State the domain and range of the relation { (-3,2),(4,1)(0.3),(5,2),(2,7)} .Then determine whether the relation is a function.

Novosadov [1.4K]

Answer:

Domain: {-3, 0, 2, 4, 5)
Range: {1, 2, 3, 7}

The relation is a function because for every x-value there is one y-value. In other words, for every input there is one output.

The eqution of the diagonal of a parallelogram is 3y=5x +k. The two opposite vertices of a parallelogram are the points (1,-2),

astraxan [27]

Answer:

$k = 1$

Step-by-step explanation:

Given

$3y = 5x + k$

Opposite points: $(1,-2)$ and $(-2,1)$

Required

Find k

First, calculate the midpoint of the opposite points.

$(x,y) = 0.5(x_1 + x_2,y_1 + y_2)$

This gives:

$(x,y) = 0.5(1 -2,-2 + 1)$

$(x,y) = 0.5(-1,-1)$

Open bracket

$(x,y) = (-0.5,-0.5)$

The equation $3y = 5x + k$ becomes:

$3 * -0.5 = 5 * -0.5 + k$

$-1.5 = -2.5 + k$

Solve for k

$k = 2.5-1.5$

$k = 1$

How many times smaller is 2 × 10-3 than 4 × 10-2? PLEASE HELP

NNADVOKAT [17]

<h2>The required "option A) 20" is correct.</h2>

Step-by-step explanation:

Let x be the smaller than 4 × $10^{-2}$ .

To find, the number of times smaller is 2 × $10^{-3}$ than 4 × $10^{-2}$ = ?

∴ x = $\dfrac{4\times 10^{-2}}{2\times 10^{-3}}$

= 2 × $10^{-2}$ × $10^{3}$

Using the identity,

$a^{m}=\dfrac{1}{a^{-m}}$

= 2 × $10^{-2+3}$

Using the identity,

$a^{m} \timesa^{n}=a^{m+n}$

= 2 × $10^{1}$

= 2 × 10

= 20

Thus, the required "option A) 20" is correct.
