Answer:

the distance between the points is about 9.2 units

Step-by-step explanation:

It is well you should not understand it. <em>No question is asked</em>.

The answer choices suggest you are to find the distance between the two points. There is only one choice in a reasonable range: 9.2 units.

Each point is more than 2 units from any axis, so 2 units is clearly not the answer. The size of the graph is much less than 81 units, so clearly that is not the answer.

The difference of coordinates in the x-direction is 6; in the y-direction the difference is 7 units. The distance between the points will be more than the longest of these (7) and less than about 1.5 times that (10.5). Only one choice is in this range: 9.2 units.

The Pythagorean theorem is used to calculate the distance between points. The distance is considered to be the hypotenuse of a right triangle with legs of lengths equal to the differences of coordinates. Here, that means the distance (d) is ...

d² = 6² + 7² = 36 +49 = 85

d = √85 ≈ 9.2 . . . . grid squares, or "units"

jamal bought 2 packs of stickers and 8 individual stickers. Use x to represent the number of stickers in a pack of stickers and

NeTakaya

Answer: Yes , the expression of the total stickers Jamal bought is equivalent to 2(x+4).

Step-by-step explanation:

Let x be the number of stickers in each pack.

Since, Jamal bought 2 packs of stickers and 8 individual stickers.

Therefore, the total number of stickers Jamal bought= $2\times x+8=2x+8$

If we factorize the above expression by taking 4 as common outside, we get

The Therefore, the total number of stickers Jamal bought= $2(x+4)$

Find JK if KF= 1 *No A-D options(write the answer)

marysya [2.9K]

Answer:

The length of JF = 3

Step-by-step explanation:

We know that the point of intersection of the Medians of a triangle is called the centroid of a triangle.

Thus,

For the given triangle ΔHIJ,

Point K is the centroid of the triangle.

We also know that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.

Also, each Median is split into two parts such that the longer part is 2 times the length of the smaller part.

In our case,

The median JF is split into two parts such that the longer part JK is 2 times the length of the smaller part KF.

In other words,

JF = KF + JK

Given KF = 1

Also, the longer part JK is 2 times the length of the smaller part KF.

i.e.

JK = 2 KF

JK = 2(1) ∵ KF = 1

JK = 2

Thus, substituting KF = 1 and JK = 2 in JF = KF + JK

JF = KF + JK

JF = 1 + 2

JF = 3

Therefore, the length of JF = 3

Jobisdone [24]

Answer:

c. The moming pH of the cheese tends to be higher when the daly Ngh temperature in the shop is cooler compared 10 when the duly high temperature is warmer

Daily high temperature and the pH of cheese are inversely related.When one variable increases, the other one decreases.

Step-by-step explanation:

When there is a negative correlation between two variables, it means when one variable increases, the other one decreases.A correlation of -0.64 means that the variable do not have a strong negative correlation because its less that -0.9. However, this correlation is not a weak negative correlation because the value is more that -0.1
