Answer: Moses pays $2.50, and Marvin pays $1.50.

Step-by-step explanation: To solve this question, you have to find the unit rate.

8 pens for $4

4/8= 0.5/1

So, one pen is equal to 50¢.

Then, you just have to multiply how many pens each one buys by the price of one pen.

0.5*5=2.5

0.5*3=1.5

When you add them together, you come up with the amount the question have in the beginning.

2.5+1.5= 4

To conclude, Moses pays $2.50, and Marvin pays $1.50.

How to find minimum and maximum of this equation.

Westkost [7]

Using it's vertex, the maximum value of the quadratic function is -3.19.

<h3>What is the vertex of a quadratic equation?</h3>

A quadratic equation is modeled by:

$y = ax^2 + bx + c$

The vertex is given by:

$(x_v, y_v)$

In which:

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

$y_v = -\frac{b^2 - 4ac}{4a}$

Considering the coefficient a, we have that:

If a < 0, the vertex is a maximum point.

If a > 0, the vertex is a minimum point.

In this problem, the equation is:

y + 4 = -x² + 1.8x

In standard format:

y = -x² + 1.8x - 4.

The coefficients are a = -1 < 0, b = 1.8, c = -4, hence the maximum value is:

$y_v = -\frac{1.8^2 - 4(-1)(-4)}{4(-1)} = -3.19$

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.
