Answer:

  a) -4

  b) 11

  c) a(1) = -4; a(n) = a(n-1) +11   (Maybe you want an = -4+11(n-1).)

  d) 95

Step-by-step explanation:

See the attached.

a) The value of a1 is given in the problem statement. It is -4.

__

b) If we take "d" to mean the common difference between terms, it is the value added to one term to get the next term. The recursive formula shows that value is 11.

__

c) The iterative rule for the sequence is given in the problem statement.

We suspect the intention is to ask for the explicit rule. That rule has the form ...

  an = a1 +d(n -1)

Using the values of a1 and d, we get the explicit rule ...

  an = -4 +11(n -1)

__

d) The recursive/iterative rule requires you find all previous terms in the sequence before you can learn the 10th term. The explicit rule allows you to substitute n=10 and compute the 10th term directly:

  a10 = -4 +11(10 -1) = -4 +99 = 95

The tenth term is 95.

Additional comment

We'd rather not have to try to guess the intended question. Perhaps you should discuss this question with your teacher. (recursive vs. iterative vs. explicit)

Step-by-step explanation:

An increasing linear function results in a graph that slants upward from left to right and has a positive slope. A decreasing linear function results in a graph that slants downward from left to right and has a negative slope. A constant linear function results in a graph that is a horizontal line.

Answer:

2 is the answer

Step-by-step explanation:

because 7 is going to make 1.75 round up to 2

It has been proven below that BF ║ CD.

    From the given diagram, we are told that;

ΔABF ≅ ΔBCD

      This means both triangles are congruent.

Now, in the two triangles, we can see that;

∠BAF ≅ ∠CBD

Because they are corresponding angles

    We also see that;

∠ABF ≅ ∠BCD

Because they are corresponding angles

Since point B is the midpoint of AC, then it means that;

AB = BC

          Thus, we can see that 2 corresponding angles are equal and the included corresponding side is also equal and as a result this fulfils the ASA Congruency Postulate.

Thus, for the fact that ∠ABF ≅ ∠BCD, it means that BF must be parallel to CD.

Answer:

9π

Step-by-step explanation:

Let a = circumfrence of circle a

     b = circumfrence of circle b

a = 3b

circumference = 2πr

diameter = 27

radius = 27/2 (radius is half of the diameter)

a = 2π(27/2)

a = 27π

Plug in the new a

27π = 3b

Divide both sides by 3

27π/3 = 3b/3

b = 9π

Answer:

To find the first blank number, you can use reverse operations. Something + 7 must equal 3. So, the blank number is 7 subtracted from 3.

3-7=-4

The first blank number is -4. To find the second blank number, add 10 to the first blank number (-4).

-4+10=6

The second blank number is 6.

1: The parent function of the quadratic family is f(x) = x2. A transformation of the graph of the parent function is represented by the function g(x) = a(x − h)2 + k, where a ≠ 0.

2:The absolute value function is defined by f (x) = |x|. This is the absolute value parent function. The graph of y = a|x| is graph of y = |x| vertically stretched or compressed depending on the |a|.

3:Reciprocal functions are functions that have a constant on their denominator and a polynomial on their denominator. The reciprocal of a function, , can be determined by finding the expression for 1 f ( x ) . We can graph a reciprocal function using the function's table of values and transforming the graph of y = 1 x .

  4√62.80 ≈ 31.6986

  62.80 ÷ 4 = 15.70

Step-by-step explanation:

Your calculator can help you find the values of these expressions. (It is a good idea to learn how to use it.)

a) The square root is calculated before the multiplication.

  4√62.80 ≈ 4×7.92465 ≈ 31.6986 . . . . . rounded to 6 significant figures

__

b) The division is performed in any of the usual ways.

  62.80 ÷ 62.80 = 15.70

Answer:

C = 0.35x + 100

Step-by-step explanation:

0.35 is the cost per mile, and x is the number of miles. Say if x is 10, meaning you went 10 miles, you would multiply that by 0.35 to get a cost of $3.50. So, use 0.35x . The $100 is added on because it doesn’t matter how many miles were driven, you still have to pay at least that much per day.

Equivalent equations are simply equations that have the same value, irrespective of their form

1. 7 + 5x = 3 - 2x and 7 + 7x = 3

Start by solving for x in both equations

[tex]\mathbf{7 + 5x = 3 - 2x}[/tex]

Collect like terms

[tex]\mathbf{2x + 5x = 3 - 7}[/tex]

[tex]\mathbf{7x = - 4}[/tex]

Divide both sides by 7

[tex]\mathbf{x = -\frac 47}[/tex]

[tex]\mathbf{7 + 7x = 3}[/tex]

Collect like terms

[tex]\mathbf{7x = 3-7}[/tex]

[tex]\mathbf{7x = - 4}[/tex]

Divide both sides by 7

[tex]\mathbf{x = -\frac 47}[/tex]

The values of x in both equations are the same;

Hence, 7 + 5x = 3 - 2x and 7 + 7x = 3 are equivalent

2. 3 (x – 4) = 15 and x-4 = 15

Rewrite the first equation as follows

[tex]\mathbf{3 (x - 4) = 15 }[/tex]

Divide both sides by 3

[tex]\mathbf{x - 4 = 5 }[/tex]

In the second equation, we have:

[tex]\mathbf{x-4 = 15}[/tex]

The values of x - 4 are not the same in both equations.

Hence, 3(x – 4) = 15 and x-4 = 15 are not equivalent

3. x2 = 6x and x = 6

Solve for x in the first equation as follows:

[tex]\mathbf{x^2 = 6x}[/tex]

Divide both sides by x

[tex]\mathbf{x = 6}[/tex]

The results of both equations are the same.

Hence, [tex]\mathbf{x^2 = 6x}[/tex] and [tex]\mathbf{x = 6}[/tex] are equivalent

4. (x+5) = 10 and 1 = 10(x – 5)

Solve for x in the first equation as follows

[tex]\mathbf{x+5 = 10}[/tex]

[tex]\mathbf{x = 5}[/tex]

Solve for x in the second equation as follows

[tex]\mathbf{1 = 10(x - 5)}[/tex]

Divide both sides by 10

[tex]\mathbf{0.1 =x - 5}[/tex]

Add 5 to both sides

[tex]\mathbf{x = 5.1}[/tex]

The values of [tex]\mathbf{x+5 = 10}[/tex] and [tex]\mathbf{1 = 10(x - 5)}[/tex] are not the same

Hence, [tex]\mathbf{x+5 = 10}[/tex] and [tex]\mathbf{1 = 10(x - 5)}[/tex] are not equivalent

Answer:

h = 16.7 inches

Step-by-step explanation:

h² + (h + 7)² = 29²

h² + h² + 14h + 49 = 841

2h² + 14h - 792 = 0

h² + 7h - 396 = 0

quadratic formula

h = (-7 ±√(7² - 4(1)(-396))) / (2(1))

h = (-7 ± 40.4103) / 2

h = -23.705 which we ignore as negative length makes no sense

     (although 23.705 inches will turn out to be the width of our rectangle)

or

h = 16.705

There is at least one root, possibly more. This is coming from the intermediate value theorem.

Answer:

[tex]\frac{3}{2}[/tex]

First, it is going upwards from left to right so we know it'll be positive. Then we do the following:

[tex]\frac{rise}{run}=\frac{change.in.y}{change.in.x}=\frac{y_{2} -y_{1}}{x_{2} -x_{1}}=\frac{0--6}{4-0} =\frac{0+6}{4-0} =\frac{6}{4} =\frac{3}{2}[/tex]
