[tex]h = - \frac{b}{2a} \\ k = \frac{4ac - {b}^{2} }{4a} [/tex]

[tex]y = a{(x - h)}^{2} + k [/tex]

Where the a-term determines how wide, narrow, upward or downward the graph is.

The h-term determines the horizontal shift of graph. (x-axis)

The k-term determines the vertical shift of graph. (y-axis)

The vertex of graph is at (h,k). We can find the vertex by using the given formulas.

From the equation, the coefficients are:

[tex] \begin{cases} a = - 1 \\ b = 12 \\ c = - 31 \end{cases}[/tex]

Substitute these values in the formulas.

Find the value of h

[tex]h = - \frac{12}{2( - 1)} \\ h = - \frac{12}{ - 2} \\ h = - \frac{ - 6}{1} \longrightarrow - ( - 6) = 6 \\ h = 6[/tex]

Hence, the value of h is 6.

Find the value of k

[tex]k = \frac{4( - 1)( - 31) - {(12)}^{2} }{4( - 1)} \\ k = \frac{124 - 144}{ - 4} \\ k = \frac{ - 20}{ - 4} \longrightarrow \frac{5}{1} = 5 \\ k = 5[/tex]

Hence, the value of k is 5. Then we substitute both value of h and k in the vertex form

[tex]y = a {(x - h)}^{2} + k \\ y = - 1 {(x - 6)}^{2} + 5 \\ y = - {(x - 6)}^{2} + 5[/tex]

Since the vertex is at (h,k). Therefore the value of h is 6 and k is 5. Therefore:

[tex] \large{(h, k)=(6, 5)}[/tex]

(6,5) is the vertex.

the answer is 90

8 and 1 are alternate exterior angles.

Answer:

<8 and <1

Step-by-step explanation:

<8 and <1 are both outside of the parallel so they are exterior and opposite to each other which is alternative exterior.

Answer:

0.004

Step-by-step explanation:

Just mutiply and divide by 2

Answer:

2

Step-by-step explanation:

combine like denominators:

(1-x^4)/(x^2+1)+(x^4-1)/(x^2-1)

factor:

(1-x^2)(1+x^2)/(x^2+1)+(x^2+1)(x^2-1)/(x^2-1)

reduce:

(1-x^2)+(x^2+1)

1+1=2

Answer:

5/8

Step-by-step explanation:

8/8-3/8=5/8

Answer:

A)

45% of customers were not satisfied with the graphics.

B)

22,500 people are expected to not be satisfied with the graphics.

6,500 people are expected to have no opinion.

C)

The majority of people are unsatisfied with the graphics.

Step-by-step explanation:

The company polled 1,000 out of the 50,000 people who had purchased the program.

42% was satisfied with the graphics.

And 13% had no opinion.

Part A)

When totaled, those satisfied, unsatisfied, and with no opinion should be 100%.

Since 42% are satisfied and 13% have no opinion, this leaves 100 - 42 - 13 or 45%.

So, 45% of customers were not satisfied with the graphics.

Part B)

Since 45% of the polled were unsatisfied with the graphics, 45% of the total 50,000 can also be expected to not be satisfied.

45% of 50,000 is 0.45(50000) = 22500.

So, 22,500 people are expected to not be satisfied with the graphics.

Likewise, 13% had no opinion.

So, 13% of 50,000 is 0.13(50000) = 6500.

6,500 out of the current 50,000 customers are expected to have no opinion with the graphics.

Part C)

Since the majority of people are unsatisfied with the graphics (45% > 42%), it is reasonable to create a new version with improved graphics.

Answer:

6.85 pounds

Step-by-step explanation:

3.2+1.75+1.9=6.85

Answer:

2950 [Starting from 2,000 bacteria.]

Step-by-step explanation:

400/8 = 50

Bacteria grown/time = bacteria per hour

19x50 = 950

time x bacteria per hour = bacteria grown

2000 + 950

bacteria started + bacteria grown

3x+5x+1=17

x=2

y=5•2+1

y=1

(x, y)=(2, 11)

3x+2(4x+5)=43

x=3

y=4•3+5

y=17

(x, y)=(3, 17)

Answer:

2.82842712475

Step-by-step explanation:

√8 = 2.82842712475

w = 24

work=

1000⁸=10w

write the expression in exponential form with the base of 10

10²⁴=10w

since the bases are the same, set the exponents equal

w=24

if you need it in slope intercept form too its y=3/4x-1

cevap:y=5 inşallah faydalı cevaptır

Answer:

Let's solve for x.

4x+5y=7

Step 1: Add -5y to both sides.

4x+5y+−5y=7+−5y

4x=−5y+7

Step 2: Divide both sides by 4.

4x/4=−5y+7/4

x=−5/4 y+ 7/4

Answer: for the first one x=−5/4 y+ 7/4

3x−2y=−12

Step 1: Add 2y to both sides.

3x−2y+2y=−12+2y

3x=2y−12

Step 2: Divide both sides by 3.

3x/3=2y−12/3

x=2/3y−4

Answer:

x=2/3y−4
