S_A_V [24]3 years ago
4 0

Answer:

Step-by-step explanation:

Using the cosine theorem:

c^{2} =a^{2} +b^{2} -abcos\beta

952^{2} =560^{2} +575^{2} -560*575cos\beta

\beta =cos^{-1} (\frac{560^{2}+575^{2}-952^{2}   }{2*560*575} )

The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees

ivann1987 [24]

Answer:

- 8x + 3

Step-by-step explanation:

(f + g)(x)

= f(x) + g(x)

= - 5x + 3 + (- 3x)

= - 5x + 3 - 3x ← collect like terms

Sergeu [11.5K]

Answer: .34 ≤ x ≤ .81

Step-by-step explanation:

An inequality is writted like __ ≤ x ≤ ___

Since the humming bird can fly between .34 and .81 we use the the less than or equal to sign because it can fly max .81 mpm or less than that. with a minimum speed of .34 mpm.

Clare volunteers at a local library during the summer. Her work includes putting labels on 750 books. How many minutes will she
Lubov Fominskaja [6]

Answer:

75 minutes

Step-by-step explanation:

Assuming that Clare will not take a break throughout the session

10 books=1 minute

750 books= x minutes

Cross multiplying to find the value of x

10x books=750 books minutes

Making x the subject

x=750 books minutes/(10 books)

x=75 minutes

This translates to 1 hours and 15 minutes

Therefore, Clare will require 75 minutes
