The value of a home in San Diego will increase by 80.6% in 20 years.

Here, we are given that the value of a home in San Diego increases by 3 percent each year.

This means that suppose the value of a home today is V, then its value in a year from now will be V(1 + 0.03)

Thus, its value in 20 years will be-

V(1 + 0.03)(1 + 0.03).......(1 + 0.03)

This, can be written as-

[tex]V(1 + 0.03)^{20}[/tex]

= V × [tex]1.03^{20}[/tex]

= V(1.806)

= 1.806V

Thus, we see that the value of the home increases from V to 1.0806V in 20 years. The percentage change will be-

100(1.806V - V)/V

= 100 × 0.806V/V

= 80.6%

Thus, the value of a home in San Diego will increase by 80.6% in 20 years.

The equation of the line in slope-intercept form is: y = 1/4x + 5.

To write the equation of a line in slope-intercept form, first, find the slope of the line using two points on the graph.

Slope (m) = change in y / change in x = 1/4

m = 1/4.

The y-intercept is the point where the line intercepts the y-axis, which is at 5. Therefore, the y-intercept is b = 5.

To write the equation of the line in slope-intercept form, substitute m = 1/4 and b = 5 into y = mx + b:

The Yield to Maturity (YTM) of the Bond is 8.27%

Given data,

A bond has a $1,000 par value, 12 years to maturity, and an 8% annual coupon and sells for $980,

Par Value = $1,000

Annual Coupon Amount = $80 [$1,000 * 8%]

Bond Price = $980

Maturity Years = 12 Years

To find its yield to maturity (YTM),

Therefore, Yield to Maturity

[YTM] = Coupon Amount + [(Par Value – Bond Price) / Maturity Years] / [ (Par Value + Bond Price) / 2 ]

          = [$80 + {($1,000 – $980) / 12 Years)] / [($1,000 + $980) / 2]

          = [($80 + $1.67) / $990]

          = [$81.67 / $980]

Jean-Auguste-Dominque Ingres believed history was the best subject for art, a preference that can be seen in his work Jupiter and Thetis

Jean Auguste Dominique Ingres was an early 19th-century painter with a long French name and a very famous teacher. Ingres was taught the art of painting by the great French master Jacques-Louis David. David epitomized the Neoclassical movement in art, which reinvigorated Greek and Roman forms, often in the styles of the Italian Renaissance, an earlier culture to venerate classical civilization.

Jupiter and Thetis is an 1811 painting by  Jean-Auguste-Dominique Ingres, in the Musée Granet, Aix-en-Provence, France. Painted when the artist was yet 31, the work severely and pointedly contrasts the grandeur and might of a cloud-born Olympian male deity against that of a diminutive and half-bare nymph. Ingres' subject matter is borrowed from an episode in Homer's Iliad when the sea nymph Thetis begs Jupiter to intervene and guide the fate of her son Achilles; who was at the time embroiled in the Trojan War, this show how he believed history was the best subject for art.

so, we really graph the EQUATION of the expression, in this case we'd graph then h y = x² + 2x + 1. and y = −x² + 4x + 1.

then we notice that on the equation of the left-hand-side, it has "y>", meaning that "y is greater than", but never equals to that parabola, so, the line is dashed, meaning the border of the parabola is not part of the shaded area, or TRUE region.

for the one on the right-hand-side, we have "y⩾" or "y is greater than or equals", so the line is a solid line, pointing out the border of that parabola is included in the shaded part or TRUE region.

to check what section is true or not true, well, we can always pick a point on either side and check, so for example hmmmm let's check for the left-hand-side, hmmm the point above the parabola say hmmmm (2 , 3), so x = 3 whilst y = 3

[tex]3 > (2)^2+2(2)+1\implies 3 > 4+4+1\implies 3 > 9\leftarrow \textit{is this true?}[/tex]

is 3 really greater than 9? well hell nope, so that's "false", so that region is the false region, thus is not shaded, that way we know the other region is the "true" region, and so that's the one we shade.

Step-by-step explanation:

The formula is [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

You have to plug in the information you are given, into the formula, and you will have: [tex]d=\sqrt{(2-(-1))^2 + (0-4)^2}[/tex]

Then simplify.

