6, the formula is (b1+b2/2)*h
8+12/2=10
10*h=60 so h=6

The arithmetic sequence a; is defined by the formula:

Morgarella [4.7K]

Answer:

The sum of the first 650 terms of the given arithmetic sequence is 2,322,775

Step-by-step explanation:

The first term here is 4

while the nth term would be ai = a(i-1) + 11

Kindly note that i and 1 are subscript of a

Mathematically, the sum of n terms of an arithmetic sequence can be calculated using the formula

Sn = n/2[2a + (n-1)d)

Here, our n is 650, a is 4, d is the difference between two successive terms which is 11.

Plugging these values, we have

Sn = (650/2) (2(4) + (650-1)11)

Sn = 325(8 + 7,139)

Sn = 325(7,147)

Sn = 2,322,775

Which of the following best describes interval C on the graph shown?

Slav-nsk [51]

Note: <em>The missing graph is attached below. </em>

Answer:

'linear decreasing' best describes interval C on the graph shown.

Step-by-step explanation:

Note: <em>The missing graph is attached below. </em>

From the attached graph, it is easy to figure out that the interval C on the graph shown is showing a straight line. So the graph of the function would be linear.

Also on the interval C, the value of y is decreasing as the value of x increase. So, the slope of the straight line would be negative.

So the interval C indicates that the function is decreasing there.

Therefore, 'linear decreasing' best describes interval C on the graph shown.

The function f(x)=1/4x+6 is vertically translated by 12 units in the negative direction. What is the y-intercept of the new func

s2008m [1.1K]

Since the function f(x) is written in the form y = mx + b, where m is the slope and b is the y-intercept, it currently has a y-intercept of b = 6. If this function is shifted downwards (vertically) by 12 units, its new y-intercept will be:
$6 - 12 = -6$

What is 7 + 8(2r - 9)

Shalnov [3]

7 + 8(2r - 9)

mutiply the bracket by 8

(8)(2r)= 16r

(8)(-9)= -72

7+16r-72

7-72+16r ( rearranging)

answer:

-65+16r or 16r-65
