Answer:
-1 1/6
1 11/16
1 5/6.
Step-by-step explanation:
-5 5/6 ÷ 5
= -35/6 * 1/5
= -7/6
= - 1 1/6.
-4 1/2 ÷( -2 2/3)
= -9/2 / -8/3
= -9/2 * -3/8
= 27/16
= 1 11/16.
-6 7/8 ÷ (-3 3/4)
= -55/8 / -15/4
= -55/8 * -4/15
= 11/6
= 1 5/6.
Answer: C
Step-by-step explanation:
the inner product of (a,b) * (c,d) is ac + bd
= 3 * 4 + 5 * -2
= 12 - 10
= 2
since the inner product is not 0, the vectors are not perpendicular
Answer:
It would take them 12 minutes.
Step-by-step explanation:
<u>To solve this, we need to use our trigonometric equations</u>
<em>⇒ look at the diagram attached</em>
<u>Let's examine what the problem wants:</u>
- the length of the side adjacent to the 58-degree angle
<u>Let's examine what the problem gives us:</u>
- the length of the side opposite to the 58-degree angle
- the angle that has a measure of 58-degrees
<u>Let's solve:</u>
![tan(58)=\frac{22}{x} \\22=x*tan(58)\\x=\frac{22}{tan(58)} \\x=13.75](https://tex.z-dn.net/?f=tan%2858%29%3D%5Cfrac%7B22%7D%7Bx%7D%20%5C%5C22%3Dx%2Atan%2858%29%5C%5Cx%3D%5Cfrac%7B22%7D%7Btan%2858%29%7D%20%5C%5Cx%3D13.75)
<u>Answer: 13.8</u> (<em>rounded to nearest tenth)</em>
<u>Hope that helps!</u>
