Help. I have a D in this class.

Complete the square to re-write the quadratic function in vertex form:

Answer:

i = - 5

Step-by-step explanation:

Given

2i - 3 = 2(6 - i) + 7i ← distribute and simplify right side

2i - 3 = 12 - 2i + 7i

2i - 3 = 12 + 5i ( subtract 5i from both sides )

- 3i - 3 = 12 ( add 3 to both sides )

- 3i = 15 ( divide both sides by - 3 )

i = - 5

Answer:

27607.36 meters per hour

Step-by-step explanation:

400/52.16 = 7.66871165644

7.66871165644 meters per second

7.66871165644 × 60 = 460.122699386 meters per minute

460.122699386 * 60 = 27607.3619632 meters per hour

27607.3619632 meters per hour

Answer:

4,500 different codes.

Answer:

Table 1 does not represent a function.

Table 2 does not represent a function.

Step-by-step explanation:

                                                 Table 1

Input (x)               1             3          5              5           9        

Output (y)             7            16         19             20       28

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

Table 1 indicates that x = 5 is repeated twice. In other words, the input x = 5 is duplicated and we know that we can not have duplicated inputs as there should be only 1 output for each input.

Therefore, table 1 does not represent a function.

                                              Table 2

Input (x)               0.5         7          7               12        15      

Output (y)              1           15         10             23        30

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

Table 2 indicates that x = 7 is repeated twice. In other words, the input x = 7 is duplicated and we know that we can not have duplicated inputs as there should be only 1 output for each input.

Therefore, table 2 does not represent a function.

Conclusion:

We have concluded that both tables do not represent the function.

Answer:

x=7

Step-by-step explanation:

x+3x+2x-1=41 cm

6x-1=41

6x=41+1

6x=42

x=42/6

x=7

Answer:

1/8

Step-by-step explanation:

Let

The total fraction of the book read = 1

The remaining 4 days be represented as= x

Hence:

1 = Fraction of book read on Monday + Fraction of the book read on Tuesday + Fraction of the book on the remaining 4 days

1 = 1/6+ 1/3 + x

x = 1 - (1/6+ 1/3)

x = 1 - (1 + 2/6)

x = 1 - (3/6)

x = 1 - 1/2

x = 1/2

The fraction of the book read in 4 days = 1/2

To calculate the fraction of the book read on each of the days, since he read the same number of pages on each of the days we have:

1/2 ÷ 4 days

= 1/2 × 1/4

= 1/8

Therefore, the fraction of the book that was read on each of the 4 days is 1/8

Answer:

I believe it's SAS, but I am not 100% sure. I say this because you see the angle then in between is a side then another angle

Answer:

It decreases

Step-by-step explanation:

Hope you don't need an explanation, it decreases is the real answer.

Step-by-step explanation:

Since UV bisects TW, TW also bisects UV.

=> Line segments UV and TW bisect each other.

=> 4y - 3 = 2y + 1 and 3x + 8 = 3y + 2

=> 2y = 4 and 3x = 3y - 6

=> y = 2 and x = y - 2

=> y = 2 and x = (2) - 2

=> y = 2 and x = 0.

Answer:

y= 181/7 or 25.86

i really dont know about x

Answer:

His typing speed is 24 wpm. (Words Per Minute).

Step-by-step explanation:

The first thing you would have to do is convert 2/3 into a decimal, so 2/3 converted into a decimal is 0.66666666666667, then you would take that number, and multiply that by 36, the you would get you answer of 24. So, Kelly's typing speed is 24 wpm. (words per minute).

Answer:

Step-by-step explanation:

RS + ST = RT

6y + 3 + 4y + 7 = 60

6y + 4y + 3 + 7 = 60

       10y + 10   = 60

                  10y = 60 - 10

                 10y = 50

                    y = 50/10

y = 5

RS = 6*5 + 3 = 30 +3 = 33

ST = 4*5 + 7 = 20 + 7 = 27

Step-by-step explanation:

[Diagram in image attached]

RS + ST = RT

(6y +3) + (4y + 7) = 60

6y + 3 + 4y + 7 = 60

10y + 10 = 60

10y = 60 - 10

10y = 50

y = 50/10

y = 5

RS = 6y +3 = 6(5) + 3 = 30 + 3 = 33

ST = 4y +7 = 4(5) + 7 = 20 + 7 = 27

RT = 60

{RS + ST = RT

33 + 27 = 60}

Answer:

You will pay $19.6 for a item with original price of $24.50 when discounted 20%. In this example, if you buy an item at $24.50 with 20% discount, you will pay 24.50 - 4.9 = 19.6 dollars.

Answer:

Step-by-step explanation:

Given:

Present number of trees = 2.5 billions

Rate of decrease = 0.5% per month

To find:

The expression that represents how many trees will be left in 10 years?

Solution:

Exponential decay model:

[tex]P(t)=a(1-r)^t[/tex]         ...(i)

where, a is initial value, r is decreasing rate and t is time period.

We have,

a = 2.5 billions

r = 0.5% = 0.005 per month

t = 10 years = 120 months                         [1 year = 12 months]

Putting a=2.5, r=0.005 and t=120 in (i), we get

[tex]P(120)=2.5(1-0.005)^{120}[/tex]

[tex]P(120)=2.5(0.995)^{120}[/tex]

[tex]P(120)=1.3699657[/tex]

[tex]P(120)\approx 1.37[/tex]

Therefore, the required expression is [tex]2.5(1-0.005)^{120}[/tex] and the remaining trees after 10 years is about 1.37 billions.

[tex]C= 28.3 \ \ feet[/tex]

Step-by-step explanation:

Formula for Circumference is

[tex]C=2\pi r[/tex]

We know radius is half of diameter

[tex]r=\frac{d}{2} \\r=\frac{9}{2}[/tex]

[tex]C=2(3.14)\frac{9}{2}[/tex]

[tex]C=(3.14)9\\C=28.3 feet[/tex]

Answer:

Not exactly, if a possitive and a negetive are added together the number that was larger will choose its symbol. Say "k" is -3, so -3 + 2 = -1, or if "k" was -1, then -1 + 2 = 1.

Answer:

10.5

Step-by-step explanation:

Both widths are the same in a rectangle. So both are 6.5. Then you subtract 13 from 34. Now you are left with 21. No divide that by two to get your two lengths. That is l. L=10.5

Answer:

Step-by-step explanation:

P=2L+2W

P=34        W= 6.5

34=2L+2*6.5

34=2L+13

2L=21

L=10.5

or

Given:

P = 34 [Perimeter]

W = 6.5 {let's use W and L to make it easy to read]

Also known:

P = W + L + W + L = 2(W+L)

Fill in values:

34 = 2(6.5+L) [NOTE: This is an equation to determine the length (L) of the rectangle."]

. . .

17 = 6.5 + L [NOTE: This is a simplified form of the above equation.]

. . .

10.5 = L [NOTE: This is the solution (the value of L)]

Answer:

b

Step-by-step explanation:

Answer:

The missing base b is 3 units

Step-by-step explanation:

Let us solve the problem

In the given figure

∵ The given figure is a parallelogram

∵ The line of length 7 is perpendicular to the base that parallels to base b

∵ The base b has a height of 7 units

→ By using the formula of the area above

∵ A = b1 × h1

∵ b1 = b and h1 = 7 units

∵ The parallelogram has an area of 21 square units

∴ A = 21

→ Substitute the value of A and h in the rule of the area

∵ 21 = b × 7

∴ 21 = 7b

→ Divide both sides by 7

∴ 3 = b

∴ The missing base b is 3 units

Answer:

the answer is b
