The first option is the correct choice of answers.
Answer:
B
Step-by-step explanation:
A 90 degree rotation would be a rotation of 90° about the origin. Knowing this, we can eliminate C since it is a 180° rotation. We can also eliminate A, as it would be a 0° or 360° rotation. This leaves us with B and C.
A counterclockwise rotation would be one that goes the opposite direction of the rotation of the hands of a clock. A 90° counterclockwise rotation would yield triangle B, making that our answer.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
45.2 × 10⁰ = 45.2 (a⁰ = 1 )
45.2 × 10¹ = 452
45.2 × 10² = 4520
45.2 × 10³ = 45200
X = 0.6x + 384 |subtract 0.6x from both sides
0.4x = 384 |divide both sides by 0.4
x = 960
Answer:
a25 = -134
Step-by-step explanation:
For first term a1 and common difference d, the formula for the n-th term is ...
an = a1 + d(n -1)
You want to evaluate this for n=25, a1=-14, d=-5. Filling in the numbers and doing the arithmetic, you get ...
a25 = -14 -5(25 -1) = -14 -120
a25 = -134
