Answer 2

The roots of the given quadratic equation are x=-1.6 and x=-6.4.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

here, we have,

given that,

The given equation is x² - 8x + 41 =0.

The given equation can be solved using quadratic equation formula.

Here, by comparing x² - 8x + 41 =0 with ax²+bx+c=0, we get a=1, b=-8 and c=41.

Quadratic equation formula x = -b±√b² - 4ac / 2a

Now, x= -8 ± √ 64 - 41 / 2×1

⇒ x= -8 ± √23 / 2

⇒ x= -8 ± 4.8 /2

⇒ x=-1.6 or x=-6.4

Therefore, the roots of the given quadratic equation are x=-1.6 and x=-6.4.

How many 3/4ths are in 1

Answers

Answer:

4/3

Step-by-step explanation:

1÷3/4 = 1*4/3 = 4/3

GIVE BRAINLIEST

Answer:y=4/3 as an improper fraction or 1 1/3 as a mixed number (decimal: 1.3333…). There are 1 1/3rd 3/4s in 1.

PREMISES

y=1/(3/4)

CALCULATIONS

The number of 3/4s in 1 can be denoted naively as:

y=1/(3/4)

y=1(4/3) (Flip the primary divisor and multiply since multiplication is the inverse of division)

y=

4/3 as an improper fraction or 1 1/3 as a mixed number (decimal: 1.3333…)

PROOF

If y=4/3, then the equations

(1 1/3)(3/4)=1

4/3(3/4)=1 and

1=1 prove the solution “how many 3/4s are in 1?

n=3n+162, minus, start fraction, 1, divided by, 2, end fraction, n, equals, 3, n, plus, 16
�

n=n, equals

Answers

To solve this equation, we can first simplify the left-hand side:

2^(3n+1) / (2^n - 1) = 3n + 16

We can then multiply both sides by 2^n - 1 to eliminate the denominator:

2^(3n+1) = (3n + 16)(2^n - 1)

Expanding the right-hand side:

2^(3n+1) = 6n*2^n + 16*2^n - 3n - 16

Simplifying:

2^(3n+1) = (6n - 3n)*2^n + (16 - 16)

2^(3n+1) = 3n*2^n

Dividing both sides by 2^n:

2^(n+1) = 3n

Taking the logarithm of both sides (with any base), we get:

n log(2) + log(2) = log(3n)

n = (log(3n) - log(2)) / log(2)

We can use a calculator to evaluate this expression, or simplify it further using logarithm rules:

n = log2(3n/2)

We can now use iterative methods or a graphing calculator to find a numerical solution for n. The solution is approximately 7.524.

The solution would be 7.524 I’m pretty sure

A. 4 grades per minute
B. 15 grades per minute
C. 16 grades per minute
D. 960 grades per minute

Answers

Answer:

C. 15 grades per minute.

Step-by-step explanation:

Divide 120 by 8

120÷8=15

It's 15 because multiplying it by 8 instead of dividing it gives you 120.

C. 15 grades per minute

If you do 15x8 you get 120 so if you reverse it and use division 8 divided by 120 you get 15

Evaulate each expression when n = 2.3

N + 8n2 - 17=

Answers

Answer: 27.62

Step-by-step explanation:

plug in 2.3 wherever 'n' is

I'm assuming that the '2' in 8n2 is an exponent

2.3 + 8(2.3)² - 17 =

Using PEMDAS

start out with exponent since there isn't any parenthesis  

(2.3)² = 5.29

2.3 + 8(5.29) - 17

move on to multiplication

8(5.29) = 42.32

2.3 + 42.32 - 17

with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there

2.3 + 42.32 = 44.62

then the subtraction

44.62 - 17 = 27.62

Evaluate (whith steps) -3 - 5 (8 + 4) + 16 - 32

Answers

Answer:

Using the order of operations (PEMDAS), we evaluate the expression as follows:

First, we perform the operations inside the parentheses: 8 + 4 = 12.

Next, we multiply 5 by 12: 5(12) = 60.

Then, we combine the like terms: -3 - 60 + 16 - 32 = -79.

Therefore, -3 - 5 (8 + 4) + 16 - 32 = -79.

The answer is -79 ( I think )
