More on Areas. Farmer Jones, and his wife, Dr. Jones, both mathematicians, decide to build a fence in their field to keep the sh
Olin [163]

Answer:

Area covered by the fences will be 16.1 unit²

Step-by-step explanation:

Let the first parabola is represented by the function f(x) = 6x²

and second parabola by g(x) = x² + 9

point of intersection of the graphs will be determined when f(x) = g(x)

6x² = x² + 9

5x² = 9

x² = 1.8

x = ± 1.34

Now we will find the area between these curves drawn on the graph.

Area = \int_{-1.34}^{1.34}[f(x)-g(x)]dx=\int_{-1.34}^{1.34}[6x^{2}-(x^{2}+9)]dx

= \int_{-1.34}^{1.34}(5x^{2}-9)dx

= [\frac{5}{3}x^{3}-9x]_{-1.34}^{1.34}

= [\frac{5}{3}(-1.34)^{3}-9(-1.34)-\frac{5}{3}(1.34)^{3}+9(1.34)]

= [-4.01+12.06-4.01+12.06]

= 16.1 unit²

You are saving money to buy a used car. You deposit $2,500 in an account that earns interest compounded annually. The expression
seraphim [82]

Answer:

r= [(\frac{A}{2500}) ^\frac{1}{2} -1]

Step-by-step explanation:

Given data

Principal = $2500

time t= 2 years

Required

the rate r

Given the expression for the balance 2500(1+r)^2

Hence

A= 2500(1+r)^2

we can make r subject of formula

r= [(\frac{A}{P}) ^\frac{1}{t} -1]

r= [(\frac{A}{2500}) ^\frac{1}{2} -1]

Hence, for any value of A, we can find the rate using the expression above

How many sides does a regular (equal sides and equal angles) polygon have if each exterior angle measures 24°? # of sides =?
lubasha [3.4K]
If the measure of each exterior angle is 24, the measure of each interior angle is then 180-24=156
the sum of the interior angles of a polygon is (n-2)*180, n is the number of sides
(n-2)*180=156*n
180n-360=156n
24n=360
n=15
the polygon has 15 sides

What is the LEast common multiple?
belka [17]
The least common multiple (LCM) of a set of numbers is the lowest value that all of the numbers can be divided by and have a result of a whole number.

In this case, the least common multiple is 21 because 21/7=3 and 21/21=1.
