Answer:

Step-by-step explanation:

The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph. The graph is also symmetric with a vertical line drawn through the vertex, called the axis of symmetry. These features are illustrated in (Figure).

The y-intercept is the point at which the parabola crosses the y-axis. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function, the values of x

Answer:

56 units, 84 units, 56 units, 140 units

Step-by-step explanation:

Since you have the ratios, you can multiply each by x, because you do not know the actual values.

2x+3x+2x+5x=336

12x=336

÷12  ÷12

x=28

Then, plug in the values of x.

So 2*28= 56

3*28=84

2*28=56

5*28=140

Answer:

The input is always represented on the x-axis.

The definition of a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

We cannot have multiple of the same inputs or x-values for a relation to be a function.

Answer:

{-1/2, -1/4, 1/2}

Step-by-step explanation:

x > - 1 can be voiced as "x is greater than -1."  In other words, any x value greater than -1 satisfies this inequality.

1/2 is greater than -1.  1/2 lies to the right of -1.

-1/2 is greater than -1.

-1/4 is greater than -1.

-5/2 is the same as -2 1/2.  This is smaller than -1.  Eliminate this choice

Answer:

The vertex of the parabola is;

([-1], [3])

Step-by-step explanation:

The given quadratic equation is presented as follows;

x² + 8·y + 2·x - 23 = 0

The equation of the parabola in vertex form is presented as follows;

y = a·(x - h)² + k

Where;

(h, k) = The vertex of the parabola

Therefore, we have;

x² + 8·y + 2·x - 23 = 0

8·y = -x² - 2·x + 23

y = 1/8·(-x² - 2·x + 23)

y = -1/8·(x² + 2·x - 23)

y = -1/8·(x² + 2·x + 1 - 23 - 1) = -1/8·(x² + 2·x + 1 - 24)

y =  -1/8·((x + 1)² - 24) =  -1/8·(x + 1)² + 3

Therefore, the equation of the parabola in vertex form is y =  -1/8·(x + 1)² + 3

Comparing with y = a·(x - h)² + k, we have;

a = -1/8, h = -1, and k = 3

Therefore, the vertex of the parabola, (h, k) = (-1, 3).

Answer:

y = -3/4x -4

Step-by-step explanation:

Parallel slope = -3/4

(-4,-1)

y - y1 = m(x - x1)

y + 1 = -3/4(x + 4)

y + 1 = -3/4x - 3

y = -3/4x -4

Answer:

y=-1.7x+8

Step-by-step explanation:

An equation of a line is y=mx+c

m is the gradient and c is the y intercept, which is where the line intercepts y.

you work out m getting two points and then subtracting y - y ÷ x - x

So in this graph, if we chose points (6,-2) and (3,3) then we would do this equation.

[tex] \frac{3 - - 2}{3 - 6} = \frac{5}{ - 3} = - 1.7[/tex]

So m = -1.7

c = 8 because it goes through 8 in y.

So the equation is y=-1.7x+8

Answer:

  h = 2m

Step-by-step explanation:

We can put the given values into the area formula and solve for the missing one.

  A = (1/2)(b1 +b2)h

  7m²= (1/2)(3m +4m)h

  7m² = (7/2)m·h

  (7m²)(2/(7m)) = h = 2m

The missing height is 2 m.

Answer:

24meters

Step-by-step explanation:

Given data

Joe walked 12m East

We are told that Joe continued to walk for another 12m east

Therefore, Joes displacement is

=12+12

=24m

His displacement is 24meters

The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.

The equation is  

d

=

12.5

×

t

Explanation:

To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:

For example

25

miles

÷

2

hours

=

12.5

miles

hour

A direct proportionality will always result in an equation that resembles this:

y

=

k

x

where  

y

and  

x

are the related quantities and  

k

is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. (And if the values given are real physical quantities, this constant will contain important information about the situation you are studying!)

There are 11 minutes more time to spend doing English homework.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

If you spent 58 minutes doing English homework and 47 minutes doing math homework.

Now,

Since, The time for doing English homework = 58 minutes

And, The time for doing Math homework = 47 minutes

So, The time more to spend doing English homework = 58 - 47

                                                                                   = 11 minutes

Thus, There are 11 minutes more time to spend doing English homework.

Answer:

BC/sin 23 = 10/sin 47

Step-by-step explanation:

Here, we want to select the true equation to find the length BC

From the question, we have the angle facing side BC; also, we have the angle and the side facing it for another side

In this situation, the best way to solve for BC is by the use of the sine rule

The sine rule states that the ratio of the length of a side and the sine of the angle facing the side is constant for a given triangle

Thus, we have it that;

BC/sin 23 = 10/sin 47
