John says all of the factors for the number 28 are
1, 2, 3, 4, 7, 14, 28
But he is incorrect! Which number is not a factor of 28?

Answer:

a. 3 : 2

b. 2 : 15

c. 3 : 2

Step-by-step explanation:

Red fish = 3

Yellow fish = 6

White fish = 4

Black fish = 2

Total number of fishes = 15

a) Ratio of the Number of yellow fish to the number of white fish.

Yellow fish : White fish

6 : 4

= 6 /4

= 3/2

= 3 : 2

Ratio of the Number of yellow fish to the number of white fish = 3 : 2

b) Ratio of the Number of black fish to the total number of fish

Black fish : Total fish

2 : 15

= 2 / 15

= 2 : 15

Ratio of the Number of black fish to the total number of fish = 2 : 15

c) Ratio of the Number of red fish to the number of black fish

Red fish : black fish

= 3 : 2

= 3/2

= 3 : 2

Ratio of the Number of red fish to the number of black fish = 3 : 2

Step-by-step explanation:

The volume of the solid formed by rotating the region about the y-axis is 6π/7 cubic units.

To find the volume of the solid formed by rotating the region bounded by the curves y = x³/4, x = 0, y = 1 in the first quadrant about the y-axis, we can use the method of cylindrical shells.

The formula for the volume using cylindrical shells is:

[tex]\mathrm V = \int\limits^a_b {2\pi \mathrm x \times \mathrm f(x)} \, dx[/tex]

Where:

a and b are the limits of integration (in this case, a = 0 and b = 1 since we are rotating in the first quadrant).

f(x) is the height of the shell at the given x-value.

2πx is the circumference of the shell at the given x-value.

In this case, we need to express y = x³/4 in terms of x to find the function f(x).

Given: y = x³/4

To find the function in terms of x, solve for x:

[tex]x = (4y)^{(1/3)[/tex]

Now, the function f(x) becomes:

[tex]\mathrm f(x) = (4x)^{(1/3)[/tex]

Now, let's calculate the volume using the cylindrical shell method:

[tex]\mathrm V = \int\limits^1_0 {2\pi \mathrm x \times \mathrm 4x^{1/3}} \, dx[/tex]

[tex]\mathrm V = 2\pi \int\limits^1_0 { x^{4/3}} \, dx[/tex]

To integrate, add 1 to the exponent and divide by the new exponent:

[tex]\mathrm V = 2\pi \times (3/7) \times x^{(7/3)} |^0_1[/tex]

Now, evaluate the expression at the limits of integration:

[tex]\mathrm V = 2\pi \times (3/7) \times (1)^{(7/3)} - 2\pi \times (3/7) \times (0)^{(7/3)[/tex]

[tex]\mathrm V = 2\pi \times (3/7) - 0[/tex]

[tex]\mathrm V = 6\pi/7[/tex]

So, the volume of the solid formed by rotating the region about the y-axis is 6π/7 cubic units.

Step-by-step explanation:

SO THE ANSWER IS 20

Step-by-step explanation:

To find x,equate EF to BC

2y+x=14( from here,it's impossible to calculate the values yet)

Find the value of ‹ACB

180°-(99+45)=36°

Now equate ‹DFE to 36° to find y

8y-5=36

8y=36+5

8y=41

y=5.125

Plug in the value of y to find x

2y+x=14

x=14-2y

x=14-2(5.125)

x=3.75

9514 1404 393

Answer:

  x = -12

  y = 13

  FE = 14

  m∠E = 36°

  AB ≅ DF, BC ≅ FE, AC ≅ DE

  ∠D ≅ ∠A, ∠E ≅ ∠C, ∠F ≅ ∠B

Step-by-step explanation:

The expression involving y is that of an angle measure. In order to find y, we need to know the angle. So, it makes sense to start by identifying corresponding angles and their measures.

The congruence statement ΔABC ≅ ΔDFE means that ...

  ∠A ≅ ∠D . . . 45°

  ∠B ≅ ∠F . . . 99°

  ∠C ≅ ∠E . . . 180° -99° -45° = 36°

It also means ...

  AB ≅ DF . . . 10

  BC ≅ FE . . . 14

  AC ≅ DE . . . unmarked (and unknown*)

__

Using the measure of angle F we can solve for y:

  (8y -5)° = 99°

  8y = 104 . . . . . . divide by ° and add 5

  y = 13 . . . . . . . . divide by 8

Using the length of side FE, we can solve for x:

  2y +x = 14

  2·13 +x = 14 . . . . substitute for y

  x = 14 -26 . . . . . .subtract 26

  x = -12

_____

* The length of the unmarked side is unknown because its measure will depend on how you compute it. The given angles and side lengths are inconsistent, so the figure shown cannot exist. If angle measures are taken as accurate, the side measures are not, and vice versa.

Answer: As x -> ♾, h(x) -> -♾, and as x -> -♾,h(x) -> -♾

Step-by-step explanation:

The end behavior is x ----> ∞ then h(x) ----> -∞, and when x ----> -∞ then h(x) -----> -∞.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

h(x) = -7[tex]x^6[/tex] + 3 [tex]x^4[/tex]– 5x².

If we plot the Equation on the Graph we can see a parabolic Curve.

This Curve tells as x tends to ∞ the value of h(x) tends to -∞.

and, when x tends to -∞ the value of h(x) tends to -∞.

Hence, the end behavior is x ----> ∞ then h(x) ----> -∞.

and, when x ----> -∞ then h(x) -----> -∞.

Answer: No, the triangles do not lie on the same graphed line

=========================================================

Explanation:

Your teacher is asking if the hypotenuse segments are parallel, that way one line can slide over to the other to be directly on top of it.

Recall that parallel lines have the same slope, and slope is rise over run.

rise = change in vertical distance = change in y

run = change in horizontal distance = change in x

Let's find the slope of the hypotenuse of the triangle on the left

slope = rise/run = 15/2 = 7.5

Let's do the same for the other triangle as well

slope = rise/run = 51/6 = 8.5

The slopes are different, so we don't have a perfect match. The hypotenuse segments do not lie on the same line.
