Answer:

30° or 60°

Step-by-step explanation:

Range of a projectile on level ground is:

R = v₀² sin(2θ) / g

Given R = 15 m and v₀ = 13 m/s:

15 m = (13 m/s)² sin(2θ) / (9.8 m/s²)

sin(2θ) = 0.870

2θ = 60.4° or 119.6°

θ = 30.2° or 59.8°

Rounded, the launch angle required is either 30° or 60°.

It’s hard to tell due to no labels, but these are your angles due to the equal angles theorem and a few other theorems. Hopefully with this image you can hopefully find your answer. You may need to add angles together depending on what you are looking for. And possible even figure out what angle measure would make a (180 degree) triangle.
Hope this helped

Answer:  

15.59 cm^2  

Step-by-step explanation:  

Given formula for area= √(3s^4)/4  

We have, a=6cm  

Area= √(3s^4)/4 = √(3*6^4)/4 =√(3*1296)/4 =√3888/4 ≈ 62.35/4 ≈ 15.59 cm^2

Answer:

the probability having no customers are in the system is 0.375

Step-by-step explanation:

The computation of the probability having no customers are in the system is as follows;

Given that the arrival rate is 1.25 customers per minute

The Service rate is 2 customers per minute

Based on the above information, the probability is

=P_0\\\\=(1-\frac{\lambda }{\mu })\\\\=(1-\frac{1.25}{2})\\\\=1-0.625\\\\= 0.375

Hence, the probability having no customers are in the system is 0.375

Need additional math help 50 pts
Alex17521 [72]

Answer:

12

Step-by-step explanation:

This thing to know about this question is that angle 1 and angle 3 are actually the same.

When two lines intersect, the opposite angles such as that shown in 1 and 3 are equal to each other.

So what you can do is set angle 1 and 3 equal to each other like so:

5x+10 = 70

Then solve for x

5x+10 = 70

5x = 60

x = 12
