Answer:

The correct answer is 3πcm

Step-by-step explanation:

The length of an arc is calculated using the formula P=∅/360×2πr

where ∅is the angle the arc subtends at the center of the circle, and r is the radius of the circle of which the arc is part.

2r gives the diameter which from the diagram corresponds to AB=36 cm

therefore P=30/360×π×36

=3πcm

Renting roller blades costs a flate fee of $5 plus an additional $2.50 per hour. Write a linear equation that models this.

Kobotan [32]

Answer:

Linear equation : y = 2.50h + 5

Step-by-step explanation:

Given that:

Fee for renting roller blades = $5

Per hour charges = $2.50

Let,

h be the number of hours roller blades were rented

y be the total amount

Total amount = Per hour charges * Number of hours + Flat fee

y = 2.50h + 5

Hence,

Linear equation : y = 2.50h + 5

The light intensity I (in lumens) at a depth of x feet in Lake Elizabeth is given by the formula log (StartFraction Upper I Ove

antiseptic1488 [7]

Answer:

The light intensity at a depth of 24 feet is 3.0143 lumens.

The light intensity will be 7 lumenus at the depth of 9.3732 feet approximately.

Step-by-step explanation:

Consider the provided formula.

$log(\frac{I}{12})=-0.025x$

Where I is the intensity of light and x is the depth.

Part (A) Find the light intensity at a depth of 24 feet.

Substitute x=24 in above formula.

$log(\frac{I}{12})=-0.025(24)$

$log(\frac{I}{12})=-0.6$

$\frac{I}{12}=10^{-0.6}$

$\frac{I}{12}=0.2512$

$I=3.0143$

Hence, the light intensity at a depth of 24 feet is 3.0143 lumens.

Part (B) At what depth is the light intensity 7 lumens

Substitute I=7 in above formula.

$log(\frac{7}{12})=-0.025x$

$-0.23433=-0.025x$

$0.23433=0.025x$

$x=\frac{0.23433}{0.025}$

$x=9.3732$

Hence, the light intensity will be 7 lumenus at the depth of 9.3732 feet approximately.

Tju [1.3M]

Answer:

9.23 x 10^-5

Step-by-step explanation:

But the decimal point behind the first number that isn't 0

Then count how many times you moved it and that is the exponent on the ten

If you moved the decimal right, it is negative exponent

If you moved the decimal left, it is a positive exponent
