When point E (-9, 3) is rotated 180� about the origin, its coordinate becomes (3, 9).

1 answer:

5 0

The statement "<span>When point E (-9, 3) is rotated 180� about the origin, its coordinate becomes (3, 9)." is FALSE.

The answer should be (9,-3) because when a point is rotated 180 degrees about the origin, its coordinates change signs.

2(2/5) divided 2(-1/5)

we do PEMDAS meaning parenthesis first

2(2/5) = 4/5(calculator)

2/1x2/5=4/5

now

2/1x-1/5=-2/5

now we do division

4/5/-2/5 we get -2

Show me step by step multiplication on how to answer : 1 2/5 x 1/4

Phantasy [73]

Answer:

Step-by-step explanation:

What i would do is turn the first one into an improper fraction

7/5 x 1/4

it's easier to multiply this way

see if you can simplify any of the terms first

7 1

5 4

none of the numbers can be broken down further so we just multiply straight across

7 x 1 is 7

5 times 4 is 20

so the answer would be 7/20

If the aorta (diameter of da) branches into two equal-sized arteries with a combined area equal to the aorta, what is the diamet

kompoz [17]

If each of the branches has half the area of the aorta, its linear scale factor is the square root of 1/2, or (√2)/2.

The diameter of one of the branches is (da×√2)/2.

Solve for m.<br> m/9 + 2/3 =7/3

Nuetrik [128]

Answer:

m= 15

Step-by-step explanation:

$\frac{m}{9} + \frac{2}{3} = \frac{7}{3}$

To solve for m, start by moving the constants (numbers that are not attached to any variable) to the other side of the equation.

$\frac{m}{9} = \frac{7}{3} - \frac{2}{3}$

Simplify:

$\frac{m}{9} = \frac{5}{3}$

Multiply both sides by 9:

$m = \frac{5}{3} \times 9$

Crossing out 3 from the denominator and from 9:

m= 5(3)

m= 15
