Answer:
-10
Step-by-step explanation:
f(3) just means plug the 3 in replace of x
f(3) = -4(3)+2
f(3)= -12+2
f(3)=-10
y = 218.2. The lenght of side y by trigonometry is 218.2.
In order to solve this problem we are going to use the angles and sides of a right triangle and its relation by expressions that we call trigonometric ratios.
In the image we can see that the lenght of the opposite leg is 141 , we do not know the lenght of the adjacent leg y and the hypotenuse x. The key to solve this problem is to use trigonometric ratios and the equation tan θ = sin θ/cos θ = opposite leg/adyacent leg = 141/y
Clear for y for the equation tan θ = sin θ/cos θ = 141/y, we obtain:
y = arctan θ (141)
y = arctan (43°)(141) = 218.2
I’m still trying to get help to on the same problem
I believe it takes 1 3/5 hrs for them to finish the job together
The Mathematical statement which includes addition, subtraction and multiplication:
→4+8x(18+5)+18+(8x4x5)+0x(5+3)
= 4 + 8 × 18 + 8 × 5 + 18 +(32 × 5) + 0 × 5 + 0 × 3 → [ Using distributive property which is , a × (b +c)= a × b + a × c, and (p × q × r)= [ (p × q) × r]
= 4 + 144 + 40 + 18 + 160 + 0 + 0
= 148 + 58 + 160 → [ Using addition property of natural numbers, as you can add natural numbers in any order]
= 206 + 160
= 366
