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 th

Iteru [2.4K]

Answer:

8.90 seconds

Step-by-step explanation:

When the rocket hits the ground, its height ( y ) will be zero. This means we can write the equation as:

0 = -16x²+129x+119

So we need to solve that equation:

a = -16

b = 129

c = 119

x = $\frac{-b\frac{+}{-}\sqrt{b^2-4ac} }{2a}$

x₁ = -0.84

x₂ = 8.90

We discard x₁, as it is negative.

So the answer is x₂, 8.90 seconds.

7 × (–3) × (–2)2 = ?

kiruha [24]

$\huge\text{Hey there!}$

$\huge\text{7*(-3) * (-2)(2) = ?}$

$\huge\text{7 * (-3) = -21}$

$\huge\text{-21 * (-2)2 = ?}$

$\huge\text{-21 * -2 = 42}$

$\huge\text{42(2) = ?}$

$\huge\text{42 * 2 = 42 + 42 = 84}$

$\boxed{\boxed{\huge\text{Answer: 84}}}\huge\checkmark$

A rectangular field has an area 28800 sq meter. Its length is twice as long as its width. What is the length of its sides?

mina [271]

W= width L= length = 2W

Area of Rectangle= Length * Widthsubstitute the area and the value of L in the formula
28,800 m^2= 2W * W
28,800= 2W^2divide both sides by 2 in an effort to isolate the variable w
14,400= W^2take the square root of both sides
√14,400= W^2
we want the negative and positive root of the radicand (the number under the radical symbol - 14,400 in this case)
120= w OR -120= w

LENGTHL= 2W= 2(120)= 240 meters

ANSWER: The side lengths are W= 120 m; L= 240 m. Even though W= -120 too, it is not a valid solution in this case since a field cannot have a negative value.

Hope this helps! :)

Select the recursive and explicit formula for the Arnold family 2 answers

MariettaO [177]

Answer: The first and last options are correct

Explanation:

The recursive formula is written in terms of the previous term of the sequence. From the information given,

the Arnold's are going to save a nickel on the first day of the month and double the amount each day of the month. Thus, the recursive formula would be

$A(n)\text{ = a}_{n\text{ - 1}}\text{ }\times\text{ 2}$

where

an - 1 defines a previous term

To write the explicit formula, we would apply the formula for finding the nth term of an arithmetic sequence which is expressed as

An = ar^(n - 1)

where

a is the first term of the sequence

n is the number of terms

r is the common ratio between consecutive terms

Thus,

r = 2 because the amount is doubling each day

n = number of days

a = value of 1 nickel = $0.05

By substituting these values into the formula,

the explicit formula is

A(n) = 0.05(2)^n - 1
