If the circumference of a circle is 15 pie inches, then what is its diameter

maria [59]

(-4) is the same as x, so looking the conditions that are the results for the function, you realize:

-2 is the result of the function to the values of X that are under -3: the result will be -2 if x < -3

x < -3 ; x = -4 ; -4 < -3 (it's true), in other words, -4 is less than -3, so f(-4) = -2

Please help Math question 50 points! An employer provides two payment options for employees. Option A: Receive $200 the first we

dezoksy [38]

Answer:

it could be and to show his number two because it's running all those numbers up over and over again by percentage is that the end is going to give you a big number

Step-by-step explanation:

on the beginning is adding 200 + 50 we should give you 250 then is a 200 more so it was equals to 450 but then he asked you per week you get 50 extra so is basically 50 x 6 cylinder 6 weeks and I will give you a promise off $300 $300 + 450 equals to 750 each week is 10% so is basically equals to 50 so 50 + 50 + 50 + 50 or the easiest way is 50 * 6 I would go with answer to like I said because it's showing like a little of of a conversation was not given in any Solution on a specific number and that's the most closest one to like the whole problem

Place the numbers in order from greatest to least.90.9890.08990.989.8990

padilas [110]

EXPLANATION:

The decimal number that is greater is the one with the largest integer part. If they have the same integer part, the first different decimal place is compared.

Now we are going to order the numbers of the exercise,

The correct order is:

-90.98

-90.9

-90.089

-90

-89.89

3. A model rocket is launched from the ground with an initial velocity of 352 ft/sec.

Hoochie [10]

Answer:

e. It will take 11 seconds to reach the maximum height of 1,936 feet.

f. It will take 22 seconds to return to the earth.

Step-by-step explanation:

Given:

Initial velocity $v_0$ = 352 ft/sec

Solving for question e.

To find the time required to reach the maximum height we will use the formula,

$h(t) = -16t^2+v_0t+h_0$ ,

where $v_0$ is the starting velocity

$h_0$ is the initial height.

Using the velocity and starting height from our problem we have,

$h(t) = -16t^2+352t+0$ ,

The path of this rocket will be a downward facing parabola, so there will be a maximum.

This maximum will be at the vertex of the graph.

To find the vertex we start out with $x= \frac{-b}{2a}$ which in our case is,

$x=\frac{-352}{2(-16)}=\frac{-352}{-32}= 11$

So, It will take 11 seconds for the rocket to reach its maximum height.

We will find maximum height using the formula by substituting value of t we get,

$h(11)=-16(11^2)+352(11)+0\\h(11) = -16 \times121+ 352 \times 11 = -1936+3872= 1936 \ ft$

Hence the maximum height will be $1936 \ ft$

Now Solving for question f.

To find the time required for rocket to reach earth.

We will set our formula to 0 to find the time.

$0= -16t^2+352t+0\\-16t(t-22)=0$

Using the zero product property, we know that either -16t = 0 or t - 22 = 0. When -16t = 0 is at t = 0, when the rocket is launched. t - 22 = 0 gives us an answer of t = 22.

So the rocket reaches the Earth again at 22 seconds.
