Answer:

Gene is incorrect.

Step-by-step explanation:

Let x represent the number.

We have been given that Gene stated that finding 25% of a number is the same as dividing the number by 1/4. We are asked to determine whether Gene is correct or not.

We know that percent means a quantity out of 100. We can represent 25% of x as:

We can further simply it as:

We can see that finding 25% of a number is equal to finding one-fourth of a number.

When we divide a number by 1/4, we will get:

Dividing a number by 1/4 will be 4 times the number, therefore, Gene is not correct.

According to the question ,In the given range 0.8 ≤ x ≤ 1.2, the function f(x) can be approximated by the Taylor polynomial P2(x) = -2 + x.

To approximate f(x) using a Taylor polynomial with degree n at a=1, we need to find the values of the first n derivatives of f(x) at x=1.

f(x) = x-4
f'(x) = 1
f''(x) = 0
f'''(x) = 0
...

Since all the higher-order derivatives are zero, we only need to consider the first two derivatives.

f(1) = 1-4 = -3

f'(1) = 1

Using the Taylor series formula, we can write the Taylor polynomial of degree n at a=1 as:

Pn(x) = f(a) + f'(a)(x-a) + f''(a)(x-a)^2/2 + ... + f^(n)(a)(x-a)^n/n!

Substituting the values we obtained, we have:

P2(x) = -3 + 1(x-1) + 0(x-1)^2/2

P2(x) = -2 + x

So the Taylor polynomial of degree 2 at a=1 is P2(x) = -2 + x.

Now we can use this polynomial to approximate f(x) in the given range.

For x=0.8,

P2(0.8) = -2 + 0.8 = -1.2

For x=1.2,

P2(1.2) = -2 + 1.2 = -0.8

Therefore, in the given range 0.8 ≤ x ≤ 1.2, the function f(x) can be approximated by the Taylor polynomial P2(x) = -2 + x.

The measure of angle x in the right triangle is approximately 14.6 degrees.

The figure in the image is that of two right angles.

First, we determine the hypotenuse of the left-right angle.

Angle θ = 30 degrees

Adjacent to angle θ = 10 cm

Hypotenuse = ?

Using the trigonometric ratio.

cosine = adjacent / hypotenuse

cos( 30 ) = 10 / hypotenuse

hypotenuse = 10 / cos( 30 )

hypotenuse = \(\frac{20\sqrt{3} }{3}\)

Using the hypotenuse to solve for x in the adjoining right triangle:

Angle x =?

Adjacent to angle x = \(\frac{20\sqrt{3} }{3}\)

Opposite to angle x = 3

Using the trigonometric ratio.

tan( x ) = opposite / adjacent

tan( x ) = 3 / \(\frac{20\sqrt{3} }{3}\)

tan (x ) = \(\frac{3\sqrt{3} }{20}\)

Take the tan inverse

x = tan⁻¹(  \(\frac{3\sqrt{3} }{20}\) )

x = 14.6 degrees

Therefore, angle x measures 14.6 degrees.

Number of Inches there are in 7 yards is 252inches

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

Given;

3feet= 1yard

12inch= 1foot

So,

1foot= 12inch

3feet= 12 x 3inch

        = 36inch...(1)

1yard= 3feet

7yard= 7 x 3 x 1foot

According to this equation, a meerkat's expected lifespan in captivity is (A) 11.6 years.

So,l the predicted lifespan of the meerkat in captivity, according to the equation is:

The equation we have is: In(L) = 2.468 + 0.2 In(M)

We know that: M = 0.9

Now, put M = 0.9 in equation as follows: In(L) = 2.468 + 0.2 In(0.9)

Taking the natural algorithm of 0.9 as follows:

In(L) = 2.468 + 0.2 × -0.1054

In(L) = 2.468 - 0.02108

In(L) = 2.22692

Now, taking exponents as follows:

L = e²°⁴⁴⁶⁹²

L = 11.553

Rounding off: 11.6

Answer:

(x + 2)^2 + (y - 6.5)^2 = 25.25

Step-by-step explanation:

We can the equation of the circle in standard form, whose general equation is:

\((x-h)^2+(y-k)^2=r^2\), where

Step 1:  We know that the diameter is simply 2 * the radius.  Thus, we can find the radius by first finding the length of the diameter.  To do this, we'll need the distance formula, which is:

\(d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }\), where

We can allow (-7, 7) to be our (x1, y1) and (3, 6) to be our (x2, y2) point and plug these into the formula to find d, the distance between the points and the length of the diameter:

