1) 2.65 - 0.63 =2 .02

2) 3.28 - 0.63 = 2.65

3)2.65 + -2.02 = 0.63

4) 0.63 - 3.28 = 2.65

Sorry for the long wait but hopefully this helps <3

Write each sum using summation notation.<br> 1+ 2 + 3 + 4 + ⋯ + 1000
AVprozaik [17]

Answer:

\sum_{k=1}^{1000} k

Step-by-step explanation:

You have to use the summation notation formula:

\sum_{k}^{n} f(k) = f(1) + f(2) +...+f(n)

where k is the starting number, n is the ending number and f(k) is the function or the expression to be added.

In this case, you have the sum of the integer numbers from 1 to 1000. Therefore, k=1 and n=1000.

Now, you have to obtain the function f(k) which is the representation of the expression needed to obtain the correct result of the sum.

f(k=1) = 1

f(k=2)=2

f(k=3)=3 ...

You can notice that the value of k corresponds to te value of f(k) therefore f(k) = k

Replacing the values of k, n and f(k) in the formula:

\sum_{k=1}^{1000} k = 1+2+3+4+...+1000

The triangular pyramid shown is made up of four congruent triangles. The length of the base is 8 inches, and the height of the b
Aneli [31]

Answer:

(B) Talia is correct. The lateral area can be found by approximating one large triangle, which can be found using the expression 4 (one-half (8) (6.9))

Step-by-step explanation:

Base of the Pyramid = 8 Inches

Height of the Triangular Face = 6.9 Inches

In any solid shape, the Lateral surface area is the sum of all sides except its top and bottom bases.

Since the four triangles are congruent:

Lateral Surface Area = 4 X Area of One Triangle

Area of a Triangle = \frac{1}{2}$ X Base X Height

Area of one Triangular Face = \dfrac{1}{2}(8)(6.9)

Therefore:

Lateral Surface Area = 4\left(\dfrac{1}{2}(8)(6.9)\right)

Therefore, Talia is correct.
