Answer:

112

Step-by-step explanation:

Answer:

112

Step-by-step explanation:

4×4= 16×2=32

5×4= 20×2=40

5×4= 20×2=40

Total = 112

In Unit Circle, we know that x-term = cos and y-term = sin

[tex] \large \boxed{(x,y) = (cos \theta , sin \theta)}[/tex]

Recall the cotangent ratio:

[tex] \large \boxed{cot \theta = \frac{cos \theta}{sin \theta} }[/tex]

Because cotangent is reciprocal of tangent which is sin/tan so cotangent is 1/(sin/cos) = cos/sin.

Substitute the point in.

[tex] \large{cot \theta = \frac{ - 5}{ - 12 } \longrightarrow \frac{5}{12} }[/tex]

Answer:

Step-by-step explanation:

The general equation of the circle is:

(x-h)²+(y-k)²=r²

(h, k)=(-3,-5)  are the coordinates of the center of the circle.

r=6  is the radius

The equation of the circle is:

(x+3)²+(y+5)² = 36

Answer:

  354,998

Step-by-step explanation:

If the number is less than 350,000, it will not round to 400,000.

If the number is 355,000 or more, it will not round to 350,000.

The number (n) must satisfy ...

  350,000 ≤ n < 355,000

__

If we're restricted to integers, the number could be any between 350,000 and 354,999, inclusive. One possibility is 354,998.

Answer:

A pair of angles whose sum is not 90 or 180 is not an angle pair.

a) From the left, the limit is 1, since

[tex]\displaystyle\lim_{x\to1^-}f(x)=\lim_{x\to1}x=1[/tex]

b) From the right, it's 2, since

[tex]\displaystyle\lim_{x\to1^+}f(x)=\lim_{x\to1}2=2[/tex]

c) Also 2, same reasoning as in (b).

d) 1, since

[tex]\displaystyle\lim_{x\to4^+}f(x)=\lim_{x\to4}(5-x)=1[/tex]

e) No, neither two-sided limits exist because the respective one-sided limits do not agree.

Answer

c,116°

Step-by-step explanation:

i don't know how to draw a diagram?

Join ends of chord with the center making angles ∠2,∠3 and angle at the center.

angle at the center=128°

∠1=∠2+90°

∠2=∠3

∠2+∠3+128=180

∠2+∠2+128=180

2∠2=180-128=52

∠2=52/2=26

∠1=26+90=116°

sorry i can't explain properly without picure.

Answer:

4096 different cakes can be made if flavors can be repeated.

Step-by-step explanation:

Since at Misu's Ice Cream Parlor, their famous 4-layer ice cream cake consists of four layers of ice cream alternating with layers of cake, if there are 8 flavors of ice cream, and we count different cakes based on the order of ice cream Layers from top to bottom, to determine how many different cakes can be made if flavors can be repeated, the following calculation must be performed:

8 x 8 x 8 x 8 = X

64 x 64 = X

4.096 = X

Therefore, 4096 different cakes can be made if flavors can be repeated.

Answer:

  25 +0i

Step-by-step explanation:

The conjugate of a complex number is that number with the sign of the imaginary part reversed.

For z = -3+4i, its conjugate z* is -3-4i. The product of z and z* is ...

  (-3 +4i)(-3 -4i) = -3(-3 -4i) +4i(-3 -4i)

  = 9 +12i -12i -16i² = 9 +16 = 25

The real part of the product is 25; the imaginary part is 0.

  (-3 +4i)(-3 -4i) = 25 +0i

_____

You may have noticed that (z)(z*) = |z|², the sum of the squares of the real and imaginary parts. It is always a non-negative real number.

Answer:

The relationship between the cost/mass is $2.25/kg.

Step-by-step explanation:

You first need to divide $4.50 / 2, to know what a single kilogram mass costs.

$4.50 / 2 = $2.25

Now that you have this unit rate $2.25, You can multiply/add it.

$4.50 + $2.25 is $6.75, + another $2.25 = $9.00, and so on.

Answer:

I think you would have to plug in 4 as X so it would be 4^2 +8(4)+ 7

that would be 16+ 32 +7 and that would equal 55

Answer: -4...?

Step-by-step explanation:

Step-by-step explanation:

[tex] \cos \theta = \frac{1}{ \sec\theta } = - \frac{3}{ \sqrt{30} } = - \frac{3 \sqrt{30} }{30} = - \frac{ \sqrt{30} }{10} [/tex]

[tex] \cos( \frac{\pi}{2} - \theta )= \cos \frac{\pi}{2} \cos \theta + \sin \frac{\pi}{2} \sin \theta [/tex]

Note that

[tex] \sin( - \theta) = - \sin \theta[/tex]

[tex] \cos \frac{\pi}{2} = 0 \: \: \: \: \: \sin \frac{\pi}{2} = 1[/tex]

Therefore,

[tex] \cos( \frac{\pi}{2} - \theta ) = 0.97[/tex]
