#4 Where is 44 on the number line?
A) At 22.
C) Between 6 and 7, but closer to 6.
B) Between 6 and 7, but closer to 7
D) Between 7 and 8, but closer to 7.

Answers

Answer:

B), Between 6 and 7, but closer to 7

Step-by-step explanation:

The square root of 44 is around 6.6, so closer to 7

You can prove this by multiplying 6.6 by itself

6.6 x 6.6 = 43.56

Element X is a radioactive isotope such that every 20 years, its mass
decreases by half. Given that the initial mass of a sample of Element X is 410
grams, how long would it be until the mass of the sample reached 270 grams,
to the nearest tenth of a year?

Answers

Answer:

12.1

Step-by-step explanation:

y=a(1/2)^t/h

270=410(1/2)^t/20

Divide both sides by 410

0.6585365854 = (1/2)^t/20

Log Both sides

Log(0.6585365854) / Log(1/2)

.6026645024= t/20

20 x .6026645024 = t

12.05329005 to the nearest tenth is 12.1 = t

Answer:

40.9

Step-by-step explanation:

Perimeter = 8 + 10 + 10 + 4 + 8.9

=> 20 + 4 + 8.9 + 8

=> 32 + 8.9

=> 40.9

This is already in the nearest tenth, so the answer = 40.9

which of the following equations represents the graph?
A. y = 3/4x - 3

B. y = 3/4x + 4

C. y = 4/3x - 3

D. y = 4/3x + 4

Answers

Answer is d. y=4/3+4

Answer:

D) 4/3 x + 4

Step-by-step explanation:

The y-intercept is at point (0, 4) and the x--intercept is at point (-3, 0).

The equation for every straight line is y = mx + b. y is y, m is the slope, x is x, and b is the y value in the y-intercept

Now we will use the formula for slope, which is rise/run or more understandable , the change in y/change in x.

y2 - y1/x2 -x1

0 - 4/-3 - 0

-4/-3 = 4/3

Remember when I said the y-intercept was (0, 4) and b was the value of the y in the y-intercept? 4 is the value of y in the y-intercept.

The answer is 4/3x + 4.

which equation represents the line that passes through points (5, 4) and (-5, 0)

Answers

Find slope: (y2-y1)/(x2-x1)
(0-4)/(-5-5) = -4/-10 = 2/5
Y = 2/5x + b
Plug in one point
4 = 2/5(5) + b, b = 2
Solution: y = 2/5x + 2

The equation should be [tex]y = 2\div 5x + 2[/tex]

Given that,

The points are (5, 4) and (-5, 0)

Based on the above information, the calculation is as follows:

here we need to find the slope.

[tex]= (y_2-y_1)\div (x_2-x_1)\\\\= (0-4)\div (-5-5) \\\\= -4\div -10 \\\\= 2\div 5\\\\Y = 2\div 5x + b[/tex]

Now  

Put in one point

[tex]4 = 2\div 5(5) + b, b = 2[/tex]

So,

[tex]y = 2\div 5x + 2[/tex]
