Answer:
8 cm and 28 cm
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

Which of the following is the function rule for the graph of the sin function from 0 to 2pi if the amplitude is 1.5 and the period is (pi/2)?
A. 1.5sin(pi /4)x
B. 1.5sin2x
C. 1.5sin4x
please help fast, will give brainliest
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).

A poster of the detroit lions football players uses a scale of 4 inches= 3 feet. If quarterback Matthew stafford is 8 1/2 inches tall on the poster, find his actual height.
Answer:
The actual height = 6.38 feet
Step-by-step explanation:
Given that a poster of the detroit lions football players uses a scale
of 4 inches = 3 feet
so
1 inch = 3/4 feetGiven that the poster's length:
[tex]8\frac{1}{2}=\frac{17}{2}=8.5[/tex] inch
We need to determine the actual height if quarterback Matthew Stafford is 8 1/2 inches tall on the poster.As 1 inch = 3/4 feetThus, we need to multiply 8.5 inches by 3/4 to determine the actual height of the player.
Actual height = 8.5 × 3/4 feet
= 6.38 feet
Therefore, the actual height = 6.38 feet

a number is 2/3 of another number. if the sum of the two numbers is 30, find the smaller number.
Answer: The numbers are 4 and 6.
Step-by-step explanation:
Let one number be represented as
x
and the other as
y
.
According to the problem:
x
=
2
3
y
and
x
+
y
=
10
From the second equation we get:
x
+
y
=
10
∴
y
=
10
−
x
(subtracting
x
from both sides)
Replacing the value of
y
in the first equation we get:
x
=
2
3
y
x
=
2
3
(
10
−
x
)
Multiplying both sides by
3
we get:
3
x
=
2
(
10
−
x
)
Opening the brackets and simplifying we get:
3
x
=
20
−
2
x
Add
2
x
to both sides.
5
x
=
20
Divide both sides by
5
.
x
=
4
Since from the second equation we have:
x
+
y
=
10
substituting
x
with
4
we get:
4
+
y
=
10
Subtract
4
from both sides.
y
=
6

which point is closer to the x-axis (0.7, 21) or (0.77, 10)
Answer:
As
[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-axisGiven 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 = 21We 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 = 10We 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]
As
[tex]d_A=21[/tex][tex]d_B=10[/tex]Therefore, point B is closer to the x-axis.
