Evaluate. f(x) = 2x - 1, f(2)

Answers

Answer 1
Answer:

Answer:

f(2) = 3

Step-by-step explanation:

Substitute 2 for x, and evaluate the expression.

f(x) = 2x - 1

f(2) = 2(2) - 1

f(2) = 4 - 1

f(2) = 3
Answer 2
Answer: answer: so, f(x)=2(2)-1
which will be =3 so answer is 3

the model an=395n +5419 describes the cost of tution and fees at public colleges in academic year n, where n=1 corresponds to the school year ending in 2007,n=2 to the school year ending in 2008 and so on four years

use this and the formula for sn to find the total cost of tution and fees at public colleges for four years

Answers

Just substitute 4 in for n, then you would get 395*4 +5419. That is 6999, so it's 6999 for four years.
\boxed{a_n=395n+5419}\n \n a_4=395*4+5419\n \n a_4=1580+5419\n \n \boxed{\boxed{a_4=6,999}}

Estimate the answer by rounding 863 x 534 to the nearest 100

Answers

Answer:

Step-by-step explanation:

If I rounded to the nearest hundred it would look like this 900 and 500.

because the closest hundred type number is 900 and the same for the number 500

Answer:

450,000

Step-by-step explanation:

To estimate the answer by rounding 863 x 534 to the nearest 100, follow these steps:

1. Multiply the tens digit of both numbers: 8 x 5 = 40

2. Round each number to the nearest 100: 863 ≈ 900 and 534 ≈ 500

3. Multiply the rounded numbers: 900 x 500 = 450,000

4. The estimated answer to the nearest 100 is 450,000.

Therefore, when rounding 863 x 534 to the nearest 100, the estimated answer is 450,000.

The orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula P = a Superscript three-halves. If Saturn’s orbital period is 29.5 years, what is its distance from the sun?

Answers

Answer:

9.54731702 astronomical units

Step-by-step explanation:

P=a^{(3)/(2) }

Substitute this value in the equation above:

29.5=a^{(3)/(2) }

⇒ (29.5)^{(3)/(2) } =a

⇒ a=9.54731702astronomicalunits

Hence, its distance from the sun is 9.54731702 astronomical units.

Answer:

The third side of an isosceles triangle is known as the base. To find the length of the base, we can use the Pythagorean theorem. If we call the base of the triangle "b", then the length of the base is the square root of (8^2 - 5^2), which is equal to sqrt(64 - 25) = sqrt(39) = 6.3 cm.

4x - 7 < 5 which is not a solution to the inequality

Answers

First, you want to subtract 7 from both sides. On the left, it cancels out, so you're just left with 4x. On the right, your left with -2. Then, you divide 4 on both sides. On the left, it cancels out, and on the right it leaves you with 0.5. Anything below 0.5 (for ex 0, 0.25) would be correct. Anything above will be incorrect. Hope this helped!
