Answer:
Step-by-step explanation:
These are mostly calculator problems. The only trick is the last one. Your calculator will have either a y^x button or ^ button. They both do the same thing.
So for the last one, you must do it as
64 y/x (1÷6)= and you will get 2. Perhaps all of them should be done that way.
If your calculator uses ^ then you would do it
64^(1÷6)= which is the same thing.

This problem is very easy when you follow the pemdas rule.
As always, you do multiplications before additions and subtractions, so, you do 9x5 and 7x8 first, then, you can add them together.
<span>9×5+101+7×8=?
(9x5)+101+(7x8)=?
45+101+56=?
= 202</span>
Answer:
, and , .
Step-by-step explanation:
A polynomial is an algebraic function of the form:
(1)
Where:
- i-th Coefficient.
- i-th Power.
- Grade of the polynomial.
- Dependent variable.
Mathematically speaking, polynomials are unbounded functions, and from graphic we notice that polynomial is of order 3 due to the fact that function pass through the x axis three times, where each point is a root of the polynomial.
Then, we may conclude that:
(i)
(ii)
Then, the right answer is: , and , .
Answer: 14x^2 - 84x - 7
====================================================
Explanation:
The like terms 6x^2 and 8x^2 combine to 14x^2
The like terms -8x and -76x combine to -84x
Nothing pairs with the -7, so its stays as is.
Standard form is where we list the terms in decreasing exponent order. We can think of -84x as -84x^1 and the -7 as -7x^0. So 14x^2 - 84x - 7 would be the same as 14x^2 - 84x^1 - 7x^0. The exponents count down: 2,1,0.
The final answer is a trinomial since it has three terms. It is also a quadratic because the degree (highest exponent) is 2.
Answer:
m∠8 = 30°
Step-by-step explanation:
Since line AB is parallel to line CD, and m∠4 = 30°, therefore:
m∠4 and m∠8 are corresponding angles.corewslinding angles are congruent.
Therefore, this means that their measure would be equal to each other, since they are congruent.
Thus:
m∠8 = 30°
