Answer:  69m^2

Step-by-step explanation:

we can find the area of shaded region by  subtracting the area of removed region.

so,

area of rectangle= length*width

for area of removed region

=4m*2m=8m^2

for area of  larger region

=11m*7m=77m^2

Now final destinaltion

area of shaded region=area of lareger region-area of smaller region

                                     =77m^2-8m^2

                                    =69m^2

Arthur drops a ball from a height of 81 feet above the ground. Its height, h, is given by the equation h = –16t2 + 81, where t i
Lorico [155]

Answer:

Step-by-step explanation:

We are given the position function and need to find the value of t when h<17.

Create an inequality that represents this situation:

-16t^2+81 The "less than" sign makes this very specifically a conjunction problem as opposed to a disjunction. That's important to the solution. But we'll get there.

The simplest way to solve this is to subtract 81 from both sides:

-16t^2 then divide both sides by -16:

t^2>4 Notice now that the sign is facing the other way since we had to divide by a negative number. Now it's a disjunction. The solution set to this inequality is that t>2 or t<-2. First and foremost, time will never be negative, so we can disregard the -2. Even if that was t<2, the more time that goes by, the greater the time interval is, not the lesser. It's the "<" that doesn't make sense, not only the -2. The solution to this inequality is

t > 2 sec. That means that after 2 seconds, the height of the ball is less than 17 feet.

The product of 2 and the second power of y in algebraic expression
inysia [295]
<span>Algebraic expression of product of 2 and the second power of y
=> Algebraic expression is a combination of integers (numbers), variables (a, b, c, x, y, ….), exponent (2 5 3 …) that is a rational number and algebraic operations like subtraction (-), addition (+), multiplication (x) and division (/).
=> Product – result of multiplication
=> second power of y = y<span>2
</span>=> 2 x y<span>2

</span>Thus, the algebraic expression of product of 2 and the second power of y is equals to 2 x y2

Find the equation of the line that is perpendicular to y = -3/4 + 1 and contains the point 9,12. The answer must be a whole numb
Leviafan [203]

Answer:

The perpendicular equation is y = 4/3x

Step-by-step explanation:

To find the equation perpendicular to this, we first need to look at the slope of the original line, which is -3/4. Perpendicular lines have opposite and reciprocal slopes, meaning that the new line would have 4/3 slope. Now we can use this and the point in point-slope form to get the final equation.

y - y1 = m(x - x1)

y - 12 = 4/3(x - 9)

y - 12 = 4/3x - 12

y = 4/3x
