Answer:

sin Ф.

Step-by-step explanation:

Cos (-270) = cos 90 = 0 and sin(-270) = sin 90 = 1.

So cos ( Ф - 270) =   cos Ф cos (-270) + sin Ф sin(-270)

=  cos Ф * 0 + sin Ф * 1

= sin Ф.

The absolute maximum of the function is 184 and the minimum value of the function is -72.

If the graph of an absolute value function opens downward, the y-value of the vertex is the maximum value of the function.

Given the function f(x) = x⁴-18x²+9 at the interval [-5, 5], the absolute maximum and minimum values at this endpoints are as calculated;

At end point x = -5

f(-5) = (-5)⁴-18(-5)²+9

f(-5) = 625-450+9

f(-5) = 184

At end point x = 5

f(5) = (5)⁴-18(5)²+9

f(5) = 625-450+9

f(5) = 184

To get the critical point, this point occurs at the turning point i.e at

dy/dx = 0

if y = x⁴-18x²+9

dy/dx = 4x³-36x = 0

4x³-36x = 0

4x (x²-9) = 0

4x = 0

x = 0

x²-9 = 0

x² = 9

x = ±3

Using the critical points [0, ±3]

when x = 0, f(0) =  0⁴-18(0)+9

f(0) = 9

Similarly when x = 3, f(±3)=  (±3)⁴-18(±3)²+9

f(±3) = 81-162+9

f(±3) = -72

It can be seen that the absolute minimum occurs at x= ±5 and the absolute minimum occurs at x =±3

absolute maximum = 184

absolute minimum = -72

Hence, the absolute maximum of the function is 184 and the minimum value of the function is -72.

Answer:

Step-by-step explanation:

ΔBOC is isosceles and M is the midpoint of BC

then

∠MOC = ∠BOM = 30°

then

∠BOC = 60°

……………………

OC // AB

then

∠ABO = ∠BOC = 60° (alternate-interior angles)

……………………………………………

In ΔOAB ,we have :

OA = OB and ∠ABO = 60°

Then ,

ΔOAB is an equilateral triangle.

then

∠AOB = 60°

……………………………

We get :

∠AOC = ∠AOB + ∠BOC = 60° + 60° = 120°

……………………………………………………

∠ADC = ∠AOC/2 = 120/2 = 60°

a = 9

Step-by-step explanation:

45 = 4(a + 3) – 3

Add 3 to both sides.

Divide both sides by 4.

12 = a + 3

Subtract 3 from both sides.

To get the slope you will need Rise over Run. 5/1 which is slope

which will make x=0 and y=4  which is y intercept.

The area of one petal of the polar curve r = 5 sin 2θ would be 25π/4.

Supposing that there is no direct formula available for deriving the area, we can derive the area of that region by dividing it into smaller pieces, whose area can be known directly.

Then summing all those pieces' area gives us the area of the main big region.

The polar curve r = 5sin 2θ

When r = 0, θ = 0, π/2 which corresponds to one loop.

We need the limits to provide r=0 or cos(5x) =0 so:

Therefore the area of the region enclosed by this curve is

[tex]A = \dfrac{1}{2} \int\limits^a_b {r^{2} } \, d\theta \\\\\\A = \dfrac{1}{2} \int\limits^{\pi /2}_0 {25sin^{2}2\theta } \, d\theta \\\\\\A = \dfrac{1}{2} \times 25\int\limits^{\pi /2}_0 {sin^{2}2\theta } \, d\theta \\\\\\A = \dfrac{1}{2} \times 25\int\limits^{\pi /2}_0 \dfrac {1-cos^{2}4\theta } {2}\, d\theta\\ \\\\A = \dfrac{25}{2}( \theta - \dfrac {sin4\theta} {2})\, d\theta |^{\pi /2}_0\\\\\\A = \dfrac{25}{2} \times \dfrac{\pi }{2} \\\\\\A = \dfrac{25\pi }{4}[/tex]

Thus, the area of one petal of the polar curve r = 5sin 2θ would be 25π/4.

Step-by-step explanation:

If there are 5 orange beads, and 3 purple beads, that means there is 8 beads that aren't pink in the bag.

If the rest are pink, and it's 3/5, that means 8 is 2/5. Divide by 2, and 4 is 1/5.

We can conclude that there are 12 pink beads, which is 3/5 of the total beads, by adding 2/5 and 1/5 (8 and 4)

The remaining 2/5 are the orange and purple beads.
