Answer: 66.5cm

Step-by-step explanation:

2weeks--38 cm

6weeks--114cm

31/2weeks--X

Using given information it is easy to calculate rate of sunflower grow.

Use proportion

2:6=38:114

2:3.5=38:x

2X=3.5*38

X=3.5*38/2

x=66.5cm

What is the slope of a line perpendicular to the line whose equation is 4x−10y=404x−10y=40. Fully simplify your answer.
Anna007 [38]

Answer:

-  \frac{5}{2}

Step-by-step explanation:

4x -10y= 40

Let's rewrite this equation in the slope-intercept form (y= mx +c) so that we can obtain it's slope.

10y= 4x -40

Divide both side by 10:

y =  \frac{2}{5} x - 4

The product of the gradients of perpendicular lines is -1.

⅖(gradient of line)= -1

Gradient of perpendicular line

=  - 1 \div  \frac{2}{5}

=  - 1 \times  \frac{5}{2}

=  -  \frac{5}{2}
