Answer:

$6518.75

Step-by-step explanation:

In order to calculate the are of the parking lot without the area of the arena we just have to withdraw form the area of the parking lot hald of the area of the arena, to calculate the area of the perking lot, it would be:

A=BxH

A=100x75

A=7500

Now the area of the arena:

A=\pi r^{2}

A=\pi 25^{2}

A=\pi 25^{2}

A=1962,5

As you can see in the image, the area is cut by half by a side of the car park, so we only have to withdraw half of the arena from the area of the parking lot.

Area in the car park without the area:

A=Area-half-arena\\A=7500-981.25\\A=6518.75

So the area of the parking lot without the arena is 6518.75

Evaluate |x| + (-2x 2) for x = 3.
Amiraneli [1.4K]
<h2>Hello!</h2>

The answer is:

f(3)=|x|+(-2x^{2})=-15

<h2>Why?</h2>

Evaluating a function means replacing the variable with the given value (3 for this case).

To evaluate the function, we need to remember that the absolute value guarantees a possitive value, for example:

|-3|=3\\|-4|=4

So, we are given the function:

f(x)=|x|+(-2x^{2})

Then, evaluating we have:

f(3)=|3|+(-2*(3)^{2})=3+(-2*9)=3-18=-15

Hence, the answer is:

f(3)=|x|+(-2x^{2})=-15

Have a nice day!

A trapezoidal sum is an underestimate when the function is.
Elis [28]

Answer: Concave down

Explanation:

An example is shown below. We have the concave down parabola y = -x^2+7 marked in red. The trapezoidal sum is in blue. The three trapezoids combine to something just a bit smaller than the true area under the curve from x = -2 to x = 1. Therefore, this trapezoidal sum is an underestimate of the true area under the curve.

Every part of each trapezoid is completely below the red curve. In other words, no part of the blue pieces spill above the parabola.

-3/10+-1/5
Nataliya [291]

Step-by-step explanation:

-3/10+ -1/5

find the common denominator. on that case its 10

10 into 10 that's 1 so 3 remain 3 . then 5 into 10 its 2 so 1×2=2

-3/10 + -2/10

-3+-2

-3-2= -5

-5/10= -1/2

Ans is -1/2

-18/15 ×5/-4

you cross multiply. 5into 15 to get a denominator 3 then -4/2=-2 denominator. -18/2=-9. you multiply 3×-2=-6 then we are left with

-9/-6= -3/-2=1 and half

Ans is 1 1/2 (one and 1 half ).

3/8÷ -1/4

you spin -1/4 to -4/1 inorder to change the sign to a multiplication sign.

3/8 × -4/1 1

cross multiply to get -3/2

-3/2 = - 1 1/2

Ans : 1 1/2 ( one and one half )
