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

Option A. 5/8 is the correct answer.

Step-by-step explanation:

Square root by factorization will be used to solve this question.

Given

\sqrt{\frac{25}{64}}

The square root can be applied to numerator and denominator separately

=\frac{\sqrt{25}}{\sqrt{64}}

Factorization

=\frac{\sqrt{5*5}}{\sqrt{2*2*2*2*2*2}}\\=\frac{\sqrt{5^2}}{\sqrt{2^2*2^2*2^2}}\\=\frac{5}{2*2*2}\\=\frac{5}{8}

Hence,

Option A. 5/8 is the correct answer.

MA_775_DIABLO [31]
Cosα=x/L

x=Lcosα, we are told the ladder is 10ft and α=42.5 so

x=10cos42.5° ft

x≈7.37 ft (to nearest hundredth of a foot)

Determine if the three given side<br> lengths form a right triangle.<br> 10 cm, 15 cm, 20 cm
antiseptic1488 [7]

Answer:

It doesn't form a right triangle

Step-by-step explanation:

According to the Pythagorean theorem, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

a^2 + b^2 = c^2 by substituting the three values, 10, 15, and 20 you should get an equivalent value of the hypotenuse.

10^2 + 15^2 = 20^2

100 + 225 = 400

325 =/= 400

This is false.

Since this is not equivalent, it is NOT a right triangle.

Hope this helped :)

10+8c=42<br><br> a great question to be answered
ivanzaharov [21]
10 + 8c= 42
subtract 10 from both sides

8c= 32
divide both sides by 8

c= 4


CHECK
10 + 8(4)= 42
10 + 32= 42
42= 42


ANSWER: c= 4

Hope this helps! :)
