Which of the following expressions correctly uses the properties of summations to represent
madam [21]

Answer:

Option C is correct.

7 \cdot \sum_{i=1}^{18} i^2 + 9 \cdot 18

Step-by-step explanation:

Given the expression:  \sum_{i=1}^{18} (7i^2+9)

Using properties of summation:

  • \sum_{i=1}^{n} (a+bi) =\sum_{i=1}^{n} a + \sum_{i=1}^{n} bi
  • \sum_{i=1}^{n} a = an

Using properties of summation in the given expression we have;

\sum_{i=1}^{18} (7i^2+9)

= \sum_{i=1}^{18} 7i^2 + \sum_{i=1}^{18} 9

=7 \cdot \sum_{i=1}^{18} i^2 + 9 \cdot 18

Therefore, the following given expression uses the properties of summation to represents is, 7 \cdot \sum_{i=1}^{18} i^2 + 9 \cdot 18

PLEASEE HELPP....Simplify the expression using properties of exponents.​
Aleks04 [339]

Answer:

D

Step-by-step explanation:

Using the rule of exponents

\frac{a^{n} }{a^{m} } = \frac{1}{a^{(m-n)} }

Given

\frac{25a^{-5}b^{-8}  }{5a^{4}b }

= \frac{25}{5} × \frac{a^{-5} }{a^{4} } × \frac{b^{-8} }{b^{1} }

= 5 × \frac{1}{a^{(4-(-5))} } × \frac{1}{b^{(1-(-8))} }

= 5 × \frac{1}{a^{9} } × \frac{1}{b^{9} }

= \frac{5}{a^{9}b^{9}  } → D

Find the area of the figure. Use 3.14 for A.
Masteriza [31]

Answer:

38.13 m^2

Step-by-step explanation:

the area of a triangle =b*h/2

b=base

h=height

area triangle=(4m*3m)/2=(12m^2)/2=6m^2

the area of a rectangle =b*h

b=base

h=height

area of a rectangle=6m*3m=18m^2

area of a semi circle=(pi*r^2)/2

r=radius

area of a semi circle==(3.14*(3m)^2)/2=14.13m^2

area of the figure=6m^2+18m^2+14.13m^2=38.13m^2

the answer is 38.13m^2
