Answer:

no, it should be 0 because The coordinates of the y-intercept are 0, temperature at Earth's surface. I think the other answer is wrong is because the person who posted the answer put the number three into because that is question number 3.

Answer:

The b-value of the y-intercept for the equation is b=3

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem

The y-intercept is the point (0,3) ----> given problem

The x-coordinate of the y-intercept is 0

The y-coordinate of the y-intercept is 3

therefore

The b-value of the y-intercept for the equation is b=3

Enzo is studying the black bear population at a large national park.

Naddik [55]

Answer:

2,973

Step-by-step explanation:

The black bear population B(t), in the park is modeled by the following function:

$B(t) = 2500 \cdot 2^{0.01t}$

Where t is the time(in years) elapsed since the beginning of the study.

We want to determine the black bear population in 25 years time, t=25.

$B(25) = 2500 \cdot 2^{0.01*25}\\=2973.02\\\approx 2973$

There will be 2,973 black bears in 25 years time.

The diameter of Circle Q terminates on the circumference of the circle at (0,3) and (0,-4). Write the equation of the circle in

Gnesinka [82]

First, determine the center of the circle by getting the midpoint of the points given for the circumference.
midpoint = ((0 + 0)/2, (3 + -4)/2)
midpoint (0, -0.5)
Then, we get the radius by determining the distance from either of the circumferential point to the center.
radius = √(0 - 0)² + (3 +4)² = 7
The equation for the circle would be,
x² + (y + 0.5)² = 7²

Find x in the given figure if m∠AOC = 124°.

Nastasia [14]

Answer:

A) 8

Step-by-step explanation:

Add angles AOB and BOC to get angle AOC.

Since we know the value of AOC is 124 and AOB+BOC=AO

Then (8x+25)+(6x-13)=124.

Combine like terms to get 14x+12= 124.

Solve for x by subtracting 12 from 124, then divide the answer by 14.

A freshwater stream flows into the ocean, as shown in the diagram. Which statement correctly describes how the stream affects th

gizmo_the_mogwai [7]

I can't see any diagram but the correct statement should be:
"Salinity decreases because the stream adds freshwater to the ocean"

The other statements are false.
F Salinity increases because the stream adds salt to the ocean
T Salinity decreases because the stream adds freshwater to the ocean
F Salinity increases because the stream adds freshwater to the ocean
F Salinity remains the same because the steam adds freshwater to the ocean
