express x^2 - 8x + 5 in the form (x - a)^2 - b where a and b are integers

Answers

Answer:

x^2 -8x + 5 = (x-4)^2 - 11

Step-by-step explanation:

Here we want to write the given expression in the form

x^2-8x + 5 can be written as follows;

(x-4)^2 = x^2 - 8x + 16

All we have to do is to subtract 11

Thus, we have it that;

x^2-8x + 5 = (x-4)^2 - 11

I need points.

Nigel and Mia are searching for a treasure chest under water. The straight line distance between them is 100 meters.

A triangle has points Nigel, Mia, and Treasure Chest. The distance from Nigel to Mia is 100 meters. The angle between Treasure Chest, Nigel, and Mia is 65 degrees. The angle between Nigel, Mia, and Treasure Chest is 80 degrees.

Given the angles in the diagram, who is closer to the treasure chest and why?

Nigel is closer because his distance to the chest is opposite the larger angle.
Mia is closer because her distance to the chest is opposite the smaller angle.
Nigel is closer because his distance from the chest is 100 meters.
Mia is closer because her distance from the chest is 100 meters.

Answers

Mia is closer to the treasure chest because her distance to the chest is opposite the angle less than 80 degrees.

What is triangle?

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

The sum of two sides of a triangle is greater then the third side. Mathematically -

a + b > c

The longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.

Given is a triangle that has points Nigel, Mia, and Treasure Chest. The distance from Nigel to Mia is 100 meters. The angle between Treasure Chest, Nigel, and Mia is 65 degrees. The angle between Nigel, Mia, and Treasure Chest is 80 degrees.

Refer to the image attached.

It can be seen that Mia is closer to the treasure chest because her distance to the chest is opposite the angle less than 80 degrees. We can conclude this from the fact that the longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle

Therefore, Mia is closer to the treasure chest because her distance to the chest is opposite the angle less than 80 degrees.

Jack tossed a coin three times. Which tree diagram shows all the possible outcomes of the coin landing heads up or tails up?

Answers

Answer:

The top three that are first :)

Step-by-step explanation:

1. Captain Salamander has 3 pet frogs called Dorris, Borris and Morris. He weighs them to check they are the right weight. However, the frogs will only be weighed two at a time! Dorris and Borris weigh 12lbs altogether. Borris and Morris weigh 16lbs altogether. Dorris and Morris weigh 14lbs altogether. How much does each frog weigh?

Answers

Answer:

Their weights are:

Dorris = 5 lbs

Borris = 7 lbs

Morris = 9 lbs

Step-by-step explanation:

Let the weights of the frogs be:

Dorris = d

Borris = b

Morris = m

given:

d + b = 12 - - - (1)

b + m = 16 - - - (2)

d + m = 14 - - - (3)

from (3)

d + m = 14

m = 14 - d - - - (4)

putting the value of m into equation 2:

b + m = 16

b + (14 - d) = 16

b - d + 14 = 16

b - d = 16 - 14

b - d = 2

b = 2 + d - - - - (5)

putting the value of 'b' in equation 5 into equation (1)

d + b = 12 - - - (1)

where: b = 2 + d - - - (5)

∴ d + (2 + d ) = 12

d + d + 2 = 12

2d = 12 - 2

2d = 10

∴ d = 10 ÷ 2 = 5

d = 5

putting the value of 'd' into eqn (5)

b = 2 + d - - - - (5)

where d = 5

b = 2 + 5 = 7

b = 7 lbs

to find 'm', let us use eqn (3)

d + m = 14 - - - (3)

where d = 5

∴ 5 + m = 14

m = 14 - 5 = 9

m = 9 lbs

Therefore their weights are:

Dorris = 5 lbs

Borris = 7 lbs

Morris = 9 lbs

A bag contains 7 milk and 5 dark chocolates. A sweet is selected at random. What is the probability of choosing: P(milk) = P(not milk) =

Answers

Answer: P(7)=P(5)=12

Step-by-step explanation:

The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.

What is probability?

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

A sack contains 7 milk and 5 dim chocolates. A sweet is chosen indiscriminately.

The total number of the sweets will be given as,

Total events = 7 + 5 = 12

The probability of choosing milk will be given as,

P = (7/12)

P = 0.5833

The probability of choosing not to milk will be given as,

P = (5/12)

P = 0.4167

The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.

Answer:

(1/2(2x+14)-7) = 1x+7-7= x g(f(x))= 2(1/2x-7)+14= x-14+14= xWe have the result being two variables of linearity hence they are not inverses. In order to be inverses they should have had switched notations, ie: -x vs x

9514 1404 393

Answer:

A: (f∘g)(x) = x

B: (g∘f)(x) = x

C: the functions are inverses

Step-by-step explanation:

A: (f∘g)(x) = f(g(x)) = f(2x +14)

= 1/2(2x +14) -7 = x +7 -7 = x

(f∘g)(x) = x

B: (g∘f)(x) = g(f(x)) = g(1/2x -7)

= 2(1/2x -7) +14 = x -14 +14 = x

(g∘f)(x) = x

C: When a function is operated on by its inverse, then original argument value is restored. That is the case for functions f and g, so the two functions are inverses.
