1. James did an experiment. He started out with 640 bacteria cells. He found that the growth rate of the bacteria
cells was 5.3%. Sketch the graph that represents the situation. Label the y-intercept and the point that
represents the projected bacteria population 25 h from the time James started the experiment.
2.The function f(x) = 150(1.3)
t
represents the number of bikes sold at Peer’s Bike store in months. The graph
represents the amount of bikes sold at Cycles R Us bike store in the same time period.
Answer:
y = 2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
Step-by-step explanation:
b = 640
r = 5.3% = 0.053
t = 25
y = 640 ( 1 + 0.053)^25
y = 640 ( 1.053)^25
y = 2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)

Answer:
a° = 41°
b° = 139°
Step-by-step explanation:
a° = ∠DB
a° = 41°
b° + 41° = 180°
b° = 180° - 41°
b° = 139
A bike tire just ran over a nail, and it is losing pressure at a rate of 5% every minute. The tire pressure is currently 900 kilopascals. What will it be in 7 minutes?
9514 1404 393
Answer:
629 kilopascals
Step-by-step explanation:
The tire pressure is given by the exponential function ...
p(t) = 900·0.95^t
where t is in minutes and p is in kilopascals.
p(7) = 900·0.95^7 ≈ 629 . . . . kilopascals

In ΔFGH, f = 880 inches, g = 450 inches and h=890 inches. Find the measure of ∠G to the nearest degree.
Answer:
29
Step-by-step explanation:
Delta math
The measure of the angle G will be equal to 27.50°.
What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry. The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that in ΔFGH, f = 880 inches, g = 450 inches, and h=890 inches.
The value of the angle G will be calculated as,
g² = h² + f² -2hfcosG
450² = (890)² + (880)² - 2(890)(880)cosG
202500 = 792100 + 774400 + 1566400cosG
cosG = ( 1364000) / ( 12 x 890 x 880 )
cosG = 0.87
G = cos⁻¹(0.87)
G = 27.50°
Therefore, the measure of the angle G will be equal to 27.50°.

.A 15 m ladder rests against a wall at an angle of 60° with the ground. How far is the
foot of the ladde from the wall?
9514 1404 393
Answer:
7.5 m
Step-by-step explanation:
The cosine relation applies.
Cos = Adjacent/Hypotenuse
cos(60°) = (distance to wall)/(15 m)
distance to wall = (15 m)cos(60°) = (15 m)(1/2) = 7.5 m
The foot of the ladder is 7.5 m from the wall.
find the difference
1. 4-3/5
2.5-4/7
3.6-2/3
4.5-7/8
5.7-2/5
1) with 3/5 as a fraction one whole number can be written as 5/5
so you could rewrite 4 as 3 and 5/5 now subtract 3/5 and you are left with
3 and 2/5
2) one whole number can be written as 7/7
Now you have 4 and 7/7 minus 4/7 to get 4 and 3/7
Using the same steps for the rest:
3) 5 and 3/3 -2/3 = 5 and 1/3
4) 4 and 8/8 - 7/8 = 4 and 1/8
5) 6 and 5/5 - 2/5 = 6 and 3/5
A membership to a movie night club costs $10 plus $2 per movie. Write the equation in slope intercept form to represent the situation
The equation in slope-intercept form is y = 2x + 10.
Option A is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Cost of membership = $10
Cost per movie = $2
The total cost for x movie.
= 10 + 2x
This can be written as,
y = 2x + 10
This is a slope-intercept form.
Where 2 is the slope.
Thus,
The equation is y = 2x + 10.

Answer:
1: height is 28/3 (9 1/3)
2: Base is 25/2 (12 1/2)
3: Height is 59/4 (14 3/4)
Step-by-step explanation:
Since the formula to find the area of a pallelogram is A=base × height
I divided the area by either the Base or the height (depending which one the problem had gave me)
Therefore 147 will be divided by 15 3/4.
Then 140 5/8 will be divided by 11 1/4.
Finally 151 3/16 would be divided by 10 1/4.
