What is the angle of rotation of the minute hand of a clock moving from 6:10 to 7:00?

2 answers:

5 0

Because the movement of the minute han of a clock is clockwise ↓, then the angle of rotation will be negative.

1) we calculate the number of minutes from 6:10 to 7:00

number of minutes=7:00-6:10=6:60 - 6:10=50 minutes.

2)
We know that:
60 minutes of a clock have turned -360º
Then:

60 minutes of a clock------------------------- -360º
50 minutes of a clock------------------------- x

x=(50 minutes of a clock * (-360º))/60 minutes of a clock=-300º

Answer: A. -300º

What are the zeros of the function f(x) = x2 + 5x + 5 written in simplest radical form?

Pavel [41]

$\boxed{x_{1}=\frac{-5 + \sqrt{5}}{2}} \\ \\ \\ \boxed{x_{2}=\frac{-5 - \sqrt{5}}{2}}$

<h2>Explanation:</h2>

Using the quadratic formula:

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ \\ Here: \\ \\ f(x) = x^2 + 5x + 5 \\ \\ \\ So: \\ \\ a=1 \\ \\ b=5 \\ \\ c=5 \\ \\ \\ x=\frac{-5 \pm \sqrt{5^2-4(1)(5)}}{2(1)} \\ \\ x=\frac{-5 \pm \sqrt{25-20}}{2} \\ \\ x=\frac{-5 \pm \sqrt{5}}{2} \\ \\ \\ Two \ solutions: \\ \\ \boxed{x_{1}=\frac{-5 + \sqrt{5}}{2}} \\ \\ \\ \boxed{x_{2}=\frac{-5 - \sqrt{5}}{2}}$

A city has a population of 250,000 people. Suppose that each year the population grows by 6%. What will the population be after

irinina [24]

Answer:

503,049

Step-by-step explanation:

250,000 × 1.06^12 is the formula.

You take the percentage which is 6% and you add 1 to it.

So, you get 1.06

Then you take the 1.06 and raise it to the number of years which is 12.

1.06^12

Then you multiply that number to the base number which is 250,000 and get 503,049.

Hope this helps!

Find x.<br> 8x + 11<br> 12x - 1

ELEN [110]

Answer:

x = 3

Step-by-step explanation:

If T is the midpoint, that means segments ST and TU are congruent.

Step 1: Set up expression

8x + 11 = 12x - 1

Step 2: Solve

11 = 4x - 1

12 = 4x

x = 3
