Evaluate the dot product of (7, 5) and (- 5, 4)

melamori03 [73]

Answer:

The dot product of (7,5) and (-5,4) is -15

Step-by-step explanation:

Given

(7,5) and (-5,4)

Required

Determine the dot product

Dot product is calculated using the following formula;

$a.b = {a_1b_1+a_2b_2+...+a_nb_n}$

Let a = (7,5) and b = (-5,4);

The above formula becomes

$a.b = {7*-5+5*4}$

$a.b = {-35+20}$

$a.b = {-15}$

Hence, the dot product of (7,5) and (-5,4) is -15

Someone please help me

hichkok12 [17]

Answer:

364.8 ft^2.

Step-by-step explanation:

I assume you want the area of the figure.

Total area = area of the top triangle + area of the trapezium

= 1/2 * base * height + 1/2 * height * ( sum of the parallel sides)

= 1/2 * 18 * 6 + (14/2)( 18 + 26.4)

= 54 + 310.8

= 364.8 ft^2.
