Count the ratios together
4+3+5=12

Now multiply the $480 into the ratios over the total ratios

4/12 x 480= $160

3/12 x 480= $120

5/12 x 480=$200

4 : 3 : 5
$180:$120:$200

Sally is making a scale drawing of her apartment.

Studentka2010 [4]

The answer is B
We know that 1 1/2 is 12 foot
So we divide it by 2 so we know every 6 feet how long is it so we will get 0.75 for each 6 feet.
Now we divide 18ft by 3. We will have three sixs
Now multiple 0.75 by 3 = 2.25 which means the answer is B
And I attached a photo down so that helps more.

..vertex: (4, -1)<br> f(3) = -6

s344n2d4d5 [400]

Answer:

$\huge\boxed{f(x)=-5(x-4)^2-1=-5x^2+40x-81}$

Step-by-step explanation:

The vertex form of an equation of a parabola:

$f(x)=a(x-h)^2+k$

$(h;\ k)$ - vertex

We have

vertex $(4;\ -1)\to h=4;\ k=-1$

$f(3)=-6$

Therefore we have:

$f(x)=a(x-4)^2+(-1)=a(x-4)^2-1$

Substitute $x=3$ and $f(3)=-6$

$a(3-4)^2-1=-6\qquad|\text{add 1 to both sides}\\\\a(-1)^2=-6+1\\\\a(1)=-5\\\\a=-5$

Finally:

$f(x)=-5(x-4)^2-1=-5(x^2-2(x)(4)+4^2)-1\\\\=-5(x^2-8x+16)-1=-5x^2+(-5)(-8x)+(-5)(16)-1\\\\=-5x^2+40x-80-1=-5x^2+40x-81$

Q # 5 please find the area

ser-zykov [4K]

The Area of a Trapezoid can be calculated as:

Area = 0.5 x Height x Sum of lengths of parallel sides

From the figure, we can see the height, which is the perpendicular distance between two parallel sides is 12.6 inches.

The lengths of parallel sides is 19 and 29.2 inches.

Using the values in the above formula, we get:

Area = 0.5 x 12.6 x (19 + 29.2) = 303.66 square inches

So, the correct answer is option C
