Answer: <u> </u><u>x</u><u> </u><u>is</u><u> </u><u>4</u><u>6</u><u>°</u><u> </u>
Step-by-step explanation:
• Let's first find Angle ACB
• From alternative angles, x = Angle BAC.
• Since AB = AC, then Angle ABC = Angle ACB
Step-by-step explanation:
if x is equal to - 1
Then
2x² + 5x + 6
= 2* ( -1)² + 5 * (- 1) + 6
= 2 - 5 + 6
= 8 - 5
= 3
Hope it will help :)❤
Answer:
44
Step-by-step explanation:
This is an exponential equation that can be represented by the following:
f(x) = a(b)^x
In this case...
25143 = a(0.66)^3
25143 is the population after 3 hours.
3 is the amount of time in hours.
0.66 represents the percent of the population remaining after each hour (66% as there is a 34% decline each hour).
We must solve for a, which is the initial population.
First, simplify (0.66)^3 to 0.2874.
25143 = 0.2874a
Now divide both sides by 0.2874 to isolate a.
a = 87455
There were initially 87,455 people within the city. I wouldn't want to be in that place!
Answer with Step-by-step explanation:
We are given that an equation of curve
We have to find the equation of tangent line to the given curve at point
By using implicit differentiation, differentiate w.r.t x
Using formula :
Substitute the value x=
Then, we get
Slope of tangent=m=
Equation of tangent line with slope m and passing through the point is given by
Substitute the values then we get
The equation of tangent line is given by
This is required equation of tangent line to the given curve at given point.
