Answer:
-4x^3 +12x^2 for 0 < x < 3
Step-by-step explanation:
The power rule is appropriate:
(d/dx)x^n = n·x^(n-1)
This is applied to each of the terms.
F'(x) = -(4·x^3) +4(3x^2) +0
F'(x) = -4x^3 +12x^2 . . . . for 0 < x < 3
__
The derivative is not defined at the endpoints of the interval, so F'(x) is only defined on (0, 3), not [0, 3].
Write this ratio as a fraction in simplest form without any units. 21 feet to 10 yards
The ratio 21 feet to 10 yards can be simplified and written as a fraction. By converting feet to yards, we get the ratio 7 yards to 10 yards or the fraction 7/10, which is already in its simplest form.
Explanation:In order to write the ratio 21 feet to 10 yards as a fraction in simplest form, we need to first convert feet into yards. One yard is equivalent to three feet. Therefore, we can transform 21 feet to 7 yards. The ratio thus translates to 7 yards to 10 yards. Writing this ratio as a fraction, we get 7/10. Since 7 and 10 have no common factors other than 1, the fraction 7/10 is already in its simplest form.

Does 2.1,7.2,7.5 make a right triangle
Answer: yes it does
Step-by-step explanation:
When you graph it on a graph piece of paper it is a right triangle
Answer:
2.1 , 7.2 , 7.5 does NOT make a right triangle
Step-by-step explanation:
Finding if the values make a right angled trianglethe formula for finding if its an acute , obtuse , right-angled triangle
acute [tex]c^{2} < a^{2} + b^{2}[/tex]
obtuse [tex]c^{2} > a^{2} + b^{2} \\[/tex]
right angled [tex]c^{2} = a^{2} + b^{2}[/tex]
c is the hypotenuse
a and b are the adjacent and the opposite
the values given are 2.1 , 7.2 , 7.5
hence :
c would be 2.1
a would be 7.2
b would be 7.5
now we can put this into the right angled triangle formula to see if its correct.
[tex]c^{2} = a^{2} + b^{2}[/tex]
lets first see the value of [tex]a^{2} + b^{2}[/tex]
= 7.2^2 + 7.5^2
[tex]a^{2} + b^{2}[/tex] = 108.09
to check if its a right angled triangle we check if the value of c^2 gives 108.09.
find the value of [tex]c^{2}[/tex]
= 2.1 ^2
[tex]c^{2}[/tex] =4.41
hence 4.41 is NOT equal to 108.09
hence its not a right angled triangle but rather an acute angle.
2.1 , 7.2 , 7.5 does NOT make a right triangle
1 What is the slope of the graph of y = 12x – 19?
Answer:-228
Step-by-step explanation:
An angle measures 65.6° less than the measure of its complementary angle. What is the
measure of each angle? This is IXL w17 7th grade. Thanks!
Answer:
The 2 angles are 12.2 and 77.8 degrees.
Step-by-step explanation:
Let the measure of one angle be x degrees, then it's complementary angle = 90-x degrees.
So we have the equation:
x = 90 - x - 65.6
2x = 90 - 65.6 = 24.4
x = 12.2 degrees.
Its complement = 90 - 12.2 = 77.8 degrees.

