HACTEHA [7]3 years ago

Ok so how you round is from the tens place in 5.82 the tens place is equal to 80 and you would round to 6 and 1.76 would also be rounded to 2 because is more than 5.so the answer will be 6-2 and that is 4.I hope this helps♡♡♡

For f (x) - 4x +1 and g(x) = ? -5, find (fºg)(4).
Alona [7]

(f\circ g)(x)=f(g(x))=4(x^2-5)+1=4x^2-19

(f\circ g)(4)=4\cdot4^2-19=64-19=\boxed{45}

Hope this helps.

If line VX is the bisector of angle V, find the perimeter of triangle VUW .
umka21 [38]
Since VX is the bisector of angle V and < VXU is a right angle then  UX is congruent to XW and triangle VUW is isosceles with VU = VW.

3z - 4 = x + 6
2z = 10
z = 5

so UW = 3(5) - 4 + 5 + 6  = 22
and VW = 5(5) - 1 = 24

VU = VW = 24 

perimeter = 2(24) + 22 =  70

I am a number greater than 40,000 and less than 60,000. My ones digit and tens digit are the same. My ten-thousands digit is 1 l
jarptica [38.1K]
I am a number greater than 40,000 and less than 60,000:

40,000 < n < 60,000

This means that:

n = 10,000n₁ + 1,000n₂ + 100n₃ + 11n₄

And also:

4 ≤ n₁ < 6

0 ≤ n₂ ≤ 9

0 ≤ n₃ ≤ 9

0 ≤ n₄ ≤ 9

My ten thousands digit is 1 less than 3 times the sum of my ones digit and tens digit:

n₁ = 3*2n₄ - 1

n₁ = 6n₄ - 1

This means that:

n = 10,000*(6n₄-1) + 1,000n₂ + 100n₃ + 11n₄

n = 60,000n₄ - 10,000 + 1,000n₂ + 100n₃ + 11n₄

n = 60,011n₄ - 10,000 + 1,000n₂ + 100n₃

<span>My thousands digit is half my hundreds digit, and the sum of those two digits is 9:

n</span>₂ = 1/2 * n₃
<span>
n</span>₂ + n₃ = 9
<span>
Therefore:

n</span>₂ = 9 - n₃
<span>
Therefore:

9 - n</span>₃ = 1/2 * n₃
<span>
9 = 1/2 * n</span>₃ + n₃
<span>
9 = 1.5 * n</span>₃
<span>
Therefore:

n</span>₃ = 6
<span>
If n</span>₃=6, n₂=3.
<span>
This means that:

</span>n = 60,011n₄ - 10,000 + 1,000*3 + 100*6

n = 60,011n₄ - 10,000 + 3,000 + 600

n = 60,011n₄ - 6,400

Therefore:

0<n₄<2, so n₄=1.

If n₄=1:

n = 60,011 - 6,400

n = 53,611

Answer:

53,611
