Answer:
The height of the tree is about 30 feet.
Step-by-step explanation:
tan(55) = h/21
*21 *21
21*tan(55)=h
29.99=h
h=29.99=30 feet
Y = x² - 10 x + 15 =
= (x² - 10 x + 25) - 25 +15=
= ( x - 5 )² - 10
Answer: B) y = ( x - 5 )²-10
vertex: (5, -10)
y - intercept: ( 0,15)
Answer:
<h3>From the given monomials we have that <u>
</u> is the first term of the expression below to create a polynomial with a degree of 5 written in standard form.</h3>
Step-by-step explanation:
Given expressions are 
<h3>To find the first term of the expression below to create a polynomial with a degree of 5 written in standard form :</h3>
- From the given expressions we notice that they are monomials because it has one term only.
<h3>From the monomials we have that
is the first term of the expression below to create a polynomial with a degree of 5 written in standard form</h3>
- While other expressions exceeds degree 5 or less than the degree 5 so we take only this expression
- When we add the powers we get 4+1=5
- Therefore the degree of the polynomial is 5
Im Guessing this is a true and fasle
So the answer would be False
Answer:
14
Step-by-step explanation:
Ordinarily, a quick multiplication of 7 by other integers up to 10 indicates that only 7*9 yields 63, i.e ends with 3 as required.
Thus the set of possible multiples of the integer 7 ending with the digit 3 will form the arithmetic series with the first term being Ao = 63 and the common difference being d= 7*10= 70. That is we can see the series in details....
the nth term could be evaluated from the formular
An=Ao+(n-1)d (1)
The series could be explicitly depicted as follows:
9*7=63= 63+70*0
(10+9)*7=133 = 63+70*1
(20+9)*7=203=63+70*2
(30+9)*7=273=63+70*3
.................................
(130+9)*7=973=63+70*13
The last 'n' corresponding to the problem statement could be evaluated from equation (1), assuming An=1000:
1000=63+(n-1)*70
1000-63=70(n-1)
937/70=13.38=n-1
n=14.38
Thus the number of possible multiples of 7 less than 1000 ending with digit 3 will be 14.
Check: 7 times 142 is 994, so there are exactly 142 positive multiples of 7 less than 1000.
One tenth of these, ignoring the decimal fraction, end with a digit of 3.
