y = 2x^2

y = 3x^2 - 4

Graph the quadratic functions y =-2x^2 + 4 on a separate piece of paper. Using those graph, compare and contrast the shape and position of the graphs.​

Answers

Answer 1

Answer:

y = 2x^2 is a parabola opening up with it's vertex at (0,0)... y=3x^2 -4 is also a parabola opening up, but it is 'thinner' in that it rises in y faster and it's vertex is at (0,-4)

Step-by-step explanation:

all equations of the type y = ax^2 + b are parabolas centered on the y-axis, soo the vertex is always on (0,b)

If a is positive then the parabola opens up,

the bigger a is, the 'thinner' the graph is, i.e. the faster the graph rises

the value of b determines the location of the vertex, if b is added, then the vertex rises over the x-axis, if b is subtracted then the vertex is below the x-axis

week. At what week will Alyssa and Bill have the same amount of money?

Answers

Answer:

7  weeks

Step-by-step explanation:

Given data

Alyssa starts with $30 and saves $5 each week

let the number of weeks be x

y= 30+5x----------1

Bill has $16 and saves $7 each

week.

y= 16+7x----------------2

equate 1 and 2

30+5x= 16+7x

30-16= 7x-5x

Bruno leaves Ms. Crabbe's office to return to the gym. As he moves 450 meters in 2 minutes, what is his velocity? Be sure to write out your units of measurements for distance, time,

Answers

Answer: 225 meters per second

Step-by-step explanation:

Bruno was able to reach 450 meters in just 2 minutes.

His velocity therefore, can be determined by the speed formula which is:

= Distance / Time

= 450 / 2

= 225 meters per second

= 225 m/s

His velocity is 225 m/s.

Please help with this right triangle problem

Answers

Given:

The figure of a right angle triangle.

To find:

The measure of side AB.

Solution:

In a right angle triangle,

[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]

In the given triangle,

[tex]\cos B=\dfrac{BC}{AB}[/tex]

[tex]\cos (20^\circ)=\dfrac{7}{AB}[/tex]

[tex]\cos (20^\circ)AB=7[/tex]

[tex]AB=\dfrac{7}{\cos (20^\circ)}[/tex]

On further simplification, we get

[tex]AB=\dfrac{7}{0.93969}[/tex]

[tex]AB=7.449265[/tex]

[tex]AB\approx 7.45[/tex]

Therefore, the measure of AB is 7.45 units.

Name the slope and y-intercept of the graph of 3x - 2y = 18 A. B. 2 3 -6 6 C. -3.-9 D. 2 -9​

Answers

Answer:

D. 3/2, -9

Step-by-step explanation:

First, rearrange the equation 3x - 2y = 18 into the slope-intercept form of y = mx + b:

3x - 2y = 18

2y = 3x - 18

y = 3x/2 - 9

from this, u can tell that the slope is 3/2 and the y-intercept is -9 (option D)

state the domain of function, pa help po pls

Answers

Given:

The functions are:

(1) [tex]h(x)=\sqrt{1-x}[/tex]

(2) [tex]x+y=4[/tex]

(3) [tex]x^2+y^2=16[/tex]

To find:

The domain of given functions.

Solution:

Domain is the set of input and x -values.

Value under the square root must be positive because if the number under square root is negative, then it is a complex or imaginary number.

(1) [tex]h(x)=\sqrt{1-x}[/tex]

The function is defined if

[tex]1-x\geq 0[/tex]

[tex]1\geq x[/tex]

The function is defined for all real values of x which are less than or equal to 1.

Therefore, the domain of the function is (-∞,1].

(2) [tex]x+y=4[/tex]

It is a linear function and linear function is defined for all real values of x.

Therefore, the domain of the function is (-∞,∞).

(3) [tex]x^2+y^2=16[/tex]

It can be written as

[tex]y^2=16-x^2[/tex]

[tex]y=\pm \sqrt{16-x^2}[/tex]

It is defined if

[tex]16-x^2\geq 0[/tex]

[tex]16\geq x^2[/tex]

[tex]4\geq x\geq -4[/tex]

This function defined for all real values of x from -4 to 4.

Therefore, the domain of the function is [-4,4].
