Answer:

D) Square

Step-by-step explanation:

We can start with the process of elimination.

Trapezoids don't have four right angles- can't be that. Neither do parallelograms.

So, we're just left with seeing whether rectangles have congruent sides- essentially, whether their sides are all the same shape or not.

Well, rectangles aren't always congruent. When you think of rectangle, usually, something with two long lines and two shorter lines comes to mind.

That leaves us with square.

The tires of a go-cart are 1 m in circumference. The tires revolve 15 times per second. What is the distance the go-cart travels

Likurg_2 [28]

Answer:

600 m

Step-by-step explanation:

The circumference of a tire is the distance around it. The distance around these tires is 1 m.

Since the tires revolve 15 times per second, this means every second the tires travel 15 m.

This means that in 40 seconds, the tires travel

15(40) = 600 m.

Instruction: use the ratio of a 30-60-90 triangle to solve for the variables. Leave your answers as radicals in simplest form.u=

almond37 [142]

Let's start by identify a 30-60-90 triangle

If we compare those two traingles we can stablish the following relation:

$\begin{gathered} a\sqrt[]{3}=6\sqrt[]{3} \\ \end{gathered}$

Therefore, a=6

u is the opposite side to the 90° angle, therefore

$\begin{gathered} u=2a \\ u=2\cdot6 \\ u=12 \end{gathered}$

on the other hand, v is the opposite side to the 30° angles, so

$\begin{gathered} v=a \\ v=6 \end{gathered}$

Which graph represents the function on the interval [-3,3] <br> F(x)=[x]-2

julia-pushkina [17]

<h2>Answer:</h2>

Shown below

<h2>Step-by-step explanation:</h2>

The most famous of the step functions is the greatest integer function, which is denoted by the parent function $[x]$ .

So, this function is defined as:

$f(x)=[x] \ the \ greatest \ integer \ less \ than \ or \ equal \ to \ x$ .

These are the characteristics of this function:

The domain of the function is the set of all real numbers.
The range of the function is the set of all integers.
The graph has a $y-intercept$ at $(0,0)$ and $x-intercept$ in the interval $[0,1)$
The graph is constant between each pair of consecutive integers.
The graph jumps vertically one unit at each integer value.

The function $F(x)=[x]-2$ represents the parent function shifted 2 units downward. Therefore, the correct option has been chosen in the attached figure.
