Use Gauss's approach to find the following sums (do not use formulas). 1+3+5+7+...+1001

kramer

Hello,

$s=1+2+3+...+1000+1001=\sum_{i=1}^{1001}\ i \ (1) \\ 

s=1001+1000+...+3+2+1=\sum_{j=1}^{1001}\ 1002-j \ (2)\\

(1)+(2)==\textgreater \ 2*s=(1+1001)+(2+1000)+...+(1000+2)+(1001+1)\\

=1002*1001=(\sum_{i=1}^{1001}\ i )\ +(\sum_{i=1}^{1001}\ 1002-i )\ \\

=\sum_{i=1}^{1001}\ ( i+1002-i)\ = \sum_{i=1}^{1001}\ 1002=1001*1002\\

So\ s= \dfrac{1001*1002}{2} =501501\\

Using ƒ(x) = 2x + 7 and g(x) = x − 3, find ƒ(g(-2)).

Eva8 [605]

Answer:

We conclude that:

f(g(-2)) = -3

Step-by-step explanation:

Given

f(x) = 2x + 7

g(x) = x-3

To determine

f(g(-2)) = ?

In order to determine f(g(-2)), first we need to determine g(-2)

so substituting x = -2 in g(x) = x-3

g(-2) = -2 - 3

= -5

Thus,

f(g(-2)) = f(-5)

now substitute x = -5 in the function f(x) = 2x+7

f(x) = 2x+7

f(-5) = 2(-5) + 7

f(-5) = -10 + 7

f(-5) = -3

f(g(-2)) = f(-5) = -3

Therefore, we conclude that:

f(g(-2)) = -3

BRAINLIEST ASAP! PLEASE HELP ME :)

Answer:

m <1 = 61

Step-by-step explanation:

We know that the angle adjacent to 130 is 50 degrees because linear angles are complementary.

Extending line t to make a triangle, we can find the angle adjacent to the angle labeled 111 ( and above it) is 69.

That makes the angle that touches line q 61 to finish the triangle

This angle and angle 1 are corresponding angles, so they are equal

<1 = 61
