Answer:

y-intercept is the weight of the animal at birth (when x = 0)

Step-by-step explanation:

y=3.86x+15

The slope (gradient) of the function is 3.86

The y-intercept of the function is 15

Therefore, the y-intercept is the weight of the animal at birth (when x = 0)

The graph shows the cube root parent function.
diamong [38]

Considering the graph of the cube root parent function, it is found that the correct statement is given by:

D. It is always increasing.

<h3>When a function is increasing?</h3>

A function is increasing when the vertical axis of the graph gets higher as we move the horizontal axis from left to right.

In this problem, the above statement is true for the entire function, hence option D is correct.

Inessa [10]

Answer:

d=1/2

Step-by-step explanation:

2d +  \frac{7}{6}  - d -  \frac{5}{3}  = 0 \\ 2d - d =  \frac{5}{3}  -  \frac{7}{6}  \\ d =  \frac{10}{6}  -  \frac{7}{6}  \\ d =  \frac{3}{6}  \\ d =  \frac{1}{2}

A county's population in 1991 was 147 million. In 1998 it was 153 million. Estimate the population in 2017 using the exponential
aliina [53]
Let t=number of years since 1991.
Then 
P(t)=147 e^(kt)   ... in millions
P(0)=147 e^(0)=147
P(7)=147 e^(7k)=153
e^(7k)=(153/147)
take ln both sides
ln(e^(7k))=ln(153/147)
7k=0.0400 => k=0.005715

Year 2017=>t=2017-1991=26
P(26)=147e^(26*.005715)=170.55
Answer: in 2017, the projected population is 170.55 millions.
