Find the value of X
Answers
Answer:
should be 80, angle 50 is congruent on both sides to 50+50 equals 100. The triangle sum theorem says a triangle adds up to 180 degrees so we are left with 80, X=80 degrees
50 + 50 + x = 180
thus , x = 80
Identify The domain of the rational function, g(x)= 1/x+3
A (-∞, ∞)
B (-∞, 3)U(3, ∞)
C (-∞, -3]U[-3, ∞)
D (-∞, -3)U(-3, ∞)
Answers
Answer:
The domain is (-∞ , -3) ∪ (-3, ∞) ⇒ D
Step-by-step explanation:
The domain of the rational fraction is the values of x which make the fraction defined. That means the domain does not contain the values of x which make the denominator equal to 0.
∵ g(x) = [tex]\frac{1}{x+3}[/tex]
∴ The denominator = x + 3
→ Equate the denominator by 0
∵ x + 3 = 0
→ Subtract 3 from both sides
∴ x + 3 - 3 = 0 - 3
∴ x = -3
→ That means the domain can not have -3 because it makes the denominator
equal to 0
∴ The domain is all values of real numbers except x = -3
∴ The domain = {x : x ∈ R, x ≠ -3}
∴ The domain = (-∞ , -3) ∪ (-3, ∞)

Step-by-step explanation:
A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t2+48t+160 gives the height, t, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
Answers
Answer:
t = 5 s
Step-by-step explanation:
The function that gives the height in feet of the ball t seconds after it is thrown is :
[tex]h(t)=-16t^2+48t+160[/tex]
We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.
So,
[tex]-16t^2+48t+160=0[/tex]
We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.
t = -2 s is not possible.
Hence, the ball will hit the ground before 5 seconds.
5. What is the perimeter of a rectangle with a length of 9x - 4 and a width of 5x+2?
Answers
Answer:
14x-2
Step-by-step explanation:
In order to find the perimeter we need to add the length and width together. So adding 5x and 9x gives us 14x. -4+2=-2
The perimeter of a rectangle with a length of 9x - 4 and a width of 5x+2 is, 28x-4
What is the perimeter?Perimeter is a mathematical term, which means total outer boundary of a figure, we define it only for two dimensional figures.
Perimeter = Sum of length of the all the sides
Given that,
length of rectangle = 9x - 4
width of rectangle = 5x+2
As we know,
Perimeter = Sum of length of the all the sides
Perimeter = (9x - 4) + (5x+2) + (5x+2) + (9x - 4)
Perimeter = 28x-4
Hence, The perimeter is 28x-4

Anna made and sold x ceramic vases one week. Her profit, P, in dollars is calculated using the formula P = R - C . Where R represents her revenue and C represents her costs. If R = 25x - 0.5x ^ 2 C = 100 + 5x which expression represents her profit in dollars?
Answers
Answer:
-0.5x² + 20x + 100
Step-by-step explanation:
Given:
R = 25x - 0.5x²
C = 100 + 5x
P = R - C
Where,
P = profits
R = Revenue
C = Cost
which expression represents her profit in dollars?
P = R - C
R = 25x - 0.5x²
C = 100 + 5x
= 25x - 0.5x² -(-100 + 5x )
= 25x - 0.5x² + 100 - 5x
= -0.5x² + 20x + 100
The expression which represents her profit in dollars is -0.5x² + 20x + 100
