Step-by-step explanation:

which point is closer to the x-axis (0.7, 21) or (0.77, 10)

Answers

Answer:

[tex]d_A=21[/tex][tex]d_B=10[/tex]

Therefore, point B is closer to the x-axis.

Please check the attached graph.

Step-by-step explanation:

We know that:

x-coordinate of any point P(x, y) gives its distance of that point from the y-axisy-coordinate of any point P(x, y) gives its distance of that point from the x-axis

Given the points

(0.7, 21)(0.77, 10)

Let us say

A(0.7, 21)B(0.77, 10)

FOR POINT A(0, 7)

As the y-coordinate of point A(0.7, 21) ⇒ y = 21

We know that the y-coordinate of any point P(x, y) gives its distance of that point from the x-axis

Thus, the distance of point A(0.7, 21) from the y-axis is 21 units.

i.e.

[tex]d_A=21[/tex]

FOR POINT B(0.77, 10)

As the y-coordinate of point A(0.77, 10) ⇒ y = 10

We know that the y-coordinate of any point P(x, y) gives its distance of that point from the x-axis

Thus, the distance of point B(0, 7) from the y-axis is 10 units.

i.e.

[tex]d_B=10[/tex]

[tex]d_A=21[/tex][tex]d_B=10[/tex]

Therefore, point B is closer to the x-axis.

C. 1.5sin4x

please help fast, will give brainliest

Answers

Answer:

1.5sin4x

Step-by-step explanation:

I just answered this question and got it right.

The function is 1.5sin(4x).

What is sin function?

The ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle is the sine function in trigonometry. A right triangle's sides or unknown angles can be found using the sine function.

Given the sine function from (0, 2π), and amplitude is 1.5, the period is π/2

sine function in general form

y = a sin (b (x – h)) + d

where a = amplitude, b= period

h is the phase shift, and

d is the vertical displacement.

according to question, This function currently has no phase shift, since

h = 0, and no vertical displacement, since d = 0

equation is y = a sin b x

and b is ratio of normal period to desired period

b = 2π/(π/2)

b = 4

substitute the value of a and b in equation we get,

y = 1.5 sin (4x)

Hence the sin function from 0 to 2pi is y = 1.5 sin (4x).

What is the product of two fractions?

The product of two fractions is the product of the numerators and the product of the denominators.

Product of two fractions = Product of their denominators / Product of their numerators.

Twenty hundredths = 20/100

Sixty-five thousandths = 65/1000

Product = 20/100 × 65/1000

= 2/10 × 65/1000

= 130/10000

= 13/1000

= 0.013

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

(i)

Here A = 48, b = AB and h = DE = 6 , then

AB × 6 = 48 ( divide both sides by 6 )

AB = 8 cm

(ii)

Here A = 252, b = PQ = 9 and h = RT , then

9 × RT = 252 ( divide both sides by 9 )

RT = 28 cm
