HELP PLEASE 13 POINTS

Answer:

correct answer is right

It's the slope of the secant line to f(x) through the points (-3, f (-3)) and (9, f (9)),

[tex]\dfrac{f(9) - f(-3)}{9 - (-3)} = \dfrac{-7 - 1}{12} = -\dfrac8{12} = \boxed{-\dfrac23}[/tex]

Answer:

[tex]we \: have \: ohms \: law \: h = {i}^{2} rt \\ \frac{h}{t} = {i}^{2} rt \div t = p \\ p = {i}^{2} r....(1) \\ we \: have \: v = ir \\ i = \frac{v}{r} .....(2) \\ put \: (2) \: in \: (1) \\ then \: p = { (\frac{v}{r}) }^{2} r \\ p = \frac{ {v}^{2} }{r} \\ v = \sqrt{pr} = {(pr)}^{ \frac{1}{2} } \\ 2) \\ here \: r = 32 \: and \: p = .5 \\ then \: v = \sqrt{32 \times .5} \\ = \sqrt{16} = 4volt \\ thank \: you[/tex]

Step-by-step explanation:

First as per the given question,

[tex]7 \frac{9}{10} + \frac{5}{10} [/tex]

[tex] = \frac{79}{10} + \frac{5}{10} [/tex]

[tex] = \frac{84}{10} [/tex]

[tex] = 8 \frac{4}{10} [/tex]

= 8 4/10 (Solution)

Here,

As we look in Maria,

She used a method where first she separated then added and got the result same as the solution.

And,

As we look in Paul,

He also used a method where first he added then separated and got the result same as the solution.

As we see,

Both having same results as the solution irrespective of different methods so both are correct in their way.

   Linear function is represented by the equation f(x) = mx + b

Where, m = rate of change and b = Initial quantity

  Function representing the total amount spent will be P(x) = 15x + 4000

Points to focus upon,

Let the number of guests over 200 are 'x'.

Therefore, amount of money spent on 'x' guests = $15x

And the number of guests in the party = 200 + x

Total amount spent on (200 + x) guests = $(4000 + 15x)

       If P(x) represents the total amount spent, function for the total expenditure will be,

P(x) = (4000 + 15x)

Answer:

S = 8

Each side of a face is 8 units.

Step-by-step explanation:

The surface area of the cube is 384 units.

One face of the cube has an area of s^2

A cube has 6 faces

6s^2 = 384                                 Divide by 6

s^2 = 384 / 6

s^2 = 64                                     Take the square root of both sides

sqrt(s^2) = sqrt(64)

s = 8

Answer:

8 units

Step-by-step explanation:

Area of 1 side = 384 ÷ 6 = 64 sq units

Length of 1 side = sq.rt. (64) = 8 units Answer

Answer:

Step-by-step explanation:

The fraction 5 divided by 1/2 looks like [tex]\frac{5}{1/2}[/tex]. It is difficult to divide with fractions but can be easier if you remember that dividing by a fraction is the same as multiplying by its reciprocal. A number's reciprocal is that number flipped by switching the numerator and the denominator. So, 3/5 becomes 5/3, and 1/2 becomes 2/1. Another way to state 2/1 is simply 2. Therefore, [tex]\frac{5}{1/2}[/tex] is really 5 * 2. 5 times 2 is 10, which is your answer.

Rewrite the fractions to have a common denominator:

1/3 = 8/24

3/8 = 9/24

Now add:

8/24 + 9/24 = 17/24 cups total

Answer:

x² + 4x + 12

Step-by-step explanation:

f(x) = x² + 2x + 9

f(x + 1) = (x + 1)² + 2(x + 1) + 9 = x² + 2x + 1 + 2x + 2 + 9 = x² + 4x + 12

Answer:

A'(-3, -2)

B'(-2, -1)

C'(-2, -2)

Step-by-step explanation:

The translation is (x - 7, y + 1).

That means subtract 7 from the x-coordinate and add 1 to the y-coordinate of each point.

Point A is (4, -3).

Subtract 7 from the x-coordinate 4 to get -3.

Add 1 to the y-coordinate -3 to get -2.

For point A, you get A'(-3, -2) after the translation.

Do the same with points B and C.

B(5, -2) ---> B'(5 - 7, -2 + 1) = B'(-2, -1)

C(5, -3) ---> C'(5 - 7, -3 + 1) = C'(-2, -2)

Answer:

20.525

Step-by-step explanation:

821/40=20.525

We're talking about points on the unit circle, which are coordinate pairs (x, y) that satisfy

x² + y² = 1

and the coordinates of point on the circle are governed by

x = cos(t)

y = sin(t)

If t = -35π/6, we have

x = cos(-35π/6) = cos(π/6) = √3/2

and

y = sin(-35π/6) = sin(π/6) = 1/2

because both cosine and sine have a period of 2π, which means

cos(θ) = cos(θ ± 2π) = cos(θ ± 4π) = …

and so on; in particular, we have cos(-35π/6) = cos(π/6) because

-35π/6 = π/6 - 6π

So t = -35π/6 corresponds to the point (√3/2, 1/2).

Answer:

-8 < r < 3

Step-by-step explanation:

Because you are trying to solve for r, all we have to do is isolate the variable.

To do this we can divide all 3 terms by -3, because that's what's in front of the r.

24/-3 > -3r/-3 > -9/-3

Dividing or multiplying by a negative number reverses this inequality, so the > signs must be flipped around to <

All that's left to do is simplify the fractions, and ensure that the inequality signs are flipped.
