(A) use the Pythagorean theorean to determine the length of the unknown side of the triangle

Answers

Answer:

a. = 36km

b. Perimeter = 108km

c. Area = 486km^2

Step-by-step explanation:

Pythagoras theorem

a^2 + b^2 = c^2

27^2 + b^2 = 45^2

b^2 = 45^2 - 27^2

b^2 = 1296

b = [tex]\sqrt{1296}[/tex]

b = 36km

Perimeter

a + b + c

27 + 36 + 45 = 108

Perimeter = 108km

Area = [tex]\frac{ab}{2}[/tex]

Area = [tex]\frac{27 * 36}{2}[/tex]

Area = [tex]\frac{972}{2}[/tex]

Area = 486km^2

1. Find the coordinates of all points where the lines
x + y = 8, y = 5, and x = 1 intersect.

Answers

Answer:

(3)1. Find the coordinates of all points where the lines

x + y = 8, y = 5, and x = 1 intersect.

Step-by-step explanation:

this answer

The coordinates of all points where the lines x + y = 8, y = 5, and x = 1 intersect are (0, 5), (1, 0), (3, 5) and (1, 7).

Given that;

The equation of lines is,

x + y = 8

y = 5

x = 1

Now all the coordinates of all points where the lines x + y = 8, y = 5, and x = 1 intersect are find as,

x + y = 8

Put y = 5;

x + 5 = 8

x = 8 - 5

x = 3

Put x = 1;

1 + y = 8

y = 8 - 1

y = 7

Therefore, the points are (0, 5), (1, 0), (3, 5) and (1, 7).

Answers

the answer is 4160$

     After 6 years of investment of $3200 compounded continuously, final amount in the account will be $4319.55.

Moneysaver's Bank offers a saving account with the features as,

Rate of interest = 5% annualTime of investment = 6 yearsPrincipal amount = $3200

Expression to calculate the final amount when compounded continuously,

Final amount = [tex]P.e^{rt}[/tex]

Here, P = Principal amount

r = Rate of interest

t = Duration of investment

By substituting the values in the expression,

Final amount = [tex]3200.e^{0.05\times 6}[/tex]

                      = 3200(1.3498588)

                      = 4319.548

                      ≈ $4319.55

  Therefore, after 6 years of investment of $3200, final amount in the account will be $4319.55.

The sequence is geometric as common ratio is 1/2, each next term is half the previous one#2

a. 8, 16, 32, 64, ...

This is a geometric sequence as the common ratio is 2

b. 1, 1, 2, 3, 5, 8, ...

This is neither one since no common difference or ratio between the consecutive terms

c. 5, 5, 5, ...

This is neither one since common difference is zero or common ratio is 1

d. -101, -99, -97, -95, ...

This is a arithmetic sequence since the common ratio is 2#3

Use the quadratic function to predict y if x equals 6.

y = 2x2 − 2x − 2

A. y = 60

B. y = 58

C. y = −60

D. y = −58

Answers

Answer:

B. y = 58

Step-by-step explanation:

b) y=58 you follow the instructions

...............................................................................................................................................

The given quadratic function is      

y= 2x^2 - 2x - 2

We have to find the value of the function y at x=6.

Substitute x=6 in the given function.      

y= 2(6)^2 - 2(6) - 2

y= 2(36) - 12 - 2

y= 72 - 14

y= 58

The value of the function is 58 at x=6 is 58.

Therefore the correct option is B.
