Answer:

a=1

Step-by-step explanation:

a+3=2a+2

Take away 3 from both sides

a=2a-1

Take away 2a from both sides

-a=-1

Multiply by -1

a=1

a + 3 = 2a + 2

move 2a to the other side

sign changes from +2a to -2a

a-2a+3= 2a-2a + 2

a-2a+3=2

-a+3=2

move 3 to the other side

-a+3-3= 2-3

-a= 2-3

-a= -1

mutiply both sides by -1 to get +a

(-1)(-a)=(-1)(-1)

Answer:

a= 1

If cos(x) = 0.5, then what is x?
Anestetic [448]

Answer:

=60 the second option.

Step-by-step explanation:

Given the trigonometric ratio, we can find the value of the angle by simply finding the inverse of the given ratio.

If for example Cos ∅= a, then ∅=Cos⁻¹a

If Cos (x)= 0.5, then x= Cos⁻¹ 0.5

Cos⁻1 0.5=60°

The angle whose sine is 0.5 is ∅=60°

Jacqueline is checking her bicycle’s wheel. The wheel has a radius of 20 cm, and its center is 51 cm above the ground. Jacquelin
Alex777 [14]

Answer:

h = 36.9 cm

Step-by-step explanation:

The function given to us is:

h(t) = 51 + 20 sin(225t)

Where h(t) is the function of the height in centimeters while t represents the time in seconds.

We have to find the height h(t) when the time is equal to 19 seconds.

Substitute t=19 into the given function

h(19) = 51 + 20 sin(225(19))

h(19) = 51 + 20 sin(4275)

h(19) = 51 + 20 (-0.7071)

h(19) = 51 + (-14,1421)

h(19) = 36.8579 cm

Rounding off to nearest 10th

h = 36.9 cm