\(d=\sqrt{(3-(-7))^2+(6-7)^2} \\d=\sqrt{(3+7)^2+(-1)^2}\\ d=\sqrt{(10)^2+1}\\ d=\sqrt{100+1}\\ d=\sqrt{101}\)

Now we can multiply our diameter by 1/2 to find the length of the radius:

r = 1/2√101

Step 2:  We know that the center lies at the middle of the circle and therefore represents the midpoint of the diameter.  The midpoint formula is

\(m=(\frac{x_{1}+x_{2} }{2}),(\frac{y_{1}+y_{2} }{2})\), where

We can allow (-7, 7) to be our (x1, y1) point and (3, 6) to be our (x2, y2) point:

\(m=(\frac{-7+3}{2}),(\frac{7+6}{2})\\ m=(\frac{-4}{2}),(\frac{13}{2})\\ m=(-2,6.5)\)

Thus, the coordinate for the center are (-2, 6.5).

Step 3:  Now, we can create the equation of the circle and simplify:

(x - (-2)^2 + (y - 6.5)^2 = (1/2√101)^2

(x + 2)^2 + (y - 6.5)^2 = 25.25

Answer:

see explanation

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 6 ( sides of a hexagon ) , then

sum = 180° × 4 = 720°

(a)

let x be the sixth interior angle , then

90° + 100° + 110° + 120° + 130° + x = 720 , that is

550° + x = 720° ( subtract 550° from both sides )

x = 170°

(b)

the sum of the exterior angles of a polygon is 360°

exterior angle + interior angle = 180°

exterior angle = 180° - interior angle

Then

180° - 90° = 90°

180° - 100° = 80°

180° - 110° = 70°

180° - 120° = 60°

180° - 130° = 50°

180° - 170° = 10°

sum = 90° + 80° + 70° + 60° + 50° + 10° = 360° ← correct total

Answer:

let the two numbers = x and y

according to the statement : x-y=4

x+y=22

by elimination method: 2x=26

x=13

so... y = 13-4=9

Answer:

The two numbers (x and y) are 13 and 9 respectively. 13 minus 9 is 4 and 13 plus 9 is 22.

Step-by-step explanation:

Let the two numbers be x and y.

The difference between x and y (x - y) = 4. (eqn 1)

Their sum (x + y) = 22. (eqn 2)

From eqn 1, we can get that x = 4 + y

Substituting x as (4 + y) in eqn 2 gives the following:

(4+y) + y = 22

4 + 2y = 22

and 2y = 22 - 4

2y = 18

dividing both sides by 2 gives y = 9.

Substituting y as 9 in eqn 1 gives

x - 9 = 4

x = 4 + 9

x = 13

To determine the solution to the given differential equation with the initial condition, we need to solve the differential equation and substitute the initial condition into the solution.

Start by solving the differential equation: Rewrite the equation as dy/dt = -2 - y.

Separate variables: Move all terms involving y to one side and all terms involving t to the other side. This gives dy/(y+2) = -dt.

Integrate both sides: Integrate the left side with respect to y and the right side with respect to t. This yields ln|y+2| = -t + C, where C is the constant of integration.

Solve for y: Take the exponential of both sides to eliminate the natural logarithm. This gives |y+2| = e^(-t+C).

Apply the initial condition: Substitute y = -3 and t = 0 into the equation. This gives |-3+2| = e^(0+C), which simplifies to 1 = e^C.

Determine the constant of integration: Since e^C is always positive, we can remove the absolute value sign. Therefore, y+2 = e^(-t).

Solve for y: Subtract 2 from both sides to obtain the solution in the form y = -e^(-t) - 2.

Compare the solution with the given options: The solution that matches the differential equation and the initial condition is y = -e^(-t) - 2. Therefore, the correct answer is option B.

For option (a), if side a on the scale drawing is 63 inches long, then the real object's side a would be 63 x 3 = 189 inches long. Similarly, if side b on the scale drawing is 54 inches long, then the real object's side b would be 54 x 3 = 162 inches long.

For option (b), if side a on the scale drawing is 24 inches long, then the real object's side a would be 24 x 3 = 72 inches long. Similarly, if side b on the scale drawing is 21 inches long, then the real object's side b would be 21 x 3 = 63 inches long.

For option (c), if side a on the scale drawing is 7 inches long, then the real object's side a would be 7 x 3 = 21 inches long. Similarly, if side b on the scale drawing is 6 inches long, then the real object's side b would be 6 x 3 = 18 inches long.

For option (d), if side a on the scale drawing is 18 inches long, then the real object's side a would be 18 x 3 = 54 inches long. Similarly, if side b on the scale drawing is 15 inches long, then the real object's side b would be 15 x 3 = 45 inches long.
