25POINTS!!!

Anastasy [175]

i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point.

So t is perpendicular to JL

let l be the tangent line through L. Then l is perpendicular to JL

ii. So t and l are 2 different lines, both perpendicular to line JL.

2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.

Remark. Draw a picture to check the steps

A gardener wants to try different combinations of fertilizer (none, 1 cup, 2 cups) and mulch (none, wood chips, pine needles, pl

sattari [20]

Answer:

Step-by-step explanation:

First lets identify the number of treatments possible.

1st possibility: no fertilizer, no mulch

2nd possibility: no fertilizer, wood chips

3rd possibility: no fertilizer, pine needles

4th possibility: no fertilizer, plastic

5th possibility: 1 cup fertilizer, no mulch

6th possibility: 1 cup fertilizer, wood chips

7th possibility: 1 cup fertilizer, pine chips

8th possibility: 1 cup fertilizer, plastic

9th possibility: 2 cup fertilizer, no mulch

10th possibility: 2 cup fertilizer, wood chips

11th possibility: 2 cup fertilizer, pine chips

12th possibility: 2 cup fertilizer, plastic

Or we can simply calculate no. of possibilities by elements in set a x elements in set b

Total no. of possibilities = 3 x 4 = 12

To find no. of plants for each treatment divide total number of plants by the total treatments possible.

No. of plants for each treatment = total number of plants/ total number of treatments possible

No. Of plants for each treatment = 60/12

No. of plants for each treatment = 5

Which step is included in the graph of the function f(x)=[x-1]? (the brackets are ceiling functions symbols)

KiRa [710]

we are given

f(x)=[x=1]

where bracket means ceiling functions

we know that

Ceiling function returns the least value of the integer that is greater than or equal to the specified number

so, we can check each options

option-A:

$-4\leq x$

At x=-4:

f(x)=[-4-1] =-5

For x<-3:

Let's assume

x=-3.1

f(x)=[-3.1-1] =[-4.1]=-5

so, this interval is TRUE

option-B:

$-2\leq x$

At x=-2:

f(x)=[-2-1] =-3

For x<-1:

Let's assume

x=-1.1

f(x)=[-1.1-1] =[-2.1]=-3

so, this is FALSE
