Answer:

2.9 units

Step-by-step explanation:

Here the leg lengths are x and 7.7 and the one given angle is 21 degrees.

Think:  which trig function incorporates both the length of the side opposite the 21 degree angle (x) and the vertical side (7.7)?  It's the tangent function:

tan Ф = opp / adj

To be clear:  the side adjacent (next to) the 21 degree angle is 7.7 units in length and the side opposite this angle is x.

Then we have tan 21 degrees = opp / adj = x / 7.7

and so 7.7(tan 21 degrees) = 7.7(03839) = 2.96 or (to one decimal place) 2.9

STALIN [3.7K]
Answer: chicken $8, duck $5

Explanation:

x - the cost of a chicken
y - the cost of a duck

he sold 50 chickens and 30 ducks for $550: 50x + 30y = 550
he sold 44 chickens and 36 ducks for $532: 44x + 36y = 532

50x + 30y = 550                divide by 10
44x + 36y = 550                 divide by 4
______________
50x/10 + 30y/10 = 550/10
44x/4 + 36y/4 = 532/4
______________
5x + 3y = 55                                    
Multiply by (-3)
11x + 9y = 133
______________
5x * (-3) + 3y * (-3) = 55 * (-3)
11x + 9y = 133
______________
-15x - 9y = -165
11x + 9y = 133
______________
Sum up:
-4x + 0y = -32
-4x = -32
x = -32/-4
x = 8

Since 5x + 3y = 55  and x = 8, then:
5 * 8 + 3y = 55
40 + 3y = 55
3y = 55 - 40
3y = 15
y = 15/3
y = 5

PLEASE HELP.
Harrizon [31]

ANSWER

The maximum y-value is 0.

EXPLANATION

The domain of the given absolute value function is (-∞, ∞) .

This means the function is defined for all real values of x.

The range of the function is (-∞, 0].

This can be rewritten as

y \leqslant 0

This means that, the highest y-value on the gray of this absolute value function is 0.

Hence the maximum y-value of the function is 0.
