Answer:

One.

Step-by-step explanation:

The reason why is because 12-5 = 7, meaning that your lowest length has to be 7. meaning, that you can only do one triangle.

Answer:

D. None.

Step-by-step explanation:

<em>The Triangle Inequality Theorem states the longest side must be shorter than the sum of the other 2 sides. The longest side ( 12 ) >= ( 7 plus  5 ) = 12  is too large.</em>

Solve the problem.<br> Find the radius of a circle that has a circumference of 942 meters.<br> m
Montano1993 [528]
Circumference is equal to diameter multiplied by pi. C=d X pi. To find the radius we need to rearrange this equation. We know what pi and the circumference are, so to find diameter we do circumference divided by pi. D=c/pi. 942/pi = 299.85. This gives us the diameter, for the radius simply divide by 2 which is 149.92 :)

Need help asap im not good at math
vladimir2022 [97]

OK.

Let g(x) = ax²

We have the point (3, 1).

Substitute x = 3 and g(x) = 1:

1 = a(3²)

9a = 1    |divide both sides by 9

a = 1/9

Therefore your answer is

g(x)=\dfrac{1}{9}x^2=\left(\dfrac{1}{3}x\right)^2