A wire is first bent into the shape of a square. Each side of the square is 6cm long. Then the wire is unbent and reshaped into a rectangle. If the length of the rectangle is 9cm, what is its width?
Hi there!
Assuming a perfect square: we know there are 4 sides in a square, and all of them have equal length. This means that every side of the square is 6 cm, and with 4 sides, that would make an overall length / perimeter of 6 + 6 + 6 + 6, or 6*4, which would equal 24 cm. This means that our wire must be 24 cm long.
Now, for the rectangle. We know with rectangles that they also have 4 sides, and in pairs of 2 in terms of length (2 of the sides have the same length, and the other two have the same length). This means we know there are 2 sides that are 9 cm, which would mean 18 cm in total. This is the total amount of wire taken up by the length, but we are looking for the width. Thus, we can see how much wire is leftover not taken up by the length by subtracting 18 from 24:
24-18=6
Now, we see that the two sides that make up the width are 6 cm long. As those two sides are equal length, we can divide 6 cm into two equal parts to see the width.
6/2 = 3 cm.
Thus, the width of the rectangle is 3 cm.
Hope this helps!
The wire, when bent into a square, has a total length of 24cm. When reshaped into a rectangle with a length of 9cm, the width must be 3cm to maintain the same total length.
Explanation:The subject of this problem is geometry and algebra. We know that a wire is bent into the shape of a square with each side being 6cm. The total length of the wire is the perimeter of the square, which can be calculated as 4 * side length, so the total length of the wire is 4*6 = 24cm.
Then the wire is reshaped into a rectangle where the length is given as 9cm. Since the total length of the wire has not changed, the perimeter of the rectangle is also 24cm. The perimeter of a rectangle can be calculated as 2*(length + width). If we set this equal to 24, we get 2 * (9 + width) = 24. Solving for width, we find that the width is 3cm.

If f(x) = 4x^0 + (4x)^-1, what is the value of f(4)
Answer:
[tex]\frac{65}{16}[/tex] or 4.0625
Step-by-step explanation:
To solve this problem, all we have to do is input the value x = 4 into the equation and solve.
f(4) = 4(4)^0 + (4x)^-1
f(4) = 4(1) + 1/4(4)
f(4) = 4 + 1/16
f(4) = [tex]\frac{64}{16}[/tex] + [tex]\frac{1}{16}[/tex]
f(4) = [tex]\frac{65}{16}[/tex]
f(4) = 4.0625
A farmer owns a rectangular-shaped farm. She knows that the length is 2 km longer than the width and the perimeter is 16 km. Find 'x', the width of her
farm.
Answer:
x = 3
Step-by-step explanation:
x + x + x + 2 + x + 2 = 16 (combine like terms)
4x + 4 = 16 (subtract 4 from each side)
4x = 12 (divide each side by 4)
x = 3
Let's check:
(3 + 2) × 2 = 10
3 × 2 = 6
10 + 6 = 16
It works.
Answer:
length= 5 km
Width=3 km
Step-by-step explanation:
Length=Width+2
L=W+2
Perimeter = 16 km
Perimeter of the rectangular field = 2(Length+Width)
[tex]16 = 2*(Width+2+Width)\\\16=2(W+2+W)\\\\16=2(2W+2)\\\\16/2=2W+2\\\\8=2W+2\\\\2W=8-2\\\\2W=6\\\\W=6/2\\\\W=3 km[/tex]

You start at (-5, 5). You move down 6 units and up 5 units. Where do you end?
Answer:
(-5, 4)
Step-by-step explanation:
if you are moving up and down only the y part of the coordinate will change so 5 going 6 down would put you at -1 then going 5 up would put you at 4
Final answer:
Starting at (-5, 5), moving down 6 units and then up 5 units results in a final position of (-5, 4).
Explanation:
If you start at the point (-5, 5) and then move down 6 units, your vertical position decreases by 6. That means you subtract 6 from 5, the y-coordinate, resulting in -1. However, if you then move up 5 units, you're adding 5 back to your y-coordinate. So, you take -1 and add 5, which results in 4. Your final position then is still at the same x-coordinate, -5, but with a new y-coordinate of 4. Therefore, the point you end up at is (-5, 4).
There are 40 students playing dodge ball in a high school gym that is 100 feet long by 60 feet wide. There are 12,000 balls available in the gym to throw. What is the population density of the balls in the gym (balls per square foot)?
Answer:
2 balls/ft²
Step-by-step explanation:
The area of the gym is:
A = (100 ft) (60 ft)
A = 6,000 ft²
The population density is:
D = 12,000 balls / 6,000 ft²
D = 2 balls/ft²
Final answer:
To calculate the population density of balls in a gym, divide the total number of balls by the gym's area in square feet. In this case, with 12,000 balls and a gym of 6,000 square feet, the population density is 2 balls per square foot.
Explanation:
The question involves calculating the population density of balls in a gym. First, we need to find the area of the gym to understand the space these balls will occupy. The gym is 100 feet long and 60 feet wide, thus its area is 100 * 60 = 6,000 square feet.
Next, we're told there are 12,000 balls available in the gym. To find the population density of the balls, the number of balls is divided by the area of the gym. So, the population density is 12,000 balls divided by 6,000 square feet, which equals 2 balls per square foot.
Find the volume of a rectangular prism with a length of 13.2 in, a width of 13.8 in and
a height of 15.9 in, to the nearest tenth of a cubic inch.
Final answer:
To find the volume of a rectangular prism, multiply its length, width, and height. For this specific prism, the volume is 2936.76 cubic inches.
Explanation:
Volume is calculated by multiplying the length, width, and height of a rectangular prism:
Volume = length x width x height
Given dimensions: length = 13.2 in, width = 13.8 in, height = 15.9 in.
Substitute the values into the formula: Volume = 13.2 in x 13.8 in x 15.9 in = 2936.76 in³
Therefore, the volume of the rectangular prism is 2936.76 cubic inches.

