Answer:x=9
Step-by-step explanation:
6x+25=79
-25 -25
6x=54
/6 /6
x=9
<span>This exercise should show you that as h approaches zero
you get the value of the derivative of x^2 at x=1.
</span><span>the change in x^2) / h
h=1___
h=.1____
h=0.1_____
h=.001___
</span>
<span>change in x^2 = (1+h)^2 - 1^2 = (1+h)^2 - 1</span>
In order to solve for a nth term in an arithmetic sequence, we use the formula written as:
an = a1 + (n-1)d
where an is the nth term, a1 is the first value in the sequence, n is the term position and d is the common difference.
First, we need to calculate for d from the given values above.
<span>a1 = 38 and a17 = -74
</span>
an = a1 + (n-1)d
-74 = 38 + (17-1)d
d = -7
The 27th term is calculated as follows:
a27 = a1 + (n-1)d
a27= 38 + (27-1)(-7)
a27 = -144 -----------> OPTION D
27000 x .3 = 8100
8100 x 3 = 24300
27000 - 24300 = 2700
If it’s a regular quadrilateral and c is a right angle then c will be 90 degrees
