Rule: Any positive number is always larger than any negative number.

For example, 10 is larger than -2. So we write 10 > -2.

The same goes for 8 & 1/4 vs -8 & 1/4. It doesn't matter if we involve fractions or decimals.

Visually, positive numbers are to the right of 0 on the number line. Negative numbers are to the left of 0.

Stuff on the right is larger than stuff on the left.

Step-by-step explanation:

When you plot both those numbers on a number line, 8 ¼ will be on the right of the zero, and -8¼ will be on the left. The numbers on the right of zero are +ve and numbers on the left of zero are -ve. +ve numbers are always greater than -ve numbers, so 8¼ > -8¼!

What are the sizes of x , y and z
Fiesta28 [93]

Answer:

x=70°

y=30°

z=20°

Step-by-step explanation:

You first need to find y, which would be 30 because the sum of the first two angles is 150, and a triangle has 180 degrees, so 180-150=30.

By finding y, we can now find a, because if you take the entire triangle, y+z must equal 50. So, z=20 because 30+z=50.

And finally, we can find x to be 70 since the sum of the two other angles is 110 and 180-110=70.

If the sin 90 = 1 , then the cos 0 =
fenix001 [56]

Rule of trigonometric functions:-

sin a = cos(90 - a)

Here a = 90°.

sin 90 = cos (90 - 90)

1 = cos 0.

cos 0 = 1.


So the cos 0 = 1.

Radha purchased a cosmetic item at 5 % discount. If she got the discount amount of
Fiesta28 [93]

Answer:

She purchased the item at a price of Rs 1,406.

Step-by-step explanation:

5% of discount:

This means that she paid 100% - 5% = 95% = 0.95 of the original price of x, that is, 0.95x, and 0.05x was the discount.

Original price:

She got the discount amount of Rs 74.

74 is 5% of the original price, that is:

0.05x = 74

x = \frac{74}{0.05}

x = 1480

What price she purchased:

74 subtracted from the original price, that is, x - 74. So 1480 - 74 = 1406.

She purchased the item at a price of Rs 1,406.

X-intercept and y-intercepts og y=x^2-3
Rufina [12.5K]

Answer:

Part 1) The y-intercept is the point (0,-3)

Part 2) The x-intercepts are the points (-\sqrt{3},0)\ and\ (\sqrt{3},0)

Step-by-step explanation:

we have

y=x^{2}-3

This is a vertical parabola open upward

step 1

Find the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

y=(0)^{2}-3

y=-3

The y-intercept is the point (0,-3)

step 2

Find the x-intercepts

we know that

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

x^{2}-3=0

solve for x

Adds 3 both sides

x^{2}-3+3=0+3

x^{2}=3

take square root both sides

x=(+/-)\sqrt{3}

so

The x-intercepts are the points (-\sqrt{3},0)\ and\ (\sqrt{3},0)
