Determine the equation of the tangent to x− 3x +1 at the point (3,1)
Answers

Answer:
y = 3x -8
Step-by-step explanation:
We assume you want the tangent to the parabola y = x² -3x +1 at the given point. The slope is found using the derivative of the function at that point.
y' = 2x -3
At x=3, the slope is ...
y' = 2(3) -3 = 3
The equation of the line through point (3, 1) with a slope of 3 is ...
y -1 = 3(x -3) . . . . use the point-slope form of the equation for a line
y = 3x -9 +1 . . . . . eliminate parentheses, add 1
y = 3x -8

Answer:
angle ABC=72 degrees
Step-by-step explanation:
8x+6x+6x=180 degrees (all triangles contain 180 degrees)
20x=180
x=9
angle ABC=8x or (8)(9)=72 degrees
Answer:
72°
Step-by-step explanation:
Angle A = 6x
Angle B = 8x
Angle C = 6x
The sum of all interior angles in a triangle is 180°, which means angles A, B and C add up to 180:
A + B + C = 180
substitute in the values for A B and C:
6x + 8x + 6x = 180
Simplify by combining like terms:
6x + 6x + 8x = 180
20x = 180
solve for x:
20x/20 = 180/20
x = 9
Since we know x = 9 and angle B = 8x, u can substitute in the value of x to find the value of angle B:
B = 8x
B = 8(9)
B = 72°

Triangles ABC and CDE are mathmatecilly similar. work out the length of DE. WORK OUT THE LENGHT OF AB
Answers
Answer:
[tex]DE = 15[/tex]
[tex]AB = 6[/tex]
Step-by-step explanation:
Given
See attachment for triangles
Required
Determine the lengths of DE and AB
To solve for DE, we make use of the following equivalent ratio
[tex]AC : BC =CE:DE[/tex]
Substitute values
[tex]8:5 = 24:DE[/tex]
Express as fraction
[tex]\frac{8}{5} = \frac{24}{DE}[/tex]
Cross Multiply
[tex]DE * 8 = 24 *5[/tex]
[tex]DE * 8 = 120[/tex]
[tex]DE = 120/8[/tex]
[tex]DE = 15[/tex]
To solve for AB, we make use of the following equivalent ratio
[tex]AB : BC =CD:DE[/tex]
Substitute values
[tex]AB : 5 = 18 : 15[/tex]
Express as fraction
[tex]\frac{AB}{5} = \frac{18}{15}[/tex]
Multiply by 5
[tex]5 * \frac{AB}{5} = \frac{18}{15}*5[/tex]
[tex]AB= \frac{18}{15}*5[/tex]
[tex]AB= \frac{18}{3}[/tex]
[tex]AB = 6[/tex]

Answer:
m∠U = 36°
m∠V = 75°
m∠T = 69°
Step-by-step explanation:
(2x+14)+(6x+9)+(6x+3)=180
Combine like terms: 14x+26=180
Solve this equation: x=11
Use x=11 to find angles
∠U = 36°
∠V = 75°
∠T = 69°
You can add up all of these measurements to check. =180°
Answer:
The measures of the 3 angles are:Angle T = 69°Angle U = 36°Angle V = 75°Step-by-step explanation:
The Triangle Sum Theorem states that the 3 angles of a triangle must add up to 180°.
We don't know the angles of the triangle, but we do know that the sum of all three unknown angles is 180°.
We set the three expressions together as equal to 180°.
6x + 3 + 6x + 9 + 2x + 14 = 180
Simplify
14x + 26 = 180
Subtract 26
14x = 154
x = 11
Now, we check our answer for x.
6(11) + 3 + 6(11) + 9 + 2(11) + 14 = 180
69 (measure of angle T) + 75 (measure of angle V) + 36 (measure of angle U) = 180
180 = 180 ✅
Note that once we found x, would substitute it in and get the needed measures. Since the needed measures add up to 180°, we know that our answer is correct.
The measures of the 3 angles are:Angle T = 69°Angle U = 36°Angle V = 75°Find the value of x
