Answer:

a31 = -334

Step-by-step explanation:

Given:

a1 = 26

a22 = -226

Find:

a31

Computation:

a22 = a + 21d

-226 = 26 + 21d

d = -12

a31 = a + 30d

a31 = 26 + 30(-12)

a31 = 26 - 360

a31 = -334

a1 = 26 and a22 = −226.

Answer:

A)  −334

Answer:

If a is positive and b is greater than 1 , then it is exponential growth. If a is positive and b is less than 1 but greater than 0 , then it is exponential decay

Answer:

x<20

Step-by-step explanation:

Building linear functions for each situation, the inequality is:

[tex]18x + 100 < 15x + 160[/tex]

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

Choice A:

Thus, the cost of inviting x guests is given by:

[tex]C_a(x) = 18x + 100[/tex]

Choice B:

Thus, the cost of inviting x guests is given by:

[tex]C_b(x) = 15x + 160[/tex]

A cost less than B, thus, the inequality is:

[tex]C_a(x) < C_b(x)[/tex]

[tex]18x + 100 < 15x + 160[/tex]

Step-by-step explanation:

P = 8

Step-by-step explanation:

Given that P varies inversely with x then the equation relating them is

P = \frac{k}{x} ← k is the constant of variation

To find k use the condition P = 7 when x = 8 , then

7 = \frac{k}{8} ( multiply both sides by 8 )

56 = k

P = \frac{56}{x} ← equation of variation

When x = 7 , then

P = \frac{56}{7} = 8

Answer:

  (x +3)(x +1)(x -2)

Step-by-step explanation:

A graphing calculator is a good tool for finding factors fast. Each zero (p) gives rise to a factor (x -p).

The graph shows zeros at -3, -1, and 2, so your factorization is ...

  (x +3)(x +1)(x -2)

Answer: The walking path around it.

Step-by-step explanation:

Remember the Pythagorean's theorem, for a triangle rectangle with catheti A and B, and with hypotenuse H, we have:

A^2 + B^2 = H^2

or

H = √(A^2 + B^2)

Here, A + B is the total distance for the path, while the hypotenuse is the distance for the bridge

Here we can see that:

A = 1170 ft

B = 520 ft

Then:

H = √( (520 ft)^2 + (1170 ft)^2) = 1280.4 ft

Now, let's compute the costs.

For the bridge, we know that each foot costs $11, then for 1280.4 ft the cost is:

Cost of the bridge = (1280.4)*$11 = $14,084.4

And for the walking path, the cost is $6 per foot, then the total cost of the path is:

Cost of the path = (520 ft + 1170 ft)*$6 = $10,140

We know that the bridge is preferred if it is within the range of $1500 for the path's cost.

This range is:

($10,140 - $1,500, $10,140 + $1,500) = ($8,640, $11,640)

Here we can see that the cost of the bridge does not belong to this range, (is higher) so the option we should recommend is the walking path around.

Answer:

18

Step-by-step explanation:

30 + 18 = 48

30 - 18 = 12

Both true, so our solution is correct.

The value of the larger number is 30 and the value of the smaller number is 18.

A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.

Given that the sum of two numbers is 48. if the smaller number is subtracted from the larger the difference is 12. The two numbers will be calculated as,

x + y = 48

x - y = 12

________

2x = 60

x = 30

y = 30 - 12

y = 18

Therefore, the value of the larger number is 30 and the value of the smaller number is 18.

Answer:

Step-by-step explanation:

sin(D) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

         = [tex]\frac{7}{14}[/tex]

         = [tex]\frac{1}{2}[/tex]

         = 0.5

cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

          = [tex]\frac{12.124}{14}[/tex]

          = 0.866

tanD = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

        = [tex]\frac{7}{12.124}[/tex]

        = 0.577

Since, sinE = cosD

Therefore, sinE = 0.866

Since, cosE = sinD

Therefore, cosE = 0.5

Since, tanE = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

                   = [tex]\frac{12.124}{7}[/tex]
