Mathematics
1 answer:
IrinaK [193]3 years ago
6 0

Answer:

dy/dx

= d/dx [2x² + 5x - 3]

= 4x + 5.

Hence at x = 1, dy/dx = 4(1) + 5 = 9.

The slope of the tangent is 9.

d/dx (3/x)

= d/dx (3x^-1)

= 3 * d/dx (x^-1)

= 3 * [-1 * x^(-2)]

= -3/x².

Yoo I don't understand this pls help :))<br><br>geometry ​
Luden [163]

Answer:

At the bottom of the text.

Step-by-step explanation:

The triangle is isosceles. The measure of the two internal angles J and K are equal; The misure of the external K angle (2) is half a circle minus the internal K (1). The internal angle in R is calculated by difference between 180 and twice the internal K angle (1).

1. 72° as well.

2. 180-70-70 = 40°

3. m\angle2 = 110 \rightarrow m\angle1 =70, Same as #2: 40°

4. x+2x+2x = 180 \rightarrow 5x=180 \righarrow x= 36

5. x +(x+30)+(x+30) = 180 \rightarrow 3x +60 = 180 \rightarrow 3x= 120 \rightarrow x=40

Wut is the value of m?<br><br> 7m=90
Sedbober [7]
The value of m is 12 6/7.

Explanation:
To find m, we want one m instead of 7, so we divide both sides by 7. 7m/7 = 90/7, which would be m = 12 6/7.
