Basile [38]4 years ago
5 0

Answer: x = 14


Step-by-step explanation:

the whole triangle's area 180 so you would add up all the angles and 66+62+38= 166 and 180-166=14 so 14 would = x

Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give
Aloiza [94]

Answer:

y = 4e^2x - 3e^2  

Step-by-step explanation:

f(x) = e^{2x^2}

lets calculate the derivate of f using the chain rule:

f'(x) = e^{2x^2}* (2x^2)' = e^{2x^2}*4x = 4e^{2x^2}x

we have that f'(1) = 4e^2, hence the equation is

y = f(1) + f'(1) (x-1) = e^2 + 4e^2(x-1)

or, equivalently,

y = 4e^2x - 3e^2

In the figure, is an exterior angle to triangle .
ludmilkaskok [199]

Answer:

I don't have c but I do have a and b

Step-by-step explanation:

Part A)

Angle 3 is 103° because 77° + ∠3= 180° and  ∠3 = 180° - 77° = 103°

Part B)

Angle 4 is 77° because ∠3 + ∠4 = 180° and  ∠4 = 180° - 103° = 77°

                                    These are the answers for k12

What is the solution to<br> 7x-2=2(3x+4)-7
sergeinik [125]

Answer:

7x - 2 = 2(3x + 4) - 7

7x - 2 = 6x + 8 - 7

7x - 2 = 6x + 1

x - 2 = 1

x = 3

Is there's a multiple of 1/6 between 3/6 and 4/6?
irina [24]
Lets find that out writing equations and solving them, a multiple of 1/6 is something like this (1/6)x, so we have
(1/6)x > 3/6
and
<span>(1/6)y < 4/6
</span>lets solve both equations:
<span>(1/6)x > 3/6
</span>x > 6(3/6)
x > 3

<span>(1/6)y < 4/6
</span>y < 6(4/6)
y < 4

So the number must be between 3 and 4, which is obvious, lets try with 3.5 then, that is 3 5/10 or 35/10 = 7/2 in fractional form, and lets try it out:
(1/6)(7/2) = 7/12
finally we compare with the original fractions:
1/6 < 7/12
2/12 < 7/12
So, it comply with being greater than 1/6, now lets compare with 4/6
7/12 < 4/6
<span>7/12 < 8/12
</span>therefore is also smaller than 4/6 and hence 7/12 is a multiple of 1/6 between 3/6 and 4/6
