Figure VWYX is a kite.<br><br> What is the value of x?

Alecsey [184]

Answer:

$x=6\°$

Step-by-step explanation:

we know that

The sum of the internal angles of a kite is equal to $360\°$

In this problem we have

$90\°+90\°+(18x-2)\°+(12x+2)\°=360\°$

$(18x-2)\°+(12x+2)\°=360\°-180\°$

$30x=180\°$

$x=6\°$

Find the area of the region under the graph of f on [a, b].<br> f(x) = x2 − 8x + 17; [−1, 2]

Harman [31]

Answer:

The area is 42 area units.

Step-by-step explanation:

The area of a function f(x) on an interval [a,b] is given by:

$A = \int\limits^a_b {f(x)} \, dx$

Applying to this question:

$A = \int\limits^-1_2 {x^2 - 8x + 17} \, dx$

Then

$F(x) = \frac{x^{3}}{3} - 4x^{2} + 17x$

$A = F(2) - F(-1)$

$F(2) = frac{2^{3}}{3} - 4*2^{2} + 17*2 = \frac{8}{3} + 18 = \frac{8 + 3*18}{3} = \frac{62}[3}$

$F(-1) = frac{(-1)^{3}}{3} - 4*(-1)^{2} + 17*(-1) = -\frac{1}{3} - 21 = \frac{-1 - 21*3}{3} = -\frac{64}[3}$

$A = F(2) - F(-1) = \frac{62}[3} - (-\frac{64}[3}) = \frac{62+64}{3} = 42$

The area is 42 area units.

Line g passes through points (1, 1) and (10, 9). Line h is perpendicular to g. What is the

Sauron [17]

Answer:

$\bold{The~slope~of~line~h~is~-\frac{9}{8}. }$

Step-by-step explanation:

Hi there!

First, let's calculate the slope of line g.

$\displaystyle\frac{y2-y1}{x2-x1}$

$\displaystyle\frac{9-1}{10-1} \\
\displaystyle\frac{8}{9}$

So, the slope of line g is $\displaystyle\frac{8}{9}$

Now let's identify the slope of line h.

We are given that line h is perpendicular to line g.

Now, perpendicular lines have slopes that are opposite reciprocals.

This means we take a number, flop it over, and change its sign.

The slope of line g is

$\displaystyle\frac{8}{9}$

Now, we flop it over:

$\displaystyle\frac{9}{8}$

Then, we change its sign:

$\displaystyle-\frac{9}{8}$

Thus, $\displaystyle-\frac{9}{8}$ is our final answer.

Hope it helps! Enjoy your day! (:
