You are watering a garden. The height h (in feet) of water spraying from the garden hose can be modeled by h(x)=−0.1x2+0.7x+3, w
lawyer [4008]

Answer:

g(x) = -0.1x^2 + 0.5x + 3.6

Step-by-step explanation:

Given

h(x) = -0.1x^2 + 0.7x + 3

Required

Find the updated function

The problem specifies that the water should land 1 ft further away.

This means we need to use x + 1

Consequently, in the initial function, we will replace x with x + 1 in h(x) = -0.1x^2 + 0.7x + 3

Thus, we obtain:

h(x + 1) = -0.1(x + 1)^2 + 0.7(x + 1) + 3

Expand the Parenthesis

h(x + 1) = -0.1(x + 1)(x + 1) + 0.7(x + 1) + 3

h(x + 1) = -0.1(x^2+2x+1) + 0.7(x + 1) + 3

h(x + 1) = -0.1x^2-0.2x-0.1 + 0.7x + 0.7 + 3

Combine Like Terms

h(x + 1) = -0.1x^2-0.2x + 0.7x + 0.7 + 3-0.1

h(x + 1) = -0.1x^2 + 0.5x + 3.6

The resulting function is:

g(x) = h(x + 1) = -0.1x^2 + 0.5x + 3.6

g(x) = -0.1x^2 + 0.5x + 3.6

A car entered a roundabout from Mason Avenue, traveled 280 feet, then turned onto Perry Street. If the roundabout has a diameter
Leona [4166]

Answer:

The rotation angle measures 214°.

Step-by-step explanation:

Arc length formula:

The arc length equals the radius multiplied by the central angle (in radians).

L= rθ

L= Arc length

r= Radius

θ= Central angle (in radians).

Given L= 280 feet and diameter =150 feet.

Radius =\frac{150}{2} feet =75 feet

L= rθ

\Rightarrow \theta =\frac{L}{r}

\Rightarrow \theta =\frac{280}{75} radians.

We know that,

π radian= 180°

\Rightarrow 1 \ radian= \frac{180^\circ}{\pi}

\Rightarrow \frac{280}{75} \ radian = \frac{180^\circ}{\pi}\times \frac{280}{75}

                      = 214°

The rotation angle measures 214°.

Enter the expression N0e−λt, where N0 is N-naught (an N with a subscript zero) and λ is the lowercase Greek letter lambda.
tester [3916]
The problem requests that we express the formula in your inquiry where N0 symbolizes N-naught, and the letter represents the lowercase Greek letter lambda. Therefore, the optimal response or formulation would indicate that lambda denotes the wavelength for this expression. I trust this information meets your expectations.

I believe this situation pertains to "two individuals," though I consider a 16-inch pizza to be more than sufficient. Apologies if I'm mistaken.
