Answer:
=6590000000 or 6.59 x 10^9 (^ raises the number as an exponent)
Step-by-step explanation:
=(6.648 x 10 to the power of 9) - (2.9 x 10 to the power of 7)
or we could just expand the numbers
like,
= 6619000000- 29000000
and then calculate to get the answer which equals 6590000000 or 6.59 x 10^9 when written in a scientific form
Here, a = 3/4, d = 1 - 3/4 = 1/4, n = 13
a(n) = a + ( n - 1)d
a(n) = 3/4 + (13-1)1/4
a(n) = 3/4 + 12/4
a(n) = 3/4 + 3
a(n) = 15/4
a(n) = 3 3/4
In short, Your Answer would be Option D

Using the slope concept, it is found that the angle of elevation to the top of the bridges is of 57.7º.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>.
It's also the tangent of the angle of depression.
In this problem:
- The horizontal change is of 60 m.
- The vertical change is of 100 - 5 = 95 m.
Hence:
The angle of elevation to the top of the bridges is of 57.7º.

Answer:
Step-by-step explanation:
x =(-7+√-7)/-2=(7-i√ 7 )/2= 3.5000+1.3229i
or:
x =(-7-√-7)/-2=(7+i√ 7 )/2= 3.5000-1.3229i
3h-12
h=4
4 times 3 =12
4(10-h)
4(10-4)
10-4=6
