The parabola with equation y = a(x – 2)^2 + q passes through the points (-2,5) and (4, -1) Determine the coordinates of the vertex of the parabola.
please help!
Step-by-step explanation:
the standard form for a quadratic function is
y = ax² + bx + c
our parabola had the equation
y = a(x - 2)² + q
let's do the "math" :
y = a(x² - 4x + 4) + q = ax² - 4ax + 4a + q
so, we know (when comparing with the standard form)
b = -4a
c = 4a + q
for the vertex we need to find the axis of symmetry first by using the standard formula
x = -b/2a
which is in our case
x = -(-4a)/2a = 4a/2a = 2
to get y for this x we need to find a and q first.
we are using the given points for that :
5 = a(-2)² - 4a×(-2) + 4a + q
-1 = a(4)² - 4a×4 + 4a + q
the first equation then forms into
5 = 4a + 8a + 4a + q = 16a + q
the second equation forms into
-1 = 16a - 16a + 4a + q = 4a + q
let's subtract the second from the first equation
5 = 16a + q
- -1 = 4a + q
--------------------
6 = 12a + 0
12a = 6
a = 1/2
-1 = 4a + q = 4×1/2 + q = 2 + q
q = -3
so, the original equation for our parabola is
y = 1/2 × (x - 2)² - 3
so y for the vertex (remember, x = 2) is
y = 1/2 × (2 - 2)² - 3 = 1/2 × 0 - 3 = -3
so the vertex is (2, -3)

On Monday Tom takes 15 minutes to walk one mile to school. On Tuesday
he takes 20 minutes to walk the same distance. Calculate his speed in mph
for each day's walk.
Answer:
Tom's speed (in mph) on Monday [tex]=4mph[/tex]
Tom's speed (in mph) on Tuesday [tex]=3mph[/tex]
Step-by-step explanation:
Using Speed distance time formula.
Tom's speed (in mph) on Monday
[tex]=Distance/time.[/tex]
[tex]=1/(15/60).[/tex] [By question statements, [tex]1hr=60min].[/tex]
[tex]=4mph[/tex]
Tom's speed (in mph) on Tuesday
[tex]=Distance/time.\\ =1/(20/60).[/tex][By question statements, [tex]1hr=60min].[/tex]
[tex]=3mph.[/tex]
Hence
Tom's speed (in mph) on Monday[tex]=4mph.[/tex]
Tom's speed (in mph) on Tuesday[tex]=3mph.[/tex]
I hope this helps you
:)
On Monday, The speed of Tom will be 4 mph.
On Tuesday, The speed of Tom will be 3 mph.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
On Monday Tom takes 15 minutes to walk one mile to school.
On Tuesday he takes 20 minutes to walk the same distance.
Now,
For Monday;
Tom takes 15 minutes to walk one mile to school.
Hence, Distance = 1 mile
Time = 15 minutes = 15/60 hour
Thus, Speed = Distance / Time
= 1 / (15/60)
= 60/15
= 4 mph
For Tuesday;
Tom takes 20 minutes to walk one mile to school.
Hence, Distance = 1 mile
Time = 20 minutes = 20/60 hour
Thus, Speed = Distance / Time
= 1 / (20/60)
= 60/20
= 3 mph
Thus, On Monday, The speed of Tom will be 4 mph.
On Tuesday, The speed of Tom will be 3 mph.

A rectangular room has a 10ft by 8ft rug in the center such that the distance from the edge of the rug to the wall is the same on all four sides. If the area of the room is 288 square feet, find the distance the rug is from the wall.
The answer I got was 13ft away, can someone check me on that?
Answer:
You are correct if rounding to the nearest whole number.
I got 12.69 so if you round up, you will get 13 (see below)
Step-by-step explanation:
X*Y = 288
(X-a)*(Y-a) = 10 * 8 = 80
X-a = 10
Y-a = 8
a = Y-8 = X-10
(X-10) * X = 288
X^2 - 10X = 288
X^2-10X-288= 0
quadratic equation
[tex]X = \frac{10 +/- \sqrt{100 - (4)(-288)} }{2}[/tex]
X = (10 + 35.38)/2 =22.69 (technically it would have 2 answers, but we only want to evaluate the positive answer)
a = X- 10 = 22.69- 10 = 12.69 which would round up to 13 if you are rounding to the nearest whole number.

