A car approaches a stop sign going 10 m/s before coming to a stop. If it takes 5 seconds to
do this, what is its acceleration

Answers

Answer 1

Answer:

The acceleration is: a = -2 m/s²

The negative sign indicates that velocity is decreasing with time.

Step-by-step explanation:

Given

Initial velocity u = 10 m/sFinal velocity v = 0Time taken t = 5 seconds

To determine

Acceleration a = ?

Using the formula to determine the acceleration

a = (v - u) / t

substituting u = 10 m/s, v = 0 and t = 5

a = (0 - 10) / 5

a = -10 / 5

a = -2 m/s²

Thus,

The acceleration is: a = -2 m/s²

The negative sign indicates that velocity is decreasing with time.

A taxi cab charges $3.00 per person
plus $1.25 per mile. What is the
greatest distance one passenger
could travel with a budget of
$28.00?

Answers

Answer:

20 miles

Step-by-step explanation:

Subtract $28.00 and $3.00

$25

Then divide $25.00 by $1.25

20miles

The one passenger can travel 20 miles in thus budget.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Charge of taxi cab per person = $3.0

And per miles = $1.25

Budget of passenger = $28.00

Now, We have to calculate the distance that passenger can travel.

The amount without taxi cab charge = 28 - 3 = $25

So the distance = 25 / 1.25 = 20 miles

Thus, The one passenger can travel 20 miles in thus budget.

Answers

Answer:

The third:    f(x) = x³ + 7x² - 5x - 35

Step-by-step explanation:

[tex]f(x)=(x-\sqrt5)(x+\sqrt5)(x+7)\\\\f(x)=(x^2+x\sqrt5-x\sqrt5-(\sqrt5)^2)(x+7)\\\\f(x)=(x^2-5)(x+7)\\\\f(x)=x^3+7x^2-5x-35[/tex]

Answer:

C. f(x) = x³ + 7x² - 5x - 35

Step-by-step explanation:

Given zeros of cubic function:

√5, -√5 and -7

The cubic function has standard form:

f(x) = ax³ + bx² + cx + d

Without multiplying lets find the value of a, b, c and d:

a = 1 as all the answer options

Sum of the roots

-b/a = √5 - √5 - 7 = -7, so b = 7

Sum of the products of the roots (taken two at a time)

c/a = √5*(-√5) + √5*(-7) + (-√5)(-7) = - 5, so c = -5

Product of the roots

- d/a = √5*(-√5)*(-7) = 35, so d = -35

So the cubic function is:

f(x) = x³ + 7x² - 5x - 35

Correct option is C

Dana bikes 10 miles in 50 minutes at this rate how far will she bike in 90 minutes

Answers

Answer:

18 miles

Step-by-step explanation:

the ratio is miles/minute

10/50=0.2

so no just multiply the amount of minute you want 0.2*90= 18 miles

Answer and Step-by-step explanation:

In an hour and a half, Dana would go 18 miles since she's going a mile at regular intervals, so if she's trekking for an additional forty minutes, she will bicycle 8 miles. This implies that you'd increase five minutes by 8 miles (recall it's a mile for every 5 minutes) and that would give you forty. At that point simply add that to the 50 minutes she's been cycling as of now.

Answer:

A

Step-by-step explanation:

well, you can plug in 6 for x to see if it comes out true. If it does. then yes 6 is a solution for the equation. If it doesn't, then it's no.

(6) + 13 = 18

19 = 18

So, the answer is no since 19 does not equal 18. So it's between A and B. Now you must read. Is it no because 6 + 13 = 18 is true or not true?

Well, since 19 does not equal 18, 6 + 13 = 18 is not true.

So the answer is A. No, because 6 + 13 = 18 is not true

Answer: i think A

Step-by-step explanation: 6+13 does not equal 18 it equals 19 that is
