Answer:

The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation. ... This is because there is truly no solution—there are no values for x that will make the equation true

Serggg [28]

Answer:

$a=\sqrt{6},\:a=-\sqrt{6}$

Step-by-step explanation:

Given

b is a real number

$a^2=b$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$a^2=6$

$a=\sqrt{b},\:a=-\sqrt{b}$

Therefore,

$a=\sqrt{6},\:a=-\sqrt{6}$

IceJOKER [234]

Given that the function

$C(h)=\frac{2h^2+5h}{h^3+8}$

models the concentration of a medication in the bloodstream (as a percent), hours (h) after its injection into muscle tissue.

The number of hours it will take for the concentration of the injection to be less than 0.5% is given by:

$0.5\ \textgreater \ \frac{2h^2+5h}{h^3+8} \\ \\ \Rightarrow0.5(h^3+8)\ \textgreater \ 2h^2+5h \\ \\ \Rightarrow h^3+8\ \textgreater \ 4h^2+10h \\ \\ \Rightarrow h^3-4h^2-10h+8\ \textgreater \ 0 \\ \\ \Rightarrow h\ \textgreater \ 5.54$

Given that the first injection was given at 8:00 am, the time the next injection should be given is 2 pm.

Square A is a scaled version of square B. The dimensions of square A are three times the dimensions of square B. The area of squ

denis23 [38]

Answer:

The side of square A is 30 cm.

Step-by-step explanation:

Given that,

The dimensions of square A are three times the dimensions of square B.

The area of square A is 900 sq cm.

Side of square A = 3( side of square B)

Let the side of square B is b. So,

Side of square A, a = 3b

We know that, the area of square is side². So,

$(3b)^2=900\\\\9b^2=900\\\\b^2=100\\\\b=10\ cm$

Side of square A, a = 3(10) = 30 cm

Hence, the side of square A is 30 cm.

When a number is tripled,the results is -33

defon

Answer:

x = -11

Step-by-step explanation:

Considering tripled means multiplied by 3 because of tri, we know that we can use the equation 3x = -33.

To solve this we can divide both sides by 3:

3x = -33

x = -11

This gives our answer of -11.
