Answer:

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos37° = $\frac{adjacent}{hypotenuse}$ = $\frac{48}{x}$

Multiply both sides by x

x × cos37° = 48 ( divide both sides by cos37° )

x = $\frac{48}{cos37}$ ≈ 60.1 → B

Answer:

Final velocity, v = 21.75 m/s

Step-by-step explanation:

Given that the relation between final velocity, initial velocity, acceleration and distance traveled is expressed as:

$v^2=u^2+2as$

Also, given that:

Initial velocity, u = 9 m/s

Acceleration, a = 7 m/ $s^2$

Distance, s = 28 m

To find:

Final velocity, v = ?

Solution:

The given relation between v, u, a and s is:

$v^2=u^2+2as$

We have the values of initial velocity, acceleration and distance traveled in the question statement. We just need to put all these values to find the value of final velocity.

Let us put all the values in the given equation and try to find final velocity, v:

$v^2=9^2+2\times 7 \times 28\\\Rightarrow v^2=81+14 \times 28\\\Rightarrow v^2=81+392\\\Rightarrow v^2=473\\\Rightarrow v=\sqrt{473}\\\Rightarrow v=21.75\ m/s$

So, the answer is:

final velocity, v = 21.75 m/s

Simplify: 3log3(-5) = A. -5 B. 3 C. 9 D. undefined

Usimov [2.4K]

Answer:

D. Undefined

Step-by-step explanation:

Since there is nothing that we can raise 3 to in order to get -5, we know that this is undefined. This is true of all logs with a negative number in front.
