How many tenths are there in 9 4/5

2 answers:

6 0

To figure out tenths, first you need to convert the mixed number into a fraction so 9 and 4/5 becomes 45/5+4/5=49/5. Now you can convert this into tenths by multiplying both the numerator and denominator by 2, so then 49/5 becomes 98/10. So there are 98 tenths in the mixed number 9 and 4/5

Evaluate the line integral, where c is the given curve. c y3 ds,<br> c.x = t3, y = t, 0 ≤ t ≤ 4

vivado [14]

The path $C$ is parameterized by

$\mathbf r(t)=\langle x(t),y(t)\rangle=\langle t^3,t\rangle$

with $0\le t\le4$ .

We have

$\dfrac{\mathrm d\mathbf r}{\mathrm dt}=\langle3t^2,1\rangle$
$\left\|\dfrac{\mathrm d\mathbf r}{\mathrm dt}\right\|=\sqrt{9t^4+1}$

So the line integral is

$\displaystyle\int_Cy^3\,\mathrm dS=\int_{t=0}^{t=4}t^3\sqrt{9t^4+1}\,\mathrm dt$

Substitute $u=9t^4+1$ , so that $\mathrm du=36t^3\,\mathrm dt$ .

$=\displaystyle\frac1{36}\int_{u=1}^{u=2305}\sqrt u\,\mathrm du$
$=\dfrac{2305^{3/2}-1}{54}$
$\approx2049.31$

Carlos says there are a total of 6,000 hundreds in the number 6,000,000.<br> Is Carlos correct?

Hatshy [7]

We know that 1 hundred= 100= 1*10^2. Therefore, 6,000 hundreds is equal to:
6,000*(1*10^2)= 600,000

Because 600,000 ≠ 6,000,000, Carlos is wrong.

Hope this helps~

The zeros of a quadratic function are 6 and -4. Which of these choices could be the function?

geniusboy [140]

Answer:

Step-by-step explanation:

If x = a is a zero of f(x) then (x - a) is a factor of f(x)

Here the zeros are x = 6 and x = - 4 then the corresponding factors are

(x - 6) and (x - (- 4) ) , that is (x - 6) and (x + 4)

Then f(x) is the product of the factors

f(x) = a(x - 6)(x + 4) ( a is a multiplier )

If a = 1 , then

f(x) = (x - 6)(x + 4) ← is a possible choice → C

A circle has a diameter of 10 cm. What is the best approximation of its area? Use 3.14 for pi.....you need radius not diameter i

makvit [3.9K]

Answer:

If it has a diameter of 10, divide it by 2 to get Radius (5) because Area = πr²

Then you do r * π *r which would be 78.5. so C is your answer.
