Answer:

7.96 *10^8kg

Step-by-step explanation:

Given

Eiffel = 9.16 * 10^6\ kg

Golden\ Gate =8.05 * 10^8kg

Required

Determine the difference in mass

This is calculated by subtracting the mass of Eiffel tower from the mass of Golden gate bridge

Difference = Golden\ Gate - Eiffel

Difference = 8.05 * 10^8 - 9.16 * 10^6

Express 10^8 as 10^6 * 10^2

Difference = 8.05 * 10^2*10^6 - 9.16 * 10^6

Express 10^2 as 100

Difference = 8.05 * 100*10^6 - 9.16 * 10^6

Difference = 805 *10^6 - 9.16 * 10^6

Factorize:

Difference = (805- 9.16) * 10^6

Difference = 795.84 * 10^6

Factorize the decimal number

Difference = 7.9584 *10^2 * 10^6

Difference = 7.9584 *10^8

Approximate:

Difference = 7.96 *10^8

Show that tangent is an odd function.Use the figure in your proof.
svlad2 [7]

We have to prove that the tangent is an odd function.

If the tangent is an odd function, the following condition should be satisfied:

\tan(t)=-\tan(-t)

From the figure we can see that the tangent can be expressed as:

We can start then from tan(t) and will try to arrive to -tan(-t):

\begin{gathered} \tan(t)=\frac{\sin(t)}{cos(t)}=\frac{y}{x} \\ \tan(t)=\frac{-(-y)}{x}=\frac{-\sin(-t)}{\cos(-t)} \\ \tan(t)=-\frac{\sin(-t)}{\cos(-t)} \\ \tan(t)=-\tan(-t) \end{gathered}

We have arrived to the condition for odd functions, so we have just proved that the tangent function is an odd function.

Which place is the 7 in? 502.78 tens tenths ones hundredths
Marina CMI [18]

Answer:

tenths

Step-by-step explanation:

Suppose a number is given in the form ABC.ZYX

The place values would be:

C is ones

B is tens

A is hundreds

Z is tenths

Y is hundredths

X is thousandths

Looking at the number 502.78, we see that "7" is the first right place after decimal, which is same as "Z", which is tenths.

Hence 7's place value is tenths

a rectangle box has length 12 inches, width 15 inches, and a height of 17 inches. Find the angle between the diagonal of the box
ANTONII [103]

Answer:

0.7246 radians

Step-by-step explanation:

According to the Question,

Given that, a rectangle box has length 12 inches, width 15 inches, and a height of 17 inches

  • The length of the base diagonal (d) can be found using the Pythagorean theorem on length and width:

d = √{ (12)² +(15)² }  = √(144+225) = √369inches

  • The tangent of the angle is the ratio of the height of the box to this length

 Tan∅ = 17/√369

Taking the Tan^{-1} , we have

∅ = Tan^{-1}(17/√369) ≈ 0.7246 radians
