which expression is equivalent to sin(0.6x) - sin(0.4x)?

Answer:

ok

Step-by-step explanation:

is that you write down 1 and 10 then you write x10 to the power of a number

Answer:

1) x = 71

2) x = 117

5)

m<1: 35

m<2: 77

m<3: 52

m<4: 77

m<5: 65

m<6: 25

Step-by-step explanation:

1)

x + 41 + 68 = 180

x + 109 = 180

x = 71

2)

x + 47 + 16 = 180

x + 63 = 180

x = 117

3)

<2 + 103 = 180

<2 = 77

<1 + 68 + 77 = 180

<1 + 145 = 180

<1 = 35

<4 + 103 = 180

<4 = 77

<5 + 41 + 77 = 180

<5 + 115 = 180

<5 = 65

<6 + 65 = 90

<6 = 25

<3 + 103 + 25 = 180

<3 + 128 = 180

<3 = 52

B)  7 gallons

Step-by-step explanation:

car begins with 12 gallons and, at a rate of 29 mpg, would allow the car to travel for 348 miles

car only traveled 140 miles so 208 miles more can be driven

208÷29 is approx 7 gallons

Answer:

A) Ellipse with foci in the first and third quadrants.

Step-by-step explanation:

Answer:

b = 11.0

Step-by-step explanation:

From the given properties of the triangle,

b = AC

Applying the cosine rule, we have;

[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] - 2acCos B

   = [tex]10^{2}[/tex] + [tex]7^{2}[/tex] - 2(10 x 7) Cos 80

   = 100 + 49 - 140 x 0.17365

   = 149 - 24.311

   = 124.689

b = [tex]\sqrt{124.689}[/tex]

  = 11.1664

b = 11.0

Answer:

circumference:  12.56 yd

area:  3.14(2 yd)² = 12.56 yd²

Step-by-step explanation:

The circumference formula is C = 2πr (pi, not pie), where r is the radius.

When r = 2 yd and π ≈ 3.14, the circumference is:

C = 2(3.14)(2 yd) = 12.56 yd

Answer:

8 ft

Step-by-step explanation:

The area of a paralellagram is b*h. Since we know the base, 15, we can plug this into an equation.

15(h) = 120.

Divide by 15 on both sides to get you 8.

Fred's age is 82.

Amanda's age is 27.

Catherine's age is 14.

Blake's age is 12.

The equation that represents Fred's age is: 1 + 3x =

Where x is Amanda's age

Fred and Amanda's age : 109 = 1 + 3x + x

4x + 1 = 109

4x = 109 - 1

4x = 108

x = 108 / 4

x = 27

Fred's age = 1 + (3 x 27) = 82

The equation that represents Blake's age is: b =  2c - 16

Where: b = Blake's age

c = Catherine's age = 2 + b

b = 2(2 + b) - 16

b = 4 + 2b - 16

16 - 4 = 2b - b

12 = b

Catherine's age = 12 + 2 = 14

Answer:

the angle is 245°

Step-by-step explanation:

that is a pentagon, (a shape with 5 sides)

we know 4 of the angles in the pentagon

the sum of those 4 angles is

58°+100°+112°+25°=295°

to find a shapes total amount of °, the equation is (n-2)x180°

(5-2)x180°

=540°

540°-295°=245°

x=245°

Answer:

12 cubic inches

Step-by-step explanation:

volume of a cylinder= pi*r2*height

but we are given 36 as cylinder volume.

Therefore , 36 = pi*r2* height

r2*height = 36/pi, let call this equation 1

volume of a cone = pi*r2*height/3;

but from equation 1, r2*height =36/pi, substituting this value in volume of cone.

volume of cone= pi*(36/pi)/3 = 12 cubic inches

Answer:

4 8.95h + 10 < 115

Step-by-step explanation:

Answer: 4) 8.95h + 10 < 115

Step-by-step explanation:

We know the inequality will be equal to less than 115 since it states that the order was less than $115.

The equation would look like: some amount of shin guards times 8.95 each + $10 shipping = less than $115

8.95h + 10 < 115

(h in the given equation is the amount of shin guards)

Answer:

the expression above is

y = Subscribers after time t = S

a = Initial Subscribers =20,000

r = Growth rate = 0.08 = 8%

t = time in years = y

Step-by-step explanation:

A cable company uses the formula S = 20,000 (1 + 0.08)^y to estimate the number of subscribers, S, that use their service after y years. If there were 20,000 cable television subscribers when the cable company began, what is the meaning of the expression (1 + 0.008) ^y?

The above question represents Exponential growth

Exponential growth formula =

y = a( 1 + r) ^t

Where:

y = Population after time t

a = Initial Population

r = Growth rate

t = time in years

S = 20,000 (1 + 0.08)^y

Hence, the expression above is

y = Subscribers after time t = S

a = Initial Subscribers =20,000

r = Growth rate = 0.08 = 8%

t = time in years = y

[tex]arc\ MN + 150 = 180[/tex]

Step-by-step explanation:

Given

[tex]\angle NOP = 150^\circ[/tex]

See attachment for circle O

Required

Find [tex]arc\ MN[/tex]

The sum of angles in a semi-circle is 180 degrees.

So:

[tex]arc\ MN + \angle NOP = 180[/tex]

This gives:

[tex]arc\ MN + 150 = 180[/tex]

Hence, the equation is: [tex]arc\ MN + 150 = 180[/tex]

7-2=5

Therefore the distance between the two points is 5

Answer: 5

Step-by-step explanation:

D = √(x₂ - x₁)² + (y₂ - y₁)²

x₁ =2 y₁ =6 x₂ =7 y₂ =6

D =√(7-2)² +(6-6)²

D=√(5)² +(0)²

D =√25
