Answer:
A
Step-by-step explanation:
This is because 6f+f is just 7f.
f f f f f f+f = fffffff
Soooo, ONLY A gives us 7f when added together again.
f+5f+f=7f.
f+ f f f f f +f = fffffff
First find the domain(the set of all first coordinates in a function) by finding where the equation(a mathematical statement that says two expressions have the same value; any number sentence with an = sign) is defined.
After that you should know what to do. I don't know how to work this problem cuz i'm barely in 9 grade. But somehow, I know this.
(−∞,∞)
{x|x∈R}
If this helped, please let me know and give me brainliest, please!!
If this is incorrect, please let me know so I can fix it!
Answer:
50 square units
Step-by-step explanation:
Using the formula provided, , substituting the height (5), b1 (8) and b2 (12), we can solve for the formula.
Hope this helped!
Answer:
T3 = 30
Step-by-step explanation:
9x + 3y - 6z = 18. 6. 3x-5y+10z= 15.
10x + 4y+5z = 20
Answer: 85°
Step-by-step explanation:
Trig functions are remembered by
SOD CAD TOA,
sin = opposite / distance, cos = adjacent / distance, and tan = opposite / adjacent.
Here we have the adjacent side = 100, opposite side = 1058. The tower would fall over if it weren't vertical, and we assume the area is flat and level. So tangent of the answer is 10.58.
We need the angle whose tangent is 10.58.
On Android calculator you swipe left to get the trig functions, tap INV, if RAD is showing tap it to change it to DEG, and tap tan⁻¹. Swipe right and you see tan⁻¹(. Enter 10.58 and the result shows 84.6005606. If it shows 1.47655833 tap the RAD in upper left to change to DEG.
