Answer:

At 3.44 seconds, the penny is at a height of 300 meters above the ground.

Step-by-step explanation:

Basically, we have to solve an equation here:

-4.9t^{2} + 358 = 300

Hence,

-4.9t^{2} = 300 - 358

t^{2} = \frac{-58}{-4.9}

t = 3.44

Hence, at 3.44 seconds, the penny is at a height of 300 meters above the ground.

Hope this helped!

R-7=7 add the seven from both sides, leaving the r alone, because this is what you are trying to find. Thus the answer is r=14.

Identify the name and label the parts of the following polynomial: − 2x^4+24^2-10
lianna [129]
-2x^4 + 24x^2 - 10

u have 3 terms.....and since u are only dealing with 1 variable with the highest exponent being 4, then what u have here is a 4th degree trinomial.
U have a lead coefficient of -2.
Ur constant term is -10
And ur middle term (24x^2) has a degree of 2

a cubic binomial.....a binomial has 2 terms and it being cubic means the highest term has a degree of 3
example would be : x^3 - 4

how many constants can a polynomial have ? I am not sure about this one...I wanna say 1 because u can simplify it if it has more then 1...but I am not 100% sure on this one

3x^2 + 6xy -10x^5 + y^6 - 10x^3y^5

when u have a polynomial with more then 1 variable, such as this one, the degree is not the highest exponent, it is the highest term.....-10x^3y^5...u add the exponents....so this term has a degree of 8, and it is the highest one in this problem....so this is an 8th degree polynomial with 5 terms

Anybody know the answer?
Dmitry_Shevchenko [17]

Answer:

<h2><em><u>Option</u></em><em><u> </u></em><em><u>B</u></em><em><u> </u></em></h2>

Step-by-step explanation:

<em><u>As</u></em>,

It has shown that line c cuts line b by making 90° so those lines are called <em><u>perpendicular bisectors </u></em><em><u>.</u></em>

<em><u>Hence</u></em>,

<em>Option B is the correct symbol shown for perpendicular bisector of line </em><em>c</em><em> </em><em>to line </em><em>b</em><em>.</em>
