Answer:

true

Step-by-step explanation:

y = 5x+6

To find the inverse, exchange x and y

x = 5y+6

Solve for y

x-6 = 5x+6-6

x-6 = 5x

Divide by 5

x/5 - 6/5 = 5y/5

1/5x - 6/5 = y

The inverse is (x-6)/5

A scuba diver descends in the water at a rate of 23 1/2

Makovka662 [10]

The scuba diver's position relative to sea level after the 4.6 minutes is 5.1 ft.

Given:

A scuba diver descends in the water at a rate of 23 1/2 feet per minute for 2.6 minutes.

A scuba diver ascends at a rate of 28 feet per minute for 2 minutes after seeing a big fish.

To find :

The scuba diver's position relative to sea level after the 4.6 minutes.

Solution:

Rate of a scuba diver descending in the water for 2.6 minutes = $R _1$

$R_1= 23\frac{1}{2}ft/min=\frac{47}{2} ft/min$

Distance covered by a scuba diver in 2.6 minutes = $d_1$

$d_1=R_1\times 2.6min=\frac{47}{2} ft/min\times 2.6 min=61.1 ft$

Rate of a scuba diver ascending for 2 minutes = $R _2$

$R_2= 28ft/min$

Distance covered by a scuba diver in 2 minutes = $d_2$

$d_2=R_2\times 2min=28 ft/min\times 2 =56 ft$

The position of scuba diver after 4.6 minutes relative to sea level:

$d_1-d_2=61.1 ft-56 ft=5.1ft$

The scuba diver's position relative to sea level after the 4.6 minutes is 5.1ft.

Dillon says that 4b and -2b are not like terms

olganol [36]

He is wrong because as long as they have the same terms/ variables behind the number it doesn’t matter about if it is positive or negative

I will give branliest

Evgesh-ka [11]

Step-by-step explanation:

Height of ladder = 12ft .

Here perpendicular is height to which it reaches .

When angle is 30⁰ :-

=> sin 30⁰ = H/12

=> ½ = H/12

=> H = 12/2

=> H = 6m ( ans )

When Angle is 45⁰ :-

=> sin45⁰ = H/12

=> 1/√2 = H/12

=> H = 6*√2*√2/√2

=> H = 6√2 m ( ans )

When angle is 60⁰ :-

=> sin60⁰ = H/12

=> √3/2 = H/12

=> H = 12 *√3/2

=> H = 6√3 ( ans )

hope it helped !
