Write the equation of the parabola that has the same shape as f(x)=-3 x² but with vertex (5,9) in the form f(x)=a(x-h)²+k.
f(x)=
The equation of the parabola from the vertex is f(x) = -3(x - 5)² + 9
How to determine the equation of the parabola?The equation of the function is given as
f(x) = 3x²
Also, we have
Vertex = (5, 9)
The form of the equation is given as
f(x) = a(x - h)² + k
Where
Vertex = (h, k)
This means that
Vertex = (h, k) = (5, 9)
Substitute (h, k) = (5, 9) in the equation f(x) = a(x - h)² + k
So, we have
f(x) = a(x - 5)² + 9
This also means that
f(x) = -3(x - 5)² + 9
The -3 is gotten from f(x) = -3x²
Hence, the equation of the parabola is f(x) = -3(x - 5)² + 9

Work out 132% of 96 m

a plant is already 11 centimeters tall, and it will grow one centimeter ever month.Let H be thed plants height(in centimeters) after M months. Write an equation realted H to M
The growth follows a linear equation, for that we need
y = mx + c
The number of months would be the x axis as that is the thing changing, and the height would be the y axis as that is the thing being measured to change.
That now gives us
H = mM + c
m is the gradient and c is the y intercept
We can figure out the gradient because after 1 month the height increases by 1 so the change in y vs the change in x is 1 so the gradient must be 1.
The y intercept in this case is the initial condition and therefore is 11cm.
The final answer being
H = M + 11

The solution of the system equation is (-4,-11).
What is system equation?
One or more equations involving a number of variables make up a system of equations. The variable mappings that satisfy each component equation, or the points where all of these equations cross, are the solutions of systems of equations.
Here the given system equation is,
=> y = 5/2x-1------->1
=> t=2x-3---------->2
Put 1 into 2 then
=> 5/2x-1=2x-3
=>1/2 x=-2
=> x=-4
Put x=-4 into 2 then,
=> y=-8-3=-11.

3. Two of the vertices of an equilateral triangle are (0, -a)
and (0, a). The third vertex is on the x-axis to the right of
the origin. Name the coordinates of the third vertex.
The third coordinate of the equilateral triangle is [tex](\sqrt3a,0)[/tex]. Ir can be obtained by distance formula.
What is distance formula?
It gives the distance between two coordinates.
Distance formula is given by the following expression:
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Consider the third cordinate is (x,0) and x is positive because it is on tight side on the x axis.
Now, since the triangle is equilateral hence, the distance of (x,0) from (0, -a) and (0, a) should be equal to distance between (0, -a) and (0, a).
Now, caculate the distance between (0,-a) and (0, a).[tex]\sqrt{(0-0)^2+(-a-a)^2}=2a[/tex]
Now, distance between (x,0) and (0, a) should be 2a.
[tex]\sqrt{(x-0)^2+(0-a)^2}=2a\\\sqrt{x^2+a^2}=2a[/tex]
Now, square on both the sides.
[tex]x^2+a^2=4a^2\\x^2=3a^2\\x=\sqrt3a[/tex]and [tex]-\sqrt3a[/tex]
But the negative value of x is not possible because the coordinate lies on the right side.
Hence, the third coordinate of equilateral triangle is [tex](\sqrt3a,0)[/tex].

7 (4-x)=84
74-x)7=84/7
4-x-12
4-x-4=-12-4
-x=-16
-x/=1=-16/-1
=16
Answer Is=16 How do I Check my answer??
Answer:
x = - 8
Step-by-step explanation:
7(4 - x) = 84 ( divide both sides by 7 )
4 - x = 12 ( subtract 4 from both sides )
- x = 8 ( multiply both sides by - 1 )
x = - 8
As a check
substitute x = - 8 into the left side of the equation and if equal to the right side then it is the solution.
7(4 - (- 8) )
= 7(4 + 8)
= 7(12)
= 84 = right side
Then x = - 8 is the solution to the equation

The required equation is y = 23x - 9 which represents the total number of jumps.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
Mrs. Croaker’s class calculated that their class frog, named Fred, jumped 23 times every day, for 14 days in a row.
the total number of jumps = total days × number of jumps per day
the total number of jumps = 14 × 23
the total number of jumps = 322
We can see that two points are (1, 23) and (14, 322)
y - 14 = (322-23/14-1)(x - 1)
y - 14 = 23(x - 1)
y = 23x - 23 + 14
y = 23x - 9
Therefore, the required equation is y = 23x - 9 which represents the total number of jumps.

The rate of interest for an amount which is compounded quarterly is 4.25%
Given,
The principal amount invested by Oliver, P = $820
The time period of the investment, t = 19 years
The interest is compounded quarterly, n = 4
The amount after 19 years, A = $1830
The compound interest formula;
A = [tex]P (1+\frac{r}{n} )^{nt}[/tex]
We have to find the rate of interest;
For that;
A = [tex]P (1+\frac{r}{n} )^{nt}[/tex]
1830 = 820 [tex](1+\frac{r}{4} )^{76}[/tex]
1830/820 = [tex](1+\frac{r}{4} )^{76}[/tex]

1.) Solve the following equation for w: 3w-4(w-3) = 6
Answer: w=6
Step-by-step explanation: 1. Simplify. Distribute the -4 to the w and the -3. -4*w is -4w and -4*-3 is +12, so your left with 3w-4w+12=6.
2. simplify again. 3w-4w is -w.
3. -w+12=6. Subtract w to both sides, so its -w=-6. The negatives cancel out, so w just equals 6.
what is the slope of a line perpendicular to the line whose equation is 2x+2y=-12
Answer:
The slope of a line perpendicular to m=2 is m= 1.
Step-by-step explanation:
2x+2y=-12
2y=-2x-12
y= -x-6.
The equation is in slope-intercept form now, so it is easy to tell what the slope is.
The slope of y= -x-6 is m = -x. Technically, -x = -1x, so now make the -1 positive and find the reciprocal, which is still 1.
All you need to do to find the perpendicular slope of any line is simply to find the reciprocal of the number and make the positive/negative number the opposite. I hope this helps, have a good day/night! :)

The last function having the greatest rate of change.
What is rate of change?
The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one item by the equal amount of change in another.
Consider the first function,
From this function we get two points (2, 1) and (-2, -1).
To find rate using this points.
Rate = [tex]\frac{y_2-y_1}{x_2-x_1} = \frac{-1-1}{-2-2} = \frac{-2}{-4}=\frac{2}{4} =\frac{1}{2}[/tex]
Consider the second function,
The second function is a vertical line of x = -3.
Since the rate of vertical line is undefined.
Consider the third function,
The third function is a horizontal line y = 4.
Since two points having the same y - value.
Hence, the rate is zero.
Consider, the last function,
From last function we get two points (1, 5) and (-3, -3).
So,
Rate = [tex]\frac{-3-5}{-3-1} = \frac{-8}{-4} = \frac{8}{4} = 2[/tex]
