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
Answer:
Even function
Step-by-step explanation:
Both powers of x in f(x) = -3x^4 + 7x^2 are even, so f(x) = -3x^4 + 7x^2 is an even function.
Answer:
In other words, the surface area is the sum of all the areas of all the shapes that cover the surface of the object. On the other hand, the lateral surface area refers to the area of the sides of a shape , excluding its base and top area.
Step-by-step explanation:
Answer:
nonlinear
Step-by-step explanation:
The word 'linear' means something having to do with a line. On a Cartesian Plane, a linear characteristic is a feature wherein the graph is a straight line. The line can cross in any direction, but it's always an instant line. A non-linear function has a shape that isn't an immediate line
The graph is nonlinear because it is not a straight line.

Answer:
Mass =12.4g
∆T= 1064-26
=1038°C
H=mc∆T + mlf
where c =Specific heat of substance
lf= Latent heat of Fusion
m=Mass
∆T=Temp. change
Substituting
H= 12.4(0.1291)(1038) + 12.4(63.5)
H= 1661.67 + 787.40
H=2449.07J
