Step-by-step explanation:

Here, 

 

Triangle ADC and triangle ABD are similar triangle as they are similar by A.A.A axiom.

now, as they are similar their sides are proportional to eachother, 

CD/BD : AB/AC : AD/AD

4.3/4 : AB/5.6 : AD/AD.

Taking 1st and srcond ratios we get,

4.3/4=AB/5.6

or, 4AB = 5.6×4.3 (cross multiplication)

Therefore, the measure of AB is 6.02 or 6.

Hope it helps...

write the standard form of the equation of the circle with endpoints of a diameter at the points (9,2) and (-7,5)

AnnyKZ [126]

Answer:

Step-by-step explanation:

Answer:

(x-1)²+(y-3.5)² = 265/4

Step-by-step explanation:

first find the midpoint (center of the circle)

(9+-7)/2, (2+5)/2

(1, 3.5) = center

then distance formula to find diameter

√(9- -7)²+(2-5)²=√256+9 = √265

The radius is half the diameter = (√265)/2

Formula for circle is (x-h)²+(y-k)²=r², where (h, k) is the center

Now you can plug everything in.

(x-1)²+(y-3.5)² = 265/4

How can I get -1 with theses answers

LiRa [457]

You can't get negative 1 from any equation shown in this picture. By the way, -5 +(-9) is not negative 4, it is negative 14,because according to PEMDAS( or BODMAS/BIDMAS/BEDMAS ), parenthesis goes first, so it's kinda like
(-9) + -5 instead.
