Answer:
Step-by-step explanation:
320t=500(t-1.5)
320t=500t-750
-180t=-750
t=25/6
t=4+1/6 hours
So Colby catches up 4 1/6 hours after Shelby left. Since she left at 9am
9+4hours + 10 minutes. So they have travelled the same distance at 1:10pm
Find an equation of the tangent line to the curve at the given point. y = x3 − 3x + 2, (3, 20)
Answer:
[tex]y - 20 = 24(x - 3)[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line, in point-slope form, has the following format:
[tex]y - y_0 = m(x - x_0)[/tex]
In which the point is [tex](x_0,y_0)[/tex] and the slope is m.
(3, 20)
This means that [tex]x_0 = 3, y_0 = 20[/tex]. So
[tex]y - y_0 = m(x - x_0)[/tex]
[tex]y - 20 = m(x - 3)[/tex]
Slope:
The slope is the derivative of the function at the point:
The function is:
[tex]y = x^3 - 3x + 2[/tex]
The derivative is:
[tex]y^{\prime}(x) = 3x^2 - 3[/tex]
At the point, we have that [tex]x = 3[/tex]. So
[tex]m = y^{\prime}(3) = 3*3^2 - 3 = 27 - 3 = 24[/tex]
So the equation to the tangent line to the curve a the point is:
[tex]y - 20 = 24(x - 3)[/tex]

Answer:
The answer would be 150 degrees.
Step-by-step explanation:
When looking at the problem you can see that you have two parallel lines and a transversal. Since the two lines are parallel, this allows alternate interior angles to form, i.e. <A and <B.
Since angle A and B are alternate interior angles, you can now set the two equal to each other.
So, in order to find out what x equals, you have to set the two equations equal to each other.
8x-10=3x+90
Next, solve the new equation.
8x-10=3x+90
Add 10 to both sides.
8x=3x+100
Subtract 3x from both sides.
5x=100
Divide both sides by 5 and you'll get your answer.
x=20
Now that you know what x equals, you can substitute it into the equation for B.
<B= 3(20)+90
60+90= 150
<B=150 degrees
That gives you your answer of <B = 150 degrees.
To check your work you can also substitute x into the equation for <A.
<A= 8(20)-10
160-10= 150
<A=150 degrees.
Therefore, you have just proved that the answer is 150 degrees.

In the figure below, lines A and B are parallel. Find the m∠5 if m∠1 = 75° and m∠3 = 40°
Answer:
Angle 5 is 75 degrees
Step-by-step explanation:
angle 1 is congruent to angle 5
so angle 5 is also 75 degrees.
The measure of angle 2 and 5 are 65° and 85° respectively.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
Given that, lines A and B are parallel.
Here, m∠1 = 75° and m∠3 = 40°
Now, x+m∠2+m∠3=180°
x=m∠1 (Vertically opposite angles)
x=75°
75°+m∠2+40°=180°
m∠2+115°=180°
m∠2=65°
m∠2=m∠4=65° (Interior alternate angles are equal)
Now, m∠4+m∠3+m∠5=180°
65°+40°+m∠5=180°
m∠5=85°
Therefore, the measure of angle 2 and 5 are 65° and 85° respectively.

okay so for some reason my mind went completely blank and forgot how to do pathagoream theorem. so like could you tell me the steps please
Answer:

Step-by-step explanation:
Pythag Theorem is Leg² + Leg²= Hypotenuse²
So I set it up as: x² + 9²=15²
Then solved and got: x² + 81 =225
Then I subtracted 81 on both sides and got: x² = 144
Then squareroot each side to undo the x² and got x=12
