Find an equation for the line tangent to the circle
x2 + y2 = 100
at the point
(8, −6).
Answers
Second, plot the point (-6,8) on the circle.
Third, draw a radius from the origin to this point. You should be able to determine the SLOPE of this radius. Since slope is -8/6, this reduces to -4/3.
Fourth, use the point-slope form to find the equation:
y - y1 = m ( x - x1)
y - 8 = -4/3 ( x - -6 )
y - 8 = -4/3 ( x + 6 ) This is the Point-Slope form of the equation.
Fifth, sometimes the question specifies the Slope-Intercept form of the equation. If that is the case, then you only have 2 steps left. First, distribute the -4/3 on the right side of the equation.
y - 8 = -4/3(x) + 8 Now, we isolate the "y" by adding 8 to both sides of the equation.

Paulette is paid 2 1/2 % commission on all sales, and an extra 1 1/2 % on all sales over $6,500. Her sales last week totaled $17,400. What were her total earnings for the week?
Answers
The total earnings in the form of commission for Paulette is $ 598.5.
Commission till sales of $ 6,500 = 2 1/2 %
So amount of commission will be
A = 5 / 200 × 17400
A = 5 / 2 × 174
A = $ 435
Extra commission:
E = 3 / 200 × ( 17400-6500)
E = 3 / 200 × 10900
E = 3 / 2 × 109
E = $ 163.5
Total commission = $ 435 + $ 163.5
T = $ 598.5
Therefore, the total earnings in the form of commission for Paulette is $ 598.5.

If 1 shoe equals 6.5 socks, how many socks are equivalent to 2.3 shoes?
Answers
The equivalent number of socks to 2.3 shoes is 14.95 socks
Ratio and proportionsFractions are expression written as a ratio of two integers. For instance If 1 shoe equals 6.5 socks, this can be written as:
1 shoe = 6.5 socks
In order to determine the number of socks for 2.3 shoes, we will have:
2.3 shoes = x socks
Determine the ratio
1/2.3 = 6.5/x
Cross multiply
1 * x = 2.3 * 6.5
x = 2.3 * 6.5
x = 14.95

Answers
For the given question options C, D and E are correct answers.
Given that, ∠2, ∠3, and ∠5 are interior angles of the triangle and ∠1, ∠4, and ∠6 are exterior angles of the triangle.
What are the exterior angles of a triangle?When any side of a triangle is extended, the angle that is formed with this side and its adjacent side is called the exterior angle of a triangle. There are three exterior angles in a triangle. It should be noted that each exterior angle forms a linear pair with its corresponding interior angle.
Now, m∠5 + m∠6=180° (Adjacent angles are added up to 180°)
m∠2 + m∠3 = m∠6 (Exterior angle is equal to the sum of opposite interior angles)
m∠2 + m∠3 + m∠5 = 180° (Sum of all the interior angles of a triangle is equal to 180°)
Therefore, options C, D and E are correct answers.

If the stylist needs to make 100 oz of dye, how much of each dye color is needed?
Answers
The answers to both the questions are as follows:
We need 3 ounces of red tone, 6 ounces of gray tone, and 5 ounces of a brown tone to make 20 ounces of dye.We need 15 ounces of red tone, 30 ounces of gray tone, and 25 ounces of a brown tone to make 100 ounces of dye.The quantity of specific hair dye produced by given ingredients are:
= 1(1/8) + 3/4 + 5/8= 9/8 + 3/4 + 5/8= (9+6+5)/8 = 20/8 = 5/2ozAs a result, the amount of specific hair dye produced by given ingredients = 5/2qz
To calculate the amount of each ingredient needed to make 1 oz of specific hair dye, multiply the reciprocal of 5/2 by each ingredient.The amount of red tone required to make 1 oz of a specific dye:
= 3/8 × 2/5 = 3/20 oz
Gray tone = 3/1 × 2/5 = 3/10 Oz Brown tone = 5/8 × 2/5 = 1/4 Oz=Now, multiply each by 20.
The amount of red tone required to make 20 oz of a specific dye:
3/20 × 20 = 3 oz
Gray tone = 3/10 × 20 = 6oz Brown tone = 1/4 × 20 = 5ozTo find each dye needed to make 100 ounces of dye, multiply the above amounts by 5.
(Since, 100 = 20 × 5)The amount of red tone required to make 20 oz of specific dye: 15oz
Gray tone is similar: 30 ozBrown tone is: 25 ozTherefore, the answers to both the questions are as follows:

When time equals 0, why is the temperature in the oven not equal to 0? Why does the temperature eventually oscillate around 350°F?
Answers
The ambient temperature, aka the outside air temperature, isn't 0 degrees Fahrenheit. This is the reason why the oven isn't at 0 degrees Fahrenheit when the oven is off. For example, if it is 68 degrees Fahrenheit outside, then the oven's temperature is likely around this figure when it is off.
------------------------------
The way the oven works is that it heats the air using a gas or electric source. Once reaching 350 or slightly higher, the oven burner will turn off for a set period of time. This is so the temperature doesn't go too far over 350.
After the burner is turned off, the air inside the oven is still really hot and will stay around 350 for a while. But the temperature will slowly decrease. Once dipping slightly below 350, the oven will turn back on to heat back up to 350 again. This process repeats over and over.
This explains why you see the oscillating bouncing curve like this. It also explains why ovens seem to go on or off in the middle of a baking session.

LCM of 8, 16 and 24
Decompose to prime factors
8/2 = 4; 4/2 = 2. So 8 = 2 x 2 x 2
16 = 8 x 2 = (2 x 2 x 2) x 2
24 = 8 x 3 = (2 x 2 x 2) x 3
2 x 2 x 2 is common, 2 appears once more as a factor in 16 and 3 appears in 24 so the LCM = (2 x 2 x 2) x 2 x 3 = 48
