Find the area enclosed by x2=2y and y2=16x​
jekas [21]

Answer: \dfrac{32}{3}

Step-by-step explanation:

Given

The parabolas are x^2=2y and y^2=16x

Find the point of intersection of two parabolas

\Rightarrow \left(\dfrac{x^2}{2}\right)^2=16x\\\\\Rightarrow x^4=64x\\\Rightarrow x(x^3-64)=0\\\Rightarrow x=0,4

Obtain y using x

(x,y)\rightarrow (0,0)\ \text{and }(4,8)

Area enclosed between the two is

\Rightarrow I=\int\limits^4_0 ({4\sqrt{x}-\dfrac{x^2}{2}}) \, dx\\\\\Rightarrow I=\left ( 4\times \dfrac{2}{3}x^{\frac{3}{2}}-\dfrac{x^3}{2\times 3} \right) _0^4\\\\\Rightarrow I=\left ( \dfrac{8}{3}\times 8-\dfrac{4^3}{6} \right )-0\\\\\Rightarrow I=\dfrac{128-64}{6}\\\\\Rightarrow I=\dfrac{64}{6}\\\\\Rightarrow I=\dfrac{32}{3}

Thus, the area bounded by the two parabolas is  \dfrac{32}{3} sq. units.

The hypotenuse of a 45°-45°-90° triangle measures 4 cm. What is the length of one leg of the triangle? 2 cm 2 StartRoot 2 EndRoo
Oxana [17]

Answer:

2\sqrt{2} cm

Step-by-step explanation:

In order to solve this you just have to remember the formula for the sides and hypotenuse of the triangle rectangle:

c^{2} =a^{2} +b^{2}

Since A and B are equal we will use X to represent them both:

c^{2} =a^{2} +b^{2}\\4^{2} =x^{2} +x^{2}\\16 =2x^{2}\\8=x^{2} \\x=\sqrt{8}=\sqrt{4*2}=2\sqrt{2}

ANd by solving the equation we get that the length of the legs of the triangle rectangle with a hypotenuse of 4cm is 2\sqrt{2} cm

Write the product using exponents -3/7×3/7×3/7<br>​
zlopas [31]

Answer:

-(\frac{3}{7})^3

Step-by-step explanation:

Since we see that 3/7 is multiplied by itself three times, we can use exponents as a shorter way to write this. The expontent tells us how many times the base number, 3/7, is multiplied by itself.

-1 * (\frac{3}{7})^3= -1 * \frac{3}{7} *  \frac{3}{7} * \frac{3}{7}

We then multiply by -1 to (3/7)^3 to get the exact answer.

-(\frac{3}{7})^3
