Lubov Fominskaja [6]3 years ago

Answer:

Step-by-step explanation:

I'm not very familiar with 2 column proofs but the following is how we'd prove it in the UK:

AB ≅ AC  ( Given)

BE ≅ CE   (Given)

Line segment AE is common to Δ's ABE and ACE

so the 2 triangles are congruent.   (By SSS).

< BAD  ≅ < CAD ( as triangles ABE and ACE are congruent).

AD is common  to Δ's BAD and CAD.

AB  ≅ AC (given)

So Δ's BAD and CAD are congruent by SAS.

Therefore < ADB  ≅ < ADC ( as triangles BAD and CAD are congruent).

m < BDE = 180 - m < ADB  and

m < CDE = 180 - m < ADC  (both  angles are adjacent)

So since < ADB  ≅ < ADC,

< BDE    ≅ < CDE.

Find the perimeter of a towel thay measures 2 feet by 3/4 foot
levacccp [35]
A typical towel is the shape of a rectangle.
Rectangles have 2 opposite pairs of congruent (equal) sides.
To find perimeter, find the sums of all the sides.

The measures of the towel's sides are:
2 feet
2 feet
3/4 foot
3/4 foot

Add these together to find the perimeter.

2 + 2 + 0.75 + 0.75 = 5.5

The perimeter of the towel is 5.5 feet.

Hope this helps!

I need help with these two questions !
Gnesinka [82]
Problem 1

The portion from t = 0 to t = 5 represents going downhill, which is a total duration of 5 seconds. This is because the speed is going up (the y values are increasing) as you move from right to left for this interval. It looks like you're going uphill here, but keep in mind that the y axis is not position. Instead, the y axis represents speed. 

Answer: 5 seconds

============================================================

Problem 2

You have the correct table. Nice job. Don't forget to show your work if your teacher requires it.

============================================================

Problem 3

f(x) = x*|-2|^x
f(3) = 3*|-2|^3 ... replace every x with 3
f(3) = 3*(2)^3
f(3) = 3*8
f(3) = 24

The input is x = 3 which leads to the output y = 24
The ordered pair (x,y) = (3,24) is on the function curve

Answer: 24
