Evaluate cos0 if sin0= sqrt(5)/3<br><br> a. 9/5<br> b. 2/3<br> c. 5/9<br> d. 3/2
Evgesh-ka [11]

Solution given:

\sin( \alpha )  =   \frac{\sqrt{5} }{3}

so

P=√5

h=3

b=\sqrt{3 {}^{2} -  \sqrt{5}  {}^{2}  }

b=2

so

\cos( \alpha )  =  \frac{b}{h}  =  \frac{2}{3}

Note

\alpha  = 0

<u>b</u><u>:</u><u>⅔</u>

A truck that can carry no more than 6600 lbs is being used to transport refrigerators and upright pianos. each refrigerator weig
ZanzabumX [31]

Answer:

(a). 300r + 425p ≤ 6,600

(b). No, it’s not considered overweight

Step-by-step explanation:

In this question, we are to write an equation that shows the number of refrigerators and pianos the truck could carry.

Let the number of refrigerators be r and the number of pianos be p

By using their individual weights, the equation is as follows;

300r + 425p ≤ 6,600

To the second question, we want to consider if 10 refrigerators and 8 pianos are overload.

To get this, we simply multiply the number of each by their individual weights;

That would be;

300(10) + 425(8) = 3000 + 3,400 = 6,400 lbs

This is not considered overweight as it is less than 6,600 lbs
