Find the vertex of the parabola. y = negative 4 x squared + 24 x minus 35 a. ( -3, 1) c. ( 3, 1) b. ( -3, -1) d. ( -1, -3)
Answer:
(3, 1)
Step-by-step explanation:
y = -4x² + 24x - 35
Find the vertex by using the formula:
(h, k) → [tex]\displaystyle \Big [ -\frac{b}{2a}, \ f \Big (-\frac{b}{2a} \Big ) \Big ][/tex]In this problem, we have:
a = -4 b = 24 c = -35Using 24 for b and -4 for a, we can substitute these values into the vertex formula:
[tex]\displaystyle -\frac{b}{2a} \rightarrow -\frac{24}{2(-4)} = \frac{-24}{-8} = 3[/tex]The h-value for the vertex is 3.
Now let's plug 3 back into the standard form equation to solve for the k-value of the vertex.
[tex]-4x^2 + 24x - 35 \rightarrow -4(3)^2+24(3)-35 = -36 + 72 - 35 = 1[/tex]The k-value for the vertex is 1.
The vertex of the parabola is (3, 1).

explanation:
4/5 + v = 41/20
solve this plz and show me how you got the answer
Answer:
v = 1 1/4 (1.25)
Step-by-step explanation:
4/5 + v = 41/20
16/20 + v = 41/20
16/20 16/20
---------------------------
v = 41/20 - 16/20 = (41-16)/20 = 25/20 = 5/4 = 1 1/4

QRINC offered new employees a starting salary of $34,862 in 2013. What would a comparable starting salary have been in 2003?
Answer:
[tex]C=27535.5881128[/tex]
Step-by-step explanation:
From the question we are told that
CPI for 2003(index)=2003-184.00
CPI for 2013(index)=2013-232.957
Starting salary in 2013 at $34,862
Generally comparable starting salary C is given as
[tex]C=\frac{starting salary}{CPI for 2013(index} *CPI for 2003(index)[/tex]
[tex]C=\frac{34,862}{232.957} *184[/tex]
Therefore C the comparable starting salary is givrn to be
[tex]C=27535.5881128[/tex]
[tex]C=27536 appro[/tex]
Amy's family drove to Lucky Land Fun Park for the day. Her dad and mom
shared the driving. Amy's dad drove 3 miles for every 5 miles her mom
drove. If Amy's mom drove 32 more miles than her dad, how many miles
did they drive altogether? (Draw a tape diagram to help you). *
Answer:
128 miles
Step-by-step explanation:
The number of miles Amy's parents drove altogether is 128 miles.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Amy's dad drove 3 miles for every 5 miles her mom
drove.
So, the ratio is 3:5
Amy's mom drove 32 more miles than her dad
Let number mile Amy's father drove be x and then the number of miles Amy's mom drove will be x+32
Here, x/(x+32) =3/5
5x=3(x+32)
5x=3x+96
2x=96
x=48
So, x+32=80
Then, total distance is 80+48=128 miles
Therefore, the number of miles Amy's parents drove altogether is 128 miles.
