Which quadratic function in vertex form can be represented by the graph that has a vertex at (3, -7) and passes through the point (1, -10)?
I really need the answer QUICK please
Answer:
Answer is D
Step-by-step explanation:
(3,-7) and (1,-10) belong toD Variant
The required function is [tex]y=-\frac{3}{4}(x-3)^2-7[/tex] , so the correct option is D.
Important information:
Vertex = (3,-7)Other point = (1,-10)Quadratic function:The vertex form of a quadratic function is:
[tex]y=a(x-h)^2+k[/tex]
Where, [tex]a[/tex] is constant and [tex](h,k)[/tex] is vertex.
Substitute [tex]h=3,k=-7[/tex].
[tex]y=a(x-3)^2-7[/tex] ...(i)
Graph passes through the point (1, -10). Substitute [tex]x=1,y=-10[/tex] in (i).
[tex]-10=a(1-3)^2-7[/tex]
[tex]-10+7=4a[/tex]
[tex]-3=4a[/tex]
[tex]\dfrac{-3}{4}=a[/tex]
Substitute [tex]a=-\dfrac{3}{4}[/tex] in (i).
[tex]y=-\frac{3}{4}(x-3)^2-7[/tex]
Therefore, the correct option is D.

Factor this polynomial.
-3x² - 6x-2
Answer:
Doesn't factor
Step-by-step explanation:
We have a polynomial and are asked to factor it.
A rule I like to follow when factoring polynomials is what two numbers multiply to equal c (in this case -2) and add up to b (in this case -6x).
Since no two numbers are eligible to do this, therefore this polynomial is unfactorable.

Answer:
15 and 105
Step-by-step explanation:
well this should be simple
if a small car averages 29 miles MORE, and it averages 44, the. just take 44 - 29.. which is 15.
Well if he has to go 240 miles, and he’s drove 135, just take 240 - 135 = y
240 - 135 = 105
y = 105
Derrick needs to sell a minimum of 100 orders each month to make it into the sales winners circle. He has already sold 45 orders this month. He still needs to sell s more orders. Which inequality can be used to find the possible values for s? s−45>100
s−45<100 s+45≤100 s+45≥100
Answer:
s+45≥100
Step-by-step explanation:
"A minimum of" means either the same amount or more. So, the total amount he sells (s + 45) needs to be greater than or equal to 100.

The vertices of parallelogram DEFG are E(-1,4) F(5,6) and G (8,0). Find the coordinates of D
Answer:
The coordinates of D are (2,-2)
Step-by-step explanation:
The coordinates of point D are (2,-2)
The coordinates of the parallelogram are given as:
E(-1,4), F(5,6) and G (8,0)
For the coordinates to represent a parallelogram, the following must be true
[tex]x_D - x_E = x_G - x_F[/tex]
[tex]y_D - y_E = y_G - y_F[/tex]
So, the equations become
[tex]x_D -(-1) =8-5[/tex] and
[tex]y_D -4 =0-6[/tex]
Solve for x and y in the above equations
[tex]x_D -(-1) =8-5[/tex]
[tex]x_D +1 = 3[/tex]
[tex]x_D = 3-1[/tex]
[tex]x_D = 2[/tex]
[tex]y_D -4 =0-6[/tex]
[tex]y_D - 4 = -6[/tex]
[tex]y_D = 4-6[/tex]
[tex]y_D =-2[/tex]
Hence, the coordinates of point D are (2,-2)

Rosa deposits $5000 in a savings account that gets compounded interest annually at a rate of 8%. If she leaves her money in the account for 2 years, how much will she have at the end of that time?
Answer:
$5318
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
I = 2650 × 0.04 × 3 = 318
I = $ 318.00
The simple interest accumulated
on a principal of $ 2,650.00
at a rate of 4% per year
for 3 years is $ 318.00.

A total of 110 gallons of water can follow through Hose B in minutes. Which hose has a faster water ow rate, in gallons per minute, and what is that rate?
Answer:
Hose B
Step-by-step explanation:
Charles needs to fill a large fish tank with water using a hose. he has two hoses from which to choose. Water flows through each hose at a constant rate. The graph below shows the amount of water, in gallons , that flows through holes A based on the number of minutes used. A total of 110 gallons of water can flow through Hose B in 10 minutes. Which hose has a faster water rate, in gallons per minute, and what is that rate?
Solution:
The equation of a linear function is:
y = mx + b
where m is the rate of change and b is the initial value of y.
The equation of a line passing through two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
Let y represent the amount of water in gallons and let x represent the time in minutes.
For hose A, we can see that the graph passes through the point (0, 0) and (2, 12). Hence:
[tex]y-0=\frac{12-0}{2-0}(x-0) \\\\y=6x[/tex]
Therefore hose A has a flow rate of 6 gallons per minute.
110 gallons of water flow through hose B in 10 minutes. Therefore:
Flow rate of hose B = 110 gallons / 10 minutes = 11 gallons per minute
Therefore hose B has a higher flow rate
s=2πcx+3πc^2 solve for x
Answer:
x = (s - 3πc^2) / 2πc.

s = 2πcx + 3πc^2
2πcx = s - 3πc^2
x = (s - 3πc^2) / 2πc.
