How do I know when a dog is pregnant
chubhunter [2.5K]
PHYSICAL changes.
In the final third (weeks 6-9) of pregnancy, the dog’s belly becomes rounded and distended. Her mammary glands start to develop and become more obviously swollen, as they get ready to produce milk.
Behavioral changes.
APPETITE changes.
Towards the end of pregnancy, the dog’s will womb grow larger and take up more space in her belly. She won't be able to accommodate large meals, so she'll start wanting to snack, eating a little at a time more frequently.
NESTING
Watch for nesting. When it is nearly time for her to deliver the pups, the dog may start to nest. [3] She will gather blankets or clothing in a secluded place as she prepares a suitable safe warm environment for her imminent new arrivals.
The exact timing of nesting varies from 2-3 weeks to 2 - 3 days prior to giving birth.

Graph the image of this figure after a dilation with a scale factor of 3 centered at (-7,-6)
Yuri [45]
Given that the triangle is dilated by factor 3, the image will be found as follows;
The object is at:
A(-7,-3), B(-3,-2), C(-4,-5)
when the image was enlarged the new coordinates will be:
A'=3(-7,-3)=(-21,-9)
B'=3(-3,-2)=(-9,-6)
C'=3(-4,-5)=(-12,-15)
since the image is centered at the point (-7,-6), the final point will be at:
A"=[(-21+-7),(-9+-6)=(-28,-15)
B''=[(-9+-7),(-6+-6)]=(-16,-12)
C''=[(-12+-7),(-15+-6)]=(-19,-17)
thus the coordinates of the final image are:
A''(-28,-15),B''(-16,-12),C''(-19,-17)

A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The membe
Rzqust [24]

Answer:

The equation that represents the relationship between the number of T-shirts ordered, the number of colors on the shirts, and the total cost of the order  is Y = $225 +  X × $50

Where;

Y = The total cost of the order

X = The number of colors on the shirts

Step-by-step explanation:

The number of T-shirts required by the members of the school choir = 75

The amount charged by the printing company per shirt = $3

The charge for each color to be printed on the shirts = $50

The number of T-shirts ordered = 75

The charge per shirt = $3

The number of colors on the shirts = X

The fee per color on the shirts = $50

The total cost of the order = Y

Therefore, we have;

The basic cost of printing the 75 shirts = The charge per shirt × The number of T-shirts ordered

∴ The basic cost of printing the 75 shirts = $3 × 75 = $225

The total fee of the added colors to the shirt = The number of colors on the shirts × The fee per color on the shirts

∴ The total fee of the added colors to the shirt = X × $50

The total cost of the order, Y = The basic cost of printing the 75 shirts + The total fee of the added colors to the shirt

∴ Y = $225 +  X × $50

The equation is therefore;

Y = $225 +  X × $50.
