A fence completely surrounds a pool,that is 30 feet by 10 feet.what is the approximate length,in feet,of the fence

tamaranim1 [39]

Because the fence's dimensions is 30 feet by 10 feet, you can assume that one side of the pool is 30 feet while the other, non-congruent side, is 10 feet. The formula for perimeter, which you are trying to find, is 2L+2W=P. In this problem, 30 will be your L and 10 will be your W. Therefore, 2(30) +2(10)=80.

So 80 feet will be your answer.

Estimate √125 to the nearest integer.

Damm [24]

Given:

The number is $\sqrt{125}$ .

To find:

The estimate value of given number.

Solution:

We have,

$\sqrt{125}=\sqrt{5\times 5\times 5}$

It can be written as

$\sqrt{125}=5\sqrt{5}$

We know that, $\sqrt{5}\approx 2.236$ . So,

$\sqrt{125}=5(2.236)$

$\sqrt{125}=11.18$

Approx the value to the nearest integer.

$\sqrt{125}\approx 11$

Therefore, the required integer is 11.

Which statement is true about the extreme value of the given quadratic equation? y = -3x2 + 12x − 33

Zina [86]

Answer:

The equation has a maximum value with a y-coordinate of -21.

Step-by-step explanation:

Given

$y =-3x^2 + 12x - 33$

Required

The true statement about the extreme value

First, write out the leading coefficient

$Leading = -3$

$-3 < 0$ means that the function would be a downward parabola;

Downward parabola always have their vertex on top of the parabola and as such, the function has a maximum value.

The maximum value is:

$x = -\frac{b}{2a}$

Where:

$a= -3; b =12; c =-33$

So, we have:

$x = -\frac{12}{2 * -3}$

$x = -\frac{12}{-6}$

$x =2$

Substitute $x =2$ in $y =-3x^2 + 12x - 33$

$y = -3*2^2 + 12 * 2 - 33$

$y = -21$

<em>Hence, the maximum is -21.</em>

Determine the intercepts of the line: -3x-4=-5y-8

Nina [5.8K]

The x-intercept is 4/3 and y-intercept is -4/5

Step-by-step explanation:

Given equation of line is:

$-3x-4=-5y-8$

To find the x-intercept, we put y=0 in the equation

$-3x-4=-5(0)-8\\-3x-4=0-8\\-3x-4=-8\\-3x=-8+4\\-3x=-4$

Dividing both sides by -3

$\frac{-3x}{3} = \frac{-4}{-3}\\x = \frac{4}{3}$

To find the y intercept, we put x=0

$-3(0)-4=-5y-8\\-4 = -5y-8\\-5y-8 = -4\\-5y = -4+8\\-5y = 4\\$

Dividing both sides by -5

$\frac{-5y}{-5} = \frac{4}{-5}\\y = -\frac{4}{5}$

Hence,

The x-intercept is 4/3 and y-intercept is -4/5
