Step-by-step explanation:

By using cosine rules:

6/sin45° = b/sin90°

b = 6× sin45°/sin90°

b = 9.124(3d.p)

Also,

using Pythagoras theorm of right-triangle

b² = 6² + a²

9.124² = 6² + a²

83.247376 = 36 + a²

83.247376-36 = a²

47.247376 = a²

√47.247376 = a

6.874 = a

Write -2x^2 (-5x^2 + 4x^3) in standard form

saul85 [17]

-2x·-2x·(-5x·-5x+4x·4x·4x) Basically, you write out the number depending on the exponent. So if you have a power/exponent of 3, you write it out multiplied by itself 3 times. Hope this helps!

Circle the volume in cm^3 of a cylinder with the radius 5cm and height 8cm

Phantasy [73]

Answer:

<em>628 </em> $cm^{3}$

Step-by-step explanation:

Since the formula to find the volume of a cylinder is $\pi r^{2}$ h, we just need to fill things in.

Since the radius is 5 and the height is 8 and we know that pi=3.14, our new equation is:

3.14*5^2*8.

5*5=25. Now we simplify.

3.14 * 25 * 8

78.5 * 8

<em>628 </em> $cm^{3}$

Hope this helps!! <3 :)
