
B) Beth went back toward her origin.
Step-by-step explanation:
From 0 to 6, the graph increases. The dependent variable in this case is position and the independent variable is time; this means for this portion of the graph, as time increases the position increases as well.
From 6 to 10, the graph decreases. As time increases the position decreases. This means she goes back to her original position.
A perfect square trinomial is the result in algebraic form which is obtained by solving the squared binomial expression. Kylie did not understand that this is a perfect square trinomial and she did not determine the product correctly. Thus the option C is the correct option.
Given information-

When dividing, exponential powers are subtracted. When multiplying, power are added the base remains the same if the two bases are the same number. If they are different, the bases are multiplied and the same power is simply kept. With this in mind, let us solve this question!
6^3 × 2^6 / 2^3 ----- Multiplication or division can be done first. I do division because it's easier that way. 6-3 = 3
6^3 * 2^3 ------ Multiply bases and keep the power.
B.) 12^3
Hope this helps!
