[tex]f(x)=x^2-12x+46\\a=1\,,\ \ b=-12\\\\[/tex]

Vertex form of an equation of a quadratic function: f(x)=a(x-h)²+k, where vertex is (h, k) and:

[tex]h=\dfrac{-b}{2a}\,,\ \ k=f(h)\\\\\\h=\dfrac{-(-12)}{2\cdot1}=\dfrac{12}{2}=6\\\\k=f(6)=6^2-12\cdot6+46=36-72+46=10[/tex]

Answer:

No

Step-by-step explanation:

no you do not get the same answer

This is the order in which you should approach problems, doing otherwise may lead to a wrong answer

P - parenthesis -- meaning solve whatever is the the parenthesis

E - exponents -- an example of an exponent is [tex]2^{3}[/tex] which equals 8

MD - multiplication/division

AS - addition / subtraction

for our particular problem, we have

9 + 2(3)

multiplication trumps addition thus we perform multiplication first

9 + 6 = 15 ---CORRECT

if we were to addition first we would get

9 + 2(3) = 11(3) = 33 This would be WRONG

note: multiplication and division are on the same level

         subtraction and addition are on the same level

if you encounter a problem like 4 ÷ 2 * 3. perform the calculation from left to right thus we would have 4 ÷ 2 = 2 and then 2 * 3 = 6

same applies for addition subtraction

Answer:

16 °C

Step-by-step explanation:

We are told that Ken predicts that, in August, the average low temperature will be 20°C, and that the temperature will drop by 4°C in September.

Now, in a standard 12 month calendar, the month of August comes before the month of September.

Thus, in September a drop off by 4°C from 20°C means that the new temperature in September is; 20°C - 4°C = 16 °C

Answer:

16

Answer:

The 1st baseman can't catch the ball without jumping.

Step-by-step explanation:

To know if the 1st baseman can catch the ball without jumping we need to find the height reached by the baseball by solving the following equation:

[tex] f(x) = -0.004x^{2} + 0.3x + 6 [/tex]

We know that x (the horizontal distance) = 60 feet, so we have:

[tex] f(60) = -0.004(60)^{2} + 0.3(60) + 6 [/tex]

[tex]f(60) = 9.6 ft[/tex]

Since the 1st baseman can reach 8 ft high and the height reached by the baseball is 9.6 ft, the 1st baseman can't catch the ball without jumping.

Therefore, the 1st baseman can't catch the ball without jumping.

Sum of the numerator and denominator = 18

If the denominator is increased by 2 , the fraction reduces to 1/3.

the fraction

Let the fraction be x/y.

⟹ x + y = 18

⟹ x = 18 - y -- equation (1)

And,

If the denominator is increased by 2 , the fraction reduces to 1/3.

⟹ x/y + 2 = 1/3

⟹ 3x = y + 2

Substitute the value of x from equation (1).

⟹ 3(18 - y) = y + 2

⟹ 54 - 3y = y + 2

⟹ 54 - 2 = y + 3y

⟹ 52 = 4y

⟹ 52/4 = y

⟹ 13 = y

Substitute the value of y in equation (1).

⟹ x = 18 - 13

⟹ x = 5

Therefore, the required fraction x/y is 5/13.

I hope it will help you.

Answer:

Length is twice the breadth.

→ Length = 2 * x = 2x m.

Also,

Perimeter of the field = 150 m.

We know that,

Perimeter of a rectangle = 2(length + breadth).

Hence,

→ 150 = 2(x + 2x)

→ 150 = 2 * 3x

→ x = 150/2 * 3

→ x = 25

Answer:

y = - 3x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3 and c = 7 , thus

y = - 3x + 7 ← equation of line

Answer:

140 teenagers attended the game.

Answers:

There are eight items in that list above.

===================================

Explanation:

We'll use the AC method of factoring.

The first term has coefficient 3. The last term is -8. Multiply them to get 3*(-8) = -24.

Now let's list all the ways to multiply two integers to get -24

For each pair of factors listed, we'll add up those pairs. Each sum we get represents a possible value of k

Note the symmetry. For instance we have 10 as one sum and -10 as another sum.

-------------------------------

Let's go over an example. Let's say that k = 10

The expression 3x^2+kx-8 turns into 3x^2+10x-8

From the list above, we see that -2+12 = 10. So the two values -2 and 12 will help us factor.

Break up the 10x into -2x+12x and then factor by grouping like so

3x^2 + 10x - 8

3x^2 - 2x + 12x - 8

(3x^2 - 2x) + (12x - 8)

x(3x-2) + (12x - 8)

x(3x-2) + 4(3x - 2)

(x+4)(3x-2)

Therefore, 3x^2 + 10x - 8 factors into (x+4)(3x-2)

We can use the FOIL rule, distribution, or the box method to confirm this.

I'll let you try out other values of k to see how 3x^2+kx-8 factors.

Answer:

4,2

Step-by-step explanation:

The slope of the line is 2.

All you have to do is rise/ run.

Rises 6 runs 3.

So 6/3.

Simplify iff possible, and in this case it is possible. Which gives you 2.

Answer is 2.

Answer: 7.5%

Step-by-step explanation:

Given: Principal amount = $15,000

Time =- 2 years

Final Amount (Principal + interest)= $17,250

Interest = Final Amount - Principal amount

= $ ( 17250 - 15000  )

= $ 2250

Formula for interest : principal x rate x time

[tex]2250=15000\times rate \times 2\\\\\Rightarrow\ rate =\dfrac{2250}{15000\times2}\\\\\Rightarrow\ rate =0.075\\\\\Rightarrow\ rate =0.075\times100\%=7.5\%[/tex]

Hence, the simplest interest rate on lukes loan =7.5%

Answer:

write answer is 600,, 100% sure

Lol , so this question is from your school google forms? ; )

Answer is 600. Lemme show you how.

Y is proportional to x.

y ∝ x

to remove proportionality , we put k.

y = kx

Now , insert values of y and x to find k.

60 = k *75

k = 75 / 60

Now when Y = 480 , x =?

x = (75/60)(480) = 600.

X = 600

Ah yes.
