Answer:

6.2

Step-by-step explanation:

P - 4.2 =2

we have to no separate the variables and constants

so , when we move 4.2 to the other side ( other side of 2) it will be something like this

p = 2+4.2

as you can wee when we moved 4.2 to the other side the operation changed from ,minuus to plus sign .

now just do what it says

formula :

=p-4.2=2

=p = 2+4.2

= 2+ 4.2= 6.2

so,

p=6.2

write the formula , I think no need to write explanation

Answer:

400 ft

Step-by-step explanation:

h(t)= -16t^2 + 160t

The vertex is found at

h = -b/2a where b is the coefficient of t and a is the coefficient of t^2

= -160/(2*-16)

-160/-32

The time where the maximum occurs is at t=5

To find the maximum substitute into the function

h(5) = -16 (5)^2 +160*5

= -16*25 +800

=-400+800

= 400

The maximum height is 400 ft

Which expressions are equivalent to R16? Check all that apply.

Ilya [14]

Option C: $(6^{-4})^{-4}$

Option D: $(6^{-2})^{-8}$

Option F: $(6^8)^2$

Solution:

Given expression: $6^{16}$

To find which expression is equivalent to the given expression.

Let us solve this using exponent rule: $\left(a^{b}\right)^{c}=a^{b c}$

Option A: $(6^{0})^{16}$

$(6^{0})^{16}=6^{0 \times 16}= 6^0$

It is not equivalent expression.

Option B: $(6^8)^8$

$(6^{8})^{8}=6^{8 \times 8}= 6^{64}$

It is not equivalent expression.

Option C: $(6^{-4})^{-4}$

$(6^{-4})^{-4}=6^{(-4 )\times (-4)}= 6^{16}$

It is equivalent expression for the given expression.

Option D: $(6^{-2})^{-8}$

$(6^{-2})^{-8}=6^{(-2) \times (-8)}= 6^{16}$

It is equivalent expression for the given expression.

Option E: $(6^{-1})^{16}$

$(6^{-1})^{16}=6^{(-1) \times 16}= 6^{-16}$

It is not equivalent expression.

Option F: $(6^8)^2$

$(6^{8})^{2}=6^{8 \times 2}= 6^{16}$

It is equivalent expression for the given expression.

Hence $(6^{-4})^{-4}, \ (6^{-2})^{-8}, \ (6^8)^2$ are the equivalent expressions.

Option C, Option D and Option F are correct answers.

Can someone solve this for me please <br><br>its algebra <br><br>1/4(12 +x ) +1/2( x− 6)

Pavel [41]

Answer:

x=4

Step-by-step explanation:

what i did is try to make some whole number and the minimum i got was 4.

1/4 = 0.25 so then do 12+4=16. then do 16*0.25=4. now do 4-6=(-2) then 1/2=0.5. now do 0.5* -2= -1. now do 4-1=3. now when there's no answer x can equal anything
