Evaluate the expression -5-3+1

Mathematics

Answer:

-7

Step-by-step explanation:

The rule for subtraction, in this case it is -5-3, you change the subtraction sign to addition and use the opposite of the second number, making it -5+(-3) which is -8. Then, you add 1 to -8, and the rule for this specific expression is to take the absolute value of both -8 and 1, then subtract the two, making the expression as of now 8-1. Subtract them, and get 7, but you take the sign of whichever number had the greatest absolute value, which was -8, so now the answer is -7. That's how you get your answer

-5-3+1= -5+(-3)+1

-8+1= |-8|-|1|

8-1= -7 (because you take the sign with the greatest absolute value, which is -8.)

After the release of radioactive material into the atmosphere from a nuclear power plant in a country in 1982​, the hay in that
galina1969 [7]

Answer:

25.48 days

Step-by-step explanation:

For a radioactive substance, the Amount of the substance remaining A(t) is modeled by the equation

A(t)=A_0(\dfrac{1}{2})^{\dfrac{t}{t_{1/2}} }

where

A_0 =$Initial Amount$\\t_{1/2}=$Half-Life of the Substance$\\t=$Time elapsed$

In the given problem:

Half Life of the Radioactive Isotope = 8

Initial Amount, A_0=100%=1

A(t)=11% =0.11

Therefore substituting in the model above:

0.11=1(\dfrac{1}{2})^{\dfrac{t}{8} }\\0.11=0.5^{t/8}\\$Change to Logarithm form$\\Log_{0.5}0.11=\frac{t}{8}\\\frac{Log 0.11}{Log 0.5} =\frac{t}{8}\\3.1844=\frac{t}{8}\\t=8X3.1844=25.4752

The farmer need to wait for 25.48 days

consider the following equations: -x-y=1 y=x+3 if the two equations are graphed, at what point do the lines representing the two
Oksana_A [137]

Answer:

(-2, 1)

Step-by-step explanation:

consider the following equations: -x-y=1 y=x+3

For the lines to intersect, the  values must be the same

-x-y=1

x + y = -1

y = -x - 1

Equating the y values

-x - 1 = x+ 3

-x-x = 3 + 1

-2x = 4

x = 4/-2

x = -2

Substitute x = -2 into y = x+3

y = -2 + 3

y = 1

Hence the required coordinate is (-2, 1)
