Step-by-step explanation:
3^5= 243
3^-1 = 0.3333333
243* 0.33= 80.19
Answer:
= 3 3/4 m^2
or 15/4 m^2
Step-by-step explanation:
The base is the triangle.
A =1/2 bh
A = 1/2 (3 1/3 * 9/4)
Change 3 1/3 to an improper fraction (3*3+1)/3 = 10/3
A = 1/2 * 10/3 *9/4
Re arranging
= 1/2* 9/3 * 10/4
= 1/2 (3) 5/2
=15/4
Now writing as a mixed number
= 3 3/4 m^2
Answer:
E: 22%
Step-by-step explanation:
Area of the whole page:
30 × 40 = 1200cm²
Area of inner page (excluding margins):
(30-4) × (40-4) = 26 × 36
= 936cm²
Area of margins:
1200 - 936 = 264
To find percentage: 
× 100 = 22%
Step-by-step explanation:
they're similar since 36 % 9 = 0 and 24 % 6 = 0 (they leave no remainder)
Please write this polynomial as P(x) = <span>-2x^4+24x^2-10, using " ^ " to denote exponentiation.
This is a fourth degree polynomial, since the highest power of x is 4. Ordinarily, a fourth degree poly would have 5 terms, but here two of the coefficients of the powers of x are zero, leaving only 3 terms.
</span>The lead coeff. of P(x) = -2x^4+24x^2-10 is -2.
The constant terms is -10. The exponent of x here is zero (0).
The degree of the middle term is 2 (see 24x^2, above)
Would you please post your other questions separately. Thank you.
