where

y is the dependent variable which is yield in this case.

x is the independent variable which is fertilizer in this case

m is the coefficient of the fertilizer whose value is 1.150 from the given values.

12%

Step-by-step explanation:

Profit = total selling price - cost price

(28 - 25) x 12 = 36

Percentage profit = (profit / cost price) x 100

Cost price = 25 x 12 = 300

Answer:

The slope is 0.

Step-by-step explanation:

Suppose we have two points in a data set, the slope is given by the change in the output divided by the change in the input.

In this question:

Two points: (0,-20) and (1,-20)

Change in the output: -20 - (-20) = -20 + 20 = 0

Change in the input: 1 - 0 = 1

Slope: 0/1 = 0

The slope is 0.

Answer:

I might be in highschool, but I'm sure I can still help.

Step-by-step explanation:

See the 45 degree angles? that means they're equal sides. So 4v2 = 5.65, right? so if you take 180 - 5.65, and then divide by two, you should have the length to each of those sides. They're equal, remember. So, the answer would be 180 - 5.65 = 174.35. 174.35 / 2 = 87.175. In this case, k = 87.175 :)

Answer:

mUC=70°

Step-by-step explanation:

The angle (87) formed by two chords (US and TS) is half the sum of the intercepted arcs(104 and mUC):

87=(1/2)(104+mUC)

174=104+mUC

mUC=70°

Find the midpoint of the diameter to find the center

mid-point formula

[tex](\frac{(x_{1} +x_{2)} }{2} ,\frac{(y_{1} +y_{2} )}{2} )[/tex]

Using points (4,5) and (10,1)

[tex](\frac{4+10}{2} , (\frac{5+1}{2} )\\(\frac{14}{2},\frac{6}{2}) \\\\(7,3)[/tex]

The coordinates of the center of the circle are (7, 3).

Given that, in a circle, the coordinates of the endpoints of a diameter are (4,5) and (10,1).

A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments.

The formula to find the midpoint of line segment is (x, y) = [(x1+x2)/2, (y1+y2)/2]

The center of the circle is midpoint of a diameter

Here, (x, y) = ((4+10)/2, (5+1)/2)

= (14/2, 6/2)

= (7, 3)

Therefore, the coordinates of the center of the circle are (7, 3).

The actual area of the apartment will be 960 square feet.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

There is no effect of dilation on the angle.

A blueprint shows an apartment with an area of 15 square inches.

If the blueprint's scale is 1 inch : 8 feet.

Then the scale factor will be 8/1 feet per inch.

Then the actual area square footage of the apartment will be

Actual area = 15 x (scale factor)²

Then the actual area of the footage will be

Actual area = 15 x (8/1)²

Actual area = 15 x 64

Actual area = 960 square feet

Thus, the actual area of the apartment will be 960 square feet.

y=72.5 or 73

srry I can’t help with question 2. I don’t know how

Let a (n) denote the n-th term of the sequence. Since the terms form an arithmetic sequence, you have

a (n) = a (n - 1) + d

for some fixed constant d. You can write any term in the sequence as a function of the first term:

a (n) = [a (n - 2) + d] + d = a (n - 2) + 2d

a (n) = [a (n - 3) + d] + 2d = a (n - 3) + 3d

and so on, down to

a (n) = a (1) + (n - 1) d

so given that a (11) = 57 (so that n = 11), you have

a (1) + 10d = 57 … … … [1]

The sum of the first and fourth terms is 29:

a (1) + a (4) = 29

but we can write a (4) in terms of a (1) :

a (1) + [a (1) + 3d] = 29

which gives us another equation in a (1) and d :

2 a (1) + 3d = 29 … … … [2]

Now solve [1] and [2] :

-2 (a (1) + 10d) + (2 a (1) + 3d) = -2 (57) + 29

-17d = -85

d = 5

a (1) + 10d = a (1) + 50 = 57

a (1) = 7

Then the n-th term of the sequence is given by

a (n) = 7 + 5 (n - 1) = 5n + 2
