Answer:

  (c)  162 cm

Step-by-step explanation:

The centroid divides a median into parts with the ratio 1:2, so RL:LD = 1:2. Then RL:RD = 1:(1+2), and RD = 3RL.

  RD = 3·54 cm

  RD = 162 cm

Step-by-step explanation:

2x + y = 8 is the equation of a straight line. ... By substituting y = 0 into the equation we will find the corresponding x-coordinate at this point. y = 0 : 2x = 8 and so x = 4 hence point (4 , 0 ) on the x-axis

Answer:

20 pictures.

Step-by-step explanation:

In this question, we need to find out how many pictures Milan printed.

We know that the film processing costed $4.95 and each picture that was printed costed $0.35.

Lets turn this into an equation with x representing the amount of pictures:

y = 0.35x+ 4.95

Now we need to solve the equation. We can do this by plugging in our known cost, 11.95, into "y".

Solve:

11.95 = 0.35x + 4.95

Subtract 4.95 from both sides.

7 = 0.35x

Divide both sides by 0.35

20 = x

Milan printed 20 pictures.

Answer:

[tex]3x + 2y - 1 = 0 \\ 2y = - 3x + 1 \\ y = - \frac{3}{2} x + \frac{1}{2} \\ from \: general \: equation \: \: y = mx + c \\ by \: comparison \\ m = - \frac{3}{2} \\ c = \frac{1}{2} [/tex]

The value of the slope (m) will be -3/2. And the value of the y-intercept (c) will be 1/2.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The equation in the standard form is given below.

3x + 2y - 1 = 0

Separate 'y', then we have

3x + 2y - 1 = 0

2y = -3x + 1

y = -(3/2)x + 1/2

Compare the equation with the slope-intercept line.

m = - 3/2

c = 1/2

The value of the slope (m) will be -3/2. And the value of the y-intercept (c) will be 1/2.

                      -(-12x - 48)

                                  0 Remainder

so the answer is D  

The remainder of the polynomial P(x) = x³ - 28x - 48 will be 0. Then the correct option is D.

A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

The polynomial is given as,

P(x) = x³ - 28x - 48

Let's check if x + 4 = 0 is a factor or not. Then we have

x + 4 = 0

x = - 4

At x = -4, the value of the polynomial is given as,

P(x) = (-4)³ - 28(-4) - 48

P(x) = - 64 + 112 - 48

P(x) = - 112 + 112

P(x) = 0

The remainder of the polynomial P(x) = x³ - 28x - 48 will be 0. Then the correct option is D.

He does not have enough money

Step-by-step explanation:

Step one:

given data

The total money that Goerge has is $15

Expenses to incure

to see a movie ($9.00) and

to buy a pretzel ($2.65),

a drink ($1.35 ), and

two veggie cups ($1.74 each)= 1.74*2= $3.48

Totoal expenses= 9+2.65+1.35+3.48= $16.48

Step two:

The deficit that George will have is 16.48-15= $1.48

Hence he does not have enough money

Step-by-step explanation:

Answer:

We conclude that the graph y = x² can be transformed into the graph of the given equation y = (x - 12)²+3 by shifting the graph of y = x² right 12 units and then up 3 units.

Hence, option D is true.

Please check the attached graph.

Step-by-step explanation:

Given the parent function

y = x²

Given the transformed function

y = (x - 12)²

Horizontal Translation:

The horizontal translation of y = x² is of the form

f(x-h)

so y = y = (x - 12)² means y = x² is shifted 12 right.

Vertical Translation:

y = x²

Then y = x² + b is a vertical translation of y = x²

if b > 0, then y = x² + b is the graph of y = x² 'b' units up.

if b < 0, then y = x² + b is the graph of y = x² 'b' units down.

Thus, y = x² + 3 means the graph y = x²  is vertically shifted up by 2 units.

Please check the attached graph.

Therefore, the graph y = x² can be transformed into the graph of the given equation y = (x - 12)²+3 by shifting the graph of y = x² right 12 units and then up 3 units.

Hence, option D is true.

Answer:

Shift the graph of y = x2 right 12 units and then up 3 units.

Step-by-step explanation:

The triangle is an acute triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of angles of the triangle are

The measure of ∠ABC = 50°

The measure of ∠BAC = 50°

The measure of ∠ACB = 80°

So , all the angles of the triangle are less than 90°

So , it is an acute triangle

Hence , the triangle is acute
