It's true
collinear means they are on the same line so ST=SU
so if ST= 50 then SU=50 making T the midpoint of line that is 100

50 50
Answer:
Cubic trinomial
Step-by-step explanation:
The degree of a term is the sum of the exponents of its variables
- Quadratic: a polynomial of degree two
- Cubic: a polynomial of degree three
Therefore, -5x³ - 4x + 1 is a cubic (since the sum of the exponents is 3)
- monomial: a polynomial with exactly one term
- binomial: a polynomial with exactly two terms
- trinomial: a polynomial with exactly three terms
Therefore, -5x³ - 4x + 1 is a trinomial (as it has exactly 3 terms)
Answer:
c. 2; no
Step-by-step explanation:
The inner product is the sum of the products of corresponding vector components. It is a scalar value, not a vector value.
(3, 5)·(4, -2) = (3)(4) +(5)(-2) = 12 -10 = 2
When the inner product is non-zero, the vectors are not perpendicular. (The yes answers with a non-zero value can be rejected out of hand.)
The appropriate choice is ...
2; no
Answer:
x = 2 × 3 11/6 ≅ 2 × 7.5 ≅ 15
Explanation:
6 log₃ (0.5x) = 11
log₃ (0.5x) = 11/6
Here we make both sides the exponent of a base 3. It'll be the inverse function for the left hand side and cancel out the log.
3ˡᵒᵍ₃ ⁽ ⁰.⁵ˣ ⁾ = 3 11/6
0.5x = 3 11/6

<em>Hence the answer:</em>
<em></em>
x = 2 × 3 11/6 ≅ 2 × 7.5 ≅ 15
