Answer:

4m

Step-by-step explanation:

It would be 4m as there are four different copies and the variable being used originally is 'm'. Therefore, we can move it around and since multilication is d addtiion, we would correct this to 4m.

Need help with this.

Mars2501 [29]

Step-by-step explanation:

put some x values into the equation

i.e : -2, -1, 0 ,1 ,2

3/5 (-2) +2 = 4/5 (-2, 4/5)

3/5 (-1) +2 = 7/5 (-1, 7/5)

3/5 (0) +2 = 2 (0, 2)

3/5 (1) +2 = 2.6 (1, 2.6)

3/5 (2) +2= 3.2 (2, 3.2)

Then plot these on the graph as corodinates with the x values

Write 162 as a product of primes.<br> Use index notation when giving your answer.

Anika [276]

Answer:

2²×3³

Step-by-step explanation:

162 can we shown as:

81*2=162 as 2 is prime we leave it out and focus of 81:

18*3=81 we leave out 3:

3*6=18 we leave out 3 again:

3*2=6

so our answer is 2*2*3*3*3 which in index form is 2²*3³ as there are two 2s and three 3s.

A. What are the coordinates of the vertices of the triangle below?

Viktor [21]

Answer:

Solution given:

<u>A.coordinate are</u>

A(-2,3)

B(0,-3)

C(4,5)

<u>B</u><u>.</u><u>Each</u><u> </u><u>length</u><u> </u><u>are</u><u> </u><u>:</u>

we have

length $\sqrt{(x2-x1)²+(y2-y1)²}$

now

AB: $\sqrt{(-2-0)²+(3+3)²}$ = $2\sqrt{10}$ units

BC: $\sqrt{(0-4)²+(-3-5)²}$ = $4\sqrt{5}$ units

AC: $\sqrt{(-2-4)²+(3-5)²}$ = $2\sqrt{10}$ units

<u>C.</u><u> the </u><u>figure</u><u>:</u>

<u>By</u><u> </u><u>using</u><u> </u><u>Pythagoras</u><u> </u><u>law</u>

base[b]=AB=perpendicular [p]=AC

hypotenuse [h]=BC

we have

h²=p²+b²

substituting value

( $4\sqrt{5}$ )²=2p²

16*5=2*( $2\sqrt{10}$ )²

80=2*4*10

80=80

<u>SO</u><u> </u><u>IT</u><u> </u><u>IS</u><u> </u><u>RIGHT</u><u> </u><u>ANGLED</u><u> </u><u>ISOSCELES</u><u> </u><u>TRIANGLE</u><u>.</u>
