250

B.
125

C.
80

D.
40

Answers

Answer 1

Answer: It would be C.80 because if you divide 10,000 by 250 then multiply the answer which is 40 by 2 the answer would be 80

Rule: add 15, subtract 10 first term 4

Answers

The order for the given rule is 4, 19, and 9 if the rule is to add 15 and deduct 10 from the first term.

What is a sequence?

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.

It is given that, the rule of the sequence is to add 15, subtract 10 first term 4,

We have to apply the arithmeticoperation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

If the first term is 4 add 15 first and subtract 10 from it,

=4 + 15

=19

=19-10

Thus, the order for the given rule is 4, 19, and 9 if the rule is to add 15 and deduct 10 from the first term.

[(-8)-{(-14)/(-7)}^3]x(-3)+(-3)-34

Answers

Answer:

Step-by-step explanation:

The given expression is as following:

$((-8) - ((-14)/(-7) )^3)*(-3)+(-3)-34$

According to PEMDAS

calculate the process at the Parentheses first then the exponent.

So,

= $((-8) - (2 )^3)*(-3)+(-3)-34\n= ((-8) - 8)*(-3)+(-3)-34\n=(-16)*(-3)+(-3)-34\n=48+(-3)-34\n=48-3-34\n=11$

BEST GETS BRAINLIESTThe water height of a pool is determined by
8g^2 + 3g − 4, the rate that the pool is filled, and 9g^2 − 2g − 5, the rate that water leaves the pool, where g represents the number of gallons entering
or leaving the pool per minute.
a. Write an expression that determines the height of the water in the pool.
b. What will be the height of the water if g = 1, 2, 3, and 4?
c. To the nearest tenth, at which value for g will the water reach its
greatest height? Explain.

Answers

a) Water height, H(g) = 8g^2 + 3g -4 - [9g^2 -2g -5] = 8g^2 + 3g -4 -9g^2 + 2g +5 = -g^2 +5g +1

b) g = 1
H(g) = -(1)^2 + 5(1) + 1 = -1 + 5 + 1 = 5

g=2
H(g) = -(2)^2 + 5(2) + 1 = -4 + 10 + 1 = 7

g=3
H(g) = -(3)^2 + 5(3) + 1 = -9 +15 +1 = 5

c) Greatest height

Find the vertex of the parabole

The vertex is at the mid point between the two roots.

To find the roots you can use the quadratic equation

The result is g = 5/2 + [√29]/2 and g = 5/2 - [√29]/2

The middle poin is 5/2 = 2.5

Now find H(2.5) = -(2.5)^2 + 5(2.5) + 1 = 7.5 ≈ 7.3

Is 9/16 less than or greater than 5/8
