Answer:
Step-by-step explanation:
When dividing two exponents (of the same bases) you subtract the exponents. When there is an exponent to an exponent, you multiply the to exponents.
Given : A submarine descends at a rate of 2.6 kilometers per hour.
If the ocean floor is 6.24 kilometers below sea level,
To Find : how long will it take the submarine to descend to the ocean floor?
Solution:
The submarine descends at a rate of 2.6 kilometers per hour.
Speed = 2.6 km/hr
The ocean floor is 6.24 kilometers below sea level,
Distance to be covered = 6.24 km
Time= Distance / Speed
= 6.24 / 2.6
= 2.4 hr
The submarine will take 2.4 hrs to descend to the ocean floor
<span>The area of a triangle is 6.75 m^2
=> (1/2) x base x height=</span>6.75 m^2
=>(1/2) x 3 x <span>height = </span>6.75
=><span>height = (</span>6.75x2)/3= 4.1
so the height is 4.1m
Answer:
Step-by-step explanation:
From the given right angle triangle,
the hypotenuse of the right angle triangle is 13
With m∠65° as the reference angle,
y represents the adjacent side of the right angle triangle.
x represents the opposite side of the right angle triangle.
To determine the value of x, we would apply the sine trigonometric ratio which is expressed as
Sin θ = opposite side/hypotenuse. Therefore,
Sin 65 = x/13
x = 13Sin65 = 13 × 0.906
x = 11.8 to the nearest tenth
