Answer:
T and F
Step-by-step explanation:
Hi! Maybe I am reading it wrong, but only 2 statements are given. The answer to these statements are true and false.
"A square root of 16 is 4."
4 squared, or 4 * 4 is equal to 16, and therefore this is true.
"The only square root of 9 is -3."
This is false. 9 has 2 square roots: 3 and -3.
3 * 3 = 9, and so does (-3) * (-3).
So we have T and F, which eliminates the second, third, and fourth choices, which means even without a last statement, A is your correct answer.
Hope I helped! :)
Answer:
commutative property
Step-by-step explanation:
Answer:
When we have a number like:
1.0x10^n
To rewrite this in standard form, we need to:
if n is positive, we move the decimal point n times to the right, adding zeros when necessary.
1.0x10^3
n = 3. then we add 3 zeros between the one and the decimal point, this is:
1.0x10^3 = 1000
if n< 0, then we move the decimal point n times to the left.
If we had:
1.0x10^-3
We move the decimal point 3 times to the left, adding zeros as this is needed.
1.0x10^-3 = 0.001
if n = 0, we have:
1.0x10^0 = 1.0
Now let's rewrite all the given numbers:
A) 3.4x10^-1 = 0.34
B) 1.36x10^6 = 1360000
C) 7.9x10^0 = 7.9
D) 2.4x10^5 = 240000
E) 5.21x10^-3 = 0.00521
F) 4.3x10^-2 = 0.043
Answer:
X= 7
Step-by-step explanation:
Well first combine like terms
27x-9=180
Isolate from the variable
27x=189
x=7
The final answer is 7
Given function is
At t= 79.5 degree.
So we can place t= 79.5 in given equation
=
=
=
So elevation equal to 625 meter at t = 79.5 degree.
