Answer:
X ¹/₅
Step-by-step explanation:
X ⁷/₁₀
X ¹/₂
apply the exponent rule:
= X ⁷/₁₀ - ¹/₂
= X ¹/₅
Answer:
TRUE
Step-by-step explanation:
We are given 2 triangles, ∆ABC and ∆DEF.
For the two trinagles to be considered similar, both must have their set of corresponding angles congruent to each other. That is, their corresponding angles are equal.
From the information given, the following are the set of corresponding angles:
<B = <E = 31°
<B = <D = 90°
<C = <F = 59° [180 - (90+31)]
The corresponding angles of both triangles are congruent. Therefore, it is guaranteed that ∆ABC is similar to ∆DEF (∆ABC ~ DEF).
Answer: 2
Steps:
f(-2) = 1/2x^2
f(-2) = 1/2(-2)^2
f(-2) = 1/2(4)
f(-2) = 2
Answer:
<h2>A) 32</h2>
Step-by-step explanation:
From 1 to 10 we have 4 numbers which are {2,4,6,8}
From 10 to 20 we have 4 numbers which are {12,14,16,18}
