Answer: The vertex of the graph of y = x^2 is shifted to the right 4 units and up 3 units

Step-by-step explanation:

Option (D) the vertex of the graph of y = x^2 is shifted to the right 4 units and up 3 units is the correct answer.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The graph of a function f is the set of all points in the plane of the form (x, f(x)).

For the given situation,

The function y = (x - 4^)2 + 3

Plot the graph on substituting the function [tex]y=x^{2}[/tex] as shown in the graph below.

On comparing the two functions, the transformation of the vertex of the graph of y = x^2 is shifted to the right 4 units and up 3 units.

Thus the function y = (x - 4)^2 + 3 is a transformation of the function         y = x^2.

Hence we can conclude that option (D) the vertex of the graph of y = x^2 is shifted to the right 4 units and up 3 units is the correct answer.

Answer:  

Equation translates to 289 + y = 206

it solves to y = -83

====================================================

Explanation:

The "and y more" means we are adding y onto 289 to get the expression 289+y. This is set equal to 206 because of the term "is" in the original statement.

Therefore, "289 and y more is 206" translates fully to the equation 289+y = 206

This is the same as saying y+289 = 206

To isolate y, we undo what is happening to it. We are adding 289 to it, so we must subtract 289 from both sides

y+289 = 206

y+289-289 = 206-289

y = -83

So we are adding -83 to 289 to get 206

Since Dylan noted the time of day and the temperature, in degrees Fahrenheit, and his findings are as follows: At 6 am, the temperature was 56 ° F, for the next 2 hours, the temperature rose 3 ° per hour, for the next 3 hours, it rose 4º per hour, and the temperature then stayed steady until 6 pm, while for the next 4 hours, the temperature dropped 3 ° per hour, and the temperature then dropped steadily until the temperature was 61 ° at midnight , to determine the average temperatures, the following tables must be made:

6 AM = 56

7 AM = 59

8 AM = 62

9 AM = 66

10 AM = 70

11 AM = 74

6 PM = 74

Answer:

6 hours before lunch

Step-by-step explanation:

Let x = hours before lunch

after lunch = 1/3x

Total time worked = 8 hours

x+1/3 x = 8

Combine like terms

4/3x = 8

Multiply each side by 3/4

3/4 * 4/3x = 8 * 3/4

x = 6

6 hours before lunch

Answer:

The carpenter worked 3x, or 6 hrs, before lunch.

Step-by-step explanation:

Represent the time worked before lunch as 3x and the time worked after lunch as x.  Then 3x + x = 8 hrs, and so:

4x = 8 hrs, and

x = 2 hrs

The carpenter worked 3x, or 6 hrs, before lunch.

Answer:

a + 8

Step-by-step explanation:

Note that

(x + y)² = x² + 2xy + y²

           = x² + y² + 2xy

           = a + 2(4) = a + 8

Here, we are required to determine an expression equal to (x + y)²

The correct answer is therefore (a + 8)

First, x² + y² = a can be rewritten completing the square method as;

(x+y) (x+y) = a + 2xy

when we expand the expression above; we have;

x² + 2xy + y² = a + 2xy

since, 2xy is present on both sides of the equation;

we still get the expression; x² + y² = a

Therefore, (x+y)² = a + 2xy

we can then substitute the value 4 for xy in the equation above;

Thus, since xy = 4, therefore 2xy = 8

Consequently, (x+y)² = a + 8

The correct answer is therefore (a + 8)

Answer:

x ≥ −5 and x < 4

Step-by-step explanation:

-4x + 1 ≤ 21 and 5x + 2 <  22

5x + 2 < 22 = x < 4

We can plug it in: 5 x 3 + 2 < 22 = 17 < 22

-4x + 1 ≤ 21 = x= -5 and lower

Plug it in: -4 x -5 + 1 ≤ 21 = 21 ≤ 21 = x ≥−5

So both answers would be:

x ≥−5 for -4x + 1 ≥ 21

x < 4 for 5x + 2 <  22

Answer:

B. x = 7/2 or x=-1/3

Step-by-step explanation:

You know both angles 6x² and 19x+7 have to be the same, so you can solve

6x² = 19x+7

6x² - 19x - 7 = 0

apply the quadratic formula and find

x = -1/3 or x = 7/2

now think carefully if the negative x is a realistic solution. It would lead to the angles being (2/3)°. This is not what the picture suggests, but it is also not wrong, so answer B seems the best.

Answer:

112.5:15=7.5

Step-by-step explanation:

112.5:15

=112.5÷15

=7.5

The equation "112.5 : 15 = 7.5" is true.

