f(x) = -38\\\\\implies 3x -5 = -38\\\\\implies 3x = -38 +5 \\\\\implies 3x = -33\\\\\implies x = -\dfrac{33}{3}\\\\\implies x = -11

If 1 cm represents 30 km on a map and colorado is shown by a 20cm by 15 cm rectangle on the map, what is the approximate actual
zubka84 [21]

Answer:

20*30km = 600km

15*30km = 450km

600km * 450km = 270000 km^2

Step-by-step explanation:

assuming 1cm --- 30km causes that 2cm --- 60km, 3cm --- 90km, 4cm --- 120km etc. Notice that number of km's is 30 times greater than the number of cm's on a map

using this logic, you calculate both real dimensions of Colorado by multiplying 20*30 = 600 km and 15*30 = 450km

Then we use a formula of an area of a rectangle A=a\cdot b assuming a=600km, \ b=450km and get A=600\cdot 450=270000km^2 which is an actual area of Colorado

Explanation:

Factorizing your equation we get

cot

(

x

)

=

0

so

cos

(

x

)

=

Find the value of x in the diagram shown below.
koban [17]

Answer:

a) <u>∡ADC = 270°</u>

b) <u>∠DAE = 38°</u>

Step-by-step explanation:

Using Inscribed Angle Theorem :

  • ∡ADC = 2 x ∠ABC
  • ∡ADC = 2 x 135°
  • <u>∡ADC = 270°</u>

Similarly :

  • ∠DAE = 1/2 x ∡DE
  • ∠DAE = 1/2 x 76°
  • <u>∠DAE = 38°</u>
