Answer:

[1].

Option A and D are correct.

[2].

Option A is correct

Step-by-step explanation:

[1].

Quadratic function states that it is an equation of second degree i.,e it contains at least one term that is squared.

The standard form of the quadratic equation is; $ax^2+bx+c = 0$

$y(y+4)-y = 6$

Using distributive property: $a\cdot (b+c) = a\cdot b + a\cdot c$

$y^2+4y-y=6$

Combine like terms;

$y^2+3y = 6$

$y^2+3y -6=0$ which represents a quadratic equation.

$3a-7 = 2(7a-3)$

$3a-7 = 14a-6$

$11a+1 = 0$ which is not a quadratic equation.

(3x+2)+(6x-1) = 0

Combine like terms;

9x +1 = 0 which is not a quadratic equation.

4b(b) = 0

$4b^2 = 0$ which represents the quadratic equation.

Given the parent function: $y=x^2$

The reflection rule over x axis is given by;

$(x, y) \rightarrow (x, -y)$

then

the function become: $y = -x^2$

Vertical shift:

If c is a positive real number, the graph y=f(x)+c is the graph of y =f(x) shifted upward c units.

If c is a positive real number, the graph y=f(x)-c is the graph of y =f(x) shifted downward c units.

then;

The graph $y=-x^2-3$ is the graph of $y=-x^2$ shifted 3 units down.

Therefore, the translation of the graph of $y=x^2$ to obtain $y=-x^2-3$ is, reflect over the x-axis and shift down 3

Carol's car average is 17.1 miles per gallon in City driving and 24.7 miles per gallon in highway driving if she drove a total o

xxTIMURxx [149]

Answer:

the volume of the gas used for city driving is 17 gallons

Step-by-step explanation:

Given;

average speed for city driving, v₁ = 17.1 miles per gallon

average speed for highway driving, v₂ = 24.7 miles per gallon

total distance traveled, d = 513 miles

total gallon of gas used, t = 26 gallons

Let the volume of gas used for city driving = x

Also, let the volume used for highway driving = y

x + y = 26 -------- (1)

17.1x + 24.7y = 513 ------------(2)

From equation (1); y = 26 - x

Substitute the value of y in equation (2)

17.1x + 24.7(26-x) = 513

17.1x + 642.2 - 24.7x = 513

17.1x - 24.7x = 513 - 642.2

-7.6x = -129.2

x = 129.2/7.6

x = 17 gallons

Therefore, the volume of the gas used for city driving is 17 gallons

Can someone please help me with math.

vovangra [49]

Answer:

The answer would be B

Step-by-step explanation:

From 1 second to 3 seconds Denise had stopped

We can tell that this is true because looking at the graph we can see that from 1 to 3 seconds the distance stayed the same which indicates that Denise was not walking

Does anyone know how to find initial velocity with out acceleration or distance given

QveST [7]

The relevant formulas depend on what you do know, please advise.

If the acceleration you are missing is gravity than that is a known constant (9.8 m/sec^2). The formulas for projectile motion are:

y = yi + visin(A)t +.5gt^2
x = xi + vicos(A)t

with:
yi = equal to initial vertical position
xi = equal to initial horizontal position
vi = initial speed
A = angle from the horizon
t = time
g = gravitational acceleration (see above)

You can differentiate these equations to give the x' and y' components of velocity as a function of time. If you want me to do it you can write out the whole problem.
I hope this helps.
