Find a, d, e on a triangle.
DiKsa [7]

Answer:

A=20 degrees

D=70 degrees

E=110 degrees

Step-by-step explanation:

A=20 because a right angle always = 90 so 90-70=20

D=70 because I believe that angles C and D make a right angle, and C = 20 degrees, so we now subtract. 90-20=70

E=110 because D and E = a straight line, which is 180, and sense D is 70 degrees, all we need to do is subtract. 180-70 is 110, so our answer is 110

Hoped this helped, and let me know if I messed up somewhere.

Step-by-step explanation:

The formula for slope is:

(y₂-y₁)/(x₂-x₁)

Now we plug in the coordinates given to us into the equation:

(5-(-10))/(-1-(-5))

Differentiating a Logarithmic Function in Exercise, find the derivative of the function. See Examples 1, 2, 3, and 4.
adoni [48]

Answer: The required derivative is \dfrac{8x^2+18x+9}{x(2x+3)^2}

Step-by-step explanation:

Since we have given that

y=\ln[x(2x+3)^2]

Differentiating log function w.r.t. x, we get that

\dfrac{dy}{dx}=\dfrac{1}{[x(2x+3)^2]}\times [x'(2x+3)^2+(2x+3)^2'x]\\\\\dfrac{dy}{dx}=\dfrac{1}{[x(2x+3)^2]}\times [(2x+3)^2+2x(2x+3)]\\\\\dfrac{dy}{dx}=\dfrac{4x^2+9+12x+4x^2+6x}{x(2x+3)^2}\\\\\dfrac{dy}{dx}=\dfrac{8x^2+18x+9}{x(2x+3)^2}

Hence, the required derivative is \dfrac{8x^2+18x+9}{x(2x+3)^2}

Just need the answer. it was "Check all that apply." at the end.
lianna [129]

Billy, let's recall what a linear pair of angles is:

• They are formed when two lines intersect.

,

• Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.

,

• The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Upon saying that we have that:

• CAD and DAE are linear pairs

,

• CAD and CAB are linear pairs

,

• DAE and BAE are linear pairs

,

• DAE and DAC are linear pairs

Now, you are ready to select all the options that actually apply.

If the radius of a circle is 15 then the diameter of the same circle is
Svetlanka [38]

30, radius is equal to half the diameter, so to get diameter from the radius, multiply the radius by two.
