Answer:

The puppy weighed 6 pounds at birth

Step-by-step explanation:

You go from 4 to 0...seeing as the weight is changing by 2.5..you subtract 2.5 by 16, 4 times in order to get the birth weight.

16 - 2.5= 13.5 - 2.5 = 11 - 2.5= 8.5 - 2.5 =6

What is the distance between (-2 1/2,-3) and (1,-3

satela [25.4K]

Answer:

$3\frac{1}{2}\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$(-2\frac{1}{2},-3)\ and\ (1,-3)$

Convert mixed number to an improper fraction

$2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}$

we have

$(-\frac{5}{2},-3)\ and\ (1,-3)$

substitute the values in the formula

$d=\sqrt{(-3+3)^{2}+(1+\frac{5}{2})^{2}}$

$d=\sqrt{(0)^{2}+(\frac{7}{2})^{2}}$

$d=\frac{7}{2}\ units$

Convert to mixed number

$\frac{7}{2}\ units=\frac{6}{2}+\frac{1}{2}=3\frac{1}{2}\ units$

Problem 4:

4a = -15

4b = -75

4c = 125

Problem 5:

5a = -5

5b = 95

5c = -19 $\frac{1}{3}$

Step-by-step explanation:

<em> See attached for my work. </em>

For problem 4, we substitute the different values given for x and solve.

For problem 5, we set the function equal to the given values and solve.

Answer:

f(x) = x² -3
g(x) = 6x +7
h(x) = 3^x

Step-by-step explanation:

f(x) is copied from the problem statement.

g(x) is a symbolic representation of the English wording, using x to represent "a number."

h(x) is the exponential function that corresponds to the geometric sequence in the table. It has a common ratio of 3, and a multiplier of 1 at x=0.
