Midpoint (0,-1)
ANSWER
[tex](0, - 1)[/tex]
EXPLANATION
The midpoint formula is given by:
[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
To find the midpoint of the segment joining A (3,4) and B (-3,-6), we substitute the points into the formula:
[tex](\frac{3+ - 3}{2},\frac{4+ - 6}{2})[/tex]
We simplify to obtain;
[tex](\frac{0}{2},\frac{ - 2}{2})[/tex]
This gives us;
[tex](0, - 1)[/tex]
The midpoint of line segment AB is (0,-1)

Final answer:
To find the total cost per mile to rent the car, add the rental cost for 5 days to the gasoline cost, then divide by the miles driven. Ruth Barr's total cost per mile was approximately $0.3785.
Explanation:
To calculate the total cost per mile to rent the car, we need to add the cost of renting the car for 5 days to the cost of gasoline and then divide the sum by the number of miles driven.
Calculate the rental cost for 5 days: 5 days × $59.95/day = $299.75.
Add the cost for gasoline: $299.75 (rental cost) + $137.76 (gasoline) = $437.51.
Divide the total cost by the number of miles driven: $437.51 ÷ 1156 miles = approximately $0.3785 per mile.
The total cost per mile Ruth Barr spent to rent the car was approximately $0.3785.
What is the measure of ced?
Answer:
212°
Step-by-step explanation:
We have the measure of CE and the measure of ED, so all we have to do is combine those two to get the measure of CED.
The arc CE measures 52 degrees.
The arc ED measures 160 degrees
The arc CED is the sum of arc CE and ED, so:
CED = 52° + 160° = 212°
We don't have any length measurement inside that circle to calculate the length of the arc CED in inches, centimeters or otherwise... so we can only measure it degrees.

5x=3x+14
Solve for x and name the steps taken.
Answer:
Simplifying
5x = 3x + 14
Reorder the terms:
5x = 14 + 3x
Solving
5x = 14 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
5x + -3x = 14 + 3x + -3x
Combine like terms: 5x + -3x = 2x
2x = 14 + 3x + -3x
Combine like terms: 3x + -3x = 0
2x = 14 + 0
2x = 14
Divide each side by '2'.
x = 7
Simplifying
x = 7