[tex]d=\sqrt{(3)^2+(-4)^2}[/tex]

[tex]d=\sqrt{9+16}[/tex]

[tex]d=\sqrt{25}[/tex]

And the square root of 25 is 5.

your slope is -50 and your equation of x = mp + b becomes

x = -50 * p + b

you want a linear relationship between x and p

that would be a straight line equation with the general form of y = mx + b

m is the slope

b is the y-intercept

since you x in terms of p, then:

let y = x

let x = p

the equation of y = mx + b is the same as the equation of x = mp + b after you replace y with x and x with p.

in the equation of x = mp + b, you have coordinate points in the form of (p,x)

since y = x and x = p, this is the same as the form of (x,y), which is the standard form of the linear equation coordinate points.

we'll work with x = mp + b and then later translate to y = mx + b for graphing purposes.

your standard form is x = mp + b with coordinate points of (p,x).

you have two coordinate points they are (3.5,25) and (3,50)

m is equal to slope which is equal to (y2-y1)/(x2-x1) which is then translated to (x2-x1)/p2-p1 when you replace y with x and x with p.

  assign (3.3,25) to (p1,x1) and assign (3,50) to (p2,x2) and the slope       equation becomes (50-25)/(3-3.5) which becomes 25/-0.5 = -50

your slope is -50 and your equation of x = mp + b becomes

The cheetah traveled 15.334 miles approximately.

SOLUTION:

Given, Suppose the cheetah sprinted at maximum speed for 8 minutes

Then, slowed to 40mph the next 8 minutes  

We have to find how far would the cheetah have traveled

Now, we know that, maximum speed of cheetah is 68 – 75 mph, as we want maximum we are taking 75 which greater than 68.

So, cheetah sprinted at 75 mph for 8 minutes and then sprinted at 40 mph for next 8 minutes.

First let us convert 8 minutes into hours,

Total distance traveled = distance traveled with 75 mph speed + distance traveled with 40 mph speed

Hence, the cheetah traveled 15.334 miles approximately

Triangle ABC is congruent to ADC.

Two triangles are congruent if all of their corresponding parts are congruent. This means that congruent triangles will have three pairs of congruent sides and three pairs of congruent angles.

Given information,

AB = AD

BC = CD

and

AB = AD

CB = CD

also

AC = AC (common sides)

Hence triangles ABC and ADC are congruent to each other.

Congruence in two or more triangles depends on the measurements of their sodes and angles. The three sides of a triangle determine its size and the three angles of a triangle determine its shape. Two triangles are said to be congruent if pairs of their corresponding sides and their corresponding angles are equal.

If the three angles and the three sides of a triangle are equal to the corresponding angles and the corresponding sides of another triangle, then both the triangles are said to be congruent.

In the question ,

the matrix is given as [tex]\left[\begin{array}{ccc}0&0&-2\\1&2&1\\1&0&3\end{array}\right][/tex] .

The eigen values can be determined by using the characteristic equation ,

|A - λI | = 0

So , [tex]\left|\begin{array}{ccc}0-\lambda&0&-2\\1&2-\lambda&1\\1&0&3-\lambda\end{array}\right| = 0[/tex]

simplifying the above determinant , we get

-λ [(2-λ)(3-λ) - 0| - 0 -2[0 -(2-λ)] = 0

-λ[λ² - 5λ + 6] + 4 - 2λ = 0

-λ³ [tex]+[/tex] 5λ² -8λ [tex]+[/tex] 4 [tex]=[/tex] 0

λ³ - 5λ² + 8λ -4 = 0

Substituting λ = 1 in the above equation ,

we get ,

0 = 0

So , yes λ = 1  is a factor of the equation.

So , the characteristic equation can be written as

(λ - 1)(λ² - 4λ + 4) = 0

(λ -1)(λ² - 2λ -2λ + 4) = 0

(λ - 1)(λ - 2)(λ - 2) = 0

Weight of cylinder in the air = 0.66N

Weight of cylinder when immersed in an unknown liquid = 0.26N

The volume of the cylinder : v = m /d

where , m is mass of cylinder and d is density

Mass of cylinder : m = g/W

Where , g is acceleration due to gravity = 9.8m/s²

And w is weight of cylinder in air = 0.66N

Substituting the values of g and w

Therefore , m = 9.8 / 0.66

=> m = 14.8 kg

So, Volume of cylinder = 14.8 / 2700

=> V = 5.481 ×  10⁻³m³

To calculate the density of liquid ,

Density of liquid  = Upthrust / (volume of object × acceleration due to gravity)

Upthrust of the liquid = 0.66 - 0.26

=> 4 × 10⁻¹N

Volume of cylinder = 5.481 ×  10⁻³m³

Acceleration due to gravity  = 9.8m/s²

Therefore , The density of unknown liquid = 4 × 10⁻¹N / (5.481 ×  10⁻³m³ × 9.8m/s²)

Rearranging the log