Proceed option 1:

"15 - 112.5 = 7.5":

This equation is not correct because 15 - 112.5 does not equal 7.5.

Proceed option 2:

"15 : 112.5 = 75":

This equation is not correct because when we divide 15 by 112.5, we get a decimal answer of 0.1333, not 75.

Proceed option 3:

"112.5 : 15 = 7.5": This equation is correct.

When we divide 112.5 by 15, we get an answer of 7.5.

Proceed option 4:

"112.5 : 15 = 75": This equation is not correct because when we divide 112.5 by 15, we get an answer of 7.5, not 75.

Hence equation "112.5 : 15 = 7.5" is correct.

Answer:

(i) F = 25 N

(ii) F = 35.36 N

(iii) F = 43.3 N

Step-by-step explanation:

We note that the component of force acting along the incline surface is given by the relation

Force, acting parallel to the incline plane, [tex]F_p[/tex] = M×g×sin(θ)

Given that the weight of the body is given as 50 N, we have;

M×g = 50 N

Therefore we have;

(i) For the plane with angle of elevation = 30°

[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(30°) = 25 N

The force  [tex]F_p[/tex]  = F = 25 N

F = 25 N

(ii) For the plane with angle of elevation = 45°

[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(45°) = 50 × (√2)/2 = 25·√2 N

[tex]F_p[/tex] = F = 25×√2 N = 35.36 N

F = 35.36 N

(iii) For the plane with angle of elevation = 60°

[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(60°) = 50 × (√3)/2 = 25·√3 N

[tex]F_p[/tex] = F = 25×√3 N = 43.3 N

F = 43.3 N.

==============================================

Explanation:

The chords intersect to form the angle 73 degrees. The chords also form the arcs of 96 and x. Averaging the arc measures will result in the internal angle 73

---------

(x+96)/2 = 73

x+96 = 2*73 ... multiply both sides by 2

x+96 = 146

x = 146-96 ... subtract 96 from both sides

x = 50

Answer:

y = 0

Step-by-step explanation:

Given

f(x) = 4x² +x⁵ +10x³ +5x+8x⁴

Required

Determine the y intercept

The y intercept of a function is a point where x = 0

So, we have to substitute 0 for x in the above function

f(x) = 4x² +x⁵ +10x³ +5x+8x⁴ becomes

f(0) = 4(0)² +(0)⁵ +10(0)³ +5(0)+8(0)⁴

f(0) = 4 * 0 + 0 + 10 * 0 + 5 * 0 + 8 * 0

f(0) = 0 + 0 + 0 + 0 + 0

f(0) = 0

Substitute y for f(0)

y = 0

Hence, the y intercept is 0

Lines m and n are perpendicular

Step-by-step explanation:

Where two lines l an m are said to be perpendicular to a given line n, then we have;

1) When  l and m are in different planes,

a) l and m can be parallel lines to each other or

b) l and m can be perpendicular to each other or

c) l and m can be at an angle x, to each other

2) When l and m intersect with the line n at a point p, then, we have;

l and m must be in the same plane with each other.

Answer:

Step-by-step explanation:

f(0) = 8       {y-axis intercept = (0, 8)}

Vertex = (1, 9)

f(x) = a(x - 1)² + 9

8 = a(0-1)² + 9

8 = a + 9

a = -1

f(x) = - (x - 1)² + 9

f(x) = - (x² - 2x + 1) + 9

f(x) = - x² + 2x - 1 + 9

f(x) = - x² + 2x + 8

x₁ = -2  and x₂ = 4, so also:

f(x) = -(x + 2)(x - 4)

Answer:

g(x) = -1 (x + 2)(x − 4)

Step-by-step explanation:

To write the equation of the function in factored form, g(x) = a(x − r1)(x − r2), find the values of r1, r2, and a.

The function has x-intercepts of -2 and 4, so (x − (-2)), or (x + 2), and (x − 4) are factors of the equation.

To find a, look at how the value of y changes for 1 unit to the right of the vertex. The y-value goes down 1 unit for a point 1 unit to the right of the vertex, so a = -1.

The equation of this quadratic function is g(x) = -(x + 2)(x − 4).

Hello!

First, we find out how much you spend a week.

Since you buy a $5 coffee 5 days a week we multiply the price for a coffee by 5.

5 * 5 = 25.

Next, we find out how much you spend a year.

Since you do it 50 weeks a year we multiply the amount you spend a week by 50

25 * 50 = 1250

Then, we find out how much you spend in 5 years.

We multiply the cost a year by the amount of years

1250 * 5 = 6250
