Estimate the square root of 5 to the nearest tenth
Answer:
Step-by-step explanation:
It's about +- 2.2. It equals 2.236067977 but can be rounded to 2.2. When you square root, the answer could be positive or negative.
The square root of 5 to the nearest tenth is 2.2.
We have to find out the square root of 5 that should be the nearest tenth.
So, the following procedure should be followed:
[tex]= \sqrt{5}\\\\= 2.2360679[/tex]
= 2.2
Therefore we can conclude that the square root of 5 to the nearest tenth is 2.2.

Can someone help me find the value of X please?
Answer:
x = -4
Step-by-step explanation:
A circle is 360 degrees.
Anyway, first add 85 + 35 + 115 and you will get 235.
Now subtract 235 from 360.
360 - 235 = 125 degrees
Now to find x, do
-32x - 3 = 125
-32x = 128
-32x/-32 = 128/-32
x = -4

1. Determine f -1 (x) for each of the given functions
f (x) =2x-3
2. Determine f -1 (x) for each of the given functions
f (x) = x over x+2
Step-by-step explanation:
1) f(x) =2x -3
y=2x - 3
x= 2y -3
2y =x + 3
y = x+3 over 2
f(x)^-1 = x+3 over 2
2) f(x) = x /x+2
y= x / x+2
y / y+2 = x
y = (y+2)x
y= xy +2x
y -xy = 2x
y( -x +1) = 2x
y= 2x over -x + 1
f(x)^1 = 2x over -x + 1

How do you work this problem? 10x2 +25x
Answer:
x=-5/2,0
Step-by-step explanation:
It is solved by first factorizing it
10x²+25x=5x(2x+5)=0
Finding the zeros
5x=0x=0/5=0
2x+5=0
x=-5/2
Therefore x is -5/2 or 0

Use the figure below to find the length of the midsegment.
68
54
4x + 6
68
54
4x + 44
Answer:
38
Step-by-step explanation:
4x + 6 = ½(4x + 44) (midsegment theorem)
Multiply both sides by 2
2(4x + 6) = 4x + 44
8x + 12 = 4x + 44
Collect like terms
8x - 4x = -12 + 44
4x = 32
Divide both sides by 4
x = 8
Length of midsegment = 4x + 6
Plug in the value of x
Midsegment = 4(8) + 6
= 32 + 6
= 38
The Fruity Tooty company claims that the population proportion for each of its five flavors is exactly 20%. Jane counts 92 red candies in a 400-count sample.
what is the value of the z-test statistic? Answer choices are rounded to the hundredths place.
Answer:
86.96%
Step-by-step explanation:
s2 = a2 / n
a2 = 4.34782608696 if just 1/1 flavour 400/400 was the case.
We are asked to account for 5 flavours 4.34782608696/5
Z test was 0.86956521739 for red candies
s2 = a2/n
a2 = 0.86956521739/1
s2 = 0.86956521739/1
s2 = 0.87 hundredth place
Percentage 0.86956521739 x 100 = 86.96% to 100th place
Expand and simplify
2(4x + 3) + 4(3x - 1)
[tex]2(4x + 3) + 4(3x - 1)[/tex]
[tex] = (8x + 6) + (12x - 4)[/tex]
[tex] = 8x + 6 + 12x - 4[/tex]
[tex] = (8x + 12x) + (6 - 4)[/tex]
[tex] = 20x + 2[/tex]
Answer:
8x+6+12x-4= 0
20x+2= 0
20x=-2
20x/20= -2/20
x= -1/10

Solve the system of equations. − 3 x + 2 y = 56 − 5 x − 2 y = 24 −3x+2y=56 −5x−2y=24
Step-by-step explanation:
-3x + 2y = 56
+ (-5x - 2y = 24)
=> -8x = 80, x = -10.
Therefore -3(-10) + 2y = 56, 30 + 2y = 56, y = 13.
Hence x = -10 and y = 13.
Answer:
x = -10 and y = 13.
