Answer:
$4.99 for each pair of socks.
1. y = 2(3)^x
2. 2 is the vertical stretch or compression
3. 3 is the base of the exponent
Area of parallelogram= base x height
218.7= 6.75 x height
height= 218.7÷6.75
height= 32.4
Answer:
<h3>1/4 and -1</h3>
Step-by-step explanation:
For a quadratic equation to have 2 equal root, the discriminant value must be equal to zero.
Discriminant D = b² - 4ac = 0
Given the equation
x^2 − 2(2k + 1)x + (k + 2) = 0
From the equation, a = 1, b = -2(2k+1), c = k+2
a = 1, b = -4k - 2, c = k+2
Substitute into the discriminant formula;
Recall that: b² - 4ac = 0
(-4k - 2)²-4(1)(k+2) = 0
16k²+16k + 4 - 4k - 8 =0
16k²+12k - 4 = 0
16k²+16k - 4k - 4 = 0
16k(k+1)-4(k+1) = 0
16k - 4 = 0 and k+1 = 0
16k = 4 and k = -1
k = 4/16 and k = -1
k = 1/4 and -1
<em>Hence the required value of k is 1/4 and -1</em>
