A park ranger observed the number and ages of children who visited the park on a Friday morning. The results of his observations
aleksandr82 [10.1K]
ANSWER

The number of children between the ages of 9 and 15 who visited the park is
20


EXPLANATION


The number of children between the ages of 9 and 15 who visited the park are those within the age group 9 to 12 and 12 to 15.


We can from the graph that, the height of the bar that corresponds to the age group 9 to 12

= 14
and the height of the bar that corresponds to the age group 12 to 15

= 6


The sum of the two frequencies

= 14 + 6 = 20

Find an equation of the tangent line to the curve at the given point. y = 3x3 - x2 + 2, (1, 4)
ICE Princess25 [194]

y = 7x - 3

Note the gradient of the tangent is the derivative of y at x = 1

Differentiate using the power rule

\frac{d}{dx}(ax^{n}) = nax^{n-1}

y = 3x³ - x² + 2

\frac{dy}{dx} = 9x² - 2x

x = 1 : \frac{dy}{dx} = 9 - 2 = 7 ← gradient of tangent

equation in point- slope form, using m = 7 and (a, b) = (1, 4)

y - 4 = 7(x - 1) ← point-slope form

y - 4 = 7x - 7

y = 7x - 3 ← in slope-intercept form

A carpenter is building a rectangular room with a fixed perimeter of 300 ft. what dimensions would yield the maximum​ area?
Inessa05 [86]

Perimeter = 2(Length) + 2(Width)

300 = 2L + 2W → 150 = L + W → 150 - L = W

Area = Length · Width

A_{max} = L(150 - L) → A_{max} = 150L - L²

There are 2 different methods for solving (depending on which math course you are taking).

<u>Calculus</u>: find the derivative, set it equal to zero, and solve for L.

A_{max} = 150L - L² → 0 = 150 - 2L → 2L = 150 → L = 75

<u>Algebra</u>: find the vertex.

A_{max} = - L² + 150L → L = -b/2a → L = -150/2(-1) → L = 75

Once you solve for L, plug it into the Perimeter equation to solve for W:

150 - L = W → 150 - 75 = W → W = 75

Answer: 75ft x 75ft
