Answer:
2 numbers that multiply to make -21 = 3 x (-7)
2 numbers that add up to -4 = 3 - 7
Step-by-step explanation:
2 numbers that multiply to make -21 = 3 x (-7) = -21
2 numbers that add up to -4 = 3 - 7 = -4

Answer:
Step-by-step explanation:
The latte is what covered the coffee, Caffe latte is a coffee drink made with espresso and steamed milk, and this latte do form heart on the coffee, then we are told that the area of the latte heart is 55cm²
Then, space where latte is not form has a diameter 4cm
Then the radius is diameter divided by 2
r=d/2
r=4/2 =2
Then area of the circle which for the surface for the coffee is πr²
A=πr²
A=3.142×2²
A=12.568cm².
Area of coffee not covered is
55-12.568=42.432cm²
The dot product is used to determine the magnitude of the resultant vector of two component vectors. It is expressed as a·b. It does not literally mean that you multiply their values. Instead, you multiply their matrices. However, since we cannot find matrices, let's just find the resultant vector through theorems involving triangles. By cosine law:
R = √[a² + b² - 2abcos(3π/4)]
R = √[60² + 30² - 2*60*30*cos(3π/4)]
R = 83.94
Thus, a·b = 83.94
