I disagree. The first one is false. No exponent rules apply if the bases AND the exponents are different.

The second one is true. Bases are the sane so you add exponents. You get 3 to the -5 power. Written with positive exponents it’s 1/3 to the 5.

rewrite the polynomial 2y^2+ 6y^3-11-17y^4+8y^5 in the standard form also find its degree and coefficient of y^4
OleMash [197]

Answer:

The standard form is  8 y ⁵ - 17 y⁴ + 6 y³ +2 y² - 11

The degree of given polynomial is '5'

the co-efficient of  y⁴  is '-17'

Step-by-step explanation:

Given standard form 2 y²+ 6 y³-11-17 y⁴+8 y⁵

<em>The form ax² + b x + c is called the standard form of the quadratic expression of 'x'.This is second degree standard form of polynomial.</em>

<em>The form ax⁵ + b x⁴ + c x³ +d x² +ex +f  is called the standard form of the quadratic expression of 'x'.This is fifth degree standard form of polynomial</em>

now Given polynomial is  2 y²+ 6 y³-11-17 y⁴+8 y⁵

The standard form is

                                8 y ⁵ - 17 y⁴ + 6 y³ +2 y² - 11

<u><em>Conclusion</em></u>:-

<em>The degree of given polynomial is '5'</em>

<em>The co-efficient of  y⁴  is '-17'</em>

Need answers before 8pm!!
GaryK [48]

We have similar triangles so

12/x = (12+78)/(x+13)

We can skip some algebra by doing the ratio on the pieces.  We'll show it works at the end.

12/x = 78/13

x = 12(13)/78 = 2

We check

12/2 = 6

(12+78)/(2+13) = 90/15 = 6, good

Answer: x=2

Jim borrows $14,000 for a period of 4 years at 6 % simple interest. Determine the interest due on the loan. [4 marks
tino4ka555 [31]

Answer: $ 3,360

Step-by-step explanation:

Given : The principal amount borrowed for loan : P=\ \$14,000

Time period : t=4

Rate of interest : r=6\%=0.06

The formula to calculate the simple interest is given by :-

S.I.=P\times r\times t\\\\\Rightatrrow\ S.I.=14000\times4\times0.06\\\\\Rightatrrow\ S.I.=3360

Hence, the interest due on the loan = $ 3,360
