F(x)=4x2-3x+5 f(2) find function value

Mathematics

Hello!

This question is an example of function notation. Function notation is basically f(x) , said as "f of x". To solve this problem, you need to substitute x = 2 into each x-value in this equation. F(2) is written as function notation, while x = 2 is not.

F(2) = 4x² - 3x + 5

F(2) = 4(2)² - 3(2) + 5

F(2) = 4(4) - 6 + 5

F(2) = 16 - 6 + 5

F(2) = 15

Therefore, the value of F(2) is 15.

1 2/5m - 3/5 ( 2/5m + 1 )
Hunter-Best [27]

Answer:

1 4/25 - 3/5, or 29/25 - 3/5, or \frac{(29m - 15)}{25}

it doesn't really matter they all mean the same

Step-by-step explanation:

1 2/5m - 3/5(2/5m + 1)

multiply first

1 2/5m - 6/25m - 3/5

multiply 1 2/5 only so the denominator is 25 as we can't simplify 6/25, it's so we can add them together, we can't add 3/5 tho bc it's a different term so there's no need to multiply that.

1 10/25m - 6/25m - 3/5

add/subtract

1 4/25m - 3/5

Mjhs is refinishing a basketball court and decided to paint everything shown below blue. How many square feet will be painted bl
SashulF [63]

Answer:

<h2>Mjhs needs 189.25 square feet of blue paint, approximately.</h2>

Step-by-step explanation:

As you can observe in the image attached, the basketball court is a composite figure formed by a rectangle and half of a circle.

The rectangle has dimensions of 10 feet by 15 feet. The circle has a diameter of 10 feet.

The expression of this composite area would be

A= w \times l + \frac{\pi (\frac{l}{2} )^{2} }{2}

Where w = 15 \ ft and l = 10 \ ft. Replacing these values, we have

A= 15 \times 10 + \frac{3.14 (\frac{10}{2} )^{2} }{2}\\ A=150 + \frac{3.14 \times 25}{2}=150+39.25 \\ A \approx 189.25 \ ft^{2}

Therefore, Mjhs needs 189.25 square feet of blue paint, approximately.
