The expression -4.9t^2+50t + 2 represents the height, in meters, of a toy rocket t seconds after launch. The initial height of t

Kamila [148]

We have that

H(t)=-4.9t²<span>+50t + 2

we know that
</span><span>The initial height of the rocket, in meters is for t=0 sec
fot t=0
H(t)=</span>-4.9*0²+50*0 + 2------> H(t)=2 m

the answer is
The initial height of the rocket is 2 m

Do the law of order and the law of grouping apply to subtraction?

emmasim [6.3K]

Since we know that law of order states that sum or product of any two specific numbers will be same irrespective to their order. $a+b=b+a$ and $a*b=b*a$ .

Law of order is only applicable for addition and multiplication. It is not applicable to subtraction and division. Let us see it by an example.

$50-25\neq25-50$

$25\neq-25$

Law of grouping states that it does not matter how to order a group of numbers while adding or multiplying. $a+(b+c)=(a+b)+c$ and $a*(b*c)=(a*b)*c$ .

Law of grouping is not applicable to subtraction and division. Let us see it by an example.

$15-(5-3)\neq(15-5)-3$

$15-(2)\neq(10)-3$

$13\neq7$

Therefore, we can see that law of order and law of grouping is not applicable to subtraction.

What is the value of n in this equation: 2↑2 * 2↑n = (2↑4)↑3

Cloud [144]

Answer:

The value of n in the given equation is; n = 10

Step-by-step explanation:

Exponent for a natural power b is defined as iterated multiplication, which Knuth denoted by a single up-arrow:

a↑b = $a^b$ ......[1]

Given the expression: 2↑2 * 2↑n = (2↑4)↑3

Using [1] in the given expression is;

$(2^2) \cdot 2^n = (2^4)^3$

Using $a^n \cdot a^m = a^{n+m}$ and $(a^n)^m = a^{nm}$

we have;

$2^{2+n} = 2^{12}$

2 + n = 12 [ Using $a^m = a^n$ ⇒ m =n ]

Subtract 2 to both sides of an equation:

2 + n - 2 = 12 -2

Simplify:

n = 10

Therefore, the value of n is, 10

Find the missing fraction. <br> 1/2 + ____ =7/8

docker41 [41]

Answer:

3/8

Step-by-step explanation:

Let the missing fraction be x

So, 1/2+x =7/8

To find x, we take 1/2 to the rhs and 1/2 turns to -1/2

x = 7/8-(1/2)

Taking LCM as 8...

We can convert 1/2 to 4/8

Therefore,

x = 7/8 - 4/8

= (7-4)/8

=3/8

Hope this is helpful
