What Is The Value Of The Expression Below When Y=54y2-7y-6

Answers

Answer 1

Answer and Step-by-step explanation:

Let's plug 5 in for y.

[tex]4(5)^{2} - 7(5) - 6\\\\\\\\4(25) - 35 - 6\\\\\\100 - 35 - 6 = 59\\\\\\[/tex]

The value of [tex]4y^{2} - 7y - 6[/tex] when y is equal to 5 is 59.

Answer 2

Answer:

59

Step-by-step explanation:

You can just replace y with its value which is 5.

4y² - 7y - 6 = 4(5²) - 7(5) - 6

                  = 4 × 25 - 35 - 6

                  = 100 - 35 - 6

                  = 59

Find the probability that a randomly selected points within a square falls in the blue shaded area (circle)

Answers

Answer:

78.8 %

Step-by-step explanation:

From the question,

Area of the square = L²

A = L²

Where L = Length of the square.

From the diagram,

L = 4 in

Therefore,

A = 4²

A = 16 in².

Also,

Area of the circle (A') = πr²

Where r = radius of the circle.

Given: r = 2 in

Therefore,

A' = 22/7(2²)

A = 12.6 in²

Hence,

The probability that a randomly selected points within a square falls in the blue shaded area (Pr) = A'/A

Pr = 12.6/16

Pr = 0.7875

Pr(%) = 78.75

Pr(%) = 78.8 %

p-5 = 19
answer step by step & explain

Answers

Answer:

Step-by-step explanation:

Very simple.

p - 5 = 19

So to take out the -5 on that side, you must also do the same thing to the other side. So adding 5 in one side of the equal sign would mean you have to do the same thing on the other side of the equal sign.

SO:

p-5 +5 = 19+5

p = 24

P=26

26-5=19


(19+5 is also 26 so you can check your work that way)
