Answer:
9.28 × 10⁻⁴ cm/year.
Step-by-step explanation:
Let d(t₀) represent the initial position of Kauai island = 0 km from the hot spot. at time t = 0 million years. Let d(t₁) represent its final position at time t₁ = 5.1 million years later in the North - west direction. d(t₁)=473 km = 4.73 × 10³ cm. The average speed v = total distance/ total time =[d(t₁) - d(t₀)]/t₁₋t₀ = (4.73 × 10³ - 0)/(5.1 × 10⁶ - 0) = 4.73/5.1 × 10³⁻⁶ = 9.275 × 10⁻⁴ cm/year ≅ 9.28 × 10⁻⁴ cm/year
Answer:
=49.15 cm²
Step-by-step explanation:
To find the area of the triangle we use the sine formula
A= 1/2ab Sin∅
where A is the area a and b are the lengths of two sides that intersect at a point and ∅ is the angle between them.
a=10 cm
b= 12 cm
∅=55°
A= 1/2×10×12×Sin 55
=49.15 cm²
Answer: Choice A) Graph crosses y axis at (0,-5), decreases from x = -10 to x = -2, constant from x = -2 to x = 10
--------------------------------------------------------
The statement "The graph crosses the y axis at (0,-5)" is a true statement because the red line crosses at -5 on the y axis. This allows us to rule out choice D. Choice C can be ruled out because the graph never increases. The graph would have to be moving uphill, as you read from left to right, to be increasing. Choice B is false because the junction point is at x = -2 and not x = 0.
Answer:
$27
Step-by-step explanation:
0.3 x 90 = $27
30% of your money is $27, so the football must've cost $27.
