This set of points are connected to form a line segment. What is its length? A = (3,5) and B = (3,6) *

Colt1911 [192]

Answer:

d(A,B)=1

Step-by-step explanation:

To find distance between points A(xA,yA) and B(xB,yB), we use formula:

d(A,B)=(xB−xA)2+(yB−yA)2−−−−−−−−−−−−−−−−−−−√

In this example: xA=3 , yA=5 , xB=3 and yB=6 so:

d(A,B)d(A,B)d(A,B)=(3−3)2+(6−5)2−−−−−−−−−−−−−−−√=0+1−−−−√=1

Given: AG and CI are common internal tangents of H and B. HG = 7, ED = 7, and ED = EF.

RideAnS [48]

EC = 24

This is because CBE is a right triangle with a right angle at angle ECB. Then we know that BC =7 and EB = 25. Use the Pythagorean Theorem to find EC.

Name two integers whose product is negative.

oksano4ka [1.4K]

You know that one integer is a negative integer, as the product is negative- and if the sum is zero, then the absolute value of the two integers are equal. Thus, the integers are +/- sqrt(36). or +/- 6.

Example: 6 and -6

Your welcome.

What is the solution to the inequality 5.25 – b ≥ 6.5? A number line going from negative 5 to positive 5. A solid circle appears

Reil [10]

Given:

The inequality is

$5.25-b\geq 6.5$

To find:

The solution of the given inequality on the number line.

Solution:

We have,

$5.25-b\geq 6.5$

Subtract 5.25 from both sides.

$5.25-b-5.25\geq 6.5-5.25$

$-b\geq 1.25$

Multiply both sides by -1 and change the sign of inequality.

$b\leq -1.25$

The value of b always less than or equal to -1.25. Since -1.25 included in the solution set, therefore there is a solid circle on -1.25.

-1.25 lies between -2 and -1. It means the solid circle lies between -1 and -2.

$b\leq -1.25$ , so the number line is shaded from the circle to negative 5.

A number line going from negative 5 to positive 5 is the required solution if a solid circle appears between negative 1 and negative 2. The number line is shaded from the circle to negative 5.

Therefore, the correct option is A.
