Answer: $A=\frac{14}{9}\cdot \sqrt{2}\ unit^2$

Step-by-step explanation:

Given

Two curves are given

$y=10 x^2$

and $y=x^2+2$

the two curves intersect at

$10x^2=x^2+2$

$x=\pm \frac{\sqrt{2}}{3}$

to get the we need to integrate the curves over x axis

$A=\int_{-\frac{\sqrt{2}}{3}}^{\frac{\sqrt{2}}{3}}\left ( x^2+3-10x^2\right )dx$

$A=2\int_{0}^{\frac{\sqrt{2}}{3}}\left ( 3-9x^2\right )dx$

$A=2\left [ 3\left ( \frac{\sqrt{2}}{3}\right )-\frac{9}{3}\left ( \frac{\sqrt{2}}{3}\right )^3\right ]$

$A=2\sqrt{2}\left [ 1-\frac{2}{9}\right ]$

$A=\frac{14}{9}\cdot \sqrt{2}\ unit^2$

TIMED!!!

Answer: Last option.

Step-by-step explanation:

The total amount of concrete in the ramp ( $V_t$ ) will be the sum of the volume of the rectangular prism ( $V_{rp}$ ) and the volume of the triangular prism ( $V_{tp}$ )

$V_t=V_{rp}+V_{tp}$

The formulas are:

$V_{rp}=lwh$

Where "l" is the lenght, "w" is the width and "h" is the height.

$V_{tp}=\frac{bhl}{2}$

Where "l" is the lenght, "b" is the base and "h" is the height.

Substituting, we get:

$V_t=V_{rp}+V_{tp}\\\\V_t=lwh+\frac{bhl}{2}\\\\V_t=(18in)(6in)(6in)+\frac{(8in)(6in)(18in)}{2}\\\\V_t=1,080in^3$

Can someone please help

Alika [10]

Answer:

option (B).

Step-by-step explanation:

it's really simple....

just replace the (n) near the 3 with 1,2,3,4,5 and 6 and then solve the maths and when you're done , you add the answers all up.

sooo...

3(1)-2 = 1

3(2)-2 = 4

3(3)-2 = 7

3(4)-2 = 10

3(5)-2 = 13

3(6)-2 = 16

now we add them all up...

1+4+7+10+13+16 = 51.

Hope this helps.

Good luck.
