Answer:

12). Length in the actual will be 6.25x12=75 in

13). Length in the model will be 15/12=1.25 ft

14). depth in the actual will be 32x12=384 cm

15). Width in the actual will be 5.4x12=64.8 ft

16). Diameter in the model will be 21/12=1.75 cm

Step-by-step explanation:

Given table show relation between model and actual prototype.

It is given that the actual prototype is scaled by 12 of the model.

I.e. Model x 12 = Actual.

12).

For mattress,

Length in the model is 6.25 in.

Length in the actual will be 6.25x12=75 in

13).

For corvette,

Length in the actual is 15 ft

Length in the model will be 15/12=1.25 ft

14).

For Water tower,

depth in the model is 32 cm in.

depth in the actual will be 32x12=384 cm

15).

For wingspan,

Width in the model is 5.4 ft

Width in the actual will be 5.4x12=64.8 ft

16).

For Football helmet,

Diameter in the actual is 21cm

Diameter in the model will be 21/12=1.75 cm

The value of the fraction 3c+2/4 one less than the value of the fraction 5c-1/3.
Viefleur [7K]

Answer:

7/8 > 5/6

Step-by-step explanation:

A) 7/8

We can compare this as follows.

Lets say both are equal.

Cross multiplying these we get 40=42

We get 40<42. In fraction we get

In case if you want to convert this to decimal, we get;

5/6 = 0.833 and 7/8 = 0.875

We get 5/6<7/8

B) 4/5

Similarly we get 4/5 = 0.8 and 5/6 = 0.833

Here 4/5<5/6

C) 3/4

we get 3/4 = 0.75 and 5/6 = 0.833

3/4<5/6

D) 2/3

we get 2/3 = 0.66 and 5/6 = 0.833

2/3<5/6

Find the radius of convergence, r, of the series. ∞ xn 2n − 1 n = 1 r = 1 find the interval, i, of convergence of the series. (e
Bingel [31]
Assuming the series is

\displaystyle\sum_{n\ge1}\frac{x^n}{2n-1}

The series will converge if

\displaystyle\lim_{n\to\infty}\left|\frac{\frac{x^{n+1}}{2(n+1)-1}}{\frac{x^n}{2n-1}}\right|

We have

\displaystyle\lim_{n\to\infty}\left|\frac{\frac{x^{n+1}}{2(n+1)-1}}{\frac{x^n}{2n-1}}\right|=|x|\lim_{n\to\infty}\frac{\frac1{2n+1}}{\frac1{2n-1}}=|x|-\lim_{n\to\infty}\frac{2n-1}{2n+1}=|x|

So the series will certainly converge if -1, but we also need to check the endpoints of the interval.

If x=1, then the series is a scaled harmonic series, which we know diverges.

On the other hand, if x=-1, by the alternating series test we can show that the series converges, since

\left|\dfrac{(-1)^n}{2n-1}\right|=\dfrac1{2n-1}\to0

and is strictly decreasing.

So, the interval of convergence for the series is -1\le x.

Consider the parabola y = 5x − x2. (a) find the slope m of the tangent line to the parabola at the point (1, 4).
kkurt [141]
The tangent line to a curve is the one that coincides with the curve at a point and with the same derivative, that is, the same degree of variation.
 We have then:
 y = 5x-x²
 Deriving:
 y '= 5-2x
 In point (1, 4)
 The slope is:
 y (1) '= 5-2 * (1)
 y (1) '= 3
 The equation of the line will be:
 y-f (a) = f '(a) (x-a)
 We have then:
 y-4 = 3 (x-1)
 Rewriting:
 y = 3x-3 + 4
 y = 3x + 1
 Answer:
 the tangent line to the parabola at the point (1, 4) is
 y = 3x + 1
 the slope m is
 m = 3
