Given f(x) = x^2 – 5x + k, and the remainder when f(x) is
divided by x - 7 is 34, then what is the value of k?

Answers

Answer 1

Step-by-step explanation:

f(7) = 34

7² -5(7) +k = 34

49-35+k =34

14+k = 34

k = 34-14

k = 20

Answer 2

Step-by-step explanation:

f(7) = 34

7² -5(7) +k = 34

49-35+k =34

14+k =34

k = 34-14

k = 20

hope it's help

What would be the range of possible whole number values (x) for a 3rd side of the triangle with two sides of 5 in. and 8 in.?

& Name one possible value for a third side?

Correct Answer Only

Answers

Answer:

Range of the third side of a triangle

Step-by-step explanation:

Any one side of a triangle must be shorter than the sum of the other two sides. Therefore, the third side length x must be between 5 and 35, not including those endpoints: 5 < x < 35. All whole numbers satisfying this range would form a triangle.

20 is a possible value for a third side

if a quadratic equation with real coefficients has a discriminant of -2, then its roots must be

A:2 real
B:1 real
C: imaginary
D:equal​

Answers

The correct answer is C: imaginary.

When the discriminant is negative, this implies that the quadratic equation has no roots (or zeros) in the set of real numbers. The roots belong to the set of complex numbers, and will be called "complex roots" (or "imaginary roots").

Therefore, the correct answer is C: imaginary.

Tom buys a boat from a friend, and will pay his friend the same amount of money each year until the boat is paid for. The following graph gibes the amount of money, in dollars, Tom owes his friend, as a function of the amount of time, in years.

Answers

The graph of amount Tom owes his friend after a given time, t, is a straight line graph with a negative slope

Please find attached the required example of a possible graph that shows the amount Tom owes his friend

Reason:

Let A represent the amount of money Tom buys the boat with, let x

represent the amount of equal payment made and y represents the

amount Tom owes the friend after a given time, t, we have;

y = A - x·t

Therefore, the slope of the graph formed is -x, the y-intercept of the graph

is A, from which the graph that gives the amount of money, in dollars, Tom

owes his friend, as a function of time, in years can be presented as follows,

using example values;

A = $25,000 (Amount the Tom agrees to buy the boat)

x = $5,000 (Amount Tom pays each year for the boat)

By plugging in the above example values, the attached graph can be drawn using MS Excel

  (c)  y = 3x +2

Step-by-step explanation:

The second given point is the y-intercept, telling you that the 'b' in the equation y = mx +b is 2. This eliminates the first and last choices.

Trying the other point in the two remaining equations shows you which one works:

  (b)  y = -3x +2

     -1 = -3(-1) +2 . . . . not true

  (c)  y = 3x +2

     -1 = 3(-1) +2 . . . . true

The equation of the line through the two points is ...

  y = 3x +2

_____

Additional comment

If you plot the two points, you see the line connecting them must have a positive slope. Only the third choice has a positive slope and a y-intercept of 2.

Austin, Kevin and Lisa have a total of $159. Austin has $11 more than Kevin. Lisa has twice as much money as
Keyin. How much money does Lisa have?

Answers

Answer:

Step-by-step explanation:

A+K+L=159

A-K=11

2K=L

Plug in 2K instead of L in the equation: A+K+L=159

A+3K=159

Plug in K+11 instead of A in the equation: A+3K=159

4K+11=159

4K=148

Kevin=$37

Pluge in 37 instead of K in the equation: A-K=11

A-37=11

Austin=$48

Plug in 48 instead of A and 37 instead of K in the equation: A+K+L=159

48+37+L=159

L=74

2⅒

Step-by-step explanation:

0.1 = 1/10

2 ⅒

Answer:

2 1/10

Step-by-step explanation:

To convert the decimal 2.1 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

2.1 = 2.1

     --------    

         1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

= (2.1 × 10)

    (1 × 10)              = 21

                             ------

                               10

Now you have to simplify, 2 1/10.
