A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using the equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second y=-16x^2+235x+133
Answers
Answer:
Step-by-step explanation:
Given tq equation of the height reached by the rocket as y=-16x^2+235x+133
The velocity of the object at its maximum height is zero
v = dy/dx = 0(at max height)
v =-32x +235
0 =-32x+235
x = 235/32
x = 7.34
Hence the rocket will reach its maximum height after 7.34seconds

The answers are:
2/9 and 7/2
Step-by-step explanation:
The reciprocal of a number is a special number such that, when multiplied by the original number, gives us 1.
And we know that in fractions, to get from a/b to 1, we should multiply a/b times b/a.
So this leads to the conclusion that the reciprocal of 9/2 is 2/9 and the reciprocal of 4/7 is 7/2.

Joe owns a dirt bike shop. He bought a dirt bike at cost for $252. If he marks up the price by 60%, what is the retail amount of the bike? (Reminder you are working with money and need to round to 2 decimal places). The amount of Markup is $ . The retail amount is $
Answers
Given:
Cost of bike = $252
Markup % = 60%
To find:
The markup and retail amount.
Solution:
According to the question,
Markup = 60% of cost of bike
[tex]Markup=\dfrac{60}{100}\times 252[/tex]
[tex]Markup=0.6\times 252[/tex]
[tex]Markup=151.2[/tex]
Now,
[tex]\text{Retail amount}=\text{Cost + Markup}[/tex]
[tex]\text{Retail amount}=252+151.2[/tex]
[tex]\text{Retail amount}=403.2[/tex]
Therefore, the amount of Markup is $151.2. The retail amount is $403.2.

17x+5 and 18x are corresponding angles and because we have parallel lines these two angles are congruent.

17x+5=17*5+5=85+5=90°
how to factorise 8a3-b3
Answers
Answer:
Step-by-step explanation:
Answer:
(2a - b)(4a² + 2ab + b²)
Step-by-step explanation:
8a³ - b³ ← is a difference of cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , thus
8a³ - b³
= (2a)³ - b³
= (2a - b)((2a)² + 2ab + b² ), that is
(2a - b)(4a² + 2ab + b²)

Keirra wants to buy 12 bagels. She uses partial products to find her total. She says $ 16.80 is close to my estimate of 12 x 1=12, so this total is reasonable. Do you agree with her? Explain your reasoning.
Answers
Answer:
$11.40, is the actual price, so no
Step-by-step explanation:
If a bagel is $0.95 cents, then multiply that by 12, that would be $11.40, so no, her total is not reasonable, even if you round $0.95 to a dollar, 12x1 would be 12, so you can't estimate that to $16.80

Step-by-step explanation:
Fact regarding the centroids of a triangle.
On each median the distance from the vertex to the centroid is twice the distance from the centroid to the midpoint, thus
BD = 2DE, that is
4 = 2DE ( divide both sides by 2 )
DE = 2
Thus
BE = BD + DE = 4 + 2 = 6

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.
so you must first find what is the x and which one is the y in the function then you will find the answer when you solve the problem
