This would be a 90° arc.

To find this, we can find the measure of the central angle that intercepts the arc.

The endpoints of the arc are at (9, -3) and (4, 2).

The slope of the line that passes through the endpoint (9, -3) and the center (4, -3) is given by

m=(-3--3)/(9-4) = 0/5 = 0.

Since the slope is 0, this tells us it is a horizontal line.

The line that passes through the endpoint (4, 2) and the center (4, -3) has a slope that is undefined; it is a vertical line at x=4. Numerically the slope is given by

m=(2--3)/(4-4) = 5/0, which is undefined.

These slopes are negative reciprocals of one another; 5/0 and 0/5 (0 has no sign). This means that these two lines would form a right angle, so the central angle of the circle is a right angle.

The intercepted arc has a measure equal to that of the central angle, so the arc is also 90°.

Question

Is y=-13/6x+5/3 same as 13x+6y=10 ?

Solution 1

Yes:

13x + 6y = 10

-13x -13x

_______________

6y = -13x + 10

Divide 6y, 13x, and 10 by 6

y = -13/6x + 10/6

Simply 10/6 by finding the least common multiple of the numerator and denominator, which is 2. 10 divided by 2 is 5, and 6 divided by 2 is 3. 10/6 = 5/3

Solution:

y = -13/6x + 5/3

13x + 6y = 10

-13x -13x

_______________

6y = -13x + 10

Divide 6y, 13x, and 10 by 6

y = -13/6x + 10/6

Simply 10/6 by finding the least common multiple of the numerator and denominator, which is 2. 10 divided by 2 is 5, and 6 divided by 2 is 3. 10/6 = 5/3

Solution:

y = -13/6x + 5/3

Question

Help How much will $5,000 invested at 6% compounded annually amount to after 10 years?

Solution 1

To find one year, here's the equation:

5000 + 0.06(5000)

For 10 years:

5000 + 10(0.06(5000))

Multiply:

5000 + 0.6(5000)

We can make it smaller:

1.6(5000) = 8000

**You can make $8000**

5000 + 0.06(5000)

For 10 years:

5000 + 10(0.06(5000))

Multiply:

5000 + 0.6(5000)

We can make it smaller:

1.6(5000) = 8000

Question

What does 3P2 equal?

Solution 1

No one has mentioned, so I will. What you are looking for is the permutation of 3 things taken 2 at a time. In other words, how many different unique ways are there to arrange 3 items, say colored balls, taking 2 of them for each group. By unique, I mean that 1 red and 1 blue is the same as 1 blue and 1 red,

Question

Solve the equation 2 cos x + 1 = 0 , 0 <= x <= 2pi PLEASE HELP! WILL AWARD!

Solution 1

It would be pi over 6, 5 pi over 6, and 3 pi over 6.

Solution 2

Im not saying its right but I got 0,2π3,4π3,and2π f(x)=2cos2x−cosx−1=0

Solve this quadratic equation for cos x.

Since a + b + c = 0, use shortcut.

One real root is cos x = 1 and the other is cosx=ca=−12.

Trig table and unit circle -->

a. cos x = 1 --> arc x = 0, and arc x=2π

b. cosx=−12 --> arc x=±2π3

The arc −2π3 is co-terminal to the arc: 4π3

Question

How many times do 12 go into 30

Solution 1

2 times with 6 left over because you would see how many times without going over and that would be 2 because 2x12 equals 24 amd 3x12 equals 36 bit that is ocer thirty then 30-24 equals 6. 6 is your remainder. Your full answer is 2 r4

Question

determine the amount of an investment if $400 is invested at an annual interest rate of 7.25% for 7 years. round to the nearest penny.

Solution 1

Equation for one year:

0.0725(400)

But we have 7 years:

7(0.0725(400))

Multiply in the parentheses

7(29) = 203

400 + 203 = 603

**You now have $603, and made $203**

0.0725(400)

But we have 7 years:

7(0.0725(400))

Multiply in the parentheses

7(29) = 203

400 + 203 = 603

Question

The equation for a projectile's height versus time is h(t)=-16t^2+Vt+h. A tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an initial speed of 130 feet per second. Which equation correctly models the ball's height as a function of time?

Solution 1

The** maximum height** at the moment is **266.0625 ft**.

The **equation for a projectile's height** versus time is

h = 2

V = 130

Substitute these values into the function

Take the first derivative

Equate the derivative with zero .

Solve the equation -32 t + 130=0

32 t = -130

t = -130 /(-32)

= 4.0625(s) .

Find the **maximum height** at the moment

t = 4.0625 (s)

h(4.0625)

= - 264.0625+528.125+2

= 266.0625 ft.

Therefore, the** maximum height** at the moment is **266.0625 ft**.

To learn more about **projectile's height**

#SPJ2

Solution 2

For this case we must use the projectile equation for this problem.

We have then:

h (t) = - 16t ^ 2 + Vt + h

Where,

V: initial speed

h: height

For the tennis ball we have:

h (t) = - 16t ^ 2 + 130t + 2

**Answer:**

**An equation that correctly models the ball's height as a function of time is:**

**h (t) = - 16t ^ 2 + 130t + 2**

We have then:

h (t) = - 16t ^ 2 + Vt + h

Where,

V: initial speed

h: height

For the tennis ball we have:

h (t) = - 16t ^ 2 + 130t + 2

Question

Juan Ramirez sells suits in a major department store on weekends. He earns a commission of 5% on the first 10 suits he sells. If he sells more than 10, he earns another 3% on the additional suits. Last weekend Juan sold 13 suits priced at $250 each. What was his commission? A. $185.00
B. $260.00
C. $147.50
D. $210.40

Solution 1

C. $147.50

the first 10 suits would sell at 250 each totaling 2500 which means he earns 5% of $2500, which is 0.05 x 2500 = $125. The next 3 suits which also sold at 250 which totals $750, he makes 3% of that amount which is 0.03 x 750 = $22.50. Together is makes 125 + 22.50 = $147.50 in commission.

Question

URGENT!!!! 100 POINTS!!! Data is shown from a random selection of bamboo plants on a bamboo farm. The number of days since the plant appeared above the soil and the height of the plant are shown. Days Since Plant Showed Above Soil l Height of Bamboo Plant in Centimeters
2 l 6.5
10 l 35.2
12 l 39.9
8 l 26.4
5 l 18.5
17 l 59.4
7 l 26.6
26 l 91.3
23 l 83.1

18 l 65.0
15 l 52.7
Which of the following lines of best fit represent the data if x is the number of days since the plant appeared and y is the height of the plant? (You might/might not need to make a scatter plot! Depends on the understanding of the question.)
y = –3.5x + 0.7
y = –0.7x + 3.5
y = 0.7x + 3.5
y = 3.5x + 0.7

Solution 1

Y=3.5x+0.7 is the answer.
