mulch to cover a rectangular garden costs 48. mulch is needed to cover a larger, similar garden. the ratio of dimensions is 2:3.
d1i1m1o1n [39]
\bf \qquad \qquad \textit{ratio relations}
\\\\
\begin{array}{ccccllll}
&Sides&Area&Volume\\
&-----&-----&-----\\
\cfrac{\textit{similar shape}}{\textit{similar shape}}&\cfrac{s}{s}&\cfrac{s^2}{s^2}&\cfrac{s^3}{s^3}
\end{array} \\\\
-----------------------------\\\\
\cfrac{\textit{similar shape}}{\textit{similar shape}}\qquad \cfrac{s}{s}=\cfrac{\sqrt{s^2}}{\sqrt{s^2}}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\\\\
-------------------------------

\bf \cfrac{\stackrel{small}{garden}}{\stackrel{large}{garden}}\qquad \stackrel{sides~ratio}{\cfrac{2}{3}}\qquad \stackrel{\textit{area ratio}}{\cfrac{s^2}{s^2}}\implies \cfrac{2^2}{3^2}
\\\\\\
\cfrac{2^2}{3^2}=\cfrac{\stackrel{small~area~cost}{48}}{\stackrel{large~area~cost}{a}}\implies \cfrac{4}{9}=\cfrac{48}{a}\implies a=\cfrac{9\cdot 48}{4}

the ratio of the cost, is tandem to the ratio of the areas, because, to get the cost for the mulch, you have to first know how many square meters/feet have, and then you apply the cost evenly, now, the cost is just a factor, therefore, the ratio is retained.

Find the measure of angle x in the figure.
Ghella [55]

Answer:

x = 125°

Step-by-step explanation:

There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.

Total of angles

= (n - 2)•180°

Put in 7, because there are 7 angles.

= (7 - 2)•180°

= 5•180°

= 900°

So the total of the angles should be 900°. We know all of the angles except one.

900° = 123°+129°+128°+128°+132°+135°+ x

900° = 775° + x

Subtract 775.

125° = x

The missing angle is 125°.

If the parent function f(x) = x^2 is fatter translated 11 units to the left, then translated 5 units down, write the resulting f
olga55 [171]

Part A.

1.  If the parent function f(x) = x^2 is shrinked (looks more flattened out and fatter) with coefficient 0<k<1, then  its equation is f(x) = kx^2.

2. If the function f(x) = kx^2 is fatter translated 11 units to the left, then its equation becomes

f(x) =k(x+11)^2.

3. If the function  f(x) = k(x+11)^2 is  translated 5 units down, then its equation becomes

f(x) = k(x+11)^2-5 where 0<k<1.

Answer 1: correct choice is B.

Part B.

1.  If the parent function f(x) = x^2 is shrinked (looks more flattened out and fatter) with coefficient 0<k<1, then  its equation is f(x) = kx^2.

2. If the function f(x) = kx^2 is fatter translated 8 units to the right, then its equation becomes

f(x) =k(x-8)^2.

3. If the function  f(x) = k(x-8)^2 is  translated 1 unit down, then its equation becomes

f(x) = k(x-8)^2-1 where 0<k<1.

Answer 2: correct choice is A.
