A=10ft because A is 8ft so round that to the nearest ten your answer is 10ft

You are still in the cosine law. All that changes is that 17^2 is put on the left by itself.


a^2 = b^2 + c^2 - 2bc * cos(A) Solve for A

17^2 = 8^2 + 16^2 - 2*8*16* cos(A)

289 = 64 + 256 - 256*cos(A)

289 = 320 - 256*Cos(A)

289 - 320 = - 256*Cos(A)

-31 = - 256 * Cos(A)

-31 / - 256 = cos(A)

0.1211 = cos(A)

cos-1(0.1211) = A

83.05 = A

Can anyone please help!!!
quester [9]

Answer:

Question 9

(a) The distance, Jalaj walks in one day is 4.4 km

(b) The amount Jalaj raises after walking for 22 km at the end of the 5 days is $8

Question 10

(b) The difference between the largest and smallest areas is 2,400 m²

Step-by-step explanation:

Question 9

(a) The distance Jalaj walks in 5 days = 22 km

Whereby Jalaj walks equal distance every day, we have;

The distance, Jalaj walks in one day = 22 km/5 days = 4.4 km/day

The distance, Jalaj walks in one day = 4.4 km

(b) The amount he raises for every kilometer he walks = $1.60

The amount he raises after walking for 22 km at the end of the 5 days = 5 × $1.60  = $8

Question 10

(b) The given side length of the square = 120 meters to the nearest 10 meters

Therefore;

The maximum dimension for the side length of the square = 120 + 10/2 = 125

The largest possible area of the square, A_l = 125 m × 125 m = 15,625 m²

The minimum dimension for the side length of the square = 120 m - 10 m/2 = 115 m

The smallest possible area of the square, A_s = 115 m × 115 m = 13,225 m².

The difference between the largest and smallest areas, A_l - A_s = 15,625 - 13,225 = 2,400 m².

Given g(x) = -x – 4, find g(-5).
riadik2000 [5.3K]

The value of g(-5) from the given. function; g(x) = -x – 4 is; g(-5) = 1

<h3>Evaluation of functions</h3>

The given function is;

  • g(x) = -x – 4

Hence, the value of g(-5) can be obtained by substituting -5 for x in the function as follows;

  • g(-5) = -(-5) -4

  • g(-5) = 5 -4

  • g(-5) = 1.

<span>6( 5-8x) +12= -54 
30-48x+12=-54 this comes from distributing(multiplying) 6x5 and 6 times -8x
30+12-48x=-54 you have to add the coefficients 30+12
