Given directed line segment PR below, find the coordinates of Q on PR
such that the ratio of PQ to QR is 2:1.
Answer:
[tex](\frac{4}{3},-3)[/tex]
Step-by-step explanation:
The location of a point O(x, y) which divides line segment AB in the ratio a:b with point A at ([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2[/tex]) is given by the formula:
[tex]x=\frac{a}{a+b}(x_2-x_1)+x_1\\ \\y=\frac{a}{a+b}(y_2-y_1)+y_1[/tex]
From the graph, the location of the point is P(2, 5), R(1, -7). Let point Q be (x, y) which divides PR in ratio 2:1. Coordinates of point Q is at:
[tex]x=\frac{a}{a+b}(x_2-x_1)+x_1=\frac{2}{2+1}(1-2)+2=\frac{2}{3}(-1)+2=\frac{4}{3} \\ \\y=\frac{a}{a+b}(y_2-y_1)+y_1=\frac{2}{2+1}(-7-5)+5= \frac{2}{3}(-12)+5=-3[/tex]
Point Q is at [tex](\frac{4}{3},-3)[/tex]
perform the indicated operation. 2i(3-4i)+8(4-5i)(4+5i)
Answer: 336+6i
The key to solving this problem is to choose which parts you should solve first.
2i(3-4i)+8(4-5i)(4+5i)
let's divide this expression to three parts:
2i(3-4i), 8 and (4-5i)(4+5i)
first let's solve 2i(3-4i):
2i(3-4i) =
2i × 3 + 2i × -4i =
6i - 8i² =
6i + 8
(4-5i)(4+5i):
(4-5i)(4+5i) =
16 + 20i - 20i -25² =
16 + 25 =
41
8(4-5i)(4+5i):
8(4-5i)(4+5i) = 8 × 41 = 328
Now let's put back these parts:
2i(3-4i)+8(4-5i)(4+5i) =
6i + 8 + 328 =
6i +336 OR 336 +6i
A ball flies through the air. Right before it hits the ground, its speed is 10 meters/second and it has 500 joules of kinetic energy. The mass of the ball is kilograms.
Answer:
10 kg
Step-by-step explanation
Explanation:
Kinetic Energy = 1/2 * M (V square )
M is mass and V is velocity of the ball
500J = 1/2 *M *( 10)*(10)
M = 10 kg
Answer:
10 kg
Step-by-step explanation:
Formula for the kinetic energy:
½mv²
Find the mass:
= ½ × m × 10² = 500 joules
= 50 × m
m = 500 ÷ 50
m = 10 kg
The answer is 10 kg.

Employees in 2012 paid 4.2% of their gross wages towards social security (FICA tax). How much will someone earning $43,047 a year pay towards social security?
Answer:
$1807.94
Step-by-step explanation:
Given that:
Annual income = $43047
Social security (FICA tax) = 4.2% of the gross wages
To find:
Social security paid = ?
Solution:
Social security (FICA tax) is calculated by finding the 4.2% of the Total Gross Annual income.
i.e. for the given value, the social security paid can be calculated as:
4.2% of $43047
[tex]\Rightarrow \dfrac{4.2}{100}\ of \ \$43047\\\Rightarrow \dfrac{42}{1000}\times 43047\\\Rightarrow 0.042\times 43047\\\Rightarrow \bold{\$1807.97}[/tex]
Therefore, the Social Security paid is $1807.94.

Answer: $39.60
Step-by-step explanation:
Here is the correct question:
Christopher has breakfast at a cafe and the cost of his meal is $36.00 . because of the service he wants to leave a 10% tip.What is his total bill including tip?
His total bill will be the addition of the cost of his meal and the tip. This will be:
= $36.00 + (10% × $36.00)
= $36.00 + $3.6
= $39.60
His total bill including tip is $39.60

Michael solved this inequality as shown: Step 1: -6(x + 3) + 10 < -2 Step 2: -6x − 18 + 10 < -2 Step 3: -6x − 8 < -2 Step 4: -6x < 6 Step 5: x > -1 What property justifies the work shown between step 3 and step 4? A. transitive property B. division property of inequality C. distribution property D. addition property of inequality
Answer:
D. addition property of inequalityStep-by-step explanation:
Given the step 3 and 4 of the solution Step 3: -6x − 8 < -2 Step 4: -6x < 6
From step 3;
-6x − 8 < -2
Michael got the step 4 by adding 8 to both sides of the inequality as shown;
-6x − 8 + 8 < -2 + 8
-6x < 6 (Step 4)
Since Michael added 8 to both sides of the inequality, the property that justifies the transition from step 3 to step 4 is the addition property of inequality. Addition property is the property that adds an integer to both sides of an inequality without altering the inequality sign and also retaining the inequality equation.

During a science experiment, Daniel noted the starting temperature of a At the end of the experiment, the change in temperature was What was the final temperature?
Complete question :
During a science experiment, Daniel noted the starting temperature of a -4°F. At the end of the experiment, the change in temperature was -5°F. What was the final temperature?
A.-1 B.1 C.9 D.-9
Answer:
D.) - 9
Step-by-step explanation:
Given the following :
Temperature at the start of experiment = - 4°F
At the end of experiment, change in temperature = - 5°F
This means between the temperature at the start of the experiment was - 4°F and during the cause of the experiment, there was a change in temperature of - 5°F.
Hence, the final temperature is the sum of the initial temperature and and the temperature change recorded.
Initial temperature + temperature change
-4°F + (-5°F)
- 4°F - 5°F = - 9°F
Hence, final temperature = - 9°F
Answer:
The answer is 9
Given the following :
Temperature at the start of experiment = - 4°F
At the end of experiment, change in temperature = - 5°F
This means between the temperature at the start of the experiment was - 4°F and during the cause of the experiment, there was a change in temperature of - 5°F.
Hence, the final temperature is the sum of the initial temperature and and the temperature change recorded.
Initial temperature + temperature change
-4°F + (-5°F)
- 4°F - 5°F = - 9°F
Hence, final temperature = - 9°F

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
3 x 3 x 3 x 3
The form to write an exponential expression.

Now,
There are four 3's and we can write it as an exponent form where the base is 3 and the exponent is 4.

Step-by-step explanation:
What is the value of x?
Answer:
x = 24
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
a = a leg
b = another leg
c = hypotenuse
Step 1: Plug in known variables
x² + 10² = 26²
Step 2: Evaluate
x² + 100 = 676
Step 3: Isolate x term
x² = 576
Step 4: Isolate x
√x² = √576
x = 24
Answer:
[tex]x=24[/tex]
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean Theorem.
The Pythagorean Theorem is:
[tex]a^2+b^2=c^2[/tex]
The hypotenuse is c, and the legs are a and b.
Plug in 26 for c since 26 is the hypotenuse, and let 10 for a and x be b. Therefore:
[tex]x^2+10^2=26^2[/tex]
Square:
[tex]x^2+100=676[/tex]
Subtract 100 from both sides:
[tex]x^2=576[/tex]
Take the square root of both sides:
[tex]\sqrt{x^2}=\sqrt{576}\\x=\sqrt{576}=24[/tex]
The answer is 24.