Step-by-step explanation:
A company is using the first two years of its profits to predict what will happen in the future. The profit, p(x), in millions, can be modeled by
the function p(x) =x^2 + 4x + 5, where x, represents the number of years after 2020
- In what year did the company have the largest profit and what was the amount?
Answer:
2022
9 million
Step-by-step explanation:
[tex]p(x) =-x^2 + 4x + 5[/tex]
To find the value of x when the maximum profit occurs, differentiate the function:
[tex]\implies p'(x)=-2x+4[/tex]
set it to zero and solve for x:
[tex]\implies p'(x)=0[/tex]
[tex]\implies -2x+4=0[/tex]
[tex]\implies x=2[/tex]
Therefore, the year in which the company had its largest profit was
2020 + 2 = 2022
Input found value of x into the function:
[tex]p(2) =-(2)^2 + 4(2) + 5=9[/tex]
Therefore, the amount was 9 million

growth or decay, and determine the percentage rate of increase or decrease.
y = 59(0.59)
This equation represents exponential decay. Whenever the base is less than 1, the function represents decay. When the base is greater than 1, the function represents growth. In this case, the base is .59 which is less than 1, representing decay.

Those homeworks are so easy lmaøoo
Answer:
To graph the equation of a line written in slope-intercept (y=mx+b) form, start by plotting the y-intercept, which is the b value. The y-intercept is where the line will cross the y-axis, so count up or down on the y-axis the number of units indicated by the b value. From the y-intercept point, use the slope to find a second point. The numerator of the slope tells you how many units to move up or down from the intercept, and the denominator of the slope tells you how many units to move left or right in order to plot the second point. Connect the two points and draw arrows at either end to indicate that the line extends infinitely.
Step-by-step explanation:
Since the equation is in y=mx+B form, M is the value of we can use B as the Y_Intercept and M as the slope.

Answer:
6 people
Step-by-step explanation:
2 1/4 = 9/4 = 18/8
She gave 3/8 of a bag to each of the people => she gave 18/8 : 3/8 = 6 people
So, there are 6 people that live on Janet's block (maybe 7 if count Janet herself)
Answer:
6
Step-by-step explanation:
2.25 divided by 3/8 (0.375)
To double check multiply 3/8 by 6 and you'll get 2.25 (2 1/4).

A. 10,000 m³
B. 1,000 m³
C. 100 m³
D. 30 m³
In this exercise we have to use the formula for volume of the cube and we find that:
Volume of cube is 1000m³
How is volume calculated?The formula is V = c * l * a, where:
V = volume, c = length, l = width, a = height.Given that the length of side of cube = 10m, and knowing the formula the volume of cube is:
[tex]Volume of cube = (side)^3\\Volume of cube= (10)^3\\Volume of cube = 1000 m^3[/tex]

The debt owed is 910$ and the minimum payments is 2.5% or ten dollars whatever is larger. Assume Zach is going to pay only the minimum. If he only pays minimum it would take him 154 months.
Answer:
Monthly rate: 19%/12 ≈ 1.5833%72 months to pay off the loanStep-by-step explanation:
The monthly interest rate is the annual rate (APR) divided by 12.
19%/12 ≈ 1.5833%
The loan will be paid in fewer than 91 months, because Zach will be paying at least $10 per month on his current balance of $910. The attached spreadsheet shows it will take 73 payments to pay off the loan.

Step-by-step explanation:
[tex]10^{x-3.6}-7=41[/tex]
Add 7 to both sides:
[tex]\implies 10^{x-3.6}=48[/tex]
Taking logs of base 10:
[tex]\implies \log_{10}10^{x-3.6}=\log_{10}48[/tex]
Apply log rule [tex]\log a^b=b \log a[/tex]:
[tex]\implies (x-3.6)\log_{10}10=\log_{10}48[/tex]
Apply log rule [tex]\log_aa=1[/tex]:
[tex]\implies (x-3.6)\times 1 =\log_{10}48[/tex]
Simplify and solve:
[tex]\implies x-3.6=\log_{10}48[/tex]
[tex]\implies x=\log_{10}48+3.6[/tex]
[tex]\implies x = 5.281241237...[/tex]
[tex]10^{x-3.6}-7=41[/tex]
Use the rules of exponents and logarithms to solve the equation.
[tex]10^{x-3.6}-7=41[/tex]
Add 7 to both sides of the equation.
[tex]10^{x-3.6}=48[/tex]
Take the logarithm of both sides of the equation.
[tex]log(10^{x-3.6})=log(48)[/tex]
The logarithm of a number raised to a power is the power times the logarithm of the number.
[tex](x-3.6)log(10)=log(48)[/tex]
Add 3.6 to both sides of the equation.
[tex]x=log(48)-(-3.6)[/tex]
Solve by first finding [tex]log(48)[/tex] then subtract [tex](-3.6)[/tex] from the answer:
1. [tex]log(48)=1.6812412373755872181499834821531[/tex]
