What is the range of y= x + 2?

Answers

Answer:

A) all real numbers greater than or equal to 2

Domain: [tex]x\geq 0[/tex]

Step-by-step explanation:

The variable in the radical x cannot be less than 0 as that wouldn’t be defined. So, the maximum that x can be is 0, and [tex]y=x+2[/tex]. So, 0+2=2, and y is greater than or equal to 2.

Domain is x is greater than or equal to 0 because you cannot square a negative. So, it must not be less than 0. It could be 0 because square root of 0 is just 0.

Write and solve an equation to find the values of d and w .

Answers

Answer:

d = 65°

w = 55°

Step-by-step explanation:

m∠DAC +∠m∠CAB = 60

m∠DAC + 35 = 60

m∠DAC = 25

m∠DAC + d = 90

25 + d = 90

d = 65°

m∠GAF + w + d = 180

60 + w + 65 = 180

w + 125 = 180

w = 55°

Answers

Answer:

Step-by-step explanation:

Let the no be x

By the conditions given ,

2x + 6x = 72

8x = 72

x = 72/8

x = 9

therefore the no is 9

[tex](2 \times x) + (6 \times x) = 72 \\ 2x + 6x = 72 \\ 8x = 72 \\ x = 72 \div 8 \\ x = 9[/tex]

As an unknown drone is detected by a radar dish hovering over a secure location in Washington dc the initial reading of the radar dish was detects the drone .The reading of the radar dish indicates an angle of elevation of 60 to the drone

Answers

Answer:

60° ; 30°

27.71 km

Step-by-step explanation:

Since we have a right angled triangle, and also the sum of the angles in a triangle is 180°

Angle of elevation is given as 60°

Hence, we have :

90°+60°+x ° = 180°

x = 180 - 150

x = 30°

The two acute angles are 60° and 30°

The altitude, h of the drone can be obtained thus :

Using trigonometry :

Sin θ = opposite / hypotenus

Sin 60 = h / 32

h = 32 * sin 60

h = 27.71 km
