Answer:
1.5, -8, 0, 2f, 2/3
Step-by-step explanation:
j(x) = 2x means the function name is j, and it is a function of the variable x. To evaluate the function, you put the given value everywhere you see x, and do the arithmetic.
j(0.75) = 2(0.75) = 1.5
j(-4) = 2(-4) = -8
j(0) = 2(0) = 0
j(f) = 2f
j(1/3) = 2(1/3) = 2/3

Find the distance between A(2,5) and B(-2,9)
Answers
Answer:
The answer is
[tex]4 \sqrt{2} \: \: or \: \: 5.656 \: \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A(2,5) and B(-2,9)
The distance between them is
[tex] |AB| = \sqrt{ ({2 + 2})^{2} + ({5 - 9})^{2} } \\ = \sqrt{ {4}^{2} + ({ - 4})^{2} } \\ = \sqrt{16 + 16} \\ = \sqrt{32} \\ [/tex]We have the final answer as

Answers
Answer:
Points N and K are on plane A and plane S.
Point P is the intersection of line n and line g.
Points M, P, and Q are noncollinear.
e2020
Step-by-step explanation:
According to the given diagram of Intersecting planes, Option (1), Option (3), Option (4) are True.
What are planes?A plane is a two-dimensional, flat surface that stretches indefinitely.
When does a point lie on a plane?A point is said to lie on a plane when it satisfies the equation of plane which is ax^3 + bx^2 + cx+ d = 0 and sometimes it is just visible in the figure whether a point is lying on a plane or not.
In Option(1) : Points N and K are lying on the line of intersection of plane A and S and will satisfy the equation of both planes.
In Option(2) : Point P is lying on both planes B and S, but the point M is lying only on plane B, hence this option is wrong.
In Option(3) : It is clearly visible the Point P is the point of intersection of lines n and g.
In Option(4) : It is clearly visible that Points M,P,Q are not lying on the same line, hence they are non-collinear.
In Option(5) : Line d intersects the plane A at point L and not point N, hence this is also wrong.
Hence the correct options are 1,3,4.

2x² + 9x + 9
Step-by-step explanation:
To evaluate f(x + 3) substitute x = x + 3 into f(x), that is
f(x + 3) = 2(x + 3)² - 3(x + 3) ← expand (x + 3)² using FOIL
= 2(x² + 6x + 9) - 3(x + 3) ← distribute both parenthesis

A. Parallel rays
B. Perpendicular rays
C. Skew rays
D. Intersecting rays
Answers
Answer:
B. Perpendicular rays
Step-by-step explanation:
Definition Perpendicular: Perpendicular lines, rays, or segments intersect at right angles. If lines, rays, or segments are perpendicular, then they are right angles. If lines, rays, or segments intersect. at right angles, then they are. perpendicular.
Hope this Helps
The rays that intersect at a right angle are perpendicular rays option (B) is correct.
What is a perpendicular line?Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines.
As we know,
From the definition, the perpendicular lines are the lines that intersect at right-angle or 90 degrees.
Two rays that intersect at a right angle are perpendicular rays.
Thus, the rays that intersect at a right angle are perpendicular rays option (B) is correct.

AYUDAA es para hoyyy Un avión volaba a 14.800 metros de altura . Primero , bajo a 23.000 decímetros y luego 54 hectometros más a qué altura en kilómetros vuela ahora ? EN ESPAÑOL LA RESPUESTA POR FAVOR Gracias
Answers
Answer:
7.1 km or 7.1 kilometer
Step-by-step explanation:
Esta pregunta se resuelve mediante la conversión de unidades SI. Nuestra respuesta final será en kilómetros, por lo tanto, estamos convirtiendo todos los valores dados a kilómetros.
De la pregunta, tenemos la siguiente información:
Altura de vuelo actual del avión = 14.800 metros
1 metro = 0.001 kilómetro
14,800 metros =
14,800 × 0.001
= 14.8 kilómetros
Avión que descendió primero = 23.000 decímetros
1 decímetro = 0.0001 kilómetro
23,000 decímetros =
23,000 × 0.0001 kilómetro
= 2.3 kilómetros
Descendió la segunda vez = 54 hectómetros más
1 hectómetro = 0.1 kilómetro
54 hectómetros =
54 × 0.1 kilómetro
= 5.4 kilómetros
Por lo tanto, la altura en kilómetros que vuela el avión ahora se calcula como
14.8 km - 2.3 km - 5.4 km
= 14.8 km - (2.3 km + 5.4 km)
= 14.8 kilometros - 7.7 kilometros
= 7.1 kilometros
Por lo tanto, el avión vuela actualmente a 7.1 km o 7.1 kilómetros.

Step-by-step explanation:
A difference of squares is factored in general as
a² - b² = (a - b)(a + b)
(i)
(x + 5)² - 16 ← is a difference of squares, that is
(x + 5)² - 4²
= (x + 5 - 4)(x + 5 + 4)
= (x + 1)(x + 9)
(j)
(x - 4)² - 9 ← is a difference of squares, that is
(x - 4)² - 3²
= (x - 4 - 3)(x - 4 + 3)
= (x - 7)(x - 1)
(n)
(2y + 7)² - y² ← is a difference of squares
= (2y + 7 - y)(2y + 7 + y)
=(y + 7)(3y + 7)

Point O is on line segment NP. Given N P = 4x + 10, NO = 4x, and
OP = x + 5, determine the numerical length of NP.
Answers
Answer:
30
Step-by-step explanation:
Hope this will help:)
The numerical length of line segment NP will be 30 units.
What is a line segment?A line segment in mathematics has two different points on it that define its boundaries.
A line segment is sometimes referred to as a section of a path that joins two places.
Point O is on line segment NP.
Given NP = 4x + 10, NO = 4x, and OP = x + 5.
We know that for a line segment.
PN = PO + ON
4x + 10 = 4x + x + 5
x = 5
Then the numerical length of line segment NP will be
NP = 4x + 10
NP = 4(5) + 10
NP = 20 + 10
NP = 30
Then the numerical length of line segment NP will be 30 units.

Answers
Answer:

Step-by-step explanation:
0.48 is read as "forty-eight hundredths," so we can write it as a fraction as
48/100.
Since both 48 and 100 have a common factor, we can reduce the fraction.
48 and 100 are both divisible by 4.
48/100 = 12/25
There are no common factors of 12 and 25, so 12/25 is the answer.
