Rewrite f(x) into vertex form by completing the square f(x)=−x2+8x+9
Answer:
vertex = ( 4 , 25 )
Step-by-step explanation:
given a parabola in standard form y = a x 2 + b x + c x ; a ≠ 0
then the x-coordinate of the vertex is
X vertex=-b/2a
y=-x2+8x+9 with a=-1 b=8 c=9
X vertex= -8/-2=4
substitute the value on the equation
Y vertex = -(4)squared+8(4)+9=25

Una mamá tiene el cuádruplo de la edad de su hijo, y dentro de 5 años, tendrá el triple de años que el. Indica que edad tienen ambos.
Answer:
The son age is 10 years
And, his mother age be 40 years
Step-by-step explanation:
Given that
The mother is four times the age of her son
And, in 5 years, she will be three times as old as him
We need to find out the ages of both
Here we assume that the age of her son be x
So the mother age be 4x
Now in 5 years, her mother would be 3 times as old as his son
So,
4x + 5 = 3(x + 5)
4x + 5 = 3x + 15
x = 10
The son age is 10 years
And, his mother age be 40 years

What is the value of x
Answer:
x = 36.03°
Step-by-step explanation:
We have to find: Angle A, also called "x
We are given: Side opposite to x and the hypotenuse of the triangle.
Trigonometric Ratio that would be used: Sin
=> Sin(x) = Opposite/Hypotenuse
=> Sin(x) = 10/17
=> x = Sin⁻¹(10/17)
=> x = 36.03 Degrees
Hope this helps!

Miko and her parents rent boats for the afternoon. Her parents rent a canoe and Miko rents a kayak. • It costs $20.49 to rent a canoe plus an additional $7.49 for each hour. • It costs $17.99 to rent a kayak plus an additional $5.99 for each hour. Miko and her parents rent one canoe and one kayak for the same amount of time, and their total cost for the rentals is $78.92. Write and solve an equation to determine the amount of time, in hours, that they rented the kayak and canoe.
Answer:
Kayak and Canoe rented for 3 hours
Step-by-step explanation:
Let the time for which they rent canoe & kayak = x hours
Total canoe cost = 20.49 + 7.49x , Total kayak cost = 17.99 + 5.99x
Given] Total canoe & kayak cost = 78.92
So, (20.49 + 7.49x) + (17.99 + 5.99x) = 78.92
20.49 + 17.99 + 7.49x + 5.99x = 78.92 ; 38.48 + 13.48x = 78.92
13.48x = 78.92 - 38.48 ; 13.48x = 40.44
x = 40.44 / 13.48 ; x = 3

66.49
[ ? ]cm
Enter
9514 1404 393
Answer:
9.2 cm
Step-by-step explanation:
The arc length is given by ...
s = rθ . . . . . where r is the radius, and θ is the central angle in radians
Here, we have ...
s = (7.9 cm)(66.4/180π) = 7.9·66.4·3.14/180 cm ≈ 9.2 cm
Arc length CD is about 9.2 cm.

Joãozinho de Gitana calculadora o número de 12750 Qual é o número que tempo para subtrair para obter como resultado o número 12250
Responder:
500
Explicação passo a passo:
O número a subtrair de 12.750 em outro para obter 12.250
Deixe o número = x
Isso é ; se x for subtraído de 12750; nós obtemos 12250
12750 - x = 12.250
Subtraia 12750 de ambos os lados
12750 - x - 12750 = 12.250 - 12750
-x = - 500
x = 500

PLEASE HELP ASAP Find the value of x.
Answer:
x = 9
Step-by-step explanation:
The secant- secant angle 4x° is half the difference of the intercepted arcs, that is
4x = [tex]\frac{1}{2}[/tex] (9x + 26 - 35 ) ← multiply both sides by 2 to clear the fraction
8x = 9x - 9 ( subtract 8x from both sides )
0 = x - 9 ( add 9 to both sides )
9 = x
