Answer:
A (-7, 1) = (X1, Y1)
B (3, -5) = (X1, Y2)
Now,
Mid point = (X1 + X2÷2, Y1 + Y2 ÷ 2)
= {-7+3÷2, 1+(-5)÷2}
= (-4÷2, 1-5÷2)
= (-4÷2, -4÷2)
= (-2, -2)
Step-by-step explanation:
I hope it will help you to study.
Evaluate : 2a^2+3b^3-10
For a=2 and b=(-2)
Step-by-step explanation:
Just substitute the values of a and b
2a^2 + 3b^3 - 10
2x2^2 + 3 x (-2)^3 - 10
= 2 x 4 + 3 x (-8) - 10
= 8 - 24 - 10
= 8 - 34
= -26
Answer:
- 26
Step-by-step explanation:
Given
2a² + 3b³ - 10 ← substitute a = 2, b = - 2 into the expression
= 2(2)² + 3(- 2)³ - 10
= 2(4) + 3(- 8) - 10
= 8 - 24 - 10
= - 16 - 10
= - 26
Show that the equation x^3+4x=6 has a solution between 1.1 and 1.2
plz I need help my dudes I have no clue what I’m doing
Answer:
see explanation
Step-by-step explanation:
If there is a solution between x = 1.1 and x = 1.2 then there will be a change in sign when the equation is evaluated at the points, indicating the graph has crossed the x- axis, where the solution lies.
Given
x³ + 4x = 6 ( subtract 6 from both sides )
x³ + 4x - 6 = 0 ← in standard form
Evaluating for x = 1.1
(1.1)³ + 4(1.1) - 6
= 1.331 + 4.4 - 6 = - 0.269 ← < 0
Evaluating for x = 1.2
(1.2)³ + 4(1.2) - 6
= 1.728 + 4.8 - 6 = 0.528 ← > 0
Since there is a change in sign the graph has crossed the x-axis from below / indicating a solution between x = 1.1 and x = 1.2

Answer:
θ = 85.93° (≈ 86°)
Step-by-step explanation:
arc length : 2πr = θ : 360°
7.5 : 2πr = θ : 360°
θ = (7.5 * 360°) / (2π*5) = 2700 / 31.42 = 85.93°
θ ≈ 86°
A letter is chosen at random from the letters of the word ASSASSINATION, then the probability that the letter chosen is a vowel is in the form of 6/2x+1, then find x.
Step-by-step explanation:
In the word "Assassination",
there are 13 letters in total and 6 vowels.
Probability of picking a vowel = 6/13.
Since 6/(2x + 1) = 6/13, 2x + 1 = 13, x = 6.

Answer:
Step-by-step explanation:
Stacy is measuring milk to make pancake batter. The recipe calls for \dfrac{3}{4} 4 3 start fraction, 3, divided by, 4, end fraction of a jug of milk. She has \dfrac{1}{4} 4 1 start fraction, 1, divided by, 4, end fraction of a jug now. How much more milk does she need?
Answer:
1/2 cup of milk
Step-by-step explanation:
Given
Total cup of milk needed = 3/4 cup of milk
Amount she has = 1/4 cup of milk
The amount of milk she needed = Total - Amount she has
Amount she needed = 3/4 - 1/4
Amount she needed = (3-1)/4
Amount she needed = 2/4
Amount she needed = 1/2
Hence she needs 1/2 cup of milk more

You are offered a job as a sales professional. You are offered a monthly base (fixed) salary of $1,000 plus 30% of the total sales you make for the month.
1) Write a linear function that represents your monthly income.
2) What is the slope? What does it mean in this context?
3) What is the y-intercept? What does it mean in this context?
4) BONUS (1 pt) If you sell $5,000 worth of product, what is your monthly income?
Answer:
1) y = 0.3x + 1000
2) slope = 0.3
The slope is the fraction of the monthly sales that is added to your salary.
3) y-intercept = 1000
The y-intercept is the fixed part of the salary, $1000.
4) The salary is $2500
Step-by-step explanation:
1)
monthly salary = fixed part + variable part
The fixed part is $1000. Every month you receive $1000 no matter the amount of sales.
The variable part varies according to the amount of sales. You get 30% of the of the monthly sales. Let the monthly sales be x. The variable part is 0.3x
Let the monthly salary = y.
y = 1000 + 0.3x
y = 0.3x + 1000
2)
slope = 0.3
The slope is the fraction of the monthly sales that is added to your salary.
3)
y-intercept = 1000
The y-intercept is the fixed part of the salary, $1000.
4)
In this case, x = 5000
y = 0.3x + 1000
y = 0.3(5000) + 1000
y = 1500 + 1000
y = 2500
The salary is $2500.

The teacher does not have to spend all $36. Write an inequality relating 36 and 9 (7 - x) representing this situation. (Copy/paste as needed: ≤ ﹤ ≥ ﹥)
Answer:
9(7-x) < 36Step-by-step explanation:
From the question, we are to relate the amount the teacher spent to the expression 9(7-x).
Since the teacher does not have to spend all the $36, this means that he spent amount less than $36 but not equal to $36. Hence the best inequality sign that relates both expression is a less than sign (<) as shown;
9(7-x) < 36
hence the required inequality is 9(7-x) < 36

I am just confused on how to do this question. A 37-inch TV is 37-inches diagonally across the screen. Which of these dimensions best describes a 37-inch TV? A. 15 x 34 B. 16.5 x 32 C. 17 x 28 D. 17 x 32
Given that,
A TV is 27 inch diagonally across the screen.
To find,
The dimensions that best describes a 37 inch TV.
Solution,
Let a and b are length and width of the TV. Let c be the diagonal. Using Pythagoras theorem,
[tex]c=\sqrt{a^2+b^2}[/tex]
If dimensions are 15 x 34,
[tex]c=\sqrt{15^{2}+34^{2}}\\\\=37.16\ inch[/tex]
If dimensions are 16.5 x 32,
[tex]c=\sqrt{16.5^{2}+32^{2}}\\\\=36.003\ inch[/tex]
If dimensions are 17 x 28,
[tex]c=\sqrt{17^{2}+28^{2}}\\\\=32.756\ inch[/tex]
If dimensions are 17 x 32,
[tex]c=\sqrt{17^{2}+32^{2}}\\\\=36.23\ inch[/tex]
It is clear that if dimensions are 15 x 34, the diagonal is 37 inches. Hence, the correct option is (a).
