Answer:
[tex]x^3[/tex]-15[tex]x^{2}[/tex]+25x-125
Step-by-step explanation:
This is a quadratic equation, so we need to open the equation first. There are three (x-5), and then we multiply them together, and then combine like terms to get the answer.
(x-5)(x-5)(x-5)=
[x(x-5)-5(x-5)](x-5)=
([tex]x^{2}[/tex]-5x-5x+25)(x-5)=
([tex]x^{2}[/tex]-10x+25)(x-5)=
x([tex]x^{2}[/tex]-10x+25)-5([tex]x^{2}[/tex]-10x+25)
[tex]x^3[/tex]-[tex]10x^2[/tex]+25x-[tex]5x^2[/tex]-125=

Combine like terms. Like terms have the same variables and the same exponents.
3x^2 and -2x^2 are like terms and can be combined.
-x and 5x are like terms and can be combined.

Alessandra is raising turtles and must keep the air temperature in their enclosure at 32. C , with a relative error less than 3%. Write an absolute value inequality for the actual temperature
The absolute value inequality for the temperature T is:
|T - 32°C| < 0.96°C
How to write the absolute value inequality?
The general way of writing these inequalities is:
|variable - average value| < accepted error.
Here the variable is the temperature so we can use T for it.
The average is 32°C, and the accepted error is less than 3%, so it is:
0.03*32°C = 0.96°
Then the absolute value inequality will be:
|T - 32°C| < 0.96°C
Where it means that the temperature will be at less of 0.96°C of the 32°C.

What is the value of x?
6.75+3/8×=13 1/4
Answer:
x = 17.3333
Step-by-step explanation:
Solve for x:
(3 x)/8 + 6.75 = 13 + 1/4
Hint: | Put the fractions in (3 x)/8 + 6.75 over a common denominator.
Put each term in (3 x)/8 + 6.75 over the common denominator 8: (3 x)/8 + 6.75 = (3 x)/8 + 54/8:
(3 x)/8 + 54/8 = 13 + 1/4
Hint: | Combine (3 x)/8 + 54/8 into a single fraction.
(3 x)/8 + 54/8 = (3 x + 54)/8:
(3 x + 54)/8 = 13 + 1/4
Hint: | Put the fractions in 13 + 1/4 over a common denominator.
Put 13 + 1/4 over the common denominator 4. 13 + 1/4 = (4×13)/4 + 1/4:
(3 x + 54)/8 = (4×13)/4 + 1/4
Hint: | Multiply 4 and 13 together.
4×13 = 52:
(3 x + 54)/8 = 52/4 + 1/4
Hint: | Add the fractions over a common denominator to a single fraction.
52/4 + 1/4 = (52 + 1)/4:
(3 x + 54)/8 = (52 + 1)/4
Hint: | Evaluate 52 + 1.
52 + 1 = 53:
(3 x + 54)/8 = 53/4
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (3 x + 54)/8 = 53/4 by 8:
(3 x + 54)/(8 1/8) = 1/4×1/(1/8) 53
Hint: | Any nonzero number divided by itself is one.
1/8×1/(1/8) = 1:
3 x + 54 = 1/4×1/(1/8) 53
Hint: | Write 1/4×1/(1/8) as a single fraction.
Multiply the numerator of 1/4×1/(1/8) by the reciprocal of the denominator. 1/4×1/(1/8) = 1/4×8:
3 x + 54 = 1/4×8×53
Hint: | Express 1/4×8×53 as a single fraction.
1/4×8×53 = (8×53)/4:
3 x + 54 = (8×53)/4
Hint: | In (8×53)/4, divide 8 in the numerator by 4 in the denominator.
8/4 = (4×2)/4 = 2:
3 x + 54 = 2×53
Hint: | Multiply 2 and 53 together.
2×53 = 106:
3 x + 54 = 106
Hint: | Isolate terms with x to the left hand side.
Subtract 54 from both sides:
3 x + (54 - 54) = 106 - 54
Hint: | Look for the difference of two identical terms.
54 - 54 = 0:
3 x = 106 - 54
Hint: | Evaluate 106 - 54.
106 - 54 = 52:
3 x = 52
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 3 x = 52 by 3:
(3 x)/3 = 52/3
Hint: | Any nonzero number divided by itself is one.
3/3 = 1:
x = 52/3
Hint: | Express 52/3 in decimal form.
52/3 = 17.3333:
Answer: x = 17.3333

