Answer:
7<em><u>f</u></em>
Step-by-step explanation:
You move 7 to the left of <em>f. </em>
This makes the exact value of <em>f</em>(7), 7<em>f</em>.
Answer:
5.35
Step-by-step explanation:
Answer:
f(5.9)= 15.7
Step-by-step explanation:
f(x) = 3x -2
f(5.9) = 3(5.9) -2
f(5.9) = 17.7 -2
f(5.9) = 15.7
Word Explination
If the (x) in f(x) is replaced by another variable (in this case, a number) any other x seen in the equation is replaced by that variable. For this question, the x in f(x) is replaced by 5.9. And so any other x in this equation needs to be replaced by 5.9 as well. From there on out, you solve.
Answer:
In this case, you can use the concept of cosine to calculate y, and things are even easier when you have one of the special angles which is a 45° angle.
So we know that: cos45° = √2/2
This fact will always be true. In our case, we have:
cos45° = 7/y
Therefore, we have the equation:
7/y = √2/2
⇔ 14 = y√2
⇔ y = 14/√2
⇔ y = √196/√2 = √(196/2) = √98 = 7√2
So y is equal to 7√2
The value of 0-((5)(-1)+(5)(-2)+(5)(-3)+(5)(-4)) is -40
<h3>What are integers?</h3>
An integer is a whole number (not a fractional number) that can be positive, negative, or zero.
Given:
0-((5)(-1)+(5)(-2)+(5)(-3)+(5)(-4))
= 0+5-10-15-20
=5-25-20
= -40
Hence, value of 0-((5)(-1)+(5)(-2)+(5)(-3)+(5)(-4)) is 40.
