Answer:

A. 7*5 + 4^2 - 2^3 / 4 = 35 + 16 - 8 / 4 = 35 + 16 - 2 = 49

B. The statement of seven times five plus four squared minus 2 cubed divided by 4 is equal to 49. (or whatever your friend's teacher wants when they ask for a complete sentence).

C. PEMDAS - parentheses, exponents, multiplication, division, addition, subtraction

Note:

When remembering PEMDAS, please remember that multiplication actually isn't prioritized over division - they should be performed "simultaneously" from left to right. Same with addition and subtraction. The order is: P -> E -> MD -> AS.

The surface area of an oil spill gets 105% larger every day, represented by the function s(x) = (1.05)x − 1. On the first day, i
ioda
The given scenario above is like a geometric sequence with r or common ratio being 1.05 and the first term being 31 square meters. The nth term of the sequence is calculated through the equation,
                        A15 = (A1)(r)^(n - 1)
Substituting,
                        A15 = (31)(1.05)^(15 - 1) = 61.3778 square meter
Therefore, the area covered by the spill after the 15th day is approximately 61.4 square meters.

kkurt [141]

Answer:

Option D is correct.

a_3 = \frac{-1}{2}

Step-by-step explanation:

The sequence is in the form of :

a_1, a_2, a_3, a_4, .......

where

a_1 represents the First term.

a_2 represents the Second term.

a_3 represents the Third term.

a_4 represents the Fourth term and so on.....

we have to calculate the a_3 in the given sequence:

Given the sequence:  -4 , -2, -\frac{1}{2} , -\frac{1}{4}, ......    

a_3 = \frac{-1}{2}

Therefore, the third term a_3 = \frac{-1}{2}
