(Find the value of x in degrees)
Answers
Answer:
x = 25 and x = 47
Step-by-step explanation:
(9)
The given angles are vertical and congruent , then
2x + 10 = 60 ( subtract 10 from both sides )
2x = 50 ( divide both sides by 2 )
x = 25
(10)
The given angles are vertical and congruent , then
2x + 6 = 100 ( subtract 6 from both sides )
2x = 94 ( divide both sides by 2 )
x = 47

Answer:
1. 6.13
2. 0.57
Step-by-step explanation:
1. 7 x 4 = 28
28 / 8 = 3.5
3.5 x 7 = 24.5 / 4 = 6.13
s = 6.13
2. 2 x 3 = 6
6 / 7 = 0.85
0.85 x 2 = 1.71
1.71 / 3 = 0.57
s = 0.57

Step-by-step explanation:
1)
Let's use the Pythagorean Theorem:
[tex]X^2 + 13^2 = 21^2[/tex]
[tex]X^2 + 169 = 441[/tex]
[tex]X^2 = 272[/tex]
[tex]X= \sqrt{272} = 4\sqrt{17} = 16.5[/tex]

Let's use the Pythagorean Theorem:
[tex]16^2 + 28^2 = x^2[/tex]
[tex]x^2 = 1040[/tex]
[tex]x = \sqrt{1040} = 4\sqrt{65} = 32.2[/tex]

Find the maximum value of y = -x^2 + 6x + 5
Answers
Answer:
D
Step-by-step explanation:
The maximum value is the y- coordinate of the vertex
Given a quadratic in standard form , y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = - x² + 6x + 5 ← is in standard form
with a = - 1 and b = 6 , then x- coordinate of vertex is
x = - [tex]\frac{6}{-2}[/tex] = 3
Substitute x = 3 into the function for y- coordinate of vertex
y = - 3² + 6(3) + 5 = - 9 + 18 + 5 = 14
maximum value is 14 → D
