Answer:

\text{The value of }(b^2-4ac)\thinspace is\thinspace 169

Step-by-step explanation:

Given the equation 5x^2 + 7x = 6

we have to find the value of b^2-4ac

Equation: 5x^2+7x-6=0

Comparing above with general quadratic equation ax^2+bx+c=0

we get, a=5, b=7 and c=-6

b^2-4ac=(7)^2-4(5)(-6)=49+120=169

Hence,

\text{The value of }(b^2-4ac)\thinspace is\thinspace 169

B²-4ac? 

<span>5x²+7x-6 = 0 </span>
<span>the form is ax²+bx+c = 0 </span>

<span>a=5, b=7, c=-6 </span>


<span>The discriminant D = b²-4ac </span>
<span>= 7² - 4(5)(-6) = 49 + 120 </span>
<span>= 169 </span>

Alex wants to sew a pillow in the shape below. How many square yards of fabric are needed to sew the pillow? Fabric is only sold
r-ruslan [8.4K]

The shape is missing, so i have attached it.

Answer:

2.6

Step-by-step explanation:

From the image attached, the diameter of the inner semi - circle is 0.5 yards while the length of each side of the pillow is 0.2 yards.

Thus, for us to find the length of the seam which is along the edges of the pillow, we will calculate the perimeter of the outer semicircle, then add the perimeter of the inner semicircle and also add the sides too.

Now, due to the fact that the length of the sides of the pillow are 0.2 yards each, the diameter of the outer circle would be;

0.5 + 0.2 + 0.2 = 0.9 yards. So, the perimeter of the outer semicircle is,

P0 = πd/2 = π × 0.9/2 =0.45π yds

The perimeter of the inner semicircle would be given as;

PI = πd/2 = π × 0.5/2 =0.25π yds.

Thus, we can calculate the total perimeter of the pillow as;

PT = P0 + PI + 0.2 + 0.2

PT = 0.45π + 0.25π + 0.2 + 0.2

PT ≈ 2.6 yards

Alex will need 2.6 yds
