Answer:
(B , D) = (-2,5)
Step-by-step explanation:
The given quadratic expression is
compare the given expression with
so we have
now and
we need to find two numbers such that their product is -30 and sum is -1
-6 and 5 are such numbers
so we have
grouping first two terms and last two terms
factor out 3x from first two terms and 5 from last two terms
( factor out (x-2))
hence B =-2 and D= 5
(B,D)= (-2,5)
Answer:
6
Step-by-step explanation:
Here, we are told to find the length of EB
Since the chords AB and CD are both 5 units(equidistant) away from the center of the circle, then we can conclude that they are both congruent and thus are equal in length
Now we use a circle theorem to solve for the length EB
The theorem is that a line that joins the center of a circle to a chord makes a perpendicular angle with the chord and splits the chord into 2 equal parts.
Now we can say that; AB = AE + EB so we split 12 into 2 which is 6 units and that is the length of EB
So in this problem we can state that each T-shirt costs S19 each. And if Kate buys two she gets a 30% off with the second shirt she buys. <span>And how much will she pay?
Solution:</span> <span><span>
1. </span>19 for each t-shirt</span> <span><span>
2. </span>Total of $38 if not provided with 30% off</span>
<span><span>3. </span>19 x 0.3 = 5.7</span>
<span><span>4. </span>Hence 30% of $19 is $5.7</span>
<span><span>5. </span>Next is we deduct $5.7 which is 30% of $19.</span> <span><span>
6. </span>19 – 5.7 = $13.3</span> <span><span>
7. </span>Therefore we add one shirt for $19 and the second, less 30% off which now only costs for $13.3.</span> <span><span>
8. </span>19 + 13.3 = 32.3</span>
<span><span>9. </span>Conclusively, she will pay $32.3 for the shirts.</span>
