No. A solution is any co ordinated that lies in the blank space on the graph. (-2,-3) is in the blue shades section so it is not a solution.

The length of a box as reported by its manufacturer is 13.67 cm. Joe has a ruler which has markings for each millimeter. Which m

AlekseyPX

Answer:

Option (3)

Step-by-step explanation:

Joe has a ruler which has markings for each millimeter, so the least measurement which Joe can do is in millimeter.

Since, 10 mm = 1 cm

Therefore, 1 mm = 0.1 cm

This rule states that Joe can measure a length or distance in nearest tenth of a cm only.

If length of a box = 13.67 cm,

So Joe can measure it as 13.7 cm approximately.

Therefore, Option (3) will be the answer.

Yet another question.

inna [77]

Answer:

t= 3 years

Step-by-step explanation:

So far we have 2 useful relationships $P_{t}= P_{o} e^{r*t}$ and $P_{t}=2P_{0}$

Now, clearing t

$P_{t}= P_{o} e^{r*t} \\\frac{ P_{t}}{P_{o}} = e^{r*t}\\\frac{2 P_{0}}{P_{o}} = e^{r*t}\\2 = e^{r*t}$

I apply logarithm

$log(2)=r*t\\ t=\frac{log(2)}{r}\\t=\frac{0.3}{0.1} \\ t=3$ years

Select from the matches below to correctly complete the statements. I'll give brainliest to someone with correct answer!

Aneli [31]

Answer:

<h3>The correct matches as follows :</h3>

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

3) The product of a linear monomial and a linear binomial - Quadratic binomial

Step-by-step explanation:

The correct matches as follows :

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

<h3> Monomial is a linear expression having only term with degree 1 (variable)</h3>

For Example : Let x and y be two monomials which is linear
If we product the two linear monomials we get
$x\times x=x^2$ which is a quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

<h3>For example : Let $x^2$ be the Quadratic monomial has one term with degree 2 and $x^2+2x+3$ be the quadratic trinomial ( has 3 terms with degree) </h3>

If we product the quadratic monomial and quadratic trinomial we have
$x^2\times (x^2+2x+3)=x^2(x^2)+x^2(2x)+x^2(3)$

$=x^4+2x^3+3x^2$
Therefore $x^2(x^2+2x+3)=x^4+2x^3+3x^2$ which is a quartic trinomial has degree 4 with three terms

3) The product of a linear monomial and a linear binomial - Quadratic binomial

<h3>For example : Let x be the linear monomial and $x^2+5$ be the linear binomial has two terms with degree 1</h3>

If we product the linear monomial and quadratic binomial we get
$x\times (x+5)=x(x)+x(5)$
$=x^2+5x$

Therefore $x\times (x+5)=x^2+5x$ which is a quadratic binomial with degree 2
