Answer:
b = -9
Step-by-step explanation:
Axis of symmetry of a parabola = -b / 2a.
Where y = ax² + bx + c.
Given f(x) = 3x^2 + bx + 4,
a = 3, and c = 4.
If the axis of symmetry is 3/2, than b can be found by substitution and algebra.
[ x = -b / 2a ] → [ 3 / 2 = -b / 2a ] →
[ 3 / 2 = -b / 2 (3) ] → [ 3 / 2 = -b / 6 ] →
[ 3 / 2 × 6 = -b / 6 × 6 ] → [ 18 / 2 = -b ] →
[ 9 = -b ] → [ -b = 9 ] → [ (-)(-b) = (-)(9) ] →
b = -9

Question: pentagon STUVW is similar to S' T' U' V' W'. angle U=56 degrees, angle U' = 3x-16, and Angle T'=x+46. ST=57, UV=63, S' T'=19 and U' V' =y+4
a. Find x
b. find angle T'
c. Find y
you have to do, a, b, and c
Answer:
Similarity doesn't changes angle measures
∠U = 56°, ∠U' = 3x - 16∠U = ∠U'a) 3x - 16 = 56 ⇒ 3x = 72 ⇒ x = 24°
b) ∠T = x + 46 = 24 + 46 = 70°
c) Scale factor:
k = S'T'/ST = 19/57 = 1/3Find y using known sides and scale factor:
U'V'/UV = 1/3(y + 4)/63 = 1/3y + 4 = 21y = 21 - 4y = 17Help with graph pleaseeee
HELP WILL GIVE YOU Brainiest!!!
Answer:
Step-by-step explanation:
So there we have it, <A=135° and <B=45°. This should check when you add them together ("<A and <B are supplementary which means that together their angles equal 180°"). Does 135°+45=180°? YES!
I Really hope it helps
Using the digits 1, 3, 5, 7 at most once, you can make many three-digit numbers. What is the maximum possible sum of two such distinct numbers?
Answer:
1504
Step-by-step explanation:
Given the digits :
1, 3, 5, 7
The maximum possible sum of two distinct three digit numbers formed from the digits above will be the sum of the the two hight possible three digit numbers that can be formed.
Highest three digit number = 753
Next highest = 751
The sum of these two. Values gives :
753 + 751 = 1504

The difference between two numbers is 3. The sum of the same tow numbers is 13. What is the
product of the two numbers?
Answer: 40
Step-by-step explanation:
Let the two numbers be a and b.
Therefore,
a - b = 3 ....... i
a + b = 13 ....... ii
From equation I, a = 3 + b
Put a = 3+b into equation ii
a + b = 13
3 + b + b = 13
3 + 2b = 13
2b = 13 - 3
2b = 10
b = 10/2
b = 5
Since a = 3 + b
a = 3 + 5
a = 8
The product of the numbers will be:
= 8 × 5
= 40
Miguel compró 253 Kilos de pescado para venderlo en su negocio, si decide vender cada kilo de pescado en Bs 1.900.000. Entonces, ¿Cuánto dinero recaudó en total por la venta del pescado?
Answer:
Miguel recaudó Bs 480.700.000 por la venta del pescado.
Step-by-step explanation:
Con la información proporcionada puedes calcular el dinero que recaudó en total por la venta del pescado multiplicando el precio de venta de cada kilo de pescado por el número de kilos que Miguel compró:
Número de kilos comprados=253
Precio de venta por kilo=1.900.000
Total vendido=253*1.900.000
Total vendido=480.700.000
De acuerdo a esto, la respuesta es que Miguel recaudó Bs 480.700.000 por la venta del pescado.

En la tienda de don chuy vender tres cajas de colores de 36 piezas en $258,en cambio en la papeleria de la ciudad encontramos 5 piesas delos colores en$440
Responder:
Tienda de la ciudad
Explicación paso a paso:
Para obtener el precio unitario por caja:
Importe pagado / número de cajas.
Para cajas de 3 colores:
$ 258/2 = $ 129
Para las cajas de color /:
$ 440/5 = $ 88
$ 88 <$ 129
Por lo tanto, las cajas de colores son más baratas en la tienda de la ciudad.

Answer:
3734.95
Step-by-step explanation:
Pi = 3.14 to find the radius of a circle we multiply the circumference and Pi. Then square it. So, 34.48x3.14 = 108.2672 then 108.2672² = 3734.94651 which rounds to 3734.95
The Hernandez family orders 3 large pizzas. They cut the pizzas so that each pizza has the same number of slices, giving them a total of 24 slices.
The Wilson family also orders several large pizzas from the same pizza restaurant. They also cut the pizzas so that all their pizzas have the same number of slices. For the Wilson family, the equation y = 10x represents the relationship, where x represents the number of pizzas and y represents the number of total slices.
Which statements best describe the pizzas bought by the Hernandez and Wilson families? Select two options.
For the Hernandez family, the equation y = 3x represents the relationship between the number of slices and number of pizzas, where x represents the number of pizzas and y represents the number of total slices.
For each family, a graph of the relationship between number of pizzas, x, and number of slices, y, goes through the point (0, 0) and is a straight line.
The Hernandez family’s slices are smaller than the Wilson family’s slices.
If the Wilson family ordered 3 large pizzas from the same restaurant as the Hernandez family, they would have more slices than the Hernandez family after each family cut their pizzas into slices.
The constant of proportionality is 10 for the Wilson family, but cannot be determined for the Hernandez family.
