Answer:
[tex]y=-4x^2+8x-1[/tex]
Step-by-step explanation:
I am assuming the parabola has his axis parallel to the y axis. You should remember from theory that the axis (and thus the first coordinate of the vertex) is [tex]-\frac b{2a}[/tex] and then you have two points of passage.
[tex]-b/2a = 1\\a(1)^2 +b(1)+c =3\\a(2)^2+b(2)+c=-1\\[/tex]
Let's solve subtracting the 3rd from the second and keeping the first as is (ok, slightly rewriting it).
[tex]2a=-b\rightarrow 2a+b =0 \\a+b+c=3\\4a+2b+c=-1\\III-II: 4a+2b+c-a-b-c=-1-3 \rightarrow 3a+b=-4 \rightarrow a +(2a+b)=-4\\a= -4; b=8; c =3 +4 -8 =-1[/tex]
My answer was incorrect and I don't know how to delete an answer

Which graph passes the vertical line test?
A.
B.
C.
D.
Answer:
Graph C.
Step-by-step explanation:
The rest of the graphs fail the vertical line test. This means some inputs (x values) contain more than one output (y value).
Answer:
C
Step-by-step explanation:
If a vertical line intersects the graph in some places at more than one point, then the relation is NOT a function.
answer choices A, B, and D intersect at more than one point vertically. Therefore, C is the correct answer.
Mario zombie walks at a rate of 2 miles per hour looking for a brainy snack. If it looks 514 hours, how many miles will it walk?

C.
Principal = $220, Interest = $200
D.
Principal = $220, Interest = $20
what is the answer.
Answer:
B. Principal = $200, Interest = $20Step-by-step explanation:
Principal + Interest = TotalWe have:
Principal = 200 and Total = 220The interest is:
220 - 200 = 20Correct choice is B
Total=$220
Principal=$200

The required solutions are as
(a) The amount owed at the end of 1 year is $ 5,040.
(b) The amount owed at the end of 2 years is $5644.8.
As mentioned in the question, a loan of $4500 is given at an interest rate of 12% compounded each year.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Here
(a)
The amount owed at the end of 1 year
= 4,500 × 12/100
= 540
Amount = 540+4,500
= $5,040
(b)
The amount owed at the end of 2 years
= 5,040 × 12/100
= 604.8
Amount = 5040 + 604.8
Amount = $5644.8

Answer:
ST = 164.21 m
Step-by-step explanation:
The fraction RU/UV have to be equal to RS/ST, because the triangles are similar:
190/120 = 260/ST
Multiply both sides by ST:
190ST/120 = 260
Multiply both sides by 120:
190ST = 260•120
Divide both sides by 190:
ST = 31200/190
ST = 164.21 m

a 6-pack of undershirts cost $13.98 this $3.96 less than the cost of buying 6 individual shirts. if each undershirts costs the same amount, how much does each undershirts cost when purchased individually
Answer:
Each undershirt costs $2.99 when purchased individually.
Step-by-step explanation:
The problem says that $13.98 is $3.96 less than the cost of buying 6 individual shirts which means that the total cost of buying 6 individual shirts is $17.94.
To find the price of 1 individual shirt, you divide 17.94 by 6. When you do this, you get $2.99. $2.99 is the cost of each undershirt when purchased individually.
Hope this helps!

how to find domain and range of a function
Answer:
The domain is found depending on the information you're given. In a table, the domain is found by taking all the x values given and listing them least to greatest. Same with ordered pairs. In a graph, the domain is found by first seeing if there are any restrictions and then find the x values that work and have one output.
The range is found the same way, but with the y values.

Calculate the area of this triangle.
14 cm
11 cm
18 cm
Answer:
73 cm (Estimated)
Step-by-step explanation:
Let's use hero's formula to solve this.
=> 1/2(14 + 11 + 18) = S
=> 1/2(43) = S
=> S = 21.5
√s(s - a)(s - b)(s - c)
=> √21.5(21.5 - 14)(21.5 - 11)(21.5 - 18)
=> √21.5 x 7.5 x 9.5 x 3.5
=> 73.2226911551 = Area of triangle

A company has developed a training procedure to improve scores on the
SAT. Following the training, 100 high school students take the SAT. The average math score is 517, with s = 90. Assuming u = 500 for the math SAT, test
the null hypothesis. Did the training significantly improve scores (a = .05,
directional)?
Answer:
The calculated t-test = 1.717 < 1.6604 at 0.05 level of significance
Null hypothesis is accepted at 0.05 level of significance
A company has developed a training procedure is significantly improve scores
Step-by-step explanationStep(i):-
Given sample mean (x⁻ ) = 517
sample standard deviation (s) =90
Mean of the Population (μ) =500
Null Hypothesis :- H₀ : (μ) =500
Alternative Hypothesis : H₁ : μ ≠ 500
Step(ii):-
Test statistic
t = \frac{x^{-} -mean}{\frac{s}{\sqrt{n} } }
t = \frac{517 -500}{\frac{90}{\sqrt{100} } }
t = 1.717
Level of significance
∝ = 0.05
t₀.₀₅ = 1.6604
The calculated t-test = 1.717 < 1.6604 at 0.05 level of significance
Conclusion:-
Null hypothesis is accepted at 0.05 level of significance
A company has developed a training procedure is significantly improve scores
