Answer:

It takes more time on moon for the rock to fall.

Step-by-step explanation:

Given that:

Time it takes for rock to fall d meters on earth = √0.45d

Time it takes for rock to fall d meters on moon = √1.11d

For a rock to fall 50 meters:

On earth :

Time = √0.45*50 = 4.7434164 seconds

On moon :

Time = √1.11*50 = 7.4498322 seconds

Time on moon > Time on earth

Hence, It takes more time on moon for the rock to fall.

Ana runs at a speed of 7.5 miles per hour

Step-by-step explanation:

Speed

Is the rate at which the distance changes in time.

The formula to calculate the speed is:

[tex]\displaystyle v=\frac{d}{t}[/tex]

Where d is the distance traveled in time t.

We know Ana runs a distance of d=3/4 miles in 6 minutes, already converted to t=1/10 hours.

Thus, the speed is calculated as follows:

[tex]\displaystyle v=\frac{\frac{3}{4}}{\frac{1}{10}}[/tex]

Multiplying by the reciprocal of the denominator:

[tex]\displaystyle v=\frac{3}{4}\cdot \frac{10}{1}=\frac{30}{4}[/tex]

v=7.5 mile/h

Ana runs at a speed of 7.5 miles per hour

Answer:

A) The height of the water increases 2 inches per minute.

Step-by-step explanation:

Slope is the rate of change of height

m = (16 - 12)/(4 - 2) = 4/2 = 2

2 inch per min

Positive slope implies increase

Answer:

water world give lower priced offer

Step-by-step explanation:

Offer given by Aqua Plus

two-year membership for $479.76

it means,

for 24 month=$479.76

For 1 month=$

For 1 month membership Aqua Plus  take $19.99

Now Offer given by Water World

18-month membership for $350.00

it means for 18 month=$350.00

and For 1 month=$

For 1 month membership water world takes $19.44

it means amount taken by water world for 1 month membership is less than the amount taken for 1 month by Aqua plus

Therefore, water world give lower priced offer.

Answer:

D. Zn(NO3)2 + Cu

Step-by-step explanation:

The correct chemical equation for the replacement reaction of Cu(NO3)2 and Zn is:

Zn + Cu(NO3)2 → Zn(NO3)2 + Cu

A replacement reaction is a chemical reaction in which an element displaces or replaces another element in a compound. In other words, one element takes the place of another element in a compound.

The general equation for a replacement reaction is:

A + BC → AC + B

We have,

The reaction between copper nitrate (Cu(NO3)2) and zinc (Zn) is an example of a single replacement or displacement reaction, which involves the replacement of one element in a compound by another element.

In this reaction,

Zinc (Zn) reacts with copper nitrate (Cu(NO3)2) to form zinc nitrate (Zn(NO3)2) and solid copper (Cu).

The reaction is driven by the relative reactivity of the metals involved.

Zinc is more reactive than copper, which means that it has a greater tendency to lose electrons and form positive ions.

Copper, on the other hand, is less reactive and has a greater tendency to stay in its elemental form.

When zinc is added to copper nitrate solution, the zinc atoms lose electrons and become positively charged ions, while the copper ions in the solution gain electrons and become solid copper.

The zinc ions then combine with nitrate ions (NO3-) from the copper nitrate solution to form zinc nitrate, which remains in the solution.

The balanced chemical equation for the reaction shows that one molecule of zinc (Zn) reacts with one molecule of copper nitrate (Cu(NO3)2) to form one molecule of zinc nitrate (Zn(NO3)2) and one molecule of solid copper (Cu).

Thus,

The correct chemical equation for the replacement reaction of Cu(NO3)2 and Zn is:

Zn + Cu(NO3)2 → Zn(NO3)2 + Cu

Answer:

wheres the question??

Answer:

x=-2 solves the equation h(x)=10.

Step-by-step explanation:

Given the function

[tex]h\left(x\right)\:=\:2x^2\:-\:7x-12[/tex]

Putting [tex]h(x)=10[/tex] in the function

[tex]10=2x^2-7x-12[/tex]

switch both sides

[tex]2x^2-7x-12=10[/tex]

add 12 to both sides

[tex]2x^2-7x-12+12=10+12[/tex]

[tex]2x^2-7x=22[/tex]

Divide both sides by 2

[tex]\frac{2x^2-7x}{2}=\frac{22}{2}[/tex]

[tex]x^2-\frac{7x}{2}=11[/tex]

Rewriting in the form x²+2ax+a²

[tex]\mathrm{Add\:}\left(-\frac{7}{4}\right)^2\mathrm{\:to\:both\:sides}[/tex]

[tex]x^2-\frac{7x}{2}+\left(-\frac{7}{4}\right)^2=11+\left(-\frac{7}{4}\right)^2[/tex]

[tex]x^2-\frac{7x}{2}+\left(-\frac{7}{4}\right)^2=\frac{225}{16}[/tex]

[tex]\left(x-\frac{7}{4}\right)^2=\frac{225}{16}[/tex]

[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]

slove

[tex]x-\frac{7}{4}=\sqrt{\frac{225}{16}}[/tex]

[tex]x-\frac{7}{4}=\frac{\sqrt{225}}{\sqrt{16}}[/tex]

[tex]x-\frac{7}{4}=\frac{15}{4}[/tex]

[tex]\mathrm{Add\:}\frac{7}{4}\mathrm{\:to\:both\:sides}[/tex]

[tex]x-\frac{7}{4}+\frac{7}{4}=\frac{15}{4}+\frac{7}{4}[/tex]

[tex]x=\frac{11}{2}[/tex]

solving

[tex]x-\frac{7}{4}=-\sqrt{\frac{225}{16}}[/tex]

[tex]x-\frac{7}{4}=-\frac{15}{4}[/tex]

[tex]\mathrm{Add\:}\frac{7}{4}\mathrm{\:to\:both\:sides}[/tex]

[tex]x-\frac{7}{4}+\frac{7}{4}=-\frac{15}{4}+\frac{7}{4}[/tex]

[tex]x=-2[/tex]

The solutions to the quadratic equation are:

[tex]x=\frac{11}{2},\:x=-2[/tex]

Therefore, x=-2 solves the equation h(x)=10.

D'(-4, 1)

Step-by-step explanation:

Polygon ABCDEF is transformed by number of steps given in the question.

We have to find the coordinates of point D'.

Coordinates of point D → (2, -2)

Step - 1,

Polygon rotated 90° counterclockwise about the origin,

Rule for this rotation,

(x, y) → (-y, x)

Coordinates of image E after rotation,

D(2, -2) → E(2, 2)

Step - 2,

Point E then reflected across the line y = -x,

Rule for the reflection,

(x, y) → (-y, -x)

Image of E after reflection will be,

E(2, 2) → F(-2, -2)

Step -3,

Then point F was translated up by 3 units and 2 units left,

Rule for the translation,

(x, y) → (x -2, y + 3)

Image of F will be point D',

F(-2, -2) → D'(-4, 1)

Answer:

Inverse of cosine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction)

Step-by-step explanation:

According to trigonometry identity;

Cos 30° = √3/2

To get the expression equivalent to 30°, we will take the inverse of both sides as shown;

Cos^-1(cos 30°) = cos^-1(√3/2)

The arccos will cancel out the cos on the left hand side of the equation to have;

30° = cos^-1(√3/2)

Hence 30° is equivalent to inverse of cosine of √3/2 or Inverse of cosine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction)
