Find the slope of the curve y=-3x-x^2 at the point (-1,2)

Mathematics
1 answer:
Elodia [21]3 years ago

Answer:

slope = - 1

Step-by-step explanation:

The slope of the curve m is measured by

m = \frac{dy}{dx} at x = a

Differentiate using the power rule

\frac{d}{dx} (ax^{n} ) = nax^{n-1}

Given

y = - 3x - x², then

\frac{dy}{dx} = - 3 - 2x

x = - 1 → \frac{dy}{dx} = - 3 - 2(- 1) = - 3 + 2 = - 1 ← slope at (- 1, 2 )

Answer:

g=56

Step-by-step explanation:

In similar shapes, corresponding sides are always in the same ratio.

For example,

if the sides in triangle 1 were a and b, and triangle 2 had side lengths c and d, c and a had the same ratios, and b and d had the same ratios

and triangle 1 was similar to triangle 2, the ratio between the sides of the triangles would be

a/c, which is also equal to b/d

What that means is that in this situation, 8/5=g/35.

8/5=g/35

Cross multiply.

(8)*(35)=g*(5)

280=5g

g=56

WHT IS 2/3 TIMES 4/5
Vinil7 [7]
The answer would be 8/15. You multiply the numerators which gives you 8 and the denominators which gives you 15, since 2 times 4 is 8 and 3 times 5 is 15.

1) All cars are blue. (2) All pigs have wings. Therefore, (3) All buses have three wheels. Question 2 options: Passes the true p
Elan Coil [88]

Answer:

Fails the true premises test and fails the proper form test

Explanation:

A valid argument must pass the true premises test and the proper form test.

True premises test checks to see if what the premises is saying is true about the world, example- pigs do not have wings and so the argument fails the true premises test. Proper form test assumes the premises is true and then checks to see if a valid conclusion was drawn based on the premises(even though it might fail the true premises test and may not be true about the world)
