Pretzel King Pretzels sells a jumbo box full of pretzel rods. Each box is 10inches by 10inches by 8in. Each pretzel rod is appro

andrew11 [14]

First solve the volume of the box
V = 10 x 10 x 8 = 800 cubic inches
Then solve the volume of 1 pretzel
V = pI*h*r^2
V = 3.14*5*(0.25)^2
V = 0.98125 cu. In
So the amount of pretzel can be pack
<span>A = 800/ 0.98125 = 815 pretzel</span>

| Find the quadratic polynomial whose<br> Sum and products of zeros are 21/8 and 5/16

tatuchka [14]

Answer:

$16x^{2} -42x+5$

Step-by-step explanation:

Sum of its zeroes= $\alpha +\beta =\frac{21}{8} \\$

Product of its zeroes= $\alpha \beta$ = $\frac{5}{16}$

Formula to form a quadratic polynomial:

$p(x)=k[x^{2} -(\alpha +\beta )x+\alpha \beta ]$

p(x)= $k[x^{2} -(\frac{21}{8} )x+\frac{5}{16}]$

p(x)= $16[x^{2} -(\frac{21}{8} )x+\frac{5}{16}]$

p(x)= $[16x^{2} -42x+5]$

The quadratic polyniomial is $16x^{2}-42x+5$
