Answer:
A, C, D
Step-by-step explanation:
All three triangles can be proved congruent, so corresponding angles are congruent.
∆JKL ≅ ∆MNO ≅ ∆PQR
__
So, the statements that are true are ...
A) rigid motion can map ∆JKL to ∆MNO
C) ∆JKL can be proved congruent to ∆PQR
D) ∠N can be proved congruent to ∠Q
_____
<em>About the other choices</em>
B. When triangles are congruent, there is some rigid motion that maps one to the other. It is false to say there is none such.
E. ∠L has a measure of 65° (not 55°), as do the corresponding angles in the other triangles.
Split in half 20 squared + 10 squared
then find the square root of the answer
10-/5
Answer:
1020
Step-by-step explanation:
1200*.15=180
Then
1200-180=1020 Ans
Answer:
A. 4
B. 1
Step-by-step explanation:
The degree of a one-variable polynomial is the largest exponent of the variable.
__
<h3>A.</h3>
For f(x) = x^4 -3x^2 +2 and g(x) = 2x^4 -6x^2 +2x -1, the sum f(x) +a·g(x) will be ...
(x^4 -3x^2 +2) +a(2x^4 -6x^2 +2x -1)
= (1 +2a)x^4 +(-3-6a)x^2 +2ax -a
The term with the largest exponent is (1 +2a)x^4, which has degree 4. This term will be non-zero for a ≠ -1/2.
The largest possible degree of f+ag is 4.
__
<h3>B.</h3>
The polynomial sum is ...
f+bg = (1 +2b)x^4 +(-3-6b)x^2 +2bx -b
When b = -1/2, the first two terms disappear and the sum becomes ...
f+bg = -x +1/2 . . . . . . a polynomial of degree 1
The smallest possible degree of f+bg is 1.
