PLEASE HELP!!!!!!!dgbdgdbhdndcn

Problem 1)

AC is only perpendicular to EF if angle ADE is 90 degrees

(angle ADE) + (angle DAE) + (angle AED) = 180
(angle ADE) + (44) + (48) = 180
(angle ADE) + 92 = 180
(angle ADE) + 92 - 92 = 180 - 92
angle ADE  = 88

Since angle ADE is actually 88 degrees, we do NOT have a right angle so we do NOT have a right triangle

Triangle AED is acute (all 3 angles are less than 90 degrees)

So because angle ADE is NOT 90 degrees, this means AC is NOT perpendicular to EF

-------------------------------------------------------------

Problem 2)

a) The center is (2,-3) 

The center is (h,k) and we can see that h = 2 and k = -3. It might help to write (x-2)^2+(y+3)^2 = 9 into (x-2)^2+(y-(-3))^2 = 3^3 then compare it to (x-h)^2 + (y-k)^2 = r^2

---------------------

b) The radius is 3 and the diameter is 6

From part a), we have (x-2)^2+(y-(-3))^2 = 3^3 matching (x-h)^2 + (y-k)^2 = r^2

where
h = 2
k = -3
r = 3

so, radius = r = 3
diameter = d = 2*r = 2*3 = 6

---------------------

c) The graph is shown in the image attachment. It is a circle with center point C = (2,-3) and radius r = 3.

Some points on the circle are

A = (2, 0)
B = (5, -3)
D = (2, -6)
E = (-1, -3)

Note how the distance from the center C to some point on the circle, say point B, is 3 units. In other words segment BC = 3.

tony spent $60.54 and bought 3 packs of notebooks and a calculator. how much does a pack of notebooks cost if a calculator costs
Amiraneli [1.4K]
First you need to find out the remaining value after he bought the calculator this would be 14.67.

60.54 - 45.87= 14.67

Next youll assume the packs of notebooks all cost the same and divide by 3

14.67 / 3 = 4.89

He spent 4.89 on one pack of notebooks

What is the solution of the system of equations? y=-4x+10 y=-2x-6
Elina [12.6K]

Question-


What is the solution of the system of equations? y=-4x+10 y=-2x-6


Answer-


y = -4x + 10

y = -2x - 6


-4x + 10 = -2x - 6

-4x + 2x = -6 - 10

-2x = -16

x = -16/-2

x = 8


y = -4x + 10

y = -4(8) + 10

y = -32 + 10

y = -22


solution is (8,-22)


Hope i helped have a wonderful day

Integrate (1-x³)² with respect to x​
Tasya [4]

Answer:

Start off by expanding the square:

x^6 -2x³ + 1.

Now, we can integrate it in dx:

∫x^6 - 2x^3 + 1 dx = ∫x^6 dx - 2∫x^3 dx + ∫1 dx = (x^7)/7 - 2((x^4)/4) + x = (x^7)/7 - (x^4)/2 + x.

That's the result!
