A trapezoid has a base of two and six and an area of 24 square units. What is the height?

1 answer:

8 0

$\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} a,b=&\stackrel{bases}{parallel}\\ &sides\\ h=&height\\ \cline{1-2} a=&2\\ b=&6\\ A=&24 \end{cases}\implies 24=\cfrac{h(2+6)}{2}\implies 24=\cfrac{h(8)}{2} \\\\\\ 24=4h\implies \cfrac{24}{4}=h\implies 6=h$

Find the image of each polygon with the given vertices after a dilation centered at the origin with the given scale factor. J(2,

MAVERICK [17]

Applying a dilation centered at the origin with scale factor $k$ has the effect of multiplying both coordinates of a point by $k$ :

$(x,y)\mapsto (kx,ky)$

So, in your case, the coordinates of the points double:

$J'=(4,8),\quad K'=(8,8),\quad P'=(6,4)$

Round to the nearest hundredth 26.9816

VARVARA [1.3K]

$\huge{\boxed{26.98}}$

The hundredths place is the second place after the decimal point. In this case, it is $8$ .

We can round it by looking at the next place to the right, which is a $1$ . $1$ is less than $5$ , so we can just cut off everything after the hundredths place. This leaves an answer of $\boxed{26.98}$ .
