Answer:

x = ± √5

Step-by-step explanation:

Please indicate exponentiation by using the symbol " ^ ":

5x^2 + 25x = 0

Divide all three terms by 5. We get:

x^2 + 5 = 0, or x^2 = -5

Then x = ± √5

The gradiant y=2x³-5x+1 at point (2,7)

olga2289 [7]

Given:

The equation of the curve is:

$y=2x^3-5x+1$

To find:

The gradient (slope) of the given curve at point (2,7).

Solution:

We have,

$y=2x^3-5x+1$

Differentiate the given equation with respect to x.

$y=2(3x^2)-5(1)+(0)$

$y'=6x^2-5$

Now we need to find the value of this derivative at (2,7).

$y'_{(2,7)}=6(2)^2-5$

$y'_{(2,7)}=6(4)-5$

$y'_{(2,7)}=24-5$

$y'_{(2,7)}=19$

Therefore, the gradient (slope) of the given curve at point (2,7) is 19.

Aiden knows the length of only one side of his garden. He says he will be able to find the area knowing only one aide. Explain h

Snowcat [4.5K]

This is possible providing the garden is in the shape that has equal sides, such as a square or an equilateral triangle.

Area of a square is found by multiplying one side to the other, which would be the same as multiplying two same numbers.
