HELP!! For a right square pyramid, which shape could not be a cross section?
Artyom0805 [142]

Answer:

D. Rectangle

Step-by-step explanation:

If you cut the pyramid with a plane parallel to the base, a square is obtained. If the plane is perpendicular to the base, you can obtain two different figures; if the plane passes through the vertex, a triangle is obtained, but if it doesn't pass through the vertex, a trapezoid is obtained.

Which table represents a function?
zalisa [80]

Answer:

3

Step-by-step explanation:

to be a function, there has to be exactly one x for every y. if there is more than one per y, it makes it not a function. so, if there is two of the same number in the x, it's not a function.

The solution of the equations is (-2, -1)

<h3>System of equation:</h3>

2x - 3y = -1

11x  - 9y = -13

Using elimination method let multiply the first equation by -3.

Therefore,

-6x + 9y = 3

11x - 9y = -13

5x = -10

x = -10 / 5

x = -2

let's find y as follows;

2(-2) - 3y = -1

-4 - 3y = -1

-3y = -1 + 4

-3y = 3

y = 3 / -3

y = -1

Write the quadratic function in vertex form.
melisa1 [442]
Complete the square
isolate x terms
y=(x^2-14x)+53
take 1/2 of -14 and square it ((-7)^2=49
add plus and minus of that inside the parntehasees

y=(x^2-14x+49-49)+53
factor perfect suqrae
y=((x-7)^2-49)+53
get rid of parnthasees
y=(x-7)^2-49+53
y=(x-7)^2+4

Stacy wants to build a patio with a small, circular pond in her backyard.The pond will have a 6-foot radius. She also wants to i
solong [7]
First we are going to find the Area of the pond using the area of a circle formula: A= \pi r^2
where
A is the area of the circle 
r is the radius of the circle 
We know for our problem that the pond will have a 6-foot radius, so r=6. Lets replace that value on our area formula:
A= \pi r^2
A= \pi (6)^2
A=113.1ft^{2}
We know that the <span>cost of installing the pond is $0.62 per square foot, so lets multiply the area we just found by the cost:
Total cost of pund=</span>(0.62)(113.1)=70.12 dollars

Now, let x be the width the rectangle, so its length will be x+13. Remember that the area of a rectangle is width times length, so:
A=x(x+13)
A=(x^2+13x)ft^2
Since the cost of installing ties is $1, the cost of installing ties in our rectangle will be x^2+13x dollars.

<span>Stacy can spend no more than $536 on this project, so we can setup an inequality relating the cost of the pound and the cost of installing ties:
</span>70.12+x^2+13x \leq 536
x^2+13x \leq 465.88

We can conclude that the inequality that can be used to fin the width, x, of the patio is x^2+13x \leq 465.88
