Answer:
[tex](-4, -\frac{1}{2})[/tex]
Step-by-step explanation:
Hi there!
We are given the line segment, with the end points AB
The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).
We want to find the midpoint of the line segment AB
The midpoint formula is given as [tex](\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are coordinates
We have two coordinates, which is what we need, but let's label their values to avoid any confusion:
[tex]x_1=-5\\y_1=-4\\x_2=-3\\y_2=3[/tex]
Now substitute those values into the formula:
[tex](\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})[/tex]
[tex](\frac{-5+ -3}{2}, \frac{-4+ 3}{2})[/tex]
Now simplify the numerator and denominator
[tex](\frac{-8}{2}, \frac{-1}{2})[/tex]
Simplify again:
The midpoint is (-4, [tex]-\frac{1}{2}[/tex])
Hope this helps!

What is the image point of (4, -12) after the transformation rx-axis o D 1/4?
Answer:
(4, 12) is the answer after being reflected over the x-axis
Step-by-step explanation:
=> The x remains the same, the y flips over the x - to be negative
(4, -12) ==>> (4, 12)
--
=> The new point after being reflected over the x-axis is (4, 12) in which is the answer
(4, 12) ==>> Final Solution (Correct)

What is the image of the point (7,4) after a rotation of 90° counterclockwise about
the origin?
Answer:
When rotating a point 90 degrees counterclockwise about the origin the point (7,4) becomes (-4,7).
Step-by-step explanation:
In other words, just switch x and y and make y negative.
The point will be inverted when (7,4) is rotated 90° counterclockwise i.e., the new point will be (4,7).
It is given that a point (7,4) is rotated 90° counterclockwise about origin.
We have to find the new point after rotation.
What do you mean by rotation counterclockwise ?
If something is moving counterclockwise that meant it is moving in the opposite direction to the direction in which the hands of a clock move.
As per the question ;
A point (7,4) is rotated of 90° counterclockwise about origin.
Let's assume (7,4) = (x , y)
If we rotate it 90°counterclockwise ; then the point will be inverted ; i.e.,
(x , y ) ⇒ ( y , x)
So ;
( 7 , 4 ) = ( 4 , 7 )
So ;
The new point will be ;
= ( 4 , 7 )
Thus , the point will be inverted when (7,4) is rotated 90° counterclockwise i.e., the new point will be (4,7).

Answer:
√128 units
Step-by-step explanation:
As we move to the right from (-4, -2) to (4, 6), x increases by 8 and y increases by 8 also. Using the distance formula, we get:
d = √(8² + 8²) = √(64 + 64) = √128 units (last answer)
An elevator rises steadily up a skyscraper. After 4 s it is 33 m above the ground, 2 s later it is 47 m above the ground. Which equation models its position, y, with respect to time, x?
Answer:
The 2nd motion eqn.
S = ut + 1/2gt²
where, u is the initial speed of the elevator
S = position
and t = x
y = ux + 1/2gx²
y = 1/2gx² + ux
since the elevator started at 0 as initial speed(that is at rest)
y = 1/2gx² + 0
y = 1/2gx² is the eqn

A firm’s production function is
Q = 50L − 0.01L2
where L denotes the size of the workforce. Find the value of MPL in the case when
(a) L = 1 (b) L = 10 (c) L = 100 (d) L = 1000
The value of MPL for the various cases are;
A) MPL = 49.98
B) MPL = 49.8
C) MPL = 48
D) MPL = 30
We are given;
Q = 50L - 0.01L²
Now MPL means marginal product of labor and it is defined as the derivative of Q with respect to L. Thus;
MPL = dQ/dL = 50 - 2(0.01L)
A) When L = 1;
MPL = 50 - 2(0.01 × 1)
MPL = 49.98
B) When L = 10;
MPL = 50 - 2(0.01 × 10)
MPL = 49.8
C) When L = 100
MPL = 50 - 2(0.01 × 100)
MPL = 48
D) When L = 1000
MPL = 50 - 2(0.01 × 1000)
MPL = 30

An IQ test is designed so that the mean is 100 and the standard deviation is 10 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 8 IQ points of the true mean. Assume that σ=10and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is
Answer:
sample size = 10
it is not practical because we can't draw a conclusion for a complete population based on the sample size of 10 people
Step-by-step explanation:
mean = 100
standard deviation = sigma = 10
confidence level = 99%
The z-score for 99% confidence level = z = 2.58
mean IQ is within 8 IQ points so:
error = E = 8
sample size = n (we don't know it)
Since the distribution is normal, we can use the formula of margin of error for z-distribution to calculate the missing sample size:
[tex]E = z * \frac{sigma}{\sqrt{n} } \\\sqrt{n} = z * \frac{sigma}{E} \\\\\sqrt{n} = 2.58*\frac{10}{8} \\\\\sqrt{n} = \frac{25.8}{8} \\\\n = (\frac{25.8}{8} )^{2}\\n = 10.4\\[/tex]

let f(x)=2x^2+7x-5 and g(x)=-8^2-3x+5 what is g(x)+f(x)
Answer:
2x^2 + 4x - 64
Step-by-step explanation:
it is telling us to add the functions together so we use this equation:
2x^2 + 7x - 5 + (-8^2) - 3x + 5
after combining like terms we get
2x^2 + 4x -8^2
and then lastly we square the -8 and get
2x^2 + 4x - 64
A salesperson works 40 hours per week at a job where she has two options for being paid. Option A is an hourly wage of $22. Option B is a commission rate of 8% on weekly sales. How much does she need to sell this week to earn the same amount with the two options?
PLEASE HELP
Answer:
We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $25. Option B is a commission rate of 8% on weekly sales.
First of all we will find amount earned by salesperson with option A.
The salespersons earns $1000 through option A.
Let x be the amount of weekly sales.
8% of x should be equal to 1000 for salesman to earn the same amount with the two options.
Therefore, the salesman needs to make a weekly sales of $12,500 to earn the same amount with two options.We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid.

The domain of y = -2x + 7 is the set of all real numbers (assumed to be).
For each x real, the equation y = -2x + 7, means that exactly one real number is associated with x. Thus, it is a function. We note that a function is a special type of relation.
