Answer:

t = − √ 2 a ( − h + 1 )/ a

Step-by-step explanation:

The solution to the given equation is t = √-2(h + 1)/a for "t" as a subject.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question following as:

h = - 1/2at² + 1

We have to determine the solution to the given equation for t as a subject.

As per the given question, we have

⇒ h = - 1/2at² + 1

Rearrange the terms in the above equation,

⇒ 1/2at² = - h + 1

Multiply by 2 both sides of the equation,

⇒ at² = -2(h + 1)

Divided by "a" both sides of the equation,

⇒ t² = -2(h + 1)/a

⇒ t = √-2(h + 1)/a

Thus, the solution to the given equation is t = √-2(h + 1)/a for "t" as a subject.

The value of  sin (345)=  (-sqrt6 + sqrt2)/4=  -0.2588

Trigonometry, the area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

Given:

sin (345)

Now, using Trigonometric identity

sin(a+ b)=sin a x cos b+ sin b x cos a

Now, expand 345= 300+ 45

sin(300 + 45)=sin 300 x cos 45+ sin 45 x cos 300

sin(300 + 45)= -√3/2 x √2/2 + √2/2 x  1/2

                     = -√6/4 + √2/4

                    =  -0.2588

Hence, sin (345)=  -0.2588

Complete question :

Taylor earns $5 each time she walks her neighbor's dog. She has already earned $25. Write and solve an equation to find out how many more times Taylor needs to walk the dog to earn enough to buy a bike that costs $83.

Answer:

12

Step-by-step explanation:

Amount earned for walking dog = $5 per walk

Amount already earned = $25

How many more times dog needs to be walked to buy a bike which costs $83

Target amount = 83

(Target amount - already earned amount) / amount earned per Walk

(83 - 25) / 5

58 / 5

= 11.6

Hence, Taylor needs to walk her neighbor's dog 12 more times

Answer:

The slope of the descent is 0.12 rounded to the nearest hundredth

Step-by-step explanation:

The given parameters are;

The vertical distance of descent of Bobba Dean = 1600 feet

The horizontal distance Bobba Dean has moved from the mountain high point = 2.5 miles

1 mile = 5,280 feet

∴ 2.5 miles = 2.5 × 5,280 feet = 13,200 feet

The slope of the descent = (The change in vertical elevation of Bobba Dean)/(The change in horizontal position from the high point of the mountain, by Bobba dean)

∴ The slope of the descent = (1600 feet descent)/(13,200 feet) = 4/33

The slope of the descent = 4/33 = 0.12 rounded to the nearest hundredth

Answer:

yes

Step-by-step explanation:

yes

Step-by-step explanation:

Let:-

[tex]p = {q}^{r}[/tex]be eqn.1

[tex]q = {r}^{p} [/tex]be eqn.2

[tex]r = {p}^{q} [/tex]be eqn.3

Susbstituting the value of p from eqn.1 to eqn.3 ,

[tex]r = {( {q}^{r} )}^{q} \: = {q}^{qr} [/tex]

Substituting the value of q from eqn.2 to eqn.3 ,

[tex]r = ( { {r}^{p} )}^{qr} = ( {r})^{pqr} [/tex]

[tex] = > {r}^{1} = {r}^{pqr} [/tex]

As bases are same in both the sides of this eqn.

[tex] = > pqr = 1[/tex]

We can easily prove the statement that if [tex]p=q^{r}[/tex], [tex]q = r^{p}[/tex] and [tex]r=p^{q}[/tex] , then pqr=1.

We know that a number's exponent indicates how many times it should be multiplied.

Given that

[tex]p=q^{r}[/tex]

[tex]q = r^{p}[/tex]

Now, [tex]r=p^{q}[/tex]

i.e. [tex]r=(q^{r})^{q}[/tex]

i.e. [tex]r=(q^{qr})[/tex]

i.e. [tex]r=(r^{p})^{rq}[/tex]

i.e. [tex]r=(r^{pqr})[/tex]

i.e. [tex]\frac{r}{r^{pqr}} =1[/tex]

i.e. [tex]r^{1-pqr} =r^{0}[/tex] [Since [tex]a^{0} = 1[/tex], a is any number]

i.e. 1 - pqr = 0

i.e. pqr = 1

We proved our statement that if [tex]p=q^{r}[/tex], [tex]q = r^{p}[/tex] and [tex]r=p^{q}[/tex], then pqr=1.

Answer:

-4/3 m/s

Step-by-step explanation:

Using Pythagoras :

a² = x² + c²

5² = x² + y² - - - (1)

The horizontal distance x with respect to time t = 1m/sec

dx/dt = 1m/sec

To obtain the vertical height 'y' with respect to time t when x = 4

5² = x² + y²

Wen x = 4

5² = 4² + y²

25 = 16 + y²

y =√(25 - 16)

y = 3

Differentiate (1) with respect to t

x² + y² = 25 - ---- - (1)

2x * dx /dt + 2y dy/dt = 0

dx/dt = 1

x = 4.

y = 3

2(4)(1) + 2(3) * dy/dt = 0

8 + 6dy/dt = 0

6 dy/dt = - 8

dy/dt = - 8/6

dy/dt = - 4/3
