                                                  (17)

Answer:

h(-6) = -457            

Step-by-step explanation:

Given the function

h(x)= 72 x-25

Put h = -6 to in the function

h(x)= 72 x-25

h\left(-6\right)=\:72\left(-6\right)-25

           =-432-25

           =-457

Therefore,

h(-6) = -457                            

                                                   (18)

Answer:

g(2)=25            

Step-by-step explanation:

Given the function

g\left(x\right)\:=\:5x^2\:+\:4x\:-\:3

g\left(2\right)\:=\:5\left(2\right)^2\:+\:4\left(2\right)\:-\:3

        = 20 + 8 - 3

        = 25

Therefore,

g(2)=25

From Alexa's eyesight to the top of the tree has an angle of 56.789 degrees and its distance of 23.45 feet. Match the following
Marat540 [252]

Answer:

Distance between Alexa and tree = 12.844 ft

Height of tree = 19.620 + height of eyesight from ground

Perimeter of triangle formed = 55.914 ft

Step-by-step explanation:

From the given data, the attached image is drawn ( refer attachment)

Assume

Height of eye line as h_{A}, height of tree as  h_{T}, distance of tree from Alexa as X and vertical distance between eye line and top of tree is y.

To find: distance of tree from Alexa

consider triangle ATE. Here

X = 23.45 * cos (56.789^{o}) = 12.844 ft

y = 23.45 * sin (56.789^{o}) = 19.620 ft

Hence distance of tree from Alexa = 12.844 ft

Height of tree  h_{T} = y + h_{A}

                               = 19.620 + h_{A}

Perimeter of triangle = X + Y + 23.45 ft

                                     = 12.844 ft +19.620 ft + 23.45 ft

                                     = 55.914 ft

frez [133]

Answer:

-3/2

Step-by-step explanation:

The slope is found by

m = ( y2-y1)/(x2-x1)

Using the points (-4,11) and ( 0,5)

m = ( 11-5)/( -4-0)

  = 6/-4

  = -3/2
