1. P = 18+24+17+7+9+9 = 84
A = (7x9) + (18x17) = 369

2. P = 16+22+11+7+9+11 = 76
A = (16x11)+(11x15) = 341

3. P = 10+14+29+24+14+19 = 110
A = (24x19) + (14x14) = 652

4. P= 10+17+15+7+9+8 = 66
A=(15x10)+(8x9) = 222

5. P = 13+16+19+10+26+32 = 116
A = (13x10)+(32x16) = 642

6. P = 32+31+19+20+12+12 = 126
A = (31x12)+(20x12)= 612

Expression A: (2k + 8) + (5k + 10)

Dmitriy789 [7]

k = 3

Expression A:

$(2k + 8) + (5k + 10) = 2k + 8 + 5k + 10 = 7k + 18 = 7*3 + 18 = 21 + 18 = 39$

Expression B:

$76 + 18= 94$

Like charges repel and I like charges attract Coulomb’s law states that the force F of attraction or repulsion between two charg

olga_2 [115]

Step-by-step explanation:

For the charges that have same sign of charges will repel each other while for the charges that have different charges will attract each other. So, we can say that like charges repel and unlike charges attract each other.

The Coulomb's law of attraction of repulsion states that force between charges is directly proportion to the product of charges and inversely proportional to the square of distance between them. Mathematically, it is given by :

$F=\dfrac{kq_1q_2}{r^2}$

Hence, all the given statements are true.

Find the exact value of sec theta if csc theta = -4/3 and the terminal side of theta lies in quadrant III

GREYUIT [131]

Answer:

-4 sqrt(7)/7

Step-by-step explanation:

csc theta = -4/3

csc theta = hypotenuse / opposite side

hypotenuse = 4

opposite = 3

Using the pythagorean theorem

a^2 + b^2 = c^2

3^2 + b^2 = 4^2

9+b^2 = 16

b^2 = 16-9

b^2 = 7

Taking the square root

sqrt(b^2) = sqrt(7)

b = sqrt(7)

We are in the third quadrant so only tan and cot are positive

that means the x and y values are "negative" so a = -3 and b = - sqrt(7)

sec theta = hypotenuse / adjacent

= 4/ - sqrt(7)

rationalizing

-4 sqrt(7)/ sqrt(7)* sqrt(7)

= -4 sqrt(7)/7
