Answer:

X = 276°

Step-by-step explanation:

Divide X into x1 and x2

then then using the trick of co-interior angles, find the answer of x1 and x2 . then add x1 and x2

The answers will be:

(4, 5)
remain constant and increase
g(x) exceeds the value of f(x)

<h3>What is Slope and curve?</h3>

a) The slope of the curve g(x) roughly matches that of f(x) at about x=4. Above that point, the curve g(x) is steeper than f(x), so its average rate of change will exceed that of f(x). An appropriate choice of interval is (4, 5).

b) As x increases, the slope of f(x) remains constant (equal to 4). The slope of g(x) keeps increasing as x increases. An appropriate choice of rate of change descriptors is (remain constant and increase).

c) The curves are not shown in the problem statement for x = 8. The graph below shows that g(x) has already exceeded f(x) by x=7. It remains higher than f(x) for all values of x more than that. We can also evaluate the functions to see which is greater:

f(8) = 4·8 +3 = 35

g(8) = (5/3)^8 ≈ 59.54 . . . . this is greater than 35

g(8) > f(8)

d) Realizing that an exponential function with a base greater than 1 will have increasing slope throughout its domain, it seems reasonable to speculate that it will always eventually exceed any linear function (or any polynomial function, for that matter).

The vector wequalsaiplusbj is perpendicular to the line axplusbyequalsc and parallel to the line bxminusayequalsc. It is also tr

Likurg_2 [28]

Answer:

$\theta=45^{\circ}$

Step-by-step explanation:

We are given that the equation of lines

$x+\sqrt 3y=1$

$(1-\sqrt 3)x+(1+\sqrt 3)y=8$

According to question

The vector perpendicular to the lines is given by

$i+\sqrt 3j$ and $(1-\sqrt 3)i+(1+\sqrt 3)j$

Therefore, the angle between two vectors is given by

$cos\theta=\frac{a_1a_2+b_1b_2}{\sqrt{a^2_1+b^2_1}\sqrt{a^2_2+b^2_2}}$

Using the formula

$cos\theta=\frac{1(1-\sqrt 3)+\sqrt 3(1+\sqrt 3)}{2\times 2\sqrt 2}$

$cos\theta=\frac{1-\sqrt 3+\sqrt 3+3}{4\sqrt 2}=\frac{1}{\sqrt 2}$

$cos\theta=cos 45^{\circ}$

$\theta=45^{\circ}$

Hence, the acute angle between the lines is given by

$\theta=45^{\circ}$

Plz help i dont understand

Elina [12.6K]

You can search in google if you want for the "inscribed quadrilateral conjecture"

and if you want... I can give you a quick proof of it

hmmm in short, if you inscribe a quadrilateral polygon in a circle
it will have 4 angles

each pair of opposite angles, are "supplementary angles", or they add up to 180°

so.. that said in yours, R+P = 180 and Q+O = 180 as well

you only need Q

so $\bf \measuredangle Q+\measuredangle O=180\qquad 
\begin{cases}
\measuredangle Q=2x+4\\\\
\measuredangle O=2x
\end{cases}\implies (2x+4)+(2x)=180$

solve for "x"

how big is Q? well, 2x + 4 :)
