Answer:
435.8 feet
Step-by-step explanation:
law of sines:
*sin 90°/1 = sin 35°/250
cross-multiply to get:
x·sin35° = 250
x = 250/sin35°
x = 435.8
*we can assume the ocean surface and the reef 250 feet below forms a 90° angle

(120 × 0.4) - 10 - 15 =23/120 = 19.16666667
Answer:
g(x) = x is the base function.
To shrink it vertically by 1/2, make 1/3 the coefficient of the variable x.
To shift it 4 units to the right, subtract 4 from within the squared variable.
To shift 5 units down, subtract 5 from the entire function.
Step-by-step explanation:
Answer:
The path length is the same for the small and large semicircles.
Step-by-step explanation:
The distance around the large semicircle = 1/2 * π * diameter
= 1/2*8*π
= 4π m.
The distance around the 2 smaller semicircles
= 1/2 * 4 * π + 1/2 * 4 * π
= 2π + 2π
= 4π m.
Answer: 200 times larger
Explanation (6*10^5)/(3*10^3)=2*10^2
2*100=200
The other answer was wrong because in order of operations (PEMDAS), exponents come before multiplication.
