Answer:
b) (x + 5)(4x^2 - 3).
Step-by-step explanation:
4x^3 + 20x^2 - 3x - 15
= 4x^2(x + 5) - 3(x + 5)
= (x + 5)(4x^2 - 3).
Answer:
C) 3.9 sec
Step-by-step explanation:
You have given the time formula; t = square root of d divided by square root of 4.9.
Well d = 75m
square root of 75 = 8.66
square root of 4.9 = 2.2
8.66 / 2.2 = 3.9363...
t = 3.9 sec
Hope this was hopeful! (give 5 stars if you understood) :) Good luck
☆Concept:-
The Question is based on the law of exponents .
The law to be used in this question is
Solution:-
Answer:
<em><u>Given :-</u></em>
Two legs of a rt. triangle : 8 and 10 respectively.
<em><u>To find :-</u></em>
Length of the hypotenuse
<em><u>Solution :-</u></em>
Using Pythagorean Theorem;
(hypotenuse)² = (8)² + (10)²
= 64 + 100
hypotenuse = √164
= 12.8 units
F(x) = x^4 - 3x^3 + 2x^2 - 2x + 5
(x - 3) is a factor of f(x), if f(3) = 0
f(3) = (3)^4 - 3(3)^3 + 2(3)^2 - 2(3) + 5 = 81 - 81 + 18 - 6 + 5 = 17
Therefore, (x - 3) is not a factor of x^4 - 3x^3 + 2x^2 - 2x + 5
