Given that f(x) = x2 + 8x – 5 and b = f(4), what is the value of -b? (Use only the digits 0-9 and the negative sign if necessary to enter the value.)

Answers

Answer 1
Plug in 4 for x
f(4) = 4^2 + 8(4) - 5
f(4) = 16 + 32 - 5 = 43
B = 43, so -B = -43

Solution: -43

Step-by-step explanation:

slope is simply the rise over the run which is the change in y over the change in x.

( (y_2) - (y_1) ) / ( (x_2) - (x_1) )

if you plug in your variables that gives you

Jose is 52 inches tall and is growing 0.25 inches each month. Jacob is 54 inches tall and is growing 0.1 inches each month. How many months, x, will it take for Jose to be the same height as Jacob?

Answers

Answer:

who measures someone's height in inches

Step-by-step explanation:

the answer is 14

It will take 13.3 months for Jose to be the same height with Jacob.

x = number of month

The height equation for Jose:

Jose is already 52 inches tall and growing at 0.25 inches per month. Therefore, his height is represented as follows

h(x) = 52 + 0.25(x)

The height equation for Jacob:

Jacob is already 54 inches tall and growing at 0.1 inches per month. Therefore, his height is represented as follows

h(x) = 54 + 0.1x

For both to have the same height,

52 + 0.25x = 54 + 0.1x

52 - 54 = 0.1x - 0.25x

-2 = -0.15x

x = -2 / -0.15

x = 13.3333333333

x = 13.3 months

What is the Nth term rule of the Quadratic sequence -5 -4 -1 4 11 20 31

Answers

Step-by-step explanation:

an = A×n² + B×n + C

a1 = -5 = A×1² + B×1 + C = A + B + C

a2 = -4 = A×2² + B×2 + C = 4A + 2B + C

a3 = -1 = A×3² + B×3 + C = 9A + 3B + C

a2 - a1 = -4 - -5 = 1 = 4A+2B+C-A-B-C = 3A + B

3A = 1 - B

A = (1 - B)/3

a3 - a2 = -1 - -4 = 3 = 9A+3B+C-4A-2B-C = 5A + B

3 = 5A + B = 5(1 - B)/3 + B

9 = 5(1 - B) + 3B = 5 - 5B + 3B = 5 - 2B

4 = -2B

B = -4/2 = -2

A = (1 - -2)/3 = (1 + 2)/3 = 3 / 3 = 1

-5 = A+B+C = 1 - 2 + C = -1 + C

-4 = C

so,

an = n² - 2n - 4

The first recorded Olympic game began in 776 called the Asian Olympics games were held every four hours until being abolished by the Roman emperor Theodosius in 393 determine the length of time between the start of the ancient Olympics and the modern Olympics which began in 1896

Answers

Answer:

1503 years

Step-by-step explanation:

Although the ancient Games were staged in Olympia, Greece, from 776 BC through 393 AD, it took 1503 years for the Olympics to return. The first modern Olympics were held in Athens, Greece, in 1896.

a.Donkey Kong is an arcade game where an animated figure, Mario, jumps over barrels. In the original game, it was virtually impossible to get through to Level 22 before Mario was ‘killed’ by the game. This was an unintended consequence of how the number of bonus points was calculated and stored.

The number of bonus points a player starts with when they move onto a new level depends on the number of the level that they are moving onto. Behind the scenes, Donkey Kong takes the level that is about to be entered, multiplies it by 10 and adds 40, thus yielding the first two digits of the player’s starting bonus.

So, for example, if a player is about to start Level 2, the bonus number is calculated like this:

2 × 10 + 40 = 60.

This bonus number is stored in a single byte as an unsigned integer. The bonus number will never be 0.

i.Write down and evaluate an expression for the number of different unsigned integers that can be represented in a single byte. Then write down the largest unsigned integer that can be represented if no representation for 0 is required.
ii.Find the bonus number associated with Level 22. Explain why storing this bonus number will cause a problem.
iii.For Level 22, the bonus number actually stored is 4. Give one likely explanation for this.
iv.The bonus number is multiplied by 100 before it is displayed on the screen, so for Level 22 the number displayed on the screen is 400. The displayed number decreases by 100 every 1.75 seconds. When the displayed number reaches 0, Mario is automatically killed. How many seconds does the player have to finish Level 22?

Find the angles of a triangle which are in the ratio 4:3:2.​

Answers

Answer:

80o, 60o, 40o

Step-by-step explanation:

The sum has to add up to 180 degrees because of the three sides and this is what matches.

Answer:

Let the given angles of the triangle be 4x, 3x and 2x.

We know that the sum of all interior angles of a triangle is 180°.

Therefore,

4x+3x+2x = 1809x = 180x = 180/9x = 20

Hence, the angles of the triangle are -

4x = 4×20 = 80°3x = 3×20 = 60°2x = 2×20 = 40°