The measure of the complement of the supplement of angle A is 28°. The measure in degrees of angle A is
You can put this solution on YOUR website!
Define your variables,
Let X be your Angle
Then 180 - X is your Supplement
and 90 - X is your complement
Now you need to put these into an equation, this particular word probled does not have the equal sign "IS" however, the word measure0-xs, is the same, so that is where your = sign will go.
Your Equation should be...
180-x=2*(90-x)+28
Distribute
180-x=180-2x=28
Subtract 180 From Both Sides and add 2X to Both Sides
X+=+28
Your angle is 28, the Supplement is 152 and your Complement is 62

for the past five baseball seasons miguel had 122 45 109 124 and 115 hits what is his median number of hits for the past five seasons
Answer:
His median hit = 115
Step-by-step explanation:
Given:
122 45 109 124 and 115 hits
To find his median hit, you will either arrange the hits in ascending order or descending order
In ascending order (lowest to highest value)
45, 109, 115, 122, 124
In descending order (highest to lowest value)
124, 122, 115, 109, 45
It can be observed that thehe hits are 5
The median is the middle value
From either the ascending or descending order arrangement, 115 is the middle hit.
Therefore, his median hit = 115

Explanation:
This is a piecewise function. It's composed of 3 pieces of other functions. A piecewise function is a function that changes its identity based on what the input is.
We have three different situations here
If t = 17, then h(t) = sqrt(17t) based on what the first row saysIf t = 19, then h(t) = -34/t which is the second row of the piecewise function.If t does not equal either 17 or 19 (ie t is anything but those values), then h(t) = 23-tThe notation h(17) means we want to evaluate h(t) when t = 17. So we'll use the first case mentioned above. Plug t = 17 into h(t) = sqrt(17t) to get...
h(t) = sqrt(17t)
h(17) = sqrt(17*17)
h(17) = sqrt(17^2)
h(17) = 17
In the last step, I used the rule that sqrt(x^2) = x when x is nonnegative.

Hope This Helps :)
The domain of the function will be 0 < x ≤ 5. The correct option is A.
What is a domain?In mathematics, a domain typically refers to a set of values for which a particular function or equation is defined. For example, the domain of the function f(x) = 1/x is all real numbers except for x = 0 since the function is undefined at that point.
The Domain is the first coordinate which is x. The Range is the second coordinate which is y.
The domain of the given graph in the image will be calculated as,
0 < x ≤ 5
Therefore, the correct option is A.

A company is looking to hire a lawyer. One law firm states that their legal fees can be determined using the expression 350x + 22,000, where x is the number of hours of legal assistance. A second law firm states that their legal fees can be determined using the expression 410x+16,000. The company president wants to know when the legal fees would cost the same for each law firm. What number of hours of legal assistance makes the equation 350x+22,000 = 410x+16,000 true?
Answer:
100 hours
Step-by-step explanation:
The number of hours of legal assistance that makes the expressions 350x+22,000 = 410x+16,000 true is 100 hours.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
We have,
Two expressions that denoted the legal fees for x hours:
350x + 22,000 ____(1)
410x+16,000 _____(2)
Where x = number of hours
The number of hours where both the legal fees are equal:
350x + 22,000 = 410x + 16,000
Subtract 350x on both sides.
22,000 = 410x -350x+ 16,000
22,000 = 60x + 16,000
Subtract 16,000 on both sides.
22,000 - 16,000 = 60x
6,000 = 60x
Divide both sides by 60.
x = 100
Thus,
The number of hours of legal assistance that makes the expressions 350x+22,000 = 410x+16,000 true is 100 hours.

(25 POINTS!!!!) a rectangular garden measures 5 feet by 4 feet. The length and width are both increased by the same amount and the new area is 56 square feet. What are the new dimensions of the garden?
The new dimensions of the garden are 8 feet and 7 feet.
What is rectangle?A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.
Given that,
The length of rectangular garden = 5 feet,
And the width of rectangular garden = 4 feet.
The area of rectangular garden = 5 x 4 = 10 square feet.
Let the length and width are increased by x feet, to make the new area 56 square feet.
The new length = 5 + x,
and new width = 4 + x.
The area = 56
(5 + x) × (4 + x) = 56
Substitute, x= 3 which satisfies the equation,
So, the new length of garden = 5 + 3 = 8 feet,
And the new width of garden = 4 + 3 = 7 feet.
