Answer:
(90)(7) ⇒ the error was multiplying 90 and 7.
Step-by-step explanation:
12(597) = 12(500 + 90 + 7)
= 12(500) + (90)(7)
= 6000 + 630
= 6,630
The part in bold shows where the error is. It was not correct to multiply 90 and 7.
The process was to proceed as follows:
12(597) = 12(500 + 90 + 7)
= 12(500) + 12(90) + 12(7)
= 6000 + 1080 + 84
= 7,164
Answer:
Step-by-step explanation:
First, begin by multiplying by its reciprocal.
To do this, flip the fraction upside-down.
The resulting equation looks like this:
Cancel out the two 27's and you are left with , which you can simplify to q.
Next, multiply -3 by . Remember, what you do on one side, you must do on the other.
Your equation should look like this:
The final answer is .
Have a nice day!
Answer:
Q1
- cos 59° = x/16
- x = 16 cos 59°
- x = 8.24
Q2
BC is given 23 mi
<u>Maybe AB is needed</u>
- AB = √34² + 23² = 41 (rounded)
Q3
- BC² = AB² - AC²
- BC = √(37² - 12²) = 35
Q4
Let the angle is x
- cos x = 19/20
- x = arccos (19/20)
- x = 18.2° (rounded)
Q5
See attached
Added point D and segments AD and DC to help with calculation
- BC² = BD² + DC² = (AB + AD)² + DC²
<u>Find the length of added red segments</u>
- AD = AC cos 65° = 14 cos 65° = 5.9
- DC = AC sin 65° = 14 sin 65° = 12.7
<u>Now we can find the value of BC</u>
- BC² = (19 + 5.9)² + 12.7²
- BC = √781.3
- BC = 28.0 yd
<em>All calculations are rounded</em>
Answer:
Thus, the graph of the function is given below.
Step-by-step explanation:
We are given the ph of a particular solution as , where x represents the concentration of hydrogen ions in the solution.
Since, the function is given by,
So, we see that,
The domain of the function is {x | x≥2 } as logarithm function is not defined at zero.
Moreover, we see that,
As , the function
Thus, the graph of the function is given below.
