cant figure out what sin 40 - sin 20= ​

Answer:

How many feet does a car travel in 1 second if it is moving at a rate of 75 mph? So you're going 110 ft per second. In other words, the car travels 110 feet in 1 second (and does so each second assuming you maintain the speed of 75 mph).

The distance (in feet) travelled by the car moving at 75 mph in one second is 110 feet

Speed is the distance travelled per unit time. Mathematically, it can be expressed as:

Speed = distance / time

1 mph = 1.467 fps

Therefore,

75 mph = 75 × 1.467

75 mph = 110.025 fps

Distance = speed × time

Distance = 110.025 × 1

Distance ≈ 110 feet

Answer: [tex]x=n\pi +(-1)^n\dfrac{\pi}{6}[/tex], [tex]x=n\pi +(-1)^n\left(\dfrac{-\pi}{6}\right)[/tex]

Step-by-step explanation:

Given

[tex]\sin x-\sqrt{1-3\sin^2x}=0[/tex]

Take the square root term to the right-hand side

[tex]\Rightarrow \sin x=\sqrt{1-3\sin^2x}\\\text{Squaring both sides}\\\Rightarrow \sin^2x=1-3\sin^2x\\\Rightarrow 4\sin^2x=1\\\\\Rightarrow \sin^2x=\dfrac{1}{4}\\\\\Rightarrow \sin x=\pm\frac{1}{2}[/tex]

Answer:

8.8

Step-by-step explanation:

To find the hypotenuse...

a²+b²=c²

C is the hypotenuse, so we add the others...

8.4²+2.6²=c²

70.56+6.76=c

77.32=c

Now, square root c to bring it to its original position.

√77.32=8.8

Your answer is 8.8 yards.

-16 means where the line crosses y axis

Answer:

x = 73.3

y = 46.2

Step-by-step explanation:

Reference angle (θ) = 39°

Adjacent = 57

Hypotenuse = x

Opposite = y

Recall: SOHCAHTOA

✔️To find x, apply CAH:

Cos θ = Adjacent/Hypotenuse

Plug in the values

Cos 39° = 57/x

x × Cos 39° = 57

x = 57/Cos 39°

x = 73.3 (nearest tenth)

✔️To find x, apply TOA:

Tan θ = Opposite/Adjacent

Plug in the values

Tan 39° = y/57

57 × Tan 39° = y

y = 46.2 (nearest tenth)

Answer:

4th term = 0

6th term = -4

13th term = -18

Step-by-step explanation:

a(n) = 6 + -2(n-1)

a(4) = 6 + (-2)(3) which is 6-6

a(6) = 6 + (-2)(5) which is 6-10

a(13) = 6 + (-2)(12) which is 6-24

Answer:

  x = -6 or -4

Step-by-step explanation:

Maybe you want to know the x-intercepts. They are found by ...

  0 = (x +5)² -1 . . . . . divide by -4

  1 = (x +5)² . . . . . . . add 1

  ±√1 = x +5 . . . . . . square root

  -5 ± 1 = x . . . . . . subtract 5

  x = -6 or -4

The vertex is (-5, 4). The parabola opens downward, so the vertex is a maximum. The range of the function is (-∞, 4]. The vertical scale factor is -4, so the graph will appear narrower than that of the parent function.

Answer:

73.07%

Step-by-step explanation:

Given that,

Actual value of sold cookies = 26

Assumed value of sold cookies = 45

We need to find Gabby's percent error. The percentage error in a value is given by :

Error = ](Assumed value - Actual value)/Actual value]× 100

So,

[tex]\%=\dfrac{45-26}{26}\times 100\\\\=73.07\%[/tex]

So, Gabby's percent error is equal to 73.07%.

Answer: 73.1

Step-by-step explanation: Although the answer is 73.07 if you're in Acellus they want you to round to the nearest percent so the answer should be 73.1

Coordinates of center: (2,8)

Radius of circle: 3 units

Finding equation of the circle:

We know that the general form of a circle is:

(x-h)² + (y-k)² = (radius)²

where h is the x-coordinate of the center and k is the y-coordinate

replacing with the given values, we get:

(x-2)² + (y-8)² = (3)²
