Answer:

P = 64 cm

Step-by-step explanation:

<C = 150° - 90° = 60°

AB = AC

∠B = ∠C = 60°  } => ΔABC =  EQUILATERAL TRIANGLE =>

=> BC = 10 cm

P = 10cm + 8cm + 6cm + 10cm + 6cm + 6cm + 8cm + 10cm

P = 3x10cm + 2x8cm + 3x6cm

P = 30cm + 16cm + 18cm

P = 64 cm

3c/4 - 2c/4 = 4 (solve with work please)
xxMikexx [17]

Simplifying

2c + 3 = 3c + -4

Reorder the terms:

3 + 2c = 3c + -4

Reorder the terms:

3 + 2c = -4 + 3c

Solving

3 + 2c = -4 + 3c

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-3c' to each side of the equation.

3 + 2c + -3c = -4 + 3c + -3c

Combine like terms: 2c + -3c = -1c

3 + -1c = -4 + 3c + -3c

Combine like terms: 3c + -3c = 0

3 + -1c = -4 + 0

3 + -1c = -4

Add '-3' to each side of the equation.

3 + -3 + -1c = -4 + -3

Combine like terms: 3 + -3 = 0

0 + -1c = -4 + -3

-1c = -4 + -3

Combine like terms: -4 + -3 = -7

-1c = -7

Divide each side by '-1'.

c = 7

Simplifying

c = 7

Let f(x) = sin(x) + icos(x). Show that |f(x)| = 1.
Oksanka [162]
F(x) = sin(x) + icos(x)
|f(x)| = sqrt(sin^2(x) + cos^2(x)) = sqrt(1) = 1

Therefore, |f(x)| = 1

A farmer wants to build a new grain silo. The shape of the silo is to be a cylinder with a hemisphere on the top, where the radi
notsponge [240]

Answer:

The radius of the silo should be 16\ ft

Step-by-step explanation:

we know that

The volume of the grain silo is equal to the volume of the cylinder plus the volume of a hemisphere

V=\pi r^{2} h+\frac{4}{6}\pi r^{3}

we have

V=35,500\pi\ ft^{3}

h=4D=8r

substitute the values and solve for r

35,500\pi=\pi r^{2} (8r)+\frac{4}{6}\pi r^{3}

Simplify

35,500=r^{2} (8r)+\frac{4}{6}r^{3}

35,500=8r^{3}+\frac{2}{3}r^{3}

35,500=\frac{26}{3}r^{3}

r^{3}=35,500*(3)/26

r=16\ ft
