Answer:
16 Miles
Step-by-step explanation:
For every week you simply multiply the number of miles from the previous week by 2, therefore
Week 1: 1
Week 2: 2
Week 3: 4
Week 4: 8
Week 5: 16
Answer:
<h3>(k ∘ p)(x) = 2x²-16x+25</h3>
Step-by-step explanation:
<h3>(k ∘ p)(x) = 2(x-4)²-7</h3><h3 /><h3>(k ∘ p)(x) = 2(x²-8x+16)-7</h3><h3 /><h3>(k ∘ p)(x) = 2x²-16x+32-7</h3><h3 /><h3>(k ∘ p)(x) = 2x²-16x+25</h3>
Step-by-step explanation:
in such a case, where we have all the sides and need angles, the best tool is the extended Pythagoras (for general triangles and not just for right-angled ones) :
c² = a² + b² - 2ab×cos(C)
c is the side opposite of angle C.
the side opposite of B is CA.
so, we have
220² = 100² + 160² - 2×100×160×cos(B)
48,400 = 10,000 + 25,600 - 32,000×cos(B)
12,800 = -32,000×cos(B)
cos(B) = -12,800/32,000 = -0.4
B = 113.5781785...° ≈ 114°
