Answer:

314 in²

Step-by-step explanation:

The formula for the area of a circle is pi*r² or pi (3.14...)* radius²(squared).

If you plug in the radius given into the equation, you get 3.14*10²  you can then solve this using systems of equations.

3.14*10²

10² = 10*10

3.14*(10*10)

10*10= 100

3.14*100

3.14*100= 314

Answer:

Angle 8=115 degrees

Angle 2= 65 degrees

Angle 6 + angle 7 = 65+65 = 130 degrees

Angle 3 + angle 5 = 180 degrees

Step-by-step explanation:

Answer:

The prime factors are: 2 x 2 x 2 x 3 x 7 x 7 x 13

Step-by-step explanation:

The domain is the set of all the x-values/inputs used by the function.  

The range is the set of all y-values/outputs used by the function.

For #1:

The domain is { 1, 0, -1, 4 } because those are the x-values.

The range is { 3, 5, 7, -6 } because those are the x-values.

I'll let you try #2.  if you write back with your answer, I'll reply to let you know if you did it correctly.

Answer:

1/2 = r

Step-by-step explanation:

7r + 21 = 49r

Subtract 7r from each side

7r-7r + 21 = 49r-7r

21 = 42r

Divide each side by 2

21/42 = 42r/42

1/2 = r

Answer:

r = 0.5

Step-by-step explanation:

First you need to isolate the r variable.

7r + 21 = 49r

-7r          -7r

21 = 42r

Then Divide both sides by 42

0.5 = r

Now check your answer by inserting it back into the original equation.

7(0.5) + 21 = 49(0.5)

3.5 + 21 = 24.5

24.5 = 24.5

The equation is true so r = 0.5

To multiply numbers or expressions means that we calculate the product of the numbers or expressions. The value of [tex]-0.5 \times (-0.4)[/tex] is [tex]0.2[/tex]

Given that:

[tex]-0.5 \times (-0.4)[/tex]

Cancel out the negative signs

[tex]-0.5 \times (-0.4) = 0.5 \times (0.4)[/tex]

Using a calculator, we have:

[tex]-0.5 \times (-0.4) = 0.2[/tex]

Hence, the value of [tex]-0.5 \times (-0.4)[/tex] is [tex]0.2[/tex]

Answer:

15/2 or 7.5

Step-by-step explanation:

Distance = 6 - (-3)/2

Distance = 6 + 3/2

Distance = 12 + 3/2

Distance = 15/2 or 7.5

[tex] \sin(60 - \theta) \sin(60 + \theta) \\ = \{ \sin(60) \cos( \theta) - \sin( \theta) \cos(60) \} \{ \sin(60) \cos( \theta) + \cos(60) \sin( \theta) \} \\ = \{ \frac{ \sqrt{3} }{2} \cos( \theta) - \frac{1}{2} \sin( \theta) \} \{ \frac{ \sqrt{3} }{2} \cos( \theta) + \frac{1}{2} \sin( \theta) \} \\ \\ [/tex]

from difference of two squares:

[tex]{ \boxed{(a - b)(a + b) = ( {a}^{2} - {b}^{2} ) }}[/tex]

therefore:

[tex] = \{ {( \frac{ \sqrt{3} }{2}) }^{2} { \cos }^{2} \theta \} - \{ {( \frac{ \sqrt{3} }{2} )}^{2} { \sin }^{2} \theta \} \\ \\ = \frac{3}{4} { \cos }^{2} \theta - \frac{3}{4} { \sin}^{2} \theta[/tex]

factorise out ¾ :

Answer:

m = -1/2

Step-by-step explanation:

4 − 2 = 12

= −2 = 12 − 4

= = (12 − 4) ÷ (−2)

= = 2−6

So, the slope is 2.

Now, keep this rule in mind: the product of a slope of two perpendicular lines will be -1.

Thus, the slope of the line that is perpendicular to this line is -1/2

Step-by-step explanation:

You need to find the HCF of 36 and 90.

Prime factors of each:

HCF includes all prime factors of both numbers:

To find the least number,

Which is exactly divisible by 36 and 90. We have to find the HCF of 36 and 90.

→ 36 = 2 × 2 × 3 × 3

→ 90 = 2 × 3 × 3 × 5

Then the required HCF will be,

→ 2 × 2 × 3 × 3 × 5

→ 180 (HCF)

Thus, 180 is the least number which is exactly divisible by 36 and 90.