Find a(33) if the first term in the sequence is 3 and the common difference is -1.
Answer:
Step-by-step explanation:
a(n) = a + (n-1)d
a(33) = 3 + (33-1)*(-1)
= 3 + 32*(-1)
= 3 - 32
= -29
The 33rd term (a33) in an arithmetic sequence starting with 3 and a common difference of -1 is -29. This is achieved by using the formula for finding a term in an arithmetic sequence.
Explanation:The question is asking for the 33rd term in a sequence where the first term is 3 and each following term is derived by subtracting 1 from the previous term, a common process known as an arithmetic sequence. The formula to find any term (an) in an arithmetic sequence is an = a1 + (n - 1)d, where a1 is the first term, d is the common difference, and n is the term number.
So, to find a(33) (the 33rd term), we will fill in the formula as follows: a33 = 3 + (33 - 1)*-1
Which simplifies to: a33 = 3 - 32 = -29
So the 33rd term of the sequence is -29.

Today everything in a store is for sale. THe store offers a 30% discount. The regualar price for a T-shirt is 18$. What is the discount price
Answer:
12.60
Step-by-step explanation:
Start off by the total which is 18. To find the percentage off you will have to make the 30% into a decimal, so simply move it two spaces to the left. Now you have .30. Multiply the decimal, .30, and the full amount, 18. Your equation now should be (.30)*(18). Your answer will be 5.40. 5.40 is what is off of the shirt from the original price, so subtract 5.40 from 18. Your equation now is (18-5.40) which is 12.60.
Is -x + 4y=5 in Standard form of a Linear Function or not?
Answer:
Yes, it is in Standard Form.
Step-by-step explanation:
A linear function in Standard Form would look like:
Ax + By = C
where A, B, and C are real numbers.
A good way to check if a linear function is in Standard Form is by checking if the only the variables and coefficients found on one side of the equation and a real number is found by itself on the other side.
The linear function, -x + 4y = 5, has only the variables and coefficients on the left side of the function, and a real number (5) by itself on the right side.
The linear function, -x + 4y = 5, is in Standard Form.

Cameron wants to buy six video games all costing the same amount he has a $30 coupon and he can spend no more than $100 write an inequality to find the possible cost of each video game
Let's work this problem step by step, using each piece of given information to create the inequality:
Let x represent the cost of each video game that Cameron wants to buy. The price of the 6 games will be 6 multiplied with x, or 6x.Cameron has a $30 coupon, which means that the price of the video games after the coupon will be 30 less than 6x, which is 6x - 30.The last piece of information is that Cameron cannot spend any more than $100. Thus, the equation 6x - 30 must be less than or equal to 100.Putting all this together, we can create the inequality:
