Step-by-step explanation:

week 1 - 62,68,68,68,69,70,70,72,72,75,75,76,78,78,80,80,80,89,89

week 2 - 62,68,68,68,69,70,70,72,72,72,75,75,76,78,78,80,80,80,85,86,86,86,88,88, 88,88,89,89,89,89

(bold = median)

week 2 median = 79 > week 1 median = 75

A cylinder has radius R = 3.7 and height H = 5.6 both measured in inches. What is the volume of this cylinder measured in cm3? (

lorasvet [3.4K]

Answer:

<h2>The volume is $3946.17cm^3$ </h2>

Step-by-step explanation:

We need to convert the radius and the height to cm first

1 cm = 0.393701 in

r (cm)= 3.7 in

$h(cm)= \frac{3.7}{0.393701}= 9.398 cm$

1 cm = 0.393701 in

h (cm)= 5.6 in

$h(cm)= \frac{5.6}{0.393701}= 14.22 cm$

The formula the volume of cylinder is

$volume= \pi r^2h\\\\volume= 3.142*9.398^2*14.22\\volume=3946.17cm^3$

A train ticket was £4.50. The price then increased by 3%. What price is the train ticket now

mihalych1998 [28]

0.14 pounds (rounded; 0.135 unrounded); To calculate the % of something, divide it by 100 and multiply the result by the percentage you want to find.

0.0450 (=1%)

0.0450 x 3 = 0.135

Factor completely −5x2 + 10x − 15. −5(x2 − 2x + 3) −1(x2 − 10x + 15) −5x(x2 − 2x + 3) −5(x2 − 2x − 3)

Luba_88 [7]

Answer:

-5(x² -2x +3)

Step-by-step explanation:

5 is a factor common to all of the coefficients. It is convenient to have the x² coefficient be positive in the factored form, so the result of factoring out -5 is ...

... -5((-5x²/-5) +(10x/-5) +(-15/-5)) = -5(x² -2x +3)

How do I solve quadratic equations for example,h(t) = – 0.07t2 + 0.007t + 5

g100num [7]

Answer:

x ≈ -8.402, 8.502

Step-by-step explanation:

The usual methods of solving quadratic equations apply to this one. Any of them can be used: graphing, factoring, completing the square, quadratic formula.

<h3>Solution</h3>

Often, when the coefficients are non-integers and have no obvious relationship to each other, the most convenient method of solution is the quadratic formula. It tells you the solution to ax²+bx+c=0 is ...

$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

Your equation has the coefficients, a = -0.07, b = 0.007, c = 5, so the solutions are ...

$x=\dfrac{-0.007\pm\sqrt{0.007^2-4(-0.07)(5)}}{2(-0.07)}=\dfrac{-0.007\pm\sqrt{1.400049}}{-0.14}\\\\x=0.05\pm\sqrt{\dfrac{200007}{2800}}=0.05\pm\sqrt{71.4310\overline{714285}}\\\\\boxed{x\approx\{-8.40169,\,8.50169\}}$
