A rocket is launched from a tower. The height of the rocket, y in feet, is
related to the time after launch, x in seconds, by the given equation. Using
this equation, find the maximum height reached by the rocket, to the nearest
tenth of a foot.
y = -16x2 + 212x + 139

Answers

Answer:

y = 841.25 feet

Step-by-step explanation:

Given that,

The height of the rocket, y in feet, is  related to the time after launch, x in seconds, by the given equation as follows:

[tex]y = -16x^2 + 212x + 139[/tex] ....(1)

We need to find the maximum height reached by the rocket.

For maximum height, put dy/dx = 0

So,

[tex]\dfrac{d(-16x^2 + 212x + 139)}{dx}=0\\\\-32x+212=0\\\\x=\dfrac{212}{32}\\\\x=6.625\ s[/tex]

Pu x = 6.625 in equation (1).

[tex]y = -16(6.625)^2 + 212(6.625) + 139\\\\y=841.25\ feet[/tex]

So, the maximum height reached by the rocket is equal to 841.25 feet.

A bat was flying for four and a half hours at a constant speed of ten kilometers per hour. How far did the bat travel in meters?

Answers

Answer:

45000 m

Step-by-step explanation:

Speed = distance / time

10 km/h = distance / 4.5 hours

Pregunta completa:

Un albañil pone azulejos a una pared de 6 m de largo y 2,4 m de alto. Los azulejos son cuadrados de 30 cm de lado. ¿Cuants, cajas tendra que comprar si en una caja hay 25 azulejos? Con procedimiento.

Respuesta:

160 tejas

7 cajas

Explicación paso a paso:

Dimensión de la pared = 6 m por 2,4 m

Área de la pared = 6 m * 2,4 m

Área de la pared = 14,4 m²

Longitud lateral, s de teja cuadrada = 30 cm = 0,3 m

Área de la loseta cuadrada = s² = 0.3² = 0.09m²

Número de baldosas cuadradas necesarias:

14,4 m² ÷ 0,09 m²

= 160 fichas cuadradas

Si hay 25 fichas en una caja;

Número de cajas a comprar:

160/25

Answers

Answer:

x²+2x+3

Step-by-step explanation:

We are to simplify the expression;

5x³+10x²+15x/5x

Factor out 5x from the numerator

= 5x(x²+2x+3)/5x

5x will cancel out both at the top and bottom to have;

Find area of the figure. PLEASE HELP!

Answers

Answer:

69

Step-by-step explanation:

Answer:

69 m²

Step-by-step explanation:

The figure is composed of 2 right triangles

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

A of triangle on left is

A = [tex]\frac{1}{2}[/tex] × 9 × 10 = 45 m²

A of triangle on right is

A = [tex]\frac{1}{2}[/tex] × 8 × 6 = 24 m²

What value of b will make the equation a true statement? Explain how you arrived at your solution. (−34 + 43)+ b = 0

Answers

Answer:

b = -9

Step-by-step explanation:

Given the equation (−34 + 43)+ b = 0

We are to find the value of b

First solve for the value in parenthesis

(−34 + 43)+ b = 0

9+b = 0

Subtract 9  from both sides

9+b-9 = 0 - 9

b+0 = -9

b = -9

Hence the value of b will make the equation a true statement is -9
