Factorise 5x^2 - 34x + 24

Which set of ordered pairs represents a function?

Lana71 [14]

Answer:

{(-6,-6), (-2,-2), (7,-6), (-5,0)}

Step-by-step explanation:

Function: Every domain (x-value) has only one range (y-value)

The other choices had an x-value that had more than one y-value, which makes only this one a function.

Hope this helped :)

You have a distribution summarizing the number of days in the past two months (60 days) that an individual watched TV. The media

Scilla [17]

Given:
Data Set: 60 items
Median: 25
lower quartile or Q1: 21
upper quartile or Q3: 42

IQR = Q3 - Q1 = 42 - 21 = 21

The DISTRIBUTION IS SKEWED TO THE RIGHT.

distance between median and Q1: 25 - 21 = 4
distance between Q3 and median: 42 - 25 = 17

Since the distance between Q3 and median is greater than the distance between the median and Q1, the distribution is skewed to the right.

John wants to measure the width of a stream using the methods he has learned in geometry. He puts a stake in the ground opposite

otez555 [7]

John's method to determine the width of the stream uses the knowledge

that the tangent of 60° is approximately 1.7.

The proper sequence John would use to find the width of the stream are;

Step 1; John drives a stake opposite the tree to establish a line between two points

Step 2; John uses a compass to walk away from the stakes at a right angle

Step 3; On the path John walks until he finds a line of sight to the tree that equals 60 degrees

Step 4; John drives a second stake in the ground

Step 5; John measures the the distance between the two stakes

Step 6; John multiplies the distance between the two stakes by 1.7 to find the distance.

Reasons:

The steps that can be used to measure the width of the stream are;

Step 1: Drive a stake opposite the tree on the other side of the stream.

Step 2: With the aid of a compass, walk at right angles to the line formed by the stake and the tree.

Step 3; Keep walking along the previous path till a point is reached where the angle formed between the line of site to the tree and the walk path is 60°.

Step 4; At the point where the line of sight to the tree is 60°, a second stake is driven in the ground.

Step 5; Measure the distance between the stakes that are placed in the ground.

Step 6; Given that by trigonometry, the ratio of the width of the stream to the distance between the two stakes is tan(60°) ≈ 1.7, multiply the distance between the two stakes by 1.7 to find the width of the stream.

$\displaystyle tan(60^{\circ}) = \mathbf{\frac{Width \ of \ stream}{Distance \ between \ stakes}}$

The possible question options are;

John measures the the distance between the two stakes

John uses a compass to walk away from the stakes at a right angle

John multiplies the distance between the two stakes by 1.7 to find the distance

John drives a second stake in the ground

On the path John walks until he finds a line of sight to the tree that equals 60 degrees

John drives a stake opposite the tree to establish a line between two points.

Factor the expression completely by first taking out a common factor 3x^2 + 27x + 24

Marina CMI [18]

Answer:

=3(x+8)(x+1)

Step-by-step explanation:

3(x^2+9x+8)

3(x^2+8x+1x+8)

3[(x^2+8x)+(1x+8)]

3[x(x+8)+1(x+8)]

=3(x+8)(x+1)

PLEASE HELP ME WITH THIS ILL MARK AS BRAINIEST

ExtremeBDS [4]

Please use "^" to indicate exponentiation:

f(x)=x^2+10x+35

Complete the square: f(x)=x^2+10x+25-25+35 = (x+5)^2 +10

or y-10=(x+5)^2, so the vertex is at (-5,10). h has the value -5.
