Answer:

8.95

Step-by-step explanation:

You have the 8 already, so you just have to find the decimal of 19/20.

\frac{100}{20} = 5

So, \frac{1}{20} = \frac{100}{20}*\frac{1}{100} = 0.05\\19 * 0.05 = 0.95\\8 + 0.95 = 8.95

Evaluate the dot product of (2,4) and (1,2)
Aleksandr [31]

ANSWER

The dot product is 10.

EXPLANATION

The given vectors are (2,4) and (1,2).

If we have the vectors

u=(a,b) and v=(c,d)

Then the dot product of the two vectors is given by

u \bullet \: v = ac + bd

This implies that,

(2,4)  \bullet(1,2) = 2 \times 1 + 4 \times 2

This simplifies to;

(2,4)  \bullet(1,2) = 2  + 8 = 10

Find the missing side lengths, leave your answers as radical in simplest form. ( Please answer ASAP!)
alexira [117]

Answer:

9) a = 8, b = 4√2

10) x = 7√2, y = 7

11) x = 5√2, y = 5

12) a = 10, b = 5√2

Step-by-step explanation:

You can notice all these triangles are special as 45° - 45° - 90° triangles. In 45° - 45° - 90° triangles, the hypotenuse is √2 times the sides. We can set up these equations and solve:

9)

a = 4√2 * √2

a = 8

Since the triangle is isosceles, the legs are the same length, so:

b = 4√2

10)

x = 7 * √2

x = 7√2

Since the triangle is isosceles, the legs are the same length, so:

y = 7

11)

x = 5 * √2

x = 5√2

Since the triangle is isosceles, the legs are the same length, so:

y = 5

12)

a = 5√2 * √2

a = 10

Since the triangle is isosceles, the legs are the same length, so:

b = 5√2
