Answer:

  • 43°

Step-by-step explanation:

<u>We observe on the picture that:</u>

  • (12x + 11)° and  47°  are  vertical angles and vertical angles are equal as per definition
  • Angle w° is complementary angle with (12x + 11)° and complementary angles add to 90° as per definition

<u>Therefore</u>

  • w = 90°- (12x + 11)°
  • w = 90° - 47°
  • w = 43°

Answer:

w=67°

Step-by-step explanation:

First you solve for x. 12x+11=x. X would be 1. Then you plug in 1 for x and add the w to the equation. 12(1)+11+w=90. after solving that you will get the total for w. which should be 67°

8 A test rocket is fired and follows a path described by y = 0.1x(200 – x). The height is y metres above
balandron [24]

Answer:

a) The rocket travels 200 meters horizontally.

b) The height of the rocket mid-flight is of 1000 meters.

Step-by-step explanation:

Height of the rocket:

The height of the rocket, in meters, after an horizontal distance of x, is given by:

y = 0.1x(200 - x)

a) How far does the rocket travel horizontally?

This is x when y = 0. So

0.1x(200 - x) = 0

Then

0.1x = 0

x = 0

And

200 - x = 0

x = 200

So

The rocket travels 200 meters horizontally.

b How high does the rocket reach mid-flight?

This it the height y when x = 0, so:

y = 20*100 - 0.1*100^2 = 1000

The height of the rocket mid-flight is of 1000 meters.
