Answer:

surface area: 456 cm²
volume: 408 cm³

Step-by-step explanation:

The surface area of the figure is the total of the areas of the two triangular bases and the three rectangular faces.

SA = 2(1/2)(8 cm)(6 cm) + (17 cm)(6 cm + 8 cm + 10 cm)

= 48 cm² + 408 cm²

SA = 456 cm²

The volume is the product of the area of the triangular base and the length of the prism.

V = (1/2)(8 cm)(6 cm)×(17 cm) = (24 cm²)(17 cm)

V = 408 cm³

Solve the system y=x²-2 and x²+y=4.Illustrate graphically.

lawyer [7]

Answer:

Solution: $(-\sqrt{3},1),(\sqrt{3},1)$

Step-by-step explanation:

System of equation:

$y=x^2-2\text{ and }x^2+y=4$

Using substitution method.

$y=x^2-2$ substitute into $x^2+y=4$

$x^2+x^2-2=4$ (combine like term)

$2x^2=4+2$ (Addition property of equality)

$2x^2=6$ (division property of equality)

$x^2=3$ (Taking square root)

$x=\pm \sqrt{3}$

Substitute x into $y=x^2-2$

$y=(\sqrt{3})^2-2$

$y=1$

Solution: $(-\sqrt{3},1),(\sqrt{3},1)$

Now cross check the solution using graph.

Find the surface area of the regular pyramid

love history [14]

Greetings from Brazil!

$4\dfrac{1}{2} =\dfrac{9}{2}$

$Af1=\dfrac{b\cdot h}{2} \cdot 4\\\\\\Af1=\dfrac{\dfrac{9}{2} \cdot 4}{2} \cdot 4\\\\\\Af1=\dfrac{\dfrac{36}{2} }{2} \cdot 4\\\\\\Af1=\dfrac{18}{2} \cdot 4\\\\Af1=9\cdot 4\\\\Af1=36~m^2$

$Af2=l^2\\\\Af2=(\dfrac{9}{2})^2\\\\\ Af2=\dfrac{81}{4}\\\\Af2=20,25~m^2$

$At=Af1+Af2\\At=36+20,25\\At=56,25~m^2$

I hope I helped you! =)
