Answer:
it is B
Step-by-step explanation:
i have taken the test
Answer:
B
Step-by-step explanation:
Given
f(x) = 3(x + 1)(x - 7) ← expand the factors using FOIL
= 3(x² - 6x - 7) ← distribute the parenthesis
= 3x² - 18x - 21 → B
They are already both positive numbers, so the absolute value of 2 is 2, and the absolute value of 1/3 is 1/3.
Answer:
M-T={even numbers}
Step-by-step explanation:
We are given that
={x:2
,x is an integer}
M={even numbers}
P={Prime numbers}
T={odd numbers}
We have to find M-T
We know that
Using the formula
Then, we get
M-T={even numbers}-
M-T={even numbers}
Ramesh is not correct because as the exponents decrease, the previous value is divided by 7
.
<u>Explanation:</u>
An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.
Exponents are superscript numerals that let you know how many times you should multiply a number by itself. Some real world applications include understanding scientific scales like the pH scale or the Richter scale, using scientific notation to write very large or very small numbers and taking measurements.
