Y = (x + 2)(x − 3)<br> Find the zero of the function
svet-max [94.6K]

Answer:

The zeros are {-2, 3}

Step-by-step explanation:

Set each of these factors equal to zero, in turn, set each factor = to 0 and solve the resulting equation for x:

x + 2 = 0 yields x = -2;

x - 3 = 0 yields x = 3

The zeros are {-2, 3}

Hill in the blank: Type your answer in the box and then clichWhat is the value of n?144eAnswer:
Inessa05 [86]
The correct answer is 95°.

To solve for n, you can start by finding the measures of the triangle's interior angles. Knowing that a straight line measures 180°, you can subtract the given values from 180° to find the measures of the respective supplementary interior angles. That would give you 59° (180-121) and 36° (180-144).

Now, knowing that the measure of all the interior angles of a triangle is also 180°, you can add the two interior angles you know (59+36) and subtract those from 180°. Doing so would give you the measure of the missing third angle, which is 85°.

Finally, because angle n is the supplementary angle of the missing angle from the previous step, simply subtract that angle's measure from 180° to find n°, which is 180-85 or 95°.

A dime is 1.25 mm thick. How many meters high would a stack of dimes worth $50 be?
Ira Lisetskai [31]
1.25mm x 50 = 62.5 mm  Now lets change mm to meters.   There are 1000 millimeters in a meter and we are only talking about 62.5 so we are not even at a single meter.  Answers B and C can be eliminated.
 
   meter    decimeter   centimeter    millimeter  (each one is ten times more or less than the previous one depending on where you start.
Since we are changing mm to m, we will get fewer.  Why - try grouping any small things  like 14 days - you get 2 weeks.   72 hours - you get 3 days.  Notice that the number gets lower.  14---->2   and 72------->3
So we can expect our number to get smaller.  The beauty of the metric system it that is based on 10 so it involves moving decimals and adding or subtracting zeros if needed.
 meter    dm     cm   mm
                               62.5
notice that it would take 3 "jumps" to the left to get it under the word meter.   That means our decimal has to move 3 jumps to the left too.  In order to do that we need to add a zero in front of the 6 in 62.5
<u>Correct answer is 0.0625 </u> which is none of the answers above - Notice that the decimal is 3 places left from where it was before (62.5).
