PLEASE QUICK!!
valentina_108 [34]

Answer:

Step-by-step explanation:

So, when we dilate a triangle, it affects side measures.

So let's find it!

10*0.4=4

30*0.4=12

So, the sides of our new triangle is 4 and 12.

Let's find the area!

\frac{4*12}{2} =24

So, it is the first option! Hope this helps!

For the graph below, what should the domain be so that the function is at least 300? (1 point) graph of y equals minus 2 times t
alexandr1967 [171]

The function is a quadratic function, then the domain will be all real numbers. Then the correct option is D.

<h3>What are domain and range?</h3>

The domain means all the possible values of x and the range means all the possible values of y.

The function is given below.

y = -2x² + 50x + 300

Then the function is a quadratic function, then the domain will be all real numbers.

What area of the grass is being watered by this sprinkler
Novay_Z [31]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Use this formula:

Area of circle = \pi r^{2}

However, as we are using 3.14 for 'pi', we can write it like this:

Area = (3.14)r^{2}

'r' is the radius which is 12ft

Substitute this value into the equation:

Area = (3.14)12^{2}

Solve:

Area = 452.16

Multiply this value by 0.75 to get the answer:

452.16 x 0.75 = 339.12

339.12 square feet is being watered

<h3><u>✽</u></h3>

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
