Answer:
-125
Step-by-step explanation:
Step 1: Find g(-1)
g(x) = -5x²
g(-1) = -5(-1)²
g(-1) = -5(1)
g(-1) = -5
Step 2: Find g(-5)
g(-5) = -5(-5)²
g(-5) = -5(25)
g(-5) = -125
Answer:
Step-by-step explanation:
Given:
Linear transformation,
defined as
To Show: T is invertible
To find:
We know that Standard Basis of R² is
So, The matrix representation of T is
Now, Determinant of T = 1 - (-1) = 1 + 1 = 2 ≠ 0
⇒ Matrix Representation of T is Invertible matrix.
⇒ T is invertible Linear Transformation.
Hence Proved.
let,
Add (1) and (2),
Putting this value in (1),
Now,
Therefore,
It well be b.and c. For the question.
Answer:
79.5
Step-by-step explanation:
35 correct = 35x2.5=87.5
32 wrong = 32x-0.25=-8
no. of pts = 87.5+(-8) = 79.5
