<span>150 degrees. Let's assume the center camera is pointed to at an angle of 0 degrees. Since it has a coverage of 60 degrees, then it will cover the angles from -30 to +30 degrees. Now we'll continue to use the +/- 30 degree coverage for the other two cameras. The second camera is aimed at 45 degrees, so it's range of coverage is 15 degrees to 75 degrees (45 +/- 30). Notice that the range from 15 degrees to 30 degrees is covered by 2 cameras. Now the 3rd camera is pointed at -45 degrees, so its coverage is from -15 degrees to -75 degrees. It also has an overlap with the 1st camera from -15 to -30 degrees. The total coverage of all three cameras ranges from -75 degrees to 75 degrees. That means that an arc of 150 degrees in total is covered by all three cameras.</span>

hichkok12 [17]

Answer:

327692

Step-by-step explanation:

65536 = (-4)^{8} \\  \\ 65536 \times 5 = 327680 \\  \\ 327680 - 3(-4) = 327680 + 12 = 327692

According to the Order of Operations [GEMS(A)\BOMDAS\PEMDAS etc.], in this case, you evaluate the exponent BEFORE multiplying. This is a <em>common</em><em> </em><em>mistake</em><em> </em>people make.

I am joyous to assist you anytime.

If f(x) =3x2 and g(x)=4x3+1, what the degree of (f•g)(x)?<br><br> 2<br> 3<br> 5<br> 6
atroni [7]

f(x) = 3x²

g(x) = 4x³ + 1

f(g(x)) = 3.(4x³ + 1)²

As we know

(a + b)² = a² + 2.a.b + b²

So,

(4x³ + 1) = (4x³)² + 2.4x³.1 + 1² = 4x^6+8x^3+1

f(g(x)) = 3.(4x^6+8x^3+1)

The degree is the maximum exponent, so, 6.

Sandy hits a baseball that flies 114 meters through the air and into the stands.
Vilka [71]

Answer:

The average speed of the baseball is 26 m /s.

Step-by-step explanation:

Here, the total distance traveled by baseball = 114 meters

Time taken to cover this distance = 4.4 seconds

Now, \textrm{Average Speed} =  \frac{\textrm{Total Distnance traveled}}{\textrm{Total time taken}}

So, average speed = \frac{114 m}{4.4s} = 25.9m/s

and ,  25.9 m/s is approximately 26 m/s.

Hence, the average speed of the baseball is 26 m /s.
