Pie r squared is the area of a circle, so 9^2(3.14etc) = so 255 square yards. So 255 x 15 = $3,825

Answer:

x+7

Step-by-step explanation:

So it's been a while since I took Geometry, so I don't know what principle makes these angles equal to each other, but I know that they are in fact equal. So that means that 6x +3 = 45. Subtract 3 from each side gets you 42+6x, then divide each side by 6, which gets you your answer of x=7.

Find the slope of the line passing through the given points.
deff fn [24]

Answer:

<h3>The answer is - 3</h3>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

From the question we have

m =  \frac{8 - 5}{ - 8 -  - 7}  =  \frac{3}{ - 8 +7 }  =   - \frac{3}{1}  =  - 3 \\

We have the final answer as

<h3>- 3</h3>

Hope this helps you

Ms. Thomas is saving up to buy a new phone. She has already saved $200 and adding $50 per month to her saving account. She wants
melomori [17]

Answer:

Step-by-step explanation:

The inequality equation can be determined by using the concept of arithmetic progression;

a(n) = a₁ + (n-1)d

where;

a(n) = 1000

a = 200

d = 50

The inequality will be:

1000 = 200 + ( n - 1) 50

1000 = 200 + 50n - 50

1000 = 150 + 50 n

1000 - 150 = 50 n

850 = 50 n

n = 850/50

n = 17 months

So, if Ms. Thomas is planning to have more than $1000 in her account, she will need to save for 17 moths before she can buy the phone.

Can a cubic equation have 3 complex roots? 3 real roots? ...?
trasher [3.6K]
No, a cubic equation can not have three complex roots. This is because it turns twice and one end goes to positive infinity and one end goes to negative infinity. Thus, one of these MUST cross the x-axis at some point, meaning y = 0 and a real root exists.

Yes, a cubic equation can have three real roots if it cuts the x-axis three times.
