Step-by-step explanation:

MC : BC : MB = 1 : √3 : 2

MC : BC = 1 : √3

12 : BC = 1 : √3

BC = 12 : 1/√3

BC = 12 × √3/1

BC = 12 × √3

BC = 12√3

MC : MB = 1 : 2

12 : MB = 1/2

MB = 12 : 1/2

MB = 12 × 2/1

MB = 12 × 2

MB = 24

AB = 2BD

AB = 2CD√3

AB = 2(½BC)√3

AB = 2(½ × 12√3) √3

AB = 2 × 6√3 × √3

When a triangle is rotated and dilated by a scale factor, the new triangle formed has the same shape but different size of the original triangle. However, all its corresponding angles remains congruent.

Thus, for triangles ABC and NML to be similar to each other, since we already known each have one congruent right angles, the additional information needed are:

Answer:

= ax + b ln x - c/x + C

Step-by-step explanation:

Recall:

integral a dx = ax + C

integral 1/x dx = ln x + C

integral x^(n) = [x^(n +1)]/(n + 1) + C

Also:

c = variable in this problem

C = constant you add when you integrate

Separate each term of the numerator and set it over the denominator.

integral (ax^2 + bx + c)/x^2 dx =

integral [(ax^2)/x^2 + (bx)/x^2 + c/x^2] dx

Simplify each term and separate into the sum of 3 integrals.

= integral (a dx) + integral (b/x dx) + integral (c/x^-2) dx

= ax + b ln x + (cx^-1)/(-1) + C

= ax + b ln x - c/x + C

The height for w = 3 is:

[tex]h_1(3) = 2.5 + \frac{4}{10}*3 = 3.7[/tex]

So the height at the end of week 3 is 3.7 inches.

For plant 2 the equation is:

The height for w = 3.

[tex]h_2(3) = 2.5 + \frac{1}{5}*3 = 3.1[/tex]

So the height at the end of week 3 is 3.1 inches.

If Jay spends 40 at the store, the number of points he will earn is; 10 points

Let the number of rewards points a customer earns be y

Let the amount of money, in dollars, that the customer spends at the store be x.

Since the number of rewards points a customer earns varies directly with the amount of money, in dollars, that the customer spends at the store, then we can say that;

y ∝ x

Thus;

y = kx

where k is the constant of proportionality.

We are given x = 15 when y = $60. Thus;

60 = 15k

k = 60/15

k = 4

The equation in point slope form is y-1 = 1/4(x - 12)

The formula for calculating the equation of a line is expressed as;

y = mx + b

m is the slope

b is the intercept

Slope = 1+3/12+4

Slope = 4/16

Slope = 1/4

For the intercept

1 = 1/4(12) + b

b = 1 - 3

b = -2

The standard form is:

4y - x = -8

We know that the point-slope equation of the line is:

y - 1 = (1/4)*(x - 12)

Expanding the right side, we get:

y - 1 = (1/4)*x - 3

Now we can move the term with x to the left side:

y - (1/4)*x = +1 - 3

y - (1/4)*x = -2

Now we can multiply both sides by 4:

4y - x = -8

The area of the enlarged picture on the wall is gotten as; D: 486 in²

The formula for Linear scale factor is;

L.S = Image distance/object distance

Thus, from the attached image, we can find the Linear scale factor as;

L.S = OL'/OL

L.S = 54/ 12

L.S = 9/2

Area scale factor is equal to the square of linear scale factor. Thus;

Area scale factor = (9/2)²

Area scale factor = 81/4

Now,

81/4 = Area of larger rectangle/Area of smaller rectangle

Area of the smaller rectangle = 4 ×6 = 24 in²
