Test the function x-y²=0 for symmetries.

Mathematics
1 answer:
mafiozo [28]2 years ago
4 0

For Symmetry About Y-Axis, let's try to replace x with −x, and check if the equations still equal:

-x - y² = 0

The equation changed, so there is no symmetry about Y-Axis.

For Symmetry About X-Axis, let's try to replace y with −y, and check if the equations still equal:

x - (-y)² = 0

x - y² = 0

The equation stayed the same, so there is a symmetry in X-Axis.

Lets try Origin Symmetry Replacing x with −x and y with −y:

-x - (-y)² = 0

-x - y² = 0

The equation changed, so there is no Origin Symmetry.

Answer:

8 × 10¹

Step-by-step explanation:

don't panic. just breathe deeply and then think logically.

0.002 ... what is that ? 2 10ths ? 2 hundredths ? 2 thousandths ? 2 tenthousandths ?

the 3rd position after the decimal point is for 1/1000.

and that means 10^-3. in the same way as 1000 is 10³.

so, it is 2 × 10^-3.

the other rounded number is then 4 × 10⁴.

now, we are multiplying both numbers

2×10^-3 × 4×10⁴

what do we do ?

we combine the same types of factors, like the basic constants : 2×4 = 8

and 10^-3 × 10⁴.

what hairball when we multiply the same base number with exponents ? we add the exponents :

10^-3 × 10⁴ = 10¹ = 10

because -3 + 4 = 1

and so, the result is

8 × 10¹

Imran deposited 3000 per month (at the start of month) into a saving account for 10 months. If the bank offer 6% interest compou
AnnZ [28]

Answer:

3.590.04

Step-by-step explanation:

The formula given for total amount saved when compounding interest =

A = P(1 + r/n)^nt

Where

A = Total amount saved after t years

P = Principal or initial amount saved

r = Interest rate

n = compounding frequency

t = time in years

From the above question

P = 3000

r =6% = 0.06

n =compounded monthly = 12

t = 3 years

Hence,

A = 3000(1 + 0.06/12)^3 × 12

A = 3000(1 + 0.06/12)^36

A = 3,590.04

Therefore, the total amount Imran will have in his account after 3 years = 3,590.04

Which steps could be used to solve this equation?
Nesterboy [21]

Answer:

answer is option B

Step-by-step explanation:

ok the equation is 2/3 x +9 = 15

if we substract 9 from both sides it becomes, 2/3x +9-9 = 15-9.

2/3x = 6

now if we multiply both sides by the reciprocal of 2/3 ( reciprocal means flip it for example receprocal or 2/3 is 3/2)

we multiply both side by reciprocal ie,

2/3 x 3/2 which is 1 because the 3 on the numerator cancels with the 3 on the deniy and the 2 on the numerator cancels with 2 on the denominator. then you are left with only x on the left side.

x = 6 x 3/2 = 18/2 = 9.
