When it says f(4) that means x=4

So you then just fill in all the x’s with 4’s and solve as normal

Answer:

The sin A expressed in ratio form is \frac{\sqrt{6} }{4}

Step-by-step explanation:

From the given right angled triangle diagram, sin A is calculated as follows;

sin \ A = \frac{Opp}{hypo} \\\\sin \ A = \frac{2\sqrt{6} }{8} \\\\sin \ A = \frac{\sqrt{6} }{4}

Therefore, the sin A expressed in ratio form is \frac{\sqrt{6} }{4}

Answer:

  D.  105 ft²

Step-by-step explanation:

The total surface area is the sum of the base area and the triangular face areas.

Area of base:

  A = s²

  A = (7 ft)² = 49 ft²

Area of 4 triangles:

  A = 4(1/2)bh

  A = 2(7 ft)(4 ft) = 56 ft²

Total surface area:

  base area + triangle area = 49 ft² +56 ft² = 105 ft²

What is the volume of the composite figure with the dimensions shown in the 3 views? (Round to the nearest tenth)
givi [52]

Answer:

278.9 units^3 to the nearest tenth.

Step-by-step explanation:

This is a cylinder on the bottom . resting on the cylinder is a prism.

Volume of the cylinder = π r^2 h  where r = 1/2 * 7 = 3.5 and h = 6.

V = π * 3.5^2 * 6 = 230.907 units^3.

Volume of the prism = l*w*h

= 4*4*3 = 48 units^3.

Volume of the composite figure = 230.907 + 48

= 278.9.
