Answer:

F(5)=11

F(-3)=2

Step-by-step explanation:

F(x)
F(5)=?
x=5

5>2 so,

F(x)=4x-9 for x=5

F(5)=4*5-9=11

F(-3)=?
x=-3

-3 $\leq$ 2 so,

F(x)=-2x-4 for x=-3

F(-3)=-2*-3-4=2

Angles a and b are in the fourth quadrant. If sin a = -12/13 and cos b = 20/29 find tan (a+b)

valkas [14]

Answer:

tan (a+b) = 2.27 or (345/152)

Step-by-step explanation:

a and b are in the fourth quadrant

sin a = -12/13 tan a = - 12/5 = - 2.4

cos b = 20/29 tan b = - 21/20 =.1.05

tan (a+b) = (tan a + tan b) / (1 - tan a * tan b)

= (-2.4 + - 1.05) / ( 1 - (-2.4)*(-1.05))

= (-3.45) / (-1.52)

= 2.27

A grocer store a, Five cans of baked beans cause $3.45. A grocery store B 7 cans of baked beans cost $5.15. At grocery store C 4

maks197457 [2]

Answer:

$1.5

Step-by-step explanation:

Given:

At grocery store A, 5 cans of baked beans cost $3.45.

At grocery store C, 4 cans of baked beans cost $2.46.

To find:

How much money would you save if you bought 20 cans of beans at grocery store C that if you brought 20 baked beans from grocery store A ?

Solution:

At grocery store A, cost of 5 cans of baked beans = $3.45

At grocery store A, cost of 1 cans of baked beans = $\frac{3.45}{5}$

At grocery store A, cost of 20 cans of baked beans = $\frac{3.45}{5} \times20=\frac{69}{5} = 13.8$

At grocery store C, cost of 4 cans of baked beans = $2.46.

At grocery store C, cost of 1 cans of baked beans = $\frac{2.46}{4}$

At grocery store C, cost of 20 cans of baked beans = $\frac{2.46}{4} \times20 = \frac{49.2}{4} = 12.3$

Saving will be $13.8 - $12.3 = $1.5

Therefore, you will save $1.5 if you bought 20 cans of beans at grocery store C that if you brought 20 baked beans from grocery store A.
