I only have 8 minutes left please help!!! The expression h(x)= -5x2 + 25x + 70 can be used to estimate the height(h), in meters, of a toy rocket x seconds after it is launched from
a platform. Substitue 0 for h in the equation, and determinehow many seconds it will take for the rocket to hit the ground? Enter the
answer that makes the most real world sense for the scenario described.

Answer:

pi/2

Step-by-step explanation:

The arc length is based on the circumference

c = 2 * pi *r

C = 2 * pi *1 = 2pi

This is 1/4 of the circle so the arc length given is 1/4 of the arc length

arc length = 1/4 ( 2pi)

                  = pi /2

Answer:

A 165° angle

Step-by-step explanation:

I zoomed in on the picture and it was a 165° angle

Answer:

NO

Step-by-step explanation:

an equivalent ration to 2:3 would be 10:15. because when you simpliy 10:15 the most you can you would get 2:3. where as 10:18 is not equal

Yes they are equivalent

Answer:

To find 2/3 of an hour first we will divide 1 hour that is 60 minutes into 3 parts. So we will get 20 minutes. So we 2parts out of 3 parts of an hour so we get 20X2=40minutes

Answer:

4 is the BASE and 5 is the EXPONENT

Step-by-step explanation:

Thx i needed this answer :P

The number 5 is the exponent or power and the number 4 is the base of the expression.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The exponential expression is given as,

⇒ (4)⁵

In the exponential expression aⁿ, the n is the exponent or power and a is the base of the expression.

Then in the exponential expression (4)⁵, the number 5 is the exponent or power and the number 4 is the base of the expression.

Answer:

  ∠B = ∠C = 138°

  ∠D = 42°

Step-by-step explanation:

Angles between the parallel bases are supplementary:

  ∠B = 180° -∠A = 180° -42° = 138°

Right-side angles are the same measure as their mirrors across the line of symmetry.

  ∠C = ∠B = 138°

  ∠D = ∠A = 42°

Answer:

y = - 2x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2 , then

y = - 2x + c ← is the partial equation

To find c substitute (3, - 4) into the partial equation

- 4 = - 6 + c ⇒ c = - 4 + 6 = 2

y = - 2x + 2 ← equation of line

Answer:

x = 47

Because the angles of a triangle add up to 180, you can just use subtraction to find out what the missing angle is.

A police officer can not punish air pollution but can enforce laws and regulations to protect the environment.

Air pollution means the presence of harmful substances in the air that can cause harm to all living beings.

We have,

Air pollution is not a living being so it can not be punished by a police officer.

A police officer or government authorities can enforce laws and regulations to reduce air pollution to protect all living beings and the environment.

Some of the measures are:

- Setting emissions standards for automobile and related industries

- Promoting the use of clean energy resources.

- Encouraging individuals and entities to adopt sustainable practices

Thus,

A police officer can not punish air pollution but can enforce laws and regulations to protect the environment.

The Answer is 400

Step-by-step explanation:

Answer:

0.9115

Step-by-step explanation:

Using a binomial probability function :

P(x =x) = nCx * p^x * (1 - p)^(n - r)

Probability of success, p = 0.55

1 - p = 1 - 0.55 = 0.45

n = 8

x = 2

P(x > 2 ) = p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7) + p(x =8)

To save computation time, we could use the binomial probability calculator :

P(x > 2 ) = 0.9115
