Answer:

AOB and COD

Step-by-step explanation:

got the same question that was missing a different part

For triangles AOB and COD, angle 1 is equal to angle 2, as they are vertical angles.

AO = OC and BO = OD because it is given that diagonals bisect each other.

The triangles AOB and COD are congruent by SAS postulate.

Similarly, triangles AOD and COB are congruent.

By ________, angle ABD is equal to angle CDB and angle ADB is equal to angle CBD.

As the alternate interior angles are congruent, the opposite sides of quadrilateral ABCD are parallel.

Therefore, ABCD is a parallelogram.

vlabodo [156]

Answer:

g = 0 or g = -1/2

Step-by-step explanation:

Solve for g:

8 g^3 - 2 g^2 = 2 g^3 - 5 g^2

Subtract 2 g^3 - 5 g^2 from both sides:

6 g^3 + 3 g^2 = 0

Factor g^2 and constant terms from the left hand side:

3 g^2 (2 g + 1) = 0

Divide both sides by 3:

g^2 (2 g + 1) = 0

Split into two equations:

g^2 = 0 or 2 g + 1 = 0

Take the square root of both sides:

g = 0 or 2 g + 1 = 0

Subtract 1 from both sides:

g = 0 or 2 g = -1

Divide both sides by 2:

Answer: g = 0 or g = -1/2

Baby born 7 lbs by 10 he was 84 lbs. Write a formula for his weight as a linear function.

Yakvenalex [24]

The formula for weight in linear function is y= 7.7x + 7

Step-by-step explanation:

Given that,

The weight of the born baby = 7 lbs
The weight of the baby at 10 years = 84 lbs.

To find the linear function, the rate of change of weight must be calculated.

To find the rate of change of the baby's weight:

The change in the weight is from 7 lbs to 84 lbs.

The total change = 84 - 7 =77
The rate of change = 77 / 10 years = 7.7

Therefore, the rate of change of weight of the baby is 7.7 lbs.

This means that, every year the weight has been increased by 7.7 lbs and in 10 years the baby gained a weight of 84 lbs.

From this information, the linear function is given as :

Total weight = 7.7(number of years) + born weight.

⇒ y= 7.7x + 7

where,

The born weight is 7 lbs.
y is the total weight of the baby
x is the number of years
