Answer: X intercept: (-4,0) Y Intercept: (0,-3)

Step-by-step explanation: i dont know if thats how it was suppose to be done or not but that is just the intercepts for it.

Answer:

x^2-2x-13

Step-by-step explanation:

f(x) = 2x-5

g(x) = x^2 -4x-8

f(x) +g(x) = 2x-5 + x^2 -4x-8

Combine like terms

= x^2+2x-4x-5-8

=x^2-2x-13

Let V be the volume of the solid obtained by rotating about the y-axis the region bounded y = 4x and y = x2/4 . Find V by slicin

aliya0001 [1]

Answer:

Step-by-step explanation:

Consider the graphs of the $y = 4x$ and $y = \frac{x^{2} }{4}$ .

By equating the expressions, the intersection points of the graphs can be found and in this way delimit the area that will rotate around the Y axis.

$4x = \frac{x^{2} }{4} \\ x^{2} = 16x \\ x^{2} - 16x = 0 \\ x(x-16) = 0$ then $x=0$ o $x=16$ . Therefore the integration limits are:

$y = 4(0) = 0$ and $y = 4(16) = 64$

The inverse functions are given by:

$x = 2 \sqrt{y}$ and $x = \frac{y}{4}$ . Then

The volume of the solid of revolution is given by:

$\int\limits^{64}_ {0} \, [2\sqrt{y} - \frac{y}{4}]^{2} dy = \int\limits^{64}_ {0} \, [4y - y^{3/2} + \frac{y^{2}}{16} ]\ dy = [2y^{2} - \frac{2}{5}y^{5/2} + \frac{y^{3}}{48} ]\limits^{64}_ {0} = 546.133 u^{2}$

Explain how you know that the some of 12.6, 3.1, and 5.4cis greater than 20

ddd [48]

You can add the numbers together so:

12.6
3.1
+ 5.4
 21.1

Since the sum of the numbers is 21.1, it is greater than 20

A 2/3=8/2. B. 4/9=8/9 c 3/4>9/10 d 2/4>2/3 which comparison is true

vladimir2022 [97]

The given comparisons are not true in all of the options provided.

Step-by-step explanation:

The given comparisons are in the form of fractions.

Check each of the given options one by one based on the relation given for the comparison.

Option a) is 2/3 = 8/2. Here, you have to check that the given fractions are equal or not. If both the values are equal, then the comparison is true. If they are not equal, then the comparison is false.

By dividing 2 by 3, we get a value of 0.666

By dividing 8 by 2, we get a value of 4.

Therefore, 0.666 ≠ 4. The comparison is false.

Option b) is 4/9 = 8/9. Here, you have to check that the given fractions are equal or not.

Look into the given comparison, the fractions have same denominator of 9.

In such cases, if the denominator is same and the numerator value is different, then they are not equal.

Therefore, 4/9 ≠ 8/9. The comparison is false.

Option c) is 3/4 > 9/10. Here, you have to check whether 3/4 is greater than 9/10.

By dividing 3 by 4, we get a value of 0.75

By dividing 9 by 10, we get a value of 0.9

Therefore, 0.75 is not greater than 0.9. The comparison is false.

Option d) is 2/4 > 2/3. Here, you have to check whether 2/4 is greater than 2/3.

By dividing 2 by 4, we get a value of 0.5

By dividing 2 by 3, we get a value of 0.666

Therefore, 0.5 is not greater than 0.666. The comparison is false.
