1. The velocity of a car as it travels over a level crossing is modeled by v = t2 – 4t + 12

for 0 < t < 4 where t is the time in seconds after it reaches the crossing. When does the car reach its minimum speed? What is the minimum speed?

Show your work or strategy:

When does the car reach its minimum speed? _________________

What is the minimum speed? _________________________

Answers

Answer:

At t=2s the car reach its minimum speed

Minimum speed=8m/s

Step-by-step explanation:

We are given that velocity of car

[tex]v(t)=t^2-4t+12[/tex]

0<t<4

Differentiate w.r.t t

[tex]v'(t)=2t-4[/tex]

[tex]v'(t)=0[/tex]

[tex]2t-4=0[/tex]

[tex]2t=4[/tex]

[tex]t=2[/tex]

[tex]v''(t)=2>0[/tex]

The velocity is minimum at t=2 s

Substitute t=2

[tex]v(2)=2^2-4(2)+12[/tex]

[tex]v(2)=8m/s[/tex]

Hence, the speed of car is minimum at t=2 se and minimum speed of car=8m/s

tom and ben ordered a pizza for lunch. they each ate 1/3 of the pizza. how much pizza was eaten and how much pizza was left?

Answers

Answer:

they ate 1/3 and thrte is 2/3 left

Step-by-step explanation:

subtraction

One-third of the pizza will be left

Proportions and Ratios

Let the total amount of pizza eaten be "x

Amount of pizza ate by Tom is 1/3 xAmount of pizza ate by Ben is 1/3 x

Total pizza ate = x/3 + x/3

Total pizza eaten = 2x/3

Amount of pizza left = x - 2x/3

Amount of pizza left = (3x-2x)/3

Amount of pizza left = x/3

Hence one-third of the pizza will be left

2) 1) A 6 ft tall lawn ornament standing next to a baby elephant casts a 18 ft shadow. If the baby elephant casts a shadow that is 12 ft long, then how tall is it?

Answers

Answer: 4 feet.

Step-by-step explanation:

Proportion from lawn ornament to its shadow = 6ft : 18ft = 1 : 3

Proportion from baby elephant to its shadow = x : 12ft

These proportions have to be equal, because if it is the same time of day, the different object's shadows will have the same proportions.

In order to solve this problem, we need to cross multiply. (Attached image)

So, 3x = 12.

By solving this equation, we find that x = 4

The height of the baby elephant is 4 feet.

1/4 + 2/3 = equals what

Answers

The answer to your question is 11/12

1/4 + 2/3 = 11/12 because you need to find the common denominator which is 12. You have to multiply 1/4 by 3 to get the denominator of 12, so it becomes 3/12. Then, you have to multiply 2/3 by 4 to get the denominator of 12 which gives you 8/12 so you add 3/12 + 8/12 and you get 11/12.

Which inequality is equivalent to this one? y-85-2

Answers

Answer:

[tex]y-8+2\leq -2+2[/tex]

Step-by-step explanation:

Since you're adding either 8 or 2 to both sides, the inequality sign doesn't change.

So we can eliminate the first and second choice.

Now it's down to the bottom two.

The third choice is adding 2 to the left hand side and then adding 8 to the right hand side. You can't add two different numbers to different sides.

Therefore, the last one must be the correct answer.

The last one is adding two to both sides and have the same inequality sign.

One of the legs of a right triangle measures 4 cm and the other leg measures 19 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.

Answers

Answer:

A2 + B2 = C2, so 4 squared + 19 squared = C2, 16 + 361 = 377. 377's square root is 19.4.

Step-by-step explanation:

The measure of the hypotenuse is 19.4 cm.

Given that, one of the legs of a right triangle measures 4 cm and the other leg measures 19 cm.

What is the Pythagoras theorem?

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Let the measure of the hypotenuse be x.

Using Pythagoras theorem,

x² = 4² + 19²

⇒ x² = 16 + 361

⇒ x² = 377

⇒ x = √377

⇒ x = 19.4 cm

Therefore, the measure of the hypotenuse is 19.4 cm.
