Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was −190 feet. Then she continued to hike down for another 20 minutes at a different rate. Her change in elevation for this part of the hike was −200 feet. During which portion of the hike was her rate of change in elevation greater? Complete the explanation. Her rate was faster in the (Select: First, Second) part of the hike, because her heart rate was ____ ft/min in the first part and ___ ft/min in the second part.

Answers

Answer 1

Answer:

Her rate was faster in the FIRST because her rate was - 19 ft/ minutes in the FIRST PART and - 10ft/minute in the SECOND part

Step-by-step explanation:

Portion 1

Time taken to hike down = 10 minutes

Change in elevation = - 190 ft

Portion 2

Hiked down for further 20 minutes

Change in elevation = - 200ft

During which portion of the hike was her rate of change in elevation greater?

Rate of change in elevation :

Change in elevation / time

Portion 1:

Rate of change in elevation :

Change in elevation / time

- 190 ft / 10 minutes = - 19 ft/minutes

Portion 2:

Rate of change in elevation :

Change in elevation / time

- 200 ft / 20 minutes = - 10 ft/minutes

Her rate was faster in the FIRST because her rate was 19 ft/ minutes in the FIRST PART and 10ft/minute in the SECOND part

2ax - 15 = 3(x + 5) + 5(x - 1) In the equation above, a is a constant. If no value of x satisfies the equation, what is the value of a ?
NEED EXPLANATION!​

Answers

Answer:

Step-by-step explanation:

Hello,

let s regroup the terms

2ax - 15 = 3(x + 5) + 5(x - 1) *** add 15 to both sides ***

<=> 2ax = 15 + 3x + 15 + 5x - 5 *** develop to remove the parentheses***

<=> 2ax = 8x + 25 *** simplify ***

<=> (2a-8)x = 25 *** subtract 8x from both sides ***

<=> (a-4)x=25/2 *** divide by 2 both sides ***

There is no solution is a-4 = 0 ,

because it would mean 0 = 25/2 and this is not possible

So it gives a = 4

Thanks

In the case when no value of x satisfies the equation so there the value of a should be 4.

Calculation of the value of a:

Since

the equation is  

2ax - 15 = 3(x + 5) + 5(x - 1)

2ax = 15 + 3x + 15 + 5x - 5

2ax = 8x + 25

(2a-8)x = 25

So a = 4

hence, In the case when no value of x satisfies the equation so there the value of a should be 4.

Gregoria borrowed $2,450, to be paid back at 3.5% simple interest. She repays $3221.75. How many years was the loan period?

Answers

Answer:

90.7yrs.  

Step-by-step explanation:

Given parameters:

Amount borrowed  = $2450

Interest rate  = 3.5%

Amount repaid = $3221.75

Unknown:

Number of years the load was paid  = ?

Solution:

The formula of simple interest;

    I = PRT

Where I is the interest

           P is the principal

          R is the rate

          T is the time

  To find the interest;

    Interest = Amount paid back - loan  = 3221.75 - 2450  = 771.75

Now;

     P = IRT

     2450  = 771.75 x [tex]\frac{3.5}{100}[/tex]  x T

     2450 = [tex]\frac{2701.25T}{100}[/tex]

    T = [tex]\frac{245000}{2701.125}[/tex]   = 90.7yrs

The number of years of the loan period was 90.7yrs.

There are two twins. One twin wants to explore the planet near Proxima Centauri and leaves on a spaceship traveling at 90% of the speed of light, while the other twin stays home on Earth. How much does the twin on Earth age while the other twin travels to Proxima Centauri?

Answers

Answer:

4.7 years

Step-by-step explanation:

Distance of planet from Earth = 1.3 parsec

We know that 1 parsec = 3.26 light years

And a light year is the distance traveled by light in time period of 1 year.

So, Distance of planet from Earth = 1.3 [tex]\times[/tex] 3.26 = 4.24 light years

Given that, the person travels at a speed equal to 90% of the light speed.

To travel to the planet from Earth, Light takes 4.24 years.

To travel the distance [tex]D[/tex], at a speed [tex]s[/tex] light takes time of 4.24 years.

To travel the distance [tex]D[/tex], at a speed [tex]0.90s[/tex], the person takes time:

[tex]\dfrac{4.24}{0.90} = \bold{4.7\ years}[/tex]

So, the twin on Earth ages by 4.7 years.

The volume V of a solid right circular cylinder is given by V = πr2h where r is the radius of the cylinder and h is its height. A soda can has inner radius r = 1.5 inches, height h = 6 inches, wall thickness 0.04 inches, and top and bottom thickness 0.07 inches. Use linearization to compute the volume, in cubic inches, of metal in the walls and top and bottom of the can. Give your answer to 2 decimal places.

Answers

Answer:

8.20in³

Step-by-step explanation:

Given V = πr²h

r is the radius = 1.5in

h is the height = 6in

thickness of wall of the cylinder dr = 0.04in

top and bottom thickness dh 0.07in+0.07in = 0.14in

To compute the volume, we will find the value of dV

dV = dV/dr • dr + dV/dh • dh

dV/dr = 2πrh

dV/dh = πr²

dV = 2πrh dr + πr² dh

Substituting the values into the formula

dV = 2π(1.5)(6)•(0.04) + π(1.5)²(6) • 0.14

dV = 2π (0.36)+π(1.89)

dV = 0.72π+1.89π

dV = 2.61π

dV = 2.61(3.14)

dV = 8.1954in³

Hence volume, in cubic inches, of metal in the walls and top and bottom of the can is 8.20in³ (to two dp)
