Answer:
Step-by-step explanation:
153•0.92^x is a decaying exponential function.
In theory these functions never reach zero.
Suppose that you were willing to change the problem to read:
"What value will x have to for the first number to come within 0.0001 of zero?" Solve 153•0.92^x = 0.0001.
To do this, take the common log of both sides, obtaining
log 153 + x*log 0.92 = log 0.0001
Note that log 0.0001 = -4; log 153 = 2.18469; and log 0.92 = -0.03621.
Then we have:
2.18469 + x(-0.03621) = - 4.
Isolate the 2nd term. To accomplish this, subtract 2.18469 from both sides, obtaining:
-0.03621x = -6.18469
Isolate x by dividing both sides by -0.03621:
x = 170.8
This tells us that as x approaches +179, the quantity 153·0.92x will be within 0.0001 of zero.
Answer:
y I z
Step-by-step explanation:
We can see that y I b and z I b we can conclude also that
y I z.
If u are looking for x its 4 because if y=2 then u substitue it for y and you get -x+2=-2. to get x by its self you have to subtract 2 from both sides and u end up with -x=-4 and u have to divide -x by -1 to get rid of the negative and u get x=4
Answer:
Los lados opuestos tienen la misma longitud y los ángulos opuestos tienen la misma medida. Para encontrar el área de un paralelogramo, multiplica la base por la altura. La fórmula es: A = B * H donde B es la base, H es la altura y * significa multiplicar.
Step-by-step explanation:
Answer:
Part 1)
Part 2)
Step-by-step explanation:
Part 1) Find the measure of angle Z
we know that
In the right triangle XYZ of the figure
The tangent of the angle Z is equal to divide the opposite side to angle Z by the adjacent side to angle Z
so
substitute the given values
Part 2) Find the measure of angle Y
we know that
In the right triangle XYZ of the figure
The tangent of the angle Y is equal to divide the opposite side to angle Y by the adjacent side to angle Y
so
substitute the given values
