Answer:

They will be picked up at 2 \frac{1}{4} yards above sea level

Step-by-step explanation:

Let us consider sea level as reference and positions above sea level as positive and below sea level as negative.

With respect to this reference,

the position of top most point is +17 \frac{3}{4} yards

and the position of lower most point is -13 \frac{1}{4} yards

⇒ The position of midpoint is \frac{+17 \frac{3}{4} - 13 \frac{1}{4}}{2}

                                              = +2 \frac{1}{4}

∴ <u>They will be picked up at 2 \frac{1}{4} yards above sea level</u>

NEED SOME HELP HERE!!
Stolb23 [73]

Answer:

6 and 8

Step-by-step explanation:

Pythagorean theorem: a² + b² = c²

Given this,

(3x)² + (4x)² = 10²

9x² + 16x² = 100

25x² = 100

Divide both sides by 25

x² = 4

x = 2

Substitute this into 3x and 4x.

3x = 3 * 2 = 6

4x = 4 * 2 = 8

Thus, the answer is 6 and 8

A prisms characteristics are as followed

  First, a prism has two faces that are the same in shape and are parallel.  those two faces are sometimes called the <span>bases </span>of the prism.  Between these two faces are the rest of the sides of the prism which most of the time are rectangles. Prisms are normally named based on the shape of the two parallel faces.  For example, a prism with two parallel square faces would be known as a “square based prism” or sometimes just “square prism”.

What is the value of a in the polynomial
Alexandra [31]

Answer: a= 16

Step-by-step explanation:

We have the following expression:

(y-4)(y^2 +4y +16)

To find the value of the coefficient "a" you must use the distributive property to multiply the expression:

(y-4)(y^2 +4y +16)

until you transform it to the form:

y^3 +4y^2 +ay -4y^2 -ay-64

Then we have

(y-4)(y^2 +4y +16)\\\\(y^3 +4y^2 +16y -4y^2 -16y-64)\\\\

Therefore the value of a in the polynomial is 16
