put the quadratic into vertex form and state the coordinates of the vertex
y = x² + 6x - 41
Answer:
The vertex form of the quadratic: y = (x - 1)² + 2
Coordinates of vertex: (1, 2)
Step-by-step explanation:
The vertex form of an equation of the parabola is: f(x) = a(x - h)² + k
where (h, k) is the vertex. So:
x - h = x - 1 ⇒ h = 1
+ k = +2 ⇒ k = 2 -------------------------------------------------------------------------------

a cheeta can run 70 miles per hour. What is this speed in feet
Answer: 369,600 feet per hour.
Step-by-step explanation:
The correct answer to this question is that the cheetah can run 369,000 feet per hour. We can work this out in the following way:
One mile equals 1760 yards
In feet that is 3 x 1760 or 5,280
So Feet per hour will be 5280 x 70 or
369,600 feet per hour.
Answer:
6160 feet per minute

Step-by-step explanation:
A scatter plot was made to show the value of certain cars based on the age of the car in years. The equation of the scatter plot's trend line is y = -1,700x +
32,000 where y is the value of the car in dollars, and x is the age of the car in years.
Use the trend line equation to predict the value of a car after 7 years.
O A. $18.82
O B. $18,820
O C. $25,000
O D. $20,100
Answer:
I think it's D.
Step-by-step explanation:
So if the x is -1,700 and it stands for the years, then times it by 7. That would make -11,900. After you times it, add the 32,000 dollars and you would get $20,100. (I might have done the math wrong but I think this is the answer,)

How do I write the equation of a line that goes through the points (9,-8) and (6,-8)???
Answer: y=-8
Step-by-step explanation: I will assume you want the solution in slope intercept form. First, we must find the slope of this line. Since between the two points the y value doesn't change, this means our line is horizontal. So far, we have y=0x+b, since anything multiplied by 0 is zero, we can get rid of that. This line is a horizontal line, and we have the y value, so out equation is y=-8.

4d2–15d+9=0 solve for d
Answer:
d = 3 and d = 3/4
Step-by-step explanation:
This is a quadratic eqution. Let's use the quadratic formula to solve it.
If ax^2 + bx + c = 0, then:
-b ± √(b^2 - 4ac)
x = ---------------------------
2a
With a = 4, b = -15 and d = 9, we have:
-(-15) ± √(225 - 4(4)(9) ) 15 ±√81 15 ±9
d = ------------------------------------ = -------------- = -------------- = 24/8 and 6/8
2(4) 8 8
Simplifying these results, we get d = 3 and d = 3/4

There is a line that includes the point (4,8) and has a slope of 4 What is its equation in slope- intercept form
Answer:
y=4x-8
Step-by-step explanation:
1) The slope-intercept form of an equation looks like this:
y=mx+b
The m stands for the slope and the b stands for the y-intercept. We need two points on the line to write out this equation.
2)We have the slope you entered in, so we'll plug that in first:
y=4x+b
3) Now, let's plug in that point you entered in to solve for b:
y=4x+b
8=4(4)+b
8=16+b
8-(16)=b
-8=b
4) Now that we have both our slope, m, and our y-intercept, b, values, we can plug them in to get our equation:
y=mx+b
y=4x-8

The rate of population decline of Seaside
Harbor is modeled by the equation
-0.00810
P(t)=15000e
where t is the time
in years and 15,000 is the current
population. In approximately how many
years will the population of Seaside
Harbor be 9,000?
(−0.0081p)(t)=(15000)(2.718282)
Step 1: Divide both sides by -0.0081t.

Kishany is investing in a savings account that earns 3.85% interest compounded annually. How much will Kishany have in the account at the end of the 3rd year if she deposits $600 in the account?
a
$2,310
b
$672.00
c
$558.38
d
$669.30
Answer:
The amount in the account after 3 years is $672.00
Step-by-step explanation:
Here, we want to use the compound interest formula
A = P(1 + r/n)^nt
A is the amount in the account after the given time
P is the principal which is the deposit amount = $600
r is the interest rate = 3.85% = 3.85/100 = 0.0385
n is the number of times interest is compounded yearly (since it is annually, n = 1)
t is the time in years = 3
Substituting these values;
A = 600(1 + 0.0385/1)^(3 * 1)
A = 600(1.0385)^3
A = $672
Help Please!!!!!!! Need Help!!!
Answer:
925
Step-by-step explanation:
In order to solve this summation formula, you need to first understand what it means. The summation symbol is tell you to add the terms in a sequence. Below the summation sign, there is a variable and number; the variable n is the index of summation and the number 1 is the lower limit of summation or the first value of the sequence. The number 25 above the summation sign is the upper limit (so there would be 25 terms, with the first being 1). The polynomial to the right of the summation symbol represents the explicit function for each term. For example, using this, the first term would be (3(1) - 2) and the second (3(2) - 2) and so on. This means the value of that equation is:
(3(1) - 2) + (3(2) - 2) + (3(3) - 2)... + (3(25) - 2)
One way to solve this is to write all 25 of the terms and add them, but since that's tedious, you can solve this by first doing the basic summation of 1 to 25 and then inputting that into the equation:
1 + 2 + 3... + 25 = (25 × 26)/2 (when the first number is one and the rate of change is 1, the sum of the terms in a sequence is (n*(n+1))/2)
= 325
Now, that you know what the sum of the sequence of terms 1 to 25 are, you can multiply this by the constant since if you break up the equation you would be multiplying 3 by 1 then 3 by 2 and so on until 25, or 3 × (1 + 2 + 3... + 25):
3 × 325 = 975
At this point, you just need to add (-2) × 25. You do this because since there are 25 terms, if you subtracted 2 each time, you would subtract 2 twenty-five times:
975 + ((-2) × 25)
= 975 - 50
= 925

There are eight pints of lemonade an equal amount of lemonade is poured into 15 cups how much is in each cup
Answer: 8/15
Step-by-step explanation:
From the question, we are given the information that there are eight pints of lemonade and that an equal amount of lemonade is poured into 15 cups.
The amount of lemonade that's in each cup will be gotten by dividing the total pints of lemonade by the number of cups. This will be:
= 8 pints / 15
= 8/15 pints of lemonade
