Answer:

The correct answer is second option

3.2

Step-by-step explanation:

It is given that, Coordinates of triangle ABC,

A(0, 1), B(0, 2) and C(3, 2)

ΔABC ≅ ΔDEF

Therefore we can write, AB = DE, BC = EF and AC = DF

<u>To find the measure of DF</u>

DF = AC

(0, 1) C(3, 2)

By using distance formula,

AC = √[(3 - 0)² + ( (2 - 1)²]

= √(9 + 1) = 3.16≈ 3.2

BC= DF

B(0,2) , C(3,2)

d= (3-0)^2 + (2-2)^2
d= 9
Square root 9= 3

DF = 3
Hope this helps!

the vertex of this parabola is at (3,5). When the y-value is 6, the x-value is -1. What is the coefficient of the squared term i

otez555 [7]

Now, assuming is a vertical parabola, so the squared variable is the "x", let's do some checking.

$\bf \qquad \textit{parabola vertex form}\\\\
\begin{array}{llll}
\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\
x=a(y-{{ k}})^2+{{ h}}
\end{array} \qquad\qquad vertex\ ({{ h}},{{ k}})\\\\
-------------------------------\\\\
vertex
\begin{cases}
h=3\\
k=5
\end{cases}\implies y=a(x-3)^2+5
\\\\\\
\textit{we also know that }
\begin{cases}
y=6\\
x=-1
\end{cases}\implies 6=a(-1-3)^2+5
\\\\\\
1=a(-4)^2\implies 1=16a\implies \cfrac{1}{16}=a$

Ms.Wooldridge walks laps around her pool for exercise each day. She walks at a constant rate of 30 seconds per lap. It takes her

nasty-shy [4]

Answer: it will take her 58 minutes to walk one mile.

Step-by-step explanation:

She walks at a constant rate of 30 seconds per lap and it takes her 46 steps to walk one full lap. It means that she walks 46 steps in 30 seconds.

If each step is approximately 1 foot, it means that the number of feet that she walks in 30 seconds is 46 feet.

1 foot = 0.000189 miles

Therefore, 46 feet would be

46 × 0.00189 = 0.008694 miles

Therefore, if she she walks 0.008694 miles in 30 seconds,

The time it will take her to walk 1 mile would be

30/0.008694 = 3450.66 seconds

Converting to minutes, it becomes

3450.66/60 = 58 minutes