If t>0 and t2−25=0, what is the value of t?
Answer:
Final answer is [tex]t=5[/tex].
Step-by-step explanation:
Given equation is [tex]t^2-25=0[/tex].
Now we need to solve that equation for t when [tex]t>0[/tex].
[tex]t^2-25=0[/tex]
[tex]t^2-5^2=0[/tex]
[tex](t+5)(t-5)=0[/tex]
or [tex](t+5)=0[/tex], [tex](t-5)=0[/tex]
or [tex]t+5=0[/tex], [tex]t-5=0[/tex]
or [tex]t=-5[/tex], [tex]t=5[/tex]
Given that t>0
so that means t=-5 is not possible.
Hence final answer is [tex]t=5[/tex].
find the given angle to the nearest degree.
Answer:
[tex]\alpha=44\°[/tex]
Step-by-step explanation:
By definition, the tangent of an angle is the quotient between the side opposite the angle and the side adjacent to the angle
In other words:
[tex]tan(\alpha) = \frac{opposite}{adjacent}[/tex]
In this triangle, the length of the side adjacent to the desired angle is 50, and the length of the opposite side is 48
So:
[tex]tan(\alpha) = \frac{48}{50}\\\\tan(\alpha)= 0.96[/tex]
Finally
[tex]\alpha =arctan(0.96)\\\\\alpha=44\°[/tex]
Answer:
Final answer is [tex]?=44[/tex] degree.
Step-by-step explanation:
Using given information in the picture, we need to find the missing value of angle "?"
Apply formula of tangent function which is :
[tex]\tan\left(\theta\right)=\frac{opposite}{adjacent}[/tex]
[tex]\tan\left(?^o\right)=\frac{48}{50}[/tex]
[tex]\tan\left(?^o\right)=0.96[/tex]
[tex]?=\tan^{-1}\left(0.96\right)[/tex] degree
[tex]?=43.830860672092581097187030418859[/tex] degree
Hence final answer is [tex]?=44[/tex] degree.
which value makes this equation true -4x = 20
Answer:
x= -5 makes the given equation -4x = 20 true
Step-by-step explanation:
We have been given the equation;
-4x = 20
we are to determine the value of x that will make the equation true. We simply make x the subject of the formula;
divide both sides of the equation by -4;
(-4x)/(-4) = 20/(-4)
x = -5
Therefore, x= -5 makes the given equation -4x = 20 true
Answer:
[tex]x=-5[/tex]
Step-by-step explanation:
The given linear equation is:
-4x = 20
To find the value of x that makes the equation true, we need to solve for x.
We divide both sides by -4 to obtain:
[tex]\frac{-4x}{-4}=\frac{20}{-4}[/tex]
This is the sane as:
[tex]\frac{-4x}{-4}=\frac{-5\times-4}{-4}[/tex]
We cancel out the common factors to get:
[tex]x=-5[/tex]
What is the inverse equation of the function, y=5x-4
Answer:
y^-1 = (x + 4)/5
Step-by-step explanation:
To find the inverse equation of the function y=5x - 4, first we need to switch the x and y:
→ y = 5x - 4
→ x = 5y - 4
Now, solving for 'y':
→ x = 5y - 4
→ x + 4 = 5y
→ y = (x + 4)/5
therefore, the inverse equation is: y^-1 = (x + 4)/5
Sally's $8,800 savings is in two accounts. One account earns 2% annual interest and the other earns 6%. Her total interest for the year is $440. How much does she have in each account?
Answer:
In the 2% account, Sally has $2200 and in the 6% account, Sally has $6600.
Step-by-step explanation:
Suppose the amount invested at 2% is $X and the amount invested at 6% is $Y (assuming that the college student invested all his/her income on the two schemes). Therefore:
X + Y = 8800 (The sum of investments is basically the total income).
0.02X + 0.06Y = 440 (The sum of the interest received from the invested amounts is actually the total return).
Now solving these 2 simultaneous equations:
x + y = 8800 (Equation 1)
2x + 6y = 44000 (Equation 2)
From (Equation 1):
x = 8800 - y (Equation 3)
Put (Equation 3) in (Equation 2):
2(8800 - y) + 6y = 44000.
17600 - 2y + 6y = 44000.
4y = 26400
y = 6600.
To find x, substitute y = 6600 in equation 3. This gives:
x = 8800 - y.
x = 8800 - 6600.
x = 2200.
So in the 2% account, Sally has $2200 and in the 6% account, Sally has $6600!!!

a rectangular prism with dimensions 3 by 4 by 8 has the same volume as a different rectangular prism with dimensions 4 by 4 by what?
let's recall that the volume of a rectangular prism is simply the product of its 3 dimensions.
so the volume for the first one is simply 3*4*8 = 96.
now, let's do some quick prime factoring of that 96
96 = 2*2*2*2*2*3
since we know the factors of 96, and we can rearrange them in any way we wish and will always have a product of 96, well, le'ts do some rearranging for the second prism.
the second prism has 4 and 4, namely 2*2 and 2*2, what's leftover? 2*3.
so the second prism must be (2*2) * (2*2) * (2*3), namely a 4x4x6.
What is the complete factorization of the polynomial below x^3+x^2+9x+9
The complete factorization of the polynomial [tex]x^3 + x^2 + 9x + 9[/tex] is [tex]x + 1)(x^2 + 9)[/tex] using real coefficients, and [tex](x + 1)(x + 3i)(x - 3i)[/tex] using complex coefficients.
The complete factorization of the polynomial [tex]x^3 + x^2 + 9x + 9[/tex] can be found by grouping and factoring terms with common factors.
To proceed, let's group the terms as follows: [tex](x^3 + x^2) + (9x + 9).[/tex]
Factoring out the common factors in each group gives us [tex]x^2(x + 1) + 9(x + 1).[/tex]
Now, we notice that (x + 1) is a common factor in both terms, so we can factor it out to get our complete factorization: [tex](x + 1)(x^2 + 9).[/tex]
As [tex]x^2 + 9[/tex] can't be factored further using real coefficients, this is the fullest factorization in the realm of real numbers.
However, if complex numbers are considered, [tex]x^2 + 9[/tex] can be expressed as [tex](x + 3i)(x - 3i)[/tex], where i is the imaginary unit.
So, the complete factorization using complex coefficients is [tex](x + 3i)(x - 3i)[/tex]
